Orbital Science was set to launch its Cygnus cargo spacecraft on Thursday, but thick clouds and rain over its launch site in Florida forced Orbital ATK to postpone the launch until Friday, 4:33 p.m. EST.
But even the weather forecast for Friday is only 30 percent favorable for takeoff, NASA said, according to Yahoo News.
This is an important launch for Orbital after its failed launch in October of last year, when its Antares rocket exploded 15 seconds from launch, turning the cargo into a fireball and damaging Wallops Island's launchpad.
While the Antares rocket continues its recovery, the Cygnus cargo will be launched using a competitor's rocket - United Launch Alliance's Atlas V rocket, according to The New York Times.
Cygnus is on a mission to deliver 3,300 kiligrams (almost 6,614 pounds) of supplies to the International Space Station. This includes food, a jet pack for spacewalking astronauts, various science equipment and a satellite made by elementary students, according to Yahoo News.
It also includes a set of Microsoft Corp. HoloLens augmented-reality goggles to assist astronauts aboard the space station, according to Bloomberg.
It would take about three days for the cargo to reach the ISS, so if the weather permits the launch on Friday, astronauts in the ISS can expect their supplies by Monday.
