Daily Brief : July 9: Geothermal scales, deep space patches, astronauts rope-pull

HEADLINE

Quaise Energy raises $134M to drill Earth's hottest rocks while ESA prepares Hera for its closest asteroid encounter in history.

THE BIG PICTURE

Three major milestones crossed in 48 hours, all in the same category: moving from field-proven technology to operational deployment at scale. Quaise has demonstrated millimeter-wave drilling works in real granite; now it funds its first commercial power plant and signs a hyperscaler for 50 megawatts of continuous carbon-free power. ESA successfully patched Hera's flight software across 140 million kilometers of space and will now execute the most complex asteroid orbital insertion ever attempted. And ESA astronaut Sophie Adenot just logged the first human rope-pull workout in orbit, proving new exercise hardware that could replace three older machines for the Lunar Gateway. The engineering proof points are done. The next 90 days are operational validation.

WHAT HAPPENED

Quaise Energy, an MIT-born geothermal startup, announced the first close of a Series B round totaling $134 million, led by Prelude Ventures and including strategic investments from JERA Co. and Idemitsu Kosan, Japan's largest and second-largest integrated energy companies respectively. The capital funds Project Obsidian, the world's first commercial superhot geothermal power plant in Oregon, and continued development of Quaise's millimeter-wave drilling system to depths exceeding 5 kilometers. Quaise has already field-proven the technology: it drilled more than 100 meters through granite at its Central Texas site in 2025 and is now approaching one kilometer depth, the deepest penetration ever recorded by any non-contact drilling method. The company has also signed a hyperscaler customer for the project's first 50 megawatts of continuous power, though the customer remains unnamed. First test drilling for Project Obsidian begins this month, with commercial operation targeted for 2030. CEO Carlos Araque stated: 'This round takes us from field-proven technology to first commercial revenues.'

ESA's Hera spacecraft successfully received a complete software upgrade across 140 million kilometers of space, completing the mission's pre-asteroid-phase readiness checklist. The spacecraft is now configured for its autumn arrival at the Dimorphos and Didymos asteroid system. This represents an unusual deep-space engineering operation: upgrading flight software on an active spacecraft that is simultaneously managing its own navigation and systems across a distance where radio signals require nearly 16 minutes to travel one way.

ESA astronaut Sophie Adenot activated the newly developed E4D (European Exercise Device for Space) inside the Columbus laboratory module, performing the first rope-pulling workout ever conducted in orbit. The E4D is designed to eventually replace three older exercise machines currently required aboard the International Space Station, reducing crew training complexity and launch mass for future Lunar Gateway missions. The first operational workout validates the hardware under real microgravity conditions.

WATCHING

Watch for Quaise's test-well drilling completion later this month and any public announcement of the hyperscaler customer, which would signal how aggressively AI infrastructure is co-funding next-generation power technology. ESA's Hera arrival at Dimorphos will come in autumn; expect daily updates on the spacecraft's orbital insertion sequence once it begins its asteroid approach. Sophie Adenot's E4D workouts will continue over the next weeks; any refinements to the hardware design will inform whether this device becomes standard issue for Lunar Gateway or requires further iteration.
