SpaceX is about to launch a rocket that will send a critically important new telescope that will be used in NASA’s growing search for exoplanets that could host life. The launch is set for Monday, April 16, and the payload will be sent into space on a Falcon 9 rocket after the company completed a static fire of the rocket last Wednesday at Cape Canaveral Air Force Station.

Meanwhile, NASA sealed the Transit Exoplanet Survey Satellite (TESS) into its payload fairing as the agency gets ready to put it on top of the rocket. TESS arrived back in February after being built and tested at Orbital ATK’s facility in Virginia, and the satellite will be able to search for signs of planets orbiting around 200,000 stars.

It is just a taste of the incredible satellite that is to come known as teh James Webb Telescope, which be able to investigate far deeper into space than mankind ever has. The telescope will be able to cover almost the entire sky, and could lead to tremendous breakthroughs in our understanding of our universe.

“NASA’s Transiting Exoplanet Survey Satellite, or TESS, is making strides toward its upcoming liftoff,” reads a NASA statement. “The planet-hunting spacecraft is slated to launch from Cape Canaveral Air Force Station’s Space Launch Complex 40 on Monday, April 16, aboard a SpaceX Falcon 9 rocket. Inside Kennedy Space Center’s Payload Hazardous Servicing Facility, the TESS spacecraft was sealed within the Falcon 9 payload fairing in preparation for its move to the launch pad.”
