Optimal depth for underground flyby?
Planetary flybys are used to modify the orbital parameters of spacecraft.
For maximum gain, a large deflection angle is often desired. But the deflection angle is limited by the closest approach, ...

How does one design a trajectory involving a lunar and Earth flyby and Lagrange points? What tools are used to calculate the initial guesses?
I'm trying to design a trajectory that takes a spacecraft from Sun-Earth L2 to a lunar flyby, to an Earth flyby and then to Mars (two flybys might be too complex, I might just do one). I've optimized ...

Patching two Lambert's problem solutions together
I am following this paper on the implementation of a genetic algorithm to find a good MGA trajectory.
The way they approach the problem is by solving the Lambert problem for each planetary transfer. ...

Why are all trajectories in space a conic sections?
All trajectories available in space: circle, ellipse, parabola, hyperbola, straight line are parts of cone. Why? Does the spacetime have a conic shape?

Patched conics Earth to Mars transfer, find Vinf at arrival at Mars
I've tried to solve a patched conic problem found on the 8th chapter of Fundamentals of Astrodynamics, Bate, Mueller and White, Dover 1971. Attached is the problem, which concerns the sub part (e), ...

Design of return trajectory from lunar polar orbit to Earth's atmosphere
Given a flight path angle, altitude and velocity at re-entry into the Earth's atmosphere, how do I go about designing the return trajectory from a polar orbit at 17km altitude about the lunar surface ...

Patched conic approximation targeting retrograde LLO yields prograde orbit
I'm playing around with optimization of a patched conic approximation for a transit from earth orbit to LLO, and when I take the resulting retrograde trajectory and plug it into an integrator, I get a ...

How to best patch my conics?
I thought I'd try to use patched conics to see what it's like. I'll go from LEO to LXO (low Planet-X orbit), co-planar all the way.
If I understand correctly, I'll have (at least) five conics. The ...
