Apollo 17 EVA-3 Station 9 - Five More Minutes
Spacecraft Films' Apollo 17 DVD No. 5 - EVA-3 - Station 9 - 33:02 to 37:38 (Heavily edited)
Not so much a joke, but good humour when time constraints clash with a useful find. One of those times when the engineers are exasperated and the geologists delighted.
168:28:22 Parker: (After a great deal of discussion in Houston) Okay, 17. We'd like you to press on. We'll abort the radial sample. We'd like to leave here immediately, if not sooner, to head for Station 10…
...168:29:21 Cernan: Jack, you ought to get a scoop of that dirt, though.
...168:29:36 Schmitt: Yeah, we'll get a scoop of it.
...168:29:39 Parker: 17, we're anxious for you guys to get going.
...168:29:59 Schmitt: Come here, Gene, quickly. We can't leave this.
168:30:02 Cernan: What do you got?
168:30:06 Schmitt: This may be the youngest mantle over whatever was... thrown out of the crater.
168:30:13 Cernan: Take pictures of it. Bob, we've got to take 5 more minutes. We'll be right with you.
...[Schmitt - (Laughing) "It doesn't take much to get your enthusiasm back up. Because, all of a sudden, there's a whole different tone in my voice. It may be a combination of having seen something different and the fact that Houston's now put some pressure on us to get out of there."]
[Cernan - "It also shows that you've got to have someone on the spot to make a decision. They're saying get out and we're saying 'Sorry, guys, we're not going to get out for five minutes because we've got something we think is worthwhile.' That's the way you have to operate. The ground is an advisor; it's a flight planner; it's a lot of things. But you've got to make the decisions of what you're going to do with your time."]
...168:32:11 Cernan: You with us, Bob?
168:32:12 Parker: Roger. We're with you.
168:32:13 Schmitt: He's mad at us now.
168:32:16 Parker: How'd you guess?
[Houston has been discussing a possible extension at this station. However, the Flight Director is concerned about tired hands.]
...168:32:29 Schmitt: Bob, a possibility here is that this upper 6 inches of gray material, in here, is the latest mantling in the area and the light-colored debris may be what's left over from the (Van Serg) impact.
168:32:45 Parker: Okay, I copy. I understand. But we'd like to get you going. (Pause) In case you didn't get the clue.
168:32:51 Schmitt: I know.
168:32:52 Cernan: We're going.
As it turned out, they didn't go immediately. Houston changed its mind and cancelled Station 10.
