Launch Escape System
A split-second decision by an escape system has saved astronauts from fiery rocket failures
21 hours ago
0
What is the primary trade-off when using a solid-fueled rocket tower for a launch escape system?
It allows continuous use throughout the entire mission without any need for jettisoning.
It is only effective at very high altitudes and speeds, limiting its use during launch.
It provides powerful thrust but adds weight and must be jettisoned during flight.

Jet Engine
Jet engines turn air into thrust with a fiery dance of compression and combustion
24 hours ago
0
What is the primary mechanism by which a jet engine generates thrust?
By using propellers to push air backward and move the aircraft forward.
By burning fuel to create explosions that directly push the aircraft forward without involving air intake.
By expelling a high-speed jet of heated gases backward, creating forward thrust through reaction.

Space Shuttle External Tank
The Space Shuttle's largest fuel tank was discarded and destroyed every mission, unlike its reusable boosters
36 hours ago
0
Why was the Space Shuttle external tank designed to be expendable rather than reusable?
Because the tank was made from materials that could not survive re-entry heating
Because recovering and refurbishing such a large, fragile tank was impractical and costly compared to its benefits
Because NASA intended to recover the tank but never developed the technology

Payload Capacity
Payload capacity shapes the fate of every flight, balancing ambition against physics.
3 days ago
0
How does payload capacity influence the design and mission planning of aircraft and launch vehicles?
It determines the maximum weight that can be carried, affecting fuel load, range, and mission objectives.
It only affects the speed of the vehicle, not the weight or mission planning.
Payload capacity is a fixed value that does not change with flight conditions or mission type.
