This is an ‘html-only’ version of Scribblings with no database behind it. This means it is not possible to search it. I am working on a new version with which I am hoping to eventually put back into the main site. The new version is here but please note that there is no link directly back to the main site.

Bicycles and space travel
We have a NASA astronaut visiting the school next month and I plan to ask him a question about the perceived dangers of travelling in space. I’m sure he knows the facts but I’d like to know just how dangerous it really feels.
Looking around the Internet has revealed that since Yuri Gagarin first went into space in 1961 there have been 18 deaths which have happened on actual missions1 while considerably more have died on the ground2. I have been unable to find an exact figure for the number of people who have been into space but various sources say it is around 400. Thus of all the people who have flown in space about 4.5% have been killed, a figure which in most other walks of life would be unacceptably risky.
I plan asking our visitor just why he and his colleagues continue to fly if they know the risks are as high as they are, as they most surely do. To put it into a context which our kids might possibly be able to relate to I’m going to ask him which would feel most risky to him: travelling in space or riding a bicycle on a motorway.
1 A Russian cosmonaut died in 1967 when his parachute failed to open before landing; three Russians died in 1971 when their capsule depressurised during re-entry; seven astronauts died in 1986 when the shuttle Challenger blew up just after take off and seven more died in 2003 when Columbia broke up on re-entry.
2 91 people died in Kazakhstan in 1960 when a rocket exploded; 50 died when a Vostok booster rocket blew up while being refuelled in 1980. There have been numerous smaller accidents including the fire on Apollo One in 1967 which killed three astronauts on the ground.
An apology
Since moving the site to a new server Scribblings is not as easy to find your way around as it used to be. It used to depend on a script and a database on the server but is currently served as ‘flat html’.
I have some ideas about how to make it a bit easier but they depend on writing another script. I hope to get around to it ‘eventually’.
