SpaceX is about to hit another round-number milestone.

Elon Musk's company will launch its 30th contracted cargo mission to the International Space Station (ISS) for NASA on Thursday (March 21), if all goes according to plan.

A robotic SpaceX Dragon capsule is scheduled to lift off atop a Falcon 9 rocket Thursday at 4:55 p.m. EDT (2055 GMT) from Cape Canaveral Space Force Station in Florida. You'll be able to watch the action live here at, courtesy of NASA.

The mission, known as CRS-30 ("Commercial Resupply Services-30"), will arrive at the ISS on Saturday morning (March 23), delivering food, supplies, equipment and a variety of scientific experiments to the orbiting lab.

Among those investigations are studies of "plant metabolism in space and a set of new sensors for free-flying Astrobee robots to provide 3D-mapping capabilities," NASA officials wrote in an update on Friday afternoon (March 15).

"Other research includes a fluid physics study that could benefit solar cell technology and a university project from CSA (Canadian Space Agency) that will monitor sea ice and ocean conditions," they added.

CRS-30's Dragon will spend about a month attached to the ISS before coming back to Earth with a splashdown off the Florida coast. 

Dragon is the only robotic ISS cargo craft capable of coming down in one piece (and hauling science gear from the station to researchers here on Earth). The other two operational freighters, Russia's Progress vehicle and Northrop Grumman's Cygnus, are designed to burn up in Earth's atmosphere when their orbital time is up.
