Evaluate the following statements and select the option that is accurate: Statement 1: Sun-synchronous orbits allow satellites to maintain consistent local solar time over a specific region. Statement 2: This orbital feature is ideal for continuous solar-powered communication satellites in geostationary orbit.
Only Statement 1 is correct
Statement 1 (Correct): A Sun-synchronous orbit (SSO) is a near-polar low-Earth orbit aligned such that the satellite passes over a given point on Earth at approximately the same local solar time on each pass. This makes it ideal for Earth-observation and remote-sensing missions where consistent illumination is required.
Statement 2 (Incorrect): Sun-synchronous orbits are low-Earth orbits (typically 600–800 km), not geostationary. Geostationary orbit is a separate, much higher (~35,786 km) equatorial orbit used for communication satellites; these two orbits are mutually exclusive.
Hence, only Statement 1 is correct.
