NASA has decided to retire the spacecraft by shutting down its radio transmitters, leaving it to drift slowly through space, falling farther and farther behind Earth’s elliptical track around the Sun. Without adequate fuel reserves, the spacecraft cannot turn towards Earth to send home the precious pictures it takes while staring at the sky in search of planets crossing in front of stars.
Launched in 2009 on a 3.5-year mission to get a statistical sense of the number of exoplanets in the Milky Way, the telescope has operated for 9 years, thanks to austere fuel use by its mission team. But on 23 October, NASA learned that the spacecraft had fallen asleep, a side effect of the fact that it was out of fuel. The one-way light travel time between Kepler and Earth is 9.3 minutes.Īfter that, Kepler tried to get back to work.

There, Kepler turned toward Earth and transmitted the precious data it recently gathered while staring at a patch of sky in the constellation Aquarius. On 11 October, NASA’s Deep Space Network turned its gaze to a spot 170 million kilometers behind Earth in our path around the Sun.

Another method proposed is to study systems over time this could help avoid a possibility where planets with close orbits would appear in each other’s PSF. One of the methods involves developing new methods of data processing to remove the possibility of such a photobombing phenomenon skewing the results of a study. The study proposes multiple strategies to deal with this issue. “We found that such a telescope would sometimes see potential exo-Earths beyond 30 light-years distance blended with additional planets in their systems, including those that are outside of the habitable zone, for a range of different wavelengths of interest,” said Saxena. They modelled a situation where an astronomer from another 30 light years away could be looking at the Earth with a telescope similar to the one recommended by the 2020 Astrophysics Decadal Survey. Scientists examined a similar scenario, except reversed. This would complicate or even prevent the detection and confirmation of an exo-Earth, a potentially Earth-like planet outside of our solar system. When that happens, the data gathered about the exoplanet would be affected by whatever objects were photobombing it.
