Nasa spacecraft blasts off to hunt alien life on a distant moon | BBC News

Summary

The NASA Europa Clipper mission, set to launch soon, aims to explore Jupiter's moon Europa, believed to harbor a vast ocean beneath its icy surface. Scientists are excited about the potential for life, as Europa contains more water than Earth. The spacecraft, designed to withstand harsh radiation, will take a five-year journey to orbit Jupiter, conducting close flybys to study the moon's conditions. The mission represents a shift in focus from Mars to the outer solar system, highlighting the importance of water worlds in the search for extraterrestrial life.

Takeaways

• 🚀 The NASA Europa Clipper mission launched from Cape Canaveral, aiming to explore Europa, a moon of Jupiter that may harbor life beneath its icy surface.
• 🌊 Europa is believed to contain a vast ocean with double the amount of water found on Earth, making it a prime candidate for supporting life.
• ⏳ The spacecraft will take five years to reach Europa, traveling approximately 1.8 billion miles through space.
• 🔭 The mission will involve multiple orbits around Jupiter and close flybys of Europa to gather crucial data about its ice crust and potential habitability.
• ⚡ The Europa Clipper is powered by large solar arrays, approximately the size of a tennis court, to meet the energy demands of its instruments in harsh conditions.
• 🛰️ The spacecraft weighs nearly six tons, making it one of NASA's largest interplanetary missions.
• 🌌 The launch was conducted by SpaceX using the Falcon Heavy rocket, known for its reliability and experience in launching spacecraft.
• ❗ The mission is not designed to land on Europa or directly find life, but rather to assess the moon's potential to support life.
• 🔬 Key instruments include radar to study the subsurface ocean and to analyze magnetic fields and plumes of water vapor.
• 🕰️ While the spacecraft will be in transit for five years, scientists are excited about the potential discoveries regarding extraterrestrial life in our solar system.

Q & A

What is the primary mission of the Europa Clipper spacecraft?

The primary mission of the Europa Clipper is to explore Europa, one of Jupiter's moons, to investigate its potential to support life due to the presence of a subsurface ocean.

Why is Europa considered a promising location for finding extraterrestrial life?

Europa is considered promising because it has a vast ocean beneath its icy surface, which contains more water than Earth, and where there is water, there may be conditions suitable for life.

How long will it take the Europa Clipper to reach Jupiter?

The Europa Clipper is expected to take five years to reach Jupiter, covering a distance of approximately 1.8 billion miles.

What challenges does the Europa Clipper face during its mission?

The challenges include navigating through a harsh radiation environment, requiring robust shielding for its electronics, and generating enough power to operate its instruments far from the Sun.

What power source does the Europa Clipper use?

Unlike most spacecraft that rely on solar power, the Europa Clipper uses nuclear power, which is necessary given its distance from the Sun.

What technology will the spacecraft use to study Europa's surface?

The spacecraft will employ advanced radar technology to look beneath Europa's icy crust and assess the subsurface ocean.

What is the significance of the plumes on Europa?

The plumes are significant because they may contain materials from the subsurface ocean, and the spacecraft aims to fly through these plumes to analyze their composition.

How does the spacecraft's design accommodate the extreme conditions of its mission?

The design includes a thick aluminum alloy shield to protect sensitive electronics from radiation, and large solar arrays to ensure sufficient power generation.

What can be expected after the Europa Clipper completes its mission?

After completing its mission, which includes 49 orbits around Jupiter, the data collected will help scientists determine if Europa has the potential to support life.

What are the potential future implications of this mission for planetary science?

The mission may shift focus in planetary science from Mars to the outer solar system, as findings could suggest that water worlds like Europa are more likely to harbor life than previously considered.
