PSAS/ news/ 1999-10-20 - General Meeting in PCAT 103

In attendance : Glenn L., Todd R., Paul G., Brian O., Matt R., Anthony P., Jamey S., Marty C., Matt M., Tim B., Andrew G.
Absent : Ron S., Jim W., Roger J., Bart M., Steve D., Michael K.

* During Tuesdays meeting two main topics were discussed. The first being, "where do we go from here". Though this has been loosely talked about before we did not reach a group consensus till this evening. An overall vision statement was decided upon and then we started on the functional decomposition of how we would get there. A lot of time was spent on general specifications for our next launch vehicle LV-2.
The second topic of discussion was rescheduling the launch of LV1b and what it will take to get ready. More specifically, what we want to get completed on the avionics package (above basic functionality) that would make us happy, and also have the assurance that we are gaining some significant knowledge that we can then apply to LV2.
A breakdown of the components still needing work or testing was made and responsibility assigned to members of the group. It was decided to wait until the work was completed on the LV1b avionics before we applied for a new FAA waiver and set a firm date for the launch.
It was a good meeting and we got a lot of details ironed out along with sharpening our future focus. The meeting next Wednesday will be for those members working on the LV1b avionics.

Long term vision statement:

Work towards creating a small, inexpensive reusable launch system with the ability to put nanosatellites into orbit.

Big steps to get there:

Create an actively guided, recoverable, small, and inexpensive sub-orbital launch vehicle.


Use cheap, off the shelf technologies where possible for reproducibility.

Next Step for getting there: Launch Vehicle No.2
