The team received their first status report from the helicopter on Friday.

By Julia Musto | Fox News

NASA's first-ever Mars helicopter is preparing to take to the Martian skies following Thursday's successful Perseverance rover landing in the planet's Jezero Crater.

Ingenuity is currently attached to the rover's belly and its mission is also historic: the 4-pound helicopter will attempt the first powered-controlled flight on another planet.


However, in order to successfully do so, Perseverance will have to take additional steps to prepare before it can embark on the hunt for a safe takeoff site.

Over the next month or two, engineers will test the rover's systems and instruments before the flight test phase can begin.



NASA announced Friday that they had received their first status report from the helicopter, indicating it is operating as expected.

On Saturday, the team will move to power up its six lithium-ion batteries to about 30% of its total capacity and incrementally increase charge from the rover's power supply on a weekly basis.

After Perseverance releases Ingenuity onto the surface, the helicopter will be charged solely by its own solar panel.


Ingenuity has a month-long window for up to five test flights, but it won't be an easy process.

Mars has nights with temperatures as cold as minus 130 degrees Fahrenheit and the planet has a rarefied atmosphere that's just about 1% of the density of Earth's atmosphere -- though the planet's gravity could give the helicopter a boost.

Once Perseverance locates a site to deploy Ingenuity, the rover’s Mars Helicopter Delivery System will shed the landing cover and gently drop it.

"Percy" will also help NASA communicate with Ingenuity -- which will make a lot of its own decisions because of interplanetary communication delays -- using programmed parameters set by engineers.

For example, Ingenuity has a thermostat to help it keep warm, as well as the ability to analyze and sensor data and images of the planet's terrain, like Perseverance's Terrain Relative Navigation.

According to NASA, a victorious maiden takeoff and hover would meet 90% of the team's project goals.


"We are in uncharted territory, but this team is used to that," said Jet Propulsion Laboratory Ingenuity Project Manager MiMi Aung. "Just about every milestone from here through the end of our flight demonstration program will be a first, and each has to succeed for us to go on to the next. We’ll enjoy this good news for the moment, but then we have to get back to work."

Them NASA boys must be smarter than me.
I can’t figure how they’ll fly that contraption when it takes 12 minutes for a radio signal to get there.
And 1% of earths atmosphere??   That thing will really need some serious RPMs to get off the ground.

Mars must have sufficient atmosphere to support a drone...I wonder what type of gas it is ?

It’s battery powered.

Don't know what the atmosphere consists of, but if it is only 1% as dense as ours, I just don't see how that thing could generate enough lift to fly.

Yeah, a low barometric pressure can affect the max takeoff weight of an airplane by thousands of pounds.

Very high RPM and two rotors on one shaft. Atmosphere is mostly carbon dioxide.

But if it's only 1% of Earth's atmosphere, that is almost a vacuum.

The atmosphere of Mars is the layer of gases surrounding Mars. It is primarily composed of carbon dioxide, molecular nitrogen and argon. It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen and other noble gases. The atmosphere of Mars is much thinner than Earth's. Wikipedia
Average surface pressure: 610 Pa (0.088 psi)
Oxygen: 0.174%
Carbon dioxide: 95.32%
Carbon monoxide: 0.0747%
Water vapor: 0.03% (variable)
Mass: 2.5 1016 kg
Nitrogen: 2.6%

Still better than Venus. Which the Chinese are planning to send a probe to.

5 to 20 minutes depending on planet positions, accourding to NASA.

I think he was referring to the atmosphere. Since there has been some questions about that.

Let’s say that the chopper is cruising along and a big rock looms up ahead.  The choppers takes a b/w picture and transmits it to earth where it arrives 12 minutes later.
NASA cranks one way on their joystick and 12 minutes later that command reaches the chopper which by now is probably a crumpled pile of sheet metal at the base of that big rock.
24 minutes have elapsed.
Now it may have all kinds of failsafes built in but that’s a long way off to troubleshoot if something goes wrong.
Remember, when seconds count, NASA is minutes away. :)

Onboard hazard directional radar. NASA had already planned for any of those scenarios. For one thing, it would have to know to gain altitude, or change direction to avoid such a collision. Simple, AI drone technology. Which we've had for some time now.

OH come on,  ;D  I would expect such a  lack of knowledge from today's yout's  >:(  ; it is 90 some percent Carbon Dioxide with a small percentage of Nitrogen and Oxygen plus at least one other. 8)

That was been common knowledge when I was still in Junior High, IG you went to school back when they actually taught lessons to educate, not indoctrinate.
That is why the living on Mars BS, and the  dreamland way scientist say they are going to increase the oxygen content so we can live on Mars is such asinine true science fiction to me.  :o

   I guess I should have worded that better...and used the term "atmosphere" twice... ;D

Bob, it's called terraforming, a term that first showed up in Science Fiction. We in no way yet have the understanding or the ability to do that. But it's still tossed around a lot. What ever we end up doing or hope to,
will still involve the use of HABS. The cavern idea was a good one, but not in this century.

   My son as a professional photographer and FAA licensed drone pilot, uses drones regularly in his work.  He has several models and uses them according to the application.  Hid drones are far more sensitive than the usual hobbyist drone, but of course, not likely anywhere near what NASA has.

  Still, his drones have  and on board radar system of some kind, built to avoid objects.. Still, laast summer I was helping him film a developing trail system within NY State.  Much of this was being built through woods and over abandoned railroad beds.  I drove an ATV, while he sat beside, piloting the drone.
  He still had to guide the drone very carefully, since it would avoid trees very well, but sometimes the smallest twig would throw it into a skid, which may drive it into another, tree, opposite of the first one.

  He does many commercials and infomercials.  Recently he was flying through a manufacturing shop, when his drone passed between two transformers..located both sides of his path...it was a "sticky~wicket for a while.

  Here is a short infomercial he made for a local firm.  It demonstrates how drones can be used to illustrate a process/product.  This firm produces some of the best welding machine positioners in the world...and some oif the largest..

We are jumping the gun on all of this. Just like we are with AI and the Androids. Sure we can make a robot, but a robot is all it is. Sure Sophia is advanced, but if you watch her she is still scripted in her responses.

You did ok IG, with all the talk about atmosphere. It was easy to know what you meant.
