And then there’s yours truly, who will be delivering a paper and presentation on External Tank-derived heavy-lift launch vehicles.

Low on Fuel

Space.com has an article on the planned resumption of Pu238 production for power purposes (note the date on the article). It also links to a similar article on the subject from this time last year.

I find it surprising, to put it mildly, that we are relying on Russia to provide us with nuclear material for use in our spacecraft. In 5-7 years, however, we will apparently have a new production facility on-line (if DoE gets its wishes), which will enable us to produce enough fuel for upcoming nuclear-powered probes (possibly including Prometheus, but I don’t know if anyone yet knows what sort of fuel it will require).

Thinking the Unthinkable

While catching up with The Astrobot Diaries just now, it occurred to me to wonder: what happens if something goes wrong en-route?

Biff is now two weeks out, on his way, and it’s quite likely that he’ll be fine until Spirit closes on Mars and has to make its final insertion maneuvers. What happens then? What happens if Spirit goes the way of Mars Observer, blowing itself up at the last moment as it prepares to fire its engines? Or what if something else goes wrong (something as unlikely and farfetched as, ohh, a unit conversion error or suchlike), and Spirit burns up in the atmosphere or craters into the surface?

What happens to poor, dumb Biff? Hasn’t anyone thought through the consequences?

Well, I think we all know what would happen to Biff. The real question here is how does the Astrobot Diaries handle this little problem — especially given the audience at which the site is targeted? Do they paint their website black, offer up mournful tributes to Biff the Fallen Hero, and deny to the end of time that the scurrilous rumors about a final, panicked email from Biff consisting entirely of the exclamation “AAAAARRRRRRGGHHHHH!” are in any way based in fact?

And what of Sandy Moondust, the pioneering female astrobot, still awaiting her launch from KSC? Biff is already on his way, but she still has ahead of her perhaps the most dangerous part of her mission. What happens if the Delta rocket blows up on launch? Will there be teams of frogmen dredging the seabottom, searching for her sad, melted remains? Will the world be horrified and saddened by Pulitzer-winning photographs of her shattered, empty space helmet lying forlorn atop a tangled mass of seaweed on Cocoa Beach?

Will we all be asking ourselves, in the days and weeks afterwards, if something more couldn’t have been done to save her?

And even if both Biff and Sandy survive to successfully carry out their missions on the Martian surface…what then? Clearly there is no way to bring them home, and that is the saddest part of all: Biff and Sandy, our noble astrobot heroes are headed out on a one-way trip — a suicide mission.

To make matters worse, those bloodless bastards at Astrobot Corps must already know it. And yet they apparently haven’t bothered to tell the crew. If it were you strapped to a mini-DVD on one of the MERs, doomed to a lonely death, abandoned on an inhospitable planet far from the familiar comfort of your friends, your production lot, and the injection molding factory of your birth, wouldn’t you want to know your life was in danger? Who knows but that Biff and/or Sandy, if given enough time, might just come up with some way out of the jam they are (apparently unwittingly) getting into? Maybe there’s nothing they can do to save themselves, but shouldn’t they at least be told, so that they might prepare for the inevitable, make their peace, and face the end with calm dignity?

What we are witnessing here is a tragedy unfolding before our eyes. And it’s only going to get worse from here, as Biff and Sandy steadily approach their very public appointments with the Reaper (or the Ghoul, whichever one gets them first).

Some will ask why the astrobots can’t rescue themselves by making a daring traverse to the safety of one of the Viking landers, whose RTG power units should have enough heat left in them to keep Biff and Sandy above their glass transition temperatures until the Astrobot Corps can mount a retrieval mission to bring them home safely. Well, unfortunately, the Viking landers are located in Chryse and Utopia, well out of the travel range of the MERs, which will be landing in Gusev and Meridiani — it’s physically impossible for the rovers to travel to those safe havens. Others may ask why they can’t be saved by the upcoming Mars Sample Return Mission: just launch it a bit early, meet up with the astrobots, scoop them up into the return vehicle, and bring them back to Earth. Unfortunately, it doesn’t work that way — for one thing, NASA can’t prepare a sample return mission that quickly, but more importantly, a rendezvous and rescue like this has never been attempted or even practiced, so it is likely that not only would the astrobots and their rovers be lost, but the sample return vehicle sent to rescue them as well.

The Planetary Society Launches Global “Mars Day Celebration”

On August 27, the planet Mars will be closer to Earth than it has been in more than 50,000 years. The planetary event will enable the public, space enthusiasts and astronomers to view greater detail on a planet that is increasingly seen as humankind’s next giant leap.

Bright red-orange in the evening sky, Mars will be in perihelic opposition this summer, meaning the celestial body is at a point in its orbit when it is both closest to the Sun and to the Earth.

To celebrate this once-in-a-lifetime event, The Planetary Society will mark this occasion with special events around the world, including an 83rd birthday party for a man whose name is now synonymous with the Red Planet – Ray Bradbury, author of the famous The Martian Chronicles.

More Ice on Mars

NASA’s Odyssey Orbiter Watches A Frosty Mars

The news about water on Mars just gets better all the time:

The study also found once the dry ice disappears, the remaining surface near the pole is composed almost entirely of water ice.

Off the Deep End

Today I received the latest Spacefaring Web (3.12: “Closing the Final Frontier”) from John Carter Mcknight.

Sorry, no link…because, of course, his website is still a useless mess.

It’s mish-mash of paranoid handwringing:

Now, in an age of bioterrorism (a term unrecognized by my Word 2000 spellchecker, amusingly enough), preventive war, recession, and that sense of dis-equilibrium that precedes collapse, those days of the cyberspace frontier do seem like a lost golden age.

…dire and overwrought warnings of impending enslavement:

What was once the American military-industrial complex has become the infrastructure of global empire. Within a lifetime, it could spread through the Solar System, and any future space colony could look an awful lot like occupied Iraq: the steady flow of resources to the shareholders back home ensured by the legions, with neither the employees nor the wogs having the freedom to criticize management.

…anti-military and anti-corporate cliches:

But these companies have an established way of doing business, one built upon unaccountable power. In Iraq, the symbiotic relationship between army and contractor yields a logic of repression: threats to the nominally-civilian contractors, or the economic assets they control, lead to repression of civil rights by the military occupation, which exacerbates resistance, and on. Given that guard duties are performed by contractors, with a different set of rules of engagement than the publicly-answerable Army, even civilian inquiry into management practices may be met with threats of deadly force.

…handwringing over the dreaded Military Industrial Complex™:

There will be space hotels, and orbital O’Neill colonies, and science towns on Mars. But they won’t be built by the plucky entrepreneurs with tables at space-advocacy conferences. They’ll be built by companies like Kellogg Brown & Root (KBR), Bechtel and Booz Allen Hamilton. Companies that are effectively wholly-owned subsidiaries of the US Department of Defense – or vice versa.

…and generally continues his recent downward trend.

I used to really enjoy reading his essays. Unfortunately, they’ve steadily turned to crap…from interesting perspectives on different avenues to and social and political aspects of space settlement, to venom, histrionics, and paranoia. It’s disappointing.
