MESTLER Mission Details

The "ANDRover" is a Bluetooth enabled remote rover that will be controlled by the Galaxy Nexus via 4G LTE. "Mission Control" will control the rover over LTE via a remote Chromebook.

The launch vehicle name "Mestler" is inspired after my 5th grade science teacher "Mr. Mestler". He was an incredible teacher, made science fun and exciting, and was a positive contributor to my education, career path and interest in science and space exploration. 
Vehicle names are typically tied to something or someone of relative importance in science, exploration, education, etc. so I thought this was appropriate.

He was of American Indian heritage and proud of it. Where he could, he incorporated his heritage into his teaching method, and it was inspiring even as a young student.  
Instead of grading students using the traditional A-F, he used a symbolic sun for grading. The rays of the sun were indicative of the grade we received IE: All four rays was an "A", only the two center rays meant a "B", and so on.

So I felt it was only fitting that I somehow included that symbol into the final logo for the "MESTLER" lander.

MESTLER / ANDRover MissionA high power rocket ("MESTLER") designed to carry a lander and a remote controlled rover ("ANDRover") to (+/-) 2500'.

The mission goals: Deploy and land a fully autonomous lander containing a rover. Upon successful landing 
deploy and control the ANDRover remotely via an Galaxy Nexus (GNEX): PC uplink to GNEX via LTE, GNEX uplink to ANDRover via Bluetooth. Click here for General Specifications

MESTLER Launch Failure Videos

Launch Date: July 23rd, 2016 at NARAM58

These two videos show the catastrophic launch failure from two perspectives. The forward motor casing appears to have failed which resulted in a 100% loss of all vehicles.

MESTLER Build Videos

These two videos demonstrate how the pyro events occur on both the rocket and the lander.

Pyro events on the rocket are required to release the payload bay doors (which releases the lander).

Pyro events on the lander are required to:

(1) Release tethers allowing the lander legs to deploy.

(2) Release the main descent chute after touchdown (to avoid dragging the lander after touchdown).

These two videos demonstrate the rovers mobility and its functionality.

The rover is Bluetooth enabled and paired to a Samsung Galaxy Nexus (located in the MESTLER Lander) providing remote control capabilities.

The rover itself is powered by a digiStump Digispark micro controller.

It is constructed with Lego parts and 360 degree modified servo motors.
