Houston, we have a problem...

Apollo 13 anniversary!

TLAM Strike · 04-12-10, 08:02 AM

Its also the anniversary of the Vostok 1 Mission.

razark · 04-12-10, 08:42 AM

And STS-1!

Task Force · 04-12-10, 09:16 AM

Yay for space travel!

Cool stuff. (didnt realise so many missions launched in the past today.

I'm old enough to have been alive and watched on our black and white TV as man took his first steps on the moon.

We all owe a huge debt to the brave men and women of the space programs.

It's a shame that we seem to be moving away from this sort of exploration.

About the only thing I remember from the MSI in Chicago other than U-505 is the NASA exhibit. They had Lovell's Apollo 8 command module there.

He is one of my heroes.

The command module of Apollo 13 is currently in an awesome space museum(The Cosmosphere) in Hutchinson, Kansas, not too far from Wichita.

Well worth the visit if you are ever in the area. I've seen the museum a couple of times when I was out that way for work(

...I'm heading out there next month. Might have to check it out again).

The museum traces the history of space flight from the end of WWII to the present in a very well thought out presentation.

The museum is also home of the Libert Bell 7(??)-the Mercury capsule that sank in the Pacific before they could recover it after the hatch "just blew" after Gus Grissom's flight. I remember quite a few years ago when they found it, recovered it, and the museum restored it.

The Liberty Bell 7 was lost in the Atlantic, not the Pacific. They didn't recover the hatch, which could have finally put to rest the question of why the hatch blew early.

I've been watching the tv series "from the earth to the moon". Its really good if you haven't seen it.

For those that have never seen these , they are some of the photos of the service module taken by the crew!

apparently one of the scenarios the crew did in their prep for the mission was having to use the LEM as a lifeboat -no one ever really thought it would be used so it wasn't done that often!

Platapus · 04-12-10, 06:45 PM

I always wondered if Vostok 1 really completed one full orbit.

Launch was at 45 degrees 55 minutes North 063 Degrees 20 Minutes East
Landing was at 51 degrees 16 minutes North 045 degrees 58 minutes East

Since his flight was east-west, let's ignore the latitude for a moment.

Which means he landed about 18 degrees West of his launching point about 540 NM short of his launching site. So in traveling East (as his flight did) he completed not a 360 degree transit, but only a 342 degree transit as measured on the ground.

http://en.wikipedia.org/wiki/File:Vostok_1_orbit.png

Now in actuality, since the earth was rotating to the east in the same direction as his flight, he traveled more than 360 degrees. In fact he traveled 372 degrees or 1.2 orbits.

However, under the FIA's requirements, only suborbital flights use rotating earth models.

That and the fact that Gargarn's ejected from the spacecraft would have invalidated the record.

But, in any case, it was a pretty brave mission

Keep in mind that this was the first time anyone had actually seen the damage. While in the LEM and Command Module, the crew couldn't see the side of the Service Module. There were no cameras to take pictures, no space walks, no telescopes or other spacecraft. They only knew what wasn't working. This was their first time seeing how bad the damage really was.

The thinking was along the lines that if anything went so bad that the Command Module wasn't able to support the crew, there probably wasn't a crew left at that point; if there was a crew, they probably wouldn't make it back to Earth.

A truly amazing story.

Just because he didn't go for one full orbit doesn't mean he wasn't in orbit. If the retrorocket hadn't fired and brought him down, he would have drifted in orbit for a while. The spacecraft was stocked with provisions for several days to allow a natural orbital decay to bring him down.

They did work out it out. They came to the concusion that it was the external hatch release cord had come loose. The redesign for the apollo missions was one of the reasons that the Apollo 1 crew was killed (they couldn't open the hatch fast enough)

The loose lanyard was Grissom's theory of what happened, and was accepted by some people, including Pad Leader Guenter Wendt. However, there was never a conclusive answer as to what really caused it.

But yes, the incident did lead to problems with the hatch of Apollo 1, including Grissom. Even if they had been able to undo the bolts and unlatch the hatch, they wouldn't have been able to open it against the pressure in the spacecraft, because the hatch opened inward.
