Okay, I am going to go ahead with the project. The first post will be Saturday, the 50th anniversary of the launch. The plan is to post two questions per day, for each of the seven mission days. The expected posting time is noon in Houston (17:00 UTC). I have a considerable list of questions, and have picked the ones I think people will find most interesting and fun.
For the majority of the questions, I already know the answer. My personal belief is that others should get the opportunity to write the answers, and I don't like answering my own questions unless absolutely necessary.
I've had a few questions in the past which have an interesting premise, but a difficult-to-find answer, and it's clear that I already know the answer. People complain "why don't you just post the answer", and once I do that, the question is then well-received. There are two questions like this, so I'm just going to immediately post those two answers myself.
However, there are a small number of questions that I don't personally know the answer, but I'm sure one of the regulars here can answer it.
There was one vote, in favor of posting those questions in advance. So here are the questions that I don't already have the answer:
- Why was 65 volts used for ground support equipment? (the O2 tank heater switch was not rated for this voltage)
Had Lovell's entire crew been grounded, who would have flown Apollo 13? (I believe the answer is in Deke Slayton's autobiography, but I don't own a copy.)
Without the accident, would Apollo 13 still have been the farthest manned mission?
- What trajectory would Apollo 13 have taken if the descent engine also failed? (what's shown in the movie doesn't count)
- How much delta-V would an Apollo 13 direct abort have taken? (if immediately done after the explosion)
- Did any part of the Apollo 13 LiOH adapter return to Earth?
Orbital mechanics (#3, 4, 5) is particularly an area where I need help.
If you're able to help answering one of these questions, let me know which number(s). I have a slight surplus of questions, so knowing which ones can be answered helps. Thanks.
