Road? Noodles? aliens? After a lot hypothesis, NASA just lately revealed an article explaining the doable origin of a wierd fibrous object found on the floor of Mars by the Perseverance rover.
According to the house company, this object was half of the chassis of the rover that arrived at the purple planet in February final yr. The shroud is an element of a thermal blanket used to manage temperature and defend persistence throughout entry into the Martian ambiance.
NASA explains that the “thread” is a kind of polyester fiber that crumples and shreds after being subjected to “excessive forces.” No matter how a lot the object falls into the air – throughout the touchdown process – it’s seemingly that it is going to be carried away by the wind after falling to the floor.
Since the object didn’t reappear after two days, NASA concluded that it was mild sufficient to be simply carried in the air. It ought to be remembered that the touchdown web site of the rover – Jezero Crater – is consistently uncovered to gusts of wind. Even Perseverance had one of its climate sensors broken by a sandstorm.
The rover landed on Mars
To safely attain the floor of Mars, the car-sized Perseverance rover makes use of a posh touchdown system that features warmth shields, parachutes, retro-rockets and even a kind of crane, all working in a single place. robotically and autonomously. You can see the process in the video beneath:
After touchdown the Persistence on the floor, the system will take off to land at a protected distance from the rover.
Part of this touchdown system was captured by the Ingenuity spacecraft that arrived with the Mars Persistence in April. In the image beneath, you’ll be able to see that the gear broke into a number of small items when it hit the floor.
Although this particles is positioned lower than 1 km from the touchdown web site of the NASA rover, lighter elements equivalent to a bit of “aluminum foil” embedded between the rocks, in addition to a fibrous object, can recurrently fly off. .
According to NASA, smaller items of the touchdown system had been noticed about 2 kilometers from the crash web site. At least 6 copies had been cataloged.
Studying this particles is of curiosity to NASA as a result of understanding how these supplies behave throughout the touchdown process will assist enhance elements for future missions.
In addition, there are issues about the growing quantity of house particles on Mars, the potential for this materials to infect samples collected from Martian soil, and the chance of particles interfering with Persistence and disrupting its operation.
