It is a very impressive accomplishment. Humanity is capable of incredible things.

It really is! TechCrunch did an article about it with more pics including one from the MRO showing it depending with the parachute open!

I believe that Monday NASA will be releasing video of the descent and landing. Video may have been captured from four different cameras/angles at some different and some overlapping stages of the process.

Did they send the video crew beforehand?

It will be super groovy if they stitch them together like some of these car cameras do, to show the terrain beneath the lander.

Here's a timeline of which cameras should have been active during descent:



Regarding the abbreviated names on that image:

There are 5 types of EDL documentation cameras: The Parachute Uplook Cameras (PUCs, quantity 3), the Descent stage Downlook Camera (DDC, quantity 1), the Rover Uplook Camera (RUC, quantity 1), the Rover Descent Camera (RDC, quantity 1), and the Lander Vision System (LVS) Camera (LCAM, quantity 1).

Raw image cache from the rover!

Apparently this will be updated regularly and you can do what you want with them. At least that is how I understand it. Either way, cool to see.

An audio clip is out of wind on Mars now too. It sounds like wind on Earth really.

Well, the atmosphere is so much thinner that it probably takes a lot more wind to get the same sound?

CNet article that links to a tweet that embeds a TikTok....

Short version if you don't want to travel down the rabbit hole: The message reads "Dare mighty things," a slogan of NASA's Jet Propulsion Laboratory (JPL), while a JPL's Paul Ramirez revealed that the outer rings included GPS coordinates for its offices in Pasadena, California.

I'm loving the attention to detail in these little things. It is really cool if you asked me!

Direct link to the discoverer's original tweet:

And his initial explanation:


And direct link to Paul Ramirez's tweet about the coordinates:

And a confirmation tweet from Adam Steltzner, Chief Engineer for Perserverance:

I love that the rover engineering team put hidden messages like this for folks to discover. I wonder if there are any others hidden elsewhere.

Beneath the rover and in very small letters is the following message:

"We come in peace … and we leave trash everywhere!"

And if it had been up to me, there would have been a little cubby that would drop an empty water bottle someplace obscure.

I found out yesterday that the microphones on Perseverance are just off-the-shelf DPA 4006 mics, just like we often specify on our projects. I had assumed they were custom-made for the different atmospheric conditions, but apparently not!

Holy cow they did it!



Congratulations to SpaceX on an absolutely remarkable launch and landing. I'm impressed! And this after an aborted launch.

These guys are awesome!

Edit: The ending is funny as hell! But you have to get that video elsewhere.

Start watching at the 8:26:00 mark.

Some landing legs didn't lock into place, part of SN10 landed on the skirt. Must have done some damage to the tank or lines going into the Raptor caused a methane leak, and like with SN4, found a hot spot and went boom.

Regardless awesome success despite the demise. SpaceX already knows the landing legs suck and need redesigning. Shame it cost them SN10 cause I am sure they would have loved to inspect the hell out of it, but they did it.

It truly is amazing, and there is a lot more intact debris to examine this time around.
