Scientists are investigating whether a strange ‘pit’ spotted on the surface of the Moon could provide a base for humans.Nasa is looking into a large underground cave that may extend beyond the Marius Hills Pit (MHP), a large hole in one of the moon’s most volcanically diverse regions.Scientists say such a cave could one day provide astronauts with a safe haven from radiation and the extreme temperature swings experienced on the lunar surface.
The Geophysical Instruments for Marius Lunar pit Investigation (GIMLI) project, led by the Planetary Science Institute (PSI), will send scientific instruments and robots, built by Honeybee Robotics, to the area to see if the cave could provide safe haven.The project is also being carried out in partnership with the Norwegian Space Agency.‘GIMLI represents the type of ambitious planetary science that PSI was built to pursue,” said PSI director and chief executive Amanda Hendrix.
‘Than and his team are taking a scientific question we’ve been studying from orbit and have developed a way to investigate it directly on the Moon.We’re excited to have PSI leading this effort and to be partnering with Nasa and Honeybee Robotics to learn more about the Moon and its volcanic past.’ Observations from lunar orbit have provided compelling evidence that caves and lava tubes could exist beneath the Moon’s surface.GIMLI will focus on the MHP, as it could provide an opening into underground spaces that may have formed during ancient volcanic activity.
The mission will allow scientists to investigate the pit directly from the lunar surface.PSI Associate Director and Senior Scientist Than Putzig said: ‘It’s long been a desire of mine to reintroduce intentional active-source seismic methods to planetary science, as it has essentially not been done since the Apollo astronauts conducted the first seismic surveys on the Moon.‘Combining that method with ground-penetrating radar and gravity measurements makes it all the more exciting, as these methods together will allow us to get a much better understanding of subsurface properties – including the anticipated detection of a lava tube extending away from the Marius Hills pit.’ GIMLI will use ground-penetrating radar, seismic sensors and a gravimeter to examine what lies beneath the surface.
Up Next Cameras will provide images of the lunar surface and the walls of the pit.Together, the instruments will search for an underground void extending from MHP and, if one is found, help scientists determine its size.Even if GIMLI finds no cave or lava tube beneath the surface, its measurements could help answer an important question: how did the pit form? Studying the surrounding subsurface could provide clues about the origin of MHP, as well as the geology and volcanic history of the region.
The team will also examine the area around the pit.The region has a long history of volcanic activity, while the walls of MHP expose layers of regolith and lava flows that are normally hidden beneath the surface.Studying those layers could reveal how lava travelled across the Moon and whether long periods of time separated different eruptions.
Lunar pits are of interest not only because of the geological record preserved in their walls.Up Next Any underground spaces could also contain evidence of the volcanic processes that shaped the moon.Trending Now 'Lovely' GP killed as she hosted children's sleepover near Sandringham Estate UK 2 minutes ago By Barney Davis First picture of girl, 11, found dead in cricket club after vanishing from home 'American Covid' strain warning after cases surge in England Council sells home for £395,000 and throws in multi-million-pound school by mistake ‘Confirming a substantial lava tube would give us an insight into how volcanism operated on the moon,’ explained Gareth Morgan, PSI senior scientist and deputy principal investigator on the GIMLI programme.
‘Lava tubes are a common feature of basaltic volcanism on Earth, so identifying them on themoon means we could use knowledge of such terrestrial caves to better understand lunar history.’ The wider GIMLI team includes co-investigators from Boise State University, Johns Hopkins University, the Lunar and Planetary Institute and the University of Oslo.MORE: Nasa developing humanoid robots to work alongside astronauts on moon and Mars MORE: Nasa shares image of spooky ‘witch head’ spotted lurking in deep space MORE: ‘Phoenix planet’ born from star’s ashes could tell us what will happen when our sun dies Comments Add as preferred source News Updates Stay on top of the headlines with daily email updates.This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply.
