The day began with an 85% chance that bad weather would cause a launch delay: it ended with ESA’s Hera mission successfully in space and en route to the Didymos binary asteroid system.

What's inside the moon? Gravity measurements suggest a layer of molten rock
In between the moon's solid core and external surface may swirl a partially molten layer of rock.
Scientists discover bright 'sungrazer' comet that could be visible with the naked eye this month — after Tsuchinshan–ATLAS
Newfound comet C/2024 S1 will light up Earth's skies in late October before a super close slingshot around the sun.
Space-made weld scrutinised in ESA lab
ESA engineers have focused microscopes, hardness testers and an X-ray computer aided tomography machine onto a special aluminium weld just a single centimetre across – the historic result of the very first autonomous welding to be performed in space, and the first ESA has been involved with.
Phew! No 'doomsday' asteroids hide in famous broken comet's debris stream
The Taurid Meteoroid Stream, responsible for two November meteor showers and possibly the Tunguska and Chelyabinsk impacts, probably doesn't hide a civilization-killing asteroid, a new study finds.
Most Mars Meteorites Came From Five Craters
Meteorites strike Earth every day. It’s estimated that about 100 – 300 metric tonnes of material strike our planet every year. Most of it consists of sand-grain sized dust that burns up in the atmosphere, but each year a few thousand will reach Earth’s surface.
NASA Reveals the Mind-Boggling Scale of Hurricane Milton seen from Space
We often talk about Jupiter’s Great Red Spot quite candidly but forget that hurricanes can be devastating, destructive forces here on Earth. Hurricane Milton is a reminder of the awful effects here on Earth. It came out of nowhere, appearing in the Gulf of Mexico as a tropical storm and two days later was a category 5 hurricane. It tracked a course and hit land near Siesta Key in Florida. NASA have been tracking the storm from space, recording high sea temperatures that fuelled the storm allowing it to grow. Images have been released from the ISS showing the sheer enormity of the hurricane.
A New Way to Detect Rocky Exoplanet Atmospheres
The total number of exoplanets discovered to date totals 5,288. Among them are a host of rocky, Earth-like exoplanets but none of them seem to have atmospheres. It’s a fairly challenging observation to make but a team of researchers think they’ve come up with a new, simpler technique. It involves measuring the combined temperature of a star and the exoplanet just before the planet passes behind. If it’s lower than expected, the planet is likely to have an atmosphere regulating its temperature!
We have the satellite data to show climate change is real. Now what?
Free, open source climate data can help bridge the gap between information and environmental action.
How Did Mars Become Uninhabitable?
Mars has captured our imagination for centuries. Ever since the invention of the telescope our imagination has often drifted toward the possibility of life on Mars. Exploration of the red planet has often revealed that Mars once had plenty of water on its surface but it’s no longer there. Now NASA’s Curiosity rover has found deposits of carbon-rich minerals that could give us a much needed clue.
Sound of Earth’s magnetic flip 41 000 years ago
Video: 00:01:20
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.
First all-new MetOp complete and sibling in testing
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.
Severe solar storm could supercharge auroras across US, impact power grids, NOAA warns
A powerful X-class solar flare that erupted on Tuesday (Oct. 8) could generate a strong geomagnetic storm Thursday (Oct. 10) and Friday (Oct. 11), possibly leading to supercharged auroras.
Comet Tsuchinshan-ATLAS photobombs SOHO spacecraft during powerful solar flare (video)
The SOHO spacecraft captured amazing imagery of Comet C/2023 A3 (Tsuchinshan-ATLAS) zooming near the sun as the star unleashed a powerful X flare.
