Speaking of next launch opportunities, Relativity announced it could reattempt to launch the Good Luck, Have Fun mission on Saturday, with the same launch window of 1:00 p.m. The reason for the scrub was out of bound temperatures in the second stage, and teams will work to fix the issue before the next launch opportunity.

However, the company seems to have a goal to not only launch the first 3D printed rocket but also win the race for the first methane-powered rocket to reach orbit. Overall we had a clean launch countdown yesterday except for one issue, which was propellant conditioning (reaching the required temperatures).Īs Relativity reached the end of the count, the technical issue that pushed the launch back eventually scrubbed the launch.
