UPDATE 5:10 a.m., June 2, 2017: The launch from NASA's Wallops Flight Facility of a Terrier-Improved Malemute sounding rocket testing a new deployment system to support space science studies scheduled for June 2 has been rescheduled for June 3. The launch window is 4:26 – 4:41 a.m. EDT. The launch has been rescheduled because of cloudy skies this morning at both ground camera stations – Wallops and Duck, N.C. Clear skies are required at one of the ground sits to view blue-green and red artificial clouds that will be produced as part the test. These artificial clouds may be seen from New York to North Carolina.

UPDATE (5 a.m., June 4): NASA Postpones Sounding Rocket Launch from Wallops

The launch of a Terrier-Improved Malemute sounding rocket scheduled for June 4 from NASA's Wallops Flight Facility has been postponed due to clouds impacting the ability to test a new ampoule ejection system designed to support studies of the ionosphere and aurora.

While the launch window runs through June 6, forecast weather is not conducive for supporting the test mission through the remainder of the window. The launch is now scheduled for no earlier than June 11, pending range availability.

NASA has two ground stations—at Wallops and Duck, N.C.—to view blue-green and red artificial clouds that will be produced as part of the test. Clear skies are required at one of the two ground stations for this test.

The June 4 attempt was the fourth for this mission. The first two attempts were scrubbed due to winds and clouds. The third attempt was scrubbed due to boats in the launch hazard area.

The multi-canister ampoule ejection system flying on this mission will allow scientists to gather information over a much larger area than previously able.

Canisters will deploy between 4 and 5.5 minutes after launch releasing blue-green and red vapor to form artificial clouds. These clouds, or vapor tracers, allow scientists on the ground to visually track particle motions in space. The clouds may be visible along the mid-Atlantic coastline from New York to North Carolina.

More information on the new date and time will be released when available; updates will be posted to www.nasa.gov/wallops.

Update (June 11): NASA Postpones Sounding Rocket Launch from Wallops

The launch of a Terrier-Improved Malemute sounding rocket scheduled for June 11 from NASA's Wallops Flight Facility has been postponed due to boats in the launch range hazard area impacting the ability to test a new ampoule ejection system for supporting studies of the ionosphere and aurora.

The launch has been rescheduled for Monday, June 12, with a launch window from 9:04 to 9:19 p.m. EDT.

This was the fifth launch attempt for this mission. Previous attempts have scrubbed for various reasons: high winds, clouds in the area leading to poor science conditions, and boats in the hazard area.

Wallops launch of sounding rocket to provide light show
June 12, 2017 by Chris Bergin



A Terrier-Improved Malemute sounding rocket is set to provide people on the mid-Atlantic coast with a luminescent cloud light show on Monday night. The sounding rocket – set for launch from Wallops Flight Research Facility – will help NASA test a new system that supports science studies of the ionosphere and aurora.
 
Sounding Rocket Launch:

Спойлер

The launch has been delayed a few times, first due to unacceptable weather and the most recent – on Sunday night – due to a boat in the range.

The Terrier-Malemute launch vehicle is a high-performance two-stage vehicle used for payloads weighing less than 400 pounds.



The first stage booster consists of a Terrier MK 12 Mod 1 rocket motor with four 340 square inch fin panels arranged in a cruciform configuration. The Terrier booster has an overall diameter of 18 inches.

For a payload weight of 200 pounds, the longitudinal acceleration during the boost phase is 26g's. The second stage propulsion unit is a Thiokol Malemute TU-758 rocket motor which is designed especially for high altitude research rocket applications. The external diameter of the Malemute is 16 inches.

The average thrust is 9,604 pounds. The maximum thrust level is approximately 14,200 pounds which results in a maximum longitudinal acceleration during second stage burning of 32g's for a 200 pound payload.

Liftoff weight of the Terrier-Malemute launch vehicle, less payload, is approximately 3260 pounds. This vehicle is usually rail launched and can be accommodated at most established launch ranges.

...



During the flight of a two-stage Terrier-Improved Malemute sounding rocket, 10 canisters about the size of a soft drink can will be deployed in the air, 6 to 12 miles away from the 670-pound main payload.

The canisters will deploy between 4 and 5.5 minutes after launch forming blue-green and red artificial clouds. These clouds, or vapor tracers, allow scientists on the ground to visually track particle motions in space.

The development of the multi-canister ampoule ejection system will allow scientists to gather information over a much larger area than previously allowed when deploying the tracers just from the main payload.

Ground cameras will be stationed at Wallops and in Duck, North Carolina, to view the vapor tracers.

Clear skies are required at one of the two ground stations for this test.



The vapor tracers are formed through the interaction of barium, strontium and cupric-oxide. The tracers will be released at altitudes 96 to 124 miles high and pose no hazard to residents along the mid-Atlantic coast.

The blue-green and red vapor tracers may be visible from New York to North Carolina and westward to Charlottesville, Virginia. These clouds, or vapor tracers, allow scientists on the ground to visually track particle motions in space.

The total flight time for the mission is expected to be about 8 minutes. The payload will land in the Atlantic Ocean about 90 miles from Wallops Island and will not be recovered.

Range is green for boats. Well done @WaywardBoat - keep it that way.
