that would be a first
And no doubt Russia has gone the cheap way, and bought a $2000 unit thrown it on top of a top secret Mars mission, rover, and hacked the software.
Flys for a good half hour, unless it hits a tree?

China has revealed plans for what it is calling a "Mars cruise drone", and it looks very familiar to another flying vehicle we all know and love traversing the skies of the Red Planet right now.

If they--or Buzz Aldrin--had encountered the situations you described, survival would have been strictly a matter of luck.
If he had he would have sealed up the suits with tape, contacted Mission control and tried to dock with the ISS, instead of losing his head, bawling his eyes out, and probably burning up on reentry.
Your name does you justice.
I've suggested before the Biden administration is actively seeking to stymie Space X.
The tension is now out in the open. Musk has criticised "sleepy Joe" for failing to congratulate his company and people on this highly successful mission, the first of its kind, and a testimony to the US's continuing ability to make major technological advances, not least by attracting the brightest and best from all around the world (something China or Russia can never do).
Probably becuase Musk won't touch his jab, and just like our Premier is having a temper tantrum.

Thanks tahanson43206, SpaceNut, no l was tired, saw this on Skynews, and thought since no one had posted it, it would be a good subject or fit for this forum.
And my definition of "Amateur" is Buzz, having extensive experience in aircraft, and an almost fatal accident, flying a Lunar Lander type jet craft on Earth and he ejected, when it malfunctioned and almost tipped over and killed him.
That helped him while landing on the moon, and ignoring all the computers screaming at him, while he avoided a large rock in the target crater and landing with seconds to spare.
A few months of training is fine, but if they really got into a bad situation, would they still be alive? Or if the engineer had never been in a life and death situation, how would it have been if an asteroid hit the rocket, and they had to get back to Earth with a cracked windscreen, and damaged space suits?
Buzz Aldrin was a professional, since he had proven that he can keep his head, while in a bad situation.

For Tmcom .... your topic here is the best match (I'm hoping) for this update....

SpaceX capsule with world's first all-civilian orbital crew set for splashdown
The Dragon capsule, dubbed Resilience, is scheduled to parachute into the sea around 7 p.m. Eastern time, shortly before sunset, according to SpaceX, the private rocketry company founded by Tesla Inc electric automaker CEO Elon Musk.
According to Google, the planned landing is set for before 11 PM UTC.
I certainly hope the flight is a complete success!
There are plenty more billionaires with $200MM pocket change.
We should see many more such flights if this one goes well.
(th)
Agreed 200m to them is their dream home, and luxury yacht
Its to bad that they did not get to get out of the capsule into another orbiting station even if it was nothing but an inflatable like BEAM least it would have been something.
Four SpaceX space tourists set to return to Earth tonight
Billionaire Jared Isaacman financed the trip, paying SpaceX tens of millions of dollars.
Isaacman, who led the mission, offered the other three seats to strangers:
Hayley Arceneaux, a 29-year-old nurse;
Sian Proctor, a 51-year-old professor; and
Chris Sembroski, a 42-year-old US Air Force veteran.
They would have to sign a disclosure before they could get into the ISS, but true they where higher up than the ISS, so could have visited.
#10 Re: Life on Mars » Seasonal Methane on Mars » 2021-07-28 02:49:55
Methane, mainly comes from the top part of Mars, or any habitable, zones concentrate in the strongest magnetic field areas.
Mars also has plenty of oxygen coming off its surface, which throws mud at NASA's coverstory.

The 15 m-wide first stage main parachute will open while the descent module is still travelling at supersonic speeds, and the 35 m-wide second stage main parachute is deployed once at subsonic speeds.
Hope they change the color.

True there is that, and all they can do is preset a course, (can't fly some thing that will crash in a short while with a 20 minute delay).

#19 Re: Martian Politics and Economy » Apollo 11 site should be granted heritage status, says space agency » 2021-03-22 20:19:53
Interesting article.
“My hope is that humanity is smart enough not to go back to this type of earthly protection. Just protect it. That’s enough. Just protect it and have everybody agree..."
Hmmm...a little naive I think. What about the other Apollo sites? How do you define protection? Can someone set up a hotel at the scene even if they don't muck around with the site itself?
I think there needs to be a formal protection mechanism for the Moon.
Can't now recall what was in the Moon Treaty but I don't think it ever gained many signatures and was pretty useless.
An International Lunar Co-operation Organisation is required I think similar to arrangements for the Antarctic.
I don't think this should serve as a model for Mars - which I want to see create its own sovereign authority.
Agreed, there should be a couple of km's zone around the landing site, where the only tourism is via a hovering bus or space drone, (pretty much destroy it if there is a Maccers on the horizon).

You will have tourists trampling all over the place soon, so some futuristic gangplanks need to be installed, let along pesky, rovers.
Not sure if they can heritage list the Apollo module in space though?
#21 Re: Unmanned probes » Official MSL / Curiosity Rover Thread | Aug 5, 2012 10:31 p.m. PT » 2021-03-13 20:06:51
That occurs when its warm and then suddenly gets colder as it would happen from going from day towards night as the vapor would condense and fall...
Agreed, but l didn't spot any indications of frost before hand, and going by the biggest drop l saw, it pooled under the rovers wires and remained there until someone at JPL moved the rover.
This was most likely after the Martian sun, evaporated most of the raindrops away, (although l found the occasional one or more).
PS Good to hear from you Spacenut, check out my music thread when you can, hit the jackpot recently.

Look at old photos of the original Viking landings and you will find one with frost, taken early in the morning.
https://solarviews.com/cap/mars/frost.htmAs temperatures declined over night, water vapour that had evaporated from the regolith during the day, frosted out on the surface. As temperatures increased throughout the day, it sublimed. Could it melt giving rise to water droplets before it evaporated? Actually, yes. The atmospheric pressure at Curiosity's landing site was found to fluctuate between 690 and 790Pa. The vapour pressure of water at 0°C is 611Pa. If the surface of Mars rocks is contaminated with soluble salts like perchlorate, then frost could melt at temperatures as low as -40°C.
So yes, it is possible for water droplets to form on the surface of Mars. If there is sufficient salt content and the ice melts far beneath the usual freezing point of water, the vapour pressure of the brine (which declines as a function of temperature) could be substantially lower than the local atmospheric pressure on Mars. So it is possible for water droplets to hang around, without imminently freezing due to evapouration.
It doesn't take an elaborate conspiracy theory to explain this. It is plausible under established conditions. It is in fact entirely possible that parts of the Martian surface contain enough liquid water to get muddy at certain times of the year. But that mud would form from saturated brine rather from pure water. It is unlikely to contain microbes, though we won't know for sure until a visiting science team examine the mud under a microscope.
The global average atmospheric pressure on Mars is 610Pa. That is just 1Pa beneath the vapour pressure of pure water at normal freezing point. That is unlikely to be a coincidence. Carbon dioxide is highly soluble in liquid water, forming carbonic acid. Any CO2 dissolving into liquid water on Mars would react with bases in the regolith to form stable carbonates. The low pressure of the Martian atmosphere is likely the result of a long established equilibrium between the atmosphere and frozen water ice.
Except that my video, has water droplets on the rover itself, and no frost before hand.
As l said hard evidence of rain!
Adding all of the other evidence that Mars is not a dead rock!
Ice crystals in those supposed pressures will boil away when they melt, they won't melt first then hold them melt on command.
Yeah, unsubstantiated propaganda!

I do agree that NASA obfuscate. There is no logical reason for using the orange filter and the grid that both obscure detail in photos. It also seems odd that in 50 years NASA have really failed to improve picture quality to any great degree.
On the other hand I don't think they are lying about atmospheric pressures. There is no reason to do that.
There's something going on with NASA - they've spent 50 years denying there's any life on Mars and now, with Perseverance, they seem to have set everything up to announce there is life or has been in the past. Very odd! But I think it might be because NASA have now been captured by the international "planetary protection" mafia.
No Louis, they are, air pressures like earth mean a higher possibility of life, as does the -173 at night one lie, (they moved the decimal point on all of their data, or it is lucky to get down to minus 2 at night not minus 200).
They botch up Viking, then after Carl Sagan went on a monitor rampage, it has been orange screens ever since.
They know that after 50 years of knocking anyone who see's anything weird, as nuts then releases satanic aliens at area 51, propaganda to scare everyone on youtube, (watch PAUL, that movie takes the p...s out of all of that crap) they will have a hard time controlling mass paragrim shifting individuals in shock smashing in any tv store available.
And NASA do release HD images on rare occasions, (check out the last image on the Mars, stealth mission thread).
The answer to the air pressure is in the

Tmcom, would you care to place a wager? I will bet you a tenner that median air pressure on the Martian surface does not exceed 1KPa. If the world discovers otherwise by 2040, say, I will pay up. If not, you pay up. The Chinese are in orbit around Mars right now and must be aware of atmospheric density to be able to design an aerobraking system. Are they also in on the con?
China, Russia and the US, have all made a pact to stay Mum on the subject, so no you will be paying.
I suggest that you watch the video, pure water droplets on the rover, which can only come from rain, and wet sand at the same time to back it up.
The proof is in front of your face, and if NASA wasn't fibbing then why didn't they release this news to the world, answer: they want to release a trickle to the small percentage of the worlds population that can still think rationally, so they can manage the majority that will go ape-shit when this is all released, (well, before 2040).
I suspect that NASA will own up in 12 years time, have your PayPal email ready.

Balancing the available evidence against the need for "extraordinary evidence for extraordinary claims" is tricky at best.
There seem to be both life and non-life explanations for what the instruments on Viking saw.
There seem to be both life and non-life explanations for the purported microbe fossils seen in the Allan Hills 84001 meteorite from Mars.
There may be both life and non-life explanations for the thiophenes seen by Curiosity.
And there's likely more such examples. I dunno, I haven't kept up with all of those.
But there's a trend here: multiple examples over many years of things that may indicate at least past life on Mars. Couple that with the current thinking that life forms fairly easily if liquid water and sunlight are present. Such was true for the first billion years or so on Mars, as best we understand.
My best guess (and guess it is) is that eventually we will find underground living remnant microbe populations on Mars, and fossil traces of widespread earlier surface microbe life on Mars. It will take years of people searching on Mars to uncover all this. But I do believe that eventually we will.

Nope, NASA want to maintain a propaganda regime, and these billion dollar rovers fit their narrative nicely.
I have found pure water droplets on the second last rover, dispelling the air pressure can boil away water myth and strongly hinting at rain.
Or demonstrating that Mars is a lot more earthlike than what they will admit, which makes no sense, on the surface, unless someone or something is living there, and has energy systems, (that we keep burying) that threatens oil profits.
This all sounds pretty far fetched, but Mars is in the habitable zone, and Hubble as well as anyone pointing a telescope at Mars, Always sees a blue atmosphere.
But anyway NASA cannot keep a lid on this forever, or someone who isn't biased will land something there and show the world eventually.
This will all come up soon enough, and scare the hell out of a lot of people who have made a career out of ostriches doing the obvious.
The images in the video are from the rovers raw images, Sol 600+, mast cam.
