Did you notice that for us "Northern-Hemispherers" this moon is upside down? :mrgreen:

Photography fact: moon surface is in sunlight, so should be exposed the same as terrestrial landscape in sunlight. Save that the moon's material is very dark (3 stops or only 12.5% of terrestrial objects' mean albedo) – roughly like coal.
Doesn't seem that way, uh?

Another: looking at a portrait we get unconscious cues about the distance to the person from the relative sizes of nose/eyes/ears, from the same perspective "distortions" (in fact just geometry) at work in the moon videos. So if you want the spectator to feel (sometimes uncomfortably) "near" the subject, part of the action, use a wide angle; normal, socially acceptable distance, use a normal lens; want that sophisticated model seem far away, unapproachable, go for telephoto. Even if the face is the same size in the final print.

Regarding the upside down moon, leave it to the damn Kiwis to damage a perfectly good natural satellite.
Seriously though I hope to visit the southern hemisphere if only to be utterly confused by the night sky.

APOD wrote: It looks like a big space diamond -- but with craters. It's 162173 Ryugu (Dragon's Castle), and Japan's robotic Hayabusa2 mission is now arriving at this near-Earth asteroid. Ambitious Hayabusa2 is carrying an armada of separable probes, including two impactors, four small close-proximity hoverers, three small surface hoppers, and the Mobile Asteroid Surface Scout (MASCOT) which will land, study, and move around on Ryugu's surface. Most of these are equipped with cameras. Moreover, Hayabusa2 itself is scheduled to collect surface samples and return these samples to Earth for a detailed analysis near the end of 2020. Previously, what was known about asteroid Ryugu was its orbit, that it spans about one kilometer, and that it has a dark surface that reflects unusual colors. Studying Ryugu could tell humanity not only about Ryugu's surface and interior, but about what materials were available in the early Solar System for the development of life. Pictured, a series of approach images shows features suggestive of large boulders and craters.

NASA announced on Wednesday that the James Webb Space Telescope, once scheduled to be launched into orbit around the sun this fall, will take three more years and another billion dollars to complete. A report delivered to NASA by an independent review board estimated that the cost of the troubled Webb telescope would now be $9.66 billion, and that it would not be ready to launch until March 30, 2021.

At some point asking wtf is appropriate. It is impossibly complex. I say just launch the fucker and if it doesn't happen, then everybody on the team is fired for cause.

Damnit.

It does not instill confidence when they are both late and asking for another cool Billion.

Fuck.

Update:
Hell Yes, Japan’s Hayabusa2 Spacecraft Has Officially Entered Orbit Around the Ryugu Asteroid

After nearly four years of traveling through space, the Hayabusa2 spacecraft has successfully rendezvoused with the Ryugu asteroid, the Japan Aerospace Exploration Agency confirmed Wednesday. Let the next stage of this historic sampling-and-return mission begin!

Earlier today, mission controllers at JAXA triggered Hayabusa2’s chemical propulsion thrusters, bringing the spacecraft into orbit around Ryugu, an asteroid that’s just shy of one kilometer (0.6 miles) wide. Confirmation of the rendezvous was made at 9:35 am Japan Standard Time (JST). JAXA says Hayabusa2's thrusters worked normally, and that the spacecraft is maintaining a constant distance from Ryugu.

“From this point, we are planning to conduct exploratory activities in the vicinity of the asteroid, including scientific observation of asteroid Ryugu and surveying the asteroid for sample collection,” explained JAXA in a press release.

That's sad. Still, I'd rather have one in 3 years that works than an expensive piece of space junk now.

I agree that the complexity is a big worry. Too many things have to go exactly right.

At this point it's approaching the total cost of LHC and I am not sure James Webb Space Telescope is more complex than that. It's can't just be complexity, quite a bit of incompetence has to be going on either in execution or planning stages.

Unlike the LHC though, they only have one chance to get it right. If a part of the LHC is busted, it can be replaced or repaired. Not so with this telescope (unlike the Hubble which was (is) in an orbit where it could be serviced).

That's true but that alone doesn't explain the run-away budget and production schedule.
