The Space Launch System (SLS) of the Artemis program is not a twin of the Saturn V rockets used during the Apollo program. Before SLS launched, Cabana said: “With the solid rocket motors, I imagine it will be much more similar to a shuttle launch, but more impressive because SLS has five-segment solids, not four, and four main engines instead of three. It’s going to get up and go! Riding uphill in the shuttle, one had a phenomenal sense of speed and acceleration, going from 0 to 17,500 mph [28,000 km/h] in 8.5 minutes. I imagine spectators will see — and feel — it even more with SLS.”
Artemis 1 is the first mission in humanity’s effort to send humans back to the Moon for the first time since 1972. Named for Apollo’s twin sister, Artemis will span several missions. Artemis 1 is an uncrewed flight that is testing the technology needed to ferry astronauts to the Moon’s neighborhood. If all goes well, Artemis 2 is expected to send real astronauts around the Moon sometime around 2024. Next, NASA plans to land the first woman and the first person of color on the Moon during Artemis 3 in 2025 — although delays are likely, according to many observers.
Formally established in 2017, the Artemis program is intended to result in a long-term human presence on the Moon, as well as serve as a first step toward Mars. And with Artemis 1 now more than halfway through it's record-breaking journey, millions of space fans are eagerly looking forward to what the next few years have in store.
