Astra schedules next launch attempt
Capitalism in space: The new smallsat rocket company Astra has completed its investigation of its launch failure on August 28th and scheduled its next launch attempt for no earlier than October 27th.
During liftoff, kerosene fuel and liquid oxygen both leaked from the propellant supply system adjacent to the rocket. This system is designed to quickly disconnect and seal when the rocket launches. When LV0006 lifted off, these leaked propellants mixed and became trapped beneath the interface between the rocket and the ground equipment.
These mixed propellants were subsequently ignited by the exhaust of the first stage engines, which caused an over-pressurization that severed the electrical connection which controls the fuel pump. This caused the shutdown of one Delphin on the first stage less than one second after liftoff.
The company has revised its system to prevent further leaks, and shifted the fuel lines so that even if there is a leak, the propellants can no longer mix.
