Thank you to DRAPER and it's Hack the moon initiative to supporting PBS digital studios If we look at the vast size and age of the universe Its nearly impossible for their not be extraterrestrial Life out there. But it may be hundrads or Even thousand years before we have the technology to visit other stars to find aliens That's why scientists are ... Read More

Questions & Answers

Q: What are the objectives of the Mars 2020 rover mission?

The primary objective of the Mars 2020 rover is to determine whether life ever existed on Mars. It will collect samples and store them for future missions to bring back to Earth for detailed analysis, enabling new levels of scientific study.

Q: How does NASA plan to study Europa's potential for life?

NASA will launch the Europa Clipper mission in 2023, equipped with remote sensing instruments, ice penetrating radar, and gravity science experiments. These tools will analyze Europa's characteristics and search for evidence of life-supporting conditions.

Q: What provides energy to Europa's deep ocean and potentially supports life?

The tidal forces from Jupiter's gravitational field supply the energy that keeps Europa's ocean liquid. This energy, along with volcanic activity or hydrothermal vents on the sea floor, could infuse the water with the necessary energy and nutrients for life.

Q: How are scientists redefining what it means to be alive in the search for extraterrestrial life?

Scientists are open to redefining what constitutes life as they search for clues in unfamiliar environments. Life on other planets or moons may not be recognizable to us, and the goal is to find any form of life and prove that Earth is not the only abode of life in the universe.

Summary & Key Takeaways

  • Mars 2020 rover aims to determine whether life ever existed on Mars by studying the Jezero crater, which was once a warm, watery world. Scientists hope to find Martian rocks with preserved ancient organic molecules.

  • Europa, Jupiter's moon, may hold the key to life with its deep ocean of liquid water beneath a frozen surface. NASA plans to launch the Europa Clipper mission in 2023 to study this intriguing moon.

  • Life requires both water and energy. Europa's ocean may be energized by the tidal forces from Jupiter's gravitational field, potentially supporting life in hydrothermal vents on its sea floor.
