I am a bit surprised that this video does not have many more views. I found the presentation informative on the state of our current and upcoming missions which are expanding a frontier of human knowledge. These folks are our 'rock stars' of science, actually, to me, much more valuable and important than any musician, actor, or sports star. I hope the teams working on these projects realize that they are some of the most important people on our planet for our future and even our long term survival. I've never met people who exude such excitement over drill holes or self driving nails, but while I have worked with some brilliant and talented and wonderful people, I wish I had had the opportunity to work with, or just be around, more people like that as they make life much more interesting. Keep up the good work, all of you, whether on camera or not. I would buy anyone on these teams lunch or dinner in Chicago, or beverages of their choice, just to have a conversation with them about their work. These projects are awesome. Rich
Incidentally, it does not surprise me at all that a dust storm would moderate night time temperature drops. Mars is for practical purposes close to steady state over the long term temperature wise, meaning that it is giving away roughly the same amount of thermal energy as it is receiving from the sun, and actually probably a bit more from thermal energy from nuclear decay internally on the planet. Since heat can only be transferred by conduction, convection and radiation, and mars is a ball surrounded by the near vacuum of space, it can generally only give off thermal energy by radiating electromagnetic radiation, I would imagine in the far infra-red region based on its temperature ranges. Just as the dust interferes with the transmission of visible light as demonstrated by the photos in the presentation, I would expect it to have a drastic impact on the transmission of the main frequencies of light involved in the removal of energy from the planet. The impact aside from cooling the impact of sunlight on daytime would be to also moderate the night time temperature drops, similar to how water vapor as cloud cover has a similar impact on earth - frosty nights and nights with the largest temperature drops in areas on earth for example are generally nights with clear skies.
This video is all about the great use of Insight... yea right before the rover's drill got stuck in the mud. So now we don't have to go far to follow Insight. Great job guys. Whew (been stuck in the mud for 4 month.) O brother
Better late then never. I'd really like to hear the latest on InSight, last I heard it had possibly hit some rock or gravel and was in an angled position. Thanks for the video!
Dang I really wanted to ask some questions. Unfortunately I was at work during this live stream. If you're new to JPL this is some of the best space talk live streams of all time. This is the stuff you want to watch and keep up on.
I gotta suggestion or you can say a question. Why don't we just fold back up the Mickey mouse sized solar panels into a small surface area exposure , whenever we detect a wind storm is coming and then open it back up when the storm is out. In that way we don't have to worry about dust covering or any complex mechanism of wipers
@@kluandroid3095 RTGs are large, heavy, expensive, and only necessary if the vehicle has large energy demands (Curiosity) or operating too far away for solar to be an option (New Horizons). Their heat, magnetic field and radiation can interfere in some experiments. Also, we're running out of the fuel to build them, which was a byproduct of the Cold War nuclear weapons race.
if indeed nothing can be done about the dust on the solar panels because of the energy or weight requirements can't they then do something aerodynamically to the next rover so that any winds on mars are put to optimal use to clean of the solar panels by optimising airflow over them.
They thought about it extensively, Steve Squyres sometimes gets asked about it after presentations. It would add weight and complexity so they decided that the best and simplest way was to just make the solar panels as big as they could to add margin that way. Still, no one thought it would last even one year and it lasted 14.
do you want to run Mars ?, shoot with detonations? you could move more with time or, banging .. or going out. changes ecliptic trajectory. well the overheating changes the rotation mode ..and it swings .. you move .. but risk, it is not Healthy already! moves too far outside..can go out ..
Can you make a laser powered hot air balloon or drone to fly in Mars atmosphere how much radiation is in space around Mars and can it be used as a power sources?
typical, cant figure something out, just make something up, and get creds for calling it dark! lol.. jokes aside - great video, enjoyed a ton of interesting info.. thanks.
I didn't get that feeling. General questions had general answers, which is important for public talks where the audience's technical knowledge is varied. The spectroscopy question was specific. The speakers realized the answer about solar vs. nuclear should include their trade-offs even though it wasn't directly in the question.
Why not send a laser type satellite to orbit mars that COULD revive older landers and rovers or POWER new ones ,could that even been done? Or a solar panels spin in MARTIANS winds to help them clean them selves? Teach rovers to roll over ,, not die though 😍 I think a nuke power plant in space of Mars better on surfaces of it for now,, just saying,,
yeah some sort of small power plants where the rovers can fill up kinda like the automatic lawn mowers lol. The Rovers should also have a small tank of compressed air that they can shoot over the panels and after the batteries are filled just fill the compressed air again with a mini compressor...
It’s not just lack of power. Old rovers once left without power get their circuits damaged by the intense cold. Factor in age, dust and radiation in the environment and almost surely they are not just asleep but dead. This according to nasa scientists themselves.
I bet opportunity got put in the back of a truck and taken to Alien scientist on mars and jpl and nasa using opportunity to communicate with them somehow
It only took 76 days for this talk to download from JPL to us folk on planet Internet, whew.

Please release the footage of the skycrane explosion, landing on Mars:)

She's a great presenter! More stuff with her.
The first guy looked way too nervous. He's got a pretty sweet job, no need to worry about public speaking.
Great to hear about the hematite investigations.
Awesome presentation! Soo cool that Abigail got to follow the project for so long. What have I been doing with my life in the last 15 years...
God bless you guys.
There is a drone-sized helicopter on the Mars 2020 Rover. I am surprised she never mentioned it and no one brought it up in the Q&A session 😞.
Since UA-cam tending is already selected can't they put some of these on it?
Just go to Cydonia already... lots more rocks there :D

Did they not think to put a self cleaning mechanism on the solar panels?
They thought about it extensively, Steve Squyres sometimes gets asked about it after presentations. It would add weight and complexity so they decided that the best and simplest way was to just make the solar panels as big as they could to add margin that way.

@@zapfanzapfan Hey Man, thanks for the information, yeah that makes sense, I guess she had a good run! Thanks again!
Absolutely not. There design was perfect. We do nothing wrong at JPL. Wow just wow.
I cringed

Mars 2020 is going to bring a mini Helicopter to Mars as an experiment, check the Nasa websites for more info.
oy...a smurflady on steroids… :(

A bit condescending and lacking knowledge when answering audience questions.

The speakers realized the answer about solar vs. nuclear should include their trade-offs even though it wasn't directly in the question.
This entire presentation and the comments on here only have one element of condescending and it's your comment.
they seem to be answering all of them fine to me
Jack Parson was a kook

What’s holding the camera to take the selfie there’s no arm or anything
which photo are you talking about?
Corey Taylor both she called them both selfies
