Very nice. Recently saw this offered on an online auction site and was curious about it. Happy with the details in this video. One question though... it looks like the Sun is also spinning, which if it is, is a nice feature. I zoomed in, but I was not sure if the movement I noticed was just because of the zoom effect or possibly caused by planets moving around it causing some shadows that gave impression of movement of the Sun orb.

I am an agriculture student Your explanation made easy to know about difference

I just got the kit to make my own, I'm so excited.

Thanks for the vid! I'm building my own orrery and this was super helpful! I'm glad you enjoyed it so much!

I hope you reply! How did you calculate the error to adjust the orrery?

So exciting! :D Thanks for this update!

What do you think of Lindsay's book series?

Thank you I learned a lot

What a stupid way of presenting information. Folding laundry? Seriously? You didn't answer anything conclusively. Dude, the Curiosity Rover had an extremely short mission duration because of the anticipated dust issues. Selfies taken, showed the panels covered in dust. And then, all-of-a-sudden, we see that the panels have been cleaned and the mission extended $ $ $ How did they clean those panels Mr. Laundry Man?

Or how about allowing the solar panels to rotate on the axis of their arms so that they face downward, say at night or during a dust storm, so as to minimize the amount of time they are facing upward and dust can land on them?

I don't recall which probe it was that included the drone helicopter. But in that case, would it be possible to hover the drone helicopter over the solar panels, since you're flying it anyway, and use its downblast to blow the dust away?

love ya

My nuking Jupiter plan failed!

big karma now

leather man!

I have loved these since seeing Aughra's orrery in The Dark Crystal 💖

That was super-cool. Thanks for sharing this.

Excellent explanation! Thank you!

This is fantastic content! The details about how it was tested, I've never heard about that descbribed before. *chef kiss* Good stuff.

As always, your enthusiasm is contagious! And here‘s my question, even though I know it isn‘t exactly your field: how does one find and maneuver to the Lagrange parking spots? I guess there are no lines drawn on the ground…

Great educational video!

You could do what Scott Manley is doing and talk about what's going on in space for the week. Perhaps provide some info that others can't due to your knowledge / background. Like I asked you once why insight didn't just have a broom to remove dust from it's solar panels and you gave a very good answer. You could for example have a video about why JWST doesn't have cameras.

Kudos on the new gig! One question: Is there any appetite for a planetary or solar system-scoped logistics mission to support future missions? Like maybe a Mars Positioning System to guide navigation in the future.

Whoa this big bad-assed biker dude! He sounds familiar! Congratulations on your new job!

So excite! Looking forward to more 💖

Really glad you're enjoying the new role, but bummer that you can't talk about the missions, but I understand the reasoning behind that. Quick question for you: InSight's robotic arm was placed on the ground during December and has been there since. Speculation on the forums includes 'soils science' or a 'noise reduction' exercise to reduce noise from the wind passing over the arm shaking the lander, as noise from the lander could be swamping the smaller Marsquake signals from being read by SEIS. Do you have any insight (pardon the pun) on the actual reason? If not, would you care to speculate what you think it could be? We'll get the answer in the PDS, but that will be towards the end of the year. TIA and keep up the good work

That's amazing, congratulations! Sounds like the most fun! 😁

love when the woke eat the woke.

Yay! Welcome back!

Just subscribed and am loving having more LGBTQ+ content creators in these circles. It breaks my heart to know Lindsay Ellis has to resort to this in order to heal, but seeing a video like this is inspiration for us who want to put our foot down against intolerable behavior and create content.

That's how good you were! obviously people want to talk to you! So happy you are back!!!!!!!!!!!

Damn I saw the goodbye tweet but I thought she was just quitting Twitter and I was like good I'm proud you're getting out. She was my favorite creator 🥺

Thanks for coming back to YT, and a belated „Happy Birthday“ from my side of the pond! While the cause is sad, it is great to be hearing more from you in the future. Also, I wish you all the success in the world (and beyond this planet) in developing new and exciting missions that help inspire humanity as well as individuals. It’s the answers that science gives that make us ask more and newer questions. And curiosity is the fuel for our dreams. Never let yourself be daunted by ignorance, fear and blind hatred.

Glad to see you back. I appreciate your talking about how insight affected you. Emotions are not something a lot of engineers ever discuss. That takes some courage to do.

I'm so grateful for your presence and content and your thoughtful words. And your beautiful baritone voice.

Whatever you decide to post at whatever schedule, I’m here for it.

If you like “Contrapoints”, then you will probably also like “Philosophy tube”.

I would prefer the spelling "rhegolith"; rhegolith< ῥηγόλιθος< ῥῆγος (blanket) + λίθος (rock). The added H letter is the spīritus asper from the original Greek word. (Other similar examples: Rhodes, rhythm, rhetorical, rhinorrhagy, haemorrhage, otorhinolaryngology, etc.) Thank you for sharing.

Thanks for answering this question. It still confuses me why a wiper arm didn't make it. Even if it only works a few times wouldn't that prolong the mission greatly? Wouldn't even have to clean the whole panel just a small section. But like you said static clings and if you say it's not an effective option I'll take your word for it lol

I would love to use lunar and/or martian regolith in a composite material. How expensive would it be to get some lunar regolith shipped down here?

thank you for this!

No it would SMELL LIKE rotten eggs because of H2S gas! we didnt ask about what the effect would be!

Why is your latest post not allowing comments? You deserve nothing but my deepest congratulations and respect. The whole process you guys went through was AMAZING. The beauty in art comes from an artists struggle with his limited medium. You tried to do the hardest thing humans have ever done and it was inspiring to watch.

I am very sorry to hear the news about HP3. I know you and the rest of the team gave it everything that you had to give. I wish you the best of luck on future projects.

I heard the panels have been mysteriously cleaned 5 times or so. I believed it..

Short answer: nothing Long answer: bloody nothing

Ick.

I am considering researching a large drill (viz. digging out tunnels) Mars operation for my masters thesis. As you say, it will need more power than has been used in missions so far. In this case, active cleaning methods need to be investigated. I actually found your video while doing some provisional background research. Subscribed.
