This ancient history, scientists hope, is now recorded in the "amazing" rock samples that will be laid down in "a depot" in the next couple of months.

"If [Jezero's ancient] conditions existed pretty much anywhere on Earth at any point in time over the last 3.5 billion years, I think it's safe to say, or at least assume, that biology would have done its thing and left its mark in these rocks for us to observe," said David Shuster, a Perseverance mission scientist from the University of California, Berkeley.

Much of the enormous thrust comes from burning almost three million litres of super-cold liquid hydrogen and oxygen in four big engines on the vehicle's underside.

But when controllers sent the command early on Saturday morning to fill the rocket's hydrogen tank, an alarm went off, indicating there was a leak.

The problem was traced to the connection where the hydrogen was being pumped into the vehicle.

Controllers tried a number of fixes, including allowing the hardware to warm up for short periods to reset the seal, but they were not successful.

Artemis 1, which is due to launch on Monday, will send the capsule around the Moon and back, to test systems and procedures ahead of a crewed flight in 2024.

Goonhilly, near Helston on the Lizard Peninsula, will track the capsule over a six-week period.

Clearly, you can't simply send a vehicle designed for one planetary body to a completely different world and expect it to work. The current concept would need modifications.

"The surface of Mars and the surface of the Moon are very different. The terrain is different, and the dust is different. The dust on the Moon is very abrasive and sticky," explained Adam Camilletti, who worked on the Airbus rover concept in its early days but is now with the UK Space Agency.

"One major consideration is the thermal environment. A Mars rover gets rid of heat in a different way to one on the Moon. And things like the solar cells - Mars is obviously a lot further away from the Sun, so the whole power system would have to be designed differently to work on the Moon."

US President Joe Biden this week described Dart as one of the US space agency's three great successes of 2022 - the other two being the recent Artemis-1 Moon mission and the first pictures from the new super space telescope James Webb.

Dr Tom Statler, Nasa's Dart programme scientist, agreed.

"Dart has been a tremendous success. Of course, one successful mission doesn't guarantee that Earth is automatically safe from anything that might come our way. But Dart is truly a giant step toward our goal of making asteroid impacts on Earth preventable, and not inevitable."

The Dart team has been delivering its first major tranche of scientific results to the American Geophysical Union Fall Meeting in Chicago.

The objective is to gather more information regarding potential habitability so that subsequent missions can address the life question more directly.

Already scientists are thinking about how they could put landers on one of Jupiter's frozen moons to drill through its crust to the water beneath.

In Earth's Antarctica, researchers use heat to bore hundreds of metres through the ice sheet to deploy submersibles in places where the local ocean is frozen over.

It's challenging work and would be an even greater task on a Jovian moon where the ice crust might be tens of kilometres thick.

Europe has had its own meteorological spacecraft sitting high above the planet since 1977. The new imager is the third iteration in the series.

Meteosat-12 sits in a "stationary" position, keeping a permanent eye on Europe, the Middle East and Africa.

It will return a full picture of the weather systems racing across Earth's surface at a rate of one every 10 minutes, five minutes faster than has been the case up to now. It also views the planet in more wavelengths of light. Sixteen instead of the previously available 12.

The additional bands of light allow for true colour images. In other words, the pictures are much closer to what the human eye might perceive if looking down from the same vantage point.

A Chinese robot has started exploring the far side of the Moon.

The Chang'e-4 probe will explore the surface and carry out geological experiments. China plans to follow this up with further missions to return Moon rock to laboratories on Earth.

But it's not just scientists who are fascinated with the Moon's hidden face.

Musicians, film-makers and, of course, conspiracy theorists have all been inspired by that secret, barren landscape.

In the meantime, the researchers who study Venus's surface have relied heavily on data from Magellan - a Nasa mission that ended in 1994. A European mission, Venus Express, and a Japanese spacecraft, Akatsuki, have been there since, but both are focused on atmospheric science.

After years of feeling like a new mission would never happen, there is a sense that the tide might finally be turning.

The European Space Agency (Esa) is evaluating a Venus mission, called EnVision, alongside two astronomy proposals - Theseus and Spica. Other concepts are also being proposed to Nasa.

Early career researchers are now choosing to join the field again in numbers. And scientists with backgrounds in other disciplines are lending their expertise, bringing new ideas.

The encounter will be very different from that of Rosetta at 67P. Interceptor will not orbit the comet; it will just fly past - hopefully not too quickly.

Nor will Interceptor try to repeat the landing of Rosetta's little robot, Philae.

Instead, it will be the job of those daughter craft to see if they can get in a bit closer to the comet than the mothership to acquire some more detailed information.

"The main spacecraft has the propulsion, the high-gain antenna to talk to Earth, and some instrumentation on it. That passes relatively far from the comet, about 1,000km or so upstream of the nucleus of the object. And then we deploy two cubesat-like probes that go a lot closer and do the high-risk, high-reward observations," deputy PI Dr Colin Snodgrass, from the University of Edinburgh, told BBC News.

Two of the most exciting space missions of the 2030s are likely now to be launched within a year of each other.

European Space Agency member states are poised to increase the organisation's science budget on Thursday by 10%.

This would make it possible to align projects to build a big X-ray telescope and a trio of satellites to sense the collision of gargantuan black holes.

It's important they fly together because the insights they'll bring are highly complementary.

The elephant was born on 5 May 2014 and was the first baby elephant birthed at the park.

He started the journey to his new home on Tuesday, a reserve with 20 acres of habitat and a large plantation for him to roam.

Safari park head elephants keeper Andy Plumb said it was a "bittersweet time for me and the elephant team to see Sutton leave us".

He added: "Unfortunately, African elephants face an uncertain future, with the wild population declining, meaning they are listed as 'endangered'.
