Episode 58: Astronauts Joe Engle and Ron Garan

By Leave a Comment

Joe EngleThe first  interview in this episode is with astronaut Joe Engle was recorded during his visit to the UK in 2008.   Joe Engle was at the front of the queue  to go to the Moon when NASA cut its Apollo program. His place was taken by the geologist Harrison Schmitt on Apollo 17 – the last manned mission to the Moon. In this interview Joe talk about his work before and after Apollo – on the X-15 and Space Shuttle programs.

The second short interview with astronaut Ron Garan was recorded at TedXSalford in January 2012 (unfortunately the recording stopped prematurely).  You can see more about the online community offering a “unique orbital perspective of men and women who live and work in Space” online at Fragile Oasis.

Episode 55: 4 August 2012: Mars Curiosity Rover

By Leave a Comment

Since the mid 1970s six spacecraft (Viking 1 & 2, Sojourner, Opportunity, Spirit and Phoenix)  have successfully landed on the surface of Mars. In probably the most audacious, breathtaking and risky space missions, in less than two days, another  Mars Curiosity Rover will arrive on Mars. Using a technique never used before, NASA has described the Entry Decent Landing as the seven minutes of terror.

Launched in November 2011, the arrival of Mars Curiosity will for the first time make a high precision landing which is so crucial to its primary scientific goal of finding evidence of earlier Martian environment that may have been suitable for life.

Also known as the Mars Science Laboratory (MSL) it will be supported by a pair of NASA satellites (Odyssey and Mars Reconnaissance Orbiter (MRO) already in Martian orbit. Mars has never been under so much human scrutiny. In addition to the still functioning Opportunity, a rover on the surface of Mars (launched in 2004) and the two NASA satellites, there is also the European Space Agency’s Mars Express is also in Martian orbit.

Dr Anita Sengupta is a member of the Entry Decent Landing and Advanced Technologies group at Jet Propulsion Laboratory. In this interview recorded on August 2nd via telephone from her office in JPL she captures the sheer exhilaration of the dramatic entry decent and landing phase  and describes her role in the Mars Curiosity rover mission.

Episode 50: 26th March 2012: Manchester first Rocket Scientists

By 1 Comment

27th March 1937 - Foreground (left to right): Eric Burgess, Bill Heeley, Trevor Cusack, Harry Turner (Picture – Philip Turner)

Robert Goddard in America , Sergei Korolev in the Soviet Union and Herman Oberth in Germany are three names credit with the development of rocket propulsion during the late 1920s and early 1930s. Each led a very small group with more dedication then resources working on a shoestring budget usually in their own time after work. Their collective work eventually lead to Sputnik, the space race and one of mankind’s greatest technological achievement – Apollo 11 mission to the Moon in 1969.

During the inter war years, the northwest of England gave rise to organisations that nurtured the science of rockets and space travel. In 1933, Philip Cleater in Liverpool founded the British Interplanetary Society (BIS) to promote spaceflight, an institution which continues to exist to this day. A little known group established in 1936, called the Manchester Interplanetary Society (MIS) shared the lofty idea of space travel and had the ambition and talent to design, build and test rockets that could help to realise it.

The MIS founded by an ambitious and gifted sixteen year old Mancunian Eric Burgess in 1936.  Initially, Burgess used his own home, 683 Aston New Road as the headquarters but  moved to a founder member, Harry Turner’s house in Lonsdale Place not far Manchester City centre in the following year. Arthur C Clarke a member of both the science and sci-fi communities visited Harry in Manchester several times and promoted both.

Clayton Vale, a stone’s throw from the velodrome in East Manchester, is now a small picturesque park with the river Medlock running through its length.  On Saturday 27th March 1937 it was more of a slag heap for the nearby coal mine and local industry and a site used by the Manchester Interplanetary Society (MIS) to test launch rockets made by its members. Following five largely unsuccessful cardboard rocket launch attempts the sixth constructed from aluminium exploded injuring three, one requiring hospital attention.  The event was heavily featured in local and national press. Malcolm Wade, the MIS secretary said in the 29th March 1937 edition of the Daily Herald “If only the crowds had remained at a proper distance during Saturday’s trials instead of hustling around us, there would have been no accident.”

Most of the active members of the MIS received a summons to appear at the City Police Court on May 14. The charge against Harry Turner was that he “unlawfully did manufacture a certain explosive you not being allowed by section 4 and 39 of the Explosives Act, 1875 to do so“. Harry like most of the members was not eighteen so his father Henry is also named on the summons.  In the event, Eric Burgess successfully argued that they were not manufacturing explosives but conducting rocket propulsion experiments.  No one was found guilty. They agreed not to use Clayton Vale but another site in Glossop instead.

Pioneer 10 Plaque - the original idea from Eric Burgess

After the war Eric Burgess emigrated to America and worked for NASA and the space industry. He wrote many books including one of the earliest dedicated to rocket propulsion.

Perhaps Burgess’s most remarkable achievement is the least well known. Over dinner in November 1971 with Carl Sagan Burgess proposed that a message from humanity should accompany the Pioneer 10 destined for Jupiter in the following spring. Pioneer 10 would be the first man-made object to achieve solar system escape velocity and head in to interstellar space.  The plaque was designed by Carl Sagan and Frank Drake and successfully incorporated in to the mission in a very short time.  Although Burgess was informed about the plaque prior to launch, the image of a naked man and woman was so controversial in the 1970’s conservative America that NASA insisted on a news embargo until after launch.

Philip Turner

A plaque on display at the Smithsonian Institute in America recognises Eric Burgess’s contribution to space travel. In Manchester there is nothing to mark the unique achievements of Eric Burgess, Harry Turner, Malcolm Wade and others who were Manchester’s very first rocket scientists.

In this interview Philip Turner’s son, Philip talks about Harry but fist, Harry’s widow Marion on how she first met Harry.

BIS Northern Meeting York 19th May 2012

By 2 Comments

A British Interplanetary Society  meeting with a difference. The venue is in the North of England – the historic city of York. You don’t have to be a BIS member – all with an interest in spaceflight are welcome. A day long event with five speakers on subjects that include Lunar dust, Soviet & German spaceflight, origins of the BIS and technical details behind the phenomenal success of the Apollo progam.

A summary below. Full details in the pdf indicated at the bottom of the page.

* * *

Date: Saturday 19th May 2011
Venue: Denham Room : Priory Street Centre, York , Y01 6ET
Cost: £5.00 – Full day event – Seating capacity limited to 50
Tickets – Book online here

Confirmed speakers

Deadly Lunar dust (Dr John Cain  – UK Space Biomedicine Association). The first extraterrestrial material transported by man from an alien world to Earth was the almost 400kg of lunar rocks and dust. It is mysterious, fascinating but dangerous too. What were the hazards to the Apollo astronauts who brought it here and what has been learned by the scientist in the 40 years of laboratory experiments?

Origins of the BIS in the Northwest (Gurbir Singh – https://astrotalkuk.org). The BIS was founded in the northwest of England in 1933. The key players were Philip Cleater in Liverpool and from 1936 until the end of the war, Eric Burgess in Manchester. How did they realise their ambitious vision of establishing an Interplanetary Society a quarter century before a satellite was actually put into orbit?

How Apollo flew to the Moon (David Woods – How Apollo flew to the Moon). The Apollo program that took two dozen men to the Moon between 1968 and 1972 succeeded because of ingenious technological solutions developed rapidly midst the haste of the cold war. The author of the book, “How Apollo flew to the Moon ” explains the details of one of mankind’s most remarkable technological achievements.

China’s Long March to the Cosmos  (Mike Hall – www. aelitauk.com) China was the third country to independently launch humans in to space. That was almost a decade ago. Further success has been swift, including a space walk and a woman in space. Current active programs include lunar orbiter, lunar lander, mission to Mars and a Space station. As we approach the 40th anniversary of the last men on the Moon, why is it that most experts believe that the next one will be Chinese?

German Rocket Development (Martin Dawson – York Astronomical Society). ‘Modern rocketry and spaceflight owe a lot to German rocket development of the 1920’s, ’30’s and ’40’s. Although born as a military weapon, scientists and engineers have turned this sword into a plough share. German rocketry is a story that should not be forgotten, it has highs and it has lows, but is always fascinating.
