Why do capsules need heat shields?

Air friction heats them to thousands of degrees on reentry

Why are many crew capsules shaped like cones with blunt bottoms?

A blunt shape slows them and spreads heat

What does a life support system provide?

Air, water and temperature control

Why is radiation a challenge for deep-space crews?

There is no thick atmosphere or magnetic field shielding

Why do engineers try to reduce spacecraft mass?

Every kilogram needs more fuel to launch

Why do spacecraft have backup systems?

Repairs are hard far from Earth

Explanations: answer key for all 10 questions

Q1: Why do capsules need heat shields?
Answer: Air friction heats them to thousands of degrees on reentry
Ablative shields burn away slowly.
Q2: Why are many crew capsules shaped like cones with blunt bottoms?
Answer: A blunt shape slows them and spreads heat
This idea came from engineer H. Julian Allen.
Q3: What does a life support system provide?
Answer: Air, water and temperature control
It also removes carbon dioxide.
Q4: What powers most spacecraft near Earth?
Answer: Solar panels
Batteries store power for dark periods.
Q5: What protected the Space Shuttle from heat?
Answer: Thermal tiles
About 24,000 tiles covered it.
Q6: What allows spacecraft to connect in orbit?
Answer: Docking ports
Standard adapters link different vehicles.
Q7: Which company first landed an orbital-class booster in 2015?
Answer: SpaceX
Falcon 9 boosters now fly many times.
Q8: Why is radiation a challenge for deep-space crews?
Answer: There is no thick atmosphere or magnetic field shielding
Shielding adds weight.
Q9: Why do engineers try to reduce spacecraft mass?
Answer: Every kilogram needs more fuel to launch
Launch costs depend on mass.
Q10: Why do spacecraft have backup systems?
Answer: Repairs are hard far from Earth
Critical systems often have two or three copies.

Spacecraft Design Quiz – Engineering for Space

Designing spacecraft means building machines that survive launch vibration, vacuum, extreme temperatures and radiation. Every system must be reliable, light and often backed up, since repairs far from Earth are difficult or impossible.

Crewed spacecraft need life support for air, water and temperature, plus heat shields to survive reentry at around 28,000 km/h. Blunt capsule shapes, ablative shields and the Shuttle's tiles all protect against the intense heat.

Modern designs focus on reusability, with rocket boosters landing for reuse and capsules flying multiple times. Engineers also prepare for long missions to the Moon and Mars, which need better radiation protection and recycling systems.
