10 questions linked to/from Do ("non-halo") Lissajous orbits have stable/unstable manifolds?
What is a near rectilinear halo orbit?
A proposed option for the lunar orbit of a Lunar Orbital Platform-Gateway (formerly known as Deep Space Gateway) is a near rectilinear halo orbit, or NRHO. This excellent answer discusses the ...
What asteroids have the least delta-v to reach?
I think the question needs very little clarification - specific asteroids and/or their asteroid orbit type would answer it. My own interest is in what would best suit targeting for asteroid mining on ...
The design of the halo orbit of the James Webb Space Telescope
As I feel a little less uncomfortable with "halo" orbits, with this question, I would like to explore the practical aspects, in particular those related to the design of the James Webb Space ...
What is the difference between halo orbits and Lissajous orbits?
The Wikipedia articles for halo orbit and Lissajous orbit leave me wondering how these two orbits are different from an orbital mechanical point of view. Could they be discussed together here, so I ...
How do spacecraft reach Lagrange points?
As I understand, to reach a Lagrange point the spacecraft would need to slow down. Also, can spacecraft passing nearby Lagrange points get captured within the point?
How many SpaceX 2nd stages are in heliocentric orbits?
I can think of one particularly famous SpaceX 2nd stage in heliocentric orbit that even has its own website: https://www.whereisroadster.com/ and I know one was used to send DSCOVR towards Sun-Earth ...
Low Energy Transfer within Earth-Moon system
Practical aspects of a total low energy transfer to the Moon have been seen in missions like GENESIS, which uses Weak stability Boundary legs of Earth and Sun to reach ESL-2. This four body model ...
Rendezvouses in halo or lissajous orbits
If a spacecraft was in an EM-L2 halo/lissajous orbit, and another craft would was going to approach EM-L2 a few days later, could they rendezvous immediately or is there a limitation when the second ...
Did DSCOVR travel "along the stable manifold of its future SE L1 Halo orbit" to get there?
I just wrote (and have since removed) the following paragraph in this answer to How many times do you have to circle the Earth to break orbit?: As can be heard in this video SpaceX's launch of the ...
How is it possible to connect trajectories at a Poincare section using the "bisection" method?
When constructing a heteroclinic connection (a connection between two different periodic orbits at two different libration points), the stable and unstable manifolds of two different libration points ...
