Don't think I've ever seen such clear footage of a re-entry.
You obviously don't remember the Apollo era then. The last few missions landed within a mile or two of the carriers - so the pictures were pretty good. They even had live images from circling helicopters.

But this is pretty good too - at a fraction of the cost and resources.

They now need to get it onto the recovery ship.

Just before my time, old chap smile
Don't recall seeing anything like the airborne shot of the capsule comming down through the air like that, before the chutes extended - but then I've not seen all of the missions.

Ustream is working perfectly if you are not on it.

Now floating correctly it seems. Super work so far. First ESA and now NASA. Been a good month.
And tomorrow evening they should be bringing New Horizons out of hibernation for its approach to Pluto. About 9pm I think

Have a trawl through youtube. A lot of the footage of the missions is now on there.

It's quite amazing what we were able to get even 40 years ago. Considering a few days earlier we had been watching live colour TV from the surface of the moon, showing live colour TV from the Pacific wasn't such a big deal.

The difference of course, is the "Immediacy" of it. With the internet streaming, this is almost like being there! An incredible achievement by all concerned ;-)

(and if anything, it makes what was achieved by Apollo all those years ago even more amazing. Lets hope this sort of personal and intensive media coverage gets the children of today interested in the Future of humanity in space)

It was pretty immediate back then as well - considering that much if it was shown live on TV.

Whole evening schedules were devoted to covering the Apollo missions - especially on the BBC.
By 1968 we had the geosynchronous communications satellites in orbit which allowed live coverage from the other side of the world - so from Apollo 7/8 onwards, it was possible to watch these events live.

It is designed to be reusable ( though I suspect this particular one will be thoroughly dismantled for inspection ) apart from the heatshield and thermal tiles, which need replacing after each mission

Yeah it was a generic term for space-boffins wink
Fair point about the launch window, I don't actually know how long they are for satellite launches etc. Obviously pretty tight for something like rendevous with ISS, but not sure for a general satellite. I guess they will want to make sure it's well clear of any others.
Depends on what the satellite is going to do. Communications satellites are usually being placed at a very specific point in space so their launch windows are pretty tight.

Probbaly not this one. But the plan is for the fully functionable Orion to be reusable.

And elements of the SLS rocket will also be reusable, such as the SRBs (which are developments of the ones used on the Shuttle). I'm not so sure about the first stage of the SLS though. It is powered by four Shuttle Main Engine derivatives. The SME was reusable but these will have to survive a plummet into the Atlantic and immersion in salt water - so may not be capable of being reused.

I wonder what systems they did have in this Orion? Manoeuvring and some Comms obviously. Life support though?

No.

They had various weights positioned in strategic locations to simulate the effect of instrument panels, seats and other internal fittings. The weight distribution inside the capsule affects the behaviour of the spacecraft as it re-enters so this was an important part of the test.

The main part of the life support system for the crew will actually be housed in the Service Module (just like Apollo). The service Module used on this flight was essentially a dummy - again with weights inserted to provide a reasonable approximation of the behaviour of the Service Module under various flight and orbital conditions.

The recovery team has been given the all clear to approach the capsule.

In Apollo days they would have been all over the spacecraft like a rash.

They seem to be taking a far more cautious approach with this one - probably because it's the first flight. They are a bit concerned about the non appearance of two of the flotation bags. I don't suppose they don't want those things going off with a frogman sitting on top of the capsule.

Plus, less need to rush if there's nobody in it.

True.

I was surprised nobody attached a flotation collar around the base. They used to do this on Apollo within minutes of splashdown. Maybe they are more confident with the seaworthiness of Orion.

Presumably with Apollo capsules they blew the hatch with it still in the water to get the crew out, no need to open this one so it'll float a lot better.

ETA: Thinking about it, didn't one of the Apollo or Mercury crew nearly drown?
