NASA is preparing for a third attempt to launch its new rocket on September 27. NASA will conduct a separate test several days before the launch date to make sure the fixes have worked. We have everything you need to know about the test and how to watch it on the internet.

The test of the Space Launch System rocket will take place on September 21 at NASA's Kennedy Space Center in Florida.

Two previous attempts to launch the Space Launch System rocket have had issues with hydrogen leaks. The rocket uses a mixture of both liquid oxygen and liquid hydrogen as fuel, but getting the liquid hydrogen into the rocket's core stage has been problematic.

There was a small liquid hydrogen leak during the first attempt at launch, but the launch was called off due to engine issues. Several attempts to fix the leak were unsuccessful.

NASA engineers have repaired the hardware that was damaged by the leak. To try to avoid another leak issue, the tanking test will see the rocket's tanks filled with fuel to test out whether everything goes smoothly.

NASA says that the demonstration test will allow teams to confirm the repair to a hydrogen leak seen during an Artemis I launch attempt. When the objectives have been met, the demonstration will end.
