Space Exploration Mission Current Affairs - 2020
NASA will send first-ever mission named as InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) dedicated to exploring the deep interior of Mars.
InSight will be stationary lander that will be launched in May 2018. It will be first NASA mission since the Apollo moon landings to place seismometer, a device that measures quakes on the soil of another planet.
InSight is NASA’s Discovery Program mission that aims to place stationary lander equipped with seismometer and heat transfer probe on surface of Mars to study red planet’s early geological evolution. It is terrestrial planet explorer that will address one of most fundamental issues of planetary and solar system science. It will help in understanding processes that shaped rocky planets of inner solar system (including Earth) more than four billion years ago. The robotic lander will perform a radio science experiment to study internal structure of Mars by deploying seismometer and a burrowing heat probe. It will measure Mar’s vital signs such as pulse (seismology), temperature (heat flow probe) and reflexes (precision tracking). It will let scientists understand how different its crust, mantle and core are from Earth.

NASA has partnered with private space launching company SpaceX to launch Transiting Exoplanet Survey Satellite (TESS) to search for exoplanets using the transit method.
TESS is designed to carry out first spaceborne all-sky transiting exoplanet survey. It is equipped with four wide-angle telescopes and associated charge-coupled device (CCD) detectors. It is planned to be launched in April 2018 on board of SpaceX’s Falcon 9 rocket from the Cape Canaveral Air Force Station.
Transiting Exoplanet Survey Satellite (TESS)
The primary mission objective of TESS is to survey brightest stars near Earth for transiting exoplanets over two-year period. It will use array of wide-field cameras to perform all-sky survey. It will create catalog of thousands of exoplanet candidates using transit photometry method.
It will provide prime targets for further characterization by James Webb Space Telescope, as well as other large ground-based and space-based telescopes of the future. With TESS, it will be possible to study mass, size, density and orbit of large cohort of small planets, including sample of rocky worlds in habitable zones (goldilocks zone) of their host stars. This will reveal whether planets are rocky (like Earth), gas or jovian giants (like Jupiter) or something even more unusual.
