The spacecraft is estimated about $337 million and it is of a washing machine-sized spacecraft. He said, "Our galaxy is full of stars, about 100 billion other stars, and if each one hosts planets, and 1/5 are small like earth that means there are 20 billion possibilities for life to exist outside of our solar system and potentially develop into something intelligent".
The Transiting Exoplanet Survey Satellite (TESS), the heir to NASA's Kepler exoplanet mission throne, is set to orbit Earth while pointing it's viewfinders out to space. The Kepler space telescope has been looking for these cosmic winks for a few years and it helped identify thousands of planet candidates. The Kepler mission was a statistical exploration looking to see how frequently planets occur around stars, Harvard astronomer David Latham told Space.com.
Kepler's field of view covered one 400th of the Milky Way and confirmed the presence of 1,284 new planets, whereas TESS is an ultra-wide-angle lens that will observe almost the entire visible sky, with a camera array that has four 16.4-megapixel imaging units, each covering a square of sky 24 degrees across, making for a tall "segment" of the sky like a long Tetris block.
During this time, TESS will study and document 200,000 of the brightest stars near the sun to search for any transiting exoplanets. "We can understand how large the planet is and how far it orbits from its start to understand the context of the earth against all the other planets in the galaxy". "The TESS planets are going to be the ones you're going to look at".
"The moon and the satellite are in a sort of dance", said Joel Villasenor, an MIT researcher and instrument scientist for TESS.More news: Saudi king slams Iran's 'interference' as Arab leaders meet

While Kepler's planets could only be viewed by telescopes in the northern hemisphere, TESS will discover planets that can be seen in the southern hemisphere. Guerrero said that the TESS team is working on the ways to share those findings publicly. The research team claims that the inability to make space babies would endanger humankind in the likelihood that we have to leave our planet one day.
The satellite's cameras will look at one part of the sky and take photos of it, searching for planets transiting their stars.
The NASA team stressed in its announcement that Tess does not and can not look for atmospheric signs of life.
"Twenty years ago, if you told me that we were going to do this kind of spectroscopy of atmospheres of planets around other stars, I would have said you're insane", said Latham. However, human sperm is a lot more complex and inherently varied in motion and appearance says NASA. "They can move around and get themselves in the right spot where the star is", he said.
