Rescue quadcopter

Hi Bruce

Discussion on rescue quadcopter

Please advise what is required for the Mars flight of a quad copter

1. Mars less mass than earth
2. Atmosphere thinner

Please tell us if an earth based quadcopter will fly on mars

or will it need larger props

but less weight may result in longer flying times

or shorter flying times

this is the question.

Hi Rod

Some feedback from me.

Are you referring to data -
The atmospheric pressure on Mars is less than 1 percent that of Earth, and the Martian gravity field is about three-eighths as strong as it is on Earth
https://spaceflightnow.com/2018/03/15/n ... 020-rover/

1) If they need controlled directional flight this is cool, however a balloon with small directional fan/thrusters could circumnavigate the planet many times.(Yes big ballon)

2) induction charging means that the rover could re-power the drone quickly.

So is this a case of if you have a hammer, everything looks like a nail?

Hi Rod

This 2017 Balloon on Mars paper, contains lots of useful environmental data, including altitude, wind speeds, etc. - https://preserve.lehigh.edu/cgi/viewcon ... ontext=etd
