My Life on Mars: The Beagle 2 Diaries by Prof Colin Pillinger.

First of all, please bear in mind that it has taken me quite a while to read this book – I’ve been rather busy over the last few months with OU studies and so on.

I was 13 on Christmas Day 2003, when Beagle 2 was due to land on Mars. I had got up extra early to pop and the news and see what had happened. It wasn’t good news.

Since then though I have always been astonished that we actually sent a mission to land on Mars, we the British people had made a lander to look for the signs of life on another world. I needed to know how it was done – finally Colin’s book came out.

It’s quite an intense book, there’s a lot of information, a lot of names to follow. I found at times that this made it slightly difficult to read, having to head back a few pages to figure out which person was being discussed now. I understand that in a project as grand as this a lot of people are involved, and at the end of the day the story needs to be told.

In this book we learn about Colin’s family history, his youth, how he became interested in science and eventually how he sent a lander to Mars. I had no idea how difficult it could be. The meetings, the letters, the phone calls, the arguments. I was very surprised about the European Space Agency, this book has changed my opinion of them, and not in a good way. Infact near the end I quite liked this quote regarding ESA ‘The way things are going the Universe will end before ESA arrives on Mars’, this referring to their Aurora programme.

If you’re interested in space exploration and want to understand how a space mission works and is put together this is a must read. It had me laughing and gasping in shock, you’ll enjoy it.

It’s 4 out of 5 from me!

Next book – The God Delusion by Prof Richard Dawkins (finally!)

A New World – Dawn approaching Vesta

Dawn – The journey to the beginning of the Solar System! It’s a fairly ambitious mission, as are most of NASA’s missions at the moment. Firstly the spacecraft uses ion propulsion, a technology tested on Deep Space 1 but never before used for a dedicated science mission. Secondly Dawn has not one but two targets. The large asteroid or even protoplanet, Vesta and then the dwarf planet Ceres. The spacecraft will go into orbit around Vesta, happily do some science for a while, break orbit and then go to orbit Ceres!

Launch of Dawn on a Delta II Rocket

Dawn launched back in September 2007 atop a Delta II rocket. It’s been in the cruise ever since, giving short bursts of ion propulsion to refine it’s orbit. Now after nearly 4 years she’s almost arrived, ready to hop into orbit.

Vesta is the largest asteroid in the Solar System (Ceres is larger but is termed a dwarf planet) it’s about 530km across and is estimated to contain 9% of the mass of the asteroid belt, so it’s a pretty hefty object. It’s thought to be differentiated, that is it’s so big so that heavier elements, like iron, fall towards the centre and lighter elements are found nearer the surface. This is the same way that Earth’s core formed.

We already know a fair bit about Vesta surprisingly. About 1 billion years ago Vesta was hit by an asteroid that’s left a small crater. This threw out lots and lots of debris, and quite a bit of this has fallen to the Earth. These meteorites have the fancy name of Howardite-Eucrite-Diogenite (HED) meteorites. Evidence from these meteorites show that Vesta is between 4.43 and 4.55 billion years old and reveals that Vesta has a history of extensive igneous processes. Infact the meteorites are very similar to magmatic rocks found on the Earth.

The mission at Vesta is to develop our understanding of how the Solar System formed and in particular what role water played in planetary evolution. Vesta and Ceres both reflect what the early Solar System was like, something we can’t figure out here on Earth because of all the geological activity the Earth is still going through.

Return to Tempel 1

The American’s have hyped this up a bit, ‘Valentine encounter for Stardust and comet’ when strictly speaking (if you follow GMT/UTC) then it’s the day after valentines. But hey, I guess if it gets people interested, why not.

Impression of Stardust-NExT's encounter with Comet Tempel 1

The Deep Impact spacecraft originally flew past the comet back in July 2005 and launched a projectile at the comet. Continue reading
