In 1975, Sagan, who was already famous at that time, was so impressed by Tyson’s college application that he personally reached out to him, hoping to convince the high school student to attend Cornell. He even offered to personally show Tyson around his lab.
Sagan’s letter, dated November 12, 1975:
Thanks for your letter and most interesting resume. I was especially glad to see that, for a career in astronomy, you intend to do your undergraduate work in physics. In this way, you will acquire the essential tools for a wide range of subsequent astronomical endeavors.
I would guess from your resume that your interests in astronomy are sufficiently deep and your mathematical and physical background sufficiently strong that we could probably engage you in real astronomical research during your undergraduate career here, if the possibility interests you. For example, we hope to be bringing back to Ithaca in late calendar year 1976 an enormous array of Viking data on Mars both from the orbiters and from the landers.
I would be delighted to meet with you when you visit Ithaca. Please try and give as much advance notice of the date as you can because my travel schedule is quite hectic right now and I really would like to be in Ithaca when you drop by.
With all good wishes,
