SPACE-X IS TEN YEARS OLD - AND NOW TAKING US BEYOND THE SHUTTLE ERA



SMN report from David Jefferis:
SpaceX is the sort of company that brings a smile to the face of many a space buff. Under the leadership of Elon Musk, who set the company up a decade ago in 2002, SpaceX has gone from strength to strength. Right now, SpaceX is aiming to make the first commercial flight to the International Space Station, using its Falcon 9 rocket and Dragon capsule combo. And guess what? There’s a model rocket available from SpaceX that you can build and fly.



Amazon supply details
First things first: the only supplier we know of at the moment is Amazon, and they don’t mail the SpaceX rocket  to all countries, so x-fingers you live in an approved locale. Even so, it’s an interesting item, and at about $30 USD, pretty fairly priced, too. When assembled, the kit measures 580 mm (22.8 in) high, equating to 1:88 scale. 


Building the beast
Assembly is very simple, and it’s compatible with Estes model rocketry products, which is a high recommendation, as this writer has flown many an Estes rocket off the pad, and it’s huge fun, even if you do stand to lose the occasional model. 


What a choice
I recall one successful launch, moments after which my partner of the time decided that she was about to have our baby! Suffice to say, the last I knew of that camera-equipped beauty was the sight of it drifting under its parachute, far away into the January mist, never to be seen again. I didn't have to time to fret about it though - after a speedy dash to hospital, I helped the midwife deliver a beautiful baby daughter!


Static or flight mode
Back to the SpaceX kit. You can build it static or flying - it’s your choice, and a parachute is included for flight recovery. Non-scale, but necessary for model flying are the transparent tailfins, which you can leave off if you decide on a static display model.



Summation
A great idea from a pioneering company, and good news for us that SpaceX is into the model spacecraft game. If the SpaceX Falcon-Dragon kit raises some cash to help US astronauts return to the space race, so much the better. 


Humans in space
The Dragon capsule has been designed from the start as a human-rated spacecraft. If all goes well, after a number of trial cargo flights, it’ll take over from the old Space Shuttles, to ferry US astronauts to the International Space Station.

Target: new worlds
There’s more - Elon Musk is thinking long, with eventual aims to shoot for the Moon and Mars. And a developed version of today’s Dragon capsule could make that first touchdown on the distant Red Planet.

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!

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