SpaceX launches NASA’s new planet-hunting Satellite TESS(Transiting Exoplanet Survey Satellite)

The Transiting Exoplanet Survey Satellite is a for NASA’s , designed to search for exoplanets using the transit method in an 400 times larger than that covered by the mission.

The launch has been delayed more than once already: originally scheduled for March 20, it slipped to April 16 (Monday), then some minor issues pushed it to April 19, 2018 at 3:51 PM Pacific time. You can watch the launch below:

The technique it will use is fundamentally the same as that employed by NASA’s long-running and highly successful Kepler mission. When distant plants pass between us and their star, it causes a momentary decrease in that star’s brightness.

TESS will monitor thousands of stars simultaneously for such “transits,” watching a single section of sky for a month straight before moving on to another.

By two years, it will have imaged 85 percent of the sky; hundreds of times the area Kepler observed, and on completely different stars: brighter ones that should yield more data.

TESS, which is about the size of a small car, was launched on top of a SpaceX Falcon 9 rocket. SpaceX will attempt to recover the first stage of the rocket by having it land on a drone ship, and the nose cone will, get a gentle parachute-assisted in the Atlantic, where it too can be retrieved.
