Powered Flight from Earth to Mars - Find Help Here

AI Thread Summary
The discussion centers on the complexities of powered flight from Earth to Mars, particularly how orbits differ from unpowered flight. Users emphasize that powered trajectories require numerical methods for calculation, as traditional conic sections do not apply. The conversation highlights various propulsion methods, including ion drives and chemical rockets, and the implications of continuous thrust on flight dynamics. Participants express interest in both constant acceleration scenarios and multistage powered flight options. The need for specific trajectory calculations in powered interplanetary travel is a key focus.

lemme start of by saying hi...

i came across this forum on a search in google and found it nice...

i got a nice problem that i cud use help on

we all know the ususal orbital mechanics of the conic sections. this type of orbit occurs only in unpowered flight (where u don't use any engines, just use the gravity field of planets)

what wud the orbits be like if the flight was powered.

im looking at interplanetary powered flight say from Earth to mars.

anyone has already done this or know how todo this... help!

thx

Hi revenant, welcome to PF!

AFAIK it needs to be done numerically.

There is probably something out there somewhere. Look up trajectories relating to 'ion drives' which are continuously powered spacecraft .
 
Are you interested in a trickle accelleration, like from an ion engine, or a quick flight where you're accelerating at 1g for half your flight, and decelerating at 1g for the second half?
 
well... the type of engine is chemical rocket/electrical/ion... that is i can use them all or just one of them or any two of them... its basically multistage and its powered flight. so u have thrust coming in the force equation and its no longer conic, angular momentum is also not conserved!
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
