The Martin Marietta X-24A Lifting Body [IMG: NASA]
With the exception of the Space Shuttle, the high altitude flights of the X-15 and SpaceshipOne, all other human spaceflights have used capsules for reentry followed by descent under parachute. The capsule approach was originally adopted as the quickest way to get humans into space, but even during the 1950s other approaches were being considered – designs that would allow returning spacecraft a greater deal of control during reentry and more accurate landings than the first generation capsules could offer.
One line of thought centred around a vehicle that could generate lift via the shape of its body alone, a ‘lifting body’, and one of the most effective of the configurations that followed was the Martin SV-5/X-24. Continue reading →
When NASA pilot Bill Dana brought the X-15 to a halt on Rogers dry lake on October 24th 1968, it marked the end of the research plane’s flying career. At the time there were hopes that a final 200th flight could be made before the end of the year, but following a number of cancellations and aborts it wasn’t to be.
The X-15 programme drew to a close just as the world’s attention turned to the Moon with Apollo 8’s successful lunar orbital flight and the push towards a landing during 1969 to meet Kennedy’s goal. Continue reading →
By any measure the North American X-15 was an amazing aircraft. By the end of the decade long, 199 flight programme the three aircraft had pushed airspeed and altitude records way beyond all previous marks. Many X-15 pilots qualified as astronauts on their high altitude flights and the wealth of operational knowledge that was gained continues to influence aerospace programmes to this day.
Yet for all this, the X-15 is often overshadowed by NASA’s other activities during the 1960s and its legacy overlooked. It could never go as high or as fast as the capsules launched from the Cape, but the fact remains, at the time it was designed the X-15 looked like it would provide America’s first forays in human spaceflight and as Tom Wolfe points out in The Right Stuff, they would FLY their vehicle there and back.

The Space Launch System. The World’s most powerful rocket, getting ready to blast humanity into deep space and on our long awaited journey to Mars (or should I say #JourneyToMarsTM). Star of so many CGI animations and NASA presentations that I’ve lost count.
You’ve changed a bit since we first met – you used to look a lot more like the Saturn V, now you’ve shed the paint job and you look a lot more like a bunch of stuff from the Shuttle, but more of that later. See, the thing is I really, really want to see humanity go further into space and take a journey to Mars. I want to see a lander burrow under the ice and swim in the oceans of Europa, I want an incredibly advanced laboratory swooping through the plumes of Enceladus, I want a sub cruising the methane oceans of Titan – I guess I just want us to go places and do things. But SLS? I have my doubts. Continue reading →
Since the earliest days of the space age there has been something inherently attractive in the idea of a spacecraft that could glide back after its mission and land like an aeroplane. From Sanger’s Silbervogel onwards, a succession of spaceplanes sporting various shapes and configurations have flowed from the minds of aerospace designers.
Sierra Nevada Corporation recently announced that it is preparing its Dream Chaser spaceplane for a new round of flight tests. If Dream Chaser makes it into space, it will mark the culmination of a long evolution for a wingless ‘lifting body’ shape going back over 50 years and involving both Cold War superpowers…
I’m aware this is a definition that many may not agree with, but I feel it serves to frame the argument I wished to make. Please feel free to comment with your opinions, I’m happy to hear them just as you are giving me the time to express mine here! Continue reading →
May 5th 1961. As Alan Shepard soared into the Florida sky on a 15 minute sub-orbital flight, he flew into history, becoming America’s first spaceman. Freedom 7, as Shepard had christened his ship, was the opening manned flight of Project Mercury, NASA’s first foray into space.
