Nov 1999
This month has not been the best week ever in the world of space and space exploration; it reads like one of those awful Monday "Shenzou"mornings that you get after that amazing Sunday night party which you can't remember much about. But at least it finished on a high note. The American X33 was an unexpected casualty, its new, amazing, high-tech, carbon fibre fuel tank split during testing. About the best thing that can be said is that it didn't split in flight, but I suspect it gives us a taste of things to come in this overly ambitious Space Shuttle replacement programme.
The Russians had a bad Proton launch (read BANG!) from Baikonur again, and so the Kazak government is presumably awaiting Shenzou (China's manned rocket) test launchsome kind of a deal with the Russians for compensation and has banned launches from the site once more. Hopefully the site will be able to launch the next stage of the International Space Station in February. Yes, February, all those shuttle delays last month with the faulty wires and some new ones found in the self-destruct devices for the solid rocket boosters have moved the timetable again.

China Reaches Out

The good news is that China have entered the space race in earnest, and that will start things moving again as the US gets scared. On 29th November this year, China launched its first unmanned, manned test flight as per the Chinese TV picture on the left. Unmanned in that there wasn't anyone home, but manned in the sense that the vehicle will be used for manned flight at some future date. The official details are that the CZ-2F launched the spaceship was named "Shenzhou" (that means "God Ship") from Jiquan Shenzou mission controland recovered it safely from Inner Mongolia after 21 hours during which time it completed 14 orbits. Not long now and we're going to be seeing "Taikonauts" up there as well as astronauts and cosmonauts.

I say it's good because the possibility of China being strong in space will spur the US and Russia into some rapid development work. China has realized that the country that gains and exploits space first will become the most powerful industrialized country on Earth, and very much wants the prize. We can expect to see an effort on behalf of the Chinese government nearly or perhaps more than equal to that of the enthusiasm displayed in the race to the moon. You can be assured that once China reaches orbit, it will not stop. Many observers will mistakenly think that this is a show by the Chinese government to bring attention to itself as a world power rather than a serious attempt at a manned space industry because the Chinese rockets are built using relatively low-tech designs, but forget that these are aimed at being working technology, not some kind of technology showcase like NASA.

The Hubble Space Telescope approacing the shuttleToil And Hubble

One of the Hubble Space Telescope's last essential gyroscopes finally failed, bringing observing to a complete halt. The thing isn't in any serious trouble, they just can't point it accurately anymore. Engineers have successfully closed the lid on the front to stop the sun shining in and fritzing the cameras, and it has been put on autopilot until the Shuttle can mount a rescue mission. It has plenty of steering fuel, and all systems except the gyros are operating normally. A full recovery is anticipated.

The service (now a rescue) mission will replace all six of the dodgy gyroscopes as well as beefing up the solar panels and replacing the cameras. The solar panels and cameras have been replaced before, but it makes sense to keep Hubble equipped with the latest observing technology.

Leonid meteorites over Spain (ESA)The Leonid meteor storm turned out to be more of a bit of drizzle for us Kiwis. The best view was to be had when we were on the other side of the sky, and every time I poked my bleary eyes out into the night I saw some most excellent cloud formations. OK, I saw one meteor doing about 72 Km per second overhead, but that was it. Even last year's "dismal" showing was better than that, although as the image (thanks ESA) shows, they had a better show in Spain. The best view however was had from one of two specially adapted USAF jets, which flew back and forth over the best bits of the show. I wondered if they guys up there felt the teensiest bit nervous.

Fairborn Observatory's T8 'scopeIt's A Bird! It's A Plane! It's ... A Planet?

On the plus side once more, a new planet has been detected around a star by measuring its light, rather than seeing how out of balance the central star is. This serious-looking telescope at the Fairborn Observatory, called the T8, confirmed that the light from a star called HD 209458 dimmed by 1.7% exactly when it was predicted that the planet would come between its sun and Earth on 7th November. In other words, we watched one of their solar eclipses to prove that the planet exists. One hopes they'll give it a more interesting name than its parent star, especially as we know more about it than any other extra-solar planet. We know how heavy it must be to cause the wobble in it's 3.5 day orbit, and we can now calculate how big it is by knowing how much light it blocks. So we know how dense it is too. It's bigger but lighter than Jupiter and going round awfully fast - Jupiter takes 11.8 Earth years to do an orbit.

It's clear that the planet could not have formed where it is, but must have been captured and dragged in, say observers. But, recent evidence from the Gallileo probes dropped into Jupiter show that there are too many gasses on Jupiter for it to have formed so close to our sun. So is it possible perhaps that it is common for large planets to form far away and be attracted in by their sun? It's amazing the questions that can be brough on by watching a star flickering 51 lightyears away.
