Atlas 5 launches AEHF 5 as seen from Kennedy Space Center (members only)

SpaceX’s Falcon 9 rocket got within a second of liftoff Sunday before a low-thrust alarm triggered an automatic abort. Watch a view of the dramatic last-second countdown cutoff at engine ignition from our camera at the launch pad.

SpaceX’s next Falcon Heavy mission, set for April 18 from NASA’s Kennedy Space Center in Florida, will launch a powerhouse bus-sized broadband satellite for Viasat into a high-altitude circular geostationary orbit, a demanding flight profile that will require disposal of all three of the rocket’s reusable boosters.

Rocket Lab successfully launched five small satellites from New Zealand Saturday for customers in the United States and Australia, including a CubeSat with a novel swarm of tiny magnetometers to measure the plasma currents that shape colorful auroras.
