There must be something going on between Space Exploration Technologies (SpaceX) and NASA with this coy reply from SpaceX

We are currently reviewing the proposed procurement (its terms, scope, and duration).  We are interested, as you know, in providing a domestic alternative to having NASA purchase Soyuz to carry US astronauts to and from the ISS.

in response to an email of mine enquiring about this interesting development with NASA’s International Space Station crew transportation arrangements being opened up

Why must it be SpaceX? Well its only other competitor in the whole Commercial Orbital Transportation Services (COTS) and Commercial Resupply Services (CRS) programmes is Orbital Sciences and its Cygnus spacecarft is strictly for cargo

PlanetSpace just had its protest against Orbital winning that CRS contract denied and its partners included Lockheed Martin, Boeing and Alliant Techsystems

With all the kerfuffles early last year about Lockheed Martin/United Launch Alliance Atlas V’s being used for some sort of transportation system those companies are saying little – in fact one notable aspect of the Space Foundation’s 25th National Space Symposium was how low key the big primes were playing the Constellation programme. Unless you asked specifically about it there were no Constellation dedicated briefings to attend

And the Europeans and the Japanese are a long, long way from producing anything crew related, so scratch that non-Russian foreign option

So that leaves SpaceX. Hyperbola hopes to speak to NASA soon for more info…
