Sky skimmers: The race to fly satellites at the lowest orbits yet

BBC

A new space race is unfolding just above Earth’s atmosphere, with companies developing high-altitude satellites to race in an untapped region. These sky skimmers offer potential benefits, operating between high-altitude planes and low-orbiting satellites. With around 10,000 satellites currently orbiting Earth at speeds up to 17,000mph, their sideways momentum counteracts gravity to maintain orbit.
