Mission Overview The Kepler Mission was a space observatory designed to survey a specific portion of our region of the Milky Way galaxy. Kepler lost a second spacecraft reaction wheel in May of , which effectively ended data collection in the original Kepler field after 4 years of continuous monitoring.
However, all other Kepler assets remained intact and were used for extended observations, and dubbed the K2 mission. Kepler left a legacy of more than 2, exoplanet discoveries. Relevance to Astrobiology Kepler searched for Earth-sized planets that orbit in the habitable zone of their host star. By October , and after nine years in deep space collecting data, Kepler had discovered more than 2, planets outside our solar system.
Amongst the Kepler discoveries is Keplerf, the first validated Earth-size planet in the habitable zone of a star other than the Sun. The vast amount of data collected by Kepler will continued to be analyzed by researchers in the years to come, providing further discoveries that will help to guide the future direction of astrobiology science.
NASA Astrobiology Involvement Numerous researchers supported by the Astrobiology Program are working with data from Kepler to discover potentially habitable exoplanets. Astrobiologists also use this data to develop new techniques for studying exoplanets in greater and greater detail.
This work will inform future missions to characterize exoplanets and exomoons, and possibly identify signs of life by analyzing attributes of these distant worlds, such as atmospheric composition.
Results from this research are relevant in constraining the potential habitability of Earth-sized planets discovered by the Kepler mission. Additionally, VPL Team member Eric Agol, who is also a Kepler guest observer, discovered the most potentially habitable planet to date in the Kepler data, and continues to develop planet detection algorithms to improve the science yield from the Kepler data. VPL Team member Lucianne Walkowicz Berkeley is also a member of the Kepler scientific analysis team and works on understanding the photometric variability and flare frequency and strength for stars that serve as planetary hosts.
All of the planets crowd closer to their star than Earth to our Sun. The discovery was made, in part, using artificial intelligence. The discovery was a highlight among the contributions of citizen scientists who combed through immense amounts of K2 data in search of exoplanets.
Scientists went on to find a fifth planet in the system. In May , Kepler finished six months of supernovae observations. The spacecraft captured the beginning stages of the stellar explosions with unprecedented precision to help resolve a longstanding mystery: What sets them off? On Oct. The spacecraft was retired in its current, safe orbit, away from Earth.
Kepler left behind a legacy of more than 2, planet discoveries from outside our solar system, many of which could be promising places for life. Before retiring the spacecraft, scientists pushed Kepler to its full potential, successfully completing multiple observation campaigns and downloading valuable science data even after initial warnings of low fuel.

What was Kepler? Kepler: First Light and Last Light Kepler's "first light image" of its field of stars in left compared to its final image from right. The blackened gaps in the center and along the top of the image are the result of earlier random part failures in the camera. Due to the modular design, the losses did not impact the rest of the instrument. Do you see a monster in this picture? Do the bright spots near the top of the image look like the piercing eyes and elongated snout of Godzilla?
Signs of a planet transiting a star outside of the Milky Way galaxy may have been detected for the first time. A discovery followed the release of a Hubble photo of a striking example of a deep-space phenomenon dubbed an "Einstein ring.
The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy beyond. Studying the Edge of the Sun's Magnetic Bubble. Over the next 12 years, Lucy will fly by one main-belt asteroid and seven Trojan asteroids. JPL's lucky peanuts are an unofficial tradition at big mission events. A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought.
DART's mission is to determine if flying a spacecraft into a small solar system body could be a reliable technique to deflect an asteroid. The spacecraft will continue collecting data about Mars, but engineers will stop sending commands until mid-October. Lastly, the new study assumes a simple model for these exoplanets that could depart dramatically from conditions in the real world some of these stars may form binary star systems with other stars, for example.
The whole point of Kepler was to help scientists figure out what kinds of interstellar objects they ought to devote more resources to studying to find extraterrestrial life, especially with space-based telescopes whose observation time is limited.
This paper tells us there are a lot of planets out there in the right place for life to form. This post has been updated with additional comments from Jacob Haqq Misra. A new simulation shows that when the DART mission hits the target asteroid, it could send it spinning and wobbling in a dramatic way. The Decadal Survey, expected at the end of September, sets the tone for a new era of space exploration. One team of researchers wants the survey to use AI to forecast growing science fields.
