Live coverage: Launch of Delta 4-Heavy aborted seconds before liftoff

Rocket Lab’s launch of NASA’s second pair of TROPICS hurricane research satellites, reassigned from Astra following a launch failure last year, has been rescheduled for Sunday after a delay due to unfavorable weather at the the company’s New Zealand spaceport.

A U.S. Army veteran of Operation Desert Storm, a Russian Air Force MiG-29 fighter pilot, and a former flight controller for Russia’s Mir space station arrived at the International Space Station on Friday, with a smooth docking aboard a Soyuz spaceship at 0952 GMT (5:52 a.m. EDT), two days after a successful launch from Kazakhstan.

Iran’s second try in less than a month to send a satellite into orbit apparently failed shortly after liftoff from a remote desert launch pad under daily surveillance from a fleet of commercial imaging spacecraft, according to U.S. government officials and independent analysts.
