Space isn't empty. Space is considered an environment — an extreme environment, filled with entities that can be harmful to spacecraft. In space, there are several environmental threats that can harm materials used to create spacecraft. These threats include ultraviolet rays and x-rays from the sun; solar wind particle radiation; thermal cycling (hot and cold cycles)

More than 30 years after they left Earth, NASA's twin Voyager probes are now at the edge of the solar system. Not only that, they're still working. And with each passing day they are beaming back a message that, to scientists, is both unsettling and thrilling. The message is, "Expect the unexpected." "It's uncanny," says Ed Stone of Caltech, Voyager Project Scientis

Here are five facts about NASA's twin Voyager 1 and 2 spacecraft, the longest continuously-operating spacecraft in deep space. The Voyagers were built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., which continues to operate both spacecraft. Long-Distance Space RunnersVoyager 2 launched on Aug. 20, 1977, and Voyager 1 launched about two weeks later, on Sept

Students and educators nationwide will have the opportunity to interact with NASA engineers and scientists through two newly developed NASA flight initiatives. The programs, developed at NASA's Wallops Flight Facility in Virginia, are designed to give students and educators hands-on flight experiences using NASA sounding rockets and scientific balloons. The Wallops R

To celebrate the 21st anniversary of the Hubble Space Telescope's deployment into space, astronomers at the Space Telescope Science Institute in Baltimore, Md., pointed Hubble's eye at an especially photogenic pair of interacting galaxies called Arp 273. "For 21 years, Hubble has profoundly changed our view of the universe, allowing us to see deep into the past while

NASA is partnering with other federal agencies to fund new research and applications efforts that will bring the global view of climate from space down to Earth to benefit wildlife and key ecosystems. NASA, the U.S. Geological Survey, National Park Service, U.S. Fish and Wildlife Service and Smithsonian Institution will provide $18 million for 15 new research project

NASA scientists conducting an airborne campaign right now in the Arctic to monitor changes in sea ice and ice sheet thickness have a new tool. A second aircraft -- the King Air B200 - arrived in Kangerlussuaq, Greenland, carrying an instrument that maps the icy surface from more than five miles (8 km) above, providing yet another perspective of Earth's changing polar

PSLV-C16, is the eighteenth flight of ISRO's Polar Satellite Launch Vehicle, PSLV. In this flight, the standard version of PSLV with six solid strap-on motors is used. PSLV-C16 will place three satellites with a total payload mass of 1404 kg - RESOURCESAT-2 weighing 1206 kg, the Indo-Russian YOUTHSAT weighing 92 kg and Singapore's X-SAT weighing 106 kg – into an 822

High up in the sky near the poles some 50 miles above the ground, silvery blue clouds sometimes appear, shining brightly in the night. First noticed in 1885, these clouds are known as noctilucent, or "night shining," clouds. Their discovery spawned over a century of research into what conditions causes them to form and vary – questions that still tantalize scientists

To celebrate Earth Day 2011, the Education Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is hosting a live Web video chat where your students can ask a NASA/JPL scientist questions emailed in advance.  Questions should be on the topic of Earth science. Our chat is best suited for students and afterschool groups in grades 4 - 6. Our guest

A rotating device developed by NASA inventors to grow better living tissue specimens was inducted into the Space Technology Hall of Fame Thursday, April 14. The Space Foundation honored the NASA team who created the device, which promises help for several diseases, during a ceremony at the 27th National Space Symposium in Colorado Springs, Colo. Developed in 19

The first six of 18 segments that will form NASA's James Webb Space Telescope’s primary mirror for space observations will begin final round-the-clock cryogenic testing this week. These tests will confirm the mirrors will respond as expected to the extreme temperatures of space prior to integration into the telescope's permanent housing structure. The X-ray and Cryog

After 30 years of spaceflight, more than 130 missions, and numerous science and technology firsts, NASA's space shuttle fleet will retire and be on display at institutions across the country to inspire the next generation of explorers and engineers. NASA Administrator Charles Bolden on Tuesday announced the facilities where four shuttle orbiters will be displayed per

Since 1981, NASA space shuttles have been rocketing from the Florida coast into Earth orbit. The five orbiters — Columbia, Challenger, Discovery, Atlantis and Endeavour — have flown more than 130 times, carrying over 350 people into space and travelling more than half a billion miles, more than enough to reach Jupiter. Designed to return to Earth and land like a gian
