NASA launches ‘most powerful’ Moon rocket


NASA launched the most powerful rocket ever built on a journey to the Moon on Wednesday, in a spectacular blaze of light and sound that marked the start of the space agency’s new flagship program, Artemis. The 32-story tall Space Launch System (SLS) blasted off from the storied Kennedy Space Center in Florida at 01:47 am (0647 GMT), producing a record 8.8 million pounds (39 meganewtons) of thrust.

“What you have done today will inspire generations to come, thank you!” Charlie Blackwell-Thompson, NASA’s first female launch director, told cheering teammates. Fixed to the rocket’s top was the uncrewed Orion spaceship that will orbit Earth’s nearest neighbor, in a test run for later flights that should see the first woman and first person of color touch down on lunar soil by the mid-2020s. About two hours after launch, NASA said the spacecraft had completed a propulsive maneuver to escape the pull of Earth’s gravity and was on its path to the Moon.

“Trans-lunar injection burn complete! NASA Orion is on its way to the Moon!” tweeted Jim Free, NASA’s associate administrator for exploration systems. America last sent astronauts to the Moon during the Apollo era, from 1969-1972. This time it hopes to build a sustained presence — including a lunar space station — to help prepare for an eventual mission to Mars in the 2030s. There were nervous moments as teams worked to overcome technical issues that ate into the two-hour launch window, which opened at 1:04 am.

First, engineers were forced to pause the flow of liquid hydrogen into the core stage Tuesday night because of a valve leak, but a team sent to the launch pad resolved the issue after about an hour, by tightening loose bolts. Later, the space agency reported that a radar site monitoring the rocket’s flight path was experiencing problems due to a faulty Ethernet switch, which had to be replaced.
