Kepler is a part of NASA’s Discovery Program, low-cost, American focused space missions. (Kepler Spacecraft) The Kepler spacecraft worked in conjunction with the Keck Observatory, located at the top of a dormant volcano in Hawaii. (Howell) Kepler can still find exoplanets, just in a smaller field of view. Kepler uses a method called the transient method, Kepler watches a star until there is a dip in the brightness, this is a tell-tell sign that a planet just passed in front of the star. This method produces a lot of false positives, so the facts must be checked by another method. (Kepler Spacecraft)This is where the Keck Observatory plays a big part. The Keck Observatory uses infrared to photograph the coordinates that the Kepler Spacecraft sent to it. (Howell) The Kepler mission was going to last seven years, from 2009 to 2016, but in 2013 three of the four reaction wheels failed. NASA has a plan to reuse the spacecraft in its new K2 Program, which will use Kepler’s camera and also uses the energy from the Sun to push the spacecraft around its own orbit. (Wall) NASA has a new spacecraft in the midst for the future, Transiting Exoplanet Survey Satellite, or TESS. TESS will use an array of cameras to find exoplanets closer to home. …show more content…
Kepler-186f is the first most Earth-like planet to be found in the habitable zone, it orbits the Red Dwarf Kepler-186. One of the biggest discoveries for “Goldilocks Planets” is the discovery of the Solar System Kepler-62. Kepler-62 is a five planet system 1200 light years from Earth. Solar System Kepler-62 has two planets that are within its habitable zone, Kepler-62e and Kepler-62f. Both planets could have water, but Kepler-62f would be frozen unless there are greenhouse gasses in the atmosphere to heat it up. Kepler-62e would fit Heller’s model for a Super-Earth. (Alien Planet Earth) There have been recent discoveries of Earth-like exoplanets, Kepler-438b and Kepler-442b. The size and location of these planets means that these planets have a high chance of being rocky, like the Earth. While Kepler-438b is closer in size to the Earth, Kepler-442b is a better choice due to its location, Kepler-442b gets around seventy percent of the solar energy that the Earth gets. “We are now closer than we’ve ever been to finding a twin for the Earth,” says NASA scientist Fergal Mullally.
