SpaceX founder Elon Musk once said that he would measure the success of his company's efforts to land and reuse rocket boosters when it became so routine that it was no longer newsworthy.
Now, since December 2015, the company has landed a total of 16 rockets, on either a landing platform at sea or its helicopter-like landing pad at Cape Canaveral Air Force Station in Florida, turning what was once a jaw-dropping and unprecedented bit of aerial artistry into a somewhat ho-hum, to-be-expected exercise. SpaceX has landed so many rockets that it can be easy to forget just how difficult - and majestic - the feat actually is.
Perhaps that's why Musk on Thursday morning presented a blooper reel of the company's many failed attempts, a two-minute video, set to a John Philip Sousa march, of explosion after fiery explosion.
There are rockets crashing into a landing platform at sea and into the ocean itself, and one test vehicle that went awry and exploded in midair. Each one is a reminder of how difficult, and revolutionary, the achievement actually is.
Since its founding in 2002, SpaceX's goal has been to significantly lower the cost of space travel, making destinations such as Mars achievable.
