The Farthest

With all the horrors and depressing events going on currently in the world, it is refreshing to be reminded of a human endeavour that was wholly positive in outlook and execution. The Farthest is the story of the two Voyager space crafts which were launched way back in 1977. These probes were tasked with two objectives - to explore the outer planets and to carry messages to other potential life forms deep into interstellar space. At one point in the late 70's it became possible for this mission to be achievable, a time which occurs approximately once every 175 years where Jupiter, Saturn, Uranus and Neptune are aligned in such a way as to allow a space craft to travel between them using the gravity of one to propel it onto the next. This window of opportunity was grabbed and NASA formulated the Voyager programme, with Voyager 1 navigating the first two giant planets and Voyager 2 following behind but adding the final two to its trajectory.

Its genuinely quite an incredible story. Especially when you remind yourself that this extremely complex, technical and frankly unprecedented undertaking was achieved using mid 70's technology. In 2012 Voyager 1 became the first man-made object to leave our solar system and reach interstellar space, having orbited all four of the giant planets taking a series of incredible pictures of them and their moons. It achieved this with computer memory a tiny fraction of what can be found in a modern smart phone. Its bordering on a miracle that this mission was accomplished, especially when you learn that certain moments were executed with split-second accuracy, a fracture of a second more would have led to destruction, such as the moment where the probe was propelled between the atmosphere of Uranus and one of its moons. It's all the more impressive when you discover that the probes were re-programmable via communication with a craft which was over a billion miles away. It was in summary one of the greatest undertakings humans have ever executed.

The documentary takes a fairly traditional talking heads format where we hear recollections of various scientists involved in the programme. Its these moments themselves which add a considerable amount of emotional weight to proceedings, making it clear that these space probes were ultimately far more than scientific equipment, they represented something far more and quite wonderful. It's not just the scientific angle of the mission but also the philosophical, such as the moment late in the mission that the cameras were reversed to look back at Earth which was now a pixel, making it clear how small we are in the universe while simultaneously making us realise that we need to look after our small planet as this little dot on a picture is all we have. There is some considerable detail given to the golden record, which contains the music, sounds and imagery of Earth. The music ranged from Mozart to Chuck Berry (with The Beatles foolishly refusing one of their songs), the imagery constitutes about one hundred pictures which attempted to convey the world as much as possible. This alien contact element of the mission was unsurprisingly given a lot of publicity at the time but it is only now that the probe has finally left our solar system that this has become the whole mission. But really, the imagery of the four mysterious giant planets is the real pinnacle of the Voyager missions and the incredible imagery that it captured remains quite extraordinary. These probes will more than likely hurtle onwards through deep space at 10 miles per second for billions of years long after our planet and sun are gone, and that says it all really.

In 1977, NASA launched Voyager1 and Voyager2. They traveled to the lesser-known outer planets and some of the moons orbiting them. The planets' rare alignment made it an opportune time. Carl Sagan is the driving force behind the golden record of earthly sounds which became the media focus.

This is slightly better than most PBS hour long specials. It's actually 96 minutes and packs an emotional punch. The wide-eyed poetry of exploration is well presented. This is a lot things. It's an underdog story. It's a scientific documentary. It's an exploration thriller. It brings back all the great discoveries. This could be great for inspiring a high school science class.

Mankind left its fingerprint in the outer space wit Voyager 1 & 2. This is, by far, the most remarkable thing human beings ever accomplished. And I could never be more proud and honored. Thinking that a man-made object will last billions of years, longer than we'll ever be able to exist, probably, it just blows my mind. At least this would be a signal for aliens to know that, far away, on a pale blue dot, a species of creatures called humans reached their goal of sending the message that we were here and we would never be forgotten. Documentaries like these prove that the sky is not the limit and that men are capable of doing things that are far beyond their potential. What we have done is more than history, it is a story worth sharing with... aliens.

The Voyager mission is one of the most interesting in of all NASA. Two spacecraft which have been functioning since their launch in 1977, the year I was born, are still sending data as they race outside of the Solar System. This film is telling the story of the mission and the people that worked in it and how important this mission was for the knowledge and identity of our species. The quote that stuck in my mind was "We've gotten away with it!", said by one scientist as he described his enthusiasm of the launch. I mean, here are these super smart people, planning ahead for decades one of the first and few real spacecrafts we humans have ever built, and what they feel is that they slipped it under the nose of their government and nation and species. I loved every one of the scientists that contributed to the show, their youthful enthusiasm so contrasting with their advanced ages, revealing the light in their hearts.

The film was a bit too long, at two hours, and maybe it would have been more powerful as a mini-series instead. It goes through the excitement when it first reaches Jupiter, then Saturn, then the bitter sweet moment when Voyager 2 reaches Uranus at the same time that Challenger explodes and finally Neptune. Another quote was about how small color dots from the Earth telescopes turn into worlds when Voyager goes past the planets.

I love all of these documentaries, which show who worked passionately to make things like these happen, to truly further humanity against all odds and against its mostly indifferent members, shows that really show the worlds around us and expand our horizons. If you love space, you should see this.

I'm a scientist and used to love astronomy. After watching this film it made me feel that the whole human race owes a debt of gratitude to the architects of Voyager 1 & 2, surely the most important space missions to date. It was pitched at a perfect level, being understandable, thoroughly informative and gripping. Documentaries can be dull at times, but this had me listening to every single word and feeling a rush of almost spiritual elation at what we achieved as a human race. My thanks go to the film makers for such a wonderous and inspiring film, depicting how humans can reach beyond our small world both metaphorically and literally.
