[0:07] be isolated from the air ground which
[0:09] will be continually fed
[0:12] uh in real time to the news center.
[0:31] Problem might at the moment is one of
[0:33] attitude and guidance in the spacecraft.
[0:36] Uh the with the power down, I gather
[0:39] Wally Schirra, who was with me, they are
[0:42] not able to determine their exact
[0:44] attitude through their instruments and
[0:47] therefore they have said they are
[0:48] navigating by simply
[0:51] viewing out of the window the
[0:53] terminator, the sun line on the moon.
[0:56] That's one of the things I did read,
[0:57] Walter. Now,
[0:59] you must realize we're all trained to
[1:01] look at the star pattern, the celestial
[1:04] sphere as we call it,
[1:06] to determine which star is a navigation
[1:08] star. We have 37 stars that are part of
[1:10] our computer program.
[1:12] They can be picked up out of the window
[1:13] and that's part of what you heard in
[1:15] this last transmission. So, a a crude
[1:17] attitude can be obtained initially with
[1:19] the stars.
[1:20] Then we have a device in the vehicle, be
[1:23] it the LEM or the command module. In
[1:25] this case, of course, they're using the
[1:26] LEM,
[1:27] to look at a known star. And that data
[1:30] can be transferred from a little optical
[1:32] sight. It's kind of fun. I developed
[1:34] that back in Mercury days. Uh to
[1:36] determine their attitude celestially,
[1:38] which is the inertial attitude we talk
[1:39] about. Now, if the LEM computer works
[1:42] properly, they can attach uh the same
[1:44] star by moving the LEM of the whole
[1:46] combination, LEM service module command
[1:48] module, with the LEM propulsion system
[1:50] attitude control to get a fix. Now, the
[1:52] reason that they need that attitude so
[1:54] precisely i
