Twenty-Eight Years

My post from three years ago says pretty much everything I have to say.

However, I was struck by the video that's recently surfaced.

Never forget the courage, the sacrifice, and that the crew of STS-51-L, Commander Francis R. Scobee, Pilot Michael J. Smith, Mission Specialists Ronald McNair, Ellison Onizuka, Judith Resnik, and Payload Specialists Greg Jarvis and Christa McAuliffe, believed in man's place in space.

Fourty-Seven Years Ago Today.

The Apollo 1 fire.

Lost were Virgil I. (Gus) Grissom (one of the original 7 Mercury Astronauts), Edward H. White II (the first American to perform a space walk), and Roger B. Chaffee (on his first NASA mission) were lost when a first broke out in the pure oxygen atmosphere of the command module during a "plugs-out" test of the craft on the launch pad.

All three men were dead within 30 seconds of asphyxiation and severe burns.

Grissom, White and Chaffee
 The heat and pressure were so great that the command module's hull ruptured within 15 seconds.


The accident led to many changes in the construction and design of the Apollo Command Module, and the sacrifice, however undeniably tragic, helped in making future Apollo missions safer.

Whatever your belief, God bless the first men who gave their lives for what I consider mankind's greatest achievement. Who willingly risked all so that man might leave Earth, and stand upon the moon.

An Era Slowy Winds Down

You probably don't know this, but Space Shuttle Discovery is scheduled to liftoff for the final time. This will be her 39th mission for NASA.

Endeavor and Atlantis have scheduled missions for later this year, and that will be the end of America's Shuttle program. I have to admit, I'm a bit melancholy over the whole thing. I always intended to go to Florida to see the shuttle launch once. One of those things you figure you'll always have time to do "someday."



Countdown
Lyrics by Neil Peart

Lit up with anticipation
We arrive at the launching site
The sky is still dark, nearing dawn
On the Florida coastline

Circling choppers slash the night
With roving searchlight beams
This magic day when super-science
Mingles with the bright stuff of dreams

Floodlit in the hazy distance
The star of this unearthly show
Venting vapors, like the breath
Of a sleeping white dragon

Crackling speakers, voices tense
Resume the final count
All systems check, t minus nine
As the sun and the drama start to mount

The air is charged --- a humid, motionless mass
The crowds and the cameras,
The cars full of spectators pass
Excitement so thick --- you could cut it with a knife
Technology --- high, on the leading edge of life

The earth beneath us starts to tremble
With the spreading of a low black cloud
A thunderous roar shakes the air
Like the whole world exploding

Scorching blast of golden fire
As it slowly leaves the ground
Tears away with a mighty force
The air is shattered by the awesome sound

Like a pillar of cloud, the smoke lingers
High in the air
In fascination --- with the eyes of the world
We stare...

A Quarter of a Century

There's a couple of events I remember clearly in my life. 9/11, of course, the afternoon Reagan got shot...

But the Space Shuttle Challenger disaster is right up there. I can recall being in class, High School, and everything stopping. Televisions wheeled into rooms, and watching what was going on. I gotta tell ya, it really is stunning to be that it happened a quarter of a century ago. I know people who weren't alive when the Challenger fell to Earth.

I was fourteen, by my calculations, when it happened. I was a hard-core nerd/sci-fi junkie, so the space program meant, and still does mean, a hell of a lot to me. I confess, I wasn't watching the launch that day (I was in school), and, yes, the idea of shuttle missions had become routine and...well, kinda dull.

There are many times I wish I could've been around to see the Apollo program. I can't imagine what it must've been like to watch those grainy black and white images of Neil Armstrong and Buzz Aldrin climbing out of the LEM. I have a DVD of the live video feeds from the Apollo 11 mission, from launch prep to splashdown. Three DVDs filled with this primitive footage of three brave men stepping out into the unknown.

If something had gone wrong with Apollo 11, I can't imagine anyone would've been overly shocked. It seems, from the accounts I've read, that there was a universal understanding that, while we had dedicated maximum effort and resources to this endeavor, it was a difficult and dangerous journey. Every space flight is.

I think that morning in 1986, we had long forgotten that. The public, that is. I truly believe that every one of those seven souls on Challenger knew exactly the dangers and possible consequences they were facing. I truly believe it's impossible to be at their place in the program and not be. I think that's also reflected in the fact that all of the families of these lost astronauts expressed that exact sentiment.

But us? The public? It was a tragedy we had never seen before. We had lost astronauts, Apollo 1 had burned up on the pad during a training run, killing original Mercury astronaut Virgil "Gus" Grissom, as well as the first American to ever perform a spacewalk, Ed White, and Roger Chaffee. Those three men died in a tremendously horrible and, likely, unexpected way.

But they were on the ground. Burned to death in a sealed, pure oxygen environment. Strapped into their seats and with no way to open the hatch in time. The technicians outside couldn't get to the hatch to open it, because of heat and smoke. It only took seconds, but the three men were gone.

I often think that, for the astronauts, it was probably harder to think of dying on the pad, performing some routine test, than in orbit, or halfway to the moon. The Apollo 13 mission, so well documented at this point, must've seemed so much more logical. The type of thing you suspect might happen, in general, if not in the details. You see in the actions of that crew, Jim Lovell, Jack Swigert and Fred Haise, they knew trouble might occur, and your job, as an astronaut, was to be flexible and adaptable enough to deal with anything that might happen.

Liftoff is a very dangerous part of the flight, but it's also a point where the crew is, basically, in the hands of ground control, and the craft itself. The great tragedy is, of course, that the latter simply failed. This vast, beautiful spacecraft exposed the failings of it's launch system design and construction, and took seven brave souls with it. Of course, now, looking back, we know the problem stemmed from the O-rings on the solid rocket boosters that propelled the shuttle out of the atmosphere. One of the rings ruptured, and sent a jet of super-heated rocket blast into the external fuel tank, which erupted into flame, and broke apart.

Challenger didn't explode, as most people remember it. It broke apart. It fell to Earth in pieces. This, of course, leads to all sorts of questions about how long the crew lived, and what their ultimate fate was. Did they live until the wreckage struck the water? It seems likely, but it also seems likely they were all unconscious most, if not all of the fall. It's not something to dwell over. The crew is dead, and dragging up how the last moments of their lives may or may not have played out will do no one any good, especially twenty five years later.

Yes, human error led to the disaster. Be it the design of the boosters, or the decision to launch in the midst of record cold Florida temperatures. There is plenty of fault to be found, and plenty that has been created, nurtured by the fringe of the internet. If you want details, there's a lovely, honest piece by former NASA designer James Oberg over at msnbc.com. Oberg presents many facts, and defuses some of the more ridiculous claims.

Mistakes were made, warnings unheeded, but no one is to blame for what happened. The shuttle had launched twenty four times previously with no major incident. Sure, the NASA team may have become somewhat complacent, but the shuttle was constantly being improved and upgraded, just not quickly enough. There was pressure to meet the launch window for the payload on board. All of these things, however, had been in play before, and would be after. What happened on that January morning was that all of these issues combined into a deadly result.

I know Mr. Oberg takes some task with what I am about to say, but I truly do feel this disaster, and the more recent Columbia disaster in 2003, while not inevitable, are not entirely unexpected. NASA has launched one hundred and thirteen shuttle missions to date, and these two are the only ones to experience catastrophic malfunction.

Any loss of life is unacceptable, but we are all human, mistakes will always be made, accidents will happen. We're also dealing with craft designed to be used over and over again, unlike the craft of the Mercury, Gemini, Apollo and Spacelab missions. Those rockets were used, burnt up, or floated off into deep space. They only had to work one time. The shuttle is asked to function over and over again, and as we all know form our own cars, or computers, eventually a machine is going to break down. You can check and re-check, but there's always a chance something will be missed.

Put into context, NASA's record is quite good.

Now, the shuttle program is winding down, probably rightly, being put into mothballs. We'll go back to conventional rockets again, and the vast majority of our manned excursions will be centered on the International Space Station. The shuttle was always a mistake. Sure, it was useful at times, but it was also a long, costly sidetrack from the other NASA plan presented to President Nixon (always comes back to Nixon, doesn't it?). A step-by-step plan to reach Mars sometime in the 80's.

We'll never really know if that would've worked. I tend to believe it would've, and how much further would we be now?

That aside, I take a moment to remember the Challenger, and her valiant crew.

Birthday presents...and other musings.

I'm excited by my lovely wife's gifts to me on my 38th (ugh!).

I'm re-reading my new copy of Star Trek Memories by William Shatner. Easily my favorite book about Star Trek, and the new printing is very, very snazzy. Hopefully a new edition of Star Trek Movie Memories will be forthcoming.

The whole think is, rightly, from Shatner's perspective, and he's an engaging storyteller. Though, I'm certain that "co-writer" Chris Kreski actually wrote most of the book. The stories are entertaining, and he's honest and direct about his poor relations with the rest of the cast, as well as his befuddlement at their hatered of him. A fun read.

I'm also REALLY excited about my new Bone: One Volume Edition, by Jeff Smith. The book is HUGE, well over 1000 pages, and containing the entirety of Smith's comic book/graphic novel masterpiece. Not something I'll be hauling on the train, but I'm gonna try to read a chapter or two every night before bed. I'm kind of ashamed I haven't read this before now, as it truly is a classic, and I've found myself laughing out loud on a number of occasions.

Also got a number of DVDs and Blu-Rays, especially cool is For All Mankind, Al Reinert's amazing documentry on the moon landings. I'm so excited to watch this in Hi-Def. New Torchwood and Doctor Who to watch, as well.

In other news, first night of actual rehearsals for Plans 1-8 from Outer Space last night. Of course, I hurt myself. I think I bruised a rib on my right side.

*sigh*

Just figures, right?

Short weeks always go slower, don't they? We're wrapped up for Plans 1-8 this week, but I have the "Trekkie Play" workshops on Saturday and Sunday. Lots of stuff going on, and I feel really tired. The crap with the ribs doesn't help, sucks the energy right out of me. LOL!

Need to get back to working out. Seriously, nothng like going to LA to make you feel out of shape.
