The booster destroyed Monday was slated to fly on the seventh launch of Firefly's Alpha rocket, an expendable, two-stage launch vehicle capable of placing a payload of a little over 2,200 pounds, or a metric ton, into low-Earth orbit. This upcoming launch was supposed to be the Alpha rocket's return to flight after an in-flight failure in April, when the upper stage's engine shut down before the rocket could reach orbit and deploy its satellite payload.
