MIT Scientists Design a ‘Flying Saucer’ That Could Float Across The Moon

Researchers have imagined a lightweight, traveling saucer-style rover that can float throughout the surface area of the Moon and other airless planetary surfaces these as asteroids.

The ‘flying saucer’ would be powered by the electrical discipline that builds up because of to immediate publicity to the Solar and its surrounding plasma. In the absence of an atmosphere, this solar publicity makes a cost which is able to levitate dust more than a meter (much more than 3 ft) above the lunar floor, and it could be attainable to harness this electricity.


The rover would be built of a material identified as Mylar, which the natural way retains the very same cost when hit by the Sun’s rays. Small ion beams would be employed to both of those demand up the automobile and increase the pure surface charge, counteracting gravity.

“With a levitating rover, you really don’t have to stress about wheels or going areas,” claims aerospace engineer Paulo Lozano, from the Massachusetts Institute of Technological innovation (MIT).

“An asteroid’s terrain could be absolutely uneven, and as lengthy as you had a managed mechanism to hold your rover floating, then you could go over quite rough, unexplored terrain, without having possessing to dodge the asteroid bodily.”

The ion thrusters, identified as ionic-liquid ion resources, are little nozzles that have previously been employed to propel satellites via house. The genuine gasoline is molten salt, which when strike with an electrical charge, shoots out of the nozzles as a beam.

Here, the cost is transferred to the surface area underneath to dietary supplement its individual pure cost. Mathematical styles verified the strategy could function, and would present sufficient of a thrust to get the gliding rover off the floor.

In a lab experiment utilizing ionic-liquid ion resources to make an electrostatic force, the crew was in a position to get a little, palm-sized motor vehicle weighing about 60 grams (2.1 ounces) to levitate. The quantity of pressure necessary would depend on the measurement of the planetary physique.

“This type of ionic design utilizes incredibly minor power to deliver a large amount of voltage,” states Lozano. “The ability essential is so little, you could do this practically for cost-free.”

When you’re packing for a journey to the Moon (or anyplace else in room), it really is critical to pack as mild as achievable – heavier hundreds have to have much more gasoline and cost extra cash to start. In this scenario, the proposed probe would be sourcing a ton of its ability by natural means.


The current investigation only proves that levitation is doable. In purchase to get the rover up to a respectable height, more modeling is likely to be needed, the scientists say – but the fundamental calculations check out out.

Significant asteroids like Psyche could also be explored by this sort of rover, offering experts a way of analyzing these rocky bodies up shut with a motor vehicle that just isn’t fazed by uneven surfaces and which can attract some of its ability from pure electric powered fields.

“We think of making use of this like the Hayabusa missions that had been released by the Japanese house company,” claims Oliver Jia-Richards, a NASA Place Technology Investigation Fellow from MIT.

“That spacecraft operated close to a little asteroid and deployed tiny rovers to its surface area. Equally, we imagine a long run mission could deliver out modest hovering rovers to explore the surface area of the Moon and other asteroids.”

The investigate has been published in the Journal of Spacecraft and Rockets.
