The California State University Long Beach Beach Launch Team recently launched their Beach 1 liquid fuelled rocket on January 5th. Beach 1, fueled with liquid methane and liquid oxygen reach an estimated apogee of 6000 ft (1828 m) but unfortunately sustained critical damage upon landing. This particular rocket will be retired as the team now sets their focus on the FAR Mars Prize (set for March 2-3, 2019) and the Base 11 Space Challenge.

Video Caption: WARNING: I was told it’s loud so turn down the volume. Two state rocket more tests at the FAR site on January 5, 2019. First test was a 100 mm seven grain 7615 N-sec KNSB motor with a new lightweight forward bulkhead welded into the motor case with a new titanium nozzle machined by Sugar Shot to Space member Chris Coveny.
The motor failed when the bulkhead gave way resulting in the motor thrusting down into the concrete test stand foundation. That caused the nozzle to be forced up into the aluminum motor case that mushroomed as a result of the impact.
The nozzle was cut from the motor case and used a second time in a six grain 6,900 N-second previously launched flight motor with conventional bolted in bulkhead. This second successful test showed no erosion of the nozzle throat. The nozzle was also cool to the touch soon after firing, something not possible with a steel or graphite nozzle.

FAR is the Friends of Amateur Rocketry and is an organisation and test facility in the Mojave Desert where experimenters can test and launch their rocket projects.

Sugar Shot 2 Space (SS2S) are working towards a space shot of an entirely sugar propellant fueled rocket.
Video Caption: Small scale 2-stage Sugar Shot flight for testing our avionics and recovery. Booster performed well and recovered with no damage. The second stage failed to ignite (problem was found and will be corrected. Second stage recovery also successful with no damage. 150 mm ‘O’ impulse motor was successfully launched last June.
75mm second stage was successfully flown several times both as a single stage and as the second stage on a 100 mm booster.
Bugger sums this up!
