Comet lander

[bohemian]

the space probe sent to the comet, and which landed on said comet, has run out of power! The battery has run out.

It reminded me of this song by the great Ivor Cutler:

In a wonderful statement reminiscent of the Monty Python parrot sketch, one of the scientists said:

Astrophysicist Elizabeth Pearson: "Philae is not dead it's just sleeping"

Isn't that funny about it running out of power. I was watching a special on pbs about it and did you know when they sent that off it affected the earth's time by something like 1/1000 of a second? Which is nothing I realize but no one knows what else that could affect. Man just doesn't realize what they are messing with

Mandy, I don't believe sending a spacecraft affects earth's time in any sense. With the amount of planes that take off daily time would be crazy!

The earth rotates at a speed of 465 meters per second, with a mass of 6x10^{^24} kilograms.

 

The Rosetta mission left earth at a speed in the range of 10 meters per second, with a mass of 3000 kilograms.

 

Any theoretical impact that the Rosetta mission launch had on the rotation of the earth (over ten years ago) has long since been negated by the nearly 100,000 kilograms of meteors hitting the earth per day, at a speed of around 50,000 meters per second.

 

In other words, the Rosetta mission, at the absolute maximum, assuming perfect conditions and perfectly optimal engines, launching exactly on the equator, etc, the highest possible effect on earth's rotation would be the same as the entire number of meteors hitting the earth every half second.

[Mandyr]

I'll look it up and find an article to post but it had to do with how far out they had to send the Rosetta to meet the comet. So they had to use the gravitational pull or something like that to basically throw it out in the universe. Trust me my husband and I couldn't believe it either. I'll research it

They used the same gravitational pull that keeps the space shuttle, ISS, thousands of satellites, moon, planets, and even the comets themselves in orbit. Even if the effect of the launcher was tiny, that effect would be many millions of times larger than the effect of the orbiter being pulled into earth's gravity to speed up.

 

Thinking about it more, they may have been speaking of the effect of relativity, where the extremely high speed of the spacecraft caused the clock to go slightly out of sync with those on earth. This is a well-known and well-studied effect, and it exists solely within the spacecraft. It has absolutely no effect on the earth whatsoever, it's simply the result of the way space itself is made, and what happens when traveling through it at high speeds.

And it would be noticeable only if traveling at a speed near the speed of light... Far, far, far, far, larger than the spacecraft (or any other men made object) maximum speed

Ok well I've looked and looked and I can't find anything to support my claim. So I apologize. (darn pbs) but it's called gravity assist or slingshot but I couldn't find anything that said how it effects the earth. So I don't know where pbs got that. Guess I learned my lesson. No claims without backup. Got it. Sorry again.

You're very welcome, Mandy.

 

And no problem, we like to discuss everything.

You probably heard correctly ..

There are "A" level physics formulas that calculate all the theoretical impacts of this

We think of the earth being static but it is constantly changing ... We are receiving probably over a 100 tons of. Cosmic dust a day..

But this process has been going on for millions of years .. We have lost materials due to impacts and gained material due to impacts...

Sure glad I am not in charge of keeping this earth on time ..)

[happy servant]

I'm sure there are lots of things in this world that change our perception of how time passes. Time is really different depending on who's observing the events pass by. Wouldn't it make sense to speed up time in the time of the end so that you can be distracted not feeling you have enough time?

"The ESA's Rosetta spacecraft made several detections of the amino acid glycine, used by living organisms to make proteins, in the cloud of gas and dust surrounding the comet, scientists said."

 

I found this article interesting because in many ways it backs up entirely what Jehovah said he did on earth - making Adam from the dust would have included all the building blocks necessary to make an organism.  (Then it just needed Jehovah to blow the breath of life and he became a living organism.)  I would not expect the universe to be a sterile place, but it is constantly in flux, and in varying degrees of development - rearranging matter and particles into other forms.  If Jehovah wants life on any said planet, then it will happen, because he has set the bits needed for this to happen in motion.  He started here on earth, and we will be blown away with what we will learn about Jehovah's purpose for the rest of the universe, hey?

[Shawnster]

Hmm.  Lucy,  that is an interesting interpretation I never thought of... 

[hatcheckgirl]

Interesting as in "weird"?

I guess I just enjoy learning what scientists discover, but I don't necessarily follow their interpretation.  As for the future and life on other planets, we'll find out eventually - Jehovah willing we are there.

Even if they found microorganisms, plants or animals in other planets that would not contradict the Scriptures. Only intelligent life would.
