The Dragon spaceship poised for launch Tuesday will carry more than 2.5 tons of equipment for the International Space Station’s six-person crew, making the first U.S. supply delivery to the orbiting research complex since the crash of an Antares cargo rocket in October.

The United Launch Alliance Delta 4 rocket, standing 206 feet tall and and weighing 720,000 pounds, unleashes 1.1 million pounds of thrust from its main engine and two side-mounted boosters at 12:52 a.m. EDT (0452 today to launch the GSSAP No. 3 and No. 4 satellites for the Geosynchronous Space Situational Awareness Program from Cape Canaveral.

An Indian LVM3 rocket lifted off at 11:30 p.m. EDT Saturday (0330 UTC Sunday) with 36 more OneWeb internet satellites. Once the new 36 satellites complete orbit-raising and commissioning, OneWeb will have 618 active satellites in its fleet, enough for global broadband service.
