Discovery Returns, Mission Accomplished

So what did they get done, besides the usual goofy zero gravity pics?





Plenty! They installed the main components of the Kibo science lab, the largest module on the station. Below is the interior of the lab:

NASA, Astronauts Celebrate Successful Mission

Seven astronauts flew space shuttle Discovery back to NASA's Kennedy Space Center on Saturday to end the latest construction mission to the International Space Station.

Commander Mark Kelly and Pilot Ken Ham were at the controls of Discovery as it glided through Florida skies to touch down on time at 11:15 a.m. EDT.

Kelly, Ham and Mission Specialists Karen Nyberg, Ron Garan, Mike Fossum and Japan's Akihiko Hoshide spent 14 days in orbit installing the Japanese Pressurized Module to the space station. The module is the largest section of the Japanese laboratory called "Kibo," or hope. Garrett Reisman also returned onboard Discovery. He spent three months living on the space station.

Talking to the news media a few hours after landing, the crew of STS-124 beamed about the flight.

"I think I have the best space shuttle crew of all-time," Kelly said.

Although there are more pieces to add on future flights, Fossum said the addition of Kibo made the station look nearly complete.

"It was a great feeling of accomplishment as we backed away (from the station)," he said.

Hoshide, one of the astronauts of the Japan Aerospace Exploration Agency, spent time on Earth monitoring Kibo's preparation for space. Saying goodbye to it in orbit was not easy.

"When we went to close the hatch, that was a tender moment, it was kind of sad," he said.

NASA and Japanese officials hailed the flight just after landing.

"I can't think of a mission really that's been better than this one," said Bill Gerstenmaier, NASA's associate administrator of Space Operations. "We're starting to break that tie to planet Earth and get out and do what exploration is."

Discovery returned to its base in good shape, said Michael Leinbach, shuttle launch director.

"It's just a terrific day here at the Kennedy Space Center." [...]

     

Kibo Lab attached, to be activated today

Yesterday, the Discovery crew unloaded the pressurized Kibo space lab from Discovery's cargo bay, and attached it to the station.


The spacewalk crew unbolted it, and two astronauts inside the station attached it to the station using a robot arm, while the spacewalk crew got on with other repairs outside the station.


Here is an illustration that shows where the Kibo lab has been attached on the station:


Today the astronauts will complete all the internal hookups, and open the lab up. Here is some information from NASA's mission summary .PDF file:

NASA Mission Summary, SPACE SHUTTLE DISCOVERY (STS-124)

FACTS & FIGURES

• STS-124 is the 123rd space shuttle flight, the 26th flight to the station, the 35th flight for Discovery and the third flight in 2008.

• The Kibo laboratory—which means “hope” in Japanese—is the country’s major contribution to the station and will enhance the research capabilities of the space station.

• The JPM will be the largest habitable module on the space station and is equipped with its own airlock and robotic arm for external experiments.

• The final components of Kibo will be assembled in space on shuttle mission STS-127.

• The RMS main arm can handle up to 14,000 pounds of hardware. The small fine arm, when attached to the main arm, handles more delicate operations. Each arm has six joints that mimic the movements of a human arm.

• The JPM is 36.7 feet long and 14.4 feet in diameter, about the size of a large tour bus.

• The main arm measures 32.5 feet long, and the small fine arm measures 6.2 feet.

• Kibo experiments and systems are operated from the Japan Aerospace Exploration Agency's control center called the Space Station Integration and Promotion Center, just north of Tokyo.

• Experiments in Kibo focus on space medicine, biology, Earth observations, material production, biotechnology and communications research.

• To help prevent the glove cuts seen in recent missions from recurring, both spacewalkers will wear gloves with special patches on the thumb and index finger for the first time. The patches are made of the same protective vectran material already used in the palm of the gloves, but in a much tighter weave. In this form, the fabric is called TurtleSkin. It is up to four times more resistant to damage.

When all the components are in place, the Kibo lab unit should be configured like this:


The porch-like attachment is for performing experiments outside the station, using robotic arms. I believe the porch-platform is scheduled to brought up and added on in a future mission.

Crews to Enter Japanese Lab Today

The shuttle and station crews will open the newly installed Japanese laboratory Kibo for business today. Hatch opening is planned for 4:52 p.m. EDT. The experiment module was installed on the Harmony Node’s port side Tuesday.

After a leak check, mission specialists Karen Nyberg and Akihiko Hoshide will prepare Kibo for activation before opening the hatches. Shortly after entering Kibo with Hoshide, Expedition 17 Commander Sergei Volkov will sample the air and test for contamination. They will wear protective goggles and masks until they are sure the Japanese lab’s air is clean.

Mission Specialists Mike Fossum and Ron Garan will review procedures for their second spacewalk and sleep in the U.S. Quest airlock tonight to purge the nitrogen from their bodies. During Thursday’s spacewalk, the second of the mission, the spacewalkers will outfit the new lab and prepare the Japanese logistics module for relocation.

You can check the link for progress updates. They have already fixed the malfunctioning Zero-Gravity Space Toilet. That should make life in space a bit easier.
     

A busy day at the International Space Station

STS-124 to Conduct First Spacewalk, Install JPM

Mission specialists Mike Fossum and Ron Garan are scheduled to kick off STS-124’s first spacewalk at 11:32 a.m. EDT. During the 6-½ hour excursion, the pair will retrieve a shuttle inspection tool, service and inspect components of a solar alpha rotary joint and prepare the largest component of the Japan Aerospace Exploration Agency’s Kibo laboratory for installation on the International Space Station.

The spacewalkers’ first task is to transfer the Orbiter Boom Sensor System (OBSS) from the station’s truss to space shuttle Discovery. The OBSS, which attaches to the shuttle’s robotic arm for detailed inspection of the shuttle’s heat shield, was left at the station for STS-124 during the previous shuttle mission to provide room for the giant Kibo module in Discovery’s payload bay.

Next, the spacewalkers will prepare Kibo’s Japanese Pressurized Module (JPM) for installation. After inspecting the common berthing mechanism on the Harmony Node’s left side and opening a window cover, Fossum and Garan will work together in the shuttle’s cargo bay to remove contamination covers from the JPM’s docking surfaces. Fossum will also disconnect heater cables and remove locking bolts from the shutters of the JPM’s forward window.

For their final tasks, Garan and Fossum will move to the station’s starboard solar alpha rotary joint, which began experiencing increased vibration and power usage in the fall of 2007. Garan will install a replacement of one of the joint’s 12 trundle bearing assemblies. Meanwhile, Fossum will inspect a potentially damaged area on the joint and try out several techniques for cleaning debris from the surface of the joint’s race ring.

While Fossum and Garan work outside the orbital outpost, mission specialists Karen Nyberg and Akihiko Hoshide will use the station’s robotic arm to remove the JPM from the shuttle’s payload bay and install it on Harmony.

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.
     

Shuttle Endeavour to install "Dextre" robot arm and Kibo lab components onto the ISS

Below is an artists rendition of the new Canadian robot arm that the current shuttle mission will install on the ISS. They will also be installing a storage unit and other components of the Japanese Kibo lab, with the main part of the lab to follow on the next mission launch in May.


The Kibo lab will be the largest science lab on the station. The following is a description of the current mission from NASA (note that it was published prior to the mission, so it talks about it in the future tense):

All Aboard for STS-123: The Station Goes Global

“This is the first flight where we actually have all the partners,” said Dana Weigel, the lead station flight director. “It’s not just ‘a Japanese flight,’ or ‘a Canadian flight.’ This flight truly is the first time that it requires every single partner actively participating to make everything work. I think that’s a great milestone.”

Topping the list of milestones is the delivery of part of the Japan Aerospace Exploration Agency’s module, marking the beginning of the agency’s presence on the station. The Japanese Experiment Logistics Module, Pressurized Section – called the JLP – is really just the warm-up act for JAXA. It will contain critical avionics and serve as a storage area for experiment materials. At 14.4 feet in diameter and 12.8 feet in length, it is the smaller of two pressurized Japanese modules. Combined with other elements, they will make up Kibo, the station’s Japanese complex, named for the Japanese word for hope. Kibo’s main facility and its robotic arm are scheduled to launch on the following shuttle mission, and a "front porch" that will allow astronauts to expose experiments directly to space will be delivered later.

But small or not, what the module represents is big.[...]

They mention the Robot arm as going up in a following launch, but it's actually gone up on this flight. Assembling the robot will be part of their mission. Below are the astronauts of the Endeavour crew:

This mission will be the longest mission for a shuttle flight crew to date, scheduled to last a minimum of 16 days. You can track the latest news on the Mission's progress here:

Astronauts Enter JLP, Prepare for Spacewalk

Last time I looked, they had unloaded the Dextre robot for assembly, but were having some power supply issues with the platform it's to be assembled on.


You can read more about Dextre here:

'Dextre' Ready for Space Station Duty
It has some great links, including a link to a video about Dextre and Kibo.

Canadian robot Dextre heading to ISS

[...] The two-armed, $200-million robot is tentatively scheduled to be launched March 11 on board space shuttle Endeavour.

Daniel Rey, head of the technical team preparing Dextre, says the robot will reduce the amount of time astronauts must spend outside the space station. The robot could eliminate the need for up to a dozen spacewalks a year.

"He will free up astronauts so they can do more science and more research rather than maintenance,'' said Rey, who has worked on the Canadian Space Agency project for 10 years.

"It's easy to imagine from a half-a-dozen to a dozen sorties will be avoidable now,'' Rey said in an interview.

Dextre, short for Special Purpose Dexterous Manipulator, will perform exterior construction and tasks like changing batteries and handling experiments outside the space station.

Dextre also comes equipped with a tool holster which allows the robot to change equipment as needed "like any good handyman.''

But Rey said the 3.7-metre robot can't be compared to R2-D2 or HAL, the computer in the movie "2001: A Space Odyssey.''

"He doesn't have an artificial intelligence. . .he can be remote controlled from the ground or from the space station.''

The astronauts who will operate the robot's rotating joints, torso and five cameras have already been trained at the space agency, just outside Montreal.

Dextre is the third and final component of the mobile servicing system developed by Canada for the space station.

It can either be attached to a mobile base which runs on rails along the exterior of the station or it can be connected to Canadarm2 like a snap-on tool.

Long life for new robot

The robot, which has a 15-year lifespan, will be installed during three of the five spacewalks planned in March. [...]

Fascinating. You can read the whole article for more details.
