Behind the scenes with MetOp-SG and Sentinel-5
Video:
00:01:45
Experience the preparation of the MetOp-SG-A1 satellite, hosting Copernicus Sentinel-5, scheduled for liftoff on an Ariane 6 rocket from Europe’s Spaceport in Kourou, French Guiana, on 13 August 2025 at 02:37 CEST (12 August 21:37 Kourou time). This timelapse video captures key stages from the encapsulation within the Ariane 6 fairing to the installation in the launch tower.
MetOp-SG-A1 is the first in a series of three successive pairs of satellites. The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more

Giant rogue planets could host scaled-down planetary systems
New findings from the University of St Andrews suggest that giant free-floating planets, unbound to any star, could form their own miniature planetary systems.
Using data from the James Webb Space Telescope (JWST), researchers examined eight isolated planetary-mass objects between five and ten times the mass of Jupiter. Although similar in size to gas giants, these bodies drift alone in sp What is NASA's Distributed Spacecraft Autonomy?
Astronauts living and working on the Moon and Mars will rely on satellites to provide services like navigation, weather, and communications relays. While managing complex missions, automating satellite communications will allow explorers to focus on critical tasks instead of manually operating satellites.
Long duration space missions will require teaming between systems on Earth and other AST SpaceMobile to Acquire International S-Band Spectrum Rights for Satellite Broadband Expansion
AST SpaceMobile (NASDAQ: ASTS) has reached an agreement to purchase global S-Band spectrum priority rights under the International Telecommunication Union, enhancing its ability to deliver space-based cellular broadband directly to smartphones for commercial and government use.
Chairman and CEO Abel Avellan said, "Our revolutionary satellites and proprietary ASICs were designed with S-Band Unique Martian sulfate points to recent thermal activity and mineral formation
New research led by the SETI Institute has identified an unusual iron sulfate on Mars that may represent a previously unknown mineral, offering new insights into the planet's thermal and geochemical history. The study, published in Nature Communications, reveals the presence of ferric hydroxysulfate, a mineral that likely formed through heating and oxidation of more common hydrated sulfates.
