What is "regression testing?"
(See Cygnus status, SM regression testing was conducted 2/9/16-2/29/16)

In software, regression testing means retesting software that was previously working to make sure you haven't broken it with recent changes.  In particular, you want to test the system as a whole to ensure that changes you made in module A does not cause module B to malfunction.

To expand on regression testing, you normally keep a suite of tests that you know the results of from previous runs, and compare the results of new runs against the software you updated to make sure it works the same way, or if you expect a different behavior due to your updates, you get that new behavior.

Dunno how else to say this, but isn't naming this born to burn up on re-entry spacecraft after STS-107 Commander Rick Husband a little wrong? I've heard several other observers say the same thing.

Agreed.  I appreciate the sentiment, but I cringed.  The SAFFIRE payload doesn't help either. :(

EDIT: However, the S.S. Rick Husband is OA-6, not OA-5 as in this thread...

My thoughts exactly. This is why I think it is a bad idea to name spacecraft after people. Fortunately for ATV this worked out fine but I didn't like it being named after people either.

The Orbital ATK Cygnus pressurized module for the Orbital ATK CRS-5 mission arrives at NASA’s Wallops Flight Facility on March 8, 2016, to begin processing. Cygnus is scheduled to fly atop the Antares rocket to deliver supplies, equipment and science experiments to the International Space Station this summer from the Mid-Atlantic Regional Spaceport at Wallops.

I'm not sure what building that is, it isn't OA's HIF.

Slipping till 6/24

That's the same day as SpaceX CRS-9 and NROL-61. Three launches in one day?

Something will slip, a long way out to force someone to swap dates right now.

Would be nice for you Amerikanskis if an [sarcasm]all-American[/sarcasm] rocket like Antares launches on the 4th of July. Perhaps you'll even get to see some great fireworks!

All-American??.
IIRC they use an ukrainian first stage powered by 2 russian RD-182 engines.

And the cargo can is Italian. I was being sarcastic, which is hard to convey on the internet.

Pathfinder, Deep Impact, and STS-121 were pretty nice 4th of July shows.

Yep. And Viking 1 was originally a July 4, 1976 landing, if I recall right, but once they reviewed their landing site options, shifted to a July 20 landing---another great space day.

Some information from the quarterly earnings conference call May 5.  OA-5, OA-7, and a launch cadence of 2-3 CRS missions per year.

First of all -- Blake alluded to this in his comments -- we've got, I think, three big events relating to Antares this year. The first one will occur later this month. In fact, next week, we will roll out to the launch pad, the first re-engined Antares in preparation for buyer testing of the first stage and its new engines, which will occur later this month. That's the first milestone.

Assuming things go smoothly there, then probably on the order of six weeks later -- so that would put us around just after the fourth of July -- we expect to be ready to launch the first of two re-engined Antares rockets on a space station cargo mission, which we call OA-5. And then we will turn around about three or four months later, probably sometime in November, for a second Antares launch on another space station cargo run. So those are the three big events this year. All of the hardware necessary for the engine test, as well as the first two launches of the re-engined rocket, is at the Wallops Island launch base now. And so we are getting close to being back to flight-ready status.

Beyond this year, with the new extension mission added, and with the new CRS-2 contract coming on line, the base level of demand, really through the middle of the next decade, for Antares should run at two or three launches per year. And that gives us a solid foundation on which we can increase market reach of the vehicle, and flight rates as well. We designed Antares, like we do most of our launch vehicles, to represent good businesses for our customers in terms of schedule and reliability, and good businesses for us in terms of profit margin, at fairly modest launch rates.

And we do that by commonality across a broad range of target vehicles, missile defense interceptors, small space launch vehicles, and now with Antares medium-class vehicles, we use a lot of interchangeable parts and subsystems. We use the same engineering and manufacturing teams and facilities, and so as we go from two or three launches a year to five or six launches a year, there's a lot of operating leverage for us in that. Once we get back to flight status and put a couple of good launches behind us, then I think we will start to see some real traction in the broader market, beyond just NASA cargo delivery.
