Northern Ireland needs 'courage and leadership' to tackle climate change

The Orionid meteor shower, which is capable of producing bright fireball meteors, is set to peak in UK skies this week. While it has been active for most of October, the celestial spectacle will be at its best in the early hours of October 22. Clear skies permitting, skygazers could be able to spot as many as 10-20 meteors per hour.

Human activities have become intertwined with how water is distributed across the continents. A new study brings their effects into sharper focus. Humans are exerting increasing influence over how water moves through lakes, rivers, soil, and the subsurface, and a new NASA study shows where those effects are greatest. Using more than two decades of satellite measurements of subtle changes in Earth’s gravity, the researchers sharpened the picture of how—and why—terrestrial water storage has changed.

Rockets vibrate, shake, and flex intensely as they climb into space, and spacecraft packed with delicate scientific instruments must survive those forces. Before any rocket leaves the ground, NASA engineers work to predict how those stresses will affect every part of a spacecraft. To do that, engineers in the Dynamic Environments Group with NASA’s Launch […]

The four crew members in NASA’s simulated Mars mission have spent the past year living and working in isolation in a confined habitat at NASA’s Johnson Space Center in Houston.
