Airbus to build key systems for ESA's ExoMars lander
Airbus has been chosen by the European Space Agency (ESA) and Thales Alenia Space (TAS), the ExoMars industrial prime contractor, to develop crucial systems for the ExoMars lander. This lander will safely deliver the Rosalind Franklin rover to the Martian surface.
Following atmospheric entry, descent and a parachute-assisted braking phase, the Airbus-built landing platform will ensure a controlled touchdown on Mars and facilitate the rovers deployment onto the surface.
Kata Escott, Managing Director of Airbus Defence and Space UK said: 'Getting the Rosalind Franklin rover onto the surface of Mars is a huge international challenge and the culmination of more than 20 years work. We are proud to have built the rover in our state-of-the-art Stevenage cleanroom and delighted now to develop the project to ensure its safe delivery to Mars. Rosalind Franklin will be the first Martian rover able to analyse samples from two metres below the surface in its search for past or present life. The mission will supercharge our space know-how in the UK, and will advance our collective understanding of our solar system.'
UK Technology Secretary Peter Kyle added: 'This inspiring example of world-class British science will bring us one step closer to answering long-asked questions on potential life on Mars. Landing the first ever home-grown rover on Mars, Airbus will not only help Britain make history and lead the European space race but also bring hundreds of highly skilled jobs and investment as we secure Britains future through our Plan for Change.'
Under TASs leadership, Airbus teams in Stevenage will design the mechanical, thermal and propulsion systems essential for a safe landing in 2030. This includes the landing structure, a propulsion system for final braking thrust, and landing gear to stabilise the lander upon touchdown. The platform will feature two deployable ramps on opposite sides, allowing the rover to select the safest descent route onto the Martian surface.
Airbus engineers in Stevenage have built over 120 propulsion systems for more than 90 spacecraft, supporting telecoms, Earth observation, science and exploration missions. The ExoMars system will use retro rockets to reduce the landers descent speed from 45m/s after the parachute phase to under 3m/s before touchdown.
Airbus originally designed and built the Rosalind Franklin rover in its bio-burden cleanroom in Stevenage, delivering it to TAS in 2019. While the mission was initially scheduled for launch in 2022, it was postponed due to the Russian-Ukraine conflict.
Now, Airbus is collaborating with TAS, ESA and NASA to upgrade the rover ahead of its revised 2028 launch on a NASA-supplied rocket. Updates include integrating NASAs Radioisotope Heater Units (RHUs) to maintain warmth on Mars and introducing a software mode that enables the rover to quickly transition to autonomous operation after landing. The mission is scheduled to land in 2030, strategically avoiding the planets global dust season.

Senegal becomes 56th nation to join Artemis Accords
Senegal is the 56th country to sign the Artemis Accords, which establish a practical set of principles to guide space exploration cooperation among nations participating in NASAs Artemis programme. Senegal has joined the Artemis Accords, becoming the 56th nation to endorse the global framework for peaceful and transparent space exploration. The signing took place during a ceremony hosted by NASA at its headquarters in Washington. Maram Kairé, Director General of the Senegalese Agency for Space Studies (ASES), signed the accords on behalf of Senegal, with participation from Jonathan Pratt, senior bureau official for African Affairs at the US Department of State, and Abdoul Wahab Haidara, Senegals ambassador to the United States. The event follows a recent Washington meeting between Senegalese President Bassirou Diomaye Faye and former US President Donald Trump, as part of broader discussions on US-Africa engagement. Acting NASA Administrator Sean Duffy said: 'Following a meeting between Senegal President Faye and President Trump, today, NASA built upon the strong relations between our two nations as the Senegalese Agency for Space Studies signed the Artemis Accords. With Senegal as the 56th signatory, I am proud to further President Trumps strong legacy of global cooperation in space.' 'Senegals adherence to the Artemis Accords reflects our commitment to a multilateral, responsible, and transparent approach to space,' added Kairé. 'This signature marks a meaningful step in our space diplomacy and in our ambition to contribute to the peaceful exploration of outer space.' Senegal's astronomers have previously collaborated with NASA on scientific missions, including a 2021 campaign to observe asteroid Orus from the ground. During the event, astronomers used telescopes to measure the asteroids dimensions as it passed in front of a star. This data will support NASAs Lucy mission, which will fly by Orus in 2028 as part of its exploration of Jupiters Trojan asteroids. The Artemis Accords, established in 2020 by the United States and seven founding partners, set forth guiding principles for civil space exploration. These include commitments to peaceful use, transparency, international cooperation, scientific data sharing, non-interference and the preservation of space heritage. The accords also encourage development of best practices for sustainable space activity. With growing global interest in lunar and deep space missions, NASA anticipates that more countries will join the Artemis Accords, reinforcing the shared goal of a secure, cooperative and beneficial space environment for all humanity.

Safety measures to protect children from 'toxic algorithms'
Aine Fox, The Independent A generation of children will no longer be "at the mercy of toxic algorithms", the Technology Secretary has declared, as new online safety protections officially came into force. Peter Kyle stated that the government was laying the foundations for a "safer, healthier, more humane online world", issuing a stern warning to tech firms that they "will be held to account" if they fail to adhere to the new measures. The changes, enacted as part of the Online Safety Act and set to be enforced by regulator Ofcom, mandate that online platforms hosting pornography or other harmful content — such as material related to self-harm, suicide, or eating disorders — must implement robust age checks. These can include facial age estimation or credit card verification. Furthermore, platforms are now required to ensure their algorithms do not actively harm children by, for example, pushing such content towards them. Companies found to be non-compliant face severe penalties, including fines of up to £18 million or 10 per cent of their qualifying worldwide revenue, whichever sum is greater. Court orders that could block access to these platforms in the UK are also a potential consequence. Campaigners have underscored the critical need for strict enforcement, with the NSPCC urging Ofcom to "show its teeth" if companies fail to make the necessary changes in line with the regulator's child protection codes. But the Molly Rose Foundation — set up by bereaved father Ian Russell after his 14-year-old daughter Molly took her own life having viewed harmful content on social media — said there is a "lack of ambition and accountability" in the measures, and accused the regulator of choosing to "prioritise the business needs of big tech over children's safety". Mr Kyle insisted the Government has "drawn a line in the sand" and that the codes will bring real change. He said: "This Government has taken one of the boldest steps anywhere in the world to reclaim the digital space for young people — to lay the foundations for a safer, healthier, more humane place online. "We cannot — and will not — allow a generation of children to grow up at the mercy of toxic algorithms, pushed to see harmful content they would never be exposed to offline. This is not the internet we want for our children, nor the future we are willing to accept." He said the time for tech platforms "to look the other way is over", calling on them to "act now to protect our children, follow the law, and play their part in creating a better digital world". He warned: "And let me be clear: if they fail to do so, they will be held to account. I will not hesitate to go further and legislate to ensure that no child is left unprotected." Ofcom chief executive Dame Melanie Dawes has previously defended criticism of the reforms, insisting that tech firms are not being given much power over the new measures, which will apply across the UK. Dame Melanie said: "Prioritising clicks and engagement over children's online safety will no longer be tolerated in the UK. "Our message to tech firms is clear — comply with age checks and other protection measures set out in our codes, or face the consequences of enforcement action from Ofcom." The regulator said X, formerly Twitter, and others including Bluesky, Reddit and dating app Grindr are among those to have committed to age assurances, and described its safety codes as demanding that algorithms "must be tamed and configured for children so that the most harmful material is blocked". It said it has launched a monitoring and impact programme focused on some of the platforms where children spend most time including social media sites Facebook, Instagram and TikTok, gaming site Roblox and video clip website YouTube. The sites are among those which have been asked to submit, by August 7, a review of their efforts to assess risks to children and, by September 30, scrutiny of the practical actions they are taking to keep children safe. Chris Sherwood, chief executive at the NSPCC, said: "Children, and their parents, must not solely bear the responsibility of keeping themselves safe online. It's high time for tech companies to step up." He said if enforcement is "strong", the codes should offer a "vital layer of protection" for children and young people when they go online, adding: "If tech companies fail to comply, Ofcom must show its teeth and fully enforce the new codes". Echoing this, Barnardo's children's charity said the changes are "an important stepping stone" but "must be robustly enforced". England's Children's Commissioner, Dame Rachel de Souza, said Friday "marks a new era of change in how children can be protected online, with tech companies now needing to identify and tackle the risks to children on their platforms or face consequences", and said the measures must keep pace with emerging technology to make them effective in the future. But Andy Burrows, chief executive of the Molly Rose Foundation, said: "This should be a watershed moment for young people but instead we've been let down by a regulator that has chosen to prioritise the business needs of big tech over children's safety."

Trump job cuts: US space agency Nasa to lose nearly 4,000 employees, 20% of workforce
The US space agency National Aeronautics and Space Administration (Nasa) will lose about 3,900 employees under Donald Trump's sweeping effort to trim the federal workforce — at the same time as the president prioritises plans for crewed missions to the Moon and Mars. In an emailed statement, Nasa said around 3,000 employees took part in the second round of its deferred resignation programme, which closed late Friday. Combined with the 870 who joined the first round and regular staff departures, the agency's civil servant workforce is set to drop from more than 18,000 before Trump took office in January to roughly 14,000 — a more than 20 per cent decrease. Those leaving the National Aeronautics and Space Administration on the deferred resignation programme will be placed on administrative leave until an agreed departure date. An agency spokesperson said the figures could shift slightly in the coming weeks. "Safety remains a top priority for our agency as we balance the need to become a more streamlined and more efficient organization and work to ensure we remain fully capable of pursuing a Golden Era of exploration and innovation, including to the Moon and Mars," the agency said. Earlier this year, the Trump administration's proposed Nasa budget put a return to the Moon and a journey to Mars front and centre, slashing science and climate programs. The White House says it wants to focus on "beating China back to the Moon and putting the first human on Mars." China is aiming for its first crewed lunar landing by 2030, while the US program, called Artemis, has faced repeated delays. Nasa is still run by an acting administrator after the administration's initial pick to lead the agency, tech billionaire Jared Isaacman — endorsed by former Trump advisor Elon Musk — was ultimately rejected by the Republican president.
