The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:03 CET (18:03 local time) on board an Ariane 6 launcher from Europe’s Spaceport in French Guiana.

The Sentinel-1 mission delivers high-resolution radar images of Earth’s surface, performing in all weathers, day-and-night. This service is used by disaster response teams, environmental agencies, maritime authorities and climate scientists, who depend on frequent updates of critical data.

Sentinel-1D will work in tandem with Sentinel-1C, flying in the same orbit but 180° apart, to optimise global coverage and data delivery. Both satellites have

Biomass launch

London — Warsaw Increasing tensions with Russia have prompted defense spending boosts throughout Europe that will benefit fledgling smallsat launcher companies across the continent.

SES has turned to Japan’s flagship operator for extra satellite bandwidth to keep up with soaring connectivity demand from passengers flying across Asia, even after significantly expanding its own fleet by buying Intelsat.

From 7 to 10 October 2025, Europe and Africa took another important step toward deepening their cooperation in space. At the ESA Education Training and Learning Facility in ESEC-Galaxia, Belgium, young engineers from across both continents came together for the Space Systems Engineering Training Course, jointly supported by the European Space Agency (ESA) and the African Space Agency (AfSA).

Intuitive Machines, a lunar lander company, announced Nov. 4 it is buying Lanteris Space Systems, a satellite builder formerly known as Maxar.

A Chinese institute recently completed ground tests on what it describes as a reconfigurable flexible on-orbit manufacturing platform, targeting future large-scale, low-cost space manufacturing.

Boston, MA (SPX) Oct 31, 2025 Marco Graffiedi, a doctoral student in nuclear science and engineering, is researching quenching processes to help cool nuclear cores, and NASA craft the next generation of space vehicles. Quenching, a powerful heat transfer mechanism, is remarkably effective at transporting heat away. But in extreme environments, like nuclear power plants and aboard spaceshi

Five launches are planned this week at the two space complexes in central Florida, including doubleheaders on Wednesday and Saturday involving three companies. The missions at Cape Canaveral Space Force Station or Kennedy Space Center would break the record of 93 in one year from Florida's Space Coast. There have already been 91 launches. The week began early Sunday with SpaceX's

Far from Earth, in the vast expanses of space between stars, exists a treasure trove of carbon. There, in what scientists call the "interstellar medium," you can find a wide range of organic molecules - from honeycomblike polycyclic aromatic hydrocarbons (PAHs) to spheres of carbon shaped like soccer balls. In a new study, an international team of researchers led by scientists at the Unive

New experimental research led by Francesca Miozzi and Anat Shahar at Carnegie Science has shown that the galaxy's most common planets may be rich in liquid water due to critical early interactions between magma oceans and primitive atmospheres. Published in Nature, the study demonstrates how these formative processes can deliver water to young worlds. Nearly six thousand exoplanets have be
