NASA is once again counting down to launch its unmanned test flight Artemis I, which sets the stage for humanity’s return to the moon. Saturday marks NASA’s second attempt after Monday’s launch was canceled.

“There is no guarantee that we will disembark on Saturday, but we will try,” said Mike Sarafin, head of the Artemis mission, during a press conference on Thursday 1 September.

If the Space Launch System (SLS) rocket successfully launches, fires its Orion spacecraft around the moon, and the spaceship survives the fiery plummet through Earth’s atmosphere, NASA may be well on its way to putting its boots on. lunar surface in 2025, the first human moon landing since 1972. Eventually, NASA plans to build a permanent base on the moon and mineral resources there, before sending astronauts to Mars.

The rocket is located on Kennedy Space Center’s Launchpad 39B. It was originally supposed to take off on Monday, August 29, but during the countdown, engine problems emerged that delayed the launch. After fixing these issues, NASA says its next launch attempt will be Saturday, September 3, during a two-hour window opening at 2:17 PM ET.

Watch the launch live on NASA’s broadcast below, starting when technicians begin filling the rocket with fuel at 5:45 am ET. NASA plans to continue broadcasting until approximately 11:15 pm, when the Orion spacecraft retransmits its first images of Earth.

A backup window is also available on Monday 5th September, in case of last minute technical problems or weather delays. According to the Space Coast Tourism Bureau, more than 400,000 visitors are expected to gather near NASA’s Kennedy Space Center in Cape Canaveral, Florida on Saturday to witness the inaugural launch.

In an effort to bring astronauts back to the lunar surface for the first time since 1972, it took NASA 17 years and about $ 50 billion to develop the SLS rocket and its Orion spacecraft, according to The Planetary Society.

The bright new SLS rocket is taller than the Statue of Liberty, at 23 stories, with the spaceship secured on top. Four car-sized engines and two rocket thrusters should give it enough thrust to propel itself through the thickest parts of the atmosphere. If all goes smoothly, Orion will mark a total distance of approximately 1.3 million miles in 37 days. It will soar up to 60 miles above the lunar surface, allowing lunar gravity to carry it 40,000 miles beyond the moon before returning to Earth for a splashdown in the Pacific Ocean in October.

Scientists will assess how future astronauts will experience the stress of space by measuring the amount of cosmic radiation that the mannequins aboard the Orion capsule endured during the test flight. The mission will also launch several CubeSats, or miniature satellites, with science missions.

However, NASA’s primary goal with Artemis I is to test every function of the launch and spaceflight system, including Orion’s communications and navigation systems and its heat shield, which must withstand a fiery dip through the atmosphere. terrestrial at 25,000 miles per hour at temperatures reaching 5,000 degrees. Fahrenheit – before risking lives on future missions.

If the unmanned Orion spacecraft manages to circle the moon and back smoothly, the Artemis II mission will transport the astronauts on a similar roundabout. The Artemis III mission aims to get humans to the moon in 2025.
