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 →
As NASA came to grips with the enormity of the task handed to them by President Kennedy in his May 1961 congressional address, the list of hurdles standing between America and a manned moon landing was long and formidable. Although NASA’s senior management felt confident that the task could be accomplished before the end of the decade, the finer details of how this would be achieved were far less certain.
Much of the initial focus of Project Apollo fell on the fundamental question of which mission mode should be employed. Some favoured Direct Ascent – launching one huge spaceship directly to the Moon where it would land before returning to the Earth. Others argued Earth Orbit Rendezvous was far more achievable given the limitations of American rocketry at the time. A third group suggested Lunar Orbit Rendezvous may hold significant advantages, but all three approaches had one thing in common – they would involve the controlled landing of a spaceship subject to the Moon’s reduced gravity and lack of atmosphere.

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 →
With hindsight, it is now popular to view the Space Shuttle as a flawed concept, born out of political compromise and budget constraints. Never able to maintain anything like the original projected flight rates, hugely expensive and time consuming to maintain, the shuttle can seem like something of a developmental dead end or, as some have claimed, proof that reusability can never be economically viable.
As we enter an era where both SpaceX and Blue Origin aim to prove that Vertical Takeoff/Vertical Landing rockets can offer a sustainable route to Earth orbit and beyond, it’s interesting to look back at a reusable spaceplane concept that predated NASA’s shuttle studies and could, had things been different, have ended up being America’s national launch system from the 1970s onwards. But this is also the story of the man behind the concept, Max Hunter, a visionary who – along with contemporaries such as Philip Bono (see more on Bono’s SSTO designs) – helped define the desirability of reusable launch vehicles at a time when the world was still focused on the short-term spectaculars of Apollo’s race to the Moon.

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 →
Having recently read Safe Is Not An Option, I started out intending to write a review of the book but decided to expand that out to capture some thoughts on the subject at greater length.
Firstly I think its worth noting the book’s full title – Safe Is Not An Option: Overcoming The Futile Obsession With Getting Everyone Back Alive That Is Killing Our Expansion Into Space. So a pretty uncompromising introduction right there on the cover, but any serious discussion on this subject needs to confront the subject head on and challenge our preconceptions and Simberg certainly doesn’t dodge that challenge. So why the need for this seemingly iconoclastic viewpoint? Continue reading →
“Beware of the bull. He will carry you safely anywhere that you have to go and protect you from any enemies. He is awesome in battle. However, if you lose control of him or fall off, he will kill you as quickly as he would kill your enemy”
from At the Edge of Space – Milton O. Thompson
On 8th June 1959, Scott Crossfield dropped away from beneath the wing of the B-52 carrier aircraft in X-15-1 and made a relatively uneventful glide back down to Rogers Dry Lake. During the brief flight, the sole planned glide flight of the entire programme, Crossfield allowed himself an aileron roll, all the better to check the new aircraft’s handling. Unfortunately his first landing was far less enjoyable with the X-15 bucking wildly as he struggled to put it down on the lake. The source of the control problems was soon isolated and fixed and the X-15 moved forward on its mission to unlock the secrets of high-speed, high-altitude flight. Continue reading →
