I am returned to Techtalk Radio, discuss the end of the Space Shuttle program

English: Computer simulation of the heating of...
After weeks of missed connections and conflicts, I'm finally back to dragging down the quality of TechTalk Radio. This week, I throw out a quick missive on smartwatches, some trivia on the last cargo item the Space Shuttle placed into orbit, and lay down a challenge about the secret history of Steve Ballmer.

More importantly, Mike and Dave go deep on Google Maps tech with Daniel Seiberg. You can fast-forward past my drivel to the good stuff, no worries.

Listen to the TechTalk podcast here.

I love manned spaceflight and I'm glad the space shuttle is dead

English: The April 12 launch at Pad 39A of STS...
The space shuttle is the last vestige of NASA's poltical theater era, when big, showy, hideously inefficient and unsupportable technical projects were its bread and butter. It's Nixon-era tech -- literally -- strung along for all the same government inertia keep-the-contractors-happy idiocy that's bankrupting our national treasury.

Consider, the shuttle is a reusable spacecraft that isn't actually reusable, given that the SRBs and main fuel tank are either lost or nearly 100% refitted after every launch. It's a construction platform for a spacestation that only needs a construction platform to assemble because it was badly designed by a lets-get-everyone-involved international consortium. The shuttle can retrieve cargo from orbit -- a task that no one wants or needs. And it can ferry crew and cargo to orbit simultaneously, which is actually a terrible idea as it's cheaper -- and far safer -- to send crew and cargo up separately on smaller, task-specific craft. The Progress cargo ships and modern Soyuz capsules are examples of this principle.

Like most government projects, the shuttle looks good on camera and makes for great press, but is actually a terribly impractical and inefficient solution to a complicated set of problems.

And don't get me started on how bad the ISS is at every task it's been assigned.

Human spaceflight is 50 years old. We're past the "do it just to prove we can" stage. It's time to be grownups. It's time to build space technology that solves real problems in practical ways, rather than in ways that make contractors and photographers happy. We can achieve low earth orbit really easily and keep humans in that environment for months or years. We get it. We're good at it. Time to move on.

Now, if you want LEO cheaply, that's not what the government is good at. That's the job of the private sector. Government paves the way. The market makes it profitable. It's time for profitable LEO and human orbital habitation. NASA's job is to pave the way for the next level of hard stuff, and the next level is REALLY HARD.

Where is my advanced asteroid detection and deflection system? That's a serious problem that NASA should be solving and isn't.

Where is my proof-of-concept Helium-3 extractor for the moon, which would give us a legitimate reason for going there?

Where is my methane-oxygen autofactory for Mars, which is required before we even think about sending humans in that direction?

Where is my Lagrange-point automated telescope, which would make the Hubble look like a kid's toy magnifying glass and would actually require us to deal with serious, complex at-a-distance systems maintenance -- the kind of thing space colonies will represent?

Where is my FRAKKING SPACE ELEVATOR, which would actually be a serious surface-to-orbit gamechanger?

NASA has better things to do than keeping 30-year-old tech around for nostalgic PR purposes. I, for one, am glad to see them putting away childish things and -- hopefully -- getting down to serious business.

What was the original name of the Space Shuttle Enterprise?

Space Shuttle EnterpriseImage via WikipediaA mere 34 years ago this week -- Sept. 17, 1976 -- the Space Shuttle Enterprise was revealed to the public with a  Star Trek-themed press event. Gene Roddenberry and much of the original Star Trek series' principal cast were present, which was appropriate since it was a mass write-in campaign by Star Trek fans that prodded NASA into naming the original shuttle orbiter after the famous fictional starship.

The space shuttle designated OV-101 was originally intended to bear a different name than Enterprise, one which has some intriguing parallels to Star Trek canon.

Truly Trivial: Who does NASA's space sickness scale openly make fun of?

Astronauts acclimating themselves to space ada...Image via Wikipedia
Cosmonaut Gherman Titov owns a lot of records in the spaceflight history books: Youngest human to ever enter space (he was 25 during his Vostok 2 mission), first person to orbit the earth more than once (he did 17 orbits), and first person to vomit in outer space.

Most historians don't bring up that last bit, but it may be Titov's most important historical contribution. Titov's zero-g upchuck was the first documented case of space adaptation syndrome, known colloquially as space sickness. NASA records show that roughly 60 percent of all astronauts suffer from space sickness on their first flight. Symptoms include dizziness, disorientation, and the aforementioned vomiting, which can collectively render a space traveler useless or, worse, a danger to his vessel and his crewmates.

NASA actually has an informal scale for measuring the severity of any specific case of space sickness, one which is named in "honor" of a particularly ignominious victim of space adaptation syndrome. And no, it's not Gherman Titov.

Nerd Word of the Week: Spam in a can

Gemini 7 as seen by Gemini 6Image via Wikipedia
Spam in a can (adj.) - Space program slang term for a passive occupant in a spacecraft, specifically a space capsule. The phrase is generally attributed to Chuck Yeagar, if only because he's shown describing the Mercury astronauts as "spam in a can" in the movie The Right Stuff, though there is ample evidence that multiple astronauts and NASA officials used the term liberally during the 1960s Space Race. The early Mercury astronauts, all trained military pilots, are known to have resisted being mere "spam in a can" with no active control of their vessels, thus forcing a level of human direction into early space vehicles.

Spam in a can is now typically used as a snarky criticism of the current level of manned spaceflight technology, as humans are still travelling as meat packed into primitive metal containers and shipped long distances. This falls under the sensawunda criticism of NASA -- particularly the space shuttle successor Project Constellation, which is described as "Apollo on steroids" -- in that we are still not creating or using the sci-fi-inspired tech that books and movies has promised us for decades. Warren Ellis and Colleen Doran rather deftly pointed out the spam-in-a-can disappointment factor with NASA in the graphic novel Orbiter, wherein an alien intelligence redesigns our "primitive" space shuttle into a true interplanetary exploration vehicle.

I bring it up because: Laika passed away 52 years ago on Tuesday. For those that don't know the name, Laika was the first living creature that humans sent into space. She was a Soviet space dog launched aboard Sputnik 2 on Nov. 3, 1957. She died from overheating a few hours after launch, thus making Laika the first spaceflight casualty. Her likeness is preserved in a statue at the cosmonaut training facility in Star City, Russia, as her nation's first space traveler. Telemetry from her mission proved that living beings could survive launch g-forces and weightlessness, thus proving that spam in a can was a viable manned spaceflight model.

I also mention the spam in a can principle as a corollary to Charles Stross's recent thought experiment blog post, How habitable is the Earth? Stross essentially argues that humans are explicitly designed for a particular fraction of Earth's environment that exists during a hyper-minute fraction of Earth's geological history, thus making human space exploration -- which removes us from this environment -- a terribly difficult and expensive undertaking. Karl Schroeder recently counter-argued (the point, not Stross) that most of these problems are surmountable if we get launch expenses down and can get the proper equipment -- all of which already exists -- into orbit cheaply. Which gets us back to the spam in a can criticism: Until the tech gets better, large-scale humans space exploration is a pipe dream.
