I'm headed down to SC for a beer festival myself so if it goes Friday I'll miss it.

NASA has issued the attached notice to mariners activating the Wallops danger area for the hotfire test on Feb. 22, 4-9 pm.  Notes the water & marsh area between the island and the mainland will also be closed.

Makes it kinda official, right?

We can expect an FAA issued NOTAM for the 7K Test in next 48 Hours.

Clearly this will be making a lot more ground-level smoke than a launch - is there a preferred wind direction for the test?

Sorry to put all your hopes up - I double checked, and it appears that the F9 hotfire has been moved away from the 22nd. Well at least that means one less distraction to this hotfire!  :-[

F9 source please... Also do we have a time for Orbital's hotfire on the 22nd.

The L2 updates threads. No time stated for Orbital's hotfire there though.

It was on the programmable LED sign when I drove through the gate at Wallops this morning. THAT makes it official...  ;D

Also, speaking to the wind direction, I heard that there is a wind direction and magnitude limit but I'm not sure what they are. I do believe it has to do with all the smoke / steam that will be generated.


edit: And 6 pm - 9 pm was the time stated on the sign. Too bad I'm not going to be in town!

a possible nighttime test, should be a good show for locals.

I'd expect seeing the smoke and vapor cloud in daylight would be more impressive than what little light is expected to be seen from under the engines.

Antares Engine Test Scheduled for Feb. 2202.20.13

WALLOPS ISLAND, Va. – NASA's Wallops Flight Facility will provide launch range support for an Orbital Sciences Corp. Antares rocket engine test scheduled for Feb. 22 at the Mid-Atlantic Regional Spaceport's Pad-0A.

The window for the engine test, or hot fire, is 6- 9 p.m. EST.

The test will fire the Antares' dual AJ26 rocket engines, which will generate a combined total thrust of 680,000 lbs., for about 30 seconds while the first stage of the test rocket will be held down on the pad. The hot fire will demonstrate the readiness of the rocket's first stage and launch pad fueling systems to support upcoming flights.

The test will be visible and audible in the Wallops Island local area. Given the broad window and non-operational nature of the test, no live webcast or formal public viewing is planned. NASA's Wallops Flight Facility will provide range support for the hot fire, including communications, data collection, range safety and area clearance.

The test is a key milestone leading up to the first flight of the Antares rocket, which is preliminary scheduled for about four to six weeks following the completion of the engine test.

Orbital is building and testing its new rocket and Cygnus cargo spacecraft under NASA's Commercial Orbital Transportation Services (COTS) program. NASA initiatives like COTS are helping develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the International Space Station and low-Earth orbit.

A demonstration flight of Antares and Cygnus to the space station is planned for later this year. Following the successful completion of the COTS demonstration mission to the station, Orbital will begin regular cargo resupply flights to the orbiting laboratory through NASA's Commercial Resupply Services contract.

The launch pad is the first of its kind constructed in the United States in decades. Preparations at the pad for the hot fire test were enabled through partnership between the Spaceport, Orbital and NASA, including representatives from Wallops; NASA's Stennis Space Center in Bay St. Louis, Miss.; NASA's Kennedy Space Center in Florida; NASA's Marshall Space Flight Center in Hunstville, Ala.; and NASA's Johnson Space Center in Houston.

Has the purge seals popped yet, liquids started to flow down there, things ignited and violent thrust ensued?

Will it still go with light rain?
