Rosetta & Philae? It’s all about the feels!

Rosetta & Philae – A Hero’s Journey for our generation [IMG: ESA}
When the European Space Agency (ESA) Rosetta spacecraft set down on comet 67P/Churyumov-Gerasimenko on September 30th 2016, it marked the official completion of a 12-year mission covering almost 8 billion kilometres. Whilst analysis of the data returned by Rosetta and its diminutive lander Philae will continue for decades, the journey is at an end for two beloved social media personalities spawned by the mission, for as tough as chasing down a comet may be, the Rosetta team had another objective that seemed almost as elusive – how to re-engage the interest of the general public following Rosetta’s lengthy hibernation and communicate the mission’s key goals and context.

An Aerospace Roadtrip

NASA Shuttle Carrier Aircraft N911NA on display in Palmdale [IMG: Chris Petty]
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…

The Sunnyvale Shuttle: Lockheed’s STAR Clipper

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.

The final steps and legacy: The North American X-15 – Part 3

The proposed Delta-Wing conversion was just one of many X-15 follow-on projects discussed during the programme [IMG: NASA]
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.

Thoughtful Courage or Fearful Safety? Thoughts inspired by ‘Safe Is Not An Option’ by Rand Simberg

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?

Riding the Bull: The North American X-15 – Part 2

“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.

Toward the Unknown: The North American X-15 – Part 1

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.
