SpaceX is working towards getting the Falcon 9 Block 5 certified for launching astronauts for NASA. SpaceX has built the crew Dragon space capsule. They still need to add new helium tanks to the Block 5. The Block 5 has been launched without the helium tanks. The first seven qualification launches will start next month or the month after with the Demo-1 flight to the space station.
The new helium bottles are composite overwrapped pressure vessels (COPVs). They store cold helium at high pressures for injection into the rocket’s propellant tanks. Various redesigns were needed for handling the frozen helium and liquid oxygen because of SpaceX accidents.
Helium One are an independent specialist explorer focussed on delineating and developing globally significant helium assets in Tanzania. In March 2017, Solo Oil Plc (LON:SOLO) acquired a 10% interest in Helium One Limited.
