I have been checking in detail the specifications of RINEX navigation files version 3.05, and something in the definition of the header of these navigation files caught my attention.
One of the lines ...

I was watching this video essay discussion about space elevators, and on a bit of a tangent, the physicist talks about difficulties with interstellar missions, specifically comments about navigation ...

While trying to find details on the proposed improved Space Shuttle heat shields, I stumbled across a fact I'd forgotten: the orbiters didn't have navigation lights (i.e. red left, green right, white ...

I am suspecting that it is easier to detect a satellite because in the space, there is no other thing. In other words, the background is cleaner.
Is it right?

I am trying to program slew maneuver procedure for a spacecraft. My goal is to define a target coordinate system that is aligned with sun vector so that the spacecraft can slew its attitude to always ...

I am wondering if there is any international organization regulating such things.
Possibly countries do not need to tell anything about their spy satellites, but should tell about their commercial ...

What is the highest number of satellites that have been launched on a single rocket? What were the number of stages used in that launch?
(It may be from the past or a future mission)

As a student of economics and finance I would love to learn more about the cost structures of sending a payload into orbit.
More specifically -
What is the cost-per-pound to send something into LEO ...

Well I'm new to Space SE and have gone through many questions but I couldn't help but notice that is it even remotely possible
that one can touch the stars without burning him/her self ? Is there any ...

I'm trying to write an orbital simulation with patched conics. For my sources I'm using https://orbital-mechanics.space/ and Fundamentals of Astrodynamics (Second Edition).
Both sources suggest to use ...

Suppose a three body scenario with an artificial satellite, a planet (much massive than the satellite), and a sun (much massive than the planet). There is no other significant force on these three ...

Diffractive lightsails use small gratings embedded in thin films to produce diffraction (which causes light to spread out when it passes through a narrow opening).
Diffractive light sails are a ...
