Because Iridium's constellation covers the entire globe, AMPERE can keep an eye on the planet form all angles at all times. That's reassuring; severe solar activity could potentially knock out satellites, cripple electricity grids and electronic devices on the ground, and even down, and even put high-altitude aircraft in danger. Moreover, solar weather occurs in cycles, sort of like hurricane season here on Earth. As it happens, we just entered a particularly stormy part of that cycle, and the next 3-5 years will likely be tempestuous.
