I can’t remember the exact time, but I know that they have to do all the instructions in one go and send them together. It’s the same with all the rovers due to the time delay.

I've got Software that allows me to preplan my drone's route prior to it taking off by using way points. I'm guessing the first flight will be basically just up and down to get a look at the terrain and then use that information to plan further flights. All guesswork on my part of course.

I would guess that as well. They have satellites in orbit that they might use to look at the terrain.

very interesting, thanks for this info

This is a great video: How will the universe end? Based upon the best science we have today (which could change of course) it covers the trillions of years in the future when all matter in the universe will disappear. Does it leave you feeling depressed or, conversely, does it put put your own problems into true perspective? I find more the latter actually.

You can watch NASA's Mars Rover landing tonight live on YouTube.

Perseverance. That’s a clear Leith/Hibs reference.
Another first for Leith, First Robot To Mars

I can’t wait to watch it. The 7 minutes of terror must be absolutely torturous for the people who have put years of work into this program. I remember watching the Curiosity landing, the people in mission control looked ill with worry during that 7 minutes. I’m sure they’re using the same landing technique this time, so that might ease their nerves a little.

Around 15 minutes until we enter the martian atmosphere, genuinely nervous!

Same here.

Almost a decade of planning, design and execution all boils down to the next 10 minutes. I cannot imagine the stress and worry that team must be feeling right now.

Entry has begun, they must be bricking it right now.

Incredible scenes in control, that was epic and it looks like everything went absolutely perfectly. Amazing.

Touchdown on Mars. Get in there.

[Jay]

Really emotional. Amazing stuff. My boys name is on Mars!

Are the photos actually B and W, or are the lenses covered in dust?

I'd imagine there will be a lot of dust kicked up by the landing, but those cameras are the engineering cameras for navigation which as far as I'm aware, were "on" for the landing and aren't as high-res as the cameras which we will be seeing images from over the coming weeks.

Engineering camera will be B/W - low bandwidth, easy enough to send a quick black and white pic to show it's landed.

[CropleyWasGod]

Cheers both. I was starting to wonder if there was a budget issue 😁

Both. All the cameras on the rover are black and white. Any images you see from space are taken in black and white and then the colour is added when they’re released. I might be wrong but I think there might be a colour camera on the Juno probe orbiting Jupiter.

Great explanation of why that’s the case here:

Has the wee helicopter got a video camera on it? That would be cool, some drone footage..

Thanks. I’d seen something like that before, but that went into much more detail. Like I said earlier I think Juno has a colour camera, but it’s purely used for public interest, the rest of the cameras are black and white and used for research.

Yes, it has 2 colour cameras.

NASA JPL has confirmed that the Rotorcraft that Perseverance took to Mars, Ingenuity has successfully performed the first powered flight by a human craft on another Planet



EDIT: Footage from the Rover of the flight of Ingenuity
