Atmosphere
Increased UV exposure, due to ozone depletion, raises the risk of this common type of cancer.
What is skin cancer?
These emissions stay in the atmosphere for decades to centuries and are the main driver of long-term warming through the greenhouse effect.
What are CO2 emissions?
This trend, driven by satellite constellations and the space industry, is increasing rocket emissions.
What is the rapid growth in launch frequency?
This way of keeping a sustainable space practice is known for having extended functional lifespans.
What is reuse/refurbishment?
This problem worsens as launch frequency increases, because more objects are left in orbit, raising the risk of collisions and chain reactions.
What is space debris accumulation?
In this atmospheric layer, there are several rocket emissions (such as soot (black carbon), nitrogen oxides, alumina particles, chlorine, hydrochloric acid and water vapors)
What is the stratosphere?
This activity doesn't have much of an impact on the climate change – yet.
What is spaceflight?
This event is an explosive spectacle, and mishaps have hurled debris into nearby wetlands and habitats.
What are rockets blasting/taking off?
This type of misleading marketing makes a company appear more environmentally friendly than it is.
What is greenwashing?
In low orbit, satellites have approximately this lifespan before being deorbited and replaced.
What is 5 years?
This ongoing healing is threatened by increasing rocket activity.
What is ozone recovery?
Launch sites cause this specific type of environmental damage to the surrounding land through propellant spills and exhaust residues.
What is soil and water contamination?
This private company’s rocket was used as an example of emissions per launch and also known for their rockets landing back on earth.
What is Space X?
This 1987 international treaty could be amended to include rocket emissions to change policy.
What is the Montreal Protocol?
This term is used to describe the hundreds of millions of fragments orbiting Earth at ten times the speed of a bullet.
What is space debris/junk?
This major pollutant from rockets is primarily responsible for ozone depletion in the study.
What is black carbon?
This is the reason why rocket pollution is considered more dangerous than the same amount from a car or an airplane.
What is because it is released directly into the upper atmosphere where it lingers much longer?
What is the general term for the explosive force that propels a rocket off the ground at launch.
What is thrust?
This funding method allows ordinary people to financially support green rocket startups without being a millionaire.
What is crowdfunding?
This is the name given to the dangerous theoretical scenario where collisions in orbit create a cascade of debris making entire global shells unusable.
What is Kessler Syndrome?
Scientists have given a nickname for this atmospheric layer, as its original name is the thermosphere.
What is the ignorosphere?
In fact, when this element is realised from rocket fuel into the atmosphere, it can act as a greenhouse gas, whereas on the surface it does not act the same way.
What is water vapour?
This is the two-stage process that happens to most rockets after launch, where the first stage separates and falls back towards Earth.
What is stage separation? (also known as booster separation/stage decoupling)
Before investing in a space company’s “green” claims, activists recommend doing this to separate PR from reality.
What is factchecking?
This is what the letters LEO stand for in space terminology regarding the space debris in orbit.
What is Low Earth Orbit?
