Apollo Block II Entry Monitoring System

First, let us define a few things for you. From Wikipedia:

The Command/Service Module (CSM) was one of two spacecraft, along with the Lunar Module, used for the United States Apollo program which landed astronauts on the Moon. The CSM consisted of two segments: the Command Module, a cabin that housed a crew of three and equipment needed for re-entry and splashdown; and a Service Module that provided propulsion, electrical power and storage for various consumables required during a mission. The Service Module was cast off and allowed to burn up in the atmosphere before the Command Module re-entered and brought the crew home. (There are) two versions of the CSM: Block I was to be used for unmanned missions and a single manned Earth orbit flight (Apollo 1), while the more advanced Block II was designed for use with the Lunar Module.

The Entry Monitoring System (EMS) provides a visual monitor of automatic Primary Guidance and Control System (PGNCS) entries and delta velocity manoevers. The EMS also provides sufficient display data to permit manual entries in the event of PGNCS malfunctions together with a command sent to the SCS for SPS engine cutoff. The delta velocity display can also be used as the cue to initiate manual thrust-off commands if the automatic-off commands malfunction. During rendezvous the EMS provides a display of VHF ranging information.

John Glenn’s In-Flight Instructions Used & Flown Aboard Mercury 6

https://natedsanders.com/LotDetail.aspx?inventoryid=43935

One-of-kind piece of space history flown with John Glenn aboard the Mercury-Atlas 6 “Friendship 7” – the first manned orbit of the earth by an American astronaut. These in-flight photo instructions were used by Glenn aboard the 20 February 1962 mission and feature both a chronological flight plan with detailed astrological markers (“+7′ CASSIOPIA/COUNT STARTS” and “+23′ ORION & MOON/UV PHOTOS COUNT STARS”), as well as fixed geographical landmarks (“LAKE VICTORIA/KENYA NAIROBI” AND “CHRISTMAS ISLANDS”). All data on the instructions was personally used by Glenn to confirm the capsule’s flight path during its 4 hour and 55 minute mission, instructing Glenn at which point to take photos in flight. Instructions also include an in-flight check list that covers such tasks as “Chng Film-Color Filter Out” and “STOW & R. SEQ CHK CET”. The document was attached to a bobbin at each end, forming a scroll that Glenn was able to move back and forth with his thumb during the mission. The long and narrow document measures 4.75″ x 42.5″, its ends trimmed to fit into the bobbin slits. The in-flight instructions were given by Glenn to Frogman Richard “Dick” Dunham of UDT-21 (Underwater Demolition Team) as a thank you memento for his work with Mercury 6; a precursor to Navy Seals, the UDT both trained astronauts for egress from the space capsule into the ocean and retrieved the astronauts after splashdown. The flight plan was then given to U.S. Navy veteran Justin C. Pollard by Dunham, who became a mentor during Pollard’s time in the Navy Bud/S School, Class 240. The document’s historical significance was confirmed by the John Glenn Archives at Ohio State University Libraries. Light creasing and wear, otherwise near fine. Additional provenance includes: (1) LOA from Justin Pollard; (2) 1959 photo of Dunham and Glenn together (Dunham is the blond gentleman, 4th from left in back row) and (3) screen-capture photo of the Mercury 6 cockpit, scroll visible in center of photo, in front of John Glenn.
