This episode did not air as scheduled at 22:00 tonight, July 21, 2024, because of CNN's continuing coverage of President Joe Biden's withdrawal from the 2024 US presidential race, which was announced during the afternoon. I deleted the airdate of July 21, 2024 and recommend this episode listing remain until it is rescheduled. That will save time re-entering everything.

Retitled, this episode re-aired on 6/2/2021 as "The New Explorers" without changes except for the title. It highlights missions to explore Pluto (New Horizons), the Hubble Telescope (repair), asteroid Bennu (OSIRIS-REx), Mars (Curiosity), and Saturn (Cassini). 

I deleted Kaitlan Collins as Host in this episode since The Source with Kaitlan Collins did not premiere until July 10, 2023. 

This July 10, 2024 episode marks the one-year anniversary for the premiere of The Source with Kaitlan Collins. She reviews her year at the end of this episode.
