Weather forecasts point to excellent conditions for Relativity Space's third attempt at launching the world's first 3D-printed rocket, currently set for late Wednesday from Cape Canaveral Space Force Station.

Space Force forecasters on Monday said weather around Launch Complex 16 should be 90% "go" for liftoff of Terran 1, a 110-foot rocket slated to become the first launch ever for Relativity. A three-hour window to fly opens at 10 p.m. EDT.

"Expect only a few clouds to be in the area on Wednesday and as a result, the primary weather concern will be the cumulus cloud rule," Space Launch Delta 45 forecasters said Monday.

Conditions should be "go" for spectators, too: 68 degrees, 78% humidity, and mostly gentle winds.

Since this first flight is a demonstration mission, Terran 1 will fly without a customer payload in the fairing. Two previous attempts were scrubbed due to a mix of technical, weather, and range issues – not uncommon during a new rocket's debut attempt.

Terran 1 is 85% 3D printed by mass. After the hardware is produced in California, completed rocket stages are shipped to Cape Canaveral Space Force Station using semitrailers.

Relativity says 3D printing will be essential to long-term habitability in space and on the moon and Mars. Instead of waiting months or years for replacement parts to be shipped off to habitats, for example, astronauts will be able to print the necessary parts right there. The company's long-term goal, much like SpaceX, is to help establish human settlement on Mars.

Beyond Relativity, the Space Coast's next launch attempt appears to be set for the late morning of Friday, March 24: a SpaceX Falcon 9 rocket will boost the latest batch of Starlink internet satellites from the Cape's Launch Complex 40, then return for a drone ship for landing. SpaceX has not yet confirmed the existence of this mission, but federal filings point to a liftoff between 11:23 a.m. and 3:53 p.m. EDT Friday.

A Starlink weather forecast is expected Tuesday afternoon. For the latest, visit
