Nasa's Osiris-Rex capsule will come screaming into Earth's atmosphere on Sunday at more than 15 times the speed of a rifle bullet.

It will make a fireball in the sky as it does so, but a heat shield and parachutes will slow the descent and bring it into a gentle touchdown in Utah's West Desert.

The capsule carries a precious cargo - a handful of dust grabbed from asteroid Bennu, a mountain-sized space rock that promises to inform the most profound of questions: Where do we come from?

Born and raised in the United Arab Emirates, Mr Al Neyadi studied at the University of Brighton.

He graduated in 2004 in electronics and communications engineering before returning to the UAE to pursue a master's degree.

In a post to X, formerly known as Twitter, the former Brighton-based student said he spent "memorable years" in the "beautiful" city.

"Hello from space to all my friends there," he added.

Staff used the "highest-power transmitter" to send a message to the spacecraft and timed it to be sent during "the best conditions" so the antenna lined up with the command, Voyager project manager Suzanne Dodd told AFP.

After communications were lost, the probe had been unable to receive commands or send back data to Nasa's Deep Space Network - an array of giant radio antennas across the world.

The space laser, which was designed to map Earth's winds, re-entered the atmosphere over Antarctica.

Any debris that might have survived the fiery descent would have fallen well out of harm's way.

The British-built spacecraft's mission was hailed a success for the novel data it provided to weather forecasters looking several days ahead.

Ae**us was regarded as something of a revolution.

Climate is the average weather in a place over many years. Climate change is a shift in those average conditions.

The climate has fluctuated naturally throughout the world's history.

But scientists say that there is no doubt that the particularly rapid climate change seen over the past century is caused by humans.

In particular they say it is due to the widespread use of fossil fuels - coal, oil and gas - in homes, factories and transport.

When fossil fuels burn, they release greenhouse gases - mostly carbon dioxide (CO2). These gases trap the Sun's heat in the atmosphere, causing the planet's temperature to rise.

The telescope has other objectives, too, one of which is to show us the detail of how stars are created and how they spawn planets. And it's for this reason that Rho Ophiuchi is a fascinating target for the most powerful observatory in space.

"There's so much going on in this spectacular picture, as young stars splash vibrant colours across the clouds of gas and dust from which they're being born," commented Prof Mark McCaughrean, Esa's senior advisor for science & exploration.

Astronaut Tim Peake is leading the hunt for a great moniker.

He wants everyone to go to a special website set up for the purpose and enter a suggestion. But don't think "Spacey McSpaceFace" is a goer because this is not an online poll.

All ideas will be put before an expert panel and it is they who will make the final choice.

This junk includes old rocket segments; bits that have fallen off satellites; flecks of paint - even tools dropped by spacewalking astronauts.

The concern is that this material is becoming so abundant it could pose a collision hazard to operational missions that provide important services, such as telecommunications and environmental monitoring.

RemoveDebris was designed to test relatively simple - and therefore low-cost - methods of clean-up.

Other missions will try alternatives, including robotic arms that reach out and grab junk. But this kind of approach is very complex and therefore much more expensive to implement.

However, finding even hints of life on an exomoon will be extremely difficult.

"In the Solar System we have no idea whether [icy moons] have life underneath the surface or not. And it's very, very difficult even when we live next door to those objects to make any assessment of what's going on beneath the surface of the ice... Imagine doing that from light-years away," says Dr Kipping.

"Technology has advanced so rapidly that maybe space and time themselves are something that can come under our control."

Wormholes exist at the more speculative end of physics, offering one approach to travelling in time. But Ron Mallett has another.

He has drawn up plans for an actual time machine, and his concept was inspired by a book he read at age 12 about Albert Einstein's equations.

The spacecraft carries a total of 10 instruments. There are various cameras, particle detectors, a radar to map sub-surface features; there's even a lidar, which is used to make 3D maps of surface terrain.

But it is the UK-provided magnetometer that could provide some of the most influential data. The Imperial College London-built experiment will tell us about the properties of the moons' hidden oceans. And at Ganymede, in particular, the information should be quite detailed.

"We'll know the depth of the ocean, its salt content, how de

Bennu and Ryugu have many similarities. They are comparable in size, rich in carbon and shaped like spinning tops. Both missions aim to deliver samples from these objects to Earth.

Both asteroids are primitive objects, made of the same basic material that went into building rocky planets like Earth. Studying samples in laboratories could shed light on how our own world came to be.

The identification of Ryugu as a rubble pile asteroid comes from an assessment of its density. Project scientist Sei-ichiro Watanabe said the asteroid's porosity - a measure of the voids, or spaces, present in the object - was 50%.
