Jupiter’s Great Red Spot was discovered by the English scientist Robert Hooke in 17th century. It lies very close to the giant planet’s equator and its major axis is 40,000 km (twice the diameter of the Earth. We now know that it’s a hurricane, which rotates anticlockwise with wind speeds around the edge of up to 400 km / sec. Photo taken by NASA’s Voyager 1 space probe.
This wonderful photo of Saturn was taken by NASA’s Cassini mission on Sept. 15, 2006. The sun is behind the planet, giving a wonderful view of the rings. Even more spectacular, you can just see the Earth at the left.
The Mars rover Curiosity is driving over a dried-up stream bed. Looking at the gravel under Curiosity, NASA scientists say the water must have flowed about 1 m/s and been somewhere between 10 cm and a metre deep. That’s a lot of water, although it was probably billions of years ago.
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…
Curiosity, also known as the Mars Science Laboratory, will touch down on Mars at 6:31 (BST or La Palma local time). I hope it won’t crash into Mars hard enough to create a new impact crater. 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…
