Relativity Space hopes to live additively ever after with Wednesday’s launch

Relativity Space, the ambitious company that aims to additively manufacture the majority of its rockets, will try again to make the debut launch of its Terran 1 vehicle on Wednesday evening from Florida.

The California-based company has a three-hour launch window that opens at 10 pm local time at Cape Canaveral Space Force Station (02:00 UTC on Thursday). The current forecast for the launch attempt is splendid, with a 95 percent chance of acceptable conditions, according to the US Space Force officials operating the range.

If recent history is any guide, Wednesday's launch attempt may consume most of the three-hour window. Relativity's first attempt to launch Terran 1, on March 8, was scrubbed near the end of the window due to problems with a fuel-temperature sensor on the second stage. A second attempt three days later did not get off the ground due to an array of issues, including last-second aborts, weather concerns, and a boat in the protected area around the launch site.
