The Pluto episode of How the Universe Works was kind of awesome. Cryovolcanos are kind of awesome.

This is a topic dedicated to pictures, videos, articles, and discussion of all things related to space.

For instance, New moon discovered orbiting Neptune.

Was watching videos from a channel on YouTube called, Dnews, and was surprised to hear them say that a person, unprotected/no space suit, in the vacuum of space, can survive for like 15 seconds or so before you pass out.  Moreover, some chimps who were exposed to the vacuum of space for a minute made a full recovery and one died. 

 

Contrary to what you see in movies, you would not explode or get turned inside out.

 

Also, when they say you're blood and saliva will boil, all they mean is liquid is turning into gas, so you're not being "boiled" in the sense of a potato in a pan of water.

 

I guess my purpose for saying this is: dying exposed to the vacuum of space would certainly be painful for 10-15 seconds as the pressure within your body equalized to the vacuum of space;, but it wouldn't be as gruesome as you might think (thanks for lying to us Hollywood).

I watched Apollo 13 movie (3rd or 4th time).  I studied Apollo 13 disaster real articles ..... pretty much accurate after launch.  Myself big question: why not suited up on EVA suit after explosion?  Spacesuit (EVA) protect oxygen/CO2 levels and temperature control.  You know the most critical was temperature (avg. of 35 degrees) and oxygen/CO2 thing inside "lifeboat" environment.

 

BTW, the funniest quote IMO: :laughpound .

 

[US income tax returns are due in 2 days, but Swigert is 200,000 miles away]

Jack Swigert (Kevin Bacon): Uh, well, if anyone from the, uh, from the IRS is watching, I... forgot to file my, my, my 1040 return. Um, I meant to do it today, but, uh...

Sy Liebergot (Clint Howard): [back at Mission Control] That's no joke. They'll jump on him!

 

or else ...

 

Fred Haise (Bill Paxton): It hurts when I urinate.

Jim Lovell (Tom Hanks): Well, you're not getting enough water.

Fred Haise: No, I'm drinkin' my rations, same as you... I think old Swigert gave me the clap. Been pissin' in my relief tube.

Jim Lovell: Well, that'd be a hot one at the debriefing for the flight surgeons... Another first for America's spacemen.

 

Of course, Hollywood's exaggerate especially before launch ....

 

1. Very little protest on changing from Mattingly (measles) to Swigert.  Flight Surgeon guy=Highly respect=NASA God.

2. Swigert was portrayed a playboy guy.  Bachelor yes but not a playboy.  Jack was supposedly workaholic (practice, practice, practice ...)

3. Time frame.  On the film, Saturn rocket was still traveling between vehicle assembly building to pad via crawler-transporter ..... less than three days to launch.  Actually 5 months complete trip awaiting for launch (pad).

4. Batteries on spacecraft.  Not critical after shutoff radar heat, gimble, computer, etc.

That's interesting. The first time I read it I thought you said 15 minutes instead of 15 seconds, haha.

I think it was the Titan (or Saturn) episode of How the Universe Works where one of the nerds said you could walk around on the surface of Titan without a space suit. It would be like walking around in Antarctica, but with a oxygen mask on.

It takes time for your body loose consciousness from oxygen deprivation I would guess. Oxygen is being sucked out of you body and through your lungs. Various kinds of vacuums and decomoresions have been experienced. Pretty intersting stuff to read at the link.

Basically the closest Hollywood ever came to the real deal was way back: 2001 A Space Odyssey.

Mars is approx. 12.5 light MINUTES away. It would take around 6 months to reach Mars with a manned aircraft. These 'new planets' are 40 light YEARS away. It would take around 800,000 years to reach these places by a manned aircraft....Don't you think we should quit with the nonsense fantasy and $20B/year spending for NASA?

100 years ago powered flight was a fantasy.  Today air travel is so common EVERYONE does it. It used to take a year to sail around the world. Today you could legit circumnavigate the globe in two days - maybe one with good connection flights.

 

Do you really think we won't have technological breakthroughs that drastically cut travel time from here to other stars in the next century?  How will that happen if we don't strive to advance technology?

To think of the sustainable water needed, vasts amounts of rich soil, perfect atmosphere in regards to chemical composition, shields of radiation, perfect gravitational pull, plate tectonics, constant weather that is able to be livable by all forms of life there is no chance there is a civilization that is in any way similar to ours.

I'm not saying that, but I think it is crazy to think that people find it fascinating without knowing the true reality of it. Over 5 years they spend over 100 BILLION DOLLARS. I would rather put that into something we know of - Earth.

And NASA's budget is still like .4% of the budget.   It's not like they are getting a lot of money that could be used else where in the grand scheme of things.

You realize NASA is more than just things up there in space right? It's aerospace research and climate research. They've invented or have help bring many technologies to the public. Artificial limbs, memory foam, LEDs for medical use, aircraft de-icing, cordless vacuum, freeze drying, scratchless lenses, solar cells, water filtration, fire/heat resistant materials, and tons of other things we use everyday.

Saturn's tiny moon, Pan, was captured on March 7 during a flyby by NASA's Cassini spacecraft. The images captured during the flyby are the closest images ever taken of the moon which has an average diameter of only 17 miles.

Pan's prominent equatorial ridge gives it a distinctive flying saucer shape. The ridge is believed to be the result of material from Saturn's rings raining down on the moon.

Mars is approx. 12.5 light MINUTES away. It would take around 6 months to reach Mars with a manned aircraft. These 'new planets' are 40 light YEARS away. It would take around 800,000 years to reach these places by a manned aircraft....Don't you think we should quit with the nonsense fantasy and $20B/year spending for NASA?

 

100 years ago powered flight was a fantasy.  Today air travel is so common EVERYONE does it. It used to take a year to sail around the world. Today you could legit circumnavigate the globe in two days - maybe one with good connection flights.

 

Do you really think we won't have technological breakthroughs that drastically cut travel time from here to other stars in the next century?  How will that happen if we don't strive to advance technology? 

 

To think of the sustainable water needed, vasts amounts of rich soil, perfect atmosphere in regards to chemical composition, shields of radiation, perfect gravitational pull, plate tectonics, constant weather that is able to be livable by all forms of life there is no chance there is a civilization that is in any way similar to ours.

I was in Salt Lake City on business a while back and decided to go to the Clark Planetarium and they had some extremely cool stuff.

 

This is a picture of a live feed they have.  I have a couple short videos I took on my phone.  The videos are kind of impressive, but do not even come close to doing justice to what the actual live feed looks like.

 

A look at the surface of our star, through a filtered telescope lens:

I want to know how they keep the rubber on the wheels from degrading during space flight. It's cold enough to rupture tires in space, and that thing has been in that icy coldness for two years, but it landed on its rubber wheels just fine. 

 

It's clearly not the same material as we have on domestic car tires.  Wonder what it's made of.

The failure to condemn is necessarily the act to condone.

Tires are a black art. You can make them behave almost anyway you want by slightly tweaking the chemical compounds in the mixture, but you sacrifice other properties obviously. I've studied vehicle dynamics and some race engineering, and even those guys don't know what the hell tire engineers do half the time. That's arguably the most important part of a race car!

But really if there is no load on the tire its probably not going to crack. It's probably a couple steps up from a winter tire you get on your car.

I'm betting carbon nanotubes and non-gas filled, maybe some sort of foam.

Huh. You should go inform the folks at NASA that they've all been wasting their time and you've got it figured out.

 

I'm not saying that, but I think it is crazy to think that people find it fascinating without knowing the true reality of it. Over 5 years they spend over 100 BILLION DOLLARS. I would rather put that into something we know of - Earth. 

 

And NASA's budget is still like .4% of the budget.   It's not like they are getting a lot of money that could be used else where in the grand scheme of things.  

 

$100B isn't a lot of money? I'll mark that one down
