The opening for commercial resupply to the ISS started with the COTS (Commercial Orbital Transportation Services) program which was announced by NASA in January 2006, while Bush was president. SpaceX and a company called Rocketplane Kistler (RpK) were given development contracts that same year. RpK never went anywhere and that contract was cancelled. They were replaced by another company called Orbital Sciences Corporation* in 2008. Both SpaceX and Orbital were given resupply contract in December 2008, the month before Obama took office.

It made total sense for the Obama administration & NASA to continue the process when they took over and expand it to the Commercial Crew Program. Hopefully Boeing will get their act together and they'll be taking crew to and fro from next year too.

[* Through merger, Orbital later became known as Orbital ATK, which was bought out by Northrop Grumman in 2018 and is now known as Northrop Grumman Space Systems. Their Cygnus spacecraft still does supply runs to the ISS and they were recently awarded a contract to supply the eventual Lunar Gateway as well.]

Commercial corporations have been an integral part of the US space programme since before there was a space programme. NASA has never built a rocket or spacecraft ever. The difference with the Commercial Crew Programme is that the design of the spacecraft was left to the individual companies rather than have NASA set out the exact requirements.

NASA then reviewed and selected from the various designs offered.

The seeds for what became the Commercial Crew Programme may pre-date Obama - but the programme was formally launched in 2011, three years into his Presidential term..

Yet another merger/takeover in the aerospace industry.

This has been one of the biggest problems with this sector over the past 50 odd years - the gradual reduction in competing entities bidding for contracts.

Kinda funny that Boeing & Lockheed were basically forced to collaborate (forming ULA) in an effort to stop the endless industrial espionage and other shenanigans they were up to with each other.

And effectively created a monopoly - only challenged in more recent years by the new kids on the block - at last.

Rocketdyne has changed hands a few times since they were set up as separate division of North American back in 1955.

Funnily enough they were owned by Boeing from 1996–2005, when they were sold off to Pratt & Whitney for a few years.

And Boeing and Pratt and Whitney were both once subsidiaries of a group known as The United Aircraft Corporation which also owned (no surprise here) United Airlines.

Fail. TVC issue apparently - Thrust Vector Control - engine gimbal system.

Their "expert", Alex, is painful to listen too. You know? you know? you know?

Commentator waffled on about how it will now be taken to KSC for stacking - obviously her script didn't include this scenario and she doesn't know a successful full duration run is required

There will be a press conference in a couple of hours so that will give us some idea as to where they go next. I’d be very surprised if they don’t run this test again before shipping the whole lot to Kennedy.
