Episode14:Titan

By Gurbir Dated: May 6, 2008 2 Comments

After a 7 year journey, Cassini/ Huygens arrived at Saturn in 2004 and Huygens landed on the surface of Titan on January 14th 2005. The only moon within the solar system known to have a substantial atmosphere.

On Monday 3rd of July 1989 it was possible to study the atmosphere of Titan from here on Earth when it occulted a 5.8mag star 28 Sagittarius. Ken Irving from Salford Astronomical Society describes the observation he made and video recording of the unexpected central flash. Available below.

Using data from the onboard Acoustic Sensor Unit, the Planetary Society compressed Huygens two and half hour descent into a 10 second audio clip.

After landing, Huygens continued to transmit data including those incredible pictures of the surface for another 70 minutes until the communication link to Earth – Cassini disappeared over the horizon. It would not come in range again for 40 days by when Huygens’ batteries were dead. There in its dark cold -180C deep freeze it remains. Probably intact. Professor John Zarnecki from the Open University who lead the Surface Science Package team talk a little about the achievements f the Cassini/Huygens mission.

Episode13:Rockets

By Gurbir Dated: April 27, 2008 1 Comment

You may have seen the report from the British UK Space Exploration Working Group suggesting that Britain can get two British Astronauts to the Space station costing less than £75m over 5 years by commercially engaging the Russian Soyuz program rather than the annual £60m cost of going with ESA, or indeed developing a British launch capability.

The Astronomer Royal on the other hand insists that unmanned space research is the way to go. You get a heck of a lot more science for your money

Dave and Leslie Wright from the British Rocketry Oral History program (BROHP) reminisce about the early days when Britain had its own launch capability and the UK Space conference that they host each year.

Want to be a rocket Scientist? Well a new book from a rocket scientist Lucy Rogers may be a good start. Lucy is also the chairman of the Vectis Astronomical Society on the isle of Wight. Their website must be one of the most elaborate. Check it out but .. turn down the volume on your PC first.

Its that time of year. Summer time has arrived but not yet.. the summer. Local astronomical societies all over the country are winding down from the previous season and preparing for the next. In today’s episode a little more about two individuals who have been on the speaker list for many astronomical societies. Martin Lunn from Aurora Books and Andy Lound from Odyssey Class Dramatic lectures.
