1,935.3 grams of lunar samples retrieved by Chang’e-6; China welcomes intl data sharing but urges US to remove obstacles
2024-08-18 15:19:52
The first batch of soils and rocks from the Moon's far side ever obtained by mankind weighs a total of 1,935.3 grams, which was brought safely back by China's Chang'e-6 mission, according to an announcement by the China National Space Administration (CNSA) on Friday during a handover ceremony in Beijing. China welcomes the sharing of data with scientists around the world and maintains an open attitude toward cooperating with the US, CNSA officials said, but the US should remove obstacles including the Wolf Amendment that hinders such collaboration.
Novel electrolyte design shows promise for longer-lasting lithium-metal batteries
2024-08-18 13:26:48
Lithium-metal batteries could exhibit significantly higher energy densities than lithium-ion batteries, which are the primary battery technology on the market today. Yet lithium-metal cells also typically have significant limitations, the most notable of which is a short lifespan.
