Watch two new arrivals at the International Space Station

These photos show the 215-foot-tall Falcon 9 rocket and Crew Dragon spacecraft at launch pad 39A, ready for liftoff from Florida’s Space Coast on a critical test flight to the International Space Station.

A two-stage Northrop Grumman Antares rocket rolled out of its horizontal integration facility Monday for the mile-journey south to launch pad 0A at the Mid-Atlantic Regional Spaceport in Virginia, where liftoff on a space station resupply mission is scheduled for Wednesday.

Japan’s sixth HTV supply ship departed the International Space Station on Friday and headed for a destructive re-entry over the South Pacific with trash and disused batteries from the research lab, but engineers will first use the spacecraft for a pioneering experiment to investigate a new way to remove space junk from orbit.
