In 1946, the American astrophysicist Lyman Spitzer Jr. proposed the concept of launching a large telescope into space. His groundbreaking idea laid the conceptual foundation for what would eventually become the Hubble Space Telescope.

What space telescope is named after Lyman Spitzer Jr.?

NASA named its infrared Spitzer Space Telescope in his honor, which launched in 2003. This space observatory was a vital part of NASA's Great Observatories program, alongside Hubble and Chandra.

Did Lyman Spitzer Jr. contribute to fields other than astronomy?

Yes, alongside his astronomical work, Spitzer was a major pioneer in the field of plasma physics. He even founded the Princeton Plasma Physics Laboratory to research controlled nuclear fusion as an energy source.

Did Lyman Spitzer Jr. live to see the Hubble Space Telescope launch?

Yes, he lived just long enough to see the Hubble Space Telescope successfully deployed into orbit in 1990 before passing away in 1997. He had been advocating for the project for nearly half a century.
