SEA: Space Exploration & Astronomy

Of all the spacecraft to have visited other worlds, there are two which have travelled further than any other, discovering more about the Solar System than their inventors ever could have imagined. They are the legendary pair of Voyager Probes- still the only spacecraft ever to have visited the Ice Giant planets, Uranus and Neptune. The story of their 40 years in space makes up the topic of our video today- from the gas giants, to the ice worlds, and then out into the depths of interstellar space...

Far beyond the reaches of the four rocky planets, we find our Solar System's showpiece worlds- the two gas giants, Jupiter and Saturn. As the two largest planets, they both make tantalising targets for probes exploring the planetary neighbourhood, but both lie significantly further from the sun than the Earth and its terrestrial neighbours. But early in the 1970s, the technology for deep space voyages was primed, and missions to both Jupiter and Saturn ensued. Those missions make up the topic of our video today, in this second episode of our trilogy of Probes that Studied the Solar System.

From studying the dusty surface of Mars, to plunging into the atmosphere of Venus, over the last 60 years, we've launched hundreds of probes into space on trajectories to visit each of the terrestrial planets. But for all the fascinating discoveries made on the way, humanity's journey towards the stars started out in a much darker place- a battlefront between the world's then two great competing superpowers. And in this first episode on my new series on probes, we will revisit this space race, and the major milestones on route to visiting each of the terrestrial planets.

Earth is a success story, a thriving world that has hosted life for almost 4 billion years. But, no matter how peaceful things are now, a new age is coming for the Solar System. An age of change, destruction and evolution. A place for new worlds and new stories, but one in which the Earth has no place.

The Solar System is vast and diverse, home to eight large planets, including one which gave rise to life. While humanity was born too late to witness the events that occurred at the birth of the Solar System first-hand, by peering into the surroundings of others stars, we are starting to piece together the events that unfolded at the birth of our own Solar System. Today, we shall explore the culmination of these decades of research, as we tell the story of the birth of the Solar System.
