The first and last images captured by the NASA-JPL space telescope Kepler are shown here side-by-side.

This craft was launched back on March 7th, 2009, and its planned mission duration was 3.5 years.

A full 9 years, 7 months, and 23 days later, it was still doing work.

This craft was named after astronomer Johannes Kepler, and was launched specifically to find Earth-sized planets orbiting stars other than our own.

Kepler was made to be a space observatory, and it’s been floating in space on an Earth-trailing heliocentric orbit since it was put in space.

The first announcement of the retirement of this mission was made back on October 30th, 2018.
