With the arrival of the Cygnus spacecraft at the International Space Station the US now has two commercial suppliers to deliver cargo to the station. Since the retirement of the shuttle and before SpaceX and Orbital Sciences the US was reliant on International Partners Russia, ESA and Japan to deliver cargo.
There are now five cargo vehicles available for the station, Cygnus, Dragon, Progress, European ATV and Japanese HTV.
Below are some images of the Cygnus arriving at the station taken from the NASA LiveStream feed.
Now we just need for Boeing, SpaceX and Sierra Nevada Corporation (SNC) Space Systems to complete their commercial crew vehicles and for NASA to have the funds to allow these to progress to actual flights and the station will once again have multiple craft able to launch crews.
