SpaceX has made some excellent strides in recent months by proving that it can successfully launch, recover, refurbish, and re-launch its rocket technology. This has been a huge achievement, as reusable rockets have the potential to significantly alter the future of space travel by lowering the cost of launches, leading to greater access to the cosmos.
But SpaceX wasn't an overnight sensation. Their monumental accomplishment has been developing for years, subject to testing and retesting, with successes and failures all along the way. The Verge was kind enough to compile footage of each of the company's landing attempts, whether it was a success or went up in flames.
The first two launches were attempted in January and April of 2015, and both ended with unfortunate booms. But the company must have learned some valuable lessons since the third attempt in December of 2015 was a success. The next few landings were a mixture of successes and failures, but SpaceX has been succeeding for more than a year straight now.
SpaceX's journey is an excellent example of the perseverance needed to thrive in science and technology. These are fields of testing, retesting, confirming, and rethinking — not overnight successes.
