![]() The project cost some $23.8 billion, a total that drew some criticism for being over budget. To build it, NASA contracted several companies-Northrop Grumman worked on the boosters, Aerojet Rocketdyne built the engines, and Boeing built the rocket’s orange core stage. It stands at 32 stories tall and weighs nearly 6 million pounds. The SLS is the most powerful rocket ever built, period. The SLS rocket and Orion spacecraft sit on a mobile launcher in front of a full moon on June 14. What’s special about the mission’s rocket, called the Space Launch System? Navy ship that will recover the spacecraft. If it survives, Orion will splash down in the Pacific Ocean off the coast of San Diego, within view of a U.S. The craft and its heat shield will have to endure temperatures of 5,000 degrees Fahrenheit-a crucial part of this test mission, since NASA can’t artificially create these conditions on the ground, reports Gizmodo’s George Dvorsky. On October 10, the Orion spacecraft will make a roaring return to our atmosphere-it will be moving at 6.8 miles per second, the fastest reentry of any capsule built for humans. ![]() Then, it’ll fire its engines at just the right time to be propelled back toward Earth, with the aid of the moon’s gravity. The spacecraft will complete up to one and a half revolutions in lunar orbit, where it will set a record for the farthest any spacecraft that can carry a crew has traveled. As Orion flies toward the moon, a service module provided by the European Space Agency will course-correct as needed. The 42-day Artemis 1 mission will test the Orion spacecraft, a capsule that will orbit the moon and one day carry human crew members there. Once in the atmosphere, Orion will begin in Earth's orbit, then soar through space powered by the Interim Cryogenic Propulsion Stage (ICPS), a 45-foot long cylindrical system with one engine. As NASA’s massive Space Launch System (SLS) rocket sits on the launch pad ahead of this historic mission, here’s what you need to know about the program making headlines around the world. These measures will lay the groundwork for yet another first in the future: sending astronauts to Mars.īut before all that happens, the space agency has to test its equipment with the flight of Artemis 1, which will break records of its own. In addition, the Artemis program will establish the first long-term human presence on the moon, by putting a space station in orbit and constructing a base camp on the lunar surface. ![]() If all goes as scheduled, in 2025, these astronauts will become the first humans to step on the lunar regolith-or dusty moon soil-since Apollo 17’s Gene Cernan and Harrison Schmitt walked there in December 1972. Named for the Greek goddess Artemis, Apollo’s twin sister, this initiative will put the first woman and first person of color on the moon. NASA’s new moon program is poised to smash all kinds of records for human spaceflight. ![]() If NASA can resolve the rocket's current issue, the next possible launch dates for the space agency's Artemis 1 mission are in mid-October. NASA postponed the first launch of the Artemis 1 mission's Space Launch System rocket on August 29 due to a temperature problem with one of four liquid-fuel engines. This morning NASA called off its second attempt to launch its new moon rocket due to a leak in its hydrogen fuel line.
