This week we talk about Luna 2, soft-landings, and Firefly Aerospace.

We also discuss the private space launch industry, lunar landers, and regolith.

In 1959, Luna 2, a Soviet impactor-style spacecraft, successfully reached the surface of the Moon—the first-ever human-made object to do so.

Luna 2 was very of its era; a relatively simple device, similar in many ways to the better-known Sputnik satellite, but getting a craft to the moon is far more difficult than placing something in orbit around Earth, in part because of the distance involved—the Moon is about 30-Earth’s from the surface of the earth, that figure varying based on where in its elliptical orbit it is at the moment, but that’s a good average, around 239,000 miles which is about 384,000 km, while Sputnik’s orbit only took it something like 359 miles, around 578 km from the surface. That’s somewhere in the neighborhood of 670-times the distance.

So new considerations, like fuel to get there, but also charting paths to the moon that would allow the human-made object to actually hit it, rather than flying off into space, and even figuring out whether craft would need to be designed differently if they made it out of Earth’s magnetic field, were significant hurdles that had to be leapt to make this mission a success; everything was brand new, and there were gobs of unknowns.

That said, this craft didn’t settle onto the moon—it plowed into it like a bullet, a so-called ‘hard landing.’ Which was still an astonishing feet of research and engineering, as at this point in history most rockets were still blowing up before making it off the launch pad, including the projects that eventually led to the design and launch of Luna 2.

The US managed their own hard landing on the Moon in 1962, and it wasn’t until 1966 that the first soft landing—the craft slowing itself before impact, so that some kind of intact device would actually continue to exist and function on the surface of the moon—was accomplished by the Luna 9.

The Luna 9 used an ejectable capsule that was protected by airbags, which helped it survive its 34 mph, which is about 54 kmh impact. This successful mission returned the first panoramic photographs from the surface of the moon, which was another notable, historic, incredibly difficult at the time feat.

A series of rapid-fire firsts followed these initial visits, including the first-ever crewed flight to the Moon, made by the US Apollo 8 mission in 1968—that one didn’t land, but it did circle the Moon 10 times before returning to Earth, the first successful crewed mission to the surface of the Moon made by the Apollo 11 team in 1969, and by the early 70s humans had made several more moon landings: all of them were American missions, as the US is still the only country to have performed successful crewed missions to the Moon’s surface, but the Apollo 11, 12, 14, 15, 16, and 17 missions all put people on the lunar surface, and then returned them safely to Earth.

The Luna 24, another Soviet mission launched in 1976, was the last big space race era mission to return lunar samples—chunks of moon rock and regolith—to earth, though it was a robotic mission, no humans aboard. And by many measures, the space race actually ended the previous year, in 1975, when Apollo and Soyuz capsules, US and Soviet missions, respectively, docked in orbit, creating the first international space mission, and allowing US astronauts and Soviet cosmonauts to shake hands, symbolically burying the hatchet, at least in terms of that particular, non-earthbound rivalry.

What I’d like to talk about today is a recent, successful soft landing on the lunar surface that’s historic in nature, but also contemporarily significant for several other reasons.
