Searching for Sand Transport

Pasadena CA (JPL) Jul 08, 2022
Perseverance is currently stopped for sampling at Skinner Ridge rock. Sampling activities constitute an important aspect of Perseverance's mission, and the rover's strategic path is developed around sampling stops. During these stops, the rover must remain stationary for at least twelve sols in order to conduct proximity science and activities related to abrasion and coring. But being parked in

After analyzing data gathered when NASA's OSIRIS-REx spacecraft collected a sample from asteroid Bennu in October 2020, scientists have learned something astonishing: The spacecraft would have sunk into Bennu had it not fired its thrusters to back away immediately after it grabbed dust and rock from the asteroid's surface. It turns out that the particles making up Bennu's exterior are so l

Around 4.4 billion years ago, the early solar system resembled a game of space rock dodgeball, as massive asteroids and comets, and, later, smaller rocks and galactic debris pummeled the moon and other infant terrestrial bodies. This period ended around 3.8 billion years ago. On the moon, this tumultuous time left behind a heavily cratered face, and a cracked and porous crust. Now MIT scie
NASA mirrors on ESA pathfinder to enhance lunar navigation

NASA will supply the upcoming European Space Agency (ESA) Lunar Pathfinder satellite with an array of laser retroreflectors, mirrored devices that reflect light back at its source. The retroreflectors will validate navigation capabilities that will be critical to the Artemis missions and future lunar exploration.

Deployment test of James Webb Space Telescope's primary mirror

The NASA/ESA/CSA James Webb Space Telescope will soon reveal unprecedented and detailed views of the Universe, with the upcoming release of its first full-colour images and spectroscopic data.

From laser beams to galactic tow-truck services, start-ups in Japan are trying to imagine ways to deal space debris
From laser beams to galactic tow-truck services, start-ups in Japan are trying to imagine ways to deal space debris.

From laser beams and wooden satellites to galactic tow-truck services, start-ups in Japan are trying to imagine ways to deal with a growing environmental problem: space debris.

Junk like used satellites, parts of rockets and wreckage from collisions has been piling up since the space age began, with the problem accelerating in recent decades.

"We're entering an era when many satellites will be launched one after another. Space will become more and more crowded," said Miki Ito, general manager at Astroscale, a company dedicated to "space sustainability".

"There are simulations suggesting space won't be usable if we go on like this," she told AFP. "So we must improve the celestial environment before it's too late."

The European Space Agency (ESA) estimates that around one million pieces of debris larger than a centimeter—big enough to "disable a spacecraft"—are in Earth's orbit.

Big data has become a big challenge for space scientists analyzing vast datasets from increasingly powerful space instrumentation. To address this, a Southwest Research Institute team has developed a machine learning tool to efficiently label large, complex datasets to allow deep learning models to sift through and identify potentially hazardous solar events. The new labeling tool can be applied
