SpaceX Tuesday...
Discussion
SpaceX has been working with the US Air Force to customise the Falcon 9 rocket for their requirements. The resulting "Falcon 9 Upgrade" has now been certified for national security missions. So basically putting communication, recon, early warning, weather and GPS satellites into orbit.

they have been working hard on all fronts for this, ULA will be spitting teeth!http://www.losangeles.af.mil/news/story.asp?id=123...
that's their monopoly on the most lucrative launch customer gone.
As it should be too.
Back in the early days of the US space programme there were multiple launcher manufacturers providing lots of alternatives -
Boeing
Douglas
Convair
Martin
Lockheed
In more recent decades, because of mergers and consolidation within the industry, the number of competing launcher manufacturers has declined. It's good to see an element of competition returning.

Eric,
I'm not sure that's entirely true, back in the Apollo days, they were hardly in competition with each other they had so much work it was basically shared out between themselves.
There was a lot going on back then, not just Apollo.I'm not sure that's entirely true, back in the Apollo days, they were hardly in competition with each other they had so much work it was basically shared out between themselves.
With very few exceptions (the Gemini spacecraft being one), ALL NASA, and DoD projects had to, by law, be put out to competitive tendering between the different manufacturers. Of course, there were and still are allegations that not all these projects were allocated fairly but certainly the selection process was supposed to be competitive and fair and in most cases, more than one manufacturer would submit a tender.
Read "The Man Who Ran the Moon" by Piers Bizony for an insight into how the various manufacturers were selected for Apollo.

As with all suppliers they will sweat an asset as long as they can but whenever there is a step change in technology when a new technology comes along others will soon catch up there maybe some casualties along the way but not all competitors will collapse its not in the interest of the customer as the customer would only have one supplier and that is never good.

that's not the sign of healthy competition is it?
Question for you clever chaps - on the last SpaeX launch, it delivered 11 satellites into orbit.
How? How does a launch actually deliver 11 different things, presumably not all 11 go at the same time otherwise they all be grouped together. It must have some sort of system but i can't find any info anywhere.

it launched 11 small satellites in sequence (3 at a time), the video shows this in pretty good detail.
this is not that unusual, although 11 is quite a lot. Usually this sort of stuff is usually low earth orbit small stuff like globalsat etc.

The satellites are only 1m x 1m x 0.5m in size and 172 Kg in mass.

Because they were launching an odd number, to help balance on the rocket they used a "mass simulator" i.e. a weight.
Since the launch, the satellites have been slowly spreading out to cover their assigned areas. As shown from these maps from the CEO of Orbcomm:

well, considering we are talking Boeing and Lockheed, what do you think?ULA is Boeing and Lockheed, and no, neither of them are likely to "collapse"
Another barge kaboom sadly

Tantalisingly close though.
Amazing how the thing just turned into a cloud of vapour (a split second before exploding) as soon as it touched the deck of the barge!

Are you sure it was 3 at a time 3 in to 11 doesn't go.................(I know I will get my coat)https://youtu.be/O5bTbVbe4e4

Why is 11 quite a lot who says? Planet Labs Cubesats Deployed 28 from ISS with Many More To Follow - See more at: http://spacenews.com/39459planet-labs-cubesats-dep...
surely it depends on the nature of the array and experiment or use they are being put to

was not all 3 at a time, but they had to release them as pairs or 3 (one was dummy) to balance the ejection.Why is 11 quite a lot who says? Planet Labs Cubesats Deployed 28 from ISS with Many More To Follow - See more at: http://spacenews.com/39459planet-labs-cubesats-dep...

as for cubesats, they are tiny:

A CubeSat (U-class spacecraft) is a type of miniaturized satellite for space research that is made up of multiples of 10×10×11.35 cm cubic units, has a mass of no more than 1.33 kilograms per unit, and often sees the use of commercial off-the-shelf (COTS) components for its electronics and structure.
the orbicon ones were some 176Kg's each.Eric Mc said:

I don't think the completion of the Space Shuttle contract did Rockwell any favours, but the peace dividend in the 1990s probably had more of an impact on what had the largest defence contractor. Rockwell built the Shuttle orbiters and the Apollo command and service modules. They've since been broken up and sold off to various companies. The defence and aerospace business being bought up by Boeing.Gassing Station | Science! | Top of Page | What's New | My Stuff
