A satellite has an orbital period of exactly 24 hours but an inclination of 5° and an eccentricity of 0.01. From a fixed ground location, this satellite will appear to:
Correct answer: B - Trace a small figure-8 pattern over the course of a day
An intelligence analyst needs to monitor activity at a port that is frequently obscured by heavy cloud cover and is often observed at night. Which sensor type is BEST suited for this requirement?
Correct answer: C - Synthetic Aperture Radar (SAR)
A satellite operator detects a major X-class solar flare on the Sun. Approximately how long do they have before the associated coronal mass ejection (CME) is most likely to reach Earth's magnetosphere?
Correct answer: B - 1 to 4 days
A 3-axis-stabilized satellite uses a reaction wheel to slew the spacecraft in pitch. To pitch the spacecraft body upward, the reaction wheel must:
Correct answer: B - Spin faster in the OPPOSITE direction of the desired body rotation
The European Space Agency's primary launch site is located at Kourou, French Guiana, at approximately 5° north latitude. The PRIMARY operational advantage of this near-equatorial location for missions targeting geostationary orbit is:
Correct answer: B - A larger boost from Earth's rotational velocity (~465 m/s at the equator), which reduces the propellant required to reach geostationary orbit
Under Article VI of the Outer Space Treaty (1967), if a private commercial company headquartered in a signatory nation conducts an activity in space that causes damage, who bears international responsibility for that activity?
Correct answer: C - The state (national government) under whose jurisdiction the company operates
As of its 2022 rule update, the U.S. Federal Communications Commission (FCC) requires LEO satellites licensed in the United States to deorbit within how many years after the end of their mission?
Correct answer: B - 5 years
A satellite in a circular orbit at 400 km altitude has an orbital velocity of approximately 7.7 km/s. The escape velocity from that same altitude is approximately:
Correct answer: C - 10.9 km/s (about √2 times orbital velocity)
A spacecraft designer adds a thin aluminum sheet positioned several centimeters in front of the main pressure wall. What is the PRIMARY mechanism by which this Whipple shield protects the spacecraft from hypervelocity debris?
Correct answer: C - It fragments and partially vaporizes the incoming particle, spreading the resulting debris cloud's energy over a larger area of the main wall
A new propulsion technology has been demonstrated successfully on a satellite during an actual operational on-orbit mission. What Technology Readiness Level (TRL) does this technology achieve?
Correct answer: D - TRL 9 - actual system flight-proven through successful mission operations
