[Technology] NASA Perseverance Mars Landing!

[Pint of Ale and a Burger]

Staying away from chocolate for a minute and to be serious, can they swing the camera round and show Earth from Mars like we can see Mars from Earth, as I have no idea about this sort of thing.
Are there any temperature readings, atmosphere readings (oxygen, nitrogen etc) gravity.
This stuff is probably already known but because of this I am now very interested in what Mars is like.

There is a lot of good information here in the link regarding mission objective and key instruments on board the perseverance.

Also it's worth keeping an eye on the NASA live press briefings as they have an interesting QandA afterwards in which members of the public can tweet questions.
It's definitely an event that has captured the imagination as you say it's got a lot of people very interested in mars.including myself.

Its cold as **** and they (who?) only have a little bit of oxygen over there. Its a shite planet.

Yes it can be quite chilly on Mars down to -80 farenhiet.but I read today that where the rover is today it's temperature is the same as Texas at the moment,which surprised me.
I think I could cope with that with a decent jacket and a wolly hat and gloves.

The preparation that has gone into this mission is really bearing fruit. It was a masterstroke to acclimatise the rover to this hostile climate by spending a month roaming the wilderness of Croydon.

We could terraform it one day.

I will be enjoying death by then

That is Curiosity and the audio is undetermined.

Mars is probably pretty good as planets go, at least something can land on it rather than sink into ammonia or some such chemical.

It’s just that Earth is extraordinarily beautiful in comparison to any other we know about so far

Yes so lets spend all these brains and money on helping it rather than muppeting around in some cold desert

Yes, we're doing such a good job with our own planet.

 

[SeagullinExile]

Yes, we're doing such a good job with our own planet.

Way too late to do anything about that now, gone beyond the tipping point. Hence the need for space exploration - We will need to find a new home eventually, when our current one gives up the ghost.

That is no reason to prevent any and all future space exploration. Not to mention safeguarding our species survival.

Don’t forget it’s America paying for this, and of the entire US Govt spending NASA has a whopping 0.48% budget.

Plenty of places to cut costs first if you’re concerned about NASAs spending. ie the Military.

Sure, if they cut the military spending in half or something I would have no complaints about throwing some money on Elon Musks perverted fantasies.

Elon is not involved in this of course.. [emoji6]

All it takes is one meteor which we wouldn’t see until it was too late and boom: human civilisation wiped out.

And if that still ain’t anyone’s bag (or you don’t care about survival of the human race), most of the technical gizmos you use in your day to day likely came about due to Space endeavours.

We have to work on the basis that the damage to Earth is not yet irreversible - it's certainly a far better starting point than any planet you're likely to find. The idea of a handful of humans living by themselves on an alien planet isn't something I'd like to call "home". That said, I'm fully behind space exploration for the sake of exploration itself.

I never suggested stopping space exploration - I'm fully behind it.

But if we want to safeguard our species' survival (and hopefully all the other species on this planet), I think there needs to be an agreed definition of "survival" . Most of what I hear is science fiction nonsense.

Unfortunately Elon Musk's fantasies involve funding coups to overthrow democratic governments, when they threaten to use their natural resources to fund a welfare state.
