This new development looks especially interesting to me, as one of the specifications for the
"ML-1" is to place a Cubesat to LEO. This was researched, designed in the year before the
entry for N Prize.
N Prize is to be attempted with a "de-tuned", smaller version to be capable of one Pocket Cube
weighing 125 grams to LEO. This slightly smaller launcher is to use the same fabrication means,
similar parts to make use of design work done previously and to facilitate upgrade to the escape
capable ML-1.
The plans are to seek partners for both, and have the larger launcher follow the N Prize
development without a break.
The ML-1 is to have a liftoff mass of about 100-200 kg, and the "ML-N" about 1/2 to 2/3 that.
The masses will be pinned down more closely after test of the third stage engine, the
performance of which has a strong effect on the size requirement of the two lower stages.
For the MN-N, at least, beverage cans will be used for the third and maybe also the second stage.
The third stage may be 5 24 ounce cans--3 for LOX, 2 for propane or butane.
The second stage may use 5 welded pairs of 24 ounce cans, or short segments of the tubing to be
used for the first stage.
Presently planning the largest, most expensive component of the launcher design--the shop to
build/test them in: "Location One" as described in the April 2009 Space Access Society presentation
http://www.microlaunchers.com/7816/L3/sa09/sa09.html .
Preparations to locate in Henderson NV now under way. Conditions there will allow the first 3 of 4
Locations for the development.
I know it's silly to ask here, but if you know of any who might want to join the Microlauncher entry,
do contact.
