Planetary flybys are used to modify the orbital parameters of spacecraft.
For maximum gain, a large deflection angle is often desired. But the deflection angle is limited by the closest approach, ...

I found myself wondering about what ever had happened to the Mariner 2 spacecraft (the first successful flyby of any planet) after it flew by planet Venus.
According to apesinspace.co it "...

Most meteor showers are yearly events. In the manga "SoSo no Frieren" the characters experience a meteor shower that happens only once every fifty years. The story does not take place on ...

Again, I did some research, and again, the results aren't that impressive.
I was able to find that SLS is to become the " successor to the retired Space Shuttle, and the primary launch vehicle of ...

NASA has already made images of planets from the solar system
before. So why is NASA/ESA making images of planets from the solar system
by using the JWST instead of exploring unseen parts of universe?...

Nitrogen trifluoride (NF3) is a liquid between 66K and 144K and has an incredible density of 1.885 g/cm2. It has a pretty great specific impulse, although combustion temp is a bit high, and AFAIK is ...

The Artemis H2 leak has been quoted in %. I believe 4% is the stated limit. I assume that measurement is vol % of H2 in air but I haven't seen any real definition of the parameter. What is the ...

As follows from the mission timeline:
Launch - August 5, 2011
Deep Space Maneuvers - August/September 2012
Earth flyby gravity assist - October 2013
Jupiter arrival - July 2016
Spacecraft will orbit ...

I understand there in no air is space which is what allows an aircraft to fly a curved flight path. This is strictly a theoretical question given today's technology. Here are the conditions:
There ...

Incidentally I don't mean "on the lunar surface, asleep laying on the surface of the moon" :)
So (A) who (if anyone) was the first human to actually be asleep (that is to say, presumably inside the ...

If you have the energy for a constant 1G thrust, how long would it take to get to the planets in our solar system? How long for the 5 nearest solar systems?
Assuming turn over and decelerate at ...

I'm a noob in this subject and know little about space exploration, but I wonder about this every time I read the news:
Wouldn't drag make all space junk fall back to Earth after some time?
I'm ...

I assume there is some reason we don't use magnets to launch off Earth.
Are they not strong enough? Isn't magnetic force technically stronger than gravity??
Would either of these work:
A tube tunnel ...

This may be a vague question, please let me know if more info is needed.
As we know, NASA put a man on the moon using technologies that we no longer use, like slide rules and entire teams of people ...

Can you answer these questions?

I want to determine the rotation matrix from which compute the Euler Angles to rotate my spacecraft in order to point in a specific direction. For example, i want the z body axis of the spacecraft to ...

Is there any place aside from NASA-JPL web page, where there is only some general information about the missions, where one can find more in-depth detailed values?
For instance, I am looking for the ...

I would like to run in some simulation software an end-to-end simulation replicating the flight of voyager 1. I am somewhat conversant with GMAT that I think would have this capability or perhaps ...
