The Mission

NASA | The Search for New Worlds is Here

The Transiting Exoplanet Survey Satellite (TESS) is an astrophysics Explorer-class mission between NASA and MIT.
 After launching in 2017, TESS will use four cameras to scan the entire sky, searching for planets 
 outside our Solar System, known as exoplanets. The mission will monitor over 500,000 of the brightest stars 
 in the sky, searching for dips in their brightness that would indicate a planet transiting across. 
 TESS is predicted to find over 3,000 exoplanet candidates, ranging from gas giants to small rocky planets.
 About 500 of these planets are expected to be similar to Earth's size.
 The stars TESS monitors will be 30-100 times brighter than those observed by Kepler,
 making follow-up observations much easier. Using TESS data, missions like the James Webb Space Telescope 
 can determine specific characteristics of these planets, including whether they could support life.

Farewell Kepler. Welcome TESS And The Quest To Find Earth 2.0

We’re now entering the final days for NASA’s Kepler Space Telescope. It’s running out of fuel and already crippled by the loss of its reaction wheels. In just a few months NASA will shut it down for good. That is sad, but don’t worry, NASA’s next planet hunting spacecraft, the Transiting Exoplanet Survey Telescope is on the launchpad and ready to fly to space to take over where Kepler left off. Finding Earth-sized worlds in the Milky Way.

How NASA’s Newest Planet Hunter Scans the Sky

TESS, the Transiting Exoplanet Survey Satellite, is NASA's newest exoplanet mission. Led by MIT, TESS will find thousands of new planets orbiting nearby stars. During its two year survey, TESS will watch a wide variety of stars, looking for signs of planets ranging from Earth-size to larger than Jupiter. Each of TESS's cameras has a 16.8-megapixel sensor covering a square 24 degrees wide — large enough to contain an entire constellation. TESS has four of these cameras arranged to view a long strip of the sky called an observation sector. TESS will watch each observation sector for about 27 days before rotating to the next. It will cover the southern sky in its first year, and then begin scanning the north. TESS will study 85 percent of the sky — an area 350 times greater than what NASA's Kepler mission first observed — making TESS the first exoplanet mission to survey nearly the entire sky. Because TESS's observation sectors overlap, it will have an area near the pole under constant observation. This region is easily monitored by the James Webb Space Telescope, which allows the two missions to work together to first find, and then carefully study exoplanets.

NASA’s TESS Catches a Comet

This video is compiled from a series of images taken on July 25 by the Transiting Exoplanet Survey Satellite. The angular extent of the widest field of view is six degrees. Visible in the images are the comet C/2018 N1, asteroids, variable stars, asteroids and reflected light from Mars. TESS is expected to find thousands of planets around other nearby stars.

#42 ON TRENDING The TESS Mission

SpaceX is targeting launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) on Wednesday, April 18 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The 30-second launch window opens at 6:51 p.m. EDT, or 22:51 UTC. TESS will be deployed into a highly elliptical orbit approximately 48 minutes after launch. Following stage separation, SpaceX will attempt to land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.

Now that TESS is Operational, Astronomers Estimate it’ll Find 14,000 Planets.
10 Could Be Earthlike Worlds in a Sunlike Star’s Habitable Zone

How many exoplanets are there? Not that long ago, we didn’t know if there were any. Then we detected a few around pulsars. Then the Kepler spacecraft was launched and it discovered a couple thousand more. Now NASA’s TESS (Transiting Exoplanet Survey Satellite) is operational, and a new study predicts its findings.

Kepler’s field of view encompassed only 0.25% of the sky. TESS will look at almost the entire sky. Image: NASA/Ames/JPL-Caltech, Image credit: Software Bisque
