Question 1
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:
- Remain stationary at one fixed point in the sky
- Trace a small figure-8 pattern over the course of a day
- Rise in the west and set in the east
- Orbit in a perfectly circular path overhead
Show answer & explanation
Correct answer: B - Trace a small figure-8 pattern over the course of a day
Question 2
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?
- High-resolution panchromatic optical imaging
- Multispectral visible-light imaging
- Synthetic Aperture Radar (SAR)
- Hyperspectral imaging
Show answer & explanation
Correct answer: C - Synthetic Aperture Radar (SAR)
Question 3
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?
- About 8 minutes
- 1 to 4 days
- Roughly 30 seconds
- 2 to 3 weeks
Show answer & explanation
Correct answer: B - 1 to 4 days
Question 4
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:
- Spin faster in the same direction as the desired body rotation
- Spin faster in the OPPOSITE direction of the desired body rotation
- Stop spinning entirely to release stored momentum
- Be ejected from the spacecraft to provide reaction thrust
Show answer & explanation
Correct answer: B - Spin faster in the OPPOSITE direction of the desired body rotation
Question 5
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:
- Reduced atmospheric drag at low altitudes
- A larger boost from Earth's rotational velocity (~465 m/s at the equator), which reduces the propellant required to reach geostationary orbit
- A shorter line-of-sight distance to GEO satellites
- Lower radiation exposure for ground crews and launch personnel
Show answer & explanation
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
Question 6
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?
- The individual employees who conducted the activity
- The private company itself, independently of any government
- The state (national government) under whose jurisdiction the company operates
- The United Nations Office for Outer Space Affairs
Show answer & explanation
Correct answer: C - The state (national government) under whose jurisdiction the company operates
Question 7
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?
- 1 year
- 5 years
- 25 years (the legacy international guideline)
- 100 years
Show answer & explanation
Correct answer: B - 5 years
Question 8
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:
- 5.4 km/s (about 70% of orbital velocity)
- 7.7 km/s (equal to orbital velocity)
- 10.9 km/s (about √2 times orbital velocity)
- 15.4 km/s (about twice orbital velocity)
Show answer & explanation
Correct answer: C - 10.9 km/s (about √2 times orbital velocity)
Question 9
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?
- It deflects incoming particles using an induced magnetic field
- It absorbs the kinetic energy through plastic deformation of the sheet
- It fragments and partially vaporizes the incoming particle, spreading the resulting debris cloud's energy over a larger area of the main wall
- It reflects the particle back into space using a polished mirror surface
Show answer & explanation
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
Question 10
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?
- TRL 5 - component validation in a relevant environment
- TRL 6 - system prototype demonstration in a relevant environment
- TRL 7 - system prototype demonstration in a space environment
- TRL 9 - actual system flight-proven through successful mission operations
Show answer & explanation
Correct answer: D - TRL 9 - actual system flight-proven through successful mission operations
