Us company SpaceX in one weekend held two successful launch of their rockets, the Falcon 9. The SpaceX launch was 9 this year. Currently, the company has surpassed the record for most launches in one year, which he established in 2016. The last mission: deliver a group of satellites into orbit for a company called Iridium. These satellites will join the growing network, dubbed Iridium Next system. At Iridium, there are a lot of goals. One of the most notable is the elimination of "black zones" where the commercial planes cannot be tracked, providing global monitoring of all flights in real-time. This means that the missing aircraft such as the Malaysia flight that disappeared 3 years ago in the Indian ocean, unable to leave in the past. To orbit will require several launches. The start Sunday was the second SpaceX supply - in January, he sent the first 10 satellites. Next year will be another 6 missions Iridium. SpaceX wants to reuse its rockets to dramatically reduce the amount for one start.
