If many of you (like me) have struggled to decide the best spot mic for a spacecraft, the choice has been made. The Martian rover, soon to land, is carrying a couple of DPA 4006. Pretty much off-the-shelf, with the exception of a special dust-exclusion grille. If you've followed these probes over the years, you'll know about the wild, multi-mode descent to the Martian surface. In this case, we'll have audio of the whole thing. That's gonna be cool.
I am glad to know what mic to use in this situation. For me, it's usually piano, strings, woodwinds, etc. But you never know when you'll have a client with a spacecraft.

Seems a couple of the panasonic electret elements that earthworks uses and some low noise opamps would have sufficed, but you know the government. Spend 5K$ where 10$ would do..

That's all well and good, but what preamp are they using?

Those will be some fun audio samples to hear if they ever get released.

Certainly true, but I suspect they're going to be using those mics for a lot more than giving us the sounds of the descent. I'd be surprised if they didn't use the sound to tell them a lot about mechanical stresses, turbulence and so on. The NASA and JPL people are masters of data analysis. The mics will also remain active on the surface. Most sound there will be quite low in amplitude because of the thin atmosphere and primary CO2 makeup. So signal-to-noise will be important. Perhaps we'll get something interesting from it.

Meanwhile, most gigging musicians are in total lockdown in many states right here on the ground..... Hard to get excited about Danish mics on a mars rover....

Something exciting to watch from home while we ride this out, IMO.

That's all well and good, but what preamp are they using? I want to know what cable!! I hope it's oxygen free with silver solder and some sort of weird directional braided shield. And maybe some magic rocks to support it.

That's all well and good, but what preamp are they using? Better be a class a preamp with NOS tubes and all oxygen free copper and/or silver wire throughout! Don't cheap out on us now. . . P.S. i don't recall seeing any tender documents for such instrumentation

That's all well and good, but what preamp are they using? Here's from the DPA website: For this partnership, NASA has strenuously tested a variety of mics and chosen a selection of equipment from DPA. The 4006 Omnidirectional Microphones will be the Rover's "ears"; attached to the vehicle and paired with MMP-G Modular Active Cables, which will act as ultra-transparent preamplifiers. Inside the body of the vehicle, acting as the auditory part of the "brain", will be a MMA-A Digital Audio Interface. The MMA-A's job is to digitalize the audio in the highest quality and send it to a computer in the Rover through a USB connection.www.dpamicrophones.com/mars-rover

That's a lot of fancy gear but it would make more sense to invest in acoustic treatment first.
If I was just starting out, like NASA seems to be, I'd get an SM7 and a UA Apollo. Thriller, anyone?
And with the way plugins are, you can honestly add space echo and any Martian mojo ITB.

Knowing this crowd I'm waiting for someone to pop in and say that unless the rover is using an M1 chip, PT and an Apollo that it can't possibly work right. Then everyone clapped.

That's all well and good, but what preamp are they using? I think a nice tube preamp would be the best... of course the tubes would come loose on impact and NASA would have to spend a billion dollars to design and send a robot to go up there to reseat the tubes but the way it would warm up the cold, cold moon audio would be worth it.

LOL... In all seriousness, the fact that NASA is using DPA mics and gear is really very cool.

Yeah but they scrub all that Data as to not reveal things they don’t want the public to see/know...so we mostly see the low resolution versions of everything. They do that, partly, as to not reveal the extent of their tech. Or so they don’t accidentally reveal the location of secret military base X/Y/Z etc.

Crazy huh? All the data is technically publicly owned but they do absolutely withhold it and they get sued all the time for doing so.
