San Francisco, 19 April, 2018 (Wire news) --  A NASA satellite has embarked on a quest for planets where life might exist.

Propelled by a Falcon 9 rocket supplied by private firm SpaceX, the Transiting Exoplanet Survey Satellite (TESS) hurtled off of a launchpad in Cape Canaveral, Florida and into its search for so-called “exoplanets”, or worlds capable of potentially supporting life.

The launch followed a two-day delay for additional testing on guidance and navigation systems.

TESS will watch for flickers of starlight emitted when planets pass in front of stars they orbit as scientists hope to catalogue thousands of new planets. They expect to discover hundreds of new exoplanets within that larger set.

It was the latest successful launch for SpaceX, a company founded by Tesla CEO Elon Musk that has in recent months deployed a fleet of communications satellites and hurled the world’s most powerful rocket into space.

In addition to sending TESS into space, SpaceX caught a tumbling rocket component in a seaborne vessel.
