OK... talk about being played... Now, NASA has landed on an asteroid and took a sample .... in six seconds of a touch and go type event..

Firstly.. do they think that there is rocks, pebbles and debris... just sticking to the sides of this rock? It's 500 meters long... We have already been told that gravity is by mass... Do rocks stick to the side of a cliff? Nope.... Yet they would have us believe that this large rock is covered with loose material.. clinging to it...

This is the only material that they would be able to take.. If it's a rock.. and the space craft does a touch and go.. staying on the surface for six seconds.... there is no time to drill a core sample... not even a small hole..

But, they are going to tell you ... in 2023...a long enough period of time.. from today... to have you swallow the nonsense that they have a certain quantity of material.. from a large rock in space.

Yes, in the movies.. Bruce Willis lands and stands on an asteroid... where is the gravity coming from.. Even on the moon which is 1/6 the size of the earth.. men where portrayed as jumping much higher than on earth..

Now.. think of an object that is not even a kilometer long.. and you want to "land" on it? Sorry.. but you cannot do that.. You would just bounce off... just like the side of an airplane...
And, rocks, pebbles, sand and dust... is not going to stick to it by some miraculous force.

People, this is how gullible and naive the people of the world have become.. They believe it because they are told.. that's it..

And.. anyone who, like me, calls "horse pucky" is going to be ridiculed...

The whole thing is a joke.. a fraud.. a story... Oh.. it would make a good movie.. yep... been done already... but.. it is as far from reality as you can get... but.. people accept it like it's solid truth...

They say they blast it first with nitrogen to dislodge a sample.

"When the arm made contact with the asteroid surface for about 15 seconds, a blast of nitrogen gas dislodged a small, carbon-rich sample of pebbles and soil, which were collected by the sampler head and then stowed. If it turns out that insufficient material is recovered, the spacecraft will try again at a different area in January 2021. Otherwise, the current sample will be placed in a return capsule and in March 2021, OSIRIS-REx will depart from Bennu and begin its journey back to Earth."

Like I said... "pebbles and soil" do not stick to the side of objects 500 meters long... even in zero gravity areas....
Anything that was broken "loose" would simply float away...

Set your stop watch for 15 seconds.. What is a blast of nitrogen gas going to do in an environment that can be thousands of degrees hot.. to hundreds of degrees colder than the earth.

But no.... NASA is going to fly up there and with a puff of N2.... create debris... OK.. sure..

That's like shooting a Red Ryder BB gun at a bullet proof window in a Hummer...

The difference between rocks on an asteroid and rocks on a cliff or the side of a plane is that there are other forces in operation in those instances.

On the cliff there is the gravity of the Earth pulling downwards and on the plane there is both that gravity and the friction of the air acting against you.

On an asteroid the minuscule gravity of the objects will be the biggest force around.

As to how a lander can "land" on an asteroid, yes, bouncing off is a real concern. A term that conjures a clearer mental image would have been "docking", the lander would have to match velocities with the asteroid and gently touch down.

I have two separate thoughts about news, #1 is it possible?, #2 is it true? I don’t even merge the two anymore like most people do. The media has been caught in so many lies that they don’t deserve the benefit of the doubt even if a story is possible.

If a rock on earth weighed 60 lbs.. on the moon it would weigh 10... on the asteroid... it would not weigh enough to hold it on the surface.. It's mass would be negligible.

"The activity needed to launch these particles is “about the same energy you need to break a cracker,”

Well, electrostatic forces might also be present along with the micro gravity. It's interesting.

Nature surprises over and over.

Here is an interesting look inside the surprises on this asteroid.

This is the first image of an asteroid as it chucks debris off into space



Visit your local big city museum of science. Spend a few hours. Better yet, if it's large with many demonstrations, get a membership and visit many times. You'll be surprised by some stuff, how things work.

If you want to drive deeper on the gravity stuff here's a science news report. "The mass of that asteroid: a respectable 73 billion kilograms....". Some interesting, involved dynamics.

Really interesting stuff:
Weird, wild gravity of asteroid Bennu

So, this asteroid is one of the oldest rocks of the universe.. yet it continually ejects pieces of itself into space.. and .... miraculously.. still exists... Really? How big was it then when it started? And... further to that.. if it was much bigger before.. it would then have the mass that planet sized objects have and would not eject debris...

So.. it is an oxymoron... It could not have been ejecting particles for millions of years and still exist..Or.. it was really big to start and nothing would have escaped it's gravity...

Nice try though.

Sounds legit....... weird gravity... fixes everything..

The only thing I believe from NASA is that it is spelt N..... A..... S..... A.

After that... it's anyone's guess as to what is truth and what is lies.

Where else are the particles going to go?

It's the biggest thing in it's area. The smaller particles are going to be collected up by it.

LOL... is that why all the dog hair sticks to me?

Just because it's the only rock in the area.. doesn't give it some magical attraction...

Where else are they going to go? Really?.... They will just float away...

The mass of a grain of sand... that is 0.006g on earth.. would be 0.001 on the moon...

On that rock... it would be insignificant... The grain of sand is not going to stick to it just because it's the only solid object in the neighborhood....

Gravity is either there.. or it's not.. It doesn't all of a sudden become more attractive.. because it's the only thing around...

Don't you understand?

It's not a magical attraction, it's just gravity.

There is no other force nearby. Things don't just move, they need a force put upon them.

It will stick to it precisely because it's the only solid object in the area.

While the force of gravity may be miniscule on the asteroid it is still the only force around and given time it will attract space debris to itself. Ever. So. Slowly.

It is almost axiomatic that the less one knows about a topic the more that one is absolutely certain of their claims.

Just because an object is the only object in the area.. does not increase the gravitational pull....

The force is the same.. it never changes.. It is not dependent on other objects being there or not being there..

We are just conditioned to believe that if Bruce Willis lands on an asteroid in space.. that he will be able to walk around on it..

In actual fact.. one little flick of his toes and he would float away.. If he wasn't tied to it.. he wouldn't be able to use enough force to drill a hole..

I never said it increased the gravitational pull, just that it was literally the only force in the area.

Without any friction the force pull the particles back together.

That's because movies are giving people ideas that don't exist in the real world... You see it so much on the TV or in the theater.. you accept it when others tell you similar things...

I guess the satellites and the ISS should have all kinds of little space pebbles and dirt sticking to it. Guess that's why they have to go wash the windows..
