A Northrop Grumman Antares rocket, upgraded to carry heavier payloads into orbit, lifted off Saturday from a launch pad on Virginia’s Eastern Shore with a Cygnus supply ship in pursuit of the International Space Station with fresh food, a collection of biological and technology demonstration experiments, a zero-g baking oven, and repair gear for an aging $2 billion particle physics experiment.

An unmanned cargo freighter carrying nearly four tons of supplies and science, launched and operated commercially for NASA, blasted off from Cape Canaveral on Tuesday atop an Atlas 5 rocket bound for the International Space Station.

A United Launch Alliance Atlas 5 rocket will boost NASA’s Tracking and Data Relay Satellite-M, or TDRS-M, into space from Cape Canaveral on Aug. 18 at 8:03 a.m. EDT (1203 GMT).
