PARIS (ESA PR) — Lunar caves are not only a geologically pristine record of the Moon’s history, but they could also provide a safe home for future human explorers. Building upon ESA Discovery’s OSIP call and SysNova challenge, ESA gathered a spectrum of over 60 experts in many different areas of science and engineering to design a mission to enter a pit on the Moon’s surface and explore the entrance to a lunar cave.

The Moon is dotted with pits that scientists think could lead to huge underground tunnels. But a space mission has never been sent to explore what could lie within.

“A view into the interior of a lunar cave would be true exploration – it would reveal unexpected scientific information,” says Francesco Sauro, cave scientist and planetary lava tube expert, as well as technical course director of ESA CAVES and PANGAEA.

PARIS (ESA PR) — In a first step towards uncovering the Moon’s subterranean secrets, in 2019 we asked for your ideas to detect, map and explore lunar caves. Five ideas were selected to be studied in more detail, each addressing different phases of a potential mission.
