NASA to Preview Pair of Upcoming US Spacewalks, Provide Live Coverage

Two NASA astronauts are scheduled to venture outside the International Space Station for a pair of six-and-a-half-hour spacewalks May 16 and June 14

NASA’s IMERG shows devastating rainfall over East Africa

Heavy seasonal rainfall has recently caused flooding in Kenya and NASA analyzed and estimated the total rainfall using data from a suite of satellites and gauges. The heavy rainfall has resulted in the displacement of over 244,000 people. This deluge follows the severe drought that afflicted East Africa in 2017. The estimated death toll from flooding and mudslides has recently been increased to about 100…

May the forest be with you: GEDI moves toward launch to...

A first-of-its-kind laser instrument designed to map the world's forests in 3-D is moving toward an earlier launch to the International Space Station than previously expected. The Global Ecosystem Dynamics Investigation - or GEDI, pronounced like "Jedi," of Star Wars fame - instrument is undergoing final integration and testing this spring and summer at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The instrument is…

Burst of newborn stars in young star cluster puzzles astronomers

IMAGE: Each point represents one star. Black points are normal stars. Blue and red points represent blue straggler stars belonging to two clear sequences. The blue solid and blue dashed lines... view more  Credit: NAOC Since the limited amount of gas survived from the first bulk star forming process will be quickly expelled within several million years, star clusters have long been thought of as "infertile"…

Prototype camera set for integration into novel gamma-ray telescope

X-ray navigation considered for possible CubeSat mission

IMAGE: Engineers Luke Winternitz (left), Jason Mitchell (right) and their team developed a unique tabletop device -- aptly described as a 'pulsar on a table' -- to simulate rapid-fire X-ray pulsations... view more  Credit: Credits: NASA/P. Izzo Now that NASA has shown the viability of autonomous X-ray navigation in space, a team led by the Smithsonian Astrophysical Observatory plans to include the technology on a proposed…

NASA Brings the International Space Station Experience to Salt Lake City

NASA is traveling to the Salt Lake City area May 15-17 to share the accomplishments, promise and opportunities for research aboard the International Space Station.

NASA finds Tropical Cyclone Flamboyan in a southeastern stretch

IMAGE: NASA's Aqua satellite provided a visible image of Tropical Cyclone Flamboyan on May 2 at 3:50 a.m. EDT (0750 UTC). The storm is devoid of rainfall with the exception of... view more  Credit: NASA/NRL Strong vertical wind shear had taken its toll on Tropical Cyclone Flamboyan when NASA's Aqua satellite passed over the Southern Indian Ocean. Flamboyan, now a subtropical cyclone, had been stretched out…
