Explore Mars is not easy. At different times on the surface of the planet, several masrohodov and landing modules worked, and the orbiters were observed on the top of the Red Planet. For example, now Curiosity is working at the bottom (“Opportunity never got in touch), and Mars Reconnaissance Orbiter (MRO) probe is watching him from above. The problem is that although spacecraft are capable of taking photographs of the surface of the planet in high resolution, satellite imagery lacks detail. Explore Mars with the help of rovers is also not very convenient - they move slowly. Understanding these shortcomings, researchers from the University of Arizona (USA) came up with a new concept that, in their opinion, would save a lot of money in further attempts to study the Red Planet with the help of robotic devices.
Scientists suggest using an inflatable glider,which will weigh only 5 kilograms and have a wingspan of 5.7 meters. According to the proposed concept, the glider will be able to fly over the Martian landscape and make a detailed view from a bird's-eye view. According to the developers, such a device for one Martian day (sol) will be able to overcome distances from 10 to 100 kilometers, which more than one rover is not capable of.
"The proposed concept of an inflatable airframeprovides a completely new way to accelerate the study of the surface of Mars at a fraction of the cost that would be required to implement the earlier concepts of the aircraft for the study of the Red Planet, ”the document says.
Sophisticated design, available as a preprint indatabase arXiv, go to the Red Planet in Kubsat. Then a small spacecraft entering the atmosphere will lower it onto the surface of Mars, where a telescopic boom will hold the glider until the design of its wings is turned by pumping nitrogen into special compartments.
Developers offer to cover the main partwing design special material sensitive to ultraviolet radiation, which will harden under the influence of sunlight. The process of solidification will take about an hour, after which the design of the planet will become tough enough so that it can continue its independent flight.
As a propulsion system planetIt is proposed to use a system based on cold gas. It will allow the device to rise to a height of 1.8 kilometers above the surface of the planet and from there carry out the necessary scientific activities.
The task of such a drone will be held as inassistance to mars rovers located on the surface of the Red Planet, as well as independently searching for potentially suitable places for the establishment of Martian colonies.
