To Whom it may concern, this might be in the wrong section but I don't know where to put it.
I have seen the moon move across the sky over the course of 2-3 hours but why did the moon move so fast last night at the launch.
2. Are there photos of thrusters l4d,l2d,l3d,l5d,l5l
and the same ones on the right side . I have only seen l4l,l2l,l3l,l1l,l1a,l3a,l4u,l2u,l1u even from an SSME change photos.
Thanks

Narrow angle camera.
Plus, the moon's apparent motion is faster than many people realize. It moves its own diameter about every two minutes. This is not easily apparent when watching the moon at night, even with a single landmark in front of the moon, because most people have an unconscious tendency to move their heads to keep the landmark aligned with the moon. Aligning two landmarks with the moon provides a reference to keep the head steady. (Or set up binoculars on a fixed tripod, or use a telescope.)

Here's a question that'll make Jim wince
When is an orbiter's birthday? I know PAO are going on the maiden launch date - and that's cool, we'll do likewise. However, I'd of thought it would have been maybe her first powerup at Palmdale or when the orbital first arrived at KSC on the back of the SCA?
How do the Navy work this? Commission date?

Or when the first piece is placed in the final assembly rig, equivalent to when a ship's keel is laid.

As these things go, today is definitely a big silver anniversary, but I think what it's an anniversary of is a matter of preference. (Not a big deal one way or another.)

I grew up in the L.A. area, so the rollout ceremonies and delivery to Florida were a bigger deal there. All the orbiters got their picture in the papers when that happened.

Was wondering why STS 131 is scheduled to carry 7 crew members where every other remaining mission carries 6?
Thank you.

Payload upmass requirements on the last missions require smaller crew sizes.

Hope this is OK, but for grins a couple of screenshots from maybe five seconds of a local news report during STS-5; the rest I missed. Unfortunately, this was the only tape I owned at the time and I was more focused on the mission (it was EOM day at the time).

There are three other mission after STS-131. As such, it's just not that much of a concern.
This might help explain it a little better.
http://www.nasaspaceflight.com/2009/02/sts-131-logistics-flight-baselined-by-prcb/The mission is already deep into planning and is a very complex logistics flight (which brings up a lot of supplies and upmass to begin with). The mission was baselined as a 12-day flight but because of everything that needs to take place on the mission they are extending it to 13-days to make sure the 7-member crew can complete all the objectives. Reducing crew size on that mission for the sake of upmass would not be a good move.
UPDATE: Also, STS-133 (the final flight) will only carry 5 crew members, not 6.

Does anyone know if there is a plan on the books in shuttle to do a planned prebank if needed for ascent performance? It gives about 800 pounds, IIRC, and Jon Harpold himself approved it.
I am thinking it might still be useful for some of the flights left. It wouldn't be surprised if some of them aren't bumping up on the max ascent performance to carry stuff to station. Even if it would allow us to carry more water up, that would be a plus.
Station needs to be stuffed full of supplies when shuttle is retired.

Didn't we do this topic a few weeks ago? I was whining about how you'd cope with an underburn if you'd already targetted for a prebank or something like that.

Sorry for the ignorance, but what's a prebank?

Prebank is a maneuver you do so you "fall faster" into the atmosphere. It's done between the D/O burn and EI, and it's just banking the orbiter so that the lift goes to the side instead of upwards... thus the orbiter falls faster... and you want to do that if you have a "D/O underburn" or in an AOA.

Presumably that means you *plan* for a deorbit underburn thereby freeing up OMS propellant for use on ascent, thus giving you more ascent performance?
