The other bit of creative licence was the sequential swinging away of the gantrys at launch.

Did you spot the deliberate mistake near the beginning?
While Armstrong/Aldrin/Collins are at the Moon, the other astronauts are having a party. Jim Lovell (Tom Hanks) is out in the garden looking up at the Moon, which is almost 'full'. In reality, when Armstrong et-al were there, the Moon was only a crescent. Apparantly, the film-makers deliberately had an almost full Moon for that shot, because if you ask people old enough to remember Armstrong's first Moonwalk, they almost always think they remember the Moon as being full (or pretty close to full) Andrew Smith also mentions this phenomenon in his book 'MoonDust'. Personally, I think people must have been looking at the Moon in wonder, AFTER the landing, and that's the image they remember and assosciate with the landing. (It would be 'full' about a week after Armstrong and colleagues got home) I do remember looking at the moon on the night of Saturday 19th July 1969 and it was a crescent as it was for most of the Apollo landings. Apollo 12 had the largest moon phase as it was the most westerly landing on the face of the moon. All the landings were arranged so that the sun was quite low in the moon sky. I presume that was to reduce the need for cooling the spacesuits. |

There's a 4 page article about it in the June issue of 'Astronomy Now' magazine.

Andrew Smith on page 20 of his book describes the moon as "a big silver full Moon". Not sure if he mentions it anywhere else but his memory was clearly mistaken.

As previously mentioned he does indeed talk about this full moon false memory syndrome.

Thank you. I guess there will be articles in all the major astronomical magazines.
![]() Just picked up the June edition of 'Sky at Night' mag - there's a Tunguska article in there too. Haven't read the S@N article yet, but the Astronomy Now article concentrated quite a bit on lake Cheko (8 miles NW of the blast's epicentre), and conjecture as to whether or not it was created by the impact. Lake Cheko doesn't appear on any maps that pre-date the blast, but that in itself doesn't mean a lot when talking about maps of a remote area, made before 1908. It is NW of 'ground zero' (the explosion actually occurred between 5 and 10 miles altitude), and the projected trajectory of the meteor was NW. The lake is oval though - whereas meteor craters are usually circular, unless the meteor comes in at a VERY shallow angle. A group of Italian scientists have been up there last year, and are returning soon to make further tests - Reading between the lines, it appears that the Italians seem to think that despite the anomalous shape of Lake cheko, it may well have been excavated by material that continued on North-westerly, after the blast - or maybe that the meteor broke up before the main blast, and some fragments may have excavated Lake Cheko. |

Well I got bored with his book and never read it to the finish.
I'm still waiting on recommendations for books about Mercury and Gemini! |

Look out for the articles stating that if it had happened hours earlier/later (they are never too sure) it would have wiped out St Peterburgh. Well I guess if it had been hours earlier or later it would have missed the earth completely.

The Phoenix spacecraft is due to land on Mars in the very early hours of Monday our time.

This time, NASA's using retrorockets to slow things down rather than the blown-up Tesco bag system that they've recently been using to land probes. I hope it succeeds and gives us information about soil composition and permafrost ice content but we'll have to wait and see. Something like two-thirds of all Mars missions have ended in failure. By the way, I can highly recommend Laurence Bergreen's The Quest for Mars about the inside story of recent American Mars explorations and, best of all, it's only 99p (hardback) from my local The Works bookstore. |

At last - success! The pictures from Phoenix have revealed a cold, dusty and stony ochre plain. It seems from the pictures that cycles of freezing and thawing have been going on to give the distinctive polygonal structures that we also see in Earth's arctic (see here at http://www.athropolis.com/arctic-fac...t-polygons.htm).
In a few months' time, poor old Phoenix will be frozen and buried under a layer of ice and I hope the mission yields some useful results. |

Pictures of the analemma of the sun are very rare....the first ever being made in 1979. Now someone seems to have doubled the quantity.
See http://perseus.gr/Astro-Solar-Analemma.htm |

Proposed European manned space module. It's based on the Euro space truck. France, Italy and Germany want in. I think we'll join eventually since we've signed up to the Euro astronaut training programme and our hi-tech industries think there's lots of economic benefits from being part of the consortium.

...and after that you can watch the shuttle launch. Nice bit of scheduling
