Visit to the Space and Rocket Centre in Huntsville.
To visit the Space and Rocket Centre in Huntsville was a dream come true. Quoc, my guide showed me around this fantastic facility and I was extremely honored. I even got to see the wonderful Docking Mechanism close-up! If you are visiting the Huntsville area this is an amazing museum and a must-see! The only disappointing thing was that I was too old for Space Camp!

Dr. Wernher von Braun and his rocket team first came to the United States in 1945 under a military contract to create ballistic rockets. They were sent to Fort Bliss, Texas to work on rocket development, but after inspecting the Redstone facilities in Huntsville which had been used during World War II for the production of pyrotechnical devices, they deemed it a better location and proposed a guided missile center. On March 21, 1950, the von Braun rocket team moved to Huntsville and joined a group of U.S. rocketry specialists. Together, they would go on to create some of the world’s first rockets and satellites to orbit the Earth, and ultimately, the Saturn V rocket that sent the American Apollo astronauts to the moon, achieving the ultimate goal of preeminence in space.
Dr. Wernher von Braun and his team of rocket scientists transformed Huntsville, Alabama, known in the 1950s as the “Watercress Capital of the World,” into a technology center that today is home to the second-largest research park in the United States and to the U.S. Space & Rocket Center (USSRC) with its world-class educational program, Space Camp®.
The transformation grew from the smoke and fire that birthed America's space program. It is here in Huntsville that:
Rockets were developed that put the first U.S. satellite into orbit and sent men to the moon;
Propulsion for the space shuttle was developed
Modules for the International Space Station (ISS) were designed and built;
America’s next great ship - the Space Launch System - is being designed;
Science on the ISS is monitored 24/7 at the Payload Operations Center at NASA Marshall Space Flight Center (MSFC).
During the final months that von Braun and his team of scientists were refining the giant Saturn V rocket that sent Apollo astronauts to the moon, he was also preparing to launch another important project: a permanent exhibit to showcase the hardware of the space program. Von Braun was director of MSFC when he approached the Alabama Legislature with the idea of creating a museum jointly with the U.S. Army Missile Command and NASA. The U.S. Army donated land, and the U.S. Space & Rocket Center® opened its doors in 1970. Since then, nearly 17 million people have toured the Center. Many of the more than 650,000 annual visitors are school students on field trips to their future. Dozens of interactive exhibits encourage guest participation, prompting one official to note: "Here, everyone can be an astronaut for the day!

Apollo 14 - Houston, we have another problem
มุมมอง 187K2 ปีที่แล้ว
This video shows the problems the crew of Apollo 14 had with the docking sequence which nearly caused them to abort their moon landing. There are a number of excellent videos already on this but I've tried to break it down using CAD Models, Design info and telemetry data. The detailed interior is from a scan of the command module available from the Smithsonian at: 3d.si.edu/object/3d/command-mo...
Apollo Docking sequence - Connecting the Command Module to the Lunar Module.
มุมมอง 497K3 ปีที่แล้ว
I made this video to hopefully help people understand the Apollo Docking System. I've read an unhealthy amount of documentation on the subject but I was frustrated that there weren't any animations to show the sequence. The first thing I did was collect photos of the probe and docking ring. this was helped when I contacted John Fongheiser at space1 who supplied me with some drawings of the prob...
That is the BEST description and animation of a very important subject I have ever seen.
I'm going to give you a thumbs down for the 5+ minutes of commercials at the beginning
I was surprised to find such an outstanding video about the Apollo docking system. Recently I questioned how the forward hatch could possibly allow access to the LM if the probe were in place. The animation of probe removal was a perfect explanation. 👍🏻
Lots of suspense even though I know the end result.
Still geeks me out how they done this. Goes to show what can be achieved when an entire Nation is behind a project.
Excellent.
The USA landing on the moon was greatest achievement of the Soviet space program.
That's the best explanation ever.
On the other side of the iron curtain, the Soyuz vehicle designed for the Soviet moonshot didn't have a docking tunnel, so the lunar lander pilot would have to spacewalk across. Seems much more dangerous.
Indeed it was.
AMERICAN MOON
I'll be waiting for the year 2037
So are all those lunar modules apart from Apollo Ten on the moon ?
Apollo 5, 9, and 13 LM's burned up in Earth's atmosphere
all ascent stages either burned up in our atmosphere or ended up crashing on the moon minus 10's which is now in a solar orbit and possibly 11 which could still be orbiting the moon
Apollo11 - Apollo 12 - aPollo credici.🤣🤣🤣 I BuffoNauti Qui-Quo e sono rimasti Qua! 🤣🤣🤣🤣🤣🤣 Gli Americani, hanno sterminato 100 MILIONI di indiani in pochi anni, facendovi credere con i Film western che i cattivi erano gli Indiani, e oggi voi credete che sono stati sulla Luna?
Brilliant presentation. Well done!
This is a wonderful video. I'm born & raised here, & I've been on a lot of tours since I was around 8 years old from school trips. I visited again in 2018 & was surprised that it was nothing like my childhood. I was enamored by Warner Von Brauns's desk & his workings on display. Seeing the life of science & space exploration at my fingertips was fascinating. I'm glad to have visited again. Now, I see there is more to explore now & I'm only 20 minutes away. Thank you for your video! ❤️
Thank you so much
Well blow my hat off , always wondered. Great video.❤
Great Video, thank you Kevin Hughes.
"speyas" sounds so much cooler than space
Bring Snoopy back to Earth, that would be an astonishing feat!
Late to the party here.. I read about this over-and-over Michael Collins book but could never quite "get it". First class. Thank you.
The command module was orbiting the moon at 5200km/h. To put that in perspective the SR71 blackbirds max speed is 3500km/h. So somehow they had enough propellant to accelerate to catch up to the command module.... The truth is man did go to the moon. However he never landed there
Science is hard for some, and that’s ok. We got it.
@@CSMSteel7 can you explain how the capsule took off vertically off the moon then rearranged its momentum and fire additional rockets to accelerate to 5700km/h to perfectly align with the lunar orbiter. Or maybe they just orbited the moon, faked the footage. The radio communication was real. Bear in mind, no one but those 3 guys were there to witness it. How many people went to the moon? Incl apollo 13 - 27 astronauts. How many landed.... Zero Because you are American, you believe your government would not lie to you about something that important.... Well, try Iraq... Did they find WMDs?
@@davidbarnard1409 it wasn't vertical for long. If you watch any of the launch footage you'll see them pitch over heavily very shortly after lift off so most of the propellant went into getting the orbital velocity.
Wow. A new kind of stupid.
thats actually hilarious, you can admit we went allllll the way to the moon but didnt cross the 100 kms left to get to the lunar surface lmao
First class presentation. Just what I was looking for. Thanks.
I remember watching this live as it was happening. Certainly added more interesting drama to the Apollo - 14 mission, along with the LEM abort threat issue prior to landing. Made my staying up late nights/early mornings watching the events as they were happening. RIP to the crew of the Apollo - 14.
Excellent work. I think this animation would have helped the astronauts back then too. 👍😎
I've always wondered how this worked. Thanks! Also maybe starship can capture apollo 10's lander. That would be cool. It would be the only flown lander to survive if they brought it back.
I made a point of seeing all three Saturn V rockets in Huntsville, Houston and Cape Kennedy. These should have flown as Apollo 18, 19 and 20. What a loss in exploration.

Interesting stuff. I'd love for you to do one on Skylab's troubles docking too.
That was amazing! Such a clear and interesting presentation. Well done!
Great video!
There is supposedly a small chance that the Apollo 11 LM is still in lunar orbit due to it being unusually stable.
One thing you left out was, where was the probe and drogue stored in the Command Module? They’re quite bulky in a ship that is already very cramped
About two days ago, I spent about an hour and a half talking to a space shuttle tech on the Saturn V computer system, and I was in Huntsville so all this was happening under a Saturn, but those engineers were 1000% genius. I’m a 14 year old, and I surprised myself on how much I kept up with him.
How could the lander find the orbiter after take off? How is it possible ?
My SWAG: Use mathematics to calculate its expected position, get close, then use radar and visuals.
The CSM (orbiter) is in a stable orbit. The LM has the trajectory in the computer. Since the moon rotates very slowly (29 days), even on a three day mission the LM will fly up close to the CMs orbital plane. The LM does a series of burns to reach an orbit below the CSM's orbit. Since a lower orbit is faster, they will catch up to the CSM. At a specific point, the LM computer fires it's engine and that brings it near the CSM. And, as in the previous comment, they use radar with all this.
Here are some equations necessary to know how to make two orbiting spacecrafts rendezvous. They don't take into account gravitational anomalies like mascons, or gravitational influence of other objects, but that's all I know, for more accurate equations you'd have to ask a professional. V = √(GM ÷ r) - to calculate the velocity in a circular orbit V = √(GM(2r2 ÷ (r1(r1 + r2))) - to calculate the velocity at periapsis (lowest point) of an elliptical orbit V = √(GM(2r1 ÷ (r2(r1 + r2))) - to calculate the velocity at apoapsis (highest point) of an elliptical orbit T = (2π × r) ÷ v - to calculate the period of a circular orbit T = 2π × √(a³ ÷ (GM)) - to calculate the period of an elliptical orbit V is obviously velocity GM is the standard gravitational parameter, or gravitational constant × mass of the object. For the Moon it's 4900 km³/s² R is the radius of the circular orbit, which is the altitude the spacecraft is at + the radius of the object it orbits R1 is the shortest distance between the objects in an elliptical orbit R2 is the longest A is the semi-major axis of an elliptical orbit, a line between apoapsis or periapsis and the middle of the ellipse So, let's take a look at the orbit of the CSM first, because it's much simpler - it's a circular orbit that does not change throughout the rendezvous. So to calculate the velocity all we need to do is: √(4900 ÷ (100 + 1737) = 1.63 km/s Now let's calculate the period: (2π × (100 + 1737)) ÷ 1.63 = 7081 s, around 2 hours Also, the angular velocity will come in handy later: 360 ÷ 7081 = 0.05°/s Now, the complex stuff; the orbit of the LM. First, the LM enters a circular orbit at an altitude of 16.7 km. Luckily, we'll only need the velocity this time: √(4900 ÷ (16.7 + 1737)) = 1.67 km/s Now, the LM needs to perform a Hohmann transfer to meet with the CSM. That means it has to accelerate to raise its apoapsis to 100 km, while its periapsis remains unchanged. So the velocity at the periapsis must equal: √(4900(2 × 1837 ÷ (1753.7(1753.7 +1837)))) = 1.69 km/s Therefore, the LM has to accelerate by 1.69 - 1.67 = 0.02 km/s, or 20 m/s Aside from that, we also need to know the velocity at apoapsis to know by how much we need to accelerate to circularize the orbit. √(4900(2 × 1753.7 ÷ (1837(1753.7 + 1837)))) = 1.614 km/s So, the LM has to accelerate by 1.63-1.614 = 0.016 km/s or 16 m/s Of course, we also need to know when to perform these maneuvers. To do this, we'll have to know the period of the elliptical orbit: 2π × (1795.35³ ÷ 4900) = 6828 s. This not only tells us how much time it takes to reach the apoapsis to circularize (3414 s) but also when to begin the earlier transfer maneuver, to enter the 16.7/100 km elliptical orbit. Remember the 0.05°/s from earlier? Now if we multiply it by 3414, we'll get 170.7. That means the CSM will only travel 170.7° by the time the LM travels 180°. Therefore, the maneuver will have to be performed when the CSM is 9.3° ahead of the Lunar Module. In summary, the LM has to accelerate by 20 m/s when the CSM is 9.3° ahead of it, then, after 3414 s accelerate again, this time by 16 m/s. Then all that's left are some minor maneuvers using the RCS to dock the two spacecrafts together.
Thank you for explaining this. All my life I wondered how it worked
THX, some more answers!
Nine months later a baby Saturn V is born
Excellent! Very clear and answered a number of questions I’ve always had about exactly how this worked in lunar orbit.
Great video, thank you so much. What is the date of the German night, so that I can plan my next visit there ?
The engineering is really cool. But this all took 6 years and only 10 practice runs before having everything work precisely at a place nobody has ever been before.
So, with all that thrusting - that didn't result in retrograde delta-v? That didn't necessitate compensating?
The TLI velocity was 10 km/s. The delta v they introduced was minimal.
This was all calculated in the 60’s with slide rulers. AMAZING!
What happens to the (discarded) S-IVB? It's also headed to the moon but, obviously, doesn't do any lunar orbit insertion burn. Does it leave the solar system? Generally remain in orbit around the sun? Or what?
Depended on the mission. Some went into solar orbit. Others were crashed into the moon to give moonquakes for the seismometers left by other missions. The stage did not have the ability to leave the Solar system.
Snoopy lives.
Keep videos coming man!
Dokin?
Up till now, the best explanation I've found for how this system works was in Michael Collins book 'Carrying the Fire: An Astronaut's Journeys' from 1974. This animation was LONG over due, and so very well done. Thanks... from all of us space geeks.
Yes, pretty well the same for me. It’s hard to visualize what Collin’s was describing, at least for me it was.
Why do 90% of TH-cam videos have foreign or computer generated narration voices? Do any Americans make TH-cam videos?
