Photos: Atlas 5 rocket aims for International Space Station

A $110 million NASA science instrument twice targeted for cancellation by the Trump administration is set for launch Tuesday inside the trunk of a SpaceX Dragon cargo capsule for delivery to the International Space Station, where it will spend three years charting changing carbon dioxide concentrations in Earth’s atmosphere.

The first launch of Orbital ATK’s redesigned Antares rocket since an engine failure doomed a mission in 2014 will likely be delayed more than one month until August to complete analysis of data acquired during a first stage hotfire test, officials said.
