A fresh load of supplies is headed for the International Space Station.
Russia launched its robotic Progress 87 cargo ship on a Valentine's Day delivery mission toward the International Space Station tonight (Feb. 14).
The freighter lifted off atop a Soyuz rocket from the Russian-run Baikonur Cosmodrome in Kazakhstan at 10:25 p.m. EST (0325 GMT and 8:25 a.m. on Feb. 15 local time in Baikonur).

Progress 87 is carrying about 3 tons of food, propellant and other supplies.
If all goes according to plan, the freighter will reach the orbiting lab early Saturday (Feb. 17), docking with the Russian Zvezda service module at 1:12 a.m. EST (0612 GMT). You can watch that rendezvous live here at Space.com, via NASA; coverage will begin at 12:30 a.m. EST (0530 GMT) on Saturday.
Progress is one of three robotic spacecraft that currently fly resupply missions to the ISS, along with Northrop Grumman's Cygnus vehicle and SpaceX's Cargo Dragon capsule.
Progress and Cygnus are expendable spacecraft, burning up in Earth's atmosphere when their time in orbit is done. But Dragon is designed to be reusable; it splashes down safely in the ocean under parachutes, which means it can bring science samples back down to Earth.
