1,000 nanosats attached to the tether. Each nanosat is a self-contained optical sensor
spacecraft, integrated into a 0.1 kg package. The sensor thus detects 1,000
wavelengths simultaneously. The sensor has a resolution as small as 40 cm on the
ground from GEO. Its field of view can be scanned over an area by tilting the ensemble
using MEMS FEEP thrusters on the nanosats, or libration modes can be excited in the
tether so that the field of view scans across a 2,000 km coverage area in a quasi­
random mode, eventually covering the entire area. These thrusters also serve for
stationkeeping. Its total weight is less than 900 kg in orbit, which can be reduced in
the future to 9 kg if Buckytubes are used to construct the system.
