Field notes

The page separates an observatory from a hangar-style mission area, with examples including eclipse viewing, local-sky conditions, and simulated re-entry heating. It lists missions spanning the Moon to Halley 2061 and describes hazards such as radiation belts, ring ice, and space junk. These are homepage descriptions; the extracted evidence does not establish how each feature performs in use.
