Episode 35: 22nd July 2010: Dr Edgar Mitchell – Apollo 14

A man playing golf on the moon is one of the images permanently etched into the collective memory of humanity’s first exploration of the moon. The so called “golf player” was Alan Shepard the guy with him was Dr Edgar Mitchell whilst Stuart Roosa orbited the moon in the command module. Today, Ed Mitchell, two months away from his 80th birthday is the only remaining member of the Apollo 14 crew.

On a recent visit to Pontefract, organised once again by Ken Willoughby, he describes his personal journey to the moon. Amongst other things he highlights his javelin throw which, by a narrow margin, beat the golf ball, as a picture in his presentation illustrates. He spent nine hours on the surface of the moon during two EVAs on February 5th and 6th 1971. Apollo 14 was his only space flight and he left NASA in the following year.

Ed Mitchell is perhaps best known for his epiphany moment on the return journey to Earth when he experienced a unique spiritual sensation which has dominated his professional and personal life ever since. To help understand it, he left NASA and establish the Institute of Noetic Sciences. Over the last few years he has frequently spoken publicly about his interest in the paranormal, ESP and UFOs. He asserts that the Roswell incident was real, aliens have landed on the Earth and the US military is responsible for a cover-up.

It is strange that someone (a navy pilot and an Apollo astronaut) with a professional life dominated by leading edge science and technology can hold such an unscientific position. He appears oblivious to the contradiction in referring to himself as an astrophysicist and yet accepting Fred Hoyle’s Steady State explanation of cosmology, for which there is little evidence, over the Big Bang. I wonder how he explains Hubble’s law and the expansion of space, Cosmic microwave background radiation and the relative abundance of primordial elements.

I really should have asked him. I did not in part out of deference. Despite his age and unusual views, he remains a member of a unique group of individuals with a special contribution to human history. Who knows, he may well turn out to be right. In the meantime, the main road of science, directed by the sign posts of  observational evidence, is probably still the  best path to a more accurate understanding of the cosmos.

Dr Mitchell was kind enough to share his power point slides which I have incorporated into the hour long video presentation. Links to that presentation and a video version of this episode below.

An increasingly familiar quote from someone else who made a huge contribution to how we should go about understanding the cosmos. Carl Sagan.

I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence” .

Episode 34: May 31st 2010 Effelsberg Radio Telescope

Effelsberg Nestling in a valley amongst the rolling green hills of the Eifel region of western Germany is the 100m Effelsberg steerable radio telescope. Similar to the Lovell telescope at Jodrell Bank which is on the plains of Cheshire in northwest England which can be seen from miles away. The  Effelsberg telescope  is situated in a valley so it easy to pass close by and not see it.

It is an international facility. Participating in Very Long Base Interferometry (VLBI) where physical links are necessary with other countries it also hosts astronomers from many other countries  and participates in global research projects. Although its website may appear a littel dated, Effelsberg has a surprisingly rich online presence including the current schedule and of course the now mandatory webcam.

Effelsberg is a leading player in a new international project called LOw Frequency ARray or LOFAR.  Lofar targets the low frequency range between 10MHZ and 250MHZ. However, for many years commercial FM radio stations, the local emergency services and the aviation industry have been using frequencies between 90MHZ and 108MHZ so Lofar range is split in to two bands. Low (10-90MHZ) and high (108 – 250MHZ). Thus there are in fact three telescopes at Effelsberg.

On a recent visit, Dr Norbert Junkes talked about the previous, current and new activities taking place at Effelsberg.

 
 

Episode 32: January 1st 2010 Sir Patrick Moore

Patrick Moore and AmritaSir Patrick Moore is primarily known for his work on the long running TV series, The Sky at Night but he is an author, musician and an observational astronomer, too. He is also a former director of the Armagh Planetarium, a co-founder of the Society for Popular Astronomy and a former president of the British Astronomical Association.

His autobiography was published when he was Eighty in 2003. It is upfront, strongly opinionated, potentially uncomfortable in places for some and remarkably honest. He writes unapologetically with the political correctness of an earlier generation. He recounts his meetings with many of the key contributors in science and astronomy of the late twentieth century. It is a unique personal account of the development of astronomy and science during a fascinating period humanity’s exploration of space. An absolute “must read” for those of us who grew up with Sky at Night.

I met  Sir Patrick Moore at his home in Selsey, called Farthings, on 20th of August 2009. He was an extremely hospitable host. We discussed several themes of his autobiography Eighty Not Out, and we started with cricket.

=====================

Today’s quote, reflecting his tongue-in-cheek and humorous approach to to life, is from Patrick Moore himself.

At my age I do what Mark Twain did. I get my daily paper, look at the obituary and if I am not in there I carry on as usual.

Episode 26: Antikythera Mechanism

Everyone who comes across the Antikythera mechanism goes through a phase initially of disbelief and then the awe inspiring realisation that something almost from another world actually exists in ours.

Imagine William Shakespeare writing Hamlet using a laptop. Surely a ridiculous proposition he was about 300 years too early for that. He didn’t but today’s topic is just as incredible but thanks to the presence of physical evidence- true.

The bronze department of the Museum in Athens has a small device slightly bigger than a pocket dictionary which has spent 2000 years under the Mediterranean Sea. Its is a hand made hand operated mechanical mechanism which may have looked like a multi handed clock. This remarkably compact device can display the calendar, predict eclipses, illustrate the phase of the moon, indicate the position of most of the planets and even takes account of the precession of the lunar orbit. The mechanism is driven by a collection of precision gear wheels made in Greece about 100 BC and nothing like it would be made again for at least another 1000 years.

My thanks to members of the Manchester Astronomical Society who arranged this visit for Tony Freeth to come and talk to them, and Conway Mothobi of the Manchester Metropolitan University hosting the event where this recording was made. My thanks of course to Tony Freeth for making the time on the day.

Episode14:Titan

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.

 
 

Episode12:Journey to the Moon

Next year marks the 40th anniversary of Apollo 11 landing in the Sea of Tranquillity on the moon. In today’s episode – assistant director & co-producer Chris Riley talks about the recent film “In the Shadow of the Moon” which recounts that period and someone who was a part of it – astronaut Buzz Aldrin on his interest in Astronomy.

A short written account of his visit including a lunch with him and his wife is here.

 
 

Episode9:Early Astronomers

About 20 years after Galileo used the telescope for astronomy, William Crabtree and Jeremiah Horrocks used it to observe a transit of Venus in 1639. Carl Barry and Lilian Fletcher researched documented this unique event. If you missed it a 19mb video here.
Former executive Paul Allen (Allen Telescope Array) from Microsoft and Wayne Rosing (LSST Observatory) from Google are modern examples of private investors in space research.

Emerging from the the industrial revolution in the 19th century Lancashire were two similar individuals who contributed to making large mirrors and large telescopes. James Naysmith and William Lassell.
