The maiden flight of NASA’s Space Launch System, a heavy-lift human-rated rocket and one of the agency’s core programs, will likely not be ready for takeoff until 2020, officials said recently.

The first of up to 22 launches on Arianespace’s schedule in 2020 successfully delivered a commercial European broadband satellite and an Indian communications payload to orbit Thursday using a heavy-lift Ariane 5 rocket.

The Emirates Mars Mission, the first deep space probe from the Arab world, steered into orbit around the Red Planet on Tuesday to cap a 307 million-mile (494 million-kilometer), 205-day interplanetary voyage from Earth and begin a science mission studying the Martian climate. The critical 27-minute Mars Orbit Insertion maneuver began at 10:30 a.m. EST (1530 GMT).
