NASA troubleshooting Artemis II issue

NASA is troubleshooting an issue with the flight termination system (FTS), a critical safety component.

The FTS is designed to safely stop the rocket if it veers off its planned path, to protect people or property on the ground.

To help fix the issue, the team is bringing in a piece of hardware that was originally used on Space Shuttle missions.

Hatch seal check completed on Orion spacecraft

The closeout crew has completed its hatch seal check for the Orion crew module's side hatch, which allows them to watch for any loss of pressure over time or making sure the door is completely airtight.

Engineers are focusing on conducting a full cabin leak check before moving forward with closing the second hatch on the Orion spacecraft, which is the Launch Abort System hatch.

1 of 2 hatches closed on Orion spacecraft

The closeout crew has now closed the side hatch, one of two hatches on the Orion crew module. The remaining hatch that the team is working to close is the Launch Abort System hatch.

This comes after the space agency confirmed that the spacesuits of all four astronauts passed their leak checks while in the Orion module, which once again tested the suits' pressure, ensuring they are airtight.
