A year after a launch mishap left Orbital ATK’s Cygnus supply ship without a ride to the International Space Station, company officials say the cargo delivery system is on the verge of a comeback, thanks to deals with United Launch Alliance and a decision to redesign its Antares booster with new rocket engines.

A Russian-made Soyuz rocket was launched from Europe’s space base in French Guiana on Monday at 2102 GMT (6:02 p.m. local; 5:02 p.m. EDT) with the Sentinel 1B environmental satellite.

An experimental receiver aboard a European satellite has picked up signals from more than 15,000 aircraft in the last two years, paving the way for future missions that could track global commercial air traffic from space.
