No susceptible to memory effect like Nickel Cadmium batteries, but these batteries are highly volatile and may explode.
What is Lithium Ion?
100
Radar can detect this about an object (Optical and IR cannot).
What is density?
100
This type of system cannot adjust to compensate for changes in input.
What is open-loop system?
100
Multiple rocket stages fire simultaneously. Provides additional thrust at lift off.
What is parallel staging?
100
Russian GEO workhorse rocket.
What is Proton?
200
This configuration of batteries holds a charge longer than the other type of configuration.
What is parallel?
200
The two types of passive high resolution imagery.
What is electro-optical and IR?
200
Feet/hands of control system. Changes/decreases attitude error.
What are actuators?
200
This type of fuel is used in ICBMS and as spacelift boosters.
What is solid fuel?
200
China's first launch site. MEO and LEO; manned missions.
What is Juiquan?
300
Future of space material, materials designed from several different substances (two or more non-metals).
What are composites?
300
Smallest distance between two objects at which they appear separate and distinct.
What is spatial resolution?
300
Places information onto a signal for transmission, and reverses the process for incoming signals (stripping them apart).
What is transponder?
300
A country that must purchase space launch facilities and satellite &/or booster construction but has ground stations and receives and uses data is this space-faring tier.
What is Tier 3?
300
This rocket propulsion type has high specific impulse and can be restarted; however, the two propellants are complex to manage & can cause thermal issues.
What is Bipropellant Liquid Chemical?
400
Due to the vacuum of space, this process occurs. It can cause certain key material properties to degrade, and the emissions can condense on critical surfaces such as lenses, mirrors, and sensors.
What is outgassing?
400
Single Event Latch-Up is similar to Single Event Upset, but it impacts these rather than bits.
What are transistors?
400
This exhaust plume type means the exhaust pressure > atmospheric pressure, and the gases are not fully expanded.
What is under expansion?
400
This PNT = 1.023 Mbps.
What is Coarse Acquisition?
500
The six subsystems of a spacecraft bus.
What is structure, electrical power, propulsion, attitude control, thermal control, and TT&C?
500
Ground optical sensors can tack objects as dim as this visual magnitude star.
What is 19th? (can see 16th visual magnitude star)
500
Non-volatile memory.
What is Read Only Memory?
500
Thrust produced by 1 unit of propellant per second.
What is Specific Impulse?
500
Transfer of heat through a medium without internal relative motion of the medium along the conduction path.
