NASA's Artemis Program: Returning to the Moon and Preparing for Mars
TLDR NASA's Artemis program aims to return to the Moon by 2024 and establish a permanent base on the Moon's South Pole. The program will utilize the SLS rocket, the Orion space vehicle, and the lunar gateway to transport astronauts to the Moon, while also planning for manned missions to explore the Moon's surface and laying the groundwork for future missions to Mars.
Timestamped Summary
00:00
NASA is ready to return to the Moon with the ambitious and long-term Artemis program, after a 50-year hiatus since the Apollo program.
01:37
The idea of going back to the Moon has always been there, but the focus shifted to Mars; however, in order to go to Mars, we need to go back to the Moon first, and NASA's first attempt to return to the Moon with the Constellation Program was cancelled in 2010 due to budget issues.
03:05
The SLS rocket, which was originally intended for deep space missions and a potential return to the Moon, has been controversial due to its high cost and numerous delays, but it has now been given a purpose with the establishment of the Artemis program, which aims to return to the Moon by 2024 and eventually establish a permanent base on the Moon's South Pole.
04:28
The Artemis program will utilize the SLS rocket, the Orion space vehicle, and the lunar gateway to transport astronauts to the Moon, where they will rendezvous with the Starship Human Landing System.
05:52
The Starship Human Landing System will be much larger than the Apollo LEM, able to carry over 100 tons of equipment and be completely reusable, and there are plans for a modular lunar base design for astronauts to live full-time, while the Commercial Lunar Payload Services program will involve unmanned missions to explore the Moon's surface.
07:10
Artemis is planning for two different surface vehicles on the Moon: the Lunar Terrain Vehicle (LTV) for short-distance transportation, and the Lunar Cruiser for longer trips of up to 45 days, making it a more involved program than Apollo.
08:36
Artemis 4 is scheduled for 2027, and this will be the first use of the lunar gateway, while Artemis 5 through 11 are proposed missions that would take place between the years 2028 and 2032, with no set time frame for a Mars mission yet.
