- NASA’s Transiting Exoplanet Survey Satellite (TESS) will find undiscovered worlds around bright nearby stars, providing targets where future studies will assess their capacity to harbor life. TESS is a NASA Astrophysics Explorer mission, led and operated by MIT and managed by Goddard. With the help of a gravitational assist from the Moon, the spacecraft will settle into a 13.7-day orbit around Earth.
Four wide-field cameras will give TESS a field-of-view that covers 85 percent of the entire sky. Within this vast visual perspective, the sky has been divided into 26 sectors that TESS will observe one by one. The first year of observations will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.
The spacecraft will be looking for a phenomenon known as a transit, where a planet passes in front of its star, causing a periodic and regular dip in the star’s brightness. NASA’s Kepler spacecraft used the same method to spot more than 2,600 confirmed exoplanets, most of them orbiting faint stars 300 to 3,000 light-years away
TESS will concentrate on stars less than 300 light-years away and 30 to 100 times brighter than Kepler’s targets. The brightness of these target stars will allow researchers to use spectroscopy, the study of the absorption and emission of light, to determine a planet’s mass, density and atmospheric composition. Water and other key molecules in its atmosphere can give us hints about a planet's capacity to harbor life.

Great highlight video - Thank you for sharing NASA Goddard - looking forward to the results
Great Job Nasa...
Iam a commerce student .. but I love science so much .. i love space missions ... love you all scientists around the globe . You ppl are awesome
If TESS doesn't stare at the same patch of sky, How can it find planets that are far from its sun with long period of revolution?
Im looking forward to this mission
Excited now that it's finally operational. Can't wait to hear about anything lurking nearby, especially in Alpha Centauri!
inspiring
Amazing...
*CAN'T WAIT !*
The Exoplanets Channel I can't wait either #
Well, it's up there now ;)
You can wait and you will wait. And you will do so patiently.
The Exoplanets Channel you again man i find you every were
Edward Kasimir its already got lunched
Magnificant Achievement! I am in awe of such wonderful technology!
Go NASA GO!!
BEST OF LUCK NASA..my best wishes from the core of my heart is with you..
Wow 😍
It's about time, I thought there was a program on this long ago you just didn't want to talk about. We're all eager to know who else is out there and maybe want to make the Universe disputable to us.
Hopefully this has some extreme zooming capabilities and it doesn't get delayed like jwst constantly does.
Scheduled to launch in a few hours.... fingers crossed
Launching April 16, 2018!
yeah but then we ll have to wait months to find out what happens .
Some just can't get satisfied and find problems no matter what..
I know, someone might be happy and excited for five seconds. Can't have that.
It's so exciting!!! and they're using a Falcon 9! x2
that's awesome!!!!
73,000
Today i am very excited
If it transmit to earth if its near then how it would know about the other planets in the period of time?
Have a Good Journey TESS.
what happens if the planet is not crossing the star at the time the camera is pointing to it 27 days is not that long? Also, what if the orbit of the planet is going diagonal and the camera is pointed horizontal?
Interesting! In my opinion is very important TESS' activities. We're only in the Universe?
Why don’t the mirrors get dusty or dirty over time? Is there nothing floating around in space that could attach to the instruments and foul them up?
This is not the proper answer but it's somewhat related. It's about lenses on rovers on Mars getting dusty and how big of an issue is that - turns out it's not really that much of an issue. You can make an analogy between Mars atmosphere and the winds there carrying dust to outer space where there is barely any dust just floating around:

Ok Tess what are you seeing right now?!
❤️❤️❤️ NASA 🇧🇷
0:33 almost looks like Universe Sandbox 2
and 0:46
This plus James Webb will vastly increase our knowledge of the cosmos.
why only 16.8 Megapixel? i think my phone has that, i would have thought they could have gigapixels by now?
The video says TESS will collaborate with James Webb Telescope, but James Webb Telescope got delayed and will probably launch in 2020. The mission duration of TESS is two years, that means two telescopes actually will not be able to cooperate with each other...
Howard Stern as Ambassador for planet earth . I have long thought about this planetary formation around Vega in 1984 the pulsar planets 1992 Kepler 186 2014 .
cool
Tess Super Mega Fantastic Over the Top in the Space Forever !!!
We can't travel 100 light years but how it discover form so far.
Wowie
137 light years away
Nasa "benefit for all"
If Tess is male it is an hunter, if female an huntress.!!!
Exo planet has been located EXO-L home
WEBB hasn't been launced yet. The date of the WEBB launching is continuously moved ahead. Will it be the same with TESS?
shut the fuck up claudio, you're on every comment thread with the same bullshit.
Can it also detect NEOs?
John Johansen there's a project called "Sentinel" that is in the public NGO sector looking at launching a satellite to detect near earth objects. If you google sentinel & near earth objects you will probably find the relevant Wikipedia page. Good luck. :)
why is every camera only 16.8 megapixels?
Because 41 megapixels is overkill
Idunnohuur why? Won't you have more details?
Saad Jamal
More megapixels doesn't mean a better picture. Resolution and aperture are also needed for a better picture.
NASA! pls i love pluto planet pls
They're using the same method of detecting planets for 25 years
Mohammad Sufian because it works so well and we are getting better and better sensors
Claudio you are a moron.
Hello World!
I want to admit NASA please reply
But what about the remaining 15% ??
Mystery Man Kepler already did that 15% left
Abdelmouttaleb Azeddine most of the 15%*
They're trying to cover as much area as they can for a 2 year budget window but TESS can potentially stay up for 18 years, which is plenty of time to cover the rest, as well as revisit areas deemed interesting.
Please nasa name this star shot probe change name super nova star shot probe 212!!😊
Our beloved Space scientists are on the way to find earthlike planet.
I wish I could get the answer Are we alone?TESS will answer us.
When we think space our shrinking mind rises as space.Clash and war ends.
Expecting a lot from our space scientists.
Still looking for Planet X hahhahahahhahaaaa
3 kinds of knowledge .
1. Gods
3. we .
in between are the scientists .
only 16.8 mega pixels?
some cell phones have a better camera than that.
i'm disappointed
Even if it hasn't as many pixels, these cameras are easily better than any smartphone camera.
Lol megapixels is almost just a marketing term. It's all about the lens baby.
eventually the image has to land on pixels.
and if you have only a few pixels, your resolution is limited no matter what lens you have.
at the end of the day smartphones don't come even close to NASA cameras, their cameras cost millions while smartphone camera cost probably 60$ to manufacture. why do you thing lenses cost almost more than camera itself?
FYI - The Hubble Space telescope has a 16.8 mega pixel camera.
This satellite will have 4 of those.
It's 4 Hubble space telescopes, packed into one.
Quit your whining.
Why doesn't NASA take advantage of one of its super-telescopes sent to explore space to take an entire unmounted photo of the earth to get rid of this issue of terraplanists questioning the shape of the earth, since there is none of the kind, that would be an irrefutable way to prove the current shape of the earth and solar system.
Because NASA has better things to do than use valuable observation time from their telescopes to disprove idiots
Good, but the technology is the same, no jump in progress. Why dont u build abservatory on the moon ?
Key, it is still more advanced than the Kepler mission. Also, an observatory on the moon would be prohibitively expensive. We have giant new observatories under construction on earth that can do the same thing.
2nd and I know it's real I believe NASA
:)
Do you really think that if they found anything they would tell us ? Most likely not, ya take our tax money and run with it.
Oh and where is the video from the rovers on Mars today as of 3/2019, we all have phones that take both video and still pictures and yet a billion dollar camera on each rover does not take video, ya right.
Thank you tess for principal investment in investigation Ya good reveal work tick Sam love universe with earth rock earth is earth day today's celebrating earth birthday today ya
Yaaaay! Another useless camera sent outter space to take picrures that we never really get to see in its original form...of planets we will NEVER get to go to!
Fake animations.
Willie van het Kerkhof = fake people !!
After years and billions this is what NASA came up with, while spacex is making a rocket to go to mars
SpaceX is launching this thing and using the money to fund their Mars rocket... and the whole program only costs about $290M including the $87M payment to SpaceX. It's very cheap for a space telescope and science mission.
RollexCars NASA already reached Mars 7 years ago now it will again on may 5 and they aren't billions more like millions and they will work together for mars mission so let's not get to ignorant please.
nope, it cost 200 million and 80+ million of that is the launch cost .
Rollex clearly has no idea what the potential of this is. this mission combined with Webb will be able to detect signs of alien life in the atmospheres of planets, so for 200 million spread over 15 years we could answer the oldest and most important question humanity has ever asked itself 'are we alone?'
while the U.S spends 2 billion a fortnight on the military .......
RollexCars and what will you do on mars if it's so important? Going to Mars will be waste of time and money we know it's not habitable yet so what's the point of going there?
Dean, the point is because it's there. and not to mention all the as yet unimaginable technology such endeavors produce and the benefits to the world economies.
