Speed of rotation of stars in rim around center of milky way: 53 Km / sec

Develop a partial differential equation for this, calculate and show this graphically as a function of distance from center at three points

Propose a vehicle with point of launch on planet earth (assume 39B, KSC, Florida (for x, y co-ordinates)), show reverse calculations from one of points in rim to point of launch (orbit selection) (use planetary drag coefficients), its design, calculate stresses (structural, thermal, fluid and vibration), mode of construction and launch (vertical or horizontal) and propose its material of construction.

Develop a construction (manufacturing and operation) plan fpr most suitable optimized launch window (Nov – Dec).

Propose direct or indirect (low earth orbit (7.1 Km / sec)) lauch to final orbit (~ 53.1 Km / sec), discuss its merits and demerits, propose fuel, its type and calculate its amount for round trip (Consider all possibilities (Chemical, nuclear, electric and plasma propulsion))
