Episode 28: Apollo 13

By Gurbir Dated: July 21, 2009 Leave a Comment

On this day 40 years ago the crew of Apollo 11 fulfilled one of mankind’s longest held dreams and walked on the surface of the Moon. One of them Buzz Aldrin in episode 12 of ATUK, recalled a little of that experience.

Today’s episode is a short recording with Fred Haise when he visited Pontefract as arranged by Ken Willoughby. Incidentally, Jim Lovell is also visiting Pontefract in Yorkshire on October the 2nd 2009. If you are close to northern England on that date consider stopping by. Of the twelve men who walked on the Moon only nine remain.

Apollo 13 astronauts Fred Haise along with Jim Lovell and Jack Swigert were arguably the subject of the 20th century’s most dramatic events and the subject of the film Apollo 13.

Fred Haise never made it to the surface of the Moon.

He served on the back-up crew for the Apollo 8, Apollo 11, Apollo 16 moon missions and was also scheduled as commander for the cancelled Apollo 19 mission. As a backup he could have been on the first mission to the moon (Apollo 8), first moon landing (Apollo 11) and of course commanded his own mission on Apollo 19 but the Apollo program was cancelled after Apollo 17.

Remember the first Shuttle – Enterprise, on the back of a modified 747? Between February and October of 1977 it flew 16 times to perform the approach and landing test of what would become the Shuttle Transport System which is due to conclude next year 2010. Fred Haise was involved in 5 of those. Three of which involved the Enterprise in free flight.

When I spoke to Fred during the dinner on the day before this recording, he came across as an ordinary guy who did not consider himself to be “special” but just around in the right place at the right time. During the course of the evening he spoke to many who were present but most of the evening had gone by and I had not had a chance to say hello. Then suddenly he approached from a corner of the room and said “Hello, I’m Fred Haise, I don’t think we’ve met”. In the short conversation that followed he indicated that fishing was his primary hobby and although his trip aboard Apollo 13 was dramatic he had an eventful life before and after it too.

Sure, it is impossible to have a deep insight from a couple of short meetings. Perhaps, it was the ease with which he used my first name (which some people find heavy going) and conversed as if I had always known him. There was something special about the ordinary way he conducted himself. He had accepted the extreme high and low experiences in his life as nothing more than an occupational hazard. Apollo 13 as the only space flight he ever made.

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

This week’s quote is from Carl Sagan

There are many worlds we have never seen before. Only one generation in the history of the human species is privileged to live during the time those great discoveries are first made; that generation is ours.

Episode 26: Antikythera Mechanism

By Gurbir Dated: June 28, 2009 2 Comments

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.

Episode22:Interstellar Dust

By Gurbir Dated: July 13, 2008 Leave a Comment

As episode 21 indicated, the power of science fiction to motivate the imagination is perhaps as strong as science itself.

1957 is known for the launch of Sputnik but it was also the year that the scientist Fred Hoyle published a science fiction novel called The Black Cloud. One of its readers in Italy would be inspired by it to  become an astronomer and embark on a career which involves the scientific study such clouds.

Professor Paola Caselli was that reader and since the autumn of 2007 has been the professor of Astronomy at the University of Leeds where Fred Hoyle had been a student. Her area of interest is the study of those regions of space of dust and gas (“dark clouds”) from which stars and planet eventually form.

Dust comes in many forms – cosmic, cometery and interplanetary dust which is responsible for the zodiacal dust we can see from Earth. Professor Caselli investigates cosmic dust grains (atoms or molecules of Silicon, Magnesium, Carbon and others) which act like magnets and help suck out the volatiles from a dust cloud in the early stages of star formation. Some of these process are probably taking place right now in the recently announced discovery of HL Tau and its associated proto planet HL Tau b.

She will be speaking on “From Interstellar Clouds to Planets: the Universal Factory“at the now famous, Leeds Astromeet on Saturday 15th November at the University of Leeds.

Episode21:Science, Science Fiction and Astrobiology

By Gurbir Dated: June 28, 2008 Leave a Comment

Professor Mark Brake from the University of Glamorgan has an eclectic interest. An academic, broadcaster and author of science and popular science books, he is the organising chair for the the third conference of the Astrobiology Society of Britain: ASB3: The Living Universe, will take place in Cardiff between July 1-4, 2008. We spoke about the relationship between science & science fiction and astrobiology.
