Live coverage: European ocean survey satellite launches from Russia

A new communications spacecraft for Hispasat, a Spanish communications satellite operator, will get a boost from a Russian Proton rocket Monday toward an orbital position more than 22,000 miles above Earth.

The ExoMars Trace Gas Orbiter, a Russian-launched, European-built spacecraft that arrived at Mars in October, is starting to dip into the upper reaches of the red planet’s atmosphere in a year-long “aerobraking” campaign place the observatory in the right position to hunt for methane, an indicator of potential biological activity.

India’s first dedicated astronomical observatory lifted off at 0430 GMT (12:30 a.m. EDT) Monday aboard a Polar Satellite Launch Vehicle, riding into a 400-mile-high orbit to begin a five-year mission studying the births and deaths of stars.
