Oldest footprints of first ‘reptile' found by fossil hunters
More than 300 million years ago, long before the age of dinosaurs, there lived a four-legged, clawed creature that had evolved to survive and reproduce entirely on land, away from the shark-swarmed seas where its ancestors first appeared.
It could lay eggs on land, unlike amphibians. The creature was part of a large group known as 'amniotes.'

Trump's Threat to Kill SpaceX Presents One Hidden Safety Concern
Because of a political fallout, tech mogul and SpaceX owner Elon Musk has now attracted the verbal ire of President Trump. While sparring over social media, the President suggested that he could and would cancel Musk's government contracts relative to SpaceX. Briefly, this led Musk to claim that SpaceX would "decommission" the crucial Dragon spacecraft, but later reversed his position, saying, "Ok, we won't decommission Dragon." This is the very same type of vessel which recently led to the rescue of astronauts Butch Wilmore and Sunni Williams who were stranded on the International Space Station for much longer than originally planned. And it's the fate of the International Space Station that is actually the number one reason why an utterly defunded SpaceX might be a very dangerous thing. In 2024, NASA awarded SpaceX a contract valued at $843 million. The purpose? To deorbit the International Space Station by the end of the decade. Basically, the ISS is not designed to stay in orbit forever, and before it is replaced by something more permanent, it will have to be safely moved to a low Earth orbit. This means that SpaceX is currently tasked by the U.S. government to build the United States Deorbit Vehicle (USDV). "Selecting a U.S. Deorbit Vehicle for the International Space Station will help NASA and its international partners ensure a safe and responsible transition in low Earth orbit at the end of station operations," Ken Bowersox said in a NASA statement last a hypothetical world in which Trump decides to rescind all government contracts for SpaceX, that would presumably include killing the all-important job of SpaceX building the USDV. And if SpaceX doesn't build the USDV, who will help mitigate the very real fallout of a large space station? Again, hypothetically, there are other organizations that have spacecraft, but as the stranding of Wilmore and Williams recently demonstrated, SpaceX has proven to be the most reliable way for the U.S. to get people in and out of space. In fact, the whole reason that Wilmore and Williams were stranded was because the Boeing Starliner — a rival aerospace venture to SpaceX — was unable to complete a return trip because of safety concerns. Concurrent with all of this, Blue Origin's New Glenn craft isn't even close to being ready. Notably, Blue Origin's other craft, the New Shepard, isn't designed to go far enough into space to be useful to the ISS. One might wonder if SpaceX really needs the money. And it's possible the company doesn't. As Musk pointed out on June 3, the entirety of what NASA pays to SpaceX ($1.1 billion) is dwarfed by SpaceX's current revenue ($15.5 billion). Basically, SpaceX's Starlink services are making plenty of money for the company, so if Trump rescinded even just that contract valued at roughly $800 million, it wouldn't come close to putting SpaceX out of business. Legally, Trump might be able to try and sever ties between SpaceX and the U.S. government, specifically, NASA. But practically speaking, this seems very unlikely long-term. Right now, SpaceX is the best bet for creating a safe deorbit for the ISS. And, if any more astronauts get stranded — from any country — it seems like Musk's Dragons are still the most reliable space Threat to Kill SpaceX Presents One Hidden Safety Concern first appeared on Men's Journal on Jun 6, 2025

Elon Musk Walks Back Threat to Decommission SpaceX's Dragon Spacecraft amid Ongoing Trump Feud
Elon Musk appears to have walked back a threat to decommission SpaceX's Dragon spacecraft amid his ongoing feud with President Donald Trump The comment was made after Trump had threatened to pull the billionaire's government contracts and subsidies In June 2024, NASA awarded SpaceX a $843 million contract to help deorbit the ISS, which will see the end of its operational life in 2030Elon Musk threatened to decommission SpaceX's Dragon spacecraft amid his feud with President Donald Trump, but seemingly has already walked back that claim. Tensions between the SpaceX CEO and the 47th president of the United States escalated on Thursday, June 5, just days after Musk announced he was departing the new Department of Government Efficiency (DOGE). On Tuesday, June 3, Musk criticized Trump's "Big Beautiful Bill" on X, calling it a 'massive, outrageous, pork-filled Congressional spending bill' and 'a disgusting abomination.' Trump shot back at Musk in a post shared Thursday on Truth Social, saying 'the easiest way' for the U.S. government to save money is to "terminate Elon's Governmental Subsidies and Contracts.' Musk rebutted on X a short time later. 'In light of the President's statement about cancellation of my government contracts, @SpaceX will begin decommissioning its Dragon spacecraft immediately,' he wrote. A few hours later, however, Musk appeared to walk back his comment after a user by the name of 'Fab25june' suggested the SpaceX founder 'cool off and take a step back for a couple of days.' 'Good advice,' Musk replied. 'Ok, we won't decommission Dragon.' The Dragon spacecraft has completed more than 50 missions, including 46 visits to the International Space Station (ISS), according to its website. According to SpaceX, the ship 'is capable of carrying up to 7 passengers to and from Earth orbit, and beyond' and 'is the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth, and is the first private spacecraft to take humans to the space station.' In June 2024, NASA announced SpaceX was awarded a $843 million contract to help deorbit the ISS, which will see the end of its operational life in 2030.
