Readying spacecraft to surf Venus’ atmosphere
Thursday, 28 July 2022 06:30
ESA’s EnVision mission to Venus will perform optical, spectral and radar mapping of Earth’s sister planet. But before getting down to work the van-sized spacecraft needs to ‘aerobrake’ – lowering its orbit with thousands of passages through the planet’s hot, thick atmosphere for up to two years. A unique ESA facility is currently testing candidate spacecraft materials to check they can safely withstand this challenging process of atmospheric surfing.

A spacewalk full of firsts UCLA scientists discover places on the moon where it's always 'sweater weather'
Wednesday, 27 July 2022 09:43
Future human explorers on the moon might have 99 problems but staying warm or cool won't be one. A team led by planetary scientists at UCLA has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit.
The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habi Making Muons for Scientific Discovery, National Security

Wednesday, 27 July 2022 09:43
Small drones delivering packages, air taxis carrying passengers, or air ambulance providing lifesaving transportation - these are just some of the concepts NASA's Advanced Air Mobility (AAM) mission is helping get into our skies. For these aircraft to safely operate, cities, suburbs, and rural areas will need new or enhanced infrastructure.
Imagine a network of routes where new aircraft wo
