The new Moon mission, explained (in 1 minute) | Howtown

The Gist

NASA’s Artemis 2 mission sends four astronauts in an Orion spacecraft on a four-day journey around the far side of the moon and back to a splashdown off the coast of San Diego, serving as a practice run for returning humans to the lunar surface.

Quick Overview

Artemis 2 carries four astronauts aboard the Orion spacecraft on a nominal lunar flyby trajectory to test systems and pave the way for future human moon landings. The mission begins with a launch from Florida, utilizes booster and core stage separations, performs maneuvers in Earth orbit, loops around the far side of the moon, and concludes with a Pacific Ocean splashdown.

Key Points: Artemis 2 carries four human astronauts inside the Orion spacecraft, which provides a living space comparable to a small camper. The launch takes place in Florida because the rotation speed near the equator gives the rocket an eastward velocity boost of 409 meters per second. The launch vehicle consists of 2,600 tons of metal and fuel that lift straight up before leaning east toward orbit. The solid rocket boosters separate into the Atlantic Ocean after a couple of minutes, followed shortly by the core stage separation. Orion achieves a speed of 8,000 meters per second before boosting into a wider orbit to practice maneuvers and deploy satellites. The journey to the moon takes approximately four days after the spacecraft uses its engines to break out of Earth orbit. The crew loops around the far side of the moon, setting a record for the farthest distance a human has ever traveled from Earth. The mission ends with a spacecraft splashdown off the coast of San Diego, acting as a crucial practice run for future crewed lunar landings.

Context: Humanity has not returned to the moon in decades, and questions about the origins of the moon remain partially unresolved. NASA's Artemis program aims to establish sustainable exploration on the lunar surface, with Artemis 2 serving as the critical first crewed flight test of the Orion spacecraft and Space Launch System rocket.
