Cygnus Readies for Flight to the Station
Published on Aug 19, 2013
Orbital Sciences' Cygnus cargo craft is bound for the International Space Station on a test flight. This flight will prove Cygnus' ability to rendezvous with the station and be captured by the crew on board. Once this is completed, the Cygnus will join the station's current fleet of cargo vehicles delivering supplies to the crew in space. This test flight is also the final set of milestones as part of NASA's Commercial Orbital Transportation Services (COTS) program.

What is the size of the hatch, by the way?
37 by 37 inches
Is there any discussion about using a full sized hatch on Cygnus?

That was asked at one of the pressers this week (there's video of both of those); if I recall correctly, Mr. Culbertson said that they could do that (with the impacts that would have), but that they haven't got a request for it. Space Pete posted something related in another thread:

Thanks, "Curioser and Curioser" I always thought the developers were supposed to think beyond current mission requirements. This is a trend with ISS, No Node-4, CBM hatches smaller than the standard, budget year by year the list goes on, but I digress... Thanks again.
Is there a thread for Cygnus Double CPM?

No, quite the opposite. There is no money for anything beyond approved requirements and cost is a driver, so items don't have excess capabilities. Not a trend, been that way for a long time.
Budget, year by year is nothing new. It has always been that way.

Actually, you could argue the smaller hatch not only meets the current requirements, but also cuts down on the weight of the PCM structure, so that the Cygnus can actually carry more cargo. Do you want to sacrifice cargo capacity for a larger opening that is not needed on 99.9 percent of the flights ?

I don't know, I just read to many articles about how if Wigit "A" had more capability, we would not have to replace it with an all new Wigit "B", it comes back to "why buy one when you can buy two at twice the price?".
Budget year by year, yes it's always been done that way. But I can't help asking myself, "Is there a better way?" Seems like agencies always end up fighting over money, and getting less of it every year.
Thanks for the input... Back to updates, what's new with ORB-D, how are the checkouts going?

They make them new each time anyway. If they need one with a bigger hatch, they can certainly get it.

http://andrews-space.com/news-blog/2013/10/2/andrews-space-delivers-four-more-cargo-module-power-units-to-orbital-sciences-corporationOctober 2, 2013
Andrews Space (Andrews) announced today that they've completed on-time delivery of four more Cargo Module Power Units (CMPUs) to Orbital Sciences Corporation (NYSE: ORB) which supply power to payloads aboard Orbital's Cygnus cargo logistics spacecraft.
The CMPUs provide up to 150 Watts of 28VDC payload power to mid-deck locker payloads destined for the International Space Station (ISS) aboard the Cygnus cargo vehicle. These units will be used on Orbital’s first operational cargo resupply mission scheduled for later this year.Is there a thread specifically for the CRS-1 mission?

Laws would require to be changed to change the budget process.
You can't spend more money than you have and you can't spend it on requirements you don't have at the time.

And the most perverse part of how the budget cycle works is a phenomenon we in the private sector have always called "Christmas In July".
If you don't spend all of you budget you get less the following cycle. So at the end of the budget year (often July for academia and September for government labs) if you have extra money, you go on a massive buying spree in an effort to spend every cent. The most perverse part is the organizations that engage in this tactic, often do it in panic mode $$$ ChaChing ChaChing $$$ willing to pay extra $$$ ChaChing ChaChing $$$ to get the order onsite before the end of the budget year.
Like I said, if you are a seller/manufacture of research equipment, it is "Christmas in July".

Of course, next year's budget is based on how much you spent this year. It's hard to justify a request for additional funds if you didn't spend that much the previous year.
Then we have customers with the attitude : My expenses for this year look bad already. I might as well move some of next year's expenses forward to make next year look better.

Has there been any movement on the inflatable heat shield concept for Cygnus? I remember reading about it sometime ago. Nice to have more downmass capability besides Dragon. Concept is similar to this.

In the evening on thursday I saw in Turin at TAS-I through a window 3 or 4 Cygni (I hope the adopted the real latin plural). During day the window was too dirty to have a look, but in the evening at 7pm it was dark outside and with the light inside it was a nice few. They had to work late. So there are enough in the pipeline for a few more launches.
