NASA’s Transiting Exoplanet Survey Satellite (TESS) begins operations

 

NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Transiting Exoplanet Survey Satellite has started its search for planets around nearby stars, officially beginning science operations on July 25th, 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.

NASA’s Transiting Exoplanet Survey Satellite (TESS) launched Wednesday

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Transiting Exoplanet Survey Satellite (TESS) launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life.

TESS, which is expected to find thousands of new exoplanets orbiting nearby stars, lifted off at 5:51pm CDT Wednesday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. At 6:53pm, the twin solar arrays that will power the spacecraft successfully deployed.

NASA’s Transiting Exoplanet Survey Satellite to look for undiscovered Planets

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Transiting Exoplanet Survey Satellite (TESS) is undergoing final preparations in Florida for its April 16th launch to find undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life.

“One of the biggest questions in exoplanet exploration is: If an astronomer finds a planet in a star’s habitable zone, will it be interesting from a biologist’s point of view?” said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology (MIT) Kavli Institute for Astrophysics and Space Research in Cambridge, which is leading the mission. “We expect TESS will discover a number of planets whose atmospheric compositions, which hold potential clues to the presence of life, could be precisely measured by future observers.”

NASA picks Six Explorers Program proposals to study our Solar System

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.

Three of these proposed missions, called FINESSE, SPHEREx and CASE, are managed by NASA’s Jet Propulsion Laboratory in Pasadena, California. FINESSE and CASE additionally have their principal investigator based at JPL.

NASA GUSTO mission to examine the Cosmic Material between Stars

 

Written by Felicia Chou
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has selected a science mission that will measure emissions from the interstellar medium, which is the cosmic material found between stars. This data will help scientists determine the life cycle of interstellar gas in our Milky Way galaxy, witness the formation and destruction of star-forming clouds, and understand the dynamics and gas flow in the vicinity of the center of our galaxy.

The Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) mission, led by principal investigator of the University of Arizona, Christopher Walker, will fly an Ultralong-Duration Balloon (ULDB) carrying a telescope with carbon, oxygen and nitrogen emission line detectors.

NASA has selected a science mission that will untangle the complexities of the interstellar medium, and map out large sections of the plane of our Milky Way galaxy and the Large Magellanic Cloud. (NASA, ESA, and Hubble Heritage Team)
