I think he used horses as a reference to the unit of work, horse power, but in this case instead of being the 550 foot pounds per second, it is the force required to put a horse at that altitude 199.27.128.195 08:10, 17 December 2014 (UTC)

The top one clearly says "Spacecraft mass" and the bottom says "Capacity" (which is normally either the mass or volume something can hold), so I don't think either refers to force. 173.245.54.175 08:32, 17 December 2014 (UTC)

Horses might also be used as a length unit... I am wondering if this is somehow related to the size of SRBs [1] ;-) -- Ld75 (talk) (please sign your comments with ~~~~)

A few mass calculations: (All masses from wikipedia)

• ISS - 450,000 kg / 932 Horses = 483 kg/Horse
• Skylab - 77,088 kg / 171 Horses = 450 kg/Horse
• Mir - 129,700 kg / 286 Horses = 453 kg/Horse
• Shuttle Payload - 24,400 kg / 54 Horses = 452 kg/Horse
• Compton GRO - 17,000 kg / 38 Horses = 447 kg/Horse

It looks like Randall probably used 450kg as a standard horse, which seems like a fairly average weight for a horse. --Pudder (talk) 09:06, 17 December 2014 (UTC)

Curious: the Atlas-Centaur rocket is listed as lifting Centaurs, not horses. 141.101.98.244 09:11, 17 December 2014 (UTC)

The Keyhole captions are wrong; assuming 450 kg/horse, 40 horses for the Keyhole 7 would be around 18,000 kg. Documents declassified a couple of years ago give the mass as around 2,000 kg. The Keyhole 3 was even smaller. The mass and dates are about right for Keyhole 11 satellites but I don't know where the 3 and 7 have come from (the dates are wrong for the third and seventh Keyhole 11s) 141.101.99.85 09:43, 17 December 2014 (UTC)

Initially I thought that the position of 'T Rex' along the X axis (approx 1985) may be a link to the band T.Rex, but according to wiki that was 1967-1977. I guess it could be a random date, but thats not usually Randall's style... --Pudder (talk) 10:51, 17 December 2014 (UTC)

The T Rex "Sue" was discovered in August 1990. Not quite right, either. 108.162.250.214 11:10, 17 December 2014 (UTC)

The Oldsmobile is probably a reference to the movie Mom and Dad Save the World. The title characters' station wagon was from around that era -- and it did go into space in the movie. --Aaron of Mpls (talk) 11:47, 17 December 2014 (UTC)
