The Future of American Manned Space Flight

What will it look like, especially with all the budget cutting going on? Space.com asked the question of some people who might know:

What Obama and Congress Should Do for Spaceflight & Space Exploration
Amid much wrangling over how to allocate funds out of an increasingly out-of-control federal budget, the editors and writers at eight of the TechMediaNetwork's sites sought the advice of dozens of researchers, technologists, futurists, analysts and business owners in fields ranging from space and Earth science to health and technological innovation.

We asked one simple question:

If you could ask President Obama and Congress to do one thing related to your field that would be for the good of the economy and the country, what would it be and why?

[...]

At SPACE.com, we asked respondents to focus their answers on space exploration and astronomy. Here are their replies:

"If America is to fulfill its highest ambitions in space, the country must focus its attention on lowering the cost of getting there. Less expensive space access — whether through novel technologies, better manufacturing or increased reusability — will make it much more likely that we'll be able to execute thriving exploration missions to Mars, the asteroids and the moon. Some experts believe that getting to space today costs essentially the same as it did in the 1960s. Breaking free of that plateau will save the taxpayers money, grow American jobs and allow us to achieve our dreams.
George Whitesides
President and CEO, Virgin Galactic


[...]

The other responses were interesting, too. But Whitesides really made the best point, IMO. The costs have to be lowered, and free enterprise and competition will do that.

And speaking of competition, I didn't see Elon Musk, the founder of SpaceX, among the folks asked the question. His company has already created a working launch vehicle and reusable spacecraft, the Dragon capsule, that flew an unmanned test mission in December, and returned safely to Earth.


After the last space shuttle flight this summer, America will be without a manned space craft to take us into orbit. We shall have to rely on the Russians to ferry us back and forth, at great expense to us: $56,000,000.00 per ride. And the Russians plan to raise the price to $63,000,000.00 in 2014. A cost effective commercial alternative would be very timely, and greatly appreciated. Let the competition begin!

Final shuttle mission brings robot to the ISS


Robot Butler Hitching Ride to Space on Shuttle Discovery
[...] Robonaut 2, which will become the first humanoid robot in space, looks a bit like a boxer's training aid.

The $2.5 million space bot consists of a head and torso, along with a pair of dexterous arms that pack down into a puncher's pose. R2 stands 3 feet, 4 inches (1.01 meter) tall and weighs about 330 pounds (150 kilograms).

R2 is a joint project of NASA and carmaker General Motors. It's the product of a cooperative agreement to develop a robotic assistant that can work alongside humans, whether they're astronauts in space or workers at GM plants here on Earth, NASA officials have said.

The bot is made primarily of aluminum and steel. Its head houses five cameras — including one infrared camera in the mouth — to provide stereo vision and depth perception. The torso contains 38 PowerPC processors, and R2 carries a backpack that can be filled with batteries or a power conversion system.

Each of R2's arms can carry about 20 pounds (9.1 kg), and its hands have articulating fingers and thumbs. The robot, which builds on NASA's work with its first Robonaut project, should be able to use the same tools astronauts on the space station use, agency officials said.

The robot's job

Astronauts will install Robonaut 2 inside the station's U.S. Destiny laboratory and put it through some test paces. The goal is to see just what the robot helper can do — how it can work side-by-side with astronauts to make station operations run more smoothly.

"We're going to use Robonaut on orbit to learn more about how robots can take over astronaut tasks — some mundane things and then potentially some of the more dangerous tasks," said Scott Higginbotham, payload manager for Discovery's STS-133 mission.

Robonaut 2 was designed to use both internal and external interfaces, so future bots could eventually be installed on the station's exterior to aid in spacewalks and other difficult or dangerous tasks. However, R2 itself will likely stay inside, officials said, since the bot lacks protection against the extreme cold of space. [...]

It really sounds more like an experiment, than a "Butler". I'm sure we will be hearing more about it as the experiment progresses.

The real ISS "Room with a View" is installed

A while back I did a post about the new viewing window that was being installed onthe International Space Station. I posted a picture at the top of that post, of an artist's rendition of what it was supposed to look like.

Now it's installed. Here is what it actually looks like:


Not quite as bright and glamorous as the artist's rendition, is it? But close enough; it's practical and gets the job done. It allows the astronauts to see much of the Space Station's exterior without having to rely totally on cameras.

The view in this photo is, I think, the Sahara desert. But the view changes constantly, as the station orbits the earth about 16 times a day.

Space shuttle delivers viewing window to ISS



Endeavour to Deliver a Room With a View
The International Space Station has been moving steadily closer to completion for the past several years. But what house is complete without a utility room, a gym and a picture window?

During the STS-130 mission, space shuttle Endeavour will deliver the Tranquility node and its cupola, a dome-shaped extension from Tranquility made up of seven windows. They will be the last major U.S. modules to be added to the space station, and together they’ll help clear out premium workspace in other areas of the station – as well as offer a window on the world.

At 15 feet wide and 23 feet long, the Tranquility node will provide a centralized home for the station’s environmental control equipment – one of the systems that remove carbon dioxide from the station’s air, one of the station’s bathrooms and the equipment that converts urine into drinkable water, all of which is currently taking up space in the Destiny laboratory. And there’s enough room left over to house the station’s new treadmill and its microgravity equivalent of a weight machine, moving it out of the Unity node where it’s in the way whenever spacewalk preparations are going on inside the adjacent Quest airlock.

“It gives us a much needed addition to the house, so to speak,” said Bob Dempsey, lead space station flight director for the mission. “We’re getting to the point where we’re really cramped for space. You might be surprised at that, considering we’re essentially the volume of a 747 and we’ve been adding modules for the last couple of years. You might think we’d be sitting around in a big empty house. But no – every inch is really getting packed up there.”

STS-130 Commander George Zamka put it another way.

“It’s like exercising in the office,” he said. “This will be a more logical organization, more focused.”




Though the node has an intensely practical function, there are still fanciful aspects to Tranquility. For one, its name, which was chosen with the help of a naming contest on NASA.gov.

“It harkens back to the Sea of Tranquility, where humans made their very first tentative landing on the moon,” Zamka said. “They were only there for a few hours, and it was at the very limits of what human beings could do. From that beginning, we’re now putting up a node that will house the majority of the life support equipment for the station, where we’re going to have a permanent presence in space.”

But everyone agrees that the real scope for the imagination will be provided by Tranquility’s 6.5-by-5-foot annex: the cupola. Its true purpose will be to provide a true view of robotics operations on the station’s exterior – such as those that will be required when the next module, the Russian Rassvet, is added during STS-132 – and in that it will be invaluable.

“Out the window is the truth,” Zamka said. “The video views that we use now, you’re trying to stick together and have a mental image of where things are. When you look out the window, you don’t have to imagine. It’s all right there for you.”

But there’s no question that many people – including Zamka – are looking forward to looking out of it for other views.

“Just the idea of providing this great view of the station and the world beneath us is going to be pretty great,” he said. “That’s not what it’s for, but it will be spectacular.” [...]

A pretty neat combination of form and function, it's both practical and fanciful. Follow the link for more pics and information.

Is a Big Shake Up going to happen at NASA?

It looks like big changes are very likely comming their way:

Panel Urges NASA to Reset Priorities
A blue-ribbon panel is recommending that NASA shelve its goal of rapidly returning to the moon and instead focus on nurturing a robust commercial space industry that can handle short-term objectives of the nation's space program, such as ferrying cargo and crew to the international space station.

The panel, called the Review of U.S. Human Space Flight Plans Committee, headed by former Lockheed Martin Corp. Chairman Norman Augustine, was convened by the Obama administration earlier this year to provide an independent assessment of the priorities of the National Aeronautics and Space Administration. It presented its findings to the White House Tuesday.

[...]

It calls for sweeping changes in the way NASA does business and envisions a dramatically expanded role for private enterprise in human space flight in the coming decades beyond anything proposed previously.

Some of the details of the study were reported in The Wall Street Journal last month. However, a summary and excerpt of the report became available Tuesday. The panel urged NASA to shift its goal from returning to the moon and to focus instead on the more long-term objective of reaching Mars, though it didn't set any specific time frame. [...]

I don't see how they can scrap the Moon mission, and go for Mars. The moon is much closer, more realistic, less expensive, and our astronauts would need that lunar experience, I would think, before tackling a Mars mission.

But perhaps some of the changes at NASA might really be for the better. Consider this:
[...] After the report summary was released, Elon Musk, the founder of Space Exploration Technologies Corp., one of the companies vying for commercial contracts to start ferrying cargo and astronauts to the station, said sticking with NASA's current priorities "flies in the face of reason and common sense." In a teleconference with reporters, Mr. Musk also said development of his company's Falcon 9 heavy-lift launcher – which could start ferrying astronauts to the space station before the middle of the next decade for less than half of Russia's prices -- is about a year late. But "in the space business," he added, "that's early."

In addition to the emphasis on commercial solutions, the report hits heavily on the need to reorient NASA's leadership and the mindset of many of its engineers and scientists. The committee, according to the summary, "strongly believes it is time for NASA to reassume its critical role of developing new technologies" aligned with a revamped "exploration mission that will last for decades." If properly funded and executed, the report concludes, such a technical roadmap would "re-engage the minds at American universities, in industry and within NASA" for manned space efforts.

The report's opening paragraph sets the tone. America's human space flight program "appears to be on an unsustainable trajectory, " the committee found, because it is "perpetuating the perilous practice of pursuing goals that do not match allocated resources." Even before release of the summary, NASA officials were studying possible changes to existing plans, including downsizing a proposed space capsule and revising rocket programs in order to lower costs by reusing some space shuttle-derived technologies and facilities. Other NASA officials, according to a Reuters story Tuesday, have devised a 30-year stepping-stone strategy – still in its early stages -- to develop technology and generate public support with the goal of eventually reaching Mars. [...]

Read the whole article for the details. I can't be completely negative about it, some of the proposed changes actually sound pretty good. It will be interesting to see which of the proposed changes the Obama administration goes with. If they choose wisely, it could work out well in the long run.

If NASA can be straightened out, then maybe we can use a similar plan to get the rest of our government off of it's "unsustainable trajectory", and break it's habit of "perpetuating the perilous practice of pursuing goals that do not match allocated resources." Wouldn't that be great? What's good for the Space Program, might be good for Congress and the White House too!

ISS with new solar panels & full power capacity

Thanks to the crew of the recent Space Shuttle Discovery Mission, STS-119:


Space Shuttle Mission: STS-119
Space shuttle Discovery and its crew of seven safely touched down on runway 15 at NASA's Kennedy Space Center in Florida at 3:14 p.m. EDT on Saturday, March 28. The weather cooperated enough to allow the spacecraft to land on the second opportunity.

Mission Specialist Sandra Magnus also returned to Earth with the STS-119 crew. Magnus spent 129 days aboard the International Space Station as flight engineer for Expedition 18. Japanese astronaut Koichi Wakata took her place on the orbiting laboratory and will return to Earth with the STS-127 crew.

The 13-day mission included three spacewalks, about 6-hours a piece, to install the S6 truss and enormous starboard-side solar arrays. They also unfurled the arrays and performed other get-ahead tasks.

Mission STS-119's crew of seven completed a successful mission aboard the International Space Station -- increasing the orbiting laboratory's power capacity and giving it the ability to accommodate additional crew members in the future.

Up till now, the ISS could only accommodate three permanent crew members. Two of those members have a full time job running the station, leaving only one to conduct experiments. Now they will be able to have six full-time crew members, and be able to really start using those space labs for research.

New "bedrooms" and a 2nd bathroom for the ISS


I keep reading news reports about the "home makeover" for the International Space Station, talking about adding two new bedrooms and a 2nd bathroom, as if it were a house. The reality is quite different from any house you might experience here on earth.

For instance, would you call this a "bedroom"? Not by earthly standards:



It's basically a padded closet. On the right wall, you can see a thin sleeping bag stuck to the wall. That is the "bed" the astronaut uses. He/She zips themselves inside so they don't go floating around bouncing off the walls every time they move in their sleep!

As for the 2nd toilet, I think it looks kinda scary:


The Russian-made zero gravity toilet is no doubt very practical. I'm pretty sure there are sources on line that explain exactly how it works... for those who really want to know!

I got these photos from here:

Space.com: Shuttle Astronauts to Move In Aboard Space Station

Follow the link for more details and more photos of the other things they are installing, like the water recycling unit that will recycle urine into clean drinking water.

Just like home, right? But don't laugh - every home may have one, someday. Yikes.

Space Shuttle Endeavour to dock with ISS today

In fact, it's happening right now:


This mission is about expanding the International Space Station's capacity to hold a larger full time crew. Here is a photo of the Endeavour crew, and a summary of their mission:

Image above: These seven astronauts take a break from training to pose for the STS-126 crew portrait. Astronaut Christopher J. Ferguson, commander, is at center; and astronaut Eric A. Boe, pilot, is third from the right. Remaining crew members, pictured from left to right, are astronauts Sandra H. Magnus, Stephen G. Bowen, Donald R. Pettit, Robert S. (Shane) Kimbrough and Heidemarie M. Stefanyshyn-Piper, all mission specialists. Image credit: NASA

Veteran space flier Navy Capt. Christopher J. Ferguson will command the STS-126 mission aboard Endeavour to deliver equipment to the International Space Station that will enable larger crews to reside aboard the complex. Air Force Lt. Col. Eric A. Boe will serve as the pilot. The mission specialists are Navy Capt. Stephen G. Bowen, Army Lt. Col. Robert S. Kimbrough, Navy Capt. Heidemarie M. Stefanyshyn-Piper and NASA astronauts Donald R. Pettit and Sandra H. Magnus.

Magnus will remain on the station, replacing Expedition 17/18 Flight Engineer Gregory E. Chamitoff, who returns to Earth with the STS-126 crew. Magnus will serve as a flight engineer and NASA science officer for Expedition 18. Magnus will return to Earth on shuttle mission STS-119.

Endeavour will carry a reusable logistics module that will hold supplies and equipment, including additional crew quarters, additional exercise equipment, equipment for the regenerative life support system and spare hardware.

STS-126 is the 27th shuttle mission to the International Space Station.

You can read more about the mission's specific tasks here:

Station Prepares for Expanding Crew
Expanding kitchen facilities, adding more bedrooms and an extra bathroom all sound like home improvements that many homeowners have tackled. But when the “house” is the International Space Station orbiting 220 miles above Earth, things are a little more complicated than visiting the local home improvement store for materials. Just in time for its 10th anniversary, the space station will get a delivery via space shuttle Endeavour that might win a prize for out-of-this-world home makeover.

When Endeavour and crew lift off on the STS-126 mission for the 27th shuttle flight to the station, it will be packed with supplies like food and clothing for the station crew members. However, Endeavour’s major payload consists of equipment for enlarging the space station’s capacity to accommodate a six-member crew. The high-tech home improvement materials are stowed inside the Multi-Purpose Logistics Module Leonardo, which will be tucked inside the shuttle’s cargo bay.

Some of the additions aboard will be: [...]

ISS Crew Changeover and a Space Tourist

Space Tourist Richard Garriott paid 30 million
dollars for his 10-day space journey

A Russian Soyuz capsule carrying space tourist Richard Garriott, and Russian cosmonaut Yury Lonchakov and US astronaut Michael Fincke, has docked at the International space station. From The Associated Press:

Russian spacecraft docks with orbital station
KOROLYOV, Russia - An American computer game designer boarded the international space station Tuesday, floating onto the orbital outpost 35 years after his astronaut father circled the Earth on Skylab.

Richard Garriott was greeted by another man who has turned space flight into a family tradition: Russian cosmonaut Sergei Volkov, whose father is a decorated veteran of the Soviet space program.

[...]

Garriott, 47, paid a reported US$30 million to fulfill his childhood dream of space travel. Growing up steeped in space flight, his determination was only strengthened when he was told his poor eyesight would prevent him from becoming a NASA astronaut like his father.

[...]

Long rivals in the Cold War space race, Washington and Moscow often point to the space program as an example of cooperation in their otherwise difficult relationship, which reached a low point in August when Russia defeated Georgia, a U.S. ally, in a brief war.

During their stint, Fincke and Lonchakov will work to expand the capacity of the station to host a crew of six — up from three — with additional sleep spaces, a second toilet and an exercise machine. Their crewmate Greg Chamioff will be replaced by another U.S. astronaut, Sandra Magnus, who is scheduled to arrive on a space shuttle in November along with equipment for the expansion.

Sounds like it's business as usual, despite international tensions over the Russia/Georgia conflict. Can the Russia/America cooperation continue, without letting politics interfere? It seems they are determined to do just that.

From DailyTech.com:

Russia Space Director Talks Russia-U.S. Business Deal
Even though political tensions between the United States and Russia remain strained and global economic problems are causing credit crunches, space exploration will take place as scheduled, the head of Russia's space agency said over the weekend.

Roscosmos head Anatoly Perminov understands that in two short years the Soyuz space capsule will be the only transportation for astronauts to reach the International Space Station (ISS) until 2014 or 2015. Russia will need to assist the U.S. to get both astronauts and supplies to the ISS, and the ISS crew could be expanded from three people to six, which would add pressure to Russia.

"Cooperation is first and foremost international and it cannot be said that space has any boundaries," Perminov said during the press conference. [...]

The US Congress has made it legal for NASA to purchase seats aboard future Soyuz launches, despite political obstacles. Read the whole thing for more details.

I wonder if they can stay on course with this. The Orion project, our new spacecraft to replace our aging shuttle fleet, could be delayed beyond it's 2015 target date. The multi-billion dollar bailout for banks could affect NASA funding. For now it looks like plans have not changed. Russia needs the money as much as we need them to supply us with Soyuz spacecraft. We shall see as time goes along, if the arrangement, and our space budget, will hold up.

Discovery Shuttle Launch a Success: both the Shuttle and the ISS are easily seen from Earth


'Huge Day' for NASA, Japan
May 31
6:45 p.m. EDT

Commander Mark Kelly promised "the greatest show on Earth," and space shuttle Discovery delivered with a thundering, fiery arc stretching over Florida's East Coast on Saturday. The launch began a 14-day mission for Kelly and his crew of seven astronauts as they install a new Japanese-built laboratory module on the International Space Station.

As the astronauts got used to their new surroundings in space, NASA officials on Earth basked in the satisfaction of a flawless countdown and liftoff from NASA's Kennedy Space Center in Florida.

"(It was) obviously a huge day," said NASA Administrator Mike Griffin. "A huge day for the space station partnership, for the Japanese Space Agency, for NASA and, really, for the people who hoped to see the space station do what it was designed to do, to be a place in orbit where we can learn to live and work in space."

[...]

Next up for the STS-124 mission is a two-day chase across space to link up with the International Space Station. It will take the crew several hours of robotic arm maneuvers and spacewalks to connect the Pressurized Module of Japan's Kibo laboratory to the station. The 36-foot-long module is the largest habitable section to be launched to the orbiting research post.

Both the International Space Station and the Discovery shuttle are visible to the naked eye. The ISS travels a fast orbit over the earth, and sees as many as 14 sunrises and sunsets in one day! When it passes over where you live, you may have several opportunities to see it in one night. I had published the following link previously, as a way to find out when the ISS is flying over where you live:

Find out when the ISS passes over your city

If you go to the page and type in your country and the city you live in, it will give you a schedule of when the ISS will be visible to you, weather permitting. Well it now also offers you the schedule of the Discovery Shuttle too. And as the two get closer together over the next few days, you might even see them flying together right up until they dock.

When they attach the Kibo lab, I expect the station and docked shuttle will appear larger and brighter than ever. I'll be watching for it.

Space Shuttle Discovery to Launch Saturday

On the agenda for this trip will be high tech toilet repairs, and the addition of the main component of the Japanese built Kibo space lab:

Image above: A technician loads replacement parts onto space shuttle Discovery for the International Space Station's toilet. The crews of Discovery and the station will install the new components during STS-124. Photo credit: NASA/Dimitri Gerondidakis

Space Shuttle Discovery Mission STS-124
[...] May 29
New parts to fix an intermittent problem with the Russian toilet on the International Space Station arrived in the United States last night and were packed inside space shuttle Discovery well before dawn at NASA's Kennedy Space Center in Florida.

The crew of Discovery and the residents of the International Space Station will install the new parts, including a pump, during the STS-124 mission that is scheduled to launch Saturday at 5:02 p.m. EDT. The three station residents already in orbit currently are using alternatives to the toilet.

The main toilet on the station works for solid waste disposal but requires additional steps for liquid waste. It also takes two crew members and 10 minutes of maintenance after three flushes, said Kirk Shireman, deputy International Space Station program manager.

"It is very inconvenient at this time because it requires a lot of manual intervention," Shireman said.

The good news for the station is that there are no trouble signs for Discovery as it nears launch day.

[...]

Discovery's 14-day flight will carry the largest payload so far to the station and includes three spacewalks. It is the second of three missions that will launch components to complete the Japan Aerospace Exploration Agency's Kibo laboratory. The crew will install Kibo's large Japanese Pressurized Module and Kibo's robotic arm system. Discovery also will deliver new station crew member Greg Chamitoff and bring back Flight Engineer Garrett Reisman, who will end a three-month stay aboard the outpost.

You can follow the link for updates. Here is a photo of the Discovery Crew:

Seeing the International Space Station from Earth

I've been collecting photos of the ISS. This one is currently my desktop wallpaper:


I believe it's taken from the shuttle, from a few missions back.

It's also possible to photograph the ISS from the earth, but it can be hard to do, because you need a telescope, and it's moving quite fast when it passes overhead, and is typically only visible for two or three minutes. Here is the result of one attempt that succeeded:




But you don't need a telescope just to see it pass overhead, it is visible to the naked eye, as a point of light moving across the sky. With good binoculars, you might even make out some of it's features. There is a place on the web where you can enter your location or zip code, and find out when and where it will be visable from your location:



Find out when the ISS passes over your city

Have you ever wondered what's been going on at the ISS? What's coming up next? Now you can find out, by checking this link for the latest news:

ISS News Releases

I've been reading it lately. There are all sorts of things going on all the time. Currently there is an overlap of station crews, which change about every six months. The former crew is due to return to earth April 19th. And South Korea's female astronaut So-yeon Yi is making her first flight and visit to the station. She is due to return on the 19th with the former crew, via a Soyuz spacecraft.

ISS is now about 70% completed

Here are some photos taken from the Shuttle Endeavour recently, when it departed the ISS:


Above is a close-up of the Kibo lab storage unit, the circular canister on top, with the Columbia ESA lab protruding just to the left. The new robot arm is resting above. The Kibo storage unit is in a temporary location; it will eventually be moved and attached to the Kibo lab that is arriving on the next shuttle mission.


More than double the size of the ESA lab, the Japanese-made Kibo lab will be the largest laboratory on the station.It will be attached opposite the ESA lab on the right side, and the storage module will be moved on top of it.


You can see lots more photos from Endeavor's mission in the galleries here:

STS-123 Shuttle Mission Imagery

The images are available in high and low resolution. The high resolution ones make great desktop wallpaper.

The next shuttle mission, STS-124, is scheduled for May 25th:
Navy Cmdr. Mark E. Kelly will command the STS-124 shuttle mission to deliver the Pressurized Module and robotic arm of the Japanese Experiment Module, known as "Kibo" (hope), to the International Space Station. Navy Cmdr. Kenneth T. Ham will serve as the pilot. Mission specialists will include NASA astronauts Karen L. Nyberg; Air Force Col. Ronald J. Garan Jr.; and Air Force Reserve Col. Michael E. Fossum. Japan Aerospace Exploration Agency (JAXA) astronaut Akihiko Hoshide also will serve as a mission specialist.

Navy Cmdr. Stephen G. Bowen was previously named to the STS-124 crew but has been reassigned to STS-126. The change allows room for the STS-124 mission to rotate a space station resident.

Astronaut Gregory E. Chamitoff is scheduled to fly to the station as a mission specialist on STS-124. He will take Astronaut Garrett E. Reisman's place as an Expedition 17 flight engineer and return to Earth on shuttle mission STS-126.

The STS-124 mission is the second of three flights that will launch components to complete the Kibo laboratory. The mission will include two spacewalks to install the new lab and its remote manipulator system. The lab's logistics module, which will have been installed in a temporary location during STS-123, will be attached to the new lab.

STS-124 is the 26th shuttle mission to the International Space Station.

You can follow the link to see photos and profiles of the crew members. There is a total of 10 more shuttle missions planned. If all goes well, the ISS will be completed by 2010, and NASA will retire the shuttles in favor of their new Orion capsules. Their focus will then change to manned missions to the moon, and Mars.

Clarissa: a HAL type computer for the ISS?

Much of the technology portrayed in the famous science fiction film "2001: A Space Odyssey" has failed to materialize by the year 2001. The HAL 9000 computer in the movie is no exception.


Artificial intelligence (AI) is a controversial topic, with a lot of disagreement as to what actually constitutes real intelligence. Many argue that a computer like HAL is way off in the future, while others would maintain that it's closer than we think.

Whichever opinion one holds, it's clear that the science of AI is moving forward anyway. Today we may even be seeing the beginnings of what could one day lead to a HAL like computer. In fact, perhaps we already have HAL's great great grandmother! In 2005, the International Space Station got a talking computer called Clarissa to help the astronauts by reading instruction manuals to them. Maggie McKee explains it to us in this article from New Scientist:

Space station gets HAL-like computer      [published June 2005]

A voice-operated computer assistant is set to be used in space for the first time on Monday – its operators hope it proves more reliable than "HAL", the treacherous speaking computer in the movie 2001: A Space Odyssey.

Called Clarissa, the program will initially talk astronauts on the International Space Station through tests of onboard water supplies. But its developers hope it will eventually be used for all computer-related work on the station.

Clarissa was designed with input from astronauts. They said it was difficult to perform the 12,000 procedures necessary to maintain the ISS and conduct scientific experiments while simultaneously reading through lengthy instruction manuals.

"Just try to analyze a water sample while scrolling through pages of a procedure manual displayed on a computer monitor while you and the computer both float in microgravity," says US astronaut Michael Fincke, who spent six months on the station in 2004.

Clarissa queries astronauts about the details of what they need to accomplish in a particular procedure, then reads through step-by-step instructions. Astronauts control the program using simple commands like "next" or more complicated phrases, such as "set challenge verify mode on steps three through fourteen".

Kim Farrell, Clarissa project manager, simulates on-orbit use of the system in the International Space Station mock-up at Ames Research Center.

"The idea was to have a system that would read steps to them under their control, so they could keep their hands and eyes on whatever task they were doing," says Beth Ann Hockey, a computer scientist who leads the project at NASA's Ames Research Center in Moffett Field, California, US.

That capability "will be like having another crew member aboard", says Fincke. (You can see Clarissa in action in a mp4 video hosted on this NASA page.) [...]

Clarissa uses an "open mic", and is capable of understanding multiple voices of astronauts, recognizing when astronauts are talking to each other and not to it, can deal with some ambient noise, and has a high voice recognition rate of around 94%, making it a very useful and professional tool. You can read the full article for more details, and there's more videos of Clarissa on NASA's web site:

Clarissa is cutting-edge technology, and is leading the way for future voice recognition and text-to-speech applications closer to home.

Beth Ann Hockey is the project leader of the Clarissa project.
The Clarissa software program also borrows her voice.


I find the Clarissa project interesting not only for what it does now, but for what it has the potential to do in the future. The following is an excerpt from an interview with the project's leader, Beth Ann Hockey, who gives us some insight into where this is going:

WHO'S WHO AT NASA: Beth Ann Hockey

[...] NTB: How will NASA utilize Clarissa?

Hockey: It could be used widely in any area of NASA that uses procedures like these; however, spoken-language and spoken-dialogue technologies are much more general than that and can be used in all sorts of other places. For example, we had some conversations about using it for ground-maintenance crews and for developing applications for use in mission control. Any time you want to have your hands and eyes free, it will be a win. There are many times that it could be beneficial simply because you’re moving around. If you had wireless technology, plus the spoken-dialogue technology, you could move around and still be accessing information that you need.

NTB: How did Xerox contribute to this project?

Hockey: In the realistic-experimental version that we have, we worked on some technology with Xerox because one of the big ideas behind this was to have your hands and eyes free; we did not want the user to have to push a button to indicate that speech recognition should start, which is the way that some systems are designed. We needed to have the speech recognition running constantly. The system has to decide whether the speech that it’s hearing is directed at it – is it a command it should understand – or is it something it should ignore.

We got together with Jean-Michel Renders from Xerox Research Centre Europe, an expert on kernel methods, and we believed that those methods would do a better job on this problem. We worked with Renders on using the kernel methods to make this open-microphone decision, and we cut the error rate in half.

NTB: What are possible commercial applications for Clarissa?

Hockey: I just gave a talk at the V-World Summit, which is held by Nuance Communications for their developers and customers. I was invited because they see what we’re doing as the next-generation of applications in their area. Nuance is the speech-recognition engine that we use. We build the language understanding in addition to that engine. Nuance is the first stage in what we use; it takes your acoustic signal and makes a good guess at the words that signal might have been. Nuance’s main business is supporting telephone-bank-type applications. For example, if you call an airline to check flight information or if you have an automated banking application that you interact with, those are probably built with Nuance. These are the types of applications that now are commercially common.

The application that we did for the astronauts is more complicated in a lot of ways when compared to those systems, which feel like a “menu only” that you’re talking to. Our system feels like you’re having a conversation with somebody who may not be the brightest person, but it feels more like a conversation. It’s natural, as there are more of these kinds of menu-type commercial applications out there and people get used to them, to move toward a more conversational technology. This is true especially as the technology keeps maturing.

Aside from the menu-type uses for this technology, the navigating of procedures applications could be natural for doing any kind of equipment maintenance (i.e., airlines). For example, tasks in which you’d have to have your hands doing something while you’re laying underneath a piece of equipment and it’s not convenient to stop and scroll through a computer screen or flip though papers. So there already are plenty of commercial applications; we’re just carrying it to the next level.

I’ve been talking mostly about this procedure navigator, while in fact the component technologies in that are even more widely applicable. In particular, the other project on which I am the lead is called Regulus. We’re developing an open-source tool kit to try and make the creation of spoken-dialogue interfaces more accessible to regular developers. Currently, you have to have someone with expertise in language technology to be able to do this well, but we’re trying to make it so that people can take this toolkit and make their own simple-to-moderate interfaces. It’s open source – people can simply download it. We also are working on a book that will include tutorial materials on how to use that system, which should be coming out next year. If people are interested in that, they should contact us. [...]

I did a post earlier about Dragon NaturallySpeaking 9 voice recognition software, which uses the Nuance speech engine Ms. Hockey speaks of. The Nuance engine is impressive, and judging from the consumer reviews, it's regarded as the best voice recognition speech engine available. A close runner up is the Microsoft speech engine that's bundled with Windows Vista, which consumers say is nearly as accurate as Nuance's latest version.

Have you noticed the Microsoft TV commercials lately, regarding software driven by voice commands? Voice recognition and Text-To-Speech (TTS) technologies promise to be two of the Next Big Things in computer technology.

Combine it with Artificial Intelligence, and we are on our way to a HAL like computer somewhere in our future.

Dining in Space, Playing with Food



Trying to eat in zero gravity can be weird, and comical too.

I read that the astronauts on the ISS have a kitchen where there is no real cooking done. It has a dining table, but no stove. The Russians supply canned food, and the Americans supply food in sealed plastic pouches. The food is pre-cooked, and can be reheated. They eat with spoons, no knives or forks. There is no refrigerator; if they want to have a cold drink, they have to prepare it and leave it in a part of the station that is cold and go back for it later.

While living on the station, many of the astronauts develop a craving for spicey foods, even if they weren't partial to them previously. One theory is that the weightlessness of space causes congestion in the head, and so the astronauts may crave spicey foods to relieve the congestion.

And of course, there's lots of opportunity to play with one's food.

The International Space Station Progresses

Many a high-rise office building boasts about having incredible views, but I doubt there are many that can top this view from the International Space Station. Talk about a "View from the top":


It is the sun setting over the pacific ocean, as photographed from the ISS. You can download a large version of the photo here, it makes a great desktop wall paper.


The space shuttle Atlantis recently completed a mission, in which they delivered and installed a new lab unit to the ISS. The European Space Agency's Columbus laboratory is ESA's biggest single contribution to the International Space Station.

Columbus European Module
[...] The 4.5-metre diameter cylindrical module is equipped with flexible research facilities that offer extensive science capabilities. During its 10-year projected lifespan, Earth-based researchers, together with the International Space Station crew, will be able to conduct thousands of experiments in life sciences, materials science, fluid physics and a whole host of other disciplines, all in the weightlessness of orbit.

To keep costs low and reliability high, Columbus shares its basic structure and life-support systems with the Italian Space Agency's Multi-Purpose Logistics Modules (MPLM). But whereas the MPLM is aptly described as a 'space moving van' - albeit a very sophisticated moving van - the 75 cubic metres of space inside Columbus contains an entire suite of science laboratories. [...]

The following link also has more details, including a clickable thumnail link to a much larger version of the diagram above:

Columbus - Europe's lab at the International Space Station ISS
[...] As the first European laboratory devoted to long-term research in space, Columbus will further expand the science capabilities of the ISS. In its interior, the Columbus laboratory will provide accommodation for experiments in the field of multidisciplinary research into biology, physiology, material science, fluid physics, technology, life science and education. In addition, its external payload facility hosts experiments and applications in the field of space science, Earth observation and technology. [...]

You can follow the links for more fascinating details and photos.




The mission concluded successfully, and the Columbus module is now fully functional. Below is a photo of the the ISS as it exists today, a work in progress:



Bellow is an artist's rendition of what the completed station may look like:
