In the space industry context, "Clipper" refers to NASA's Europa Clipper mission, an interplanetary spacecraft designed to conduct detailed reconnaissance of Jupiter's moon Europa and investigate whether it has conditions suitable for life. Specifically, the mission aims to explore Europa's ice-covered surface, characterize its ocean and ice shell, and study its atmosphere, composition, and geology. Europa is of particular interest to scientists because it is believed to have a subsurface ocean beneath its icy crust, which could potentially harbor extraterrestrial life.

Mission Objectives

The Europa Clipper mission has several key scientific objectives:

  • Ice Shell and Ocean: Determine the thickness of Europa's ice shell, and the depth and salinity of its ocean.
  • Composition: Study the composition of Europa's surface and subsurface to understand the moon's habitability.
  • Geology: Investigate the geology of Europa's surface, including any current or past geologic activity.
  • Atmosphere: Characterize the thin atmosphere of Europa and its interactions with Jupiter's magnetosphere.

Instruments and Technologies

The Europa Clipper spacecraft will carry a suite of sophisticated scientific instruments designed to meet its mission objectives, including ice-penetrating radar, high-resolution cameras, spectrometers, and a magnetometer. These instruments will collect data during multiple flybys of Europa while the spacecraft orbits Jupiter, allowing for comprehensive coverage and analysis of Europa's surface and environment.

Challenges and Innovations

  • Radiation: One of the significant challenges of the Europa Clipper mission is the intense radiation environment around Jupiter, which can damage spacecraft systems. The spacecraft's design includes radiation shielding to protect its instruments and electronics.
  • Remote Operations: Operating a spacecraft in the outer solar system requires advanced autonomous systems and long-duration power sources, as solar energy is less effective at Jupiter's distance from the Sun. The mission will rely on radioisotope thermoelectric generators (RTGs) for power.

Launch and Timeline

As of my last update, the Europa Clipper mission was targeted for launch in the 2020s, with a multi-year journey to Jupiter following its launch. Upon arrival, the spacecraft will conduct dozens of flybys of Europa, providing a detailed survey of the moon's ice shell, surface, and potential subsurface ocean.


The Europa Clipper mission represents a significant step forward in our exploration of the outer solar system and the search for habitable environments beyond Earth. By studying Europa in detail, scientists hope to gain insights into the moon's potential for life and the processes that shape icy worlds in our solar system and beyond.
