Just a quick note to point people to a delightful overview of the James Webb Space Telescope (JWST) done as a flash animation, via Bad Astronomy. The JWST is the successor to the Hubble Space Telescope (HST), and will be able to look back further into the history of the universe.
Minor bit of trivia: the early information on the JWST which was available helped me to come up with the design idea for the ‘Advanced Survey Array’ in Communion of Dreams. I never really get into a description of the ASA, but I had to think through for myself how the thing worked to use it consistently in the book.

As you likely know, the Space Shuttle program is coming to an end, and each of the shuttles are on their final launch schedules. Take a few minutes and watch this amazing time-lapse vid:
The action starts in the hangar-like Orbiter Processing Facility at NASA’s Kennedy Space Center, where Discovery has been outfitted for its STS-131 mission. The vehicle is then towed to the 525-foot-high Vehicle Assembly Building, hoisted into a vertical position and lowered onto its external fuel tank and twin solid rocket boosters. Then it’s off to the pad on the giant Mobile Launcher Platform, where the shuttle is encased in its protective Rotating Service Structure until just before launch on April 5, 2010.
Sometimes the things we do impress the hell out of me.

The Air Force launched a secretive space plane into orbit Thursday night from Cape Canaveral, Florida. And they’re not sure when it’s returning to Earth.
Perched atop an Atlas V rocket, the Air Force’s unmanned and reusable X-37B made its first flight after a decade in development shrouded in mystery; most of the mission goals remain unknown to the public.
The Air Force has fended off statements calling the X-37B a space weapon, or a space-based drone to be used for spying or delivering weapons from orbit. In a conference call with reporters, deputy undersecretary for the Air Force for space programs Gary Payton acknowledged much of the current mission is classified.
The X-37B looks like a miniature space shuttle, and evidently the design was based on that system. The much smaller size (about one quarter the size of the shuttle) does give some indications of the limitations of the missions it could be used on, and it seems to not be quipped for life support – but beyond that, not much is publicly known.
One particular reason I find this of interest is that in the ‘future history’ in which Communion of Dreams occurs, this is exactly the sort of secret tech which has been developed by joint US & Israeli efforts – a fleet of these sorts of unmanned vehicles forms the basis for a concerted effort to establish a colony on the Moon, which are then supplied with personnel by use of new full-size shuttles which have built using the same technology but equipped to handle human life support. One of the main characters of Communion of Dreams, Darnell Sidwell, is heavily involved in this effort, and his role is mentioned in CoD. In my future history, this whole development is about ten years ahead of what is indicated by the news of the X-37B launch. In fact, most of this story forms the background for the prequel to CoD which I have mentioned previously, titled St. Cybi’s Well.
But then, who knows how much of what we’re now finding out is the actual truth? I mean, the Atlas lift capability has been around since the Apollo days. The basic shuttle design goes back to the 1970s. Do you really think that they stopped improving the tech for military applications until just ten years ago?
Really?

I’m not big on Valentine’s Day. No, I’m not some kind of cold, unloving bastard. Quite the contrary – I resent the cynical manipulation by the greeting card and floral industries creating the expectation that men can only show their love on one special day each year. I love my wife and try to show it to her in many honest ways throughout the year.
But February 14th is memorable for me for another reason.
20 years ago on this day we received a picture – a perspective, if you will – which we had never seen before. That of Earth from the vantage of the Voyager 1 spacecraft – an image which has come to be known as the Pale Blue Dot. The book of the same name helped inspire and inform my writing of Communion of Dreams – a fact which can be seen in several passages, but which most readily comes to mind for me as this dream sequence:
The bridge was perhaps three meters wide, and arched slowly up in front of him, so that he couldn’t see the other end. It had walls of stone about a meter high, and periodically along those walls he could see small sculpted stone vases in which grew roses. Blue roses. He went over and peered into one of the buds, a clean blue light almost like a gas flame. The petals spread, until the flower was completely open.
Turning, he started to walk toward the rise in the center of the bridge. After a few dozen paces, he was almost halfway across the bridge, but he couldn’t see the other side. The fog seemed to rise up from the surface of the river, the bridge stretched off into a muzziness of grey. Then he noticed that the roses in a nearby vase were smaller, the light somehow more distant.
Another couple dozen paces and the end of the bridge where he had begun was almost out of sight. The roses had continued to shrink in size, and the light of each receded. It had grown darker, too, the sun had begun to shrink in size, as though retreating from him. He walked on. There was still no end in sight, just the bridge continuing into a growing dimness. The sun was smaller still, and had lost enough intensity that he could look straight at it without discomfort. The roses here were so small as to be hard to make out, the blue dot of light in each flower becoming pale. And he noticed that the walkway beneath his feet now felt spongy, like it was becoming insubstantial.
Tentatively taking a few more steps, at last he felt his foot sink into the bridge, and he started falling forward.
That’s from the end of Chapter Five, as the protagonist and his team of scientists are en route to Titan and are metaphorically crossing from the known to the unknown. Just as Voyager continues to do.
Happy Pale Blue Dot Day.

All Things Considered had a nice piece about this photograph and what led to it last Friday, which includes this nice bit from Carl Sagan:
Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.

I mentioned the other day that I would provide some further recollections about the Apollo 11 landing and Moon walk, but yesterday after all other coverage of the event that I read and heard, I wasn’t really sure what to add. You can find a brief description of how I experienced that historic “small step” at UTI, if you’re interested.
But last night, after thinking about the whole thing a considerable amount, I decided to pop open the new NetFlix disc that arrived in the mail yesterday. Another in The Invaders! series I wrote about in June. And on it was an episode titled “Moonshot“.
Well, of course I had to watch it.
And I was . . . rather amazed.
Oh, it was the typical formula for the show: something happens that seems to indicate alien involvement, and the star of the show hears about it and comes to the site to investigate. There he meets up with someone else who has suspicions about the aliens, and together they try and thwart whatever evil plot is being cooked up (sometimes successfully, more often not – this is a series in which the good guys win at best marginal victories).
But this was different. Not because of the formula, or acting or anything. But because of *when* it first aired: April 18, 1967.
What is significant about that date? Well, because it was just three months following the Apollo 1 disaster. And the episode is all about how the aliens are killing off the astronauts selected for the first manned Moon mission.
I’d bet the episode was already “in the can” by the time of the Apollo 1 tragedy. Maybe not. But either way, it is rather astonishing that they decided to run the episode so soon after that event. Most people now don’t remember, or don’t appreciate, the impact that Apollo 1 had – it has been subsumed into the greater glory of the subsequent successful launches. But at the time, it was quite traumatic.
I’m just old enough to remember the series, as I mentioned in my June post. So I don’t remember any controversy around the airing of this particular episode. If anyone does and can shed some light on it, I would appreciate it.

. . . I decidedly *do* remember this, but it is a blast to see the pix again! From Phil Plait:
You just knew The Big Picture would take on the premier space event of the 20th century now, didn’t you?
Whoa. Head on over there for high-res spacey goodness! Many of those images made me a little choked up, in fact. Sigh.
I couldn’t agree more.
Further recollections on the 20th.

Man, this stuff never gets old:
I am happy that I lived at the right time to see this whole technology develop. Amazing stuff.
