Spacecraft Propulsion and Space Exploration Risks

These flashcards cover various topics related to spacecraft propulsion, the risks of space exploration, the International Space Station, and telescopes.

What are the different ways spacecraft have been propelled through space?

Spacecraft can be propelled through chemical propulsion, electric propulsion, and ion propulsion, each providing different thrust levels and efficiencies.

What risks are associated with space exploration?

Environmental Hazards, Psychological Challenges, and the Body's response to Microgravity.

Which risk associated with space exploration poses the greatest threat to survival?

Environmental Hazards generally pose the greatest risk, while Psychological Challenges are often considered the least risk.

What is the difference between a shuttle and a probe?

A shuttle is designed for carrying astronauts and cargo to space and back, while a probe is an unmanned spacecraft sent to explore other celestial bodies.

What is the ISS and why is it important?

The International Space Station (ISS) is a space station that serves as a microgravity and space environment research laboratory. It is important for international cooperation in space exploration.

How do astronauts manage water usage on the ISS?

Astronauts recycle water using advanced filtration and purification systems to ensure a constant access to water.

What is the Hubble Telescope and how does it work?

The Hubble Telescope is an optical telescope that uses mirrors and cameras to capture images of celestial objects, operating in the visible, ultraviolet, and near-infrared spectrum.

What materials does the Hubble Telescope use to see into space?

The Hubble Telescope utilizes a combination of glass mirrors and advanced camera technology.

What are the advantages of optical telescopes?

Optical telescopes provide high-resolution images and can observe a range of visible light wavelengths.

What are the disadvantages of optical telescopes?

Optical telescopes can be limited by atmospheric conditions and can only observe objects that emit visible light.

What are the advantages of radio telescopes?

Radio telescopes can observe astronomical objects regardless of weather and can detect signals that are not visible to optical telescopes.

What are the disadvantages of radio telescopes?

Radio telescopes generally produce lower resolution images compared to optical telescopes and require large structures.
