NASA has delayed the undocking of a Crew Dragon spacecraft from the International Space Station by a day because of high winds at splashdown locations in the Gulf of Mexico, a move that won’t affect the launch of the next crew to the station.

A group of astronomers, led by scientists from the Max Planck Institute for Astronomy, propose and have tested a mechanism that explains most of the properties observed in dispersing planet-forming disks around newborn stars for the first time.

After our short bump on Tuesday, Curiosity has reached a new potential drill location. When we first arrived at the clay-sulfate transition, the science team decided on a strategy to drill every ~25 m in elevation gain.
This allows us to systematically document any changes in the composition of the terrain while being reasonable with our limited rover resources. The terrain is beginning t

Precise detection of magnetic fields is important for applications that range from magnetic brain imaging, to detection of sunken ships, to exploration of the solar system. For many of these applications, the most sensitive magnetic-field measuring instruments (magnetometers) are "optically-pumped magnetometers," which use laser light to probe magnetically-sensitive atoms.

Because of their high strength and light weight, carbon-fiber-based composite materials are gradually replacing metals for advancing all kinds of products and applications, from airplanes to wind turbines to golf clubs. But there's a trade-off. Once damaged or compromised, the most commonly-used carbon fiber materials are nearly impossible to repair or recycle.
