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 →
SpaceX’s next Falcon 9 launch, possibly as early as March 29th, will mark a major milestone for the company. Carrying the Luxembourg owned SES-10 communications satellite, it will be the first to reuse – and hopefully recover for a second time – a previously flown Falcon 9 core.
Since the first successful Falcon 9 landing on December 21st 2015, SpaceX have repeatedly demonstrated the ability to recover their first stages to both downrange droneship and Return To Launch Site pad landings. But while there can be no doubting how technically impressive this capability is, it will ultimately count for nothing unless they can refurbish and re-fly the recovered cores repeatedly, amortising their development costs and sustaining reduced launch costs for their customers.
SpaceX had originally hoped that this flight would take place in 2016, but that was before the launch pad explosion of a Falcon 9 carrying the AMOS-6 satellite during a static-fire test on September 1st, 2016. Since Falcon’s return to flight in January this year, the company are pushing hard to regain lost ground across a number of fronts. Continue reading →

Few sights could be more synonymous with the space age optimism of the 1960s than the mighty Saturn V. Built to take Americans to the Moon at the culmination of a politically fuelled space race, it also represented the ultimate expression of von Braun’s long held desire to use rocketry to reach other worlds. But while the Saturn V is deservedly honoured for its historic role, much of the work to make this success possible was carried out during the development of its smaller, less well remembered predecessor – the Saturn I.
Often consigned to the footnotes of space history the Saturn I story began well before Apollo, the programme that provided its defining role. Saturn I’s early development spans the military power struggles of the pre-NASA age and indeed its development helped bring key capabilities to the nascent space agency that remain important and controversial to this day. Although understandably overshadowed by the mighty Saturn V, for a while it looked like the Saturn I and subsequent variants might become among the most important workhorses of America’s expansion into space, a flexible and ubiquitous launcher with a life way beyond the lunar landings. Unfortunately, as with so many of the ambitious plans of the 1960s, the Saturn I never fully realised this potential. Continue reading →
Recently I returned from a trip to California. While this was a family vacation, it did give me the chance to visit some fantastic space and aviation related attractions reflecting the state’s rich aerospace heritage. Here’s a quick roundup of what I saw… 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…
Few spacecraft are quite so instantly recognisable as the Shuttle Orbiter. Even in retirement the surviving craft remain iconic, resplendent in their black & white thermal tiles and boasting their trademark double-delta wing.
But the story of how the Orbiter got its familiar shape and the Space Transport System reached it’s eventual configuration is an interesting one reflecting the requirements of the US Air Force more than the needs of NASA. So why did the Air Force have such a big hand in the design and what were their plans for the Shuttle? The story starts in the Apollo era of the late 1960’s. Continue reading →
