NASA's newest planet-hunting telescope is officially at work.
The Transiting Exoplanet Survey Satellite (TESS), which is designed to hunt for alien worlds around stars not too far from the sun, began gathering science data Wednesday (July 25), members of the instrument team announced yesterday (July 27).
TESS will send that initial data to Earth in August, with new observations arriving every 13.5 days after that, mission team members said in a statement.
"I'm thrilled that our planet hunter is ready to start combing the backyard of our solar system for new worlds," Paul Hertz, director of NASA's Astrophysics division, said in the statement. "With possibly more planets than stars in our universe, I look forward to the strange, fantastic worlds we're bound to discover."
TESS launched on April 18 into orbit around Earth and then underwent a period of testing to ensure the instrument was ready to use. It sent its first photograph, a test image, down to its handlers in May. That image showed 200,000 individual stars, many of which could be accompanied by at least one planet.
TESS follows in the footsteps of NASA's iconic Kepler telescope, which in the course of two missions has identified 2,650 confirmed exoplanets, according to the space agency. Like Kepler, TESS will look for tiny dips in the brightness of individual stars caused by a planet passing between its star and the telescope in its orbit.
But whereas Kepler was limited to poring over a small patch of sky during its primary mission, TESS will study almost all of the sky in its two planned years of observations. During that survey, it will focus on the 200,000 brightest stars in the sky which means the project should identify planets around many of the stars that skywatchers know and love.
The team that designed TESS has calculated that the instrument should spot about 1,600 new exoplanets, including some the size of Earth.
Some planets TESS spots will likely become targets for follow-up study by NASA's much-delayed James Webb Space Telescope, which will be able to study the atmospheres of those planets and begin characterizing them in more detail than TESS can manage.
These people watched too many scenes in the “Star Trek Lounge”.
alien life, eh?
well, chances are that Obama’s home planet is within reach of this nice new telescope

I recall getting flack years ago, when I mentioned this as a likely number and timeframe.
Here’s the one I was going to place beneath it, but didn’t dare.
Lots more info here...

Lets say we find one. What good will it do? We cant even get to the moon!
This should not be part of NASA’s budget priorities at this time. There are far, far too many more immediate and practical space exploration efforts that NASA’s tight budget should be prioritized on. We have likely a century, or maybe two before exploring worlds beyond our solar system will have any practical immediate scientific importance. It’s not a good use of taxpayers space explotation funds at this time.
If we find an inhabitable world, we will have a a goal to inspire people and something to work for. Without a planet to inspire us, we will waste our money on government bureaucracy and unnecessary welfare.
I think you were right.
It would be a great addition if FR had a “NSFW” tag.
“If we find an inhabitable world, we will have a a goal to inspire people and something to work for. Without a planet to inspire us, we will waste our money on government bureaucracy and unnecessary welfare.”
B.S. Thers is plenty of exploration to “inspire us” in our own solar system, and, as I said, a good 100-200 years before “inspiration” beyond this solar system will have practical human means to explore it. That will leave plenty of time before exploring the universe with long range observation craft will be needed. There are more important practical budgetary requirements now.
