Microsoft has reportedly abandoned plans to serve as the anchor customer for Britain's largest proposed AI supercomputer after learning that the project's Essex data center might not receive sufficient grid power until the early to mid-2030s. "Its departure leaves Nscale without a publicly announced customer for the site, although the neocloud insists the project is still going ahead," reports The Register. From the report: When the deal was announced in September 2025, the plan was to pack 23,040 Nvidia GB300 GPUs into a 50MW facility, with room to expand to 90MW. Microsoft would use the computing power for its Azure cloud services, with the first chips expected in early 2027. One important detail remained: how to power it. As The Guardian reported last month, UK Power Networks warned Nscale that the grid capacity needed might not be available until the 2030s. A UK Power Networks spokesperson told The Register it could not discuss individual connections due to obligations under Section 105 of the Utilities Act. "However, in general, many datacenters, whilst they can connect to our distribution network, are awaiting works on the national transmission network which we do not own," the spokesperson said. Nscale, meanwhile, isn't letting the small matter of losing its biggest customer dampen its enthusiasm. "We remain committed to both the Loughton project and the UK and we are exploring alternative power sources for the site, in addition to other expansion sites in the UK. Our relationship with Microsoft remains strong and long-term, and this unfortunate London-wide grid issue has no impact on our other contracts," Nscale told The Register.

Japan has successfully launched its Martian Moons eXploration (MMX) mission to study Mars' two moons, Phobos and Deimos. Scheduled to arrive in August 2027, "MMX will become the first spacecraft to land on and return samples from Phobos for study back on Earth, which scientists think could shed light on a decades-old mystery about the moons' origins" and resolve whether they were formed from a giant impact or were captured asteroids, reports Space.com. From the report: It was the 10th liftoff of Japan's expendable, two-stage H3 rocket, which was jointly developed by JAXA and Mitsubishi Heavy Industries. After clearing its launch pad today, the 207-foot-tall (63 meters) launch vehicle flew a nominal trajectory through its ascent corridor over the Pacific Ocean, jettisoning its four solid boosters in pairs just before the flight clock reached two minutes. The rocket shed its payload fairings about one minute and 20 seconds later, exposing MMX to the vacuum of space for the first time. [...] MMX is now under its own power, and on course for Mars. The interplanetary transit will last about 10 months, with the spacecraft scheduled to arrive at the Red Planet in August 2027. When it does, MMX's propulsion module will execute an orbital insertion burn to place itself in a quasi-satellite orbit (QSO) around Phobos, which places MMX within the space around the moon as both circle Mars. MMX will spend about three years in the Martian system, devoting much of that time to studying the 14-mile-wide (22 km) Phobos with its science instruments. The spacecraft also carries the IDEFIX rover, a joint effort of the space agencies of France and Germany, which is scheduled to deploy to the surface of Phobos in late 2028 or early 2029. After a mapping campaign to select suitable landing sites, MMX will perform two separate touchdowns on Phobos to collect and stow samples in the spacecraft's return capsule. Following its second landing and sample collection, MMX will briefly return to QSO with Phobos before transferring to a more elongated orbit around Mars that intersects with the planet's smaller moon, Deimos, which is just 8 miles (14 km) in diameter. During the last several months of its time around Mars, MMX will perform a series of Deimos flybys before departing for Earth in November 2030. If all goes according to plan, the MMX sample-return capsule will land in Australia in 2031. You can watch a recording of the launch on YouTube.
