Zorluk: OrtaInference and Logical Deduction

Read the following passage carefully:

Under the 2026 Sovereign Space Debris Mitigation Framework, private satellite operators launching low-Earth orbit (LEO) constellations are required to equip all satellites weighing over 50 kilograms with active de-orbiting propulsion units. The protocol specifies that upon reaching their operational lifespan, these satellites must perform a controlled re-entry within 180 days to burn up in the upper atmosphere. Furthermore, operators that achieve a verified de-orbit success rate of at least 95% across their active fleet over a consecutive three-year period are granted priority orbital slot allocations for subsequent constellation deployments. However, satellites operating exclusively below an altitude of 300 kilometers are exempt from the propulsion equipment requirement, as natural atmospheric drag at this altitude ensures passive orbital decay and re-entry within 90 days of operational decommission. The framework explicitly prohibits the launching of any unpropelled satellite exceeding 50 kilograms above the 300-kilometer threshold.

Based strictly on the passage provided, which of the following is a logically necessary inference regarding satellite operators regulated by the framework?

  1. A satellite weighing 60 kilograms deployed to an operational altitude of 450 kilometers must be fitted with an active de-orbiting propulsion unit.Cevap
  2. B
    Any operator deploying satellites exclusively below 300 kilometers will automatically receive priority orbital slot allocations after three years.
  3. C
    Satellites weighing under 50 kilograms operating at an altitude of 400 kilometers are strictly prohibited from performing controlled atmospheric re-entry.
  4. D
    The total volume of space debris in low-Earth orbit will decrease by at least 95% within three years of implementing the policy.

Cevap

A satellite weighing 60 kilograms deployed to an operational altitude of 450 kilometers must be fitted with an active de-orbiting propulsion unit.
The passage explicitly dictates that all satellites weighing over 50 kilograms operating above 300 kilometers must be equipped with active de-orbiting propulsion units, and prohibits unpropelled satellites exceeding 50 kilograms above that altitude. Therefore, a 60 kilogram satellite placed at 450 kilometers altitude must necessarily be equipped with an active propulsion unit.

Adım Adım Çözüm

1
Analyze the conditions stated in the passage for mandatory propulsion units.
Satellites weighing over 50 kg deployed above 300 km altitude require active propulsion, as launching unpropelled satellites over 50 kg above 300 km is explicitly prohibited.
Establishing the precise criteria governing propulsion requirements based on weight and altitude.
2
Evaluate the test scenario: A 60 kg satellite at 450 km altitude.
The weight (60 kg) exceeds the 50 kg threshold, and the altitude (450 km) is above the 300 km exemption threshold.
Determining whether the parameters trigger the mandatory active propulsion unit requirement.
3
Conclude the logically necessary statement.
The satellite must carry an active de-orbiting propulsion unit to comply with the policy.
Validating the logical deduction strictly against the explicit facts.
