Ep 11. The Dangers to Earth from Outer Space

Xploration Outer Space season 2 episode 11, titled "The Dangers to Earth from Outer Space," explores the potential threats that exist in space that could endanger our planet. Host Emily Calandrelli takes viewers on a journey through space, highlighting the dangers that could potentially harm Earth.

The episode begins with an examination of asteroids, which are rocky objects floating in space that could collide with Earth. Emily explains that while most asteroids won't cause significant damage to our planet, larger ones could create a global catastrophe. To mitigate this danger, scientists are working on solutions to deflect or destroy incoming asteroids before they reach Earth.

Next, Emily discusses the potential threat of comets, which are icy objects that also orbit space. While comets are not as common as asteroids, they could still pose a danger to Earth if they collide with our planet. Emily explains that the best way to prevent a comet collision is by detecting them early and deflecting their trajectory away from Earth.

The episode also covers the hazards posed by cosmic radiation and solar flares. Cosmic radiation is a type of high-energy radiation that comes from outside our solar system and can penetrate deep into spacecraft. Solar flares, on the other hand, are bursts of energy that come from the sun and can also damage spacecraft and endanger astronauts in space. To protect against these dangers, scientists are developing new technologies to shield spacecraft and astronauts from the harmful effects of radiation.

The episode wraps up with a discussion of the potential for life in space and the impact humans could have on other planets. Emily explains that our exploration of space could have unintended consequences, such as contaminating other planets with Earth-based organisms. To prevent this from happening, scientists are taking great care to ensure that any spacecraft sent to other planets are thoroughly sanitized.

Throughout the episode, Emily emphasizes the importance of continued exploration of space, despite the potential dangers. She highlights the many benefits that come from our exploration, such as learning more about the universe and discovering new technologies that could improve life on Earth. Overall, "The Dangers to Earth from Outer Space" is an informative and engaging episode that explores the exciting and sometimes perilous world of space exploration.
