LCLV Various independently-funded launch vehicles have been advocated, designed, and even developed over the years. A lot of these are attempts to build low-cost launch vehicles using simpler technology. Often such projects begin based on a low cost liquid fuel technology but end up just trying to sell various combinations of Castor solid fuel stages. These enterprises often discover there's more to coming up with a reliable launch vehicle than slashing together a bunch of 'off the shelf' rocket motors and lighting the fuse.... On the other hand, if there is ever a breakthrough in less expensive access to space, it will come through one of these entrepreneurial schemes... More...

Associated Launch Sites
Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...

: Noise in guidance system led to excessive steering of one of the booster motors and finally depletion of the motor's hydraulic fluid. The vehicle went out of control at T+46 seconds.. Failed Stage
- Meteor - .
Nation: USA. Agency: EER. Apogee: 10 km (6 mi). At T+44.4 seconds the vehicle started a turn to the south and pitched down. The ISDS destruct system commanded the destruct packages at T+46.202 seconds. The ISDS failed to operate on two Castor 4 stage 1 motors but operated on the other four. At T+47.67 sec the ISDS destroyed a non-burning Castor 4B motor. The third stage Castor 4B and fourth stage Star 48 were not destroyed and impacted in the ocean. Cause of the failure was identified as the flight control system attempting to respond to noise being received on a data line, resulting in early depletion of hydraulic control steering fluid on stage 1 motor 6.
