- 3991 - ARTEMIS SPACE MISSION - humans on the moon? Artemis 2 will be the first mission to carry humans to the moon's vicinity since 1972. Artemis 2 is the second scheduled flight of the Artemis program and the first crewed Artemis mission.
----------- 3991 - ARTEMIS SPACE MISSION - humans on the moon?
- During Artemis 2, four astronauts,
commander Reid Wiseman, pilot Victor Glover and mission specialists Christina
Koch and Jeremy Hansen will fly around the moon before returning to Earth. The
roughly 10-day-long mission is tentatively scheduled to launch in November
2024.
-
- Artemis 2 will use the huge “Space Launch
System” (SLS) megarocket and Orion spacecraft to launch the crew on the lunar
flyby mission. The astronauts and mission controllers will collect data on
Orion and the crew's performance to assess how ready the Artemis program is to
send people to the moon's surface.
-
- NASA successfully launched Artemis 1 on
November 16, 2021, from NASA's Kennedy Space Center in Florida. The mission
collected radiation data and engineering data to assess the SLS and Orion
spacecraft's readiness to carry humans.
-
- The crewed Artemis 2 mission requires new
spacesuits that are built to endure the cislunar environment, which has more
radiation than inside low Earth orbit where astronauts receive more protection.
-
- Artemis 2 will be the first major test of
the SLS and Orion spacecraft systems with humans on board. The mission will aim
to hit four major metrics of readiness,
mission planning, system performance, crew interfaces and guidance and
navigation systems.
-
- The mission path will see Orion take an
orbit around Earth known as "hybrid free return," which will see the
spacecraft orbit Earth twice to pick up speed for the trans-lunar
injection. Orion will then swing around
the moon on a "free-return trajectory" to make a direct return back
to our planet.
-
- The mission is expected to last between
eight and 10 days, but may be extended to as many as three weeks depending on
the mission objectives. The four astronauts on board Artemis 2 will be the
furthest people to fly from Earth after 1970's Apollo 13, assuming the new
mission reaches its expected maximum altitude of 5,523 miles above the moon's
surface.
-
- The mission will need to achieve the
following milestones:
-
- Launch from NASA's Kennedy Space Center's
Launch Pad 39B to low-Earth orbit.
-
- A maneuver in Earth orbit to raise the
perigee, or the lowest point of the orbit, roughly 40 minutes after liftoff.
This will be performed with the SLS “Interim Cryogenic Propulsion Stage”
(ICPS).
-
- A burn to raise the apogee, or highest part
of the orbit, again using the ICPS.
-
- A system check at 42 hours after the
mission begins to ensure the orbit is correct, ranging from 112 miles at the
closest point to Earth and 1,616 miles at its highest point.
-
- The ICPS will be disposed and Orion will do
a translunar injection to fly to the moon. The trip to the moon will take four
days and have a maximum altitude of 5,523 miles above the moon's surface.
-
- The spacecraft will return home. Once the
spacecraft is close to Earth, the crew module will separate from the European
Service Module and the crew module adapter, allowing for splashdown in the
Pacific Ocean.
-
- Investigators working with Artemis 2 will
spend several months at the least analyzing data. The next mission in line is a
landing mission called “Artemis 3”, which will land on the surface of the moon
in 2025 if all goes to plan.
-
- Assuming Artemis 3 lands on the surface in
2025, that will be the first landing mission by humans since NASA's Apollo 17
in 1972.
