Mars Rover landing 3:55pm Eastern

nasa is going to have to seriously look into building these crafts out of biodegradable materials. What a mess they have made.

The Mars tourism industry may never recover.

The government should contract with Carnival to design the first Mars ship to book curious travelers. I bet they could get the price point down to around $1200 per adult with an interior room and no view.

Just don't let Howards date drive it.

The first audio recording of a sound from another planet

that might have been a bit anti-climactic. no peegasms were had during the listening to that.

What did you expect to hear. Howling monkeys way off in the distance?

That’s pretty cool. I read that the daytime temperature on the equator on Mars is about 70 so you could walk around in shorts and a t shirt. Until night, then you would freeze to death.

Sounds like Texas

The first audio recording of a sound from another planet

I find this so incredible. I've listened over and over. *possible stupid question* coming I mean, space is a vacuum, so how is there sound? I'm amazed that we can even record sound on Mars. Is this the first time ever hearing space?

Mars has a thin atmosphere so you still can hear sound. It would probably be much fainter and higher pitch than you would hear e on Earth

Mars has a very thin atmosphere, mostly carbon dioxide. After the core of Mars cooled, it lost its magnetic field and lighter gasses were either stripped or floated away. Being mostly CO2, sounds will not sound the same as on earth. The atmosphere being less dense means sound travels slower, around 500 mph, and it does not carry higher pitched noises very well, so all sounds would "sound" lower.

Someone noticed the rover has a family of rover stickers -

Thanks it's really fascinating.

When I read this stuff, I think about technical divers who use helium with their oxygen when deep diving (actually called Trimix-though the stuff that has no nitrogen is apparently called Heliox). They sound like Alvin and the Chipmunks when talking to topside.

What if you shot a bullet on Mars. Say an AR-15. On earth you chornograph the bullet at 2700 fps. Would that same bullet travel slower on Mars?

You'd think it might travel faster. It sure as hell could travel farther, since there's less air resistance (not to mention the lower gravity too).

P.S. Searching, and the gravity seems to be more important (62% less), and mostly on distance of travel

[Stapes]

Less atmosphere for resistance less gravity to pull it down to the surface so it would go faster and farther. You would also be able to jump farther as in the documentary John Carter of Mars

So, why doesn't sound travel faster on Mars?

Sound is a mechanical wave, which means that it needs substance to travel through, such as air or water.

These have also been videotaped on Mars

My understanding is that temperature has a lot to do with the speed of sound waves...... so it's pretty cold on Mars... hence the speed of sound would be a little slower. I'm sure woohoo guy will come in and set it straight

is radio a mechanical wave?

Well, he already said that the atmosphere is less dense, which is why sound travels slower. So the "thicker" the atmosphere the faster sound travels. Kind of the opposite of what you would think.
