Sean Bailey75 said:Right now, only Russia has a proven and established technique—not just technology, but actual physical vehicles capable of traveling into Space—for human missions, and China will have it soon too.
Sean Bailey75 said:For everyone else, it's just too expensive right now. It's actually cheaper for Americans to buy transport services from the Russians until Elon Musk gets those Kuznjecov rocket engines (bought from the Russians) fully operational and runs the full SpaceX program without rockets falling down.
Americans deal with internal organizational issues that result in space projects being buried under paperwork that costs more than the spacecraft themselves, and there isn't even a price cap on the vehicles.
SpaceX uses its own engines and they are planning to launch next month with an improved version of the Merlin 1D engine at full thrust (they’ve been avoiding full thrust until now just to be safe). That one Falcon 9 that crashed had a bracket failure due to a quality control oversight. They will fix that now that they know what happened, and the new rocket version includes safety upgrades addressing issues encountered during the Falcon 1 program.
It is possible you mixed them up with Orbital ATK, who actually use Russian engines on their Antares rockets. They also had a rocket crash while supplying the ISS, so they are working on improvements too. (A few days later, the VSS Enterprise crashed as well)
By the way, Antares rockets are outrageously expensive compared to the Falcon 9. An Antares costs about $300-400M but carries less payload and can't return anything to Earth since it's basically used as a trash incinerator. Meanwhile, the Falcon 9 is $150M and carries twice the payload while being able to return cargo to Earth.
The Russians themselves lost their Progress M-27M mission to supply the ISS, which launched right before the failed SpaceX mission. Everyone has had a rough time lately regarding launches.
Edit: I'll stop the off-topic comments too.
