Astronaut Richard Gordon, 88, has died
R.I.P. Astronaut Richard Gordon, who piloted both a Gemini and an Apollo mission in the 1960s, has passed away at 88.
I described one of Gordon’s spacewalks during his Gemini 11 mission in 1966 as follows:
When he opened the hatch, both he and everything unfastened in the capsule was sucked toward space. Pete Conrad had to grab a leg strap on Gordon’s spacesuit to prevent him from drifting away. Later, Conrad had to pull him back using his umbilical cord. The arduous nature of the work caused both Gordon and his spacesuit to overheat, leading him to terminate the firs spacewalk after only 33 minutes.
On Gordon’s second and last flight on Apollo 12 he remained in orbit while Pete Conrad and Alan Bean went down to the surface, the third and fourth humans to walk on another world.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Gemini 11

The main purpose of Project Gemini was to learn all that was needed to perform the Apollo missions, including orbital maneuvering, rendezvous, docking, and working outside the spacecraft. Ed White’s excursion did not require any actual work, so he had an easy time of it (perhaps fooling the planners for future missions), but many important lessons were learned from subsequent spacewalks, because it turns out that it is not as easy to work in zero G as one would think. Everything takes longer than in the movies.
wayne’s video, above, tells about the one-orbit rendezvous of Gemini 11. The reason it was needed for Apollo is because the LEM Ascent Module coming from the lunar surface was going to rendezvous with the Apollo mother ship shortly after lunar launch. Many rendezvous (this is also the plural) took a couple of days or so, but the Russians are now using a “fast Rendezvous” that takes six hours (about 4 orbits).
For those who are seriously curious, I came across this article, which uses a little humor and very little math, to explain rendezvous.

Notice that Gemini 11 and/or its Agena target craft would have had to use a “dog-leg” maneuver to get it into the correct orbital plane for rendezvous.
As an aside, Figure 9 is the kind of thing that we used in my orbital mechanics class to examine rendezvous (a math intensive calculation, using partial differential equations in three dimensions).
Sorry for the pedantry, but shouldn’t it be “both a Gemini and an Apollo…”?
Judy: No apologies required. Pedantry appreciated! My grammar has been fixed.
