Chance encounter with a 'rocket man'.

PictureWalking the Pembrokeshire Coastal path (SW Wales, UK).
Firstly, let me apologise to those who follow this blog for not posting recently, especially as so much is happening - in particular the Rosetta mission saga!

A combination of circumstances have inhibited my blogging activity - a hardware problem with my laptop in August followed by a couple of holidays in September.  I am hoping to make up for the deficit in the coming days, but let me say something about my recent holidays - bear with me - it does have some relevance to 'space'. 

In early September we took a break, walking the beautiful coastal path around Pembrokeshire in SW Wales.  The picture above shows a section of the route near St David's Head.  It was sensational weather for this part of the world, with beautiful settled sunny weather every day during our week's break.  Since I am quite fair skinned I definitely had to take precautions not to burn while out all day in the sun, and this included wearing a sunhat.  The only one I had was a  NASA baseball cap given to me by an American friend who was visiting the Ames Research Centre in the US.  So as my wife and I were taking a rest and some food, another couple wandered by.  The gentleman, clearly american, asked about the NASA cap and we struck up a conversation.   Turns out he worked for NASA as a rocket engineer, being responsible for the Space Shuttle Orbital Manoeuvring System (OMS) engine before the shuttle's retirement in 2011.

PictureThe other holiday break was to the N Devonshire coast, near Lynton UK.
Now he was working on the plan to adapt the OMS engine for use on the new US manned vehicle Orion.  In particular, the current plan is to use the European Automated Transfer Vehicle (ATV) as the Service Module for the Orion capsule, and my newly acquired friend's job was to look at the possibility of integration of the OMS with the ATV - see picture below of the proposed new manned vehicle.  What are the chances of such a meeting in such an unusual setting?!  Anyway needless to say we struck up a very interesting conversation, much to the amusement of our respective wives.   And to add to the long odds, we walked in widely separated locations on the coastal path each day, but somehow we managed to bump into each other on three separate occasions during the week.

We both lamented the current state of the US human spacecflight programme, with US astronauts dependent upon Russian goodwill for access to orbit.  And with the current situation in the Ukraine, and the downing of flight MH17, relations with Russia have been stretched almost to breaking point.  Since the retirement of the Shuttle, and the cancellation of the Ares launcher programme by the Obama Administration, US astronauts have had to hire a ride (at a rate of around $60 million/seat) on the Russian Soyez spacecraft.   The US Administration has also proposed extending the lifetime of the International Space Station (ISS) to possibly 2026 (hopefully the US will have an independent means of human access to orbit by then!).

The collaboration between the USA and Russia has been a very healthy one over the years, especially with the establishment of the ISS.  However, this relationship is not just a collaboration - the USA also depends upon Russian space technology in other ways.  For example, the USAF launches classifed payloads (intelligence spacecraft) using Atlas V launch vehicles, which are powered by Russian RD 180 rocket engines.  At the moment there are around 15 of these Russian engines in the american stockpile, and if Russia places an embargo on their future export there could be a few red faces in the US Intelligence Agencies.  Curiously, the US needs Russian technology to spy on Russia!

Time for the Obama Administration to wake up I think, and implement a space strategy that actually makes sense.
