Imagine it.

did we really drive this far away on the later moon landings?

LMP: ..."It's ORANGE!!!"
LMP: "Orange soil!"
CDR: "Really?"
LMP: "Yeah, it's ORANGE!"
CDR: "Don't move it until I see it."
LMP: "I stirred it up wtih my boot! :D "
CDR: "It is! It's ORANGE!"

Furthest drive, furthest distance from a pressurizable spacecraft. EVA-2 remains the supreme achievement in extravehicular activity.

First human to perform EVA: Alexei Leonov, Voskhod 2 (recently died)
First American to perform EVA: Ed White, Gemini 4
First person to perform two EVAs: Mike Collins (Gemini 10, including one stand-up)
First person to perform three EVAs: Buzz Aldrin (Gemini 12, including one or two stand-ups)
Most EVAs during Apollo: David Scott, 5
Furthest distance from pressurizable spacecraft (the LM) during an EVA of any kind: 7.6 km, Apollo 17, EVA-2. The pic is from EVA-3, the final moonwalk (different angle, not the same event), but it gives a sense of scale. This is maybe about five klicks out or so.
Only EVA to have three people outside all at the same time: some Shuttle mission from the mid-90s where they physically grabbed a giant satellite with their "bare" hands.
Only "deep space" EVAs: 3. The CMP retrieved film surveying equipment from the exterior of the CSM during the trip back, on Apollo's J-missions.

Apollo entailed "untethered" moonwalks in the sense that the astronauts had no phsical connection to their spacecraft, but were still tethered safely by the Moon's gravity, of course. Apart from these, there have only been seven untethered spacewalks: the MMU EVAs from the early shuttle days, and a final SAFER test on STS-64 in 1994. Untethered is cool of course but they realized that robotic arms are vastly more practical for spacecraft assembly/maintenance.

Go to 9:20 for one of the ballsiest things ever done by a man (look at that spinning top he's advancing toward):

I WAS STROLLING ON THE MOON ONE DAY! IN THE VERY MERRY MONTHOFDECEMB-MAY!

MAY!

Some good quizzes:

Name the Apollo CSMs and LMs, by their official call signs/nicknames:
