### LEO Satellite Service / Coverage Time Calculation for a Ground User

I want to determine the time interval during which a ground user is in the coverage of a particular LEO satellite. I only have knowledge of the user's geographical location and the satellite's TLE (...

### How long would it take to travel from the moon to the asteroid belt/Jupiter with fusion powered space travel?

I am writing a science fiction story that involves fusion powered space travel, but not constant acceleration like in the Expanse. Instead, the manned spacecraft accelerates at the beginning of the ...

### Could time illusion be used to send a spacecraft faster than the speed of light?

In this article (https://www.nasa.gov/feature/goddard/2022/hubble-spots-ultra-speedy-jet-blasting-from-star-crash) it says: The Hubble measurement showed the jet was moving at an apparent velocity ...

### Calculating the time of flight between two anomalies gives a negative result?

I want to calculate the time of flight (TOF) between two true anomalies on an orbit with known orbital elements. Based on this wikipedia article and the post Time of flight between two anomalies in a ...

### Efficiency in Space Capsule Docking Process

I'm watching the first operational Crew Dragon Capsule proceed through the regimented, and VERY careful International Space Station (ISS) docking process, which was turned on after pausing another ...

### Range of travel time between particular planets using the Interplanetary Transport Network/Interplanetary Superhighway?

I understand the Interplanetary Transport Network allows for travel at low speeds between different planets in the solar system using very little energy. Is there flexibility in how long it would take ...

### Does Kepler's Method for Determining Time of flight between two True Anomalies break down with eccentricities approaching 1?

Pretty simple question here. I'm calculating time of flight between two true anomalies by converting those true anomalies to mean anomalies and using the following equation: \$\Delta t = t_2-t_1 = \...

### Could a chemically propelled craft travel directly between Earth and Mars spaceports?

If in the near future we manage to build out some infrastructure in space--including robotic asteroid mining so that we can get water without pushing it up a gravity well--are LOX/LH2 rockets powerful ...

### With current or near-future projectable technology, how long would it take a ship to fly from Earth to a theoretical Earth-Sun L4 or L5 space station

Lets assume there's a space station already built, so this would be a flight off earth, brief acceleration, coasting most of the way, brief deceleration and connect with the station. I'm assuming ...

### How can I find the time of flight between spheres of influence?

I'm simulating an interplanetary trajectory between two spheres of influence. I have already simulated a hyperbolic escape within the sphere of influence and have arrived at the boundary of the ...

### Time of flight between two anomalies in a known orbital trajectory

Suppose I know all of the orbital elements of a particular orbital trajectory (not necessarily an elliptical one). Suppose I know the position and true anomalies at two different points in this ...
