Space-based radio telescopes are complementary to ground-based telescopes similar to how telescopes that study different wavelengths of light are.
1:46:46 - 1:48:11 (01:25)
Summary
Space-based radio telescopes are complementary to ground-based telescopes similar to how telescopes that study different wavelengths of light are. The exceptional engineering that goes into creating a space-based telescope involves three satellites separated by hundreds of thousands of kilometers communicating with each other through laser beams.
