NASA’s Transiting Exoplanet Survey Satellite (TESS) has found three confirmed exoplanets, or worlds beyond our solar system, in its first three months of observations.
The mission’s sensitive cameras also captured 100 short-lived changes — most of them likely stellar outbursts — in the same region of the sky. They include six supernova explosions whose brightening light was recorded by TESS even before the outbursts were discovered by ground-based telescopes.
HAWTHORNE, Calif. (SpaceX PR) — NASA’s Launch Services Program (LSP) has certified as a Category 3 launch vehicle. Category 3 launch vehicles are certified to support NASA’s highest cost and most complex scientific missions. The following statement is from SpaceX President and Chief Operating Officer Gwynne Shotwell:
“LSP Category 3 certification is a major achievement for the Falcon 9 team and represents another key milestone in our close partnership with NASA. We are honored to have the opportunity to provide cost-effective and reliable launch services to the country’s most critical scientific payloads.’
The process of designating launch vehicles as Category 3 is designed to assure the highest practical probability of success. Falcon 9 has completed over 60 missions, including the NASA LSP missions Jason-3 and TESS.
GREENBELT, Md. (NASA PR) — NASA’s continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional. On Sept. 17, 2018, TESS — the Transiting Exoplanet Survey Satellite — shared its first science observations. Later in the week, the latest two missions to join NASA’s heliophysics fleet returned first light data: Parker Solar Probe, humanity’s first mission to “touch” the Sun, and GOLD, a mission that studies the dynamic boundary between Earth and space.

NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), is now providing valuable data to help scientists discover and study exciting new exoplanets, or planets beyond our solar system. Part of the data from TESS’ initial science orbit includes a detailed picture of the southern sky taken with all four of the spacecraft’s wide-field cameras. This “first light” science image captures a wealth of stars and other objects, including systems previously known to have exoplanets.
GREENBELT, Md. (NASA PR) — NASA’s Transiting Exoplanet Survey Satellite has started its search for planets around nearby stars, officially beginning science operations on July 25, 2018. TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth. The TESS Science Team will begin searching the data for new planets immediately after the first series arrives.
“I’m thrilled that our new planet hunter mission is ready to start scouring our solar system’s neighborhood for new worlds,” said Paul Hertz, NASA Astrophysics division director at Headquarters, Washington. “Now that we know there are more planets than stars in our universe, I look forward to the strange, fantastic worlds we’re bound to discover.”
TESS is NASA’s latest satellite to search for planets outside our solar system, known as exoplanets. The mission will spend the next two years monitoring the nearest and brightest stars for periodic dips in their light. These events, called transits, suggest that a planet may be passing in front of its star. TESS is expected to find thousands of planets using this method, some of which could potentially support life.
TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission.
Additional partners include Northrop Grumman, based in Falls Church, Virginia; NASA’s Ames Research Center in California’s Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; MIT’s Lincoln Laboratory in Lexington, Massachusetts; and the Space Telescope Science Institute in Baltimore. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.
GREENBELT, Md. (NASA PR) — In April 2018, NASA launched the Transiting Exoplanet Survey Satellite (TESS). Its main goal is to locate Earth-sized planets and larger “super-Earths” orbiting nearby stars for further study. One of the most powerful tools that will examine the atmospheres of some planets that TESS discovers will be NASA’s James Webb Space Telescope. Since observing small exoplanets with thin atmospheres like Earth will be challenging for Webb, astronomers will target easier, gas giant exoplanets first.
GREENBELT, Md. (NASA PR) — After a successful launch on April 18, 2018, NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite, is currently undergoing a series of commissioning tests before it begins searching for planets. The TESS team has reported that the spacecraft and cameras are in good health, and the spacecraft has successfully reached its final science orbit. The team continues to conduct tests in order to optimize spacecraft performance with a goal of beginning science at the end of July.
Every new mission goes through a commissioning period of testing and adjustments before beginning science operations. This serves to test how the spacecraft and its instruments are performing and determines whether any changes need to be made before the mission starts observations.

The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
GREEBELT, Md. (NASA PR) — NASA’s next planet hunter, the Transiting Exoplanet Survey Satellite (TESS), is one step closer to searching for new worlds after successfully completing a lunar flyby on May 17. The spacecraft passed about 5,000 miles from the Moon, which provided a gravity assist that helped TESS sail toward its final working orbit.
A SpaceX Falcon 9 rocket successfully launched NASA’s Transiting Exoplanet Survey Satellite (TESS) on Wednesday evening. The spacecraft successfully separated from the booster’s second stage about 50 minutes after it was launched from the Cape Canaveral Air Force Station in Florida.
TESS will use four cameras to search 85 percent of the sky for exoplanets orbiting other stars. The mission is a follow-on to the Kepler Space Telescope, which is completing a 9-year mission to survey the other 15 percent of the sky.
The on time launch occurred at 6:51 p.m. EDT. NASA reports the spacecraft’s solar arrays deployed on schedule, providing the satellite with power.
Falcon 9’s first stage successfully landed on a drone ship in the Atlantic Ocean.
SpaceX has scrubbed the launch of NASA’s TESS exo-planet hunting satellite, which had been planned for Monday evening.
“Standing down today to conduct additional GNC analysis, and teams are now working towards a targeted launch of @NASA_TESS on Wednesday, April 18,” the company tweeted.
Meanwhile, Vice President Mike Pence addressed the 34th Space Symposium in Colorado Springs earlier today. He made the following announcements:
Ret. Adm. Jim Ellis has been named to lead the National Space Council’s Users Advisory Group; and,
The space council has come up with a set of guidelines on space traffic management that will be signed by President Donald Trump and implemented by the Commerce Department. A key goal of the new guidelines is to deal with the threat of orbital debris.
