Mars

One day on Mars is about 37 minutes longer than an Earth day – but it seems both planets are working to fix the gap. Data from NASA’s InSight lander have revealed Martian days are getting ever so slightly shorter, and scientists aren’t sure why.

In a scary first, scientists have discovered a 2021 solar eruption so large that it was, for the first time, detected simultaneously on Earth, the Moon, and Mars, highlighting the radiation dangers posed by such events to deep space travelers.

In anticipation of one of history's most ambitious planetary missions, NASA has successfully tested the two solid rocket motors that will be used to help return the first geological samples from Mars to Earth for laboratory analysis.

As far as landscapes go, Mars is pretty dull – it’s mostly just rocks and craters. But now the Perseverance rover has spotted a couple of particularly weird rocks that have been hollowed out in eerie shapes.

After over two months of silence, NASA has been able to reestablish contact with its wayward Ingenuity robotic helicopter on Mars after radio transmissions were blocked by a hill. This marks what is now the official end of flight 52.

At the Paris Air Show, the space agencies of France, Germany and Japan signed an agreement that will allow a robotic Franco-German rover aboard Japan's Martian Moon eXploration (MMX) mission and land it on the surface of the Martian moon Phobos.

A bright red waterfall isn’t something you’d expect to see on the icy landscape of Antarctica, but that’s what’s pouring out from the foot of Taylor Glacier. Scientists now claim to have solved the mystery behind the crimson waters of Blood Falls.

Researchers are asking meteorite hunters to refrain from using magnets to test the authenticity of their finds because this can destroy the specimen's magnetic memory, erasing valuable information about the nature of the solar system.

The mission may be defunct, but NASA’s InSight Mars lander is still discovering new things about the Red Planet. Scientists poring over data have now made the first direct observations of another planet’s core, and it’s not quite what we thought.

The first aircraft to fly on another planet has hit a new milestone. NASA’s Ingenuity Mars Helicopter has recently clocked up its 50th flight, and achieved a new altitude record in the process.

If you’re looking for some Red Planet real estate, there’s a new tool that could help you pick out the very best spot. Caltech scientists have created a nearly complete global map of Mars at an extremely high resolution of 5 m (16.4 ft) per pixel.

The race is on to find viable materials for building on other planets, and one team has (thankfully) moved on from its last creation made of blood and urine to unveil a new biocomposite brick that's not only much stronger but a little more palatable.
