An appointment to the United States Military Academy at West Point, New York was the next definitive port of call after a successful Civil Service competitive examination. Graduating from the Academy in 1955 with a Bachelor of Military Science degree, Worden’s career from then on went down a route now accepted as the norm for an Apollo-era astronaut. “It was only in the early 60s that I realised we actually had a space program and that it might be something worth looking into.”Having chosen the Air Force after graduation from West Point, Worden went on to receive flight training at various bases in Texas and Florida. A Master’s degree in Astronautical/Aeronautical Engineering with Instrumentation Engineering at the University of Michigan in 1963 preceded stints as a test pilot at the Empire Test Pilot’s School (then situated in Farnborough, England) and then as an instructor at the Aerospace Research Pilot’s School at Edwards Air Force Base in California. Worden remembers his time flying in England particularly fondly, having decided to live with his family in a bungalow five miles south of Aldershot as opposed to staying holed up in an American base.Selected as one of nineteen members of NASA’s fifth group of pioneering astronauts in 1966, Worden was eventually assigned as the backup Command Module Pilot (CMP) on Apollo 12. The prime CMP that eventually flew on that mission was Dick Gordon, and the constant training together meant a lifelong friendship was formed. “Dick was my buddy. We flew together and worked together for a year and a half when he was training for Apollo 12 and I was his backup. We just went everywhere together. We worked really hard but it was also a lot of fun.”Worden was selected, along with fellow distinguished Air Force pilots Dave Scott (Commander) and Jim Irwin (Lunar Module Pilot) to form the crew of Apollo 15, the fourth manned lunar landing, launched on July 26th, 1971. When asked if he would have traded his mission for any others, Worden maintains “Well, maybe Apollo 11, that would’ve been nice. But no, I think we had the best mission of them all. We did the most science and concentrated on that.” He points out that “there were a lot of firsts on our flight that made it a really great flight to be on.” He’s right – Apollo 15 was the first of three ‘J’ missions which concentrated more on science than any previous flights. The mission included the first Scientific Instrument Module (SIM) bay flown and operated on an Apollo flight, the longest lunar surface stay time (Scott and Irwin’s lunar module Falcon remained on the surface for almost 67 hours), the first use of the lunar roving vehicle (or ‘Rover’) to travel further on the Moon’s surface than ever before, as well as the first sub satellite launched in lunar orbit.On the return trip to Earth, Worden himself completed an historic first spacewalk (Extra-Vehicular Activity or EVA) in deep space. During his 38 minutes outside Endeavour, he retrieved film cassettes from the SIM bay and observed the general condition of equipment situated there. As the first person to view the Earth and the Moon from deep space outside a spacecraft, it was a personal mission highlight for Worden. “I’d watched the Earthrise 75 times before that so that was an old thing by then, but to see the Earth and the Moon at the same time like that was kind of unique.”Training for that spacewalk was a key element of Worden’s mission preparation, with underwater training and parabolic zero-g flights in the aptly named ‘Vomit Comet’ KC-135 aircraft. Colonel Worden asserts however that the water training wasn’t much of a help. “The underwater training was useless. The problem is you have to get into your spacesuit and then get into the water and get neutrally buoyant. Everything you work with in the water has to be neutrally buoyant and that’s a far different thing than working with the same mass in space.” He does note however that “The water tank is OK for procedures, but to get a real view of what it is like in space it’s not the right thing. The zero-g airplane is the way to go.”One key aspect of training for Apollo 15 was geology, and it is said that all of the ‘J’ mission astronauts (Apollo 15, 16 and 17) had the equivalent of a Master’s degree in geology by the time they each flew. While Scott and Irwin were taught field geology, Worden became completely immersed in learning how to be an aerial lunar geologist. His teacher was Farouk El-Baz, an Egyptian-American scientist who would take Worden on flights above places of geologic interest so he could practice describing what he saw. El-Baz is still a big name in his homeland Worden points out. “Farouk was trained as a petroleum geologist. But what he has really done is remote-sensing geology and his big thing right now is ground-penetrating radar. He has found several Egyptian tombs and artefacts and they’ve been excavating those things. He’s kind of a hero over there.”The flights to the moon between 1968 and 1972 affected each of the astronauts in very different ways. When asked if the Apollo 15 mission changed him at all Worden contends “Only from the standpoint of what I could see when I was there that I couldn’t see here.” He adds that “…you see how many stars there are out there and you realise that the Earth is a finite object. Five billion years from now there won’t be an Earth – it may occur sooner than that, who knows?”Worden seems convinced that it is only a matter of time before humans take the next giant leap in manned space exploration. “My opinion is that we are genetically driven to go into space. We might take a thirty year slow walk, a hiatus or whatever you want to call it, but we’re eventually going to get back to it and we’re eventually going to go on and do these things that we’re talking about.”Many of the Apollo astronauts seem somewhat divided on the matter of whether we should go back to the Moon before sending people on to Mars. Worden is certain however that a return to the Moon is a waste of time. “There’s one thing that it would be very nice to go back to the Moon for. If we could put a big observatory on the surface of the backside of the Moon, that would be absolutely unbelievable. Other than that the Moon is no good to us for anything.” Even in terms of a launch platform to Mars, the Florida resident believes the International Space Station (ISS) would be a much wiser option than the lunar surface.On September 16th NASA announced that it had chosen Boeing and SpaceX as the two commercial companies that will fly astronauts to the International Space Station from 2017 onwards. The $4.2bn awarded to Boeing and $2.6bn to SpaceX will lessen the American reliance on the Russian Soyuz vehicles to get its astronauts into orbit, and is also seen as a key step towards replacing the Space Shuttle fleet, which retired in 2011 after over 30 years of service. Worden feels that for any manned space venture to work “You’ve got to have a vision and you’ve got to have a focus if you’re going to bring people together and do things efficiently.”Boeing’s CST-100 and SpaceX’s Dragon capsules are both set to be reusable vehicles which will carry at least four crewmembers and limited cargo to the ISS, as well as act as an emergency lifeboat by remaining docked to the station for up to 180 days. SpaceX’s CEO Elon Musk sees the announcement as “a vital step in a journey that will ultimately take us to the stars and make humanity a multi-planet species.” Worden thinks space travel is being privatised because commercial companies will do it “more efficiently” than government. When asked whether the move is a long-term solution or just a mere stopgap measure he contends “I think it’s a long-term thing. Commercial flights into low-Earth orbit or to the ISS is a good thing because it takes the pressure off NASA to do that.”In terms of whether we’ll ever find any other living species in the universe, Worden seems convinced. “If you talk about whether there is intelligent life out there, the answer is absolutely, resoundingly yes. It’s deductive reasoning really.” With 300 billion stars in our Milky Way Galaxy alone, it is hard to argue with him.Worden’s autobiography, Falling to Earth, was released in 2011 and made it to the top 12 of the LA Times Bestseller list. Written with Manchester-born space historian, author and current Director of Education at the San Diego Air and Space Museum, Francis French, the book is a fascinating insight into the thoughts and experiences of an Apollo astronaut.Worden’s recent visit to the Irish west coast was organised by Limerick native Paul Ryan. A hugely successful few days included a lecture at Limerick IT on September 16th, before concluding with a dinner event at the Pavilion in the University of Limerick the following day.The 82-year-old has no intention of slowing down his schedule just yet. “I enjoy doing this, I enjoy talking to people. It keeps my feet on the ground.” Having flown a half-million mile round trip to the Moon over 43 years ago, terra firma must feel that bit more precious. Al Worden – the boy from Michigan who took a trip to the Moon.The above interview was exclusively conducted at the dinner with Al Worden event held at the Pavilion on the University of Limerick campus on September 17th, 2014.
