NASA’s Fermi Gamma-Ray Space Telescope looks for Dark Matter

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping scientists rule out some of the many theoretical possibilities.

Three studies published earlier this year, using six or more years of data from NASA’s Fermi Gamma-ray Space Telescope, have broadened the mission’s dark matter hunt using some novel approaches.

This image superimposes a photograph of the SMC with one half of a model of its dark matter (right of center). Lighter colors indicate greater density and show a strong concentration toward the galaxy's center. Ninety-five percent of the dark matter is contained within a circle tracing the outer edge of the model shown. (Dark matter, R.

NASA reports SpaceX spacecraft to deliver U.S. Astronaut to Internation Space Station

 

Written by Stephanie Martin
NASA’s Kennedy Space Center

NASA - National Aeronautics and Space AdministrationFlorida – NASA took another important step Friday in returning U.S. astronaut launches from U.S. soil with the order of a second post-certification mission from commercial provider SpaceX in Hawthorne, California. Commercial crew flights from Florida’s Space Coast to the International Space Station will restore America’s human spaceflight launch capability and increase the time U.S. crews can dedicate to scientific research, which is helping prepare astronauts for deep space missions, including the Journey to Mars.

“The order of a second crew rotation mission from SpaceX, paired with the two ordered from Boeing will help ensure reliable access to the station on American spacecraft and rockets,” said Kathy Lueders, manager of NASA’s Commercial Crew Program. “These systems will ensure reliable U.S. crew rotation services to the station, and will serve as a lifeboat for the space station for up to seven months.”

NASA takes it’s next steps towards on the Journey to Mars

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – July is always a good time to assess where U.S. human space exploration has been and where it’s going. This year, July 20th marks the 40th anniversary of Viking, which in 1976 became the first spacecraft to land on Mars.

And just seven years — to the day — before Viking’s amazing feat, humans first set foot on another world, when Neil Armstrong and Buzz Aldrin set the Apollo 11 lunar module Eagle down in the moon’s Sea of Tranquility on July 20th, 1969.

NASA Researchers study how Microgravity affects Tiny Organisms in Space

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On May 11th, a sealed capsule containing fungi and bacteria fell from the sky and splashed down in the Pacific Ocean. Microbiologist Kasthuri Venkateswaran could hardly wait to see what was inside it.

At NASA’s Jet Propulsion Laboratory in Pasadena, California, Venkateswaran, who goes by Venkat, studies microbial life — the wild world of organisms too small for us to see with our eyes. Among his many research endeavors, Venkat has leading roles on two microbial experiments that recently returned from the International Space Station.

NASA reports Astronaut Jeff Williams to be first human to enter Expandable Module deployed in Space

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – On Monday, June 6th, astronaut Jeff Williams will enter the first human-rated expandable module deployed in space, a technology demonstration to investigate the potential challenges and benefits of expandable habitats for deep space exploration and commercial low-Earth orbit applications.

Williams and the NASA and Bigelow Aerospace teams working at Mission Control Center at NASA’s Johnson Space Center in Houston expanded the Bigelow Expandable Activity Module (BEAM) by filling it with air during more than seven hours of operations Saturday, May 28th.

NASA’s BEAM module attached to International Space Station now Fully Expanded and Pressurized

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Pressurization of the Bigelow Expandable Activity Module (BEAM) began at 4:34pm EDT, and the eight tanks filled with air completed full pressurization of the module 10 minutes later at 4:44pm. BEAM’s pressure will be equalized with that of the International Space Station, where it will remain attached for a two-year test period.

The module measured just over 7 feet long and just under 7.75 feet in diameter in its packed configuration. BEAM now measures more than 13 feet long and about 10.5 feet in diameter to create 565 cubic feet of habitable volume. It weighs approximately 3,000 pounds.

The BEAM expansion took several hours today as astronaut Jeff Williams sent two dozen pulses of air into the expandable module. (NASA TV)

NASA will connect Bigelow Expandable Activity Module to International Space Station, Saturday

 

Written by Cheryl Warner
NASA’s Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The first human-rated expandable structure that may help inform the design of deep space habitats is set to be installed to the International Space Station Saturday, April 16th. NASA Television coverage of the installation will begin at 5:30am EDT.

The Bigelow Expandable Activity Module (BEAM) will be attached to the station’s Tranquility module over a period of about four hours. Controllers in mission control at NASA’s Johnson Space Center in Houston will remove BEAM from the unpressurized trunk of SpaceX’s Dragon spacecraft, using the robotic Canadarm2, and move it into position next to Tranquility’s aft assembly port.

NASA takes a look at Scott Kelly’s Year in Space

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Like all journeys off planet Earth, it started with a flash, and a roar.

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko blasted off from the Baikonur Cosmodrome in Kazakhstan on March 27th, 2015. With a successful landing 340 days later on March 1st, 2016, the pair completed one of the most ambitious missions in the history of the International Space Station and opened a new chapter in human exploration.

NASA says Machines of the future will Self Diagnosis themselves

 

NASA Headquarters

NASA Washington,D.C. – In the future, machines will monitor their own health and request help, themselves, when something’s wrong, predicts David Cirulli, engineering vice president and cofounder of CEMSol LLC.

“There’s going to be an integrated system-health engine as part of every system out there, and it will be able to interface with other systems and components,” says Cirulli. “That’s what’s missing today.” He compares the capability to how sick human patients can verbalize symptoms to a doctor, giving them the crucial information they need to diagnose a problem.

The IMS that CEMSol licensed from Ames Research Center to develop its ISHM software has also been applied to the Black Hawk helicopter engine. (U.S. Navy)

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA astronaut and Expedition 46 Commander Scott Kelly and his Russian counterpart Mikhail Kornienko returned to Earth Tuesday after a historic 340-day mission aboard the International Space Station. They landed in Kazakhstan at 11:26pm EST/10:26 CT (10:26am March 2nd Kazakhstan time).

Joining their return trip aboard a Soyuz TMA-18M spacecraft was Sergey Volkov, also of the Russian space agency Roscosmos, who arrived on the station September 4th, 2015. The crew touched down southeast of the remote town of Dzhezkazgan.
