Why must most infrared telescopes operate at very high altitudes or in space?
When astronomers discuss the apertures of their telescopes, they say bigger is better. Explain why.
a) A wider aperture can observe a significantly larger portion of the sky. b) A wider aperture makes a telescope easier to aim. c) A wider aperture allows a telescope to collect more light, so it can produce images with higher resolution. d) A wider aperture allows a telescope to collect more light, so it can detect fainter light sources.
A new optical imaging satellite is being designed for the Maritime Domain Awareness mission. The satellite will be placed in a circular orbit at 5000 km altitude and be able to look off of nadir, giving a maximum range to the target of 7000 km. The desired resolution is 3 meters. What is the satellite's speed? Express answer in km/s to two significant digits.
