Arc Jet Complex Providing ground-based hyperthermal environments in support of the Nation?s Research & Development activities in Thermal Protection Materials, Vehicle Structures, Aerothermodynamics, and Hypersonic Entry. https://www.facebook.com/nasaames/videos/10154330812546394/ Benefit Innovative thermal protection materials and systems will be required to support NASA Exploration. Project missions, in particular crewed Moon or Mars return missions, will involve high velocity aerocapture or direct entry at Earth. These high stress missions will induce heating environments too severe for existing reusable Thermal Protection Systems (TPS). Qualifying a new TPS material for a crewed mission requires extensive testing to explore the limits of material performance, to validate reliability and repeatability of performance, to investigate the effects of material damage, and to develop a full database of material properties. Arc plasma facilities, operated by the Thermophysics Facilities Branch at NASA Ames, are critical to such a process, and to any other TPS developments required for Exploration missions, by providing the only ground-based simulation of flight entry conditions.

Comet C/2024 E1 Taken by Ian Griffin on February 5, 2026 @ Middlemarch, New Zealand Details: A lovely comet is gracing the southern sky. This evening I managed to get a set of 26x90 second exposures of it before moonlight interfered. The comet is sweeping through the southern constellation of Grus, which contains many beautiful galaxies. Photographer's website: https://www.instagram.com/portobellopictures/

Giza the black leopard. A British wildlife photographer has captured stunning images of a rare black leopard. Andy Rouse was guiding in Kenya when he spotted the distinctive big cat Giza, a mother living in the Laikipia region. He said: "This is seven-year-old black female leopard called Giza. She's very famous as she's so bold and beautiful, and lives in the Laikipia Wildlife Conservancy. It's been an ambition of mine for several years to photograph her for my forthcoming leopard project, and wow what an experience it was. She took my breath away the first time I saw her, probably the most beautiful cat I have ever seen and I have seen a lot."

TUNSTALL, ENGLAND - JANUARY 24: In this aerial view people view a decommissioned cold war nuclear observation post has fallen on to the beach after clinging perilously to the cliff face for the last month on January 24, 2026 in Tunstall, England. The decommissioned bunker, known as Tunstall ROC (Royal Observer Corps), is believed to have been built in 1959 as a nuclear monitoring post during the Cold War. Rapid erosion along the East Yorkshire coastline left it exposed and caused it to collapse. (Photo by Christopher Furlong/Getty Images)
