In the present day within the historical past of astronomy, Kepler completes its main mission, however continues observing.

- The Kepler Area Telescope, launched in 2009, efficiently employed the transit technique to seek for exoplanets, finally observing over 500,000 stars and contributing to the invention of just about 2,700 exoplanets.
- Following the completion of its main mission in 2012, Kepler’s supposed prolonged mission confronted important challenges as a result of failure of two gyroscopes in 2012 and 2013, which severely restricted the spacecraft’s pointing management.
- Engineers devised an modern workaround by using the momentum of the Solar’s gentle strain to keep up the spacecraft’s steady orientation, resulting in the formal approval of the K2 prolonged mission in 2014.
- Kepler continued its operations for an extra 4 years underneath the K2 methodology earlier than its retirement in October 2018, precipitated by gas exhaustion, with the Transiting Exoplanet Survey Satellite tv for pc (TESS) subsequently inheriting its exoplanet-hunting mandate.
The Kepler Space Telescope, launched March 6, 2009, was designed to go looking the Milky Manner for exoplanets. Utilizing the transit technique, Kepler finally noticed over 500,00 stars and contributed to the invention of just about 2,700 exoplanets.
Although Kepler was initially supposed for a 3.5-year mission, NASA introduced on Nov. 14, 2012, that the house telescope had efficiently accomplished its main mission and could be embarking on an prolonged mission. When a second gyroscope (additionally known as a response wheel) failed in Might 2013 – the primary having failed in July 2012 – that mission was in query, nonetheless, because it left the spacecraft with restricted management for pointing. However engineers had been capable of craft a workaround utilizing the momentum of the Solar’s gentle strain to maintain Kepler evenly and steadily directed, and the prolonged mission utilizing this system, dubbed K2, was formally accepted in Might 2014. Kepler continued to operate for an additional 4 years, and was retired in October 2018 when it ran out of gas. TESS (the Transiting Exoplanet Survey Satellite tv for pc) has since inherited its planet-hunting mantle.
