good morning all,
 I returned from Brazil Sunday, around noon, after a 22 hours of travel…it was simply amazing every way….Natal, Brazil is such beautiful city right on the beach, the weather was great, although rained quite a bit…now I have to get ready to leave for England on Sat…it is crazy…so much fun….I want to get this to you so hopefully you can share in a very special launch today, April 16th….NASA’s mission to look for new planets…you can see the launch live on  http://www.nasa.gov/nasatv <http://www.nasa.gov/nasatv>   or on https://spaceflightnow.com  it is 6:32PM EST (New York)…great timing for those of you are about 6 hours ahead of the US….… wishing you all a wonderful day…. we have to always remember to do our best, enjoy everything we do, live in the present, be appreciative of the good in our lives, make each day special, smile & have fun! Gabe

Live coverage: NASA planet-hunting satellite aboard Falcon 9 launch Monday <https://spaceflightnow.com/2018/04/16/falcon-9-tess-mission-status-center/>
April 16, 2018
SpaceX’s next Falcon 9 rocket launch is set for Monday at Cape Canaveral, carrying NASA’s Transiting Exoplanet Survey Satellite, a plant-hunting observatory that will search for worlds around bright stars in our solar neighborhood. Liftoff is set for 6:32:07 p.m. EDT (2232:07 GMT) Monday from Cape Canaveral’s Complex 40 launch pad, and SpaceX will attempt to recover the Falcon 9’s first stage on a drone ship in the Atlantic Ocean.

NASA's TESS Mission Hopes to Find Exoplanets Beyond Our Solar System 
The worlds orbiting other stars are called “exoplanets <https://www.nasa.gov/feature/jpl/what-in-the-world-is-an-exoplanet>,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. This artist’s impression shows an exoplanet orbiting the Sun-like star HD 85512 in the southern constellation of Vela (The Sail).

This rocky super-Earth is an illustration of the type of planets future telescopes, like NASA's Transiting Exoplanet Survey Satellite (TESS) <https://www.nasa.gov/content/about-tess> and James Webb, hope to find outside our solar system. TESS, slated to launch on April 16, 2018, is the next step in the search for planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets.

A Science Pipeline to New Planet Discoveries

NASA’s ongoing search for life in the universe produces a lot of data. The agency’s new planet-hunting mission, the Transiting Exoplanet Survey Satellite, or TESS, will collect 27 gigabytes per day in its all-sky search for undiscovered planets orbiting 200,000 of the brightest and closest stars in our solar neighborhood. That’s the equivalent of about 6,500 song files beaming down to Earth every two weeks. The music of the stars, however, is not as polished for human ears as the latest Taylor Swift album. To get ready for scientific discovery, the data needs a bit of fine tuning. One of the first steps in the data’s journey from deep space to a scientist’s laptop is the Science Processing Operations Center, called SPOC, at NASA's Ames Research Center in Silicon Valley, the design of which is based on the Kepler mission’s Science Operations Center, called the SOC, also at Ames. The SOC has been chugging along for more than a decade, spitting out tens of thousands of possible planet signals from the Kepler space telescope, NASA’s groundbreaking planet-finding mission that’s revolutionized our view of the heavens as a place chock-full of other worlds where life could exist. Among Kepler’s many gifts to TESS is its science data pipeline, which will provide the public’s “data of record” for the mission. About 75 percent of the Kepler pipeline, which took over 150 person-years to develop, remains the same for TESS, giving this new mission a leg up on discoveries. A data pipeline is like an assembly line where computer algorithms act in stages to refine data and extract types of information — in this case, the possible signals of planets. TESS’s cameras observe the slight dip in the brightness of a star as a planet crosses, or transits, in front of the star. Over time, a pattern emerges as the dips line up across multiple transits, revealing the signal of an orbiting planet. It’s a simple concept with a history of successful science, but the raw data, appearing as two-minute digital counts of brightness on each pixel, is contaminated with signals from the telescope and the sky when it first arrives here on Earth. SPOC’s science data pipeline does a cleanup job, and paves the way for the mission’s science office branch at the Massachusetts Institute of Technology to pick out the most promising planet candidates. From there, the Harvard-Smithsonian Center for Astrophysics at Harvard University coordinates follow-up observations to determine which candidates are bona fide planets. NASA Ames’ Pleiades supercomputer, one of the most powerful systems in the world, has the power to process TESS’s biweekly data deluge of almost 10 billion pixels in three to five days, a cadence that enables SPOC to keep up with the volume of incoming data. TESS’s mission is to identify the most promising exoplanets for follow-up observations. Future missions and observatories, such as the James Webb Space Telescope, will apply new technologies to study these exoplanets’ atmospheres in search of the chemical signatures of life. TESS’s first public release of pipeline-processed data is planned for the beginning of 2019. Astronomers will then begin to peer at data from entirely new areas of the sky where we await new discoveries from these singing stars and their quietly humming planets.

The Transiting Exoplanet Survey Satellite (TESS) is a NASA Astrophysics Explorer <https://science.nasa.gov/astrophysics/programs/astrophysics-explorers> mission led by MIT, and managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland.  The mission’s science data pipeline has been developed by the Science Processing Operations Center (SPOC) at NASA’s Ames Research Center in Silicon Valley. The pixel and light curve products, and the transiting planet search products, as well as the calibrated full frame images will be archived to the Mikulski Archive for Space Telescopes (MAST). Additional partners include Orbital ATK, the Harvard-Smithsonian Center for Astrophysics, and the Space Telescope Science Institute. More than a dozen universities, research institutes and observatories worldwide are participants <https://tess.gsfc.nasa.gov/meettheteam.html> in the mission.

What in the World is an ‘Exoplanet?’
The Milky Way, our own galaxy, stretches across the sky above the La Silla telescope in Chile. Hidden inside our own galaxy are trillions of planets, most waiting to be found.

Step outside on a clear night, and you can be sure of something our ancestors could only imagine: Every star you see likely plays host to at least one planet. The worlds orbiting other stars are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze. They can orbit their stars so tightly that a “year” lasts only a few days; they can orbit two suns at once. Some exoplanets are sunless rogues, wandering through the galaxy in permanent darkness. That galaxy, the Milky Way, is the thick stream of stars that cuts across the sky on the darkest, clearest nights. Its spiraling expanse probably contains about 400 billion stars, our Sun among them. And if each of those stars has not just one planet, but, like ours, a whole system of them, then the number of planets in the galaxy is truly astronomical: We’re already heading into the trillions.
