Mars helicopter completes first test flight


Week Four: Ninth Anniversary Fund-Raising Drive for Behind the Black
 

The fourth week of my annual anniversary fund-raising campaign for Behind the Black has begun.


I once again must thank the many readers and listeners who have generously donated this month. Right now there is a chance this will be the best fund-raiser ever, though only if a lot of people donate during the month's last ten days. If you want to help me continue my reporting, you can give a one-time contribution, from $5 to $100, or a regular subscription for as little as $2 per month.


For one time donations via Paypal, click here:

The small helicopter that will fly autonomously as part of the Mars 2020 rover mission has successfully completed its first test flights here on Earth.

“We only required a 2-inch (5-centimeter) hover to obtain all the data sets needed to confirm that our Mars helicopter flies autonomously as designed in a thin Mars-like atmosphere; there was no need to go higher. It was a heck of a first flight,” [said Teddy Tzanetos, test conductor for the Mars Helicopter at JPL.]

The Mars Helicopter’s first flight was followed up by a second in the vacuum chamber the following day. Logging a grand total of one minute of flight time at an altitude of 2 inches (5 centimeters), more than 1,500 individual pieces of carbon fiber, flight-grade aluminum, silicon, copper, foil and foam have proven that they can work together as a cohesive unit.

This helicopter drone is a technology experiment, more focused on testing helicopter flying on Mars that doing science. If it proves to work, it will open up a whole new unmanned option for exploring the Martian surface. Imagine a helicopter that takes short hops from point to point. It will be able to reach locations a rover never could, and do it faster.

    Rotors attached to a rover could be used to clean solar cells!

    I’ve always envisioned sweepers or dusters of some sort, but if there is enough atmosphere the be propelled by rotors, they could be used to clean surfaces too.

    If there’s enough atmosphere to support a helicopter, then there must be enough to transmit sound. Should be trivial to include a microphone so we can hear the “sounds of Mars”

    I got out my grandson’s toy helicopter. The lithium ion battery won’t hold a charge anymore, so I went to the hobby shop. They had one that would work but was slightly too large for a different model. It was only five bucks so I installed it thinking it will stay in the air longer but what actually happened is it could only rise a couple of inches… That’s it. The air from the rotors has a downdraft that will lift it up, when it has the floor to push against.
    If the craft with 10,000 RPM blades cannot lift itself more than a few inches in a six millibars of pressure (near vacuum) then it is not gonna work. (Except for removing dust)
