It looks like Amazon may be taking a step into the big world of (more) monopolistic practices. Here
is a story (with multiple updates and comments) about their efforts to consolidate production of print-on-demand (POD) titles
within their own company. Any publisher that doesn't comply with the 'request' has their titles removed from standard Amazon
ordering (such as the 'buy now' button and eligibility for free shipping).
Space: What Now? has been effected. I'll be monitoring the situation over the coming days, slowly decreasing my reliance
on Amazon. I've really liked them in the past, but this seems to cross a line somewhere.

While I was awaiting my active duty orders for the Air Force, I worked as a civil servant at the Air Force Astronautics Laboratory,
taking up a corner of Edwards Air Force Base
. It was a cool experience for a fresh out of college, newly-minted second lieutenant. Where else can you see space shuttle
on your way to work, followed by 747 piggyback
(be sure to check out the instructions on the orbiter mount
) flights. I also got one of my best pictures ever during that year (shown on the right, archive version here
). It shows Endeavour
leaving the Palmdale facility where it was built. The most exciting event, however, was the
of a test Titan IVb solid rocket motor. I can't find a picture of it on the web with a quick search, though I took a roll
of film and ordered hundreds of picture reprints for people in the office. Oh yeah, I guess there were some cool aircraft
to, like the B-2, YF-22 and YF-23
Anyway, I got a bit nostalgic last night, looked for some history on the old lab, and found it

Another Creepy Robot
7:42 pm est
I found this
amazing to watch. The concept is a 250 pound vehcile that can carry 350 pounds of equipment and follow an infantry group
around varying terrain. To watch this four-legged 'thing' maneuver up snow-covered slopes, slip on the ice and recover, and
remain standing after someone kicks it brings home once again how amazing robotics are getting. Of course, if you add a person
, you get something much more maneuverable.

While I make no claims to great fame, I've enjoyed my time so far writing books and articles for the space community. A buddy
of mine, John Overstrom, is big into electronic tinkering. We used to work together and I'd bore him with my latest articles.
Well, he's started to document his own activities, and his first article will be the cover feature in this month's Servo
Magazine! Congrats, John!
Oh, and this post is even somewhat space related, since his article details his GPS
-guided kiddie car.

"Hot" on the heals of the recent Titan news
comes the story that Enceladus
is spewing complex organic molecules
(like formaldehyde, propane, stuff much heavier than the expected methane) from a warmer-than-expected
subsurface ocean. This holds great promise for the potential for life
According to the Wikipedia article
, there are several more close encounters with Enceladus scheduled, so the fun is just beginning. What an amazing place our
solar system is turning out to be!

Orbit@home Online for Alpha/Beta Testing
5:56 pm est
, I commented on Orbit@home
, an effort to do tedious NEO impact predictions using the BOINC
distributed computing platform. According to their website, you can sign up now, but they're working through initial bugs.
I've signed up, but haven't received a work unit yet.
I'm going to suggest that, as an extension, they look for low delta-v mission opportunities as well. Something tells me that,
once this takes off, they'll be amazed at the computing power they've tapped into.

Where no LEGOTMhas gone Before
7:21 am est
To me, the LEGOTMDigital Designer
software has revolutionized the conceptual modeling of new spacecraft. My latest creation is pictured on the right, (archive
) and shows a manned spacecraft approaching the asteroid 1998 KY26
. The light image shows more detail of the craft, while the dark image is more like what the scene would actually look like.
A CEV is attached at the top, which is connected to an expanded living area and a boost stage. I'm working with a friend
to determine when some of the best windows open for exploring local asteroids, and what kind of delta-vs are necessary for
For the record, 1998 KY26 is spinning so fast (1 rev every 10 minutes or so), it's unlikely that anyone could do serious research
or research extraction on its surface as things stand. That said, it is a carbonaceous chondrite
, meaning it is made up partially of water. That would make it a useful target, though I think its rotation rate needs to
be altered first. Another possibility might be placing a big net around it.

Yahoo movies has a list
of the most historically inaccurate movies of all time. I agree with nine of them, but when they listed 2001: A Space Odyssey
, I had to call foul. Saying that William Wallace wore kilts 300 years before they came into vogue is one thing, but not
predicting correctly more thirty years in the future is a whole different story!
All These Worlds are Yours...
6:00 am est
The list of fascinations about fascinating moons continues to grow. It turns out that Titan has an underground liquid ocean
. The press release goes as far as saying that the ocean is made up of water and amonia, but there's no mention of the technical
measurement that led to that conclusion. I will stick with 'liquid' (accepting that it may be water and amonia) until further
study comes through. In my discussions with people of different viewpoints, they've (rightly, in my opinion) pointed out
to me that we tend to get too specific too quickly on new discoveries.
The discovery was made because surface features on Titan have shifted by up to 30 kilometers over time since Cassini
started taking radar measurements. Therefore, the surface of the moon is not attached to its core.
For those who didn't recognize the title of this post, it's in honor of the recently-passed Arthur C. Clarke, from his book
2010: Odyssey 2
, and even the movie
included this part of the quote, though the quote's end was altered.

Think you own a Meteorite?
8:45 pm est
I have a couple rocks sitting around the house that looked weird when I picked them up. I always thought they were meteorites,
but never knew who to ask. Thanks to the miracle of the web, there are a few tests
you can run at home to find out if you own a piece of primordial solar system junk. The tests boil down to:
- is the
rock magnetic? (most meteorites are)
- Does it leave a mark when rubbed on rough ceramic? (most meteorites don't)
it have small flecks of material within it? (most meteorites do)
- Is it heavy for its size? (nearly all meteorites are)
your rock passes these tests, the linked web page gives you information to contact them for further consultation. In my case,
the rock I tested appeared slightly magnetic, parts didn't leave a mark on rough ceramic, I dulled a file trying to look for
flecks internally, but its density
(measured as 2.08 g/cc) didn't fall into any of the meteorite categories. It still looks cool on my shelf. I may try a
grinder on it next time I head to my mom's.
Quite a Question
4:16 am est
I'm not sure what all this
is about, but the topic of discussion catches the eye:
Are there any qualified individuals who would be willing
to travel to the Moon or Mars in an “austere” craft and face dangers comparable to those faced by the Apollo 11 crew, by Charles
Lindbergh, and by Edmund Hillary and Tenzing Norgay on Mount Everest?
It sort of reminds me of Shackleton's call
Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful.
Honor and recognition in event of success.
Reading on, it's posed as more of a thought experiment, but thought
experiments lead to some pretty cool things!

Silence all Satellite Communications for a Moment...

The first person to popularly suggest them has died
Sir Arthur C. Clarke, the creative force behind some of the best science ficiton of the 20th century, has gone the way of
the star child and left his Earthly body behind. His wrote some of the first scifi I read, and he remained my favorite writer.
I just wish that he could have lived long enough to see Maelstrom II

A Little History I've (Virtually) Touched
7:49 pm est
's an article on Vanguard 1
, America's second successful satellite. It's still in orbit, circling as it has for now 50 years. The article discusses
some possibilities for recovering the spacecraft, as well as what we could learn from it and some ways that a mission to recover
the craft could be paid for.
What's my part of the story? When I was overseas at Pirinclik
Air Station, Turkey, it was my job to track space debris and some active satellites for the Air Force. We'd receive requests
from Cheyenne Mountain to update orbits for specific satellites, and one time a task came to track Vanguard 1. It wasn't
any different than tracking our other objects, except that I grinned.

The meteorite that fell in Peru
last year has some researchers confounded

Update: More theories are discussed here
A Debatin' we will go...
5:32 am est
It's unlikely that I'll ever mention political favorites on this site, just because I think it clouds any other issues. I
do understand the role politics plays in space, as much as I hope that role will decrease in the future.
In the 'generic politics' category, the (likely) upcoming Science Debate 2008
seems to be catching on. Alan Boyle
has some background on how the debate became relevant, and more (though not very) likely. It has the potential to be the
first time that the three candidates all appear on the same stage. If other scenarios had panned out, it would have been
more likely to be held after each party's candidate was established.

News release from NASA:
HUBBLE DETECTS ORGANIC MOLECULE ON AN EXTRASOLAR PLANET
WASHINGTON - NASA will hold a media teleconference at 2 p.m. EDT on Wednesday, March 19, to report on the first-ever detection
of the organic molecule methane in the atmosphere of a planet orbiting a distant star.
Though the planet is too hot to support life as we know it, the finding demonstrates the ability to detect organic molecules
spectroscopically around Earth-like planets in habitable zones around stars.
Even though this planet isn't a
likely place for life, proving that we can find methane (a good indicator of life potential, under proper circumstances) bodes
well for the search.

help find some NEOs I'm sure. Of course, the big 'scope
for that will come on line in 2010

I just recently learned that the European ATV
was designed to be human-rated (in whatever passes for that nowadays...I probably need to have a standard disclaimer to link
to for an explanation on this, but Rand Simberg
says most of what I'd say) for eventual addition of a crewed capsule. The fact is mentioned here

over at Transterrestrial Musings about what looks like the new approach for an Ares-based moon launch: launch the crew first,

Related to this post
, I spoke with a friend who's knowledgable in such things last night. He says our understanding of Earth's masscons (mass
concentrations, basically the things that make our Earth a non-sphere) is incomplete enough to account for the flyby anomaly.
This would explain why the effect is inconsistent, because it would rely literally on exactly where each probe flew over the
Earth. For example, in one flyby a craft may be closest to Earth over North America while in another the craft might be closest
to Earth over Africa. Different masscons would accelerate the spacecraft differently, though only slightly.

Delayed Mars Science Lander?
I'm seeing more noise in the press about a potential delay in the Mars Science Lander program. No idea whether it's because
the chance of delay is actually increasing, or there's a feeding friendzy over one morsel about a potential slip.

If cost is the issue, a delay of two years will only increase the problem.

Just saw an old article
about the new Pixar film Wall-e
. In the review, they say that the movie shows humans 700 years from now, living in space and essentially morphed into giant
couch potatoes. The article claims that Pixar is trying to "focus group" the movie to see if people respond to the idea that
we will look like that if we don't spend more time on the treadmill (I'm kidding...going outside would obviously be better).
My thought is that even if were weren't couch potatoes before going into space, we would become that way if we lived in zero-g
for a long period of time, especially if we bred in space. On Earth, we can avoid the couch potato syndrome by exercising.
In space, you can avoid it by generating artificial gravity

is more discussion on the Pioneer Anomaly
as well as the Flyby Anomaly
. It looks like additional information was gathered, in that the MESSENGER
flyby was almost exactly symmetrical around Earth's equator, and no anomaly in its velocity was found.
Side note: if you check the MESSENGER page today, you'll see that we're 1111 days to orbit insertion. A meaningless number,
I know, but it looks cool nonetheless.
