"This is a design concept named Mesquito (purposely spelled wrong). This is a single stage sounding rocket and will launch at 120G acceleration. The motor will burns for two seconds then separates from the payload, called the dart (only 4" diameter, very small). The dart will reach a maximum altitude of 80-100Km, roughly 50-62 miles in the air.
This particular launch was a test rocket launched from NASA's Wallops Flight Facility on Wallops Island in Virginia. It has no TM and is tracked by both WFF's tracking radars and the Navy's AEGIS Ballistics Missile Defense System due to the extreme speed and acceleration of this rocket. Note that the rocket breaks the sound barrier only a few feet from leaving the rail." Wiki
I was recently "informed" on The Rocketry Planet that boosted darts do not work best with high thrust motors. That was a bit before getting banned for "not believing what others tell me" or something along those lines. In any event, here is more about this rocket:
"Mesospheric Sounding Rocket Development (Mesquito)12.065 and 12.066 test flights were launched from Wallops Island on May 6 and May 7, respectively. Wallops Flight Facility radars and Navy SPY radars were used to provide performance data. WFF radars tracked the booster motor for the 12.065 flight (left). The Navy radar did not acquire. The WFF radar obtained data at about T+3 seconds for the 12.066 flight. The bore site camera shows an unstable booster after burnout. The video also indicates the booster did not have fins during the descent. The vehicle accelerated at 120 G’s and reached Mach 4.8 in 3.2 seconds." Wallops
