This Could Prevent Rovers From Getting Stuck In Sand Or Dust
Engineers at the University of Wisconsin-Madison uncovered a critical flaw in how lunar and Martian rovers are tested on Earth. Simulations revealed that test results have been misleading for decades because researchers only adjusted rover weight to simulate low gravity—but ignored how Earth’s gravity affects the terrain itself. Using a powerful simulation tool called Chrono, the team showed that sandy surfaces behave very differently on the Moon, where they’re fluffier and less supportive.
Astronomers Detect Most Distant Fast Radio Burst Ever
Astronomers have detected a fast radio burst (FRB) from when the Universe was just 3 billion years old, a remarkable achievement that opens new windows into the early universe and the mysterious phenomena that shaped it.
Stellar Flares Unveil Hidden Magnetic Secrets of TRAPPIST-1
A team of astronomers using the James Webb Space Telescope have achieved a breakthrough in understanding TRAPPIST-1, the famous red dwarf star hosting seven Earth sized planets. By analysing stellar flares, the team discovered that flares cause dark magnetic features on the star's surface to disappear, creating persistent brightening effects. This represents the first-ever measurement of magnetic feature spectra on an M8 dwarf star.
Lucy Could Visit An Additional Sub-km Asteroid With A Course Correction
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.
TRAPPIST-1d isn't the Earth-like planet scientists had hoped it to be, according to JWST data

MetOp-SG-A1 and Sentinel-5: from cleanroom to space
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.
