Terran 1, world's first (mostly) 3D printed rocket, lifts off ... and fails to reach orbit
that Max Q describes the point at which the dynamic pressures and stresses on the rocket peak. Surviving Max Q means the 3d printed parts used to make Terran 1 are tough enough to withstand flight - but not the whole one it seems.
It's not clear why the rocket failed to reach orbit, however."Relativity will share further updates there once they have them," a spokesperson told. Meanwhile, the company tweeted its Good Luck Have Fun flight was"the biggest proof point for [its] novel additive manufacturing approach.""Today is a huge win, with many historic firsts. We also progressed through Main Engine Cutoff and Stage Separation.
Relativity Space cancelled the first try due to a glitch impacting the stage separation automation system. Engineers made a fix and tried again. But the second attempt was scrubbed in the last minute of its launch window because of stage 2 fuel pressure problems.Around 85 per cent of the rocket's mass is from 3D-printed parts. The craft's nine Aeon 1 engines, for example, feature printed parts in their combustion chambers, igniters, thrusters, turbopumps, and pressuring systems.
Terran 1 did not carry any payloads for its inaugural launch. The company plans to launch small satellite payloads of up to 1,250 kilograms to low-Earth orbit at altitudes of 500 kilometers . Relativity Space is also continuing work on its more advanced, fully reusable 3D-printed Terran R rocket and has inked a deal with OneWeb to send a network of satellites into space. The company hopes to make up to 95 per cent of its rockets in-house using 3D-printed components, and to complete construction of each in just 60 days. ®
