Relativity not letting their first launch's failure to a reach obit stop them and they're going straight to their much larger Terran R design with a reusable 1st stage ala Falcon 9
Terran 1 - 898kg payload to LEO
Terran R - 23,500kg (reusable 1 stage) 33,500kg (expended 1st stage) to LEO
For comparison F9 17,200kg and 22,600kg respectively to LEO (wiki)
Looks like they want to fit in the ground between F9 and FH (64,000kg to LEO)
Oh, and they think they've narrowed down T1's 2nd stage's failure to an oxygen pump
