The Onion: “Completely Unsafe Design”

NASA scientists stress that the 6-year-old’s hand-drawn spacecraft would need a top-to-bottom redesign in order for it to be “even remotely close” to flight-ready.

MONROEVILLE, PA—Listing off a litany of structural and technological flaws, the nation’s leading aerospace engineers issued a stern warning Thursday that local 6-year-old Bradley Koenig’s design for a spaceship is entirely unsafe.

Experts from the fields of aerodynamics, jet propulsion, and control engineering unanimously confirmed that the orange-and-purple rocket ship, which Koenig drew during Mrs. Silvestri’s first-grade class, not only raises major safety concerns, but could compromise the lives of everyone on board were it to ever go to launch.

“I can’t even begin to enumerate all the safety protocols and fundamental principles of spaceflight that this particular vehicle violates,” said veteran NASA flight director Raymond Fletcher, who called the crayon-drawn spaceship the “most poorly conceived” and “shockingly hazardous” craft he had ever encountered. “The asymmetrical oval shape of the craft alone would likely cause it to break apart upon reentry into Earth’s atmosphere. That’s assuming the long row of randomly spaced circular windows are properly coated with a heat-resistant material to ensure they don’t disintegrate before reaching space in the first place.”

“Bradley’s mockup ignores even the most basic laws of thermodynamics,” Fletcher continued. “This ship is essentially just a death trap.”

Fletcher, who estimated that the spacecraft would cost in excess of $230 billion given the wide array of elaborate instruments affixed to the exterior, said that the vehicle’s protruding robot arm, which he noted with alarm was more than twice the length of the ship, certainly would not be deployed during takeoff and would not be holding a large sword, as depicted.

Engineers also said that the ship’s apparent lack of oxygen generators, high-temperature insulation tiles, vertical stabilizers, doors of any kind, and an air pressurization system would significantly endanger the lives of the two smiling stick-figure crew members—distinctly labeled with blue arrows and large capital lettering as Koenig and his best friend, Joshua.

“Bradley’s mockup ignores even the most basic laws of thermodynamics. This ship is essentially just a death trap.”

“First of all, the astronauts are not secured by any seat belts or straps—there aren’t even seats to begin with—meaning that they would be thrown about the cabin immediately upon liftoff,” said former space shuttle Endeavour commander Christopher Ferguson, who noted that, even if the seemingly rudimentary boosters could generate enough thrust to reach orbit, there appeared to be no coolant system to prevent the intense 5,000-degree temperatures of fuel burns from vaporizing the entire craft. “In addition, the large glass dome surrounding the cockpit would shatter almost instantly from the intense atmospheric pressure of reaching escape velocity. They won’t be playing on a basketball hoop on the flight deck when that happens, I assure you of that. They would be propelled out of the module and suffocate within seconds.”

“I would not even consider piloting such a craft without extensive safety modifications,” Ferguson added.

Ferguson also said that the two variously sized wings mounted to either side of the spacecraft would compromise its flight trajectory, sending it careening dramatically off course during launch. He further explained that the cockpit’s steering wheel would be virtually useless in such a situation.

“We must have run at least 200 3D computer simulations, and there is simply no scenario in which the periscope doesn’t at some point break off and rip an enormous hole in the command module,” said Paulo Lozano, director of the Massachusetts Institute of Technology’s Space Propulsion Lab. “And unless Bradley has discovered a new form of liquid propellant I’m unaware of, it’s fairly obvious that with so many flames shooting from the engine, the fuel supply would be depleted within a matter of hours, leaving the craft immobilized and left to float off forever in the void of space.”

“And, needless to say, navigating any manned ship so close to a giant speeding asteroid is also unbelievably dangerous,” Lozano added.

Despite the clear and irrefutable problems in Koenig’s design, experts did admit that the ship’s giant laser cannon for shooting space monsters was the most awesome thing they had ever seen.

Astronomy Picture of the Day: “Two Worlds, One Sun”

How different does sunset appear from Mars than from Earth? For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here side-by-side. A quick inspection will reveal that the Sun appears slightly smaller from Mars than from Earth. This makes sense since Mars is 50% further from the Sun than Earth. More striking, perhaps, is that the Martian sunset is noticeably bluer near the Sun than the typically orange colors near the setting Sun from Earth. The reason for the blue hues from Mars is not fully understood, but thought to be related to forward scattering properties of Martian dust. The terrestrial sunset was taken in 2012 March from Marseille, France, while the Martian sunset was captured last month by NASA’s robotic Curiosity rover from Gale crater on Mars.

Why Reusable Rockets Make Asteroid Retrieval Worthwhile

Ice extracted from asteroids or lunar craters will not be competitive with fuel launched from Earth on reusable rockets costing fifty thousand dollars. This should concern us.

15 tons of high quality fuels trucked from sophisticated refineries in Houston then launched for $250,000 on Falcon 9s in Brownsvile will always outcompete expensive fuels cracked from water-ice extracted out of lunar craters using as of yet non-existent multi-billion dollar technologies. In fact, the ability to launch tons of fuels from Earth to LEO on reusable rockets may delay the development of in-space resource utilization for decades.

When Musk achieves reusable rockets, development of all near Earth resources may be delayed from any cislunar source – even unfortunately asteroids with their superior concentrations of ore and favorable zero g environment. This ironically however provides a reason for taxpayer support of asteroid retrieval: private/public research partnerships teleoperating on an asteroid in Earth orbit owned by all U.S. citizens (NASA) could jump-start technologies humanity will need to develop asteroids. Humanity needs access to asteroids long-term. Asteroids – not the moon – will fuel a billion-fold increase in our industrial base. Despite a huge disparity in initial cost-competition with launches from Earth, government subsidized R&D on asteroids placed in an elliptical orbit around Earth could advance for-profit Free World leadership of in-space resource utilization by decades.

Transcript:

The human need to explore is deep within all of us. Our ancestors crossed mountain ranges, sailed archipelagos, and sought out the unexpected – while always looking to the stars. We are curious. And now, we’re at a place where we can pioneer new horizons. Because Earth – this blue planet, in all its beauty – is just our starting point. Now is the time to open the promise of space to all. And lay the way for generations to come. When our descendants look to the stars – perhaps from a rocky moon or colonies floating in open space – they’ll remember this time, when they’ll reflect on where it started, they’ll remember this place. And when they honor those first explorers who said, “Let’s go.” They’ll remember these bold steps. We are [“of” or “a”?] blue origin. And this, is where it begins.

(Jeff has a perfect deep voice for this but intonation needs to vary. After the first sentence it is not passionate enough, and comes across as unexcited, sleepy. These words are also too plain (for example “let’s go” delivered with a period rather than exclamation)…compare Jobs reading “The Crazy Ones” with a far less perfect voice in pitch but genuine heartfelt emphasis and modulation: https://www.youtube.com/watch?v=eAVW-jLRLE8 Anyhow, congratulations!)
