Lucy is already well on its way to Jupiter’s Trojan asteroids. But that doesn't mean that it can’t make some improvements to its trajectory along the way. A new paper suggests it might be possible to nudge Lucy into a slightly different orbit, allowing it to pass an as-yet-undiscovered asteroid sometime during its exploration of the L5 cloud of Trojan around Jupiter. If completed, it could lend an entirely new research target to Lucy’s repertoire and further define the differences between the two Trojan clouds.

As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a picture of our reality – or even whether that is possible

Europe’s first MetOp Second Generation, MetOp-SG-A1, weather satellite – which hosts the Copernicus Sentinel-5 mission –  has launched aboard an Ariane 6 rocket from the European spaceport in French Guiana. The rocket lifted off on 13 August at 02:37 CEST (12 August 21:37 Kourou time).

MetOp-SG-A1 is the first in a series of three successive pairs of satellites. The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offers enhanced accuracy and resolution compared to the original MetOp mission – along with new measurement capabilities to expand its scientific reach.

This new weather satellite also carries the Copernicus Sentinel-5 mission to deliver daily global data on air pollutants and atmospheric trace gases as well as aerosols and ultraviolet radiation.

Ariane 6 is Europe’s heavy launcher and a key element of ESA’s efforts to ensure autonomous access to space for Europe’s citizens. Ariane 6 has three stages: two or four boosters, and a main and upper stage. For this flight, VA264, the rocket was used in its two-booster configuration.

A SpaceX Falcon 9 rocket lifted off from Florida on Thursday morning (Aug. 14), carrying 28 Starlink broadband satellites into low Earth orbit.

As the planet heats up, the atmosphere is holding more moisture – and this is resulting in more days with weather conditions close to the limits of survivability
