View Full Version : Mars Landing
I remember the first moon landing, my dad let me stay up all night to watch the broadcasts.
This video of the Mars Perseverance landing was taken with off the shelf cameras mounted on the lander. It was a bootleg project, not mission
critical and not really expected to work, but worked flawlessly.

Pretty cool first ever color photos and much more to come. However has anyone else noticed all the conspiracy theorists are already saying its fake. Makes me laugh at how stupid people can be.

At least they didn’t mix up metric & imperial units of measurement again...........

Tru dat........
It seems very inhospitable, and I am not sure what we have to gain by going to Mars, again.
I did watch a Nova show about this, and apparently they are looking for "proof of life" on Mars.
They are looking to see if 3-3.5 Billion Years Ago, microbes lived on Mars.
I wouldn't say this is expensive (something over a billion dollars) in our Corona Virus world of Trillions of dollars being spent.

I think the Mars landing is awesome. I watched it live and was pumped. The "was there life on Mars?" question is silly and not important IMO. It's just an academic history question. It doesn't matter if there WAS. What matters is what is true now. IS there water? What other valuable minerals can be found there? Are there currently microbes that will kill the human race if they are brought back to earth? Things like that.
However, the technological lessons learned from this and previous landings are invaluable. The next steps are to make a return trip from Mars which is a big deal. Space travel is worthless until we can figure out how to bring material and people home. Once we can do that, we'll start to see the benefits of space travel. This landing is a huge step in that direction. Plus, they put a freaking drone helicopter on Mars too. That's just awesome.
I LOVE when the USA does extraordinary things. Especially after the MSM was totally excited about the UAE "beating NASA to Mars" as one headline put it. The UAE probe made it there a few days before, took a picture and the world acted like it was a huge deal. It wasn't. The UAE probe was designed and built in Colorado and launched on a Japanese rocket. The UAE just funded it and put their sticker on it. Hardly a historic accomplishment. Suck it media, the USA still kicks ass in space.
So...does this make Mars the only planet solely enhabited by robots?

There's still a lot we don't know about Mars. We have barely touched it and we need to know a lot more if we're ever going send humans there. We do need to extend humanity outside Earth's cradle before we get a planet killer impact again and Mars has the advantage of having reasonable gravity and the ability to hold onto some form of atmosphere.
Simply enabling the voyage to Mars will necessitate advances in safety, medical, and ecological technologies which will benefit all the humans living on THIS rock. Estimates are that every dollar spent on the Apollo program returned over seven dollars to the US economy (some estimates are much higher).

Because we are humans and that is what we do!

When you consider all the advancements made tech wise, from just going in to space. Yes it is. Or should we stick with bidens handing 4 billion over to mexico, for helping heal central & south Americas woes? My money's on space.
In the long run who knows how "mankind" or is that multigendernonspecificgrouphugkind the word i should have used.

like the ones that believe a spacecraft just landed on mars?
At least they didn?t mix up metric & imperial units of measurement again...........
I was mentioning that to my coworkers.
?We intend to put the lander on the surface of Mars.?
NAILED IT!!!
You exceeded expectations since some of it is under the surface.
Let me know when they get to the part where they encounter the protomolecule.
I think every software developer views planetary landings with extreme dread.
We've (developers) all have extensively tested stuff we were proud of and expected it to work. And 100% of the time, something will be f%$%ed that needs debugged. Imagine relying on 10,000 individual systems that are, in fact, no better than alpha tested until it finally gets it's ultra-billion dollar ass to another planet, with telemetry delays of over 15 minutes (speed of light over, and back). And by alpha tested, I mean there is never an actual, complete, working test of all components together until it's there. Just "simulated". Here, something starts to go wrong you could pull the plug. There, dust is already settling from it's impact crater by the time the information gets to you that something was wrong at the beginning of its decent.
It is honestly mind blowing that there isn't more cases of "failed to convert between metric and imperial", or more likely, "some dingleberry forgot a f$#$ing semicolon" and "his dip$h!t friend didn't close a rarely-used loop" in the space program, considering how much code must go into these things now.
While the last/current Mars lander is a feat of technology, i am somewhat taken aback by "this is the firstust like this" commentary. Over a dozen craft have landed on Mars, some 8-9 of them have had roving capability. As for the color images, are all the color images sent in previous landings... fake? Or just not of the coolth HD ?
Honestly curious.
For those that discount the value of the space program (like family members), let them know that China is spending more in aerospace in the just the next few years than we have in the last sixty. They have inordinate factors of magnitude more people working hard in their schools and universities than we do. It's easy to look at today's picture and say "it doesn't matter".
Will they feel like space still isn't important when China masters relativistic flight before us? That's so, so much more dangerous than being the only country in the world with nuclear weapons. And if anyone doubts that is possible, there's already something - and more than likely, several somethings - that have mastered it. Dig into all the tic tac encounters with our carrier and air groups in 2004, 2007, middle east, etc, much of which is fully acknowledged by the US Navy. Something has relativistic flight and it isn't us.

the protomolecule was found on phoebe, before hitting ceres hard. Mars tried to steal it. belta forever!

Haven't exactly been following along, but I think there are a couple things. One, first rover with an additional flying drone. Second, ability for semi-autonomous pathing for said flyer (since the delay would make flying it from the command center impossible). Third, I think this is the most complete video we've had of the touchdown, and I think the only such footage in color (like, I think some previous rovers' cameras capture color, but not the landing craft itself, which was all black-and-white).
(since the delay would make flying it from the command center impossible).
You're not kidding. Currently about a 40 minute round trip for any kind of feedback/control, and the maximum flight time is...
Wait for it...
90 seconds.

So what was the secret message in the parachute? I saw an article headline on Space.com talking about it, but didn't read it.

I was wondering what the parachute said too. It was obvious to me that the pattern meant something but I didn't find out until today.
It's a rorschach test for Martians....
Pretty damn cool but very geekish.
What do the numbers and individual characters mean?

What do the numbers and individual characters mean?The numbers are the coordinates for the JPL. You know, to make it easier for the martians to find it when they want to attack.
Letters are "Dare mighty things".
I meant the W and N around the outside, but I assume those are part of the coordinates.
Parachute and decelerating thruster due to much higher terminal vel.
So some kids can hypothesize that venus do not need deecererating thruster due to much higher atmosphere than earth.
No. You probably need thruster everywhere to correct it from crazy winds. (Not to mention crazy pressure and temp).
Even though the surface gravity on Mars is only 3.7 meters/sec (compared to 9.8 meters/sec on Earth), the thin atmosphere means that the average terminal velocity hits a nail-biting 1,000 km/hour or so, compared to about 200 km/hour back home. That means you have to do a lot more work to shed speed.

Eta; it is meter per second squared..... not m/s.

I hear there are a few of those at NASA and JPL :)

North Latitude
West Longitude
If the Martians read those coordinates backwards, they'll wind up in the north Atlantic ocean.

Beltas with a MCRN frigate better than visiting the inners bossman.
