Competition
The Base 11 Space Challenge is a $1 million+ prize for a student-led university team to design, build, and launch a liquid-propelled, single-stage rocket to an altitude of 100 km (the Karman Line) by December 30, 2021. [...] The biggest purse, which is fully funded, is the $1 million prize for launching the rocket to the edge of space.

Vehicle Overview

Tangerine Space Machine is MASA's spaceshot rocket, designed to fly to the edge of space at hypersonic speeds. It has an all-aluminum exterior, with welded propellant tanks that act as the aerostructure. The 3,500 lbf engine is fueled by liquid oxygen (LOx) and refined kerosene (RP-1) using a helium pressure-fed system. It is passively controlled with trapezoidal fins and has a conical nose cone. The fill-system plumbing on the launch pad uses four fluid mother-tanks to load the propellants, including an avionics station with radio communication. The mission control system uses radio communication with the pad and has a trailer for personnel to perform remote launch procedures.

Flight Dynamics
Tangerine Space Machine is continually evaluated with state-of-the-art flight dynamics software. Analysis consists of everything from commercial Computational Fluid Dynamics (CFD) programs to evaluate individual components, to overall flight simulations, custom-built by MASA. With these tools, we can design the vehicle and its aerodynamic surfaces to achieve the highest and safest flight. TSM is 25 feet long with a conical nosecone and 4 trapezoidal fins.
Propulsion
Tangerine Space Machine will be powered by a Kero/LOx pressure fed engine. The engine will have a thrust around 3500 pounds. This refined kerosene/liquid oxygen engine is designed to bring the rocket to its apogee of 400,000ft. The Kero/LOx engine, as yet unnamed, will be a regeneratively cooled engine made almost entirely in-house which uses a like-doublet injector element. Our current-generation PT-163 LOx/EtOH engine serves as a testbed for many of the technologies critical to TSM's Kero/LOx engine.
Aerostructures
Tangerine Space Machine's airframe is made up of a series of rolled, welded aluminum tubes which house the various sections of the rocket. The propellant tanks are also welded and rolled aluminum and act as airframe in their sections of the rocket, with critical plumbing and wire harnesses in those sections being routed through a raceway along the outside of the rocket. The nose cone will be rolled and welded aluminum with a titanium tip.
Avionics & Telemetry
The TSM engine controller is a student designed-and-built PCB with runs on custom firmware. It controls engine solenoids & valves, the ignitor, and reads data from thermocouples, pressure transducers, level sensors, etc. The flight computer contains the live telemetry system that relays live data from flight sensors to radio stations on the ground and via Iridium satlink. The flight computer also includes the recovery electronics that read data from redundant flight sensors and controls recovery actions such as parachute deployment.
Recovery
Recovering a rocket from space is not a trivial task, and MASA aims to accomplish this with safety in mind, without sacrificing performance. MASA has designed a novel separation mechanism for TSM which will allow for a drogue parachute to be deployed at apogee, while another event triggers deployment of a much larger main parachute closer to the ground, bringing the vehicle to a safe landing on the desert floor.
