Watch Earth roll by through the perspective of ESA astronaut Alexander Gerst in this six-minute timelapse video from space. Combining 12 500 images taken by Alexander during his six-month Blue Dot mission on the International Space Station this Ultra High Definition video shows the best our beautiful planet has to offer.
Marvel at the auroras, sunrises, clouds, stars, oceans, the Milky Way, the International Space Station, lightning, cities at night, spacecraft and the thin band of atmosphere that protects us from space.
On November 26, 2011, the Mars Science Laboratory began a 253-day, 560-million-kilometer journey to deliver the Curiosity rover to the Red Planet. En route, the Southwest Research Institute-led Radiation Assessment Detector (RAD) made detailed measurements of the energetic particle radiation environment inside the spacecraft, providing important insights for future human missions to Mars.
“In terms of accumulated dose, it’s like getting a whole-body CT scan once every five or six days,” said Dr. Cary Zeitlin, a principal scientist in SwRI’s Space Science and Engineering Division and lead author of Measurements of Energetic Particle Radiation in Transit to Mars on the Mars Science Laboratory, scheduled for publication in the journal Science on May 31.
“Understanding the radiation environment inside a spacecraft carrying humans to Mars or other deep space destinations is critical for planning future crewed missions,” Zeitlin said. “Based on RAD measurements, unless propulsion systems advance rapidly, a large share of mission radiation exposure will be during outbound and return travel, when the spacecraft and its inhabitants will be exposed to the radiation environment in interplanetary space, shielded only by the spacecraft itself.”
Three new crew members are on their way to the International Space Station. NASA Flight Engineer Sunita Williams, Russian Soyuz Commander Yuri Malenchenko and Japan Aerospace Exploration Agency Flight Engineer Akihiko Hoshide blasted off from the Baikonur Cosmodrome in Kazakhstan at 10:40 p.m. EDT Saturday, July 14 (8:40 a.m. Baikonur time July 15).
Williams, Malenchenko and Hoshide are scheduled to dock their Soyuz TMA-05M spacecraft to the Rassvet module of the station at 12:52 a.m. EDT Tuesday, July 17. They will join Expedition 32 Commander Gennady Padalka of the Russian Federal Space Agency and Flight Engineers Joe Acaba of NASA and Sergei Revin of Russia, who have been aboard the orbiting laboratory since May 17.
The six crew members will work together for about two months. Acaba, Padalka and Revin are scheduled to return to Earth Sept. 17. Before they depart, Padalka will hand over command of the station and Expedition 33 to Williams. She, Malenchenko and Hoshide will return home in mid-November.
NASA has selected six proposals to improve the affordability, reliability and performance of an advanced booster for the Space Launch System (SLS). The awardees will develop engineering demonstrations and risk reduction concepts for SLS, a heavy-lift rocket that will provide an entirely new capability for human exploration beyond low Earth orbit.
“The initial SLS heavy-lift rocket begins with the proven hardware, technology and capabilities we have today and will evolve over time to a more capable launch vehicle through competitive opportunities,” said William Gerstenmaier, associate administrator for the Human Exploration Operations Mission Directorate at NASA Headquarters in Washington. “While the SLS team is making swift progress on the initial configuration and building a solid baseline, we also are looking ahead to enhance and upgrade future configurations of the heavy lift vehicle. We want to build a system that will be upgradable and used for decades.”
Designed to be flexible for launching spacecraft, including NASA’s Orion multipurpose vehicle, for crew and cargo missions SLS will enable NASA to meet the president’s goal of sending humans to an asteroid by 2025 and to Mars in the 2030s. The initial SLS configuration will use two five-segment solid rocket boosters similar to the solid rocket boosters that helped power the space shuttle to orbit. The evolved SLS vehicle will require an advanced booster with significant increase in thrust from any existing U.S. liquid or solid boosters.
NASA partner Space Exploration Technologies (SpaceX) has completed an important design review of the crewed version of its Dragon spacecraft. The concept baseline review presented NASA with the primary and secondary design elements of its Dragon capsule designed to carry astronauts into low Earth orbit, including the International Space Station.
SpaceX is one of several companies working to develop crew transportation capabilities under the Commercial Crew Development Round 2 (CCDev2) agreement with NASA’s Commercial Crew Program (CCP). Through CCDev2, NASA is helping the private sector develop and test new spacecraft and rockets with the goal of making commercial human spaceflight services available to commercial and government customers.
In the June 14 review conducted at the company’s headquarters in Hawthorne, Calif., SpaceX provided details about each phase of a potential crewed mission. This included how the company plans to modify its launch pads to support such missions, Dragon’s docking capabilities, the weight and power requirements for the spacecraft, and prospective ground landing sites and techniques. The company also outlined crew living arrangements, such as environmental control and life support equipment, displays and controls.
NASA invites its social media followers to a two-day NASA Social Aug. 2-3 to celebrate Kennedy Space Center’s 50 years of human spaceflight. NASA Socials are in-person meetings with people who engage with the agency through Twitter, Facebook, Google+ and other social networks.
Participants will receive a unique perspective into Kennedy’s 50 years of launching humans and machines into low Earth orbit and to other planets. They will be treated to speakers from Kennedy’s past, present and future, and tour the historical launch pads of NASA’s early days through the present-day facilities that supported the Space Shuttle Program and Kennedy’s transition to the future.
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.”
