SPACEX BOSS SAYS - MARS HERE WE COME! MEANTIME, HERE’S A FREE MODEL MARS ROCKET


SMN report:
SpaceX CEO Elon Musk confirmed the planet Mars as his long-term goal during a speech on 29 September at the US National Press Club. Already known for its Falcon rockets and Dragon space capsule, SpaceX is to make them reusable. The Falcon 9 will incorporate a descent module at the base, so that it can make a vertical soft landing, while the Dragon (above) will use its emergency-escape rockets as brakes on the journey back from space.

Cracking the engineering problem
Musk said: “It's a very tough engineering problem, and I wasn't sure it could be solved." However, he went on: "In the last twelve months or so I've come to the conclusion that it could be solved, and I think SpaceX is going to try to do it. The idea looks promising, added Musk: “We have a design that on paper, doing the calculations, doing the simulations, it does work."


Let's hope crosswinds won't affect Falcon 9's landings too much!

Economic issue
Good for you Elon, but why bother? It’s a question of economics: “The Falcon-9 costs $54m, but fuel and oxygen and so forth is only about $200,000. So obviously if we can reuse the rocket, say 1000 times, then that would make the capital cost of the rocket launch only about $50,000." 

Road to the Red Planet
In fact, it’s the same set of sums the airlines use when working out how to fund a hugely expensive jetliner - what price your next vacation if the jet was thrown away after every flight? And of course, if SpaceX lowers the cost of spaceflight, then it could mean the road to the planets - and Mars in particular - is open.

The legacy of Wernher von Braun
It's about time someone took a long-term view of spaceflight - we certainly cannot leave it to the politicians and their vote-hungry, budget-cutting, short-termism. The long view is not new however - the architect of the Apollo moonflight program, Wernher von Braun, came up with feasible Moon and Mars rockets way back in the early 1950s. 


Free paper spaceplane
It’s one of these designs - a huge winged cargo ship for Earth orbit operations - that’s the subject of the free downloadable paper model. And a similar ship, with bigger wings and cylindrical fuselage, was envisaged as being able to glide through the thin Martian air, to make a horizontal landing on the rust-red sands. We reckon that this paper rocket could be made up in either form with not too many mods. The paper rocket is designed for an A4 printer, and at that size the ship is to a nominal 1:100 scale, but as ever with these paper products, the scale can be varied by changing the output percentage on your printer, though you'll need an A3 printer if you're thinking of a 1:72 scale model.

Popular magazine
Von Braun’s Mars Expedition concept was published in the pages of Colliers, a popular news magazine of the time, and even today looks a carefully conceived and futuristic plan. The inflatable living sphere looks a great idea, if somewhat top-heavy!


Snowcat-style rover featured a shirtsleeve-comfort living sphere.

Enjoy making the model - it ought to make an interesting change from plastic.

A more than decent cgi animation of the SpaceX system in action (it’s a slooow loader, but worth it - and do crank your bass up for the music track) is here.


SMN’s own David Jefferis has written the Exploring Planet Mars book (above and below) which is available on Amazon here. Watch out for the amazing ebook version, due next year.

DRAGON SPACECRAFT RETURNS FROM ORBIT! X-37B LANDS ON RUNWAY!






SMN report
News that the US company SpaceX successfully test-flew its Dragon space capsule today makes SMN really proud - for this company is in the vanguard of the privatization of space. Along with the likes of Sir Richard Branson’s Virgin Galactic program, it looks as if there might be a future for rocketry in the post-Space Shuttle era after all.

Spacecraft models from Dragon
And talking of Dragons, the Chinese model company of the same name is busy releasing a miniature ‘Space Collection’, to 1:72 and 1:400 scale, plus 1:6 scale astronaut figures. The spacecraft are all ready-built, mixing diecast metal with injection-plastic parts, and while some are familiar subjects - Apollo and Shuttle feature strongly - there is at least one really interesting of-the-moment release, and that’s the 1:72 scale X-37B OTV (Orbital Test Vehicle).

X-37B in space
Looking much like a mini-Shuttle (and originally designed to fit inside a Space Shuttle cargo bay) NASA’s X-37B program was taken over by the US Department of Defense in 2004. The craft saw its first orbital flight on April 22 this year, and stayed aloft on a secret mission until returning just last week, on December 3. The X-37B is a completely automated winged vehicle that lands on a runway like the Space Shutttle.

Comparing model with reality
The Dragon X-37B is a neat piece of model engineering that sits on a stylish stand. However, it’s interesting to compare the smooth and sleek lines of the 1:72 scale model with the lumps, bumps, and varying textures of the real thing, as seen in the official pictures above. And look at those white protective suits - the engineer-techs look for all the world like extras from a Hollywood sci-fi blockbuster - Close Encounters anyone?!

Well done Dragon for this X-37B - it’s an unusual subject that’s been well captured. Let’s hope the company will provide a 1:72 scale Dragon capsule soon, preferably with a seven-astronaut crew inside!

We’ll be showing a neat diagram of the Dragon capsule and other spacecraft in the next day or two - keep your eyes peeled for that.
