Mc. Coy School of Engineering Midwestern State University A FUTURE GOLD RUSH: CAPTURING ASTEROIDS WADE COURTNEY & TYLER THOMAS MENTOR: DR. M. SALIM AZZOUZ FRIDAY JULY 5 TH 2013 UGROW RESEARCH PROGRAM
OBJECTIVE & MOTIVATION Objective: Developing an elaborate concept of capturing an asteroid passing nearby earth, landing it safely on earth and exploiting its raw materials. Motivation: v v v v Asteroids are worth trillions of dollars PMG can be used to reduce the deficit and paying debts Elements can be used in high tech manufacturing processes Elements can be used to build efficient solar power satellites in outer space Assist in alleviating an asteroid threat Can be used for military purposes Cleaning debris in outer space Gold Platinum
LOGISTICS FOR CAPTURING AN ASTEROID v v v v Launching System Space Stations Detection and Cataloging Approaching an Asteroid Capturing an Asteroid Processing Re-entry of Asteroids Capturing an Asteroid Approaching an
LAUNCHING SYSTEMS EXISTING SYSTEMS v v Non-reusable Losing millions of $$ v Non Modular v Dead Weight v FUTURE CONCEPT v Reusable v Modular v Active Weight v Uses Inflatable Heat Shields No Inflatable Heat Shield Modular Re-Usable Rocket Concept
SPACE STATION v v Orbital Space Stations can be positioned at LEO, MEO, GEO, & lunar orbit Functions includes: § § § v Preparation for Rocket Re-entry Storage of Fuel, Food, Materials, Spacecraft etc. Repairing or upgrading existing satellites Processing Asteroids Living Quarters for Astronauts Structure includes many docking Space Station
DETECTION & CATALOG v v v Lasers will be used to sweep a wide area in Earth’s proximity to detect both small and large size asteroids Every asteroid detected will be cataloged and its composition determined The system must be capable of detecting a threatening asteroids months and years in advance
DETECTION, CATALOGING, & COMPOSITION Iron Cobalt v 1 LD = 238, 900 miles v 1 km/s = 2, 237 mph http: //neo. jpl. nasa. gov/ca/ Iridiu
APPROACHING AN ASTEROID v v v Determine the orbit of approach of the capturing spacecraft by a navigation team Determine the speed of the asteroid and match the speed of the spacecraft for approach Spacecraft must be equipped with fuel tanks to supply sufficient fuel for the round trip
LOGISTICS CAPTURING AN ASTEROID v v Spacecraft is equipped with RS-25 engine because of their reusable reputation Spacecraft has ion engine as alternate engine v Two fuel reservoirs for the RS-25 v RS-25 engine has 400, 000 lbf thrust v Solar Panels Fuel Reservoirs RS-25 Fixing the asteroid with drill bits, magnets, gravity attraction, or bag-net Robotic Capture Arms Directional Thrusters
PROCESSING ASTEROIDS v v Processing of asteroids will occur at the Lunar orbit Space station infrastructure will include an asteroid processing plant Asteroids will be prepared for re-entry at the lunar orbit Build a manufacture plant to separate the different elements of the asteroid v GEO space station infrastructure will include fuel station for asteroid capturing spacecraft
RE-ENTRY OF ASTEROIDS v Asteroids will be fixed and restrained in a chamber in the module v Thermal Protection Systems will be fixed onto the module v Parachutes will be fixed to the module for landing v Recovery and Emergency Crews will prepare on earth soil for recovery Captured Asteroid Inflatable Heat Shield Rocket Module Asteroid Restraints and Foam Sketch of An Asteroid Re-entry
CONCLUSION v v v We established a business model for capturing asteroids We proposed a model for reusable modular rocket system Fuel is at the heart of making this enterprise successful We proposed a model to match the speed of the asteroid We can land an asteroid on earth safely
