An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission’s next phase
The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science payload.
„We are all excited about the decision that moves the Europa Clipper mission one key step closer to unlocking the mysteries of this ocean world,“ said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. „We are building upon the scientific insights received from the flagship Galileo and Cassini spacecraft and working to advance our understanding of our cosmic origin, and even life elsewhere.“
The mission will conduct an in-depth exploration of Jupiter’s moon Europa and investigate whether the icy moon could harbor conditions suitable for life, honing our insights into astrobiology. To develop this mission in the most cost-effective fashion, NASA is targeting to have the Europa Clipper spacecraft complete and ready for launch as early as 2023. The agency baseline commitment, however, supports a launch readiness date by 2025.
This artist’s rendering shows NASA’s Europa Clipper spacecraft, which is being developed for a launch sometime in the 2020s. This view shows the spacecraft configuration, which could change before launch, as of early 2016.
The mission would place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of the giant planet’s moon Europa — a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life. The highly capable, radiation-tolerant spacecraft would enter into a long, looping orbit around Jupiter to perform repeated close flybys of Europa.
The concept image shows two large solar arrays extending from the sides of the spacecraft, to which the mission’s ice-penetrating radar antennas are attached. A saucer-shaped high-gain antenna is also side mounted, with a magnetometer boom placed next to it. On the forward end of the spacecraft (at left in this view) is a remote-sensing palette, which houses the rest of the science instrument payload.
The nominal mission would perform at least 45 flybys of Europa at altitudes varying from 1,700 miles to 16 miles (2,700 kilometers to 25 kilometers) above the surface.
NASA’s Jet Propulsion Laboratory in Pasadena, California, leads the development of the Europa Clipper mission in partnership with the Johns Hopkins University Applied Physics Laboratory for the Science Mission Directorate. Europa Clipper is managed by the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
