How the next Mars Rover will land on Mars
>> ^alizarin:
You'd think NASA would realize there's no sound in space.
I was giving them the benefit of the doubt. "The microphone is inside the spacecraft" I said.
They they had that flyby shot.

How spacecraft are shielded from space-junk collisions
>> ^charliem:
Idea!
Launch a satellite that's one gigantic electromagnet, leave it in orbit for 30 years...no more space junk!
Good thinking! But aluminium, which most spacecraft and thus also space junk are made of, is sadly not ferromagnetic, so the electromagnet would have no effect.

Fareed Zakaria Responds Beck's Terrorist Estimates
Powers of 10, they make a difference. The difference between going to the supermarket, and going around to the other side of the city is about the same factor he was off by. Or it is the difference between our position next to the sun, and the Voyager 1 spacecraft which is about to exit the solar system.
60 min News Has "Top Gear" on
It is a great show, one of my favourites, but for a couple of seasons now it's been feeling a little forced and contrived. The 'stunt' portions of the show seem more and more scripted and less and less spontaneous. The amount of stuff you have to figure they have pre planned and got permission for and organised for each of them now really takes the 'fun' out of those segments.
My favourite segment, still by far, is the one where they took a Reliant Robin and turned it into a spacecraft. You have to watch the whole segment, not just the final launch, to get the real feeling of amazing accomplishment that it was.
And sadly they have never come close to that for me again.
New York has a space program
The phone/balloon are held aloft by the atmosphere. The shuttle is doing orbital velocity and re-entering the atmosphere. The shutle's moving a lot further and faster. It's like the difference in energy between skipping a stone across a pond, or placing the stone gently on the surface of the water (actually a couple inches down in the water), and letting go.

So my major thought just now was the atmosphere..
although I will go and learn for myself, right now I wonder why they did not need head shields or anything like that.
Just where oh where does the atmosphere begin exactly/end exactly, Why does a space craft from NASA need some ceramic plating while this lil doodad needed naught but shaved expanding foam.
on a side note, I think it would of made the video better if in every frame that is shown whilst someone was in frame, they would of held a hot dog in a bun.
eta- "The atmosphere has a mass of about 5 × 1018 kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. An altitude of 120 km (75 mi) is where atmospheric effects become noticeable during atmospheric reentry of spacecraft. -wiki "

UFO Conference 9/29/10
The concept of life outside of earth ought to be part of everyone's reality. I don't know about alien spacecraft actually visiting us and shooting beams of light into missile silos. If aliens were studying us it'd probably be accomplised by something like remote viewing through a wormhole or some such. In other words completely undetectable. What I am almost certain about is that alien life must exist. To me, looking out at the universe and believing we're the only life that exists is like one speck of sand believing it's special and magical among all the other specks of sand in existence. The numbers are against the presence of life here being unique. Most likely, life is commonplace. And I believe that intelligence is simply the logical result of self-organizing biology... intelligence leads to greater energy capture which is the immediate purpose of biological self-organization. In most cases you probably only get one intelligent species on a life-bearing planet at a time, but there are more planets out there than stars. Which is to say, a lot of cases.
Back to the wormhole thing. There's a theory that, at some point in the future, humans will develop remote viewing technology. That is, the use of wormholes to peer through time and space, giving an undetectable *live view* of events from the past. Not exactly visiting the past, more like snaking a SWAT team camera through time via wormholes. Now, according to the rules of big numbers, given the existence of remote viewing technology in the future, and future extending for millions and billions of years... every single moment of every single person's life is probably being directly observed by someone in the future. Of course, more important moments are being watched by billions or trillions of people from the future. But on average, every moment is watched at least once. Think about that shit.
Arthur C Clarke wrote a book around this concept called The Light of Other Days. Needless to say, the ultimate, ultimate extents of the technology in the book are pretty mindblowing.
Lets Have a Space Day! (Science Talk Post)
I have been thinking and it would be cool to have it on a significant date related to space. July 20th is the anniversary of the moon landing but maybe its a bit close, I havent been able to dig up any great space videos to kick the thing off with, and Im not sure how many are interested "Build it and they will come" indeed but I can't find the proper building material
Here are some important dates:
July 20, 1969 First Manned Moon Landing
August 20, 1977 Launh of Voyager 2 (yes! it was launched before Voyager 1)
September 5, 1977 Launch of Voyager 1
September 12, 1959 First Spacecraft to Impact on the Moon
September 15, 1968 First Moon Orbit
October 1, 1958 NASA is Born
October 4, 1957 First Artificial Satellite
October 4, 1959 First View of Moon's Far Side
Anyone have some great ideas on how to attract some attention to a space day? Build up some excitement?

Awesome!!! NASA Team Captures Hayabusa Spacecraft Reentry
Don't stop giving your opinion, I won't (= cool.).
>> ^vaporlock:
I should have known better than to give an option. Sending a probe to an asteroid, landing, taking off again, and then crashing it into the skies above Australia is definitely cool...
Vampire squid turns itself "inside out"
Reminds me of the alien spacecraft from that Lifeforce movie in the 80s.
UFO? Missile? Rocket? Canadian Government Isn't Talking
It's a pet peeve. People use UFO and "alien spacecraft" as if they are interchangeable. Try telling someone "I saw a UFO" and see whether they don't chuckle at you.
FUCKING RETARDS.
