HOUSTON (CW39) Hundreds of people were lined up outside Space Center Houston when the doors opened at 5:15 Monday morning.

They all wanted to be the first people inside the watch party for the launch of Artemis I, NASA’s newest space mission.

A newly designed rocket system will propel the Orion capsule into the heavens.

Artemis I is an unmanned flight, but subsequent flights will take astronauts to the moon and beyond.

Watch partygoers toured exhibits, mingled with NASA mascots, and tested their luck in a raffle.

But the big attraction was the large video screen that was to show the launch.

Unfortunately for those in attendance, the launch was scrubbed because of a fuel leak and engine problems.

“It was definitely disappointing to hear that the flight’s been scrubbed,” partygoer and NASA employee Andrea Urueta. “We’ve been working so hard on this mission. This mission has taken years to even get to this point.”
