What is implied by the phrase 'Jupiter acts like a giant particle accelerator'?
What is implied by the phrase 'Jupiter acts like a giant particle accelerator'?
The radiation exposure during a flyby of Europa is described as the equivalent of a few million chest X-rays. Assuming that the average chest X-ray delivers a radiation dose of 0.1 mSv, estimate the total radiation dose (in Sieverts, Sv) received by the exterior of the spacecraft during a single flyby. Use scientific notation.

Study Notes
- Europa Clipper is NASA's first mission dedicated to studying Jupiter's icy moon Europa.
- Europa is considered one of the most promising places in the solar system to find an environment suitable for life outside Earth.
- Evidence suggests that beneath Europa's frozen surface is a global ocean of water.
- Scientists aim to determine if Europa possesses the right chemistry and energy to sustain life.
- Europa Clipper contains nine instruments plus a gravity experiment.
- It will orbit Jupiter and perform 49 flybys of Europa.
- Data collected will help scientists understand Europa's geology, composition, and interior.
- Europa Clipper will address key questions about Europa's potential habitability.
- The mission is scheduled to launch in October 2024 from NASA's Kennedy Space Center in Florida.
- It is expected to arrive at Jupiter in 2030.
- Europa's most exciting feature is the abundance of water, potentially twice the amount on Earth.
- Exploring Europa is crucial to understanding whether it's a habitable environment that could potentially support life.
- Getting close to Europa is challenging due to the intense radiation environment around Jupiter.
- Europa is about the size of Earth's moon.
- Scientists believe Europa has the three key ingredients to support life: water, energy, and essential chemical building blocks.
- This mission marks the first time a spacecraft is completely dedicated to studying Europa.
- The mission aims to explore Europa's ice and ocean.
- It will study the intersection between the ice and ocean, the chemical composition of the moon, as well as the geology and whether it's active currently.
- The spacecraft will measure light reflected off Europa using remote-sensing instruments like a camera or spectrometer.
- Other instruments will measure the environment around Europa, such as gasses or dust.
- Europa Clipper is the largest spacecraft NASA has ever built for a planetary mission.
- It weighs 13,000 pounds (six and a half tons), about the size of a huge African elephant.
- The solar arrays are massive, extending from the toes to the crown of the Statue of Liberty.
- The solar arrays are technological marvels that must withstand constant radiation exposure.
- Jupiter's radiation environment is intense, with Europa situated in the worst part.
- Jupiter acts like a giant particle accelerator.
- Charged particles trapped in Jupiter's magnetosphere rotate with it and bombard Europa.
- The spacecraft is protected in two ways: minimizing time spent in the radiation environment by orbiting Jupiter and flying by Europa, and housing sensitive electronics in an electronics vault made of about a third of an inch of aluminum.
- With each flyby of Europa, the outside of the spacecraft experiences the equivalent of a few million chest X-rays.
- The trip from Earth to Jupiter will take about 5 ½ years.
- The journey includes a flyby of Mars and another flyby of Earth for gravity assists to slingshot the spacecraft to Jupiter.
- The mission aims to unlock the secrets of Europa.
