Space Junk

What is Space Junk?

Space junk is debris in Earth's orbit that can pose a threat to satellites and spacecraft.

How does Space Junk affect Space?

Space junk can damage satellites and spacecraft
It can pose a threat to astronauts

Carbon Emissions - Space

How Carbon Emissions affect Space:

Carbon Emissions can affect the atmosphere
It can lead to climate change
It can affect the health of astronauts
It can affect the health of people on Earth
It can damage satellites or disrupt them

Rockets can increase carbon emissions, and potentially increase Global Warming!

Mars

The Red Planet

Mars is the fourth planet from the Sun and is known for its reddish appearance, which is caused by iron oxide (rust) on its surface. It has polar ice caps, the largest volcano in the solar system, and possible signs of ancient water flows.

Europa

Jupiter’s Icy Moon

Europa, one of Jupiter’s largest moons, has a smooth icy surface. Beneath the ice, scientists believe a global ocean exists, making Europa a strong candidate for extraterrestrial microbial life.

Enceladus

Saturn’s Ocean World

Enceladus, a small moon of Saturn, ejects plumes of water vapor and ice from its surface. These geysers suggest a subsurface ocean that may harbor the conditions for life.

Kepler-186f

Earth-Sized Exoplanet

Kepler-186f orbits within its star’s habitable zone and is close in size to Earth. It receives less sunlight than Earth, but liquid water could still exist under the right conditions.

Gliese 581g

Super-Earth Candidate

Located about 20 light years away, Gliese 581g is thought to lie in the habitable zone of its star. While its existence is debated, if confirmed it could have conditions suitable for life.

HD 40307g

Potentially Habitable Super-Earth

HD 40307g is a super-Earth orbiting in the habitable zone of its parent star. Its size suggests a rocky composition, and it may have a stable atmosphere that supports habitability.

Proxima Centauri b

Our Nearest Exoplanet

Orbiting the closest star to the Sun, Proxima Centauri b lies in its star’s habitable zone. Despite strong stellar flares, it remains one of the best nearby candidates for life.

TRAPPIST-1e

Part of the TRAPPIST-1 System

TRAPPIST-1e is one of seven Earth-sized planets orbiting a red dwarf star. It sits in the habitable zone and has conditions that could allow for liquid water.

Kepler-22b

Super-Earth in Habitable Zone

Kepler-22b is about 2.4 times the size of Earth and orbits within its star’s habitable zone. Scientists speculate it could have a water-rich environment.

Gliese 667Cc

Well-Positioned for Life

Gliese 667Cc orbits in the habitable zone of a triple star system. Its location and potential surface temperatures make it a strong candidate for supporting life.
