Achieving net-zero by the second half of the century is considered vital if global temperatures are to remain well below the two degrees rise as set out by the Paris Agreement for climate. From their vantage point in space, satellites provide a unique means of tracking progress towards achieving this balance between greenhouse gas emissions from sources and removal by sinks.

How space-based approaches can support the UN Global stocktake, starting in 2023, are the focus of technical discussions at the 2022 United Nations Climate Change Conference (COP27) currently taking place in Sharm El-Sheikh, and feature results from ESA’s trailblazing REgional Carbon

Over the last six months, engineers at Airbus in Stevenage, UK, and teams from Europe and North America have turned a multitude of structural parts and electronic units into a complete satellite: ESA’s Biomass satellite. Now complete, this brand-new satellite has been shipped to Airbus’ testing facility in Toulouse, France, where it will be put through its paces to ensure that it will survive the rigours of liftoff and the harsh environment of space to deliver on its promise, that being to yield new insight into Earth’s precious forests.

Galileo is Europe’s largest satellite constellation – and the world’s most accurate satnav system. The work on Galileo began two decades ago with two test GIOVE satellites, followed by a series of operational launches.

The two GIOVE satellites, the first Galileo In-Orbit Validation satellite and all 34 Galileo Full Operational Capability satellites were tested at ESA’s ESTEC Test Centre, Europe’s largest satellite testing facility.

On this day the very last satellite in the Galileo First Generation series leaves the site, and the people responsible for readying them for space have gathered to say goodbye. Next will come the Galileo

Solar Orbiter has spotted a ‘tube’ of cooler atmospheric gases snaking its way through the Sun’s magnetic field. The observation provides an intriguing new addition to the zoo of features revealed by the ESA-led Solar Orbiter mission, especially since the snake was a precursor to a much larger eruption.

The snake was seen on 5 September 2022, as Solar Orbiter was approaching the Sun for a close pass that took place on 12 October. It is a tube of cool plasma suspended by magnetic fields in the hotter surrounding plasma of the Sun’s atmosphere.

CAPSTONE made its initial insertion into the Near Rectilinear Halo Orbit (NRHO) on Sunday, November 13th. Two smaller correction maneuvers will take place this week to ensure the spacecraft is confirmed into the complex lunar orbit. This NRHO is an orbit around the Moon that has never been flown before and it is the intended orbit for the Gateway space station. NASA intends to use Gateway to sup

The Devonian Period, 419 to 358 million years ago, was one of the most turbulent times in Earth's past and was marked by at least six significant marine extinctions, including one of the five largest mass extinctions ever to have occurred. Additionally, it was during the Devonian that trees and complex land plants similar to those we know today first evolved and spread across the landscape

Rocket Lab USA, Inc. (Nasdaq: RKLB) has been awarded two contracts worth a total of $14 million to provide satellite separation systems for companies building Space Development Agency's (SDA) Tranche 1 Transport Layer (T1TL) satellites. Rocket Lab will supply more than 80 total Lightband Separation Systems (Lightbands) to prime contractor Lockheed Martin and another undisclosed customer, both of

In modern military operations, reconnaissance and counter-reconnaissance have become major determinants of outcomes in combat. Great powers are unprecedentedly reliant on space-based assets, mostly low-orbiting satellites, to spy upon their rivals and adversaries, posing a challenge to those parties on how to detect spy satellites and take countermeasures. Experts have said that the

Spire Global, Inc. (NYSE: SPIR) has unveiled a dark shipping detection solution to track vessels that manipulate their reported position in order to conceal nefarious activities. The Automatic Identification System (AIS) on a vessel helps avoid collisions at sea, track global shipping trends and monitor individual vessel activity; but crew members on board can manipulate the system by turn
