Test drone maps ice cave in Iceland
Engineers have tested a prototype lidar-equipped drone by flying it through a lava tube in Iceland and using it to automatically map the tube.
While a cave-exploring drone on Earth may use propellers, free-flying spacecraft exploring caves on the Moon, where there is practically no atmosphere, or in the thin air of high altitude lava tubes on Mars’ giant volcanoes, would have to use small thrusters. The mission of the terrestrial drone deployed at the Lofthellir Ice Cave focused on validating the idea of using a drone-equipped LiDAR to safely navigate and accurately map rock and ice inside a dark lava tube in the absence of GPS or any prior map.
Under a research contract with NASA, Astrobotic has developed a custom navigation software product, known as AstroNav, to give drones and small free-flying spacecraft the ability to autonomously explore and map subterranean environments. AstroNav employs both stereo vision and LiDAR, works without GPS or previously stored maps, and can operate in real-time while a novel environment is explored at a high rate of speed.
…”The Astrobotic drone and LiDAR performed exactly as we had hoped, and was able to help us map the Lofthellir Lava Tube in 3D within minutes” says Lee. “We now have a highly accurate model of the shape and dimensions of the cave, and of the configuration of its many rocky and icy features, such as rock falls, ice columns, and micro-glaciers.”
The concept is an excellent one, especially for exploring the caves and pits of Mars. This test however only checked out the lidar. A drone that could do this on either Mars or the Moon does not yet exist.
I have posted their video of the flight below the fold.
Note: Thanks to reader Eddie Willers for noting that I mistakenly located this research in Greenland, not Iceland. Post now corrected.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Small correction. This was Iceland, not Greenland.
You remember…where Sir Oliver Lindenbrook followed Arne Saknussemm’s path to the center of the earth.
Great news. Now there’s no reason to allow anyone in caves, anything worth doing can be done robotically
Glad to hear of progress on the MoonBat concept! I am even hearing rumors that Astrobotic is talking about one for the Moon, even though I have heard no funding talk about it from anywhere. Given the piles of breakdown talus that we find in lava tube caves, rafted into small hills by post-emplacement lava flows, we have less enthusiasm than many for wheeled rovers on the floors of lava tubes. Our team has tried to encourage the MoonBat concept since 1990. It now is moving forward with better speed.
It should be combined with lunar orbiting ground-penetrating radar as a pre-moonbat characterization to find the best tubes before a MoonBat flies inside. Then, after the best tubes characterized by MoonBats are selected, they should be explored by wall-crawling robots using gecko-tech footpads to hold themselves to the ceiling and walls. Finally, a human team can give the OK to send inflatable habitats for a phase 1 lunar base inside the no radiation/no dust/no temperature swing environment of a lunar cave. They can then start tele-operated ISRU operations on the surface to cut costs for future development of the site.
