European engineers who developed a small satellite hitching a ride to the International Space Station aboard a SpaceX supply ship Monday are gearing up for a first-of-a-kind experiment to examine ways to snare a chunk of space junk and tug it back to Earth.

India debuted a new configuration of its workhorse Polar Satellite Launch Vehicle, featuring four strap-on boosters and an upper stage with solar arrays to generate electrical power, with a liftoff at 0357 GMT Monday (11:57 p.m. EDT Sunday). The mission lofted an Indian military satellite and 28 nanosatellites for companies in the United States, Lithuania, Spain and Switzerland.

SpaceX has postponed Wednesday’s scheduled launch from California’s Central Coast with 64 smallsats, electing to keep the Falcon 9 rocket on the ground until at least Sunday to wait for improved weather conditions.
