NASA reports Short Spacewalk Complete After Successful Installation Work

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA concluded their spacewalk at the International Space Station at 9:06pm CDT. During the spacewalk, which lasted two hours and 46 minutes, the two astronauts successfully replaced a computer relay box, and installed a pair of antennas on station to enhance wireless communication for future spacewalks.

Spacewalkers have now spent a total of 1,250 hours and 41 minutes working outside the station during 201 spacewalks in support of assembly and maintenance of the orbiting laboratory.

International Space Station Managers Give Go for Tuesday Spacewalk

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – International Space Station Program managers have given the green light for a contingency spacewalk on Tuesday by two Expedition 51 crew members to change out a multiplexer-demultiplexer (MDM) data relay box on the S0 truss that failed on Saturday morning.

The cause of the MDM failure is not known. After a review of spacewalk preparations and crew readiness throughout the day Sunday, the decision was made to press ahead with the spacewalk on Tuesday. It will be conducted by Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA.

NASA begins planning for Orion Spacecraft manned mission

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In February, NASA began an effort looking at the feasibility of putting crew aboard the first integrated flight of the Space Launch System rocket and Orion spacecraft — Exploration Mission-1, or EM-1. After weighing the data and assessing all implications, the agency will continue pursuing the original plan for the first launch, as a rigorous flight test of the integrated systems without crew. 

However, engineers will apply insights gained from the effort to the first flight test and the integrated systems to strengthen the long-term push to extend human presence deeper into the solar system.

NASA looks for ideas for a Manufacturing Laboratory in Space

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA is seeking proposals for development of a first-generation, in-space, multi-material fabrication laboratory, or FabLab, for space missions. The FabLab solicitation is issued as Appendix B of the Next Space Technologies for Exploration Partnerships (NextSTEP-2) Broad Agency Announcement. 

The FabLab development path will be implemented in three phases with the objective of the final phase to demonstrate a commercially developed FabLab on the International Space Station. This solicitation seeks responses only to Phase A, in which private industry partners will produce ground-based prototypes with a measurable ability to mature into flight demonstrations on the space station within three years.

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – SpaceX’s Dragon cargo spacecraft splashed down in the Pacific Ocean Sunday, March 19th, with more than 5,400 pounds of NASA cargo, and science and technology demonstration samples from the International Space Station.

Everything from stem cells that could help us understand how human cancers start and spread after being exposed to near zero-gravity, to equipment that is paving the way toward servicing and refueling satellites while they’re in orbit will be on board.

NASA to use Super Low Temperatures to slow Atoms for observation on International Space Station

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – This summer, an ice chest-sized box will fly to the International Space Station, where it will create the coolest spot in the universe.

Inside that box, lasers, a vacuum chamber and an electromagnetic “knife” will be used to cancel out the energy of gas particles, slowing them until they’re almost motionless. This suite of instruments is called the Cold Atom Laboratory (CAL), and was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California. CAL is in the final stages of assembly at JPL, ahead of a ride to space this August on SpaceX CRS-12.

Its instruments are designed to freeze gas atoms to a mere billionth of a degree above absolute zero. That’s more than 100 million times colder than the depths of space.

NASA’s Earth Science continues research from International Space Station

 

Written by Samson Reiny
NASA Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow.

Two new instruments are scheduled to make their way to the station on the SpaceX Dragon capsule.

The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the condition of the ozone layer, which covers an area in the stratosphere 10 to 30 miles (16 to 48 kilometers) above Earth and protects the planet from the sun’s harmful ultraviolet radiation.

NASA to send Stratospheric Aerosol and Gas Experiment III (SAGE III) to International Space Station

 

Written by Eric Gillard
NASA Langley Research Center

NASA - National Aeronautics and Space AdministrationHampton, VA – Brooke Thornton has devoted eight years to a project that aims to check on the atmospheric health of the Earth. Needless to say, when NASA’s Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III on ISS) launches, she’ll be among the many cheering and working for its success in space.

“After seeing SAGE III mature from concept, to development, to assembly and testing, and preparing for mission ops … I’m excited to see it launch so we get the science we have worked so hard for,” she said.

NASA looks at the Super Bowl – 5 Things Football has in Common with Space

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As Super Bowl LI in Houston Texas approaches and players, coaches and a host of personnel behind the scenes prepare for the big game in Space City, NASA remains on the cutting edge of human space exploration, setting its sights on the journey to Mars.

A football player’s journey to the end zone, though, has a lot more in common to space exploration than one might think.

Here are five similarities.

NASA Astronauts complete Second Spacewalk of the year on International Space Station

 

Written by Mark Garcia
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Expedition 50 Commander Shane Kimbrough and Flight Engineer Thomas Pesquet concluded their spacewalk at 12:20pm EST. During the nearly six hour spacewalk, the two NASA astronauts successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station.

The new lithium-ion batteries and adapter plates replace the nickel-hydrogen batteries currently used on the station to store electrical energy generated by the station’s solar arrays.
