From NASA's Wallops Flight Facility facebook...
The launch of the two sounding rockets supporting the Daytime Dynamo experiment from the Wallops Flight Facility has been postponed to no earlier than Sunday, June 30. The postponement is because of unacceptable weather forecasted for Saturday, June 29. A decision on whether to launch on June 30 will be made tomorrow evening. The launch window remains 9:30 – 11:30 a.m.

Heard on a local radio station this AM that the launch is scrubbed for today (it is quite clouding this morning), next attempt NET Tuesday.
From WFF facebook:
"The launch this morning of the 2 rockets for the Daytime Dynamo experiment has been scrubbed because of weather. We will take a look at Tuesday, July 2, sfter this afternoon's weather briefing."

Sounds like a swing and a miss for GBI
According to http://www.missiledefenseadvocacy.org/news.aspx?news_id=4772 the GBI record is now, "Eight intercepts out of 14 intercept attempts."
Ouch.
That statistic isn't granular enough. How many of those failures were GBI itself? How many payload? Non-vehicle ground? Target? Guidance? System-level?
Need more information.

You know
, shudder, wiki has a complete list:
http://en.wikipedia.org/wiki/Ground-Based_Midcourse_DefenseI am curious where the 14 half of the statistic comes from.
By my wiki math 17 intercept attempts and with 8 hits and 20 additional non intercept flight tests with 2 failures and one mixed results.
Of the 9 intercept failures
2 failures to launch
2 failures to separate
1 cooling failure
1 misbehaving target
1 ground radar failure
and
2 misses
The disturbing thing about these tests, is it is only the second 4000 mile test (and second failure). The distance from Iran and North Korea ranges from 6000 to 8000 miles depending on what you target. Vehicles flying that profile have not yet been targeted. We do not know how it will perform against targets that will be flying faster and higher than what has been intercepted to date.
No statistics actually exist for an ICBM launched from Iran or North Korea because no test against ICBM's profiles have actually been flown.

There have only been 12 "Taurus Lite" based launches. None of those launch vehicles have failed. Some of the "failures" listed above may have included tests that did not see an interceptor launched at all.
The main problem with this system is that it has been neglected by, well, whoever is in charge. There were no tests at all for two full years - for a system that obviously needs to be pushed much harder in testing.
OBV has flown an average of once per year since the first launch in 2003. They should be flying these once per month, in my opinion.

Ed, I'm sure the reason for the low flight rate is political.
More concerning to me, is it will be several years before it fly's against a representative
ICBM flight profile. Until those tests occur, the whole systems ability to intercept anything lobbed at the US from Iran, North Korea, China, Russia, or France should be prefaced with a giant question mark. And we know the French are just itching to push ze button
It's a system that may work against ICBM's, but the two tests against targets with a 4000 mile failed.

Here is some insight into the recent GBI failure. The interceptor apparently did not separate from the third stage, possible due to a "faulty battery".
http://news.yahoo.com/pentagon-wants-more-regular-testing-failed-missile-test-193545623.html
I wonder if this was an interceptor battery or a launch vehicle battery.
- Ed Kyle
Another failure to separate? This would be the fourth failure to separate! Wow!
But, to be fair, it was the first failure to separate, when the OBV booster was used.
The earlier separation failures were 2 times on the PLV test booster and one time on Lockheed Martin's BV-Plus booster.

The Brazilian rocket VS-30 was launched from Esrange Space Center on July 15, at 0553UTC. It reached an altitude of approx. 151 kilometers and landed 60 km north of Esrange Space Center. Recovery has been made and the payload is back at the base for analysis. MAPHEUS 4 is a DLR research rocket programme conducting annual launches of scientific payloads dedicated to material studies. Experiments on MAPHEUS cover a wide range of material physics topics such as gelation, the behaviour of granulates, diffusion and the mixing and demixing of metallic alloys. Propelled by a S30 motor, MAPHEUS typically offers more than three minutes of microgravity time at 10-4g.
