The search for extraterrestrial life is about to get serious, as the U.S. space agency announced in a statement this week. NASA’s Transiting Exoplanet Survey Satellite (TESS) has completed all certifications and is currently undergoing final preparations for an April 16 launch aboard a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.

Initially slated for a two-year mission, TESS will ascend to an elliptical 13.7-day orbit around the Earth. It’s a unique and extreme orbit that’s never been used before, varying as close as 67,000 miles and as far away as 232,000 miles from its home planet. According to Space.com, the stable orbit will allow TESS to stay in space for decades without any need for course corrections.

Outfitted with four wide-angle cameras, TESS will be able to observe 85 percent of the surrounding sky as it looks for exoplanets. The instruments on the spacecraft will map 26 different “sectors” of the sky over a two-year period.
