Welcome to Edition 8.31 of the Rocket Report! We have some late-breaking news this week with an update Thursday afternoon from Rocket Lab on the timing of its much-anticipated Neutron rocket. Following the failure of a first stage tank during testing, the company is pushing the medium-lift rocket's debut into the fourth quarter of this year. Effectively that probably means 2027 for the booster, which is disappointing because we all very much want to see another reusable rocket take flight.
