The sampling mechanism on NASA’s OSIRIS-REx spacecraft is stuffed with specimens captured from asteroid Bennu earlier this week — so full that some of the rocks are floating out into space.

A SpaceX Falcon 9 launcher boosted a 4.7-ton military-grade communications satellite for SES and the Luxembourg government toward a perch 22,300 miles over the equator following a spectacular late afternoon liftoff Tuesday from Florida’s Space Coast, clearing the last mission off the launch company’s manifest before the long-awaited debut of the massive Falcon Heavy rocket.

Closing out a 30-day mission, a SpaceX Dragon cargo capsule departed the International Space Station on Monday for a fiery trip back to Earth, culminating in re-entry back into the atmosphere and a parachute-assisted splashdown in the Pacific Ocean southwest of Los Angeles.
