Cool beans, subby, cool beans.

Bookmarked. Now I have to set alarms so I can watch the status IRT.

The descriptions of each stage if deployment en route to l2 was pretty helpful. It's already lost a bunch of speed from yesterday, and I wondered why. It answered, and it's gravity.

no1curr: Make it do a barrel roll


Meme I know, but spin stabalization (and heat regulwtion) means many space craft do continuous barrel rolls. I'm not sure if Webb is one of them during the transit phase. Definitely not as it nears operations.

Not quite. A barrel roll isn't a simple rotation around one axis.

You found a better illustration


So, when is first light?

It will need to slow almost all the way to zero when it gets to station. Not sure how or even if that speed will be reported out. It will still be orbiting LS but at basically zero dv/dt with respect to earth.
 
2021-12-26 9:39:49 PM  
I like that they have a little moon to illustrate Webb's distance away relative to the Moon's orbit.

I wonder if they will find anything else out there at the L2 point when they get there. Maybe it does not have any cameras that can look at the local environment.

That site is amazing, gets me all excited

Observatories on earth can detect what is there, and at the L4 and L5 points (which do have some rocks there).  It isn't stable at L2 and most everything there eventually leaves.  There have been a few other satellites that have parked there for a while: WMAP 2001-2010 Herschel 2009-2013, Planck 2009-2013, Change'-2 2011-2012, Gaia 2014-present. Also brief L2 'flybys' by ISEE 3, Hiten, Wind, Genesis, ARTEMIS P2, Spektr RG

as far as we know there is nothing at L3 (opposite the sun from earth)

IgG4: It will need to slow almost all the way to zero when it gets to station. Not sure how or even if that speed will be reported out. It will still be orbiting LS but at basically zero dv/dt with respect to earth.


It is scheduled for a 122ms burn when it reaches L2 to put it in a Halo orbit and then begin the process of cooling down, and calibrating the sensors

it should remain there for 10 years, and even has the ability to be refueled if they decide to extend the mission further

Just think, a Scientist working with Webb could not even be born yet, and that is amazing

I'm assuming the figures are projected from the craft's current trajectory, in which case it should match JPL Horizon's predictions of a geocentric velocity of about 193 m/sec on Jan 23 at 15:01.

Watching paint dry would be more interesting than waiting to hit f5

I'm getting a Capricorn One vibe.

I'm sure it's perfectly fine.  But I still can't shake that nagging feeling that something is wrong, or it is known that something will go wrong soon, and they're just going through the motions because they have to.  Yeah, I know, but it's been such a long time waiting with delay after delay (to the point where Randall Munro did an XKCD comic about it), that I just have a sense of foreboding.

Well, at least we won't have black helicopters chasing O. J. Simpson in the desert this time.

Almost. Not living in Myanmar, Liberia or the United States, I switched the units from miles to kilometres. After refreshing, it reverts to miles.

I was just texting with my 19 year old son about Webb and made an offhand comment about "hope it doesn't turn into a Hubble needs glasses situation"

He had no idea what I was talking about.

It will display that once more equipment is deployed. I forget which step but it's sooner than later.

Seriously, do we have any idea at all what if anything is at L3?

It's not going to work. Just before launch, the techs forgot to wind it.

There are satellites watching the sun which also looked at that region of space. There's noting planet-sized at L3 or else it would have shown up. Can't rule out small rocks or UFOs, but it's one of the unstable points so there's not likely to be anything.

Space is at l3

Whats in that space depends on the moment in time you look at it

In a sense.  The 'Cold Side' REALLY has to stay as cold as possible.  There won't be anything to report in those fields until the sun shield is deployed and they can start cooling down the instrument side.  In the meantime, all they can do is make damn sure the instruments never get exposed to the direct sun or it's Game Over.

The sunshield will do an amazing job. Totally passive, yet the anti-Sun side will maintain a temp of less than -230C. In fact, I suspect they had to work out the effects of the shield acting as a small solar sail.

Other than second Earth.

And it's becoming increasingly clear that we're the Earth with the evil beard.

Sweet!
Bookmarked.

Hubby works at Northrop Grumman so we got to see it in person pre-launch. Our teens, who are impressed by basically nothing, actually enjoyed it and are excited to see the first images.
