NASA has unveiled a significant shift in its moon and Mars strategy, allocating $20bn over the next seven years to construct a base on the moon's surface. This move comes as part of a broader overhaul of NASA's long-term Moon-to-Mars strategy, aimed at supporting long-term human presence on the lunar surface.NASA Administrator Jared Isaacman outlined the changes, which include increasing robotic missions to the moon and laying the groundwork for nuclear power on the lunar surface. The agency plans to repurpose some components of the Lunar Gateway station for use on the moon's surface instead of building the station in lunar orbit.The planned moon base will be supported by robotic missions that will help prepare the site, test technologies, and begin building infrastructure before astronauts return later this decade. Additionally, NASA disclosed plans to launch a spacecraft called Space Reactor 1 Freedom before the end of 2028, a mission designed to demonstrate nuclear electric propulsion in deep space on the way to Mars.The spacecraft will deliver helicopters on Mars, similar to the Ingenuity robotic test helicopter that flew with NASA's Perseverance rover. This step aims to move nuclear propulsion technology from laboratory testing to operational space missions. The changes to NASA's flagship Artemis programme are reshaping billions of dollars' worth of contracts and come as the United States faces growing competition from China, which is aiming to land astronauts on the moon by 2030.

In a groundbreaking experiment conducted in Colorado's Rocky Mountain meadows, scientists heated a patch of land by 2C for 29 years. The results are alarming: the area transformed from a lush, diverse grassland into a desert-like scrubland dominated by sagebrush. This 'shrubification' process, driven by rising temperatures, threatens the very existence of alpine grasslands worldwide.The experiment, conducted at the Rocky Mountain Biological Laboratory, involved warming five plots of 30 sq meters each by 2C using electric infrared radiators. The results showed a 150% increase in shrubs in warmed plots compared to those without heating. The surface soil dried by up to 20%, and shallow-rooted plants became stressed, leading to the extinction of some wildflowers.The implications extend far beyond Colorado. Alpine grasslands, which host 50% of European flora on just 3% of land, are particularly vulnerable. As temperatures rise, these ecosystems are likely to be irrevocably changed, leading to a loss of biodiversity. The phenomenon of 'shrubification' is not limited to mountain environments; it's also observed in Arctic landscapes, where shrub cover expanded by 2.2% each decade between 1984 and 2020.Conservation ecologists warn that while shrubs and trees bring benefits like shelter and carbon sequestration, their rapid expansion in cold environments is a symptom of climate change. The speed and scale of these changes are concerning, with potential knock-on impacts on the carbon cycle and ecosystem balance.As Lara Souza, lead researcher, notes, 'It's like flowers on steroids.' However, this vision of abundance is tinged with sadness at the prospect of irreversible changes to fragile landscapes. The future of these ecosystems, and many others like them, hangs in the balance as global temperatures continue to rise.

Rob Petit's documentary Underland, inspired by Robert Macfarlane's bestselling book, delves into the mysterious world beneath the Earth's surface. The film features Mexican archaeologist Fátima Tec Pool exploring cenotes on the Yucatan peninsula, theoretical physicist Mariangela Lisanti studying dark matter in an ultra-clean facility in Canada, and urban explorer Bradley Garrett navigating storm-drain tunnels in Las Vegas.The documentary intertwines these experiences with Sandra Hüller reading poetic prose about the 'nether' in a faintly Americanised accent. While the film raises intriguing ideas, it sometimes struggles to reconcile natural underground spaces with human-made ones. The most striking scenes showcase Lisanti's work searching for dark matter, highlighting the vastness of deep time and the potentially fruitless pursuit of scientific discovery.The film is set to release in UK and Irish cinemas on 27 March, offering viewers a chance to explore the hidden world beneath their feet.

Recent drone footage has surfaced, depicting the devastating aftermath of an Iranian missile attack in Tel Aviv. The footage, obtained from a reliable source, provides a glimpse into the destruction caused by the missile strike.The attack, which occurred on March 24, 2026, has raised tensions between Iran and Israel, with the international community closely monitoring the situation.The drone footage shows significant damage to buildings and infrastructure in the affected area, highlighting the severity of the attack. Authorities have reported multiple casualties and injuries, with rescue efforts underway to assist those affected.The incident has sparked global concern, with world leaders condemning the attack and calling for restraint. The situation remains fluid, with diplomatic efforts underway to de-escalate tensions between the two nations.

Iranian officials have strongly dismissed claims of secret talks with the United States, amid ongoing tensions between the two nations. The reports, which surfaced recently, suggested that high-level discussions were underway to address key issues, including Iran's nuclear program and regional security concerns. However, Iranian authorities have firmly denied these allegations, stating that there have been no such talks. The denial comes at a time when relations between Iran and the US remain strained, with both countries having imposed significant sanctions on each other. The situation highlights the complex and often contentious nature of US-Iran relations, which have been marked by periods of heightened tension and diplomatic efforts. The Iranian government's stance on the matter underscores its commitment to its current policies and its resistance to external pressures.

NASA has announced a significant shift in its lunar exploration strategy, cancelling plans for a lunar orbit space station known as Gateway. Instead, the agency will utilize the station's components to construct a $20bn base on the moon's surface over the next seven years.The decision was made by NASA's new chief, Jared Isaacman, who was sworn in at the agency in December. Isaacman outlined the changes to the agency's flagship moon program, Artemis, at an event at NASA's Washington headquarters."It should not really surprise anyone that we are pausing Gateway in its current form and focusing on infrastructure that supports sustained operations on the lunar surface," Isaacman told delegates at the event.The Lunar Gateway station, largely already built with contractors Northrop Grumman and Lanteris Space Systems, owned by Intuitive Machines, was meant to be a space station parked in a lunar orbit. Repurposing the craft for a lunar surface base is not simple, but Isaacman emphasized that the agency can repurpose equipment and international partner commitments to support surface and other program objectives.The changes imposed by Isaacman on the flagship US moon program in recent weeks are reshaping billions of dollars' worth of contracts under the Artemis effort, sending companies scrambling to accommodate the extra urgency as China makes progress toward its own 2030 moon landing.

Huw Edwards, the former BBC presenter, has publicly criticized Channel 5 for producing a drama about his downfall without first verifying the facts with him. The two-part show, titled Power: The Downfall of Huw Edwards and starring Martin Clunes, aired on Channel 5.Edwards was suspended from his role as a leading news anchor in 2023 after allegations surfaced that he had paid a teenager £35,000 for intimate images and conversations. He has since disputed the principal allegations made in the Sun.In a statement, Edwards expressed his disapproval of the production company Wonderhood, stating that they made no attempt to check the truth of their narrative before producing the drama. He also criticized Channel 5 for not allowing him to respond to the allegations before the show aired.Edwards added that he plans to produce his own account of the events and expressed deep regret and remorse for his crimes, having received a six-month sentence suspended for two years for possessing indecent images of children.A Channel 5 spokesperson defended the drama, stating that it was based on extensive interviews with the victim, his family, and court reporting, and that all allegations were put to Edwards via his solicitors before transmission.

Huw Marc Bennett's third album, Heol Las (Blue Street), takes traditional tunes from Glamorgan and submerges them in languid arrangements, touched by global influences and woozy doses of surf rock and sitar. The album thrums with a fitting beauty and energy, as it drifts from the industrial valleys to the Gower peninsula.The album features synthesiser-driven tracks such as Cân Gwasael (Wassail Song) and Yr Abaty (The Abbey), which sound like lost library-music theme tunes for spooky children's TV dramas. Other tracks, such as Y Fedwen (The Birch), are like sparkling radio-friendly nuggets of lost Sain Records psychedelia.Bennett's album also explores themes of Welsh heritage and identity, with Angela Christofilou adding lyrics inspired by Bennett's nieces being the first generation in his family to experience Welsh-medium education. The album is a revitalising and revelatory blend of Wales's past and future.Other notable albums out this month include Joshua Burnside's It's Not Going to Be Okay, Akkajee's Pölynkerääjä (The Dust Collector), and the Weaving's Dlúth & Inneach (Warp & Weft).

NASA has initiated the process of returning its massive Space Launch System (SLS) rocket and Orion spacecraft to the launch pad at Kennedy Space Center in Florida. This move comes after completing necessary repairs, setting the stage for a potential launch on April 1.The operation, which can take up to 12 hours, began at 8pm local time. The rocket and spacecraft will be moved 4 miles (6.5km) to launch pad 39B. If all tests are satisfactory, the mission will proceed with a crew of three US astronauts and one Canadian set to fly around the moon.This mission, expected to last about 10 days, marks a significant step towards achieving the goal of returning humans to the lunar surface. The Artemis 2 mission had faced several delays, including issues with helium flow and a liquid hydrogen leak during a previous wet dress rehearsal.The Artemis 2 astronaut crew entered quarantine in Houston as they prepare for liftoff. With the April 1 launch window approaching, NASA remains hopeful that this mission will successfully launch in early April, paving the way for future lunar exploration.
