A technical (but not very technical) explanation of the persistent spacecraft landing on Mars

There has been a lot of excitement about the arrival of the Perseverance rover, our latest robotic planetary explorer, to Mars. Keen to capitalize on this excitement, NASA JPL has released a lot of information to satisfy the curiosity of the general public. But making these materials widely accessible also means leaving out many technical details. People who crave a little more can head to How NASA’s Tenacity landed on Mars: A space engineer detailed it in startling detail Posted by Jalopnik.

The NASA JPL public material illustrates the overall significance. Even the scientifically detailed portions were largely restricted to the intended audience of K-12 students. Sure, anyone wanting more details can find it online, but they quickly find themselves engulfed in high-tech papers that aeronautical engineers and planetary geologists have written for their peers. There is a gap between these two extremes, and these slots for writing precisely in that gap. author [Brian Kirby] He is our assistant aeronautical engineer who combined several technical references into one landing narrative, illustrated at a level roughly equivalent to undergraduate math and science courses.

We get more details on why the target landing site is both geologically interesting and technically treacherous, requiring the development of a new landing intelligence that will undoubtedly help future robotic and human explorers. The complex multi-step transition from orbit to surface is explained in terms of kinetic energy management. A wide range of problems are condensed into the list of numbers that helps us understand why, for example, a parachute was necessary but not sufficient to bring the rover to the roof.

Old enthusiasts know a lot of this information, but we all had to start somewhere. This is a good ramp for a new generation of space enthusiasts, and together, we look forward to continuing our perseverance with our long and exciting to-do list.
