Astronauts Open Dragon Capsule Hatch
Hexydes writes "Early in the morning (5:53 am EST) on May 26th, 2012, NASA gave the go-ahead for the Expedition 31 crew to begin the procedure to open the hatch on the Dragon capsule, now directly attached to the ISS. 'The hatch opening begins four days of operations to unload more than 1,000 pounds of cargo from the first commercial spacecraft to visit the space station and reload it with experiments and cargo for a return trip to Earth. It is scheduled for splashdown several hundred miles west of California on May 31. Wearing protective masks and goggles, as is customary for the opening of a hatch to any newly arrived vehicle at the station, Pettit entered the Dragon with Station Commander Oleg Kononenko. The goggles and masks will be removed once the station atmosphere has had a chance to mix air with the air inside the Dragon itself.' Here is a video of the procedure."
Yeah except for the part where you're trying to stop the 1000 pounds of cargo trying to bash it's way out of the space
station part.
Also I'm guessing it's not just sitting on one pallet in the middle of the capsule.
IIRC, even if the gravity is 0 you still have mass and inertia to deal with. "Heavy" stuff will be harder to get moving and stop moving once it's where it's supposed to be. Also, with Newton's third law, even tossing something with fairly low mass will have an effect on your position. So you'd have to brace or bounce off a wall or something. That would probably make the logistics of unloading a large cargo fairly... interesting...
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
There is this thing called inertia, and it is a bitch, especially at 0 G with no/little friction to help. Once the 1000 pounds of stuff gets in motion it will bounce around the place until everything gets smashed to pieces.
It's not all in one box. Whatever it is has to fit through the hatch. Inventory, move (inertia!), stow. Now do it in the other direction for the stuff that needs to come back to earth.

I would have rigged up two things.
1 - a huge "planet express" sticker on every box.
2 - a small device rigged to play "never gonna give you up" 30 seconds after they open the hatch.
Come on, a futurama joke and a ISS rickrolling would be utterly epic.
Do not look at laser with remaining good eye.
Slow and gentle.
Press on a thousand pounds in freefall with a force of a pound, and in ten seconds, it's moving at 10cm/s.
This is probably faster than you want in a confined environment.
If you need more than your little finger to exert the pressure - you're doing it wrong.
Of course, that should read mm/s.
No thanks. They will make the seats tiny so they can fit 8-10 astronauts in there, plus charge $35.00 per bag. On top of that imagine 3 days in a capsule with only small bag of nuts, and not being able to use your ipad until you are above 150 miles.
Do not look at laser with remaining good eye.
Oh yes they do. The goggles are there to prevent....
S P A C E - M A D N E S S !

Unloading 1,000 pounds in microgravity requires the same energy as in 1G. 450kg however would be significantly easier.
I missed the live broadcast because the bastards opened the hatch an hour an a half early. The flight director, Holly Ridings, had warned they might be "a bit early" in yesterday's press briefing, but I had no idea they'd be that early.
Anyway, it's cool to have it all ship-shape and working fine. I was amused by Don Pettit's comment: "It smells inside like a new car!" ;-)

I have tremendous respect for Mr Musk and his team at SpaceX. To have designed and built the Falcon 9 and the Dragon, and to have them work perfectly every time, in the short time they had, is an amazing achievement.
On the other hand, this really isn't the first "privately built" spacecraft. Almost all of the "NASA" rockets and spacecraft were built by independent contractors. NASA did a lot of the design work on the Saturn rockets and the spacecraft, but the Redstone, Atlas, and Titan rockets were all designed by private contractors for the military. SpaceX has some advantage in that it's doing everything under one roof (literally).
It is impressive to see that hatch open -- showing the depths of the cooperation between NASA and SpaceX. NASA has to have been working on this almost as hard as SpaceX over the past year to develop the procedures for the rendezvous, capture, and berthing of the Dragon. The opening of that hatch might not be as historic as the Apollo-Soyuz docking of the '70s but it's right up there.
I love Mondays. On a Monday, anything is possible.
A Ren & Stimpy reference to go with your earlier Futurama reference (and in reply to a Simpsons reference)? <Mr. Burns>Excellent </Mr. Burns>
while there is no weight, objects still have mass and momentum so producing enough force to start moving 1000 lbs and producing enough to stop 1000 lbs is a big issue.
No. It is no issue at all. You could push it with your finger. A fly could move it. If you apply 10 pounds of force for one second, it will start moving, and it will take exactly 10 pounds of force applied for one second in the opposite direction to stop it... or you could stop it by applying 5 lbs of force for two seconds.
When our name is on the back of your car, we're behind you all the way!
It's great that we have U.S.-based cargo delivery/recovery capacity again. This is definitely a huge milestone. However, the crewed-version of the Dragon will be the true, emotional U.S. milestone, as it replaces the human element lost with the retirement of the space shuttle.

Not to mention being raped by TSA perverts.
Consider, a pallet sitting in the middle of a room in 0G (a MUCH easier setup than the tight quarters in the capsule and ISS). You grab the load and lift. Slowly it starts to rise from the floor (designated). It's high enough so you start pushing down and end up going for a ride on the cargo. Here comes the ceiling! CRUNCH!, squashed like a bug.
So, no. Not easy and not a 1 man operation.
In reality, the cargo is divided into many smaller packages in racks. It takes time to inventory ans stow all of that.
Actually, it's a non-union shop, so they are waiting for immigrant workers that they will immediately throw out the airlock instead of paying when they are done.

Greetings and Salutations;
Hum...I have, for years, wanted to see some of the outtakes from "Ice Pirates". It is a truly awful film, but, right after that line, there is a cut and from the expressions that remain on the actor's faces I suspect there was something terribly amusing and probably pretty crude that got said.
Now, I am going to have to get a copy of it and inflict it on some folks....Sigh.
Pleasant dreams

everyone is an immigrant on ISS..
The video narrator sounds like he should be piloting a terran battlecruiser.
For you are crunchy and taste good with barbecue sauce.
Have gnu, will travel.

Speak for yourself, mister.
Hahah, I get it!
After all your trips through the TSA chechpoints, you're left with a small bag of peanut butter.
Forget the immigrants. I want to know about the illegal aliens.
if you're strong enough to accelerate it you're strong enough to decelerate it provided you have enough distance to do it over; the processes are exact mirror images.

It's a darn good thing they don't have to show their passports every time they cross a national boundary.

Specifically, THIS Falcon 9 was disposable. At some future time, the first stage, and I think the second stage too, will land vertically after a powered descent, and will even have fold-out legs to land on. Only the "trunk" section behind the capsule and the solar panels attached to it are specifically not going to be reusable, because they reach orbit without a heat shield.
There are also plans for the crew capsule to do a powered ground landing, but that will make use of the enhanced maneuvering rockets that will be designed to work as a (non-disposable) launch abort system.
