I was 7 years old when Neil Armstrong stepped onto the surface of the moon. My parents were always strict about bedtime, especially when I had to go to school in the morning. This was the only exception that I can remember. Mum got us up at about 2 am to watch the landing live, and I’ve very grateful to her. “That’s one small step for a man, one giant…
Curiosity is safely down on the surface of Mars, and sending NASA low resolution images. Everything worked perfectly. She can now get on with finding out if Mars was ever friendly for life. The nerds just took gold in the 560 billion metres. La curiosidad esta viva sobre la superficie de Marte, y envíando imágenes de baja resolución a la NASA. Todo funcionó a la perfección. Ahora puede seguir adelante…

Mars is currently on the opposite side of the sun to Earth, and radio signals from Mars take 14 minutes to reach Earth. That’s far too long for the engineers at NASA to…
Sally Ride, the first American astronaut, died today at the young age of 62. She is survived by her partner of 27 years, Tam E. O’Shaughnessy.

The atmosphere is thin and dry, and the temperature drops very fast after sunset, so the snow flakes are tiny, about 7 microns in diameter, like a human red blood cell. In fact, it’s a lot like the diamond ice…

The island downwind of La Palma is La Gomera, 50 km away. I think it must have been early on Sunday afternoon: the fire in the west is out, and the clouds…
