Leo thinks that complex thinking is when he rationalized his hypocrisy.

Leo with a youtube video? He says no to youtube
That wasnt a NASA project you tool, and is irrelevent to the didcussion.

What difference does that make?
If NASA was concerned with SpaceX "spreading life thru the galaxy with his "Tesla", do you think they would have allowed him to launch it?
Why not just answer the fucking question? Youve never posted a coherent argument why Bobs statement is so absurd, but if it is why is NASA spending billions trying to prevent it? Just keep pretending you dont know why Im posting links to NASA.
What a life sink you are.
Its unknown that
A. they have the legal authority to stop him
B. He didnt follow their sterilization protocols
C. His vehicle is going somewhere they are worried about.
Geez that forbes article is a whole lot of nothing.There are only two things that I know of that can make someone say such stupid and idiotic things.. One is religion, the other is drugs.. Which one is it for you? Pull your head out of your ass before the lack of oxygen causes MORE brain damage.

Hmm... I have answered the question, you apparently did not understand the answer.. I will try again and dumb it down even further this time because you don't seem to understand.
NASA is certainly concerned with organisms on their space probes, but not because they're concerned about "spreading life thru the galaxy". That is not even possible within any reasonable human or geologic time frame we would ever be concerned about.
NASA's contamination concerns have two basic flavors..
1) The first (and by far the most important) is instrumentation. The instruments on space probes are ridiculously sensitive, some of them are so sensitive that a single photon could affect them, others could be affected by any sort of chemical or biological contamination.
If NASA somehow magically knew that a biological contaminate would remain in a corner of some bracket and never move, they wouldn't care about it.. But that's not possible, and the rigors of launch (and landing) can shake contaminants loose (including dust), and cause them to interfere with sensors.
2) Planetary contamination. Without any respect to the instruments or sensors mentioned above, NASA doesn't want to land a probe on Mars only to have some bacteria fall off and trick a sensor into thinking it found life. Of less concern, is that such a bacteria could possibly multiply on the planet. Theoretically it might be possible, but very unlikely anywhere NASA has been. On Venus, the high temperature would sterilize the probe, and on Mars, the radiation would do it. Mar's doesn't have a significant sized moon, therefor its core stopped sloshing around and cooled, which caused Mars's electromagnetic field to collapse, which then allowed solar winds and cosmic radiation to make it to the surface after they blew away the atmosphere, which then sterilized the crap out of everything on the surface.
If there was ever life on Mars, then most likely that life was also in the atmosphere and some of it got blown away by the solar winds.. Would that life survive floating around in space? Most likely not.. There is no life we know of that can survive the radiation in space for any time frame measured in the millions of years. Cosmic rays destroy everything.. The energy in a cosmic ray can be thousands of times higher than anything the Large Hadron Collider can produce.. Thousands of times! If we ever ran into a life form that could survive that type of energetic radiation, it would make the alien in the movie "Alien", look like a delicate and fragile marshmallow.
Humans are not technologically advanced enough to get a spacecraft out of our own solar system in any reasonable amount of time. And even if we could, there is nothing I'm aware of on our planet that is capable of surviving the radiation in space... and once you leave our Sun's magnetic field, that radiation gets dialed up to ridiculous. Could a bacteria survive? Yes, but it would take a very special set of circumstances to do it. First, the organism would have to be the type that can put itself into dormancy for millions of years, and second, it would need to somehow be protected from that radiation by very thick layers of dense material. None of which exists on any spacecraft NASA sends out.
Even with most "panspermia" theories, very special circumstances must exist.. In our own planet, we know that when we drill cores down several hundreds of feet (even miles!), we find bacteria in some places.. Very specialized bacteria that evolved to live within the structure of rocks, even some very warm rocks at those depths. Problem is, at those depths, there is no radiation because of all the rock above the bacteria, which shields it.. and therefor, it is unlikely that such an organism would evolve repair mechanisms. Humans can survive low levels of radioactive exposure because we have evolved with repair mechanisms within our DNA. When we're exposed to too much of that radiation, our repair mechanisms can't keep up and we die.
Radiation is zipping through you right now as you read this.. If you want to actually see it, you can build yourself a cloud chamber. Fairly easy to do and a great science experiment.
Now imagine a planet orbiting a star with life.. and a giant space rock slams into it sending up a plume of dust and debris. If some of those chunks of material have bacteria inside them, and if (BIG IF), that material can achieve escape velocity of its host planet, then it could theoretically get a slingshot boost from another planet, leave its host solar system, travel through the vast distances between stars, and be captured by the gravitational influence of another star.. and then land on a planet with the environment needed to host that bacteria. But there's a big catch.. first, that bacteria would need to be surrounded by enough material to protect it from most of the radiation it encounters during its millions and millions of years.. (good luck with that).. and then, it would have to survive the heat of entry into a planets atmosphere without being sterilized by the atmospheric compressive forces that cause the rock to get so hot it melts.
Could we "spread life thru the galaxy" if we wanted to? Not really.. We could launch a probe like Voyager and aim it at Proxima Centauri, but we'd have to wait about 80,000 years for it to get there, and whatever life we put on the probe would have to be well protected by several feet of dense (and very heavy), shielding to protect that life from radiation.
You can think of the radiation in space as being in three different categories... Low earth orbit, solar system levels, and interstellar levels.
Low earth orbit isn't so bad.. the guys on the space station seem to do fine.
Solar system levels are a couple of magnitudes more severe, and there's nothing we can do about them. That's why we haven't sent humans to Mars yet.. our best propulsion systems aren't fast enough to get them there in a short enough time frame were they won't be killed by the interplanetary radiation during the long trip. But we're getting there.. we're developing faster rockets..
Interstellar radiation is an entirely different story.. Its the difference between a BB gun (solar system) and that big ass 6 barrel vulcan canon on the A10 warthog attack plane.
Humans would simply not survive, and I don't think there's any life form on our planet that would survive for very long either, especially not the tens of thousands of years it would take to make the trip.
Concerning the space probe contamination issue for the machines we send to mars, even if they were packed with bacteria, and even if we found something that could survive, they would never leave our solar system. Probes sent to mars simply do not have the escape velocity needed to leave our Sun's gravitational influence. Even the Voyager probes didn't have enough velocity when launched. The Voyager probes had to use Jupiter to "slingshot" themselves to higher speeds..
So, spreading life thru the galaxy with our space probes? That's a big fat NOPE..
NASA is concerned because even DEAD bacteria can interfere with the sensitive instruments.. They're not worried about our galaxy.. We're not even capable of leaving our solar system at this point let alone worried that some extremophile is going to survive on a flimsy tinfoil probe.
Here, I just looked this up for you.. Kind of interesting.. The most robust extremophile on Earth that we know of is called "Conan the Bacterium" (ROFLMAO).. I guess some scientists do have a sense of humor.. If you put it on Mars, it would need 33 feet of Mars soil covering it in order to survive for geological time frames. That's 33 feet of dense shielding to protect it.. because Mars is bathed in radiation.
But even if it was dead from hitching a ride on the space probe, it could still interfere with the sensors.
Radiation is what keeps humans from going anywhere.. well, that and energy.. but mostly radiation. We need to develop fusion reactors and high temperature super conductors.. If we can create these two things, then we might (MIGHT!) be capable of developing a space craft shield that mimics the Earth's magnetic field that protects us squishy humans from the nasty stuff. And that craft better have a backup unit because if the first one fails, the squishy humans inside die.
All life on earth is carbon based.. from humans to simple bacteria.. when radiation hits us, it strips electrons loose from the atomic nucleus (the protons and neutrons at the center), which then changes the charge of those atoms, which then changes how they connect to other atoms to form molecular chemical bonds, which then causes those chemical bonds to break apart.. IE: your DNA gets destroyed.. and all life on Earth is based on Carbon and DNA.
In fact, it is most likely that all life in the universe (there are trillions and trillions of galaxies within the universe) is most likely carbon based.. Maybe not DNA, but most likely carbon. Why is that? Its because of the way carbon bonds form between themselves and with other elements. Carbon is the most versatile element on the periodic table.. and thus, all life forms from it.
"of less concern, is that such a bacteria could possibly multiply on the planet. Theoretically it might be possible."
You could have saved yourself a lot of trouble and admitted Bobs question was not so absurd at all. You agree with it right there.
Maybe youd be a more constructive poster if you werent so focused on proving others wrong.
Lets stop wasting everyones time and bury this subject.

That does not constitute "spreading life thru the galaxy with our space probes" Not even remotely close by any means or measure.
Bob does not understand the difference between our solar system and the galaxy and only a really REALLY ignorant person would postulate any such argument that NASA is concerned with contaminating the Galaxy.
Believe me, NASA wishes they could...

The solar system is part of the larger entity of the galaxy. If you spread something in the solar system, youre spreading it in the galaxy. Im pretty sure bob DOES know the difference between the two, and its obvious youre pursuing a semantics argument.
And lets not forget he posed it as a question, "is it possible?"
Thank you for all the astronomy knowledge youve shared with the group. I certainly learned a few things (besides the amazing amount of time some people, myself included, are willing to waste on internet pissing contests).

READ MY LIPS:
We are not "spreading life thru the galaxy with our space probes".. That's not even possible at this point in our civilization.
It is apparent that the concepts and science involved in this discussion are beyond your understanding. Just because we are part of our galaxy, it does not mean we can influence anything outside our own solar system.. even if we tried. Even if NASA wanted to, they couldn't "spread life thru our galaxy with our space probes".
The distances involved are so vast your tiny little monkey brain isn't capable of comprehending them beyond some very large and silly numbers on a piece of paper.. Don't feel bad, my tiny little monkey brain has trouble with it too.
Yes, but after berating him for such a stupid question because it shows a total lack of comprehension on the subject, he then went on to argue that he was right all along.. and you joined that path of stupidity. Neither of you has a clue of what you're discussing. Far more alarming than your ignorance, because we are all ignorant of certain things, is your lack of ability to acknowledge your own ignorance. That lack of ability, or lack of willingness, is dangerous to your health and wellness, and it has most likely caused severe problems in your life.
A much better way to go about things is to admit your ignorance, then start studying the subject and bash that ignorance into the ground, run it over with a garbage truck, then back up and run it over again.....
The first step in getting rid of ignorance is to get rid of beliefs.
You're welcome, and I sincerely hope I have expanded your knowledge, whatever it was when we started. I'm more than happy to talk astronomy anytime.

That's a very good point.. but there is also a very good reason for it..
Elon Musk isn't subject to the pitfalls of tax payer ignorance or stupidity. If he crashes a rocket, public opinion means almost nothing. When NASA crashes a rocket, entire committees are formed and demand answers and seek someone to blame.
Also, while Musk has done some really cool things, lets see how well he does trying to land on another planet without NASA data..
When we compare, we must compare apples to apples.
