Approximately 41 000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere.
With all instruments integrated, the first MetOp Second Generation-A, MetOp-SG-A1, weather satellite is now fully assembled and on schedule for liftoff next year. Meanwhile, its sibling, MetOp-SG-B1, is undergoing rigorous testing to ensure that it will withstand the vacuum and extreme temperature swings of space.

As comets travel along their orbit they dump material along the way. A stream of debris known as the Taurid swarm has been keeping astronomers attention. It’s thought the debris is the remains of comet Encke which has also been fuelling the Taurid meteor shower. The swarm is believed to be composed of mostly harmless, tiny objects but there has been concern that there may be some larger, kilometre size chunks. Thankfully, new observations reveal there are of the order of 9-14 of these 1km rocks.
NASA has sent a whole host of spacecraft across the Solar System and even beyond. They range from crewed ships to orbit and to the Moon to robotic explorers. Among them are a range of mission classes from Flagships to Discovery Class programs. Now a new category has been announced: Probe Explorers. This new category will fill the gap between Flagship and smaller missions. Among them are two proposed missions; the Advanced X-ray Imaging Satellite and the Probe Far-Infrared Mission for Astrophysics.

ESA’s Mars Express has captured an astonishing array of landforms emerging from a thick winter blanket of frost as spring arrives in the south polar region of Mars. Some of these features are surprisingly dark compared with their icy surroundings, earning their nickname of ‘cryptic terrain’.
The Sentinel-1C satellite, the third satellite of the Copernicus Sentinel-1 mission, has arrived at the European spaceport in French Guiana for liftoff on the Vega-C rocket at the end of 2024. The satellite will continue the critical task of delivering key radar imagery of Earth’s surface for a wide range of Copernicus services and scientific applications.
