If they are the best of the best, why don't they come up with the idea that any two-year-old would come up with, to make the solar panels rotate 180° so that the dust just falls down?
Thank you for this video. I appreciate your storytelling skills. Unlike some science channels that just throw facts at viewers, you weave a compelling narrative relating human goals and ideals along with the data.
I like how Alex humanizes the rovers, it reminds me that there are real people, huge teams of them, that care a lot about these robots, Mars and what mysteries it still holds, I know I do.
I always ask my kids, how many people worked on this product before we purchased it. Once one kid got a job at walmart,, she says: You are right, Grandma, people do make and move all these products!
The Mole just goes to show how easy it is to get hyper focused on certain details and completely disregard so many other possibilities which may hinder its intended progression. It kind of reminds me of SpaceX trying to land SN-XX and failing until someone said, "How about we try all three rockets to land it and if one doesn't work, we'll still have the other two available rockets to land the thing." They spent so much time on trying to get just two rockets to work that they completely overlooked the obvious solution of trying all three and cutting one off if indeed they all fired. Lo and behold, the thing worked. Gold star for the stupid guy in the back.
The voice, the narrative, the level of scientific accuracy, the journalistic integrity, your ability to captivate emotionally and intellectually 11/10 🔥
Outstanding video! As an armchair planetary astrophysicist and enthusiast, I applaud this educational effort. The geology and potential paleontology of Mars is fascinating. I'm looking forward to what we will learn in the coming decades. I hope I'm around to see it all.
I really appreciate hearing the details of the equipment and operational challenges! First it shows us, as engineers, the range of circumstances and variability we need to at least try to accommodate for in our designs. Second, it's a compelling human story. Thank you!
Always a joy to watch your videos. This channel is one of the most educational and informative channels on YT. Thank you for sharing all the knowledge!
As with your other videos, this has very high educational value which your excellent script together which great narrative skill makes them quit astounding.

@@alphagt62 Aye it is. It's why I'm happy for them to take their time with Mars compared to the Moon. Some people still want people on Mars by 2026 and they probably wouldn't survive two days.
Have to justify all that cost somehow. BTW, if vast amounts of minerals are found on Mars, guess who reaps the rewards? Private corporations. In other words, billions of taxpayers dollars will be spent to find the ore in the first place, then private corporations will step in to profit. In the very least 50% of the profits should go back to the government once production is ongoing.
One of the more interesting discovers was when when on 24 December 2021, InSight registered vibrations equivalent to a magnitude 4.0 marsquake. Satellite images of a 150-meter-wide crater later confirmed that a meteor had struck thousands of kilometers away from the lander. This particular shock excited seismologists because unlike previously recorded impacts, it was strong enough to produce surface waves.

@@ultramindcontrolrealzz8367 wym do 'nothing'? nasa, along with most government funded space agencies around the world, have achieved some absolutely incredible things.
Ideas to help remove dust... Something like a CA Duster that would move in a circular pattern around the panels every so often? Or be able to tilt the panels so they are vertical (maybe not even that much) and then a small vibratory motor to shake the panels and help the remove the dust. One other thought, a small compressor (if that's possible to compress Martian Air) that can send compressed air through small openings scattered around each panel.
There are a hundred ways to improve Insight's design. Given that weight and volume are a big factor, I was thinking of a compressed air cylinder with hoses and small diffusers pointing at each panel. It would only be a few grams, and something the size of a pellet gun cartridge would keep them clear for years. Use argon for extra mass. The gas would be so dense compared to Martian atmo that it would blast the dust away. Run the bot until it's on its last legs, then release a puff and go right back to work.
Fold/unfold the panels again to get the dust off, fire those rocket thrusters to shake the lander... Surely they would've found a way if they wanted the mission to continue and had more of their budget to spend on extending it.
@BB Sky The air pressures is also a lot lower so there's less molecules thwt can move. I think that means a 35 wind on Mars would feel a lot less stronger. The opening scene in The Martian could not happen on Mars, as far as the amount of dust, particles, and wind strength. If this is not correct please let me know.
Not only are these video's satisfying my thirst for knowledge about these subjects, it also puts the incredible work of these people, which would often go unseen by the vast majority, on display. They deserve to be as famous as rock stars for what they are able to achieve for mankind. WE HAVE PICTURES FROM THE SURFACE OF OTHER PLANETS! That is just mind blowing to me. Thank you Astrum, and thank you to all the many fine people that endeavour to progress humanity to the stars.
It's a shame that the solar panels were not equipped with a cleaning mechanism. I envisage a long thin brush possibly pivoting in the centre of each panel array and could revolve to wipe over all panels. Maybe the brush head could rotate also to increase effectiveness. But I guess hindsight is a wonderful thing.
You would think, but I've asked a lot of people and the message is *it's harder than it looks!* A wiper is just sandpaper with extra steps. People don't realize how different it is with basically no atmosphere and absolutely no water. You can't compress air to use, because frankly, there isn't enough and it's full of dust too. Worse, this dust is WAY finer than anything you're likely to find on earth... Water makes things clump up, but there simply isn't any on Mars. Dust can be as arbitrarily small as you like. To learn more, learn about Lunar Dust. The final boss of dust management! It's a genuinely impossible engineering challenge, we've tried many times and many ways. You see the siesmometer had a wiper, but only until it was placed against the ground. So it's only meant to work once or twice, and did not need to be optically clear. Managing dust in space in general is a nightmare. The electricity and mass both attract dust in space. Imagine a world where wiping dust out wouldn't send it away, but just above the surface only to inevitably drift back.
Fantastic homage to an insightful mission. I hope the Phoenix lander platform can be improved with dust mitigation, since I have no doubt it could have outlived even Perseverance and perhaps be joined by additional seismic sensing landers.
Issue is missions often come with limited lifespan requirements, this time 2 years only. Anything over is a bonus. If your mitigation system requires mass, it takes away space for other instruments, or increases cost. Oppy going for 15 years is great, but not planned/designed for.
Brilliantly written script and once again so well narrated with your lucid voice! You have a real gift for teaching and condensing a lot of scientific data to be understandable for one with just my lay perspective. THANKS!
Isn’t it amazing? We live in a time where we get to see photos of the surface of Mars, a clear, high resolution picture of Pluto, we are going to see another mission to the moon very soon, we are studying the moons of the gas giants, we get to see incredible pictures thanks to JWST… Truly blessed!
Do you mean Artemis 2? I've hard it won't be until 2025 now, which I think is really sad. I was hoping it would be next year or 2024. But I haven't had time to double check that.
And yeah, it's exciting. Next year is going to be such a big year for space missions too. In fact the next 3 are. Huge years. And we're lucky to see it.

I figured I'd be skimming one 50-minute video about rocks on Mars. (Rocks...for 50 minutes...really? Yes, really!) Three videos watched straight through and almost two hours later, I've just subscribed. Very well presented and compelling content. The "humanizing" of these scientific instruments complimented in other comments really isn't over-done, either.
@@cyberwop well i slightly disagree. We definitely have introduced single celled organisms like bacteria to Mars when we introduced robots. Mars probably hides single celled life too. Everything is possible.
I used to work as a fence builder. In New England, instead of digging, we used pneumatic air hammers to pound steel pipes into the ground for our posts. Dirt is unpredictable. One rock can throw you off. It was a two man job, with one man on the trigger and another just keeping the post straight. But the most important factor was gravity - the more your hammer weighed, the better it would drive that steel into the ground. I wish the NASA techs could have known this before attempting to bring a hammer to Mars light enough for a space craft!
the “machines” humans are creating are absolutely incredible. i love find out about our sister planets. when i was a kid in the ‘50’s, Mars still had canals. (read Ray Bradbury’s Mars Chronicles. they’re quite dated, but Martians are fascinating.) :) ☄️
@feralblues, In Solaris, an intelligent planet conjures up and materializes memories of humans. I feel that Bradbury's Mars - or its indigenous life forms, the 'dark and golden eyed' - works in the same psychological way. Bradbury's Chronicles are poetic and have a rural American feel; a "sitting on porches in the evening and drinking dandelion wine" kind of atrmosphere. The rockets that bring the colonists from Earth are never described in detail, It's like the Earth people even imagined their space ships. Same with the oxygen and autumnal weather conditions. Ray was at least so subtle to not call Mars "Barsoom"...
I followed this whole mission via Twitter so this was great to read it all stitched together with far more depth thank you very much for this awesome video
I love your videos. I was really into astronomy as a child. Today, my expertise is cartography and earth science, but I love listening to your videos while I work.
To me this has all told me Terraforming Mars would be far easier than expected as it might be as easy as breaking the surface crust up and getting it moving again at which point the atmosphere will thicken, water will start to be released in mass quantities as much is under ground and locked in rocks and simply stirring the pot again might bring life back to the planet within a couple centuries instead of many millennia that most methods would take.
This video of Mars Insight is truly mind-blowing and amazing. And to hear the recorded quake, wind rush and the movements of the robotic arms and other instruments for us lay people so far, far away from Mars was truly breath taking. This is truly rocket science. So, hats off to these brilliant scientists, aeronautics and computer experts and engineers, for the excellent work they are doing, educating us and keeping us informed of scientific and space exploration and progress. 💯💥💫👌👍
To address a complaint seen in a lot of comments: dust on solar panels was a problem for earlier missions. The newer Mars rovers use Radioisotope Thermoelectric Generators and are not reliant on solar power. 🚀
If you think about the entire weight of an atmosphere being stripped away from a rocky body with a liquid core. The crust would expand and create fractures that could go all the way down to the core. If you take heat and the elements found there into account it would be at a much higher pressure than the surface. So the magma would ooze out like a gusher on its way to a low pressure area. This could also explain the vast amount of unground water that we have detected. The planet quite literally opened up on the inside and some of the surface water found its way in before it was stripped away.
At sea level, we're only 14 pounds per square inch from hard vacuum. Mars never had near that much air pressure. I don't know that the pressure loss had much effect in it's solid body. Mars's gravity couldn't have been affected much.
Living in country where we get deep cold in winter (sometimes dipping down to minus 40 Celsius in December to February here in Montreal) I’m amazed to see scientists re-create the soil conditions with loose soil back on earth. Even the driest of soil (even soil containing just the slightest amount of moisture ) freezes rockhard in the dead of winter.
That is probably the exact core of the problem. However, when they startet the InSight mission, they had no idea how common water actually is in our sol system.
Did anyone notice that the team members checking the retractable solar panels had black cables sticking out of their suits attached to small poles? Some on the wrist, some on the back, and some on the chest or neck. I assume these are grounding cables for electrostatic discharge so as not to affect the equipment's sensitive electronics - or does anyone have another idea?
It still boggles the mind how the InSight team didn't think to implement an integrated plan B option for the case of the stuck digging mole. Something as simple as making it retractable by tether or claw in case it got stuck or hit rock or even fell over on the surface, case in point.
Likewise deploying solar panels in a known dusty environment and hoping that some spurious 'dust-devil' would come along and give them a good clean! Solar panels 101, they need to be kept clean. I'm seething at the awesome ingenuity compromised by incredible stupidity!
@@conmcgrath7174 I couldn't call it "incredible stupidity" when the majority of the lander lasted longer than expected, but I'm still puzzled. I can't understand why it had by far the most powerful solar panels of any lander or even rover to date. Why did it need so much more power than even a 1-ton rover? Could it have been designed to use less power, so the solar panels could have taken less of the mass budget, allowing the mole to be heavier and more complex? (Just being heavier might have helped it burrow.)
Crazy how there can be technology that provides working signal between earth and mars yet the router in my garage struggles to give me wifi on the toilet.
With all the tech used for probes and rovers, why haven't they stocked any of them with a simple brush? They got robot arms and drills and seismographs, super high tech gizmos, but they let dust block the solar panels as if there's no solution..
I know right? Or even an air powered cleaner to blast the dust off? Like a reverse hoover/air jetwash? They have rockets strong enough to land vertically, surely they could make an air jet to blow away the dust. Tbh they've wasted trillions over my lifetime alone on Mars Missions, taking pictures of dust 🙄🥱
That is the"problem" with supersmart techies... They can invent the most incredible things but overlook a simple everyday object. It has happened often enough a million dollar projects was halted or failed due to the lack of some simple "no tech" items. Smart people are not always bright people ;) heck...dare I say... if they would think of bringing a brush or cleaning cloth, they would first engineeer it into oblivion
@@Mike-wu7ie thats the wrong answer. It has to do with static charge. because gravity is less, static attraction is stronger, and just like the regolith on the moon, they needs brushes that dont cause a charge when ran along a surface, because dust buildup in the grooves and and seams on the rover would cause it to break faster. Did the research and spoke to a professional instead of guessing like you did. Its the "same" dust, just affected differently due to less gravity, and less atmosphere to help with passive dispersion.
@@Mike-wu7ie its ok to rephrase exactly what i just said. but fwi, we got all the same sized dust on our planet, and we use ultra fine particles to run experiments in labs. The only differences are gravity, and atmosphere. Unless you mean to say mars has its own periodic table, and uses different physics. But if i say its static charge, and you say "no its static charge", then whats the point?
I think you folks are awesome. I wish I was a 16 or 17 year old kid looking to follow in your footsteps, but im not i grew up with Gemini & Apollo. But I'm so excited by what y'all are doing. God bless you & keep up the great work ! 🫡 🇺🇸
What Insight need was plastic covering its solar cells that could be rotated through a brush capable of removing the dust. That’s extra weight, of course. But space launches are getting cheaper.
The narration is unbearably paternalistic, the voice is emotionally disturbing and the information is anything but concise and so inefficiently delivered that the video is unwatchable…

I was awoken two days ago by a Magnitude 5.0 quake in Bukidnon Mindanao, more than an hour's drive south from where I live. Here in the Philippines earthquakes are common. What is a large quake on Mars hardly rates a mention here. Hats off to NASA for a successful mission!

@@vomm the dust doesn't jusdt 'fall off', martian and lunar dust stick to things like glue due to static charge
@@vomm That's not how dust works; people with glasses can't just shake dust off of their glasses even on earth, same situation with SP's
You'd think by now we'd include some way to dust the panels off.
That was a problem for earlier missions. The newer Mars rovers use Radioisotope Thermoelectric Generators and are not reliant on solar power. 🚀
Yeah they should use the drones propellers while attached to the Mars Rover to remove the dust!
They've got to save some turn of the century tech for the next century

You have such remarkable content to share. We look forward to seeing more insightful content like this.
I figured I'd be skimming one 50-minute video about rocks on Mars. (Rocks...for 50 minutes...really? Yes, really!)
Three videos watched straight through and almost two hours later, I've just subscribed.
Very well presented and compelling content. The "humanizing" of these scientific instruments complimented in other comments really isn't over-done, either.
*Mars will do what it must to repel all invaders.*
😆
Mars is completely inhabited by robots
*makes bigger sandstorm*
@@cyberwop haha misi- ...
*oh wait its true*
@@cyberwop well i slightly disagree. We definitely have introduced single celled organisms like bacteria to Mars when we introduced robots. Mars probably hides single celled life too. Everything is possible.
I used to work as a fence builder.
In New England, instead of digging, we used pneumatic air hammers to pound steel pipes into the ground for our posts.
Dirt is unpredictable. One rock can throw you off. It was a two man job, with one man on the trigger and another just keeping the post straight. But the most important factor was gravity - the more your hammer weighed, the better it would drive that steel into the ground.
I wish the NASA techs could have known this before attempting to bring a hammer to Mars light enough for a space craft!
the “machines” humans are creating are absolutely incredible. i love find out about our sister planets. when i was a kid in the ‘50’s, Mars still had canals. (read Ray Bradbury’s Mars Chronicles. they’re quite dated, but Martians are fascinating.) :) ☄️
@feralblues,
In Solaris, an intelligent planet conjures up and materializes memories of humans. I feel that Bradbury's Mars - or its indigenous life forms, the 'dark and golden eyed' - works in the same psychological way.
Bradbury's Chronicles are poetic and have a rural American feel; a "sitting on porches in the evening and drinking dandelion wine" kind of atrmosphere. The rockets that bring the colonists from Earth are never described in detail, It's like the Earth people even imagined their space ships. Same with the oxygen and autumnal weather conditions. Ray was at least so subtle to not call Mars "Barsoom"...
Me and my space head 4yr old loved this. Excited to have found your channel!
I followed this whole mission via Twitter so this was great to read it all stitched together with far more depth thank you very much for this awesome video
1.3 Million viewers. Yours is the best channel on youtube.
Good helpful mission summary: thank you, it is wonderful to have your terrific sorting of 'things' into a sensible prioritized order.
Am I the only one who plays Astrum to fall asleep? Alex's voice is so calming. I love to listen to Astrum especially when it's raining ✨
I love your videos. I was really into astronomy as a child. Today, my expertise is cartography and earth science, but I love listening to your videos while I work.
I love this channel. Awesome info…..it shows how much we still have to go in understanding Mars, let alone in understanding the universe…..HIGH 5
I can’t wait to see what is in the cave systems of mars
probably rocks
Myname jeff

Martians of course
Thanks for the video. Great quality, Thoroughly enjoyed it :)
You should think about interactive kids books with that storytelling :D
Amazing content. Enjoy your writing the most.
To me this has all told me Terraforming Mars would be far easier than expected as it might be as easy as breaking the surface crust up and getting it moving again at which point the atmosphere will thicken, water will start to be released in mass quantities as much is under ground and locked in rocks and simply stirring the pot again might bring life back to the planet within a couple centuries instead of many millennia that most methods would take.
This video of Mars Insight is truly mind-blowing and amazing. And to hear the recorded quake, wind rush and the movements of the robotic arms and other instruments for us lay people so far, far away from Mars was truly breath taking. This is truly rocket science. So, hats off to these brilliant scientists, aeronautics and computer experts and engineers, for the excellent work they are doing, educating us and keeping us informed of scientific and space exploration and progress. 💯💥💫👌👍
To address a complaint seen in a lot of comments: dust on solar panels was a problem for earlier missions. The newer Mars rovers use Radioisotope Thermoelectric Generators and are not reliant on solar power. 🚀
now this is a very good channel. always looked for one like this one and finally found it
If you think about the entire weight of an atmosphere being stripped away from a rocky body with a liquid core. The crust would expand and create fractures that could go all the way down to the core. If you take heat and the elements found there into account it would be at a much higher pressure than the surface. So the magma would ooze out like a gusher on its way to a low pressure area.
This could also explain the vast amount of unground water that we have detected. The planet quite literally opened up on the inside and some of the surface water found its way in before it was stripped away.
That actually makes a lot of sense
At sea level, we're only 14 pounds per square inch from hard vacuum. Mars never had near that much air pressure. I don't know that the pressure loss had much effect in it's solid body. Mars's gravity couldn't have been affected much.
Living in country where we get deep cold in winter (sometimes dipping down to minus 40 Celsius in December to February here in Montreal) I’m amazed to see scientists re-create the soil conditions with loose soil back on earth. Even the driest of soil (even soil containing just the slightest amount of moisture ) freezes rockhard in the dead of winter.
That is probably the exact core of the problem. However, when they startet the InSight mission, they had no idea how common water actually is in our sol system.
Nasa honestly needs to start building in cleaning measures to their rovers and landers
The best channel in utube. Well done dude!
Did anyone notice that the team members checking the retractable solar panels had black cables sticking out of their suits attached to small poles? Some on the wrist, some on the back, and some on the chest or neck. I assume these are grounding cables for electrostatic discharge so as not to affect the equipment's sensitive electronics - or does anyone have another idea?
Possible, used in electronic repair and manufactuting.
Thank you bro ❤️😀 i always love the way you present in your videos. Even now i love space science more n more ❤️❤️ love from India 🇮🇳
It still boggles the mind how the InSight team didn't think to implement an integrated plan B option for the case of the stuck digging mole. Something as simple as making it retractable by tether or claw in case it got stuck or hit rock or even fell over on the surface, case in point.
Likewise deploying solar panels in a known dusty environment and hoping that some spurious 'dust-devil' would come along and give them a good clean! Solar panels 101, they need to be kept clean. I'm seething at the awesome ingenuity compromised by incredible stupidity!
@@conmcgrath7174 I couldn't call it "incredible stupidity" when the majority of the lander lasted longer than expected, but I'm still puzzled. I can't understand why it had by far the most powerful solar panels of any lander or even rover to date. Why did it need so much more power than even a 1-ton rover? Could it have been designed to use less power, so the solar panels could have taken less of the mass budget, allowing the mole to be heavier and more complex? (Just being heavier might have helped it burrow.)
With how often dust becomes a problem for any kind of mars lander/rover...you'd think they might come up with an idea to combat it at some point.
They have. The newer Mars rovers use Radioisotope Thermoelectric Generators and are not reliant on solar power. 🚀
@@TheStockwell Nice to hear, didn't know that!
Maybe like a windshield wiper for the solar panels, the mission could have lasted years longer than it has.
I was wondering whether the helicopter they had on the most recent Mars mission would be of use in blowing dust off the solar panels?
@@TheStockwell impressive knowledge! thanks for sharing
I eagerly await a video from this channel everyday!
Crazy how there can be technology that provides working signal between earth and mars yet the router in my garage struggles to give me wifi on the toilet.
It’s all nonsense yeah
With all the tech used for probes and rovers, why haven't they stocked any of them with a simple brush? They got robot arms and drills and seismographs, super high tech gizmos, but they let dust block the solar panels as if there's no solution..
I know right? Or even an air powered cleaner to blast the dust off? Like a reverse hoover/air jetwash? They have rockets strong enough to land vertically, surely they could make an air jet to blow away the dust. Tbh they've wasted trillions over my lifetime alone on Mars Missions, taking pictures of dust 🙄🥱
That is the"problem" with supersmart techies... They can invent the most incredible things but overlook a simple everyday object. It has happened often enough a million dollar projects was halted or failed due to the lack of some simple "no tech" items.
Smart people are not always bright people ;)
heck...dare I say... if they would think of bringing a brush or cleaning cloth, they would first engineeer it into oblivion
@@Mike-wu7ie thats the wrong answer. It has to do with static charge. because gravity is less, static attraction is stronger, and just like the regolith on the moon, they needs brushes that dont cause a charge when ran along a surface, because dust buildup in the grooves and and seams on the rover would cause it to break faster. Did the research and spoke to a professional instead of guessing like you did. Its the "same" dust, just affected differently due to less gravity, and less atmosphere to help with passive dispersion.
@@Mike-wu7ie its ok to rephrase exactly what i just said. but fwi, we got all the same sized dust on our planet, and we use ultra fine particles to run experiments in labs. The only differences are gravity, and atmosphere. Unless you mean to say mars has its own periodic table, and uses different physics. But if i say its static charge, and you say "no its static charge", then whats the point?
Amazing ,Pure science fiction
Wonderful illustration.
I am really curious about mars

@@dhamcaleb8684 oh so what i have to laugh
I'm more curious about Uranus.☻
@@pragyarai9363 depends..up to you gona be uptight for no reason about it?
i am curious about the insight and perserverance of mars.
... superb presentation... bravo Astrum!
Unforgivable oversight not being able to clean the panels.
That was a problem for earlier missions. The newer Mars rovers use Radioisotope Thermoelectric Generators and are not reliant on solar power. 🚀
I think you folks are awesome. I wish I was a 16 or 17 year old kid looking to follow in your footsteps, but im not i grew up with Gemini & Apollo. But I'm so excited by what y'all are doing. God bless you & keep up the great work ! 🫡 🇺🇸

Those two little cubesats remind me of the probes from Star Trek.
•••√√ Hit 120k today. Thanks you for all the knowledge and nuggets you had thrown my way over the last months. Started with 14k in March 2022.......
Have been hearing about Mrs JenniferAnnaa and her genius mind in the crypto market also how good is she?
What Insight need was plastic covering its solar cells that could be rotated through a brush capable of removing the dust. That’s extra weight, of course. But space launches are getting cheaper.
And still people talk of colonizing Mars?
No one except children say this
Awesome video! The way you made it, it gives life to the Mars project
The narration is unbearably paternalistic, the voice is emotionally disturbing and the information is anything but concise and so inefficiently delivered that the video is unwatchable…
Einen grossen Lob und Respekt an Amerikanische Wissenschaftler für eure harte Arbeit , ihr seid die Besten!!!💐👍🙏
A lot of money spent just dig a little hole .
Money is meant to be spent, isn't it?
Excellent commentary. Not one moment of boredom!
Currently life has been so hard with all the average persons due to the Russian and Ukrainian war their how been so much economic crisis but l believe this is the best time to look up to digital currency investment stock marketing is good 😊
Yes crypto is better l have a holding asset in crypto
dont kid yourself kid the politicians are getting rich off wars. they have no hardship
@Coin Bureau l'm in a long term trade with him l only withdraw every 6 months and I've made about $90.000 since last year November it's okay for me he's a good man to work with
He's success stories is everywhere even in Twitter and Linkedin
I started working with him with 3000usd and I do withdraw my profit of 17,000usd every week
A hot day on Mars is only 2 degrees colder than winter here in Minnesota! Love it
I was awoken two days ago by a Magnitude 5.0 quake in Bukidnon Mindanao, more than an hour's drive south from where I live. Here in the Philippines earthquakes are common. What is a large quake on Mars hardly rates a mention here. Hats off to NASA for a successful mission!
This was an amazing video!! Thank you.
Id love to know you better, thats if you dont mind
Thank you for another wonderful video! :)
