Jwst launches in less than 3 hours

Something is moving out there that wasn't there before launch and is right where it is said to be. Way more evidence than what you have - Your evidence being nothing.

Where's your evidence for the virtual telescope being a hoax? Yep, just what I thought, you have none.

Let's return to the virtual pictures of the JWST moving to L2! The JWST is moving pretty fast in its orbit around Earth and must slow down to same speed as L2. But the JWST has no means (rockets/fuel/energy) to do it. Thus, the whole thing - JWST, virtual telescopes - is a hoax. 

Your lack of correct information, combined with the confidence with which you share it, is truly remarkable!

Just listen to the people behind the virtual telescope. Would you buy a second hand space telescope from  them?

Yes, I would. At least they realize and show evidence that telescopes are infinitely better than your old eyes looking out your window.

Let's see your evidence that the virtual telescope is a hoax.

Do some research into orbital insertion. You are woefully ignorant as to the physics applied by the much more knowledgeable people than you who calculate, engineer, and execute such things.

Just because you don’t know how something works doesn’t mean it doesn’t work. Stick to your ‘danger at sea’ work.

Heiwa is a danger at sea. Tell us about the time you tested your 'bow visor impossible to break' theory with a bunch of unwitting sleeping crewman aboard, Heiwa....

No wonder you lost your job.

From https://webb.nasa.gov/content/webbLaunch/whereIsWebb.html I Iearn:

“Telescope deployment is complete. Webb is now orbiting L2. Ongoing cool down and eventual instrument turn-on, testing and calibration occur. Telescope mirror alignment and calibration also begin as temperatures fall within range and instruments are enabled.
The telescope and scientific instruments started to cool rapidly in the shade of the sun shield once it was deployed, but it will take several weeks for them to cool all the way down to stable operational temperatures. This cool down will be carefully controlled with strategically-placed electric heater strips. The remaining five months of commissioning will  be all about aligning the optics and calibrating the scientific instruments. “

So after cool down using electric heater strips there is another five months of commissioning before we can see anything. What a joke!

No one cares what you think Heiwa. Email NASA and tell them it's a joke then. I bet you won't get a reply because the only joke is you

My refrigerator doesn't use heater strips to produce ice cubes. I have my doubts about ESA/NASA and their JWST using heater strips to cool down in vacuum space.

Here is an example of how it works in operation


I know you're old and senile but even this concept shouldn't be above you

The ADIR, which swings away from the backside of the telescope like a trap door on hinges, is connected to the instruments via flexible straps made of high-purity aluminum foil. The radiator draws heat out of the instruments and dumps it overboard to the extreme cold background of deep space.

To be clear - there is no 'active heating' lol. It's deflecting heat away from the telescope... Can your brain decipher the concept now or are you beyond help

No, I don't understand the concept.
Where is the heater strip and where is the telescope? And what is being cooled?

No, I don't understand the concept.

I see. Well, good luck with the rest of your life

Well it says there is Shifty, and to be honest if you have very expensive and finely tuned apparatus you probably want to go from 54c to -211c in a controlled manner to limit shrinkage and stress.

Controlling heat loss is not the same as heating something up. The temperatures trend will always be going down

You can still use active heating to control heat loss. These things are not mutually exclusive.

Anything that is not 0 Kelvins has 'heat'

If the system (in this case the James Webb Telescope) is always in a state of losing heat, then there is no 'heating'. You can apply energy (heat) to the system but if the energy produced is insufficient to raise the temperature than it can't be 'heating' the system.

I see what you mean but my mind when saying 'active heating' was in regards to Heiwas insinuation that the telescope cools down by heat. There are also some nifty tricks the telescope is doing to reduce heat in a passive manner (like the animated gif I posted).

According to https://webb.nasa.gov/content/webbLaunch/whereIsWebb.html?units=metric it is freezing cold at the L2 point, except when you are exposed to the Sun far away, which you are not at the L2 point, which is in the shade of the Earth. So why do you need to cool down anything. Maybe ESA/NASA means heating up?  The Universe is a pretty cold place.

A halo orbit around the L2 point is not the same as sitting at the L2 point.

You keep stating that the JWST is in Earth's shadow at L2 and you are wrong.  The telescope will be kept out of Earth's shadow to maintain thermal stability. Go read some literature, stop making up bullshit, and claiming NASA/ESA are a joke.

Not sure why Heiwa bothered with this thread. He can't keep up with his own trolling and keeps tripping over his own BS

He probably doesn't have to admit he's wrong because he knows he's just talking shit. He wants us to believe that we believe he believes what he's saying lol. Except it's pretty clear he's just become a low effort troll

He had his 'challenge' BS trolling stories worked out but this, it's clear he never researched it well enough to come up with and stick to a story. He should have stayed in that thread of Mikes he claimed.

It seems the Moon orbits the Earth and the Earth orbits the Sun and the JWST flies around in space in an impossible trajectory orbiting nothing.
It seems we agree that the Moon doesn't orbit the Sun (but the Earth). I can see that from my window.

What makes it impossible? Do tell us. You're about 250 years behind the times in regard to orbital mechanics.

MECHANICS OF HALO SATELLITES
A. Motion in the Vicinity of the Translunar Libration Point
As was shown by Lagrange in 1772, there are five points in the earth-moon gravitational field with the interesting property that if a satellite were placed at one of them with the proper velocity, it would be in equilibrium because the gravitational accelerations acting on the satellite would be counterbalanced by its centripetal acceleration (i.e., accelerations are balanced in the rotating reference frame). These 11libration points 11 are all located in the moon's orbital plane, and their general configuration is depicted in Figure 2. This paper will be primarily concerned with the translunar libration point L 2



The third-order solution for the nominal path in the vicinity of L 2 is given in Appendix B. Traces of this solution for a one-year period are showJl in Figures 3 and 4. Because the period of the oscillatory motion in the moon's orbital plane is 14.65 days, while the out-of-plane period is 15. 23 days, the yz-projection of the nominal path is a Lissajous curve.

Show us your calculations versus those contained within the document. I'm sure your calculations make it impossible.

Just because you don't know how something works doesn't mean that someone else hasn't figured it out.

I am not against Lagrange points. I just suggest that a space craft ejected from Earth only orbits Earth and nothing else and that a return to Earth by such a space craft (re-entry) is not possible. You cannot orbit Earth and then start orbiting something else or land somewhere, i.e. travel around in space between planets or moons in space. Including Lagrange points. It is just NASA fantasies to enable asstronuts on the Moon.

I am not bored at all. I look out of my windows and watch the Mediterranean Sea below and the objects in the sky above and the horizon in between. That the JWST elliptically orbits Earth governed by gravity forces, I can see, but it in a fixed plane relative Earth, i.e. it doesn't wobble around in its trajectory ... around Earth or L2 as suggested by others. Does ESA/NASA really know what an "orbit" is? An orbit is the curved path of a celestial object or spacecraft round a star, planet, or moon in a fixed plane, and with a periodic, elliptical revolution.
