How to calculate a delta-v to match orbital planes from two state vectors
I’m working on a 3D program, and I'm trying to get two independent satellites to match orbital planes (at least close enough for a 3D visual).
I cannot get anything to work. Here’s the problem:
Given ...

Calculation of a rendezvous from an elliptical orbit to another [duplicate]
I am familiar with computing rendezvous maneuvers using a Hohmann transfer when the two orbits are circular. However, when both orbits are highly elliptical, the fairly simple calculations with a ...

It is possible to perform a simplified version of rpo with GMAT?
I have one target vehicle and a chaser. How can I perform an orbit transfer with GMAT but, at the end of the transfer this finished maintaining a relative position of 1000 m behind the target and 1000 ...

Moving target during rendezvous
I am currently studying rendezvous and docking. I noticed the elliptic Hill equations only consider the acceleration of the target satellite due to its elliptic orbit (and fictitious forces in LVLH ...

Two different Hill's equations for space rendezvous
I have stumbled upon two variations of Hill’s equations across numerous scientific journals:
$\newcommand\w{\omega}\newcommand\m[1]{\begin{bmatrix}#1\end{bmatrix}}$
$$\m{\dot{x} \\ \dot{y} \\ \dot{z} ...

Understanding the Viewgraph by Dr. John Houbolt and the probability of success calculation of a Lunar Landing
The well known Dr. John Houbolt used a viewgraph to explain the much higher probability of success with LOR in comparison to EOR and Direct Flight for a lunar landing.
I used Python to check the ...

Who first conceptualized the space rendezvous?
For the Apollo mission, there was a debate on which mode is better - the Earth orbit rendezvous (EOR) or the lunar orbit rendezvous (LOR). Who was the first person to introduce the concept of space ...

Could astronauts jump from a spaceship onto a spacestation and how would it be like if yes?
I saw it happen in the videogame Alien:Isolation but not sure how realistic it was. I need help understanding some orbital mechanics for a sci-fi story that I am trying to write.
The scenario I ...

How will DART be able to hit a 170 meter rock dead-center at over 6000 m/s? What technologies will be use and how will they work together?
The DART spacecraft will ultimately be a kinetic energy impactor, using its 500 kg mass at a relative velocity of over 6000 m/s to slightly change its target 65803 Didymos's companion Dimorphos's ...

How to correctly change velocity in space?
The solver of the Lambert's problem gives me a hyperbolic velocity to move to some position on orbit. But the spacecraft is moving on orbit and changing the velocity takes some time. So, when I ...
