NASA astronaut Mark Polansky has left the agency. His last day with NASA was June 30.

Polansky is a veteran of three space shuttle missions. He flew as a pilot on the STS-98 mission in 2001 and served as commander for STS-116 in 2006 and STS-127 in 2009. Polansky ends his NASA career with more than 41 days in space.

“Mark is a remarkably talented individual,” said Peggy Whitson, chief of the Astronaut Office. “His skills as an aviator coupled with his engineering expertise were a valuable contribution to our team. We wish him well in his future endeavors.”

NASA Astronaut Stephen K. Robinson Leaves Agency


NASA astronaut Stephen Robinson has left the space agency. Robinson ends his 36-year NASA career as a veteran of three spacewalks with more than 48 days of spaceflight experience. Robinson will become a professor at the University of California at Davis in the fall of 2012. His last day at NASA was June 30.

Robinson began work with NASA as a cooperative education student in 1975 at the agency’s Ames Research Center at Moffett Field, Calif. He was selected for the astronaut corps in 1995. Robinson served as a mission specialist on four spaceflights, including space shuttle missions STS-85 in 1997, STS-95 in 1998, STS-114 in 2005 and STS-130 in 2010.

Prediction System To Protect Astronauts From Solar Storms

June 30, 2012 1 comment

With the impending solar maximum expected to bring heightened rates of flares and coronal mass ejections (CMEs), putting at risk an ever-increasing human presence in space, Oh et al. designed and assessed a prediction system to keep astronauts safe from these solar storms. During a solar flare or CME, particles from the Sun can be accelerated to very high energies-in some cases travelling near the speed of light. Protons with energies surpassing 100 megaelectron volts essentially sandblast everything in their path. Though people on Earth are protected by the planet’s magnetic field and thick atmosphere, astronauts in spacecraft beyond low-Earth orbit, or people at high altitudes near the poles, can be exposed to this increased radiation. This can potentially cause radiation sickness, with symptoms such as fever and vomiting.

NASA Commercial Crew Partner Boeing Meets Software Milestone


CAPE CANAVERAL, Fla. — The Boeing Company has successfully completed a new milestone in the development of software that will operate its Crew Space Transportation (CST) spacecraft. The company is one of NASA’s partners developing commercial crew transportation capabilities to ferry U.S. astronauts to and from low Earth orbit and the International Space Station.

With the Preliminary Design Review (PDR) of its software on May 18, the company now has completed more than 40 milestones under partnerships supporting NASA’s Commercial Crew Program (CCP).

NASA Seeks Hosts for Space Station Interactive Education Events


NASA is seeking formal and informal education organizations to host live in-flight interactive conversations between the next generation of explorers and astronauts aboard the International Space Station (ISS).

Comprehensive proposals are being accepted for missions scheduled between September 2012 and March 2013. The deadline to submit is Friday, June 1, 2012.

During ISS Expeditions 33 and 34, NASA crew members Sunita Williams, Kevin Ford and Thomas Marshburn will participate in 20-minute question-and-answer sessions with students who will learn what it is like to live and work in space. While participants see and hear the crew members live from space, the crew does not see the audience.

U.S. education organizations including school districts, museums, science centers, national and regional education organizations and local, state and federal government agencies are eligible to participate. Organizations may apply individually or work together. NASA provides this opportunity at no charge to the host institution and will work with the organization to plan the event.

Record-Setting Astronaut Lopez-Alegria Departs NASA

March 13, 2012 Leave a comment

Michael Lopez-Alegria, NASA’s most experienced spacewalker and the American holding the record for the single longest spaceflight mission, has left the agency.

Lopez-Alegria flew on four missions and performed 10 spacewalks during his career. He most recently served in the Flight Crew Operations Directorate at NASA’s Johnson Space Center in Houston as assistant director for the International Space Station (ISS).

“Mike has faithfully served the Flight Crew Operations Directorate for many years,” said Janet Kavandi, director of Flight Crew Operations at Johnson. “His unique background and diplomatic skills have made him an outstanding FCOD assistant director for space station and lead for the Multilateral Crew Operations Panel. Mike’s tireless dedication to the safety and well-being of space station crews is well known. We will miss him and wish him well in his future endeavors.”
