Nasa removes US astronaut from ISS mission

Science
The US astronaut Jeanette Epps has been removed from her upcoming mission to the International Space Station (ISS) just months before launch.Dr Epps was to have been the first African-American astronaut assigned to the space station crew.She would have flown aboard a Russian Soyuz flight in June but is being replaced by another astronaut.Nasa has not given a reason for withdrawing her but says she will be considered for future missions.Jeanette Epps, born in Syracuse, completed a doctorate in aerospace engineering in 2000. After graduating, she worked in a laboratory for two years before being recruited by the Central Intelligence Agency (CIA).She worked as a technical intelligence officer for seven years before being selected as a member of Nasa's 2009 astronaut class. Her time with the C...

NASA bumps astronaut off space station flight in rare move

Technology
NASA has bumped an astronaut off an upcoming spaceflight, a rare move for the space agency so close to launch. Astronaut Jeanette Epps was supposed to rocket away in early June, and would have been the first African-American to live on the International Space Station. Late Thursday, NASA announced it was pulling Epps off the mission but didn't disclose why. Astronauts have been removed from missions in the past, mostly for health reasons. Epps, an engineer, will be considered for future space missions, according to NASA. She's been replaced by her backup, Serena Aunon-Chancellor, a doctor. Both were chosen as astronauts in 2009. Epps is returning to Houston from Russia, where she'd been training to fly to the space station with a German and Russian. NASA spokeswoman Brandi Dean said Friday...

NASA: 2017 was second warmest year since 1880

Science
Jan. 18 (UPI) -- NASA temperature measurements suggest 2017 was the second warmest year since detailed record keeping began in 1880. NOAA data suggests last year was the third warmest in modern history."The minor difference in rankings is due to the different methods used by the two agencies to analyze global temperatures, although over the long-term the agencies' records remain in strong agreement," NOAA announced in a news release.When mitigating the impacts of the El Nino pattern in the Pacific, the data showed 2017 was the warmest year on record.According to scientists at NASA's Goddard Institute for Space Studies in New York, the average global temperature in 2017 was 1.62 degrees Fahrenheit warmer than the average temperature between 1951 and 1980. Only 2016 was hotter, according to ...

NASA satellite spots shattered iceberg beneath the Antarctica's midnight sun

Science
Dec. 29 (UPI) -- A newly released NASA image showcases the fragmented state of iceberg B-44, glistening in the midnight sun of Antarctica.B-44 is the berg that calved from Pine Island Glacier in September. Pine Island Glacier is one of the West Antarctic Ice Sheet's main outflows. B-44 was the second major fragment to separate from the glacier in the last several years. The first calving occurred in 2015.Analysis suggests the ice sheet and its glaciers are breaking apart from the inside out as warming ocean water weakens the coastal ice shelf from beneath.Scientists believe an unusually warm pocket of water also explains the rapid breakup of B-44, which shattered into more than 20 fragments shortly after its separation from the glacier. The warm water, known as a polyna, has prevented the ...

NASA considering missions to comet and Saturn's Moon Titan

Science
Dec. 20 (UPI) -- NASA is considering possible missions a comet and Titan, Saturn's largest moon. The space agency selected the two concept finalists on Wednesday.The selected missions were two of 12 proposals submitted as part NASA's New Frontiers program."This is a giant leap forward in developing our next bold mission of science discovery," Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate in Washington, said in a news release. "These are tantalizing investigations that seek to answer some of the biggest questions in our solar system today."The Comet Astrobiology Exploration Sample Return mission, or CAESAR concept, proposes a NASA-funded visit to 67P/Churyumov-Gerasimenko, the comet visited by the European Space Agency's Rosetta spacecraft and Philae lande...
