The science ship Edward Israel is named after astronomer and polar explorer of the same name, who joined the ill-fated Lady Franklin Bay Expedition in 1881 where he received the assignment of collecting astronomical, magnetic and meteorological data. After the resupply ship in 1882 did not arrive, supplies ran out in August 1883. He died in May 1884, three weeks before the rescue mission reached the expedition.
Meeting with his Mother on Earth, Holden's mom hands him a copy of Don Quixote. There have been several references to the works throughout the 1st three seasons, including the name of their ship Rocinante, which was the name of Quixote's horse.
The Rocinante is officially its own ship. Formally declared a legitimate salvage. The crew even have suits that say "Rocinante" on the. This was done through Avasarala's help in the negotiations with Mars.
When the crew disembark of the Rocinante, it is possible to see the name of the ship on Naomi's bag : Tachi (the first name of the Rocinante).
