This Scientific American article looks at how landings on Mars have gotten more and more precise, shrinking the “landing ellipse” from 300 km × 100 km (Viking) to 7.7 km × 6.6 km (Perseverance), which enables landings in places other than wide undifferentiated plains. Some locales will be still be off-limits for some time: “For instance, scientists cannot propose landing on high-altitude features such as Olympus Mons because the atmosphere overhead is too tenuous to sufficiently slow down a spacecraft. Regions with very rough terrain or steep slopes are also off-limits, even with [Terrain Relative Navigation]. Furthermore, features such as polar ice caps, canyons, lava tubes and sand dunes offer poor prospects for wheeled rovers and would require alternate forms of mobility.”
We marked the 50th anniversary of Apollo 11 last week, which means that the next step is to put all our moon-landing related nostalgia away until the next milestone anniversary, or until another of the remaining Apollo astronauts dies.1
If, on the other hand, all this attention has piqued your interest in the moon landings, the Apollo program, and the history of crewed spaceflight generally speaking, I have some suggestions as to what you should watch and read next. There are, of course, plenty of books and documentaries on this subject, but these will give you a general overview, with increasing levels of detail.
