Mars rover technology tested out on West Highland rocks
The ExoMars programme comprises two missions.The first, called Trace Gas Orbiter, was launched in 2016 while the second has a target launch of 2028, and aims to land the rover on the planet.The robot is named after London-born scientist Rosalind Franklin, who died in 1958.ESA said the missions would tackle the question of whether life has ever existed on Mars.
Dr Claire Cousins of the University of St Andrews said mission technology needed rigorous testing on Earth to make sure it would work on the red planet.She said the rare geology around Lower Diabaig was "ideal" as a testbed.She told BBC Scotland's Landward programme: "The rocks haven't metamorphosed right, they haven't been cooked and squeezed and crushed under mountain belts."They have been beautifully preserved - a slice of time."The rocks include billion-year-old mudstone and other rocks which are stacked one on top of the other in layers.Dr Cousins said: "These are perfect for showing us there was once liquid water - a habitable environment for life."Also, these rocks are very good at capturing evidence of that ancient past biology. It's sandwiched between the rocks."She added: "We don't know yet if there was ever life on Mars, but these are the kinds of rocks that are going to preserve it."
Seven years ago a Nasa Mars rover, Curiosity, explored a part of the planet named after Torridon.Martian geological areas and features have been named by Nasa after places on Earth.Several of the names were taken from Scotland and, as well as Torridon, there is a Siccar Point, Muck, Wick, Sandwick and Holyrood on Mars.Nasa chose the name Torridon due to the Torridonian Supergroup, a geological formation in the north-west Highlands that contains some of the oldest evidence of life of any rocks in the UK.In 2012, Glenelg held a celebration in honour of a location on Mars being named after the small Highland community.

Permission granted for first-of-its-kind British rocket launch
Permission for the first vertical space launch from UK soil by a British rocket company has been granted by the air safety regulator. The licence from the Civil Aviation Authority (CAA) gives Glasgow-based Skyrora the green light to launch its Skylark L rocket from the SaxaVord Spaceport in the Shetland Islands. "Skyrora is proud to be leading efforts that enable launch activity from the UK, and we look forward to achieving a reliable commercial launch programme that benefits us all," said Volodymyr Levykin, CEO of Skyrora. "It is essential that the UK has sovereign launch capabilities." Image: A Skyrora engineer builds a rocket in the company's factory near Glasgow While it's a step towards that goal, the licence doesn't mean the Shetlands will rival America's Cape Canaveral any time soon. Although the CAA licence allows Skyrora up to 16 launches a year, SaxaVord isn't expected to be able to facilitate a launch until early 2026. The current licence is also limited to sub-orbital launches of the 11m tall rocket. Skyrora expects its rocket to reach an altitude of between 120 and 130km - well over the 100km-high "Karman Line", which is the internationally-agreed boundary of space. But Skylark L lacks the heft to access low-earth orbit, the ultimate goal for the emerging "micro launch" industry. Image: A Skyrora engineer works on one of the company's rockets 'Important milestone' Like many of its competitors, Skyrora is using this smaller rocket to test various technologies - and the regulatory environment - before attempting an orbital flight with its larger vehicle, Skyrora-XL. Launching from northern latitudes like the UK offers easier access to satellites in polar or sun-synchronous orbits. Smaller rockets potentially mean cheaper and faster launches, offering a "responsive" launch capability to service or support the increasing number of satellites in orbit. "I am thrilled we've reached this important milestone in the UK space sector, and I congratulate Skyrora for being the first UK company to receive a rocket launch licence," said aviation and space minister Mike Kane. The UK, however, has been criticised for being slow to develop a domestic space capability since the Space Industry Act made it possible back in 2018. The first licence for a UK space launch wasn't granted until 2022, but the attempt by Richard Branson's Virgin Galactic for a horizontal rocket launch from an aircraft failed.

Modifications being made to the SaxaVord spaceport mean it may not be ready to accommodate a launch until 2026. Skyrora told Sky News that if there are significant delays to its plans to launch from SaxaVord, it may look into transferring its CAA licence to Australia's regulator. If so, it expects it could launch SkylarkL from Australia's Woomera test range before the end of 2025. No doubt that would be a disappointment for the UK government and thousands of space enthusiasts in the UK, but it would see history repeat itself. The first (and last) British-built rocket to put a satellite into orbit, Black Arrow, launched from Woomera in 1971. Related Topics

UK grants space launch licence to Scottish firm
LONDON, Aug 5 (Reuters) - Britain has granted its first space launch licence to a homegrown rocket company, paving the way for a Scottish start-up to send satellites into space from the country's first vertical launch spaceport. Skyrora, which was founded in 2017, would be able to conduct up to 16 launches a year, subject to further approval by the UK Civil Aviation Authority (CAA), the regulator said on Tuesday. The Scotland-based company would use the SaxaVord Spaceport in the Shetland Islands, northern Scotland, which received a key safety licence last year, meaning rockets could be launched from the site in the future. Germany's Rocket Factory Augsburg was the first company to gain a licence to launch from the site earlier this year. "Granting a home-grown company, Skyrora its launch licence is a major milestone for our space sector and our nation," CAA Chief Executive Rob Bishton said. The space market is forecast to be worth over $1 trillion by 2030 as companies around the world plan to deploy thousands of internet-beaming satellites. Britain has been looking to add launch capabilities to its space industry, which employs over 45,000 people and builds more satellites than anywhere outside the United States. But those efforts were dealt a major blow in early 2023 when a horizontal rocket launch from Newquay, south-west England, failed. A successful vertical launch from SaxaVord would revive the industry's prospects. "Skyrora is proud to be leading efforts that enable launch activity from the UK and we look forward to achieving a reliable commercial launch programme that benefits us all," its Chief Executive Volodymyr Levykin said. The company needs to meet a number of conditions before any launch, including adequate insurance, a data-sharing deal with the British government and airspace agreements with other countries.

NASA's Curiosity rover can now multitask
NASA 's Curiosity rover, which landed on Mars 13 years ago, has been equipped with significant new capabilities. These upgrades allow the rover to multitask, performing scientific activities while simultaneously conserving energy from its nuclear battery. Curiosity can now communicate with an orbiter, drive, move its robotic arm, and capture images concurrently. The rover can also autonomously decide to power down early if its daily tasks are completed, reducing the need for extensive recharging. These enhancements aim to maximize the lifespan of its power source, as Curiosity continues to explore Martian geological formations believed to be formed by ancient water.
