Flying from Cape Canaveral in Florida, the Falcon 9 and its SpaceX Dragon capsule were successfully launched last Friday, April 18 at 3:25 pm or 1925 GMT to the International Space Station (ISS).
The SpaceX Dragon capsule separated from the second phase of the rocket around 10 minutes after it lifted off and before going into course. The launch marked its fourth visit to the ISS and the third trip of the capsule.
The spacecraft is carrying about 2.2 tons of supplies for the orbiting laboratory that consists of food, spacewalking gear, legs for the resident robot station, supplies, mating fruit flies, equipment and other supplies as needed by the astronauts. It also brought family care packages for the six space men.
At present, SpaceX has a $1.6B contract with NASA to send off the unmanned Dragon cargo ships to the ISS. The launch, according to SpaceX, amounted to about $5 billion including the commercial satellite owners' money and bookings.
