	Astronaut David Scott constrains the likely timing of the naming to March-April 1967, shortly after the January 1967 [https://www.nasa.gov/mission/apollo-1/ Apollo 1] fire.		Astronaut David Scott constrains the likely timing of the naming to March-April 1967, shortly after the January 1967 [https://www.nasa.gov/mission/apollo-1/ Apollo 1] fire. David Scott claims that it was the Apollo 9 crew (who were backup crew to Apollo 1) and Dr. Clarence Cleminshaw of Griffith Observatory, who originated the names:

			"''During the Apollo program, the crews were required to to identify and locate 36 stars for celestial navigation. Most of these stars had popular names, but, at the beginning of Apollo, three did not. Soon after the tragic Apollo 1 fire (about 2 months), the [[wikipedia:Apollo_9\|Apollo 9]] crew (Jim McDivitt, Dave Scott, and Rusty Schweickart)'' ''[who were backup crew for Apollo 1] were undergoing navigation star training in the Griffith Planetarium under the tutelage of Dr. Clarence Cleminshaw, the Director of the Griffith. During a break in Dr. Cs office, we began discussing the fire and the sad loss of the A-1 crew. Somebody (?) suggested that perhaps we should honor the crew and memorialize them by naming the three obscure Apollo navigation stars after them. But how to do that discretely and uniquely? A subsequent comment suggested that we reverse the order of letters in their name - but how? The group then explored several options and decided to use Gus’s middle name (Ivan, or Navi), Ed’s name title (Second, or Denoces), and Roger’s first name (Roger, or Regor). We recorded those in our informal notes and began to use them. Subsequently, they were recorded in the official NASA star list and became the names of preference in all NASA documentation. And I remember just how we arrived at the star names. First we wrote all three full names backwards. Then looking at them, the better sounding name was selected. Virgil Ivan Grissom – Ligriv Navi Mossirg, Edward H. White, Second – Drawde H. Etihw, Dnoces; and Roger B. Chaffee – Regor B. Eeffahc''."

			One might speculate that as a planetarium director, Cleminshaw would no doubt have been familiar with the [http://www.ianridpath.com/startales/delphinus.html infamous case of onomastic subterfuge with the reversed Palermo star names] in the constellation Delphinus ([https://archive.org/details/starnamesandthe00allegoog/page/200/mode/1up?q=Rotanev+Sualocin Sualocin, Rotanev]), which were commonly referenced in popular astronomy books of the era (e.g. Star Lore of All Ages (1911), Star Names: Their Lore and Meaning (1899, 1963)).

	In [https://www.google.com/books/edition/The_Griffith_Observer/lJJ-AAAAIAAJ?hl=en&gbpv=1&bsq=Apollo%20Regor ''The Griffith Observer'' edition of September 1967], Griffith Planetarium director [https://griffithobservatory.lacity.gov/about/observatory-history/directors-of-griffith-observatory/ Clarence Cleminshaw] mentioned the names Navi, Dnoces, and Regor for those three stars in a story on navigational stars. David Scott states that the Apollo 1 crew would not have trained with Cleminshaw in 1966 as Cleminshaw and Griffith Planetarium did not get a contract to train Apollo astronauts for star navigation until September 1966. The Apollo 1 astronauts left California to train at Kennedy Space Center in Florida in early September 1966, shortly after the AS-204 / CM-012 / Apollo 1 spacecraft was shipped (August 1966). David Scott's notebook from mission training in October 1966 listed three bright navigational stars (gamma Cassiopeiae, iota Ursa Majoris, gamma Velorum) that were the only ones of the 37 lacking common names.

	"''And this remembrance could very well been influenced by the three islands in Long Beach Harbor that were named in honor of Gus, Ed and Roger soon after the Apollo 1 fire.

Chaffee and two other astronauts, Gus Grissom and Ed White II, perished in a fire in the Apollo capsule during a launch rehearsal test on January 27, 1967. Their spacecraft, posthumously designated by NASA as [[wikipedia:Apollo_1|Apollo 1]], was supposed to launch in February 1967 to conduct the first test flight of the [[wikipedia:Apollo_command_and_service_module|Apollo Command and Service Module (CSM)]]. The star names '''Regor''', '''Navi''', and '''Dnoces''' -- backwards for "Roger" ([[wikipedia:Roger_B._Chaffee|Roger Chaffee]]), "Ivan" ([[wikipedia:Gus_Grissom|Virgil Ivan "Gus" Grissom]]), and "Second" ([[wikipedia:Ed_White_(astronaut)|Edward Higgins White II]], i.e. the second) -- started appearing on Apollo navigational star charts in 1967 for the stars designated gamma Velorum, gamma Cassiopeiae, and iota Ursa Majoris, respectively, and subsequently diffusing to popular astronomy works in the late 20th century.
 "''Unfortunately, as a result of these incorrect entries in the Journal, the origin of Navi, Dnoces, and Regor as a joke has been widely distributed in all forms of information on Apollo. The origin of these names was not a joke; the origin was intended to honor and memorialize three wonderful men who worked so hard to make Apollo a success and eventually gave all they had.

	Regor was one of three mysterious new names that started appearing around 1967 on American navigational star charts ~~during~~ the ~~early years preparing for~~ the NASA Apollo crewed lunar missions. ~~It is backwards spelled "Roger"~~, ~~conciously ambiguous~~ for the ~~term "roger~~" in ~~radio language~~ to ~~confirm that~~ a ~~message was received~~, and ~~for the first name~~ of one of the astronauts "R. ...".		Regor was one of three mysterious new names that started appearing around 1967 on American navigational star charts early in the history of the NASA Apollo crewed lunar missions.

			Extensive notes exploring the origins of the names and the parties involved are documented in the [https://apollojournals.org/alsj/a15/a15.postland.html#1051133 Apollo 15 Lunar Surface Journal: Post-Landing Activities] site (Eric M. Jones, 1996, last revised 2026) and a [https://apollojournals.org/alsj/a15/DRS2016memo.pdf 2016 memo written by Apollo 15 Commander David R. Scott] to Eric M. Jones for the Lunar Surface Journals. Astronaut David R. Scott states:

			"''Unfortunately, as a result of these incorrect entries in the Journal, the origin of Navi, Dnoces, and Regor as a joke has been widely distributed in all forms of information on Apollo. The origin of these names was not a joke; the origin was intended to honor and memorialize three wonderful men who worked so hard to make Apollo a success and eventually gave all they had. Dr. Cleminshaw himself recognized this as an honor in his 1977 book, [https://books.google.com/books?id=szIJAAAAIAAJ&focus=searchwithinvolume&q=Regor The Beginners Guide to the Skies]:''

			''“Navi (Gamma Cassiopeiae) is “Ivan” spelled backwards and was named in honor of Virgil Ivan Grissom, one of the three astronauts killed in the Apollo fire.” (Note: “in honor of…Grissom”, not “by…..Grissom”). (Similar entries are included for Ed White and Roger Chaffee.)''"

			Astronaut David Scott constrains the timing of the naming to March-April 1967, shortly after the January 1967 Apollo 1 fire. Scott's notebook from mission training in October 1966 list three bright navigational stars (gamma Cassiopeiae, iota Ursa Majoris, gamma Velorum) that were the only ones lacking common names.
