Future Space
Voyager 1 and 2 carry coded messages to potential alien civilizations, but are we sure we are ready to be discovered by aliens? The Voyager spacecrafts were built to fly past the outer planets and study them closely, the first time in human history they’d been observed up close. The spacecraft was a great success, greatly expanding the field of planetary science. They didn’t go on to become the most intrepid explorers on Earth until they had completed their main goal.
