To that end, SpaceX launched and landed a reused Falcon 9 for the first time back in March, and it also recovered that rocket's fairing a first for the company.
A second batch of new satellites for Iridium Communications was sent on board the SpaceX Falcon 9 rocket.
SpaceX, an Elon Musk company, will be launching their latest Falcon 9 rocket some time today.
This is the second set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium's next generation global satellite constellation, Iridium NEXT. The first stage of the rocket was previously used during a January mission.
The last time USA rockets launched such simultaneous types of rockets in two days apart was in 1995 when both Lockheed Martin Atlas and Atlas-E sent two separate missions into space with the intention of delivering Intelsat broadcast and Air Force weather satellites to space. The only exception was June 2016's launch of the Eutelsat 117 West B and ABS-2A satellites, where one of the three engines used for the landing burn did not generate sufficient thrust.
The primary mission was also a success, with SpaceX deploying the BulgariaSat-1 satellite into geostationary transfer orbit as of around 3:45 PM EDT.
Friday's launch was the second time SpaceX has launched and landed a reused first-stage. The satellite was designed and built by Space Systems Loral, or SSL.
This launch is expected to mark the beginning of a busy weekend for Musk and company. "Launch at 1:25 delivering 10 satellites for Iridium". "Good chance rocket booster doesn't make it back", Musk said. Its payload, BulgariaSat-1, was later placed into its desired orbit. The first stage booster landed itself upright on a drone ship called "Just Read the Instructions" during high winds only eight minutes after launch.
Rocket is extra toasty and hit the deck hard (used nearly all of the emergency crush core), but otherwise good.
