There is a new mission in the mix. The spread spectrum telemetry system on Away 26 performed well enough to show that we’re heading in the right direction, but, not well enough to for the demands of the roller deployed balloon mission. The original Away 27 mission has been bumped to Away 28. The new Away 27 mission will carry the upgraded spread spectrum telemetry system and qualify it for more complex flights.

Away 27 will be a small vehicle, under five pounds. In addition to the telemetry system, there will be PongSats and at least one digital camera on board.

We expect to fly Away 27 mid summer.

Away 28 is a technology development mission for the Dark Sky Station (DSS). The last DSS we flew used round rubber balloons like those on Away 26. The next DSS will use plastic balloons like those used on Away 25. Having ten tall balloons all streaming high above the station has many problems, not the least of which is tangling. To avoid all this flapping around the balloons will be kept on rollers. During takeoff the balloons will only be a small bubble of helium held low on the frame. As the balloon expands during the climb the roller will unroll more balloon material.

Away 28 will test a single roller deployment system. This technology will help open the way for the extremely large Dark Sky Stations to come.

New ML Rocket

This fall we will start deploying Mach Gliders from the MicroSat Launcher (ML) rocket, (see the balloon deployment
video on the video page). Time to build another rocket! Last Saturday we pulled put the airframe mandrel and the molds. Some minor repairs need to be done on the carbon ovens an and the jigs and we’ll be ready start building.

Some of the MLs carbon fiber parts fresh out of the molds. (ML #3).

This rocket will be the last of the Block 4 vehicles before moving to the larger Block 5 ML.
