Worms in space—the molecular muscle experiment

Thousands of worms are being flown to the International Space Station later this year for scientists to understand more about spaceflight-induced muscle loss—the first UK experiment to take place on the International Space ...

Cool ways of studying the cryosphere

One of the key elements of Earth's climate system is the cryosphere – the many forms of ice found on Earth. Two new NASA missions use different technologies to help scientists better understand how frozen water is affecting ...

Scientists sketch out the foundations of a colony on Mars

EPFL scientists have mapped out the steps required to build a self-sustaining research base on Mars that would be habitable for the long term. Their work can help researchers set priorities for space programs exploring Mars ...

SDO spots two lunar transits in space

On Sept. 9, 2018, NASA's Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens when a celestial body passes between a larger body and an observer. This first lunar ...

Image: Bright spots on Ceres

Bright surface features on the dwarf planet Ceres known as faculae were first discovered by NASA's Dawn spacecraft in 2015. This mosaic of one such feature, Cerealia Facula, combines images obtained from altitudes as low ...

The legacy of NASA's Dawn, near end of mission
