ESA investigates high-stakes Amazon tipping point
For decades, the Amazon rainforest has quietly absorbed vast quantities of human-generated carbon dioxide, helping to slow the pace of climate change. Recent evidence, however, suggests that this vital natural buffer may be weakening – though uncertainties remain.
To help close this critical knowledge gap, European and Brazilian researchers have gathered deep in the Amazon to carry out an ambitious European Space Agency-funded field campaign.
Sentinel-6B is launched

Copernicus Sentinel-6B was launched on 17 November 2025, ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change. The satellite was carried into orbit on a Falcon 9 rocket from the Vandenberg Space Force Base in California, US.
Sentinel-6B follows in the footsteps of its predecessor, Sentinel-6 Michael Freilich, which was launched in 2020. The mission is the reference radar altimetry mission that continues the vital record of sea-surface height measurements until at least 2030.
Copernicus Sentinel-6 has become the gold standard reference mission to monitor and record
Copernicus Sentinel-6B begins mission to advance ocean science
Copernicus Sentinel-6B launched today, 17 November, at 06:21 CET aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. The satellite was delivered into orbit just under an hour after liftoff, and at 07:54 CET ESA's European Space Operations Centre in Germany received the signal via the Inuvik ground station in Canada, confirming that Sentinel-6B is operational and healt Sentinel-6B launched to extend record of sea-level rise
The latest guardian of our oceans has taken its place in orbit. The Copernicus Sentinel-6B satellite is now circling Earth, ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change.

Morphing 3D-printed structures from flat to curved, in space
Because it's costly and cumbersome to transport large structures such as satellite dishes into space, aerospace Ph.D. student Ivan Wu and his advisor, Jeff Baur in The Grainger College of Engineering, University of Illinois Urbana-Champaign, developed a creative and efficient energy-saving method to morph 2D structures into curved 3D structures while in space.
Wu said what others have done Colorado Boulder advances research and education in space law and policy
University of Colorado Boulder researchers are expanding their work into space law following decades of experience in space exploration.
The need for policy expertise has grown as countries continue to launch satellites, probes, and military hardware into orbit.
