Methane on Mars

I was very excited to read about the discovery published last week by NASA’s Curiosity rover of the seasonal variation in the amount of methane in Mars’ atmosphere. Curiosity found that the average methane concentration varied from 0.24 parts per billion (ppb) in the northern hemisphere winter to around 0.65 ppb in the summer. This… Continue reading Methane on Mars

American manned spaceflight in 2018?

As readers of a previous post will know, since the retirement of the Space Shuttle in July 2011, America has been unable to put any astronauts into orbit around the Earth. Instead, it has been reliant on the Russian Soyuz spacecraft to ferry astronauts to and from the International Space Station (ISS). This situation may… Continue reading American manned spaceflight in 2018?

A Christmas gift from The Science Geek 2017

"Is Anyone Out There?" is about the likelihood of there being extraterrestrial intelligent life.  It is based on a number of posts from my blog.  For readers based in the UK the… Continue reading A Christmas gift from The Science Geek 2017

The early days of the space race

In my previous post I talked about two significant successes for the Soviet Union in 1957: the first artificial satellite in orbit in October and the first living creature, a dog named Laika, in orbit in November. In December of that year the Americans had a humiliating failure when the Vanguard spacecraft exploded in a… Continue reading The early days of the space race

4 October 1957 – the start of the space age

Exactly sixty years ago today, on 4 October 1957, the Soviet Union launched the first artificial satellite, Sputnik 1, into orbit around the Earth. This is considered to be the beginning of the space age. Before this date there were no man made satellites in space but on every single day since then there have been… Continue reading 4 October 1957 – the start of the space age

Enceladus -Could there be life?

Three years ago my first ever post was about Saturn’s moon Enceladus. It is interesting that once again this small moon is in the headlines as a possible place on which there could be life.

The Science Geek

Welcome

Hello and welcome to the first post from the Science Geek 01. I intend to write  a weekly blog about various topics of interest, which will cover all aspects of science. The articles will be aimed at the non scientist and won’t require any previous detailed knowledge. I hope you enjoy reading them and please feel free to comment.

My first posts will deal with the subject of life within the solar system, which in astronomical terms is our own backyard.

Life on Mars

Throughout most of the twentieth century many scientists thought that there could be life on Mars. Indeed the famous American astronomer Percival Lowell (1855-1916) claimed to have seen through his telescope  a large network of canals built by an intelligent civilization  and even produced maps of the Martian canal network. These  canals certainly provided great material for science fiction writers but they were probably all due to Lowell’s imagination!
