Launching Lucy, NASA’s First Mission to the Trojan Asteroids

Posted by in categories: evolution, media & arts, space

On Oct. 16 2021, our Lucy spacecraft will begin its journey to visit a record-breaking number of asteroids. The 12-year mission starts from NASA’s Kennedy Space Center where it’ll launch aboard a United Launch Alliance Atlas V 401 rocket. From there, Lucy will be the first spacecraft to visit a record number of destinations in independent orbits around the sun – one main belt asteroid and seven of Jupiter’s Trojan Asteroids. Like the mission’s namesake – the fossilized human ancestor, “Lucy,” whose skeleton provided unique insight into humanity’s evolution – Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system.

Lucy’s first launch attempt in its 21-day launch window is scheduled for 5:34 a.m. EDT on Oct. 16. Launch coverage starts at 5 a.m. EDT on NASA TV, the NASA app, and @NASA social media. Be a part of Lucy’s historic launch day by using the hashtag #LucyMission!

Researchers transform water into a metallic material that conducts electricity

Posted by in categories: materials, space

It is a well-known fact that pure, distilled water is an almost perfect insulator and does not conduct electricity. It consists of H2O molecules that are loosely linked to one another via hydrogen bonds. However, any impurities, like salts, in the water enable it to conduct electricity. To create a conduction band with freely moving electrons, water would have to be pressurized to such an extent that the orbitals of the outer electrons overlap, something that only exists deep inside of large planets such as Jupiter.

Now, a team of researchers from 11 institutions around the world have used a completely different approach to create metallic water for the first time. They have achieved that feat by forming a thin layer of gold-colored metallic water on the outside of a droplet of liquid metal and documented this phase transition at the BESSY II facility in Berlin.

The key to the breakthrough was to pair the water with alkali metals, which release their outer electron very easily.
