Decades of tension, debate, and determination have led to
this moment, as the James Webb Space Telescope begins its
million-mile journey into deep space.

What is that one supposed to do besides litter space with more
junk? :/ What is the "debate", and why "tension"?

It won't be in orbit around the earth, so no pollution of orbit space. It's kind of the successor of the Hubble space telescope.
It will see things never seen before.
It has cost about 10 Billion so far. 10 times more than estimated. Because of it's place in space it can't be repaired once launched. Because of it's size it's folded up inside the launch rocket, and needs to
be deployed after launch. So a lot can go wrong, and for that price, and the possible return in science data is so high, people are very anxious/exited about the launch, and deployement fase...

Bye, Wilfred.
Launch was a success! It's now in its preliminary orbit around the
earth... Bye, Wilfred.
When are the first results (data, images) supposed to occur?
Btw: It's now already way past (@48km's) the orbit of geostationairy satelites (which is about 35,7 km above the earths surface).

It's now, a day after launch, almost 240 km from earth.
That's not even half way the distance to the moon. And
about 16,5% of the distance to it's destination point in
space. It will take about 29 days [..]
If you're interested you can follow it's journey..

The physics/math/mechanics to make all the happen seems
astonishing.

That's a nice page. It kinda reminds me of the days watching
modem uploads/downloads. :/
But what do the gaps between day 2-3, 9-10, 11-12, 14-15, 26-29
represent?
At about 1.5-2mi/sec hope there isn't any teeny tiny debri that
can render it useless.
FYI, it hasn't made it to ASTRONOMY on 396/45 yet.
That's odd, because he is connected to that area on my system, so he got it direct. (And my outbound is empty)

That should have been: 240K km! :/

That also took days? ;-)

There's always that tiny, tiny, tiny risk. But it's
already well beyond the "commercial" earth orbits, so
that debri wouldn't be human made...

Maybe the odd loose screw or bolt that has sprung loose from
the myriad of launches over the decades will cross paths with a
new mission.
Not that far from earth where the JWST now is (half way the distance to the moon). There is hardly anything there, compared to the low earth orbits.

I'm not getting a connection at 396/45 in the last couple days
either. :(
When was the last time you connected?

But then, maybe the gravity of nearby planets or
moons could take care of such problems.

How can it be 25% of it's distance at day 3, when it only enters L2 in it's 29th day?
It will take about 29 days to get there. It will take so long to get there, because there is no propulsion anymore (except for some short
burns for course corrections). It's in the balistic fase on it's path
to it's destination, and because of the gravitational pull of the
earth it's constantly slowing down slightly. Its speed now is about
1.7 km/s relative to earth, while during the launch fase it topped at about 10 km/s...
... compared to the low earth orbits.
No Kidding.. I just read THIS in the news:
"China RAGES at Elon Musk after space station near miss with
Starlink satellite
"China complained to UN in a diplomatic note, its space
station had to take evasive action to avoid collision with
satellites launched by the billionaire's Starlink program.
(SCMP)
"Satellites from Starlink Internet Services, had two "close
encounters" with the Chinese space station, according to a
document submitted to the UN Space Agency.
"For safety reasons, the China Space Station implemented
preventive collision avoidance control," China said in the
document.
This is only going to get worse as things get crowded up there.
I'm not getting a connection at 396/45 in the last couple days

I see some failed connects in my log, but most of them go ok...
But what do the gaps between day 2-3, 9-10, 11-12, 14-15, 26-29
represent?
I don't know, I was wondering about that too. And it doesn't seem to correlate too well to the deployment steps...
... I've talked to Marc, and he has
(remotely) reset his system, and it seems to be ok now...

Yes. All systems are a go now. Thx.

Something stopped working right here too a few hours later (and
now a few minutes ago) when I made my next poll.

Bye, Wilfred.

He fixed that via remote too?
Amazing! Anyway.. a poll responded this time. Thx.
He fixed that via remote too?
... By calling someone at the remote site and have them
reset the cable modem? (I don't know, just speculating...
;-))
That would only be possible with an alternative internet
connection to the remote site. Otherwise it could be
amazing indeed. ;)
Silicone-based entities are so overrated. The carbon-based
units rule!
