Heading into the Nullabor from Kalgoorlie, we ran out of paved road within about a half hour, but the road had a pretty good surface and surprisingly we could move at a pretty fast clip - until we popped a tyre.
No one other than Phil had experienced this while driving. When the tyre popped there was a slight pull, followed by a noise that sounded exactly like a 747 landing. We stopped and saw the very flat tyre. The hardest part was getting the spare off the roof, and the sandy ground didnâ€™t help. But in a bit we were on our way again â€“ until a tyre popped on the other car. In all it took about six hours to get to our first stop.
The next day, we headed off to camp further into the desert to begin our meteorite hunt, checking one of the cameras in the Desert Fireball Network on the way. The hardest thing when looking for meteorites is to get your eye acclimatised to the local rock types, so you can spot the meteorites â€“ rocks that donâ€™t fit in with the local rocks.
Caroline was the first to find a meteorite, within about 30m of the camp. We walked about another 2km before turning around, but didnâ€™t find any more meteorites, only kektites (pieces of glass from impactors that hit the Earth and launch molten earth rock into space, where it canâ€™t escape gravity and falls back down). We did find lots of â€˜meteowrongsâ€™ though, meaning we are recognising things that look a bit out of place but are the local rock!
The following morning was spent searching for meteorites systematically in a line. We went out about 1.5km before turning around and heading back to the cars. The whole thing took over two hours because we have to walk fairly slowly, but we did find several meteorites. Then, in the afternoon, we found more by going out in pairs and searching in a much more random pattern.
That night we had a fabulous dinner to celebrate Martinâ€™s birthday. The fridges weâ€™ve brought give us some opportunity to have fresh fruit and vegetables, and we had roast lamb, potatoes and onions. Delicious! The wind was blowing a gale and the clouds were gathering, which made eating the dinner interesting - we had five minutes to eat it while it was hot!
