I. A. Oprescu,G. Burstein,F. Loewand reddened by the atmosphere. The Sun makes an excellent probe for studies of atmospheric effects; it is especially useful for studying refraction, extinction, and color effects that occur near the horizon and the polarizing property of the atmosphere.separate 发表于 2025-3-29 05:33:50

Orbits and Space Travel,nd to all but one of the known planets. In this exercise, we explore first the properties of planetary orbits, then how to calculate their coordinates on the sky from their orbital elements, and, finally, how to design the orbit of a spacecraft to travel to a target planet.
