How interesting. News and traffic reports from Mars Chopper 1 on the local news?
Freeways on Mars.
Works for me.
The rotors must be huge to get any lift in that thin atmosphere.

bkmk
it does look like they are large in ratio to a light load.
Wikipedia has an article about the Mars Helicopter.
The whole vehicle weighs about 4lbs. A pair of of contra-rotating blades with a diameter of just over 36in spinning 1,900-2,800 rpm. It’s solar powered and each flight is meant to last no more than 3 minutes each. It only carries cameras. Supposedly, it’s being carried beneath the rover. It’ll drop the copter off, drive away, and then the copter will deploy it’s rotors and lift off.
I thought as you did, thinking the blades would look more like paddles. But it looks like they’re looking at rotational speed to create the necessary lift in the thin atmosphere.
Yeah, you and Lurkin are right: those are big blades for the payload.
not bad for a psych major LOL
I can see it now: The Sheila Jackson Lee Interstate.
“The Sheila Jackson Lee Interstate.”
It’ll be a speed trap.

with incorrect hwy signs
Can we send her up for the Grand Opening?
Return trip? Oh, we haven’t quite worked out how to do that yet; you just sit tight, Ms Lee, sit tight.
*ping*
Is Mars on lockdown?
“The whole vehicle weighs about 4lbs”
Thinner atmosphere, but 4 pounds on Mars is.....is anybody here George Costanza?
[Thinner atmosphere]
That’s what I was thinking too. Would explain the design.
What is tungsten, or Wolfram?
100 pounds on Earth is 38 pounds on Mars.
So 25 of these would weigh 38 pounds.
So one would weigh....
I’m still stuck.
Calculate the velocity, V, in relation to the trajectory, T, in which G, gravity, of course, remains a constant.
This piece of lettuce represents how much of George’s brain was previously used.
Now granted...
