NASA Cargo Launches to Space Station aboard SpaceX Resupply Mission (Press Release)

Nearly 2.5 tons of NASA science investigations and cargo are on the way to the International Space Station (ISS) aboard SpaceX's Dragon spacecraft. The spacecraft launched atop a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida at 3:25 p.m. EDT Friday, April 18.

The mission is the company's third cargo delivery flight to the station through a $1.6 billion NASA Commercial Resupply Services contract. Dragon's cargo will support more than 150 experiments to be conducted by the crews of ISS Expeditions 39 and 40.

"SpaceX is delivering important research experiments and cargo to the space station," said William Gerstenmaier, NASA associate administrator for human exploration and operations. "The diversity and number of new experiments is phenomenal. The investigations aboard Dragon will help us improve our understanding of how humans adapt to living in space for long periods of time and help us develop technologies that will enable deep space exploration."

The scientific payloads on Dragon include investigations into efficient plant growth in space, human immune system function in microgravity, Earth observation, and a demonstration of laser optics communication. Also being delivered is a set of high-tech legs for Robonaut 2, which will provide the humanoid robot torso already aboard the orbiting laboratory the mobility it needs to help with regular and repetitive tasks inside the space station.

Dragon also will deliver a second set of investigations sponsored by the Center for the Advancement of Science in Space (CASIS), which manages the portion of the space station that is designated a U.S. National Laboratory. The investigations include research into plant biology and protein crystal growth, a field of study experts believe may lead to beneficial advancements in drug development through protein mapping.

On its way to the ISS, SpaceX's Falcon rocket jettisoned five small research satellites known as CubeSats that will perform a variety of technology demonstrations. The small satellites are part of NASA's Educational Launch of Nanosatellite, or ElaNa, mission, and involved more than 120 students in their design, development and construction. One of the satellites, PhoneSat 2.5, is the third in a series of CubeSat missions designed to use commercially available smartphone technology as part of a low-cost development effort to provide basic spacecraft capabilities. Another of the small satellites, SporeSat, is designed to help scientists study the mechanisms by which plant cells sense gravity -- valuable research in the larger effort to grow plants in space.

Dragon will be grappled at 7:14 a.m. on Sunday, April 20, by Expedition 39 Commander Koichi Wakata of the Japan Aerospace Exploration Agency, using the space station's robotic arm to take hold of the spacecraft. NASA's Rick Mastracchio will support Wakata in a backup position. Dragon is scheduled to depart the space station May 18 for a splashdown in the Pacific Ocean, west of Baja California, bringing from the space station nearly 3,500 pounds of science, hardware, crew supplies and spacewalk tools.

The ISS is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has been continuously occupied since November 2000. In that time, it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.

Climbing Legs for Robonaut 2 Headed to International Space Station (Press Release)

NASA has built and is sending a set of high-tech legs up to the International Space Station for Robonaut 2 (R2), the station's robotic crewmember. The new legs are scheduled to launch on the SpaceX-3 commercial cargo flight to the International Space Station, scheduled to launch Monday, April 14 at 4:58 p.m. EDT from Cape Canaveral Air Force Station in Florida.

These new legs, funded by NASA's Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research.

Once the legs are attached to the R2 torso, the robot will have a fully extended leg span of nine feet, giving it great flexibility for movement around the space station. Each leg has seven joints and a device on what would be the foot, called an "end effector," which allows the robot to take advantage of handrails and sockets inside and outside the station. A vision system for the end effectors also will be used to verify and eventually automate each limb's approach and grasp.

R2 To Get New Limbs in Space...

NASA Developing Legs for Space Station's Robonaut 2 (Press Release)

NASA engineers are developing climbing legs for the International Space Station's robotic crewmember Robonaut 2 (R2), marking another milestone in space humanoid robotics.

The legless R2, currently attached to a support post, is undergoing experimental trials with astronauts aboard the orbiting laboratory. Since its arrival at the station in February 2011, R2 has performed a series of tasks to demonstrate its functionality in microgravity.

These new legs, funded by NASA’s Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research.

"NASA has explored with robots for more than a decade, from the stalwart rovers on Mars to R2 on the station," said Michael Gazarik, NASA's associate administrator for space technology in Washington. "Our investment in robotic technology development is helping us to bolster productivity by applying robotics technology and devices to fortify and enhance individual human capabilities, performance and safety in space."

Once the legs are attached to the R2 torso, the robot will have a fully extended leg span of 9 feet, giving it great flexibility for movement around the space station. Each leg has seven joints and a device on what would be the feet called an end effector, which allow the robot to take advantage of handrails and sockets inside and outside the station. A vision system for the end effectors also will be used to verify and eventually automate each limb's approach and grasp.

NASA engineers have built the legs and R2 will be receiving them early next year. The new legs are designed for work both inside and outside the station, but upgrades to R2's upper body will be necessary before it can begin work outside the space station.

Technologies developed for Robonaut have led to new robotic devices for future spaceflight that also have direct applications here on Earth. For example, NASA is developing a robotic exoskeleton that could help astronauts stay healthier in space and also aid people with physical disabilities.

R5, next in NASA's Robonaut series of robots, will debut later this month when it competes in the Defense Advanced Research Project Agency's (DARPA) Robotics Challenge. During the challenge, robots will demonstrate capabilities to execute complex tasks in dangerous, degraded, human-engineered environments. Competing teams are expected to focus on robots that can use standard tools and equipment commonly available in human environments, ranging from hand tools to vehicles, with an emphasis on adaptability to tools with diverse specifications.

The International Space Station serves as a test bed for future technologies that will be vital to human exploration as NASA explores asteroids and Mars. NASA's Space Technology Program is innovating, developing, testing and flying hardware for use in NASA's future missions.

Photo of the Day... Taken on January 2, this pic shows Robonaut 2 being put through its paces as it operated on task board valves inside the International Space Station's (ISS) Destiny laboratory. What I want to know is, how do astronauts float inside this module (or any other segment aboard the ISS) without accidentally disconnecting any of the (potentially crucial) wires visible in this image? Spaceflight is indeed a hazardous business.

ROBONAUT 2... Earlier this month, NASA astronaut Mike Fossum and his Japan Aerospace Exploration Agency crewmember Satoshi Furukawa (who both returned to Earth—along with fellow Russian cosmonaut Sergei Volkov—onboard a Soyuz TMA-02M spacecraft today) spent several hours onboard the International Space Station (ISS) checking out and operating Robonaut 2...also known as R2. As shown in the photos posted with this entry, R2 does not have legs yet. NASA is planning to eventually have the robot fully-limbed so that it can conduct tasks such as performing maintenance throughout the interior of the ISS’ various modules, and even assisting astronauts during spacewalks outside of the orbiting laboratory. In the meantime, R2 will continue being tested to make sure it properly functions as the very first dexterous humanoid robot in space.

ANDROIDS... This September, NASA is planning to launch a 'special' crewmember up to the International Space Station (ISS) during the STS-133 shuttle flight. This crewmember, known as Robonaut 2—or "R2" for short—is designed to assist the ISS’ human crewmates by conducting daily chores such as setting up science experiments and wielding tools to conduct repairs. Click here for more details.



Robonaut 2 won’t initially be given free run of the ISS...but eventually, NASA plans to have R2 use its hands to move about the orbital outpost the same way astronauts push and pull their way through the ship’s interior.

...

I expect Robonaut 2 to somehow take over the space station, HAL 9000-from-2001: A Space Odyssey-style, by this Christmas.
