DATA POINTS TO A ‘LARGE BREACH IN THE CRYOGENIC HELIUM SYSTEM’
Helium is typically used to pressurize the oxygen and kerosene rocket fuels. It’s stored at very high pressures, says Paulo Lozano, an aerospace engineer at MIT, but exactly how a breach would lead to the explosion is hard to say at this point.
The cause of the breach remains unknown as well. The investigation continues.
