The Mars Helicopter aims to make the first powered flight on another planet when it takes off on Mars as part of the Mars 2020 mission. I learned a lot getting to visit the drone right before it was mounted on the rover.

How do you fly in 1% of Earth's atmosphere:
Have large rotors (they are 1.2m in diameter) and spin them very fast, around 2500 RPM (5x the speed of a helicopter on Earth).

Plus the aircraft has to be light:
The Mars helicopter weighs in at 1.8kg or around the same as a laptop. Every piece had to be stripped down for weight. Instead of using aerogel for insulation, the craft makes use of CO2 gaps between components. Even aerogel was too heavy!

One of the major challenges is surviving the Martian night:
Temperatures plunge to -80C to -100C so two thirds of the craft's power is actually used to keep its electronics warm. Only one third is used for flying. The estimated flight time is 90 seconds.

The craft can't be driven remotely, it will have to fly autonomously, using its own sensor suite to determine how to fly. The round trip 20 minute delay with Earth means steering the craft from mission control would be impossible.

They let this guy go everywhere. He should ask to go to Area 51. He will be our inside man.

The Wright's first flight was 12 seconds. We're starting on another planet at 90 seconds.

Where will we be in 20 years?

How to tell if a video will be interesting: "I'm at the Jet Propulsion Laboratory..."

The most important question: How long until we can fly it over Opportunity to blow the dust off her solar panels and revive her?

It's mind boggling to think about everything that must go right for this mission to be a success.

5:43 Sounds like a lawnmower to me. A very expensive mars lawn mower to annoy mars neighbours.

Aerigon: Let's make the most expensive drone at $250 000



...



Nasa: Hold my space balls..
$23 million for 90 sec flight time.





... I know technically its not a drone but with all the sensors and whatnot it may as well be.

Could this be used for clearing the dead rover's solar panels

When you have to compare to the metric system with coins, laptops and who knows what else....
