But at 11:15, police got a 911 call that the station was unmanned.
Problems arise when there's not a human around to intervene, such as at unmanned tollbooths, train station ticket kiosks or self-serve gasoline pumps.
However, after the successful launch of an unmanned capsule to the station, followed by the successful manned launch, it appears that things are now back on track.
In August, a Soyuz failure on an unmanned mission to resupply the space station led to a six-week suspension of flights.
The scheduled trip comes just a little over four months after the project successfully completed a docking test by the unmanned private spacecraft with the International Space Station.

Moscow (CNN) -- The Russian space agency on Monday postponed the launch of a new manned mission to the International Space Station due to last week's accident in which an unmanned cargo craft was lost, the state news agency RIA Novosti reported.
The RQ-4A Global Hawk drone crashed during a routine training flight from Naval Air Station Patuxent River, according to Jamie Cosgrove, a spokeswoman for the Unmanned Aviation and Strike Weapons Program at the base.
Following the retirement of the American space shuttle in July, the Soyuz rocket is the only means of getting astronauts and cosmonauts to the ISS. August's failure saw manned flights stand down even longer than the six weeks for unmanned Soyuz rockets, and the hiatus put a severe strain on the operation of the space station.
