Has ten more moons, for a new total of seventy nine. I’m old enough to remember when there were only four.

JWST
We expected this yesterday, but here it is:
Following an Independent Review Board report on the James Webb Space Telescope project, NASA has announced a further delay to the telescope’s anticipated launch. Coming just three months after a year-long delay to 2020, NASA now says the telescope will not be ready to launch until 2021 at the earliest and that the project will breach its $8.8 billion USD cost cap.
The cited mismanagement at NG and NASA is just staggering. The new overrun is about the amount that it was supposed to cost, in total, originally. What a programmatic disaster.
I hereby rename JWST the Jeebus Wept Sunkcost Trap

Here’s the story from Jeff Foust.

This can never be allowed to happen again…. The good news is that it does not have to. On Orbit Assembly transcends the limitations around building a big telescope on the ground, shaking the hell out of it for 10 minutes, then deploying it autonomously without fail. https://t.co/lPmq4UgdVi

[Thursday-morning update]
Here‘s Marina Koren’s take:
A wiring error caused workers to apply too much voltage to the spacecraft’s pressure transducers, severely damaging them. And during an acoustics test, which examines whether hardware can survive the loud sounds of launch, the fasteners designed to hold the sun shield together came loose. The incident scattered 70 bolts, and engineers scrambled to find them. They’re still looking for a few. “We’re really close to finding every one of the pieces,” Zerbuchen said.
These three errors alone resulted in a schedule delay of about 1.5 years and $600 million, Young said.
I think that’s about Northrop Grumman’s annual net income. If I were NASA, I’d tell them that if they ever want another NASA contract, they’ll eat it themselves.

Alex Witze has more, over at Nature.
Complex Organic Chemistry
For people interested in non-terrestrial life, this should be a higher priority than Europa. It’s farther away, but a much more benign radiation environment.
Methane On Mars
Tanya Harrison has the story. As always, a reminder that people who want to settle Mars should hope that we don’t find life there.
Mars Rover Rovings
For those interested, Bob Zimmerman seems to have this beat covered.
Interested In Water On Mars?
Then this post by Bob Zimmerman is for you.
Space Regulation
With the Legal Subcommittee meeting of COPUOUS in Vienna a little over a week away (I’ll be attending this year), Laura Montgomery has a new paper out, and Christopher Johnson has some thoughts, too.
JWST And The Media
Thoughts from Bob Zimmerman on the latest overrun and schedule slip, and the shoddy reporting of it.
The JWST
It’s delayed again, and over budget. Again.
I would have canceled it years ago. It was a mistaken concept from the get go. For what we’ve spent on this program, we could have had orbital servicing capability, obviating the need for the origami, and even allowing servicing in situ.
The Deep Space Network
Shannon Stirone has a nice essay on the history and state of affairs, and Congress’s skewed space-budget priorities.
I think the future of deep-space comm will be lasers, and it may be provided commercially.
