NASA's Juno gives aerial views of mountain and lava lake on Io

Scientists on NASA's Juno mission to Jupiter have transformed data collected during two recent flybys of Io into animations that highlight two of the Jovian moon's most dramatic features: a mountain and an almost glass-smooth ...

Hubble goes hunting for small main belt asteroids

Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don't stop to be photographed as they zip along ...

Are Titan's dunes made of comet dust?

A new theory suggests that Titan's majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan's dunes was locally made, through erosion or condensed from atmospheric ...

NASA chief warns of Chinese military presence in space

China is bolstering its space capabilities and is using its civilian program to mask its military objectives, the head of the US space agency NASA said Wednesday, warning that Washington must remain vigilant.

'Tube map' around planets and moons made possible by knot theory

Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste ...

NASA observations find what helps heat roots of 'moss' on sun

Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified ...

NASA to hoist its sail: Solar sail mission gets ready for launch

A NASA mission testing a new way of navigating our solar system is ready to hoist its sail into space—not to catch the wind, but the propulsive power of sunlight. The Advanced Composite Solar Sail System is targeting launch ...

NASA's Roman space telescope's 'eyes' pass first vision test

Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics ...

Astronauts to patch up NASA's NICER telescope

NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit ...
