Testing instruments for Artemis astronauts

NASA's Artemis program will establish a sustainable presence at the Moon as we prepare to venture on to Mars. To empower the success of these missions, terrestrial engineers must furnish astronauts with the tools they need ...

Spacecraft reveal new details of magnetic reconnection

The space environment around Earth is characterized by interactions between Earth's magnetic field and nearby plasma. A key physical process in these interactions is magnetic reconnection, in which two adjacent field lines ...

Astronauts test virus-fighting surface coating

Astronauts aboard the International Space Station (ISS) are conducting experiments with an antimicrobial surface coating designed to fight the spread of bacteria and viruses.

MESSENGER saw a meteoroid strike Mercury

Telescopes have captured meteoroids hitting the Moon and several spacecraft imaged Comet Shoemaker–Levy 9 smacking into Jupiter in 1994. But impacts as they happen on another rocky world have never been observed.

Device mimics life's first steps in outer space

A device developed by scientists at the CY Cergy Paris University and Paris Observatory promises insight into how the building blocks of life form in outer space.

Fertilizer made from urine could enable space agriculture

In extreme environments, even the most ordinary tasks can seem like unsurmountable challenges. Because of such difficulties, humanity has, for the most part, settled on grounds that were favorable for harvesting crops, herding ...

Giant particle accelerator in the sky

The Earth's magnetic field traps high-energy particles. When the first satellites were launched into space, scientists led by James Van Allen unexpectedly discovered the high-energy particle radiation regions, which were ...
