Summary
TESS (Transiting Exoplanet Survey Satellite) launched on a SpaceX Falcon 9 Block 4 from Space Launch Complex 40, Cape Canaveral SFS, FL, USA on April 18, 2018. It was SpaceX's 60th launch, 8th this year and humanity's 5,744th orbital launch attempt. It was the 9th Falcon 9 Block 4 flight and the 5th this year. Booster B1045 flew for the 1st time and landed at Of Course I Still Love You. The payload was bound for High Earth Orbit (HEO). The tracked orbit of TESS, one of 2 catalogued objects, from April 25, 2018, was 2,241 × 272,687 km inclined 28.3°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
The Transiting Exoplanet Survey Satellite (TESS) is a NASA space telescope, designed to search for exoplanets using the transit method. TESS will identify planets ranging from Earth-sized to gas giants, orbiting a wide range of stellar types and orbital distances. The principal goal of the TESS mission is to detect small planets with bright host stars in the solar neighborhood, so that detailed characterizations of the planets and their atmospheres can be performed.
News
NASA’s TESS Mission Finds Planetary System in New WayFor the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to ripples in space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound world is a super-Jupiter orbiting far from its host star. “When TESS launched, no one expected it to ever be capable […]
NASA’s TESS Mission Reveals the “Puffiest” Planets Ever FoundNASA has revealed two new “super-puff” planets, giant worlds so light that their density is comparable to cotton candy. Scientists calculate that these Jupiter-sized planets are the “puffiest” worlds ever found.
