Thank you, however I am still confused.
The International Space Station orbits around 400 km above the Earth's surface. According to Wikipedia this would put the ISS in the Thermosphere, which extends from 85 KM to 500-1,000 KM above Earth atmosphere.
Again according to Wikipedia...
Hello,
Can someone please explain to me how Astronauts in Low Earth Orbit do not instantly fry up when in direct sunlight?
How does the International Space station, for example, not become a torch-lit super-oven when the sun's rays hit its walls?
Thank you for helping me understand, and...
M(rocket) x V(rocket) = M(Fuel) x V(fuel)
I am assuming we are using meters, Kg, and Newtons?
Let me recalculate the recoil involved in firing an M16:
Weight of M16 = 4Kg; Weight of M16 bullet = 0.004Kg; speed of M16 bullet = 950m/s
4Kg x V(M16 rifle) = 0.004Kg x 950m/s
So using this...
According to Wikipedia: "the megajoule (MJ) is equal to one million joules, or approximately the kinetic energy of a one-ton vehicle moving at 160 km/h (100 mph)."

How can an 760,000Kg Ariane 5 rocket lift off its own weight and free itself from...
Hi Chestermiller,
In what way is the conversion from Joules to Horsepower incorrect? In what way are the units wrong? Could you please clarify any errors I have made? Thank you.
You are right! The outflow of an Ariane rocket is 2,000Kg PER booster. Since the French fusée has two EAP (Étages...
Hello forum members and thank you for letting me post.
My question refers to how rocket thrust works in a vacuum. I know this question has been posted before, but I am still confused about how it works.
My understanding is that rockets do not move by pushing against air but move by pushing...
Thank you Travis_King!
Mass of craft = 3,600 kg x 0.38 (gravity on Mars) = 1368 (Kg?)
Mars acceleration due to gravity = 3.71 m/s²
8 thrusters 800 lbf of thrust each / two thrusters per frame / four frames total
The craft is diving at 125 m / s at 1620 m altitude and slows down to 20 m /s...
Anyone?
Is there not one person who can help me calculate the forces involved?
I am not sure how to calculate this, please help...
Vehicle mass is 3,600 Kg.
Vehicle is falling at speed 125m/s at altitude 1620 m.
Mars pull of gravity is 3.71 m/s²...
Hello AlephZero,
Thank you for your reply. I am not suggesting anything. I am fascinated by the MSL mission and in particular the powered descent stage. I want to understand how it functions and when I looked at the joints connecting the thrusters with the main body I asked myself how they...
Thank you for anwering Aero51.
My question does not relate to what happened, but what would happen considering the mechanics involved.
With all the parameters and considering the width and size of the frames holding the thrusters, are they what an engineer would build to withstand the weight...
Hello and thank you for allowing me to post a question.
I am not very familiar with systems engineering and have a question about the frame joints connecting the main body of the MSL (Mars Science Laboratory) powered descent stage with its 8 Aerojet MR-80B 800 lbs thrusters (1).
I am...
