NASA‘s Artemis II mission will rapidly ship astronauts on a day out around the moon, if the contemporary plans withhold. But why is the U.S. so eager to revisit the moon for the first time in additional than 50 years?
NASA has promised that returning to the moon will lead to original scientific discoveries, carry economic benefits, and inspire a original generation of explorers. It’s also no secret that China threatens to overtake the U.S. as the leader in space exploration, and the U.S. would no longer want to fall at the back of.

The moon and Earth are savor twins that have been dancing around each other since the starting up of the solar design around 4.5 billion years ago, said Sara Russell, a planetary scientist at the Natural History Museum in London. This means they have a shared history of impacts from asteroids, comets and other objects,
“It just has this 4-and-a-half-billion-year record of what has happened on its surface,” Russell told Are residing Science. “We can see how affected it has been by impacts, which have also happened to the Earth, but we don’t see evidence for that on the Earth so easily.”
Biological processes and weather-fueled erosion obscure Earth’s impact history. The moon, on the other hand, has a thin atmosphere, no weather and no life, so its impact craters can be preserved almost indefinitely. These conditions also provide other research opportunities.
“It’s kind of a great laboratory about what happens to geology if there isn’t any water or air,” Russell said. “We can understand these very fundamental [geological] processes much more easily in many cases by looking at them on the moon.”

Artemis II is the 2nd of five initial missions in the Artemis program, which aims to establish a long-term U.S. presence on the moon for the first time. The inaugural Artemis mission, Artemis I, was an uncrewed 26-day flight around the moon in 2022. Artemis II is the first crewed spaceflight in the program and is scheduled to ship four astronauts on a 10-day flight around the moon and back to Earth as rapidly as April 1.
Each Artemis mission is meant to acquire on its predecessor. Artemis I laid the groundwork for Artemis II, and Artemis II is about checking out methods ahead of Artemis III, Artemis IV and Artemis V. The latter two missions aim to build astronauts on the lunar surface in 2028, with Artemis V laying the foundation for what NASA claims will likely be a permanent lunar base.
NASA famously took 12 astronauts to the lunar surface as part of the Apollo missions between 1969 and 1972. Russell illustrious that lunar samples aloof all by the Apollo missions have saved scientists busy for more than 50 years, but the Apollo astronauts explored excellent a few of the lunar surface on the near facet of the moon, and excellent its equatorial space.
“It’s sort of like having several expeditions to the Sahara Desert and saying, OK, now we understand the Earth,” Russell said. “That’s why it’s important to go back to the moon and, particularly, go to different areas. This is where Artemis is really exciting. The future Artemis mission will go to the lunar south pole, which is an area that really hasn’t been explored before.”

The moon’s south pole is a prime location for water ice, which is thought to be concentrated in the polar areas of the lunar surface. Learning this water ice offers scientists with an opportunity to learn more about Earth’s history with water.
“We want to know how the moon got that water, and the reason we want to know that is because how the moon got its water is probably how the Earth got its water,” Russell said.
Traveling to the moon with a crew will also enable mission scientists to pursue another, perhaps more disturbing, goal of the Artemis program — investigating the effects of space travel on human physiology. The Artemis II flight is an opportunity for original studies of astronaut health, together with how space travel influences the body, mind and behavior, and how those impacts may affect future missions, according to NASA. This is one in all many ways the lunar missions are potential stepping stones to deeper space exploration.
That’s because the Artemis program is meant to advance applied sciences and fabricate infrastructure that will likely be necessary for sending astronauts to Mars. Space exploration is complicated, dangerous and costly, so NASA needs to take a look at its methods and its astronauts on the moon before sending them to farther destinations. Establishing a lunar base can be key to traveling to Mars.

The moon has assets that may detached make space more accessible. For example, NASA has claimed that if it can harvest the moon’s water, the space agency can exhaust it to befriend make ingesting water, oxygen and rocket gasoline — although this remains unproven. Taking pictures for the moon fulfills a broader strategy to get and exhaust assets off Earth,
