NASA officials announced Tuesday that they are seriously considering sending the full-scale engineering model of the Perseverance Mars rover to the Moon, equipping the vehicle with a nuclear power source to explore the south pole region. The car-sized rover, nicknamed “Promise” (also known as OPTIMISM), currently resides at NASA’s Jet Propulsion Laboratory in California where […]

!Sentinel-1 radar vision Sentinel-1A paved the way for Europe’s Copernicus Earth observation program. Credit: ESA The European Space Agency has officially ended operations for Sentinel-1A, the first satellite of the Copernicus program, after more than 12 years of service. The spacecraft’s operational duties ceased on June 29, 2026, nearly double its original 7-year design lifetime. […]

Startup Orbital Files FCC Plans for 100,000 Data Center Satellites A five-month-old startup named Orbital has filed an application with the Federal Communications Commission for permission to deploy up to 100,000 data center satellites in low Earth orbit, a proposal that would create the largest constellation ever filed by a single company. The application, submitted […]

Scientists Confirm Two Long Gamma-Ray Bursts Came from Collapsing Neutron Stars A team of researchers at Los Alamos National Laboratory has confirmed that two unusual long-duration gamma-ray bursts, GRB 211211A and GRB 230307A, were produced by the collapse of neutron stars into black holes. The findings, published in The Astrophysical Journal Letters, provide the most […]
