The question of how many impulses are necessary to optimize a transfer-type maneuver has
remained open for decades. Recently, the introduction of optimal switching surfaces …

Impulsive trajectories provide time-and Δ V-reachability insights. Two novel homotopy-
based methods are proposed for generating optimal many-impulse, multirevolution …

A method is proposed to generate an initial guess for impulsive trajectory design in the
circular restricted three-body problem. The method uses acceleration-based switching …

Under the two-body dynamics assumptions, we have proven that given a sufficiently long
flight time, generating infinitely many extremal impulsive solutions is possible without …

Rendezvous maneuvers are designed to match the position and velocity vectors of a target
body (eg, planet, comet, satellite) whereas transfer maneuvers are designed to match the …

The question of how many impulses is necessary to optimize a transfer-type maneuver has
remained open for decades. Recently, the introduction of optimal switching surfaces …

We study the multiplicity of minimum-∆ v impulsive trajectories for long-time-horizon
problems. One notable feature of these extremal impulsive trajectories is that many of the …
