Summary:
Trojan-2010TK7 which is one of the four Trojans (Asteroids that has same orbit as of earth around the sun) was discovered in 2010. It was formed along with other planets in our solar system and interesting part is it is located at Lagrangian point(L-5). A fly-by/Landing mission to this Trojan would reveal many answers of early solar system. Goal of the project was to design a Fly-by mission from Earth Parking Orbit (EPO) to Trojan-2010Tk7 which is presently located at Lagrange point(L5).
My contribution to project was:
1) Optimized Trajectory Design from EPO to Trojan for minimum Delta-V budget.Classical orbit determination-Lambert method was used for trajectory design
2) Re-entry Dynamics of Reentry Module: 3-DOF equations used for Dynamics of Reentry Module.
MATLAB code was written in to achieve the above objectives .
Some Results:
Optimized Trajectory results:
Orbit of Trojan 2010TK7 obtained from NASA JPL NEAR EARTH OBJECT(SMALL BODY) DATABASE
Orbit of Trojan 2010TK7 obtained from NASA JPL NEAR EARTH OBJECT(SMALL BODY) DATABASE
Validation of MATLAB code through delta-v values from Mangalyan (Mars) Mission.
