  • The American space agency NASA postponed the launch of its new moon rocket on Monday because of an engine problem.
  • 2
  • The launch of NASA's Space Launch System, or SLS, was called off about 40 minutes before launch time at Kennedy Space Center in Cape Canaveral, Florida.
  • 3
  • NASA said on its website that the problem was linked to difficulties cooling the rocket's main engines to the needed temperature for liftoff.
  • 4
  • The agency said engineers were continuing to gather data and carry out tests on the engines.
  • 5
  • The next launch possibility has been set for Friday, September 2.
  • 6
  • NASA has described the 98-meter SLS as the most powerful rocket ever built.
  • 7
  • It is part of the agency's Artemis program, which aims to land the first woman and first person of color on the moon.
  • 8
  • Artemis seeks to land American astronauts on the moon no earlier than 2025.
  • 9
  • It would be the first moon landing by astronauts since NASA's Apollo 17 mission in 1972.
  • 10
  • Artemis also calls for establishing a long-term base on the moon that could one day launch astronauts to Mars.
  • 11
  • NASA is calling the first launch of the SLS rocket Artemis 1.
  • 12
  • The rocket will carry NASA's Orion spacecraft, or capsule, on a test mission to fly around the moon.
  • 13
  • There will be no astronauts on the spacecraft during the test flight.
  • 14
  • Instead, three mannequins will be placed inside the crew capsule.
  • 15
  • They will be connected to a series of sensors designed to measure radiation and movements during the mission.
  • 16
  • During the trip, Orion is expected to travel 450,600 kilometers from Earth and thousands of kilometers beyond the moon.
  • 17
  • NASA said this will be farther than any spacecraft built for humans has ever traveled.
  • 18
  • The mission is expected to last four to six weeks.
  • 19
  • The Associated Press reported NASA officials also discovered communication problems late Sunday involving the Orion spacecraft.
  • 20
  • The problem was causing a delay in communication lines between launch controllers and Orion.
  • 21
  • Officials said that problem was solved by Monday morning.
  • 22
  • The main purpose of the SLS mission is to test the system for a future flight that will include actual astronauts.
  • 23
  • NASA has said that if everything goes well with Artemis 1, a trip involving astronauts could be launched as soon as 2024.
  • 24
  • SLS has been under development for more than 10 years.
  • 25
  • It has experienced a series of costly production delays.
  • 26
  • Orion will take nearly a week to reach the moon, which is about 386,000 kilometers from Earth.
  • 27
  • After passing close to the moon, the capsule will enter a distant orbit with a far point of 61,000 kilometers.
  • 28
  • That will put Orion 450,000 kilometers from Earth.
  • 29
  • At the end of the mission, Orion is expected to hit the atmosphere at 40,000 kilometers per hour on its way to a parachute landing in the Pacific Ocean.
