The physicist trying to build humanity's lunar future with moon dirt

When it comes to sending humans back to the moon, knowing how to work with the regolith that coats the ground will be make-or-break. Phil Metzger is studying how to mitigate its dangers and use it as a crucial resource

n 2025 BepiColombo image1 Top three images from BepiColombo's sixth Mercury flyby 09/01/2025 619 views 4 likes ESA / Science & Exploration / Space Science / BepiColombo On 8 January 2025, the ESA/JAXA BepiColombo mission flew past Mercury for the sixth time, successfully completing the final ?gravity assist manoeuvre? needed to steer it into orbit around the planet in late 2026. The spacecraft flew just a few hundred kilometres above the planet's north pole. Close-up images expose possibly icy craters whose floors are in permanent shadow, and the vast sunlit northern plains. At 06:59 CET, BepiColombo flew just 295 km above Mercury's surface on the planet's cold, dark night side. Around seven minutes later, it passed directly over the Mercury's north pole before getting clear views of the planet's sunlit north. European Space Agency (ESA) Director General Josef Aschbacher revealed the first image during his Annual Press Briefing on 9 January. As during BepiColombo's previous flybys, the spacecraft's monitoring cameras (M-CAMs) did not disappoint. This flyby also marks the last time that the mission's M-CAMs get up-close views of Mercury, as the spacecraft module they are attached to will separate from the mission's two orbiters ? ESA?s Mercury Planetary Orbiter and JAXA?s Mercury Magnetospheric Orbiter ? before they enter orbit around Mercury in late 2026. Celebrating the M-CAMs' final hurrah, let's explore the best three images from BepiColombo's sixth close encounter with the little planet, and what they reveal about mysterious Mercury.

On 22 August 2024, summit staff reinstalled Rubin Observatory's commissioning camera (ComCam) on the telescope. ComCam has previously been on the telescope, but was removed before the installation of the secondary mirror in late July. ComCam ??? a smaller (144 megapixel), simpler version of the full 3200-megapixel LSST Camera ??? is being used for testing activities prior to installing the LSST Camera, anticipated to happen late 2024. In the coming weeks the summit team will install the primary/tertiary mirror, enabling ComCam to produce the first astronomical data from the Simonyi Survey Telescope.
