A-81 Reaches South Georgia

The Antarctic iceberg made a relatively quick exit from the Weddell Sea, only to slow at the edge of a remote island’s underwater shelf.

Some Antarctic icebergs linger close to home for decades, running aground near the ice shelves that spawned them or circling partway around the continent on coastal currents. Others, like Iceberg A-81, make a faster exit, heading north out of the Weddell Sea along a route well-traveled by the region’s bergs.

NASA’s Perseverance Views Dust at Neretva Vallis

This 360-degree look at Neretva Vallis within Mars’ Jezero Crater was stitched together using 217 images acquired by the rover’s Mastcam-Z on May 20, 2024, the 1,155th Martian day, or sol, of the mission. While it is a wind-swept dusty vista today, billions of years ago it was home to a river channel that fed fresh water into Jezero Crater. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.

NEO Surveyor’s Sunshade Gets Inspected

The large sunshade of NASA’s Near-Earth Object (NEO) Surveyor is mounted on an assembly ring during inspections in a clean room at BAE Systems Space & Mission Systems in Boulder, Colorado, in July 2026. Built by Applied Aerospace in Stockton, California, the sunshade structure was outfitted with its solar cells by SolAero Technologies in Albuquerque, New Mexico, in January. Environmental testing of the sunshade and solar array was completed at a commercial thermal vacuum testing facility in El Segundo, California, in March and it was delivered to BAE Systems Space & Mission Systems ahead of schedule in May.
