SpaceX Launches Rapid Reuse Falcon 9 Rocket

The Grace-FO satellites deployed roughly 11 minutes after launch, while the Iridium satellites are due to be released roughly an hour after the launch.
While SpaceX has previously recovered and reused the Falcon 9 rocket's first stage, the company won't be recycling that piece of equipment from this launch.
NASA's Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) is a follow up to the original GRACE mission, which launched on 17 March, 2002 and lasted far longer than the projected five year lifespan. Viewers will be able to watch the lift off and separation of the satellites, but SpaceX will not be recovering this older booster as it shifts its focus to the final version of its workhorse rocket.
GRACE satellites (including these two new satellites) fly in uniform pairs so that scientists can have a better read on how much mass is below the flight path.
SpaceX, the rocket company founded by Elon Musk, will use its Falcon 9 rocket to launch seven satellites on Tuesday: two state-of-the-art NASA satellites and five commercial communications satellites. The launch will pose a special challenge for SpaceX as it requires the two payloads to be delivered at different altitudes, with NASA's hardware being deployed at around 300 miles and the Iridium NEXT satellites at almost 500 miles.
SpaceX's recovery ship, Mr Steven is heading out into the ocean to attempt to catch at least one half of the expensive shell used to protect spacecraft during the early phases of launch.
The McLean, Virginia, company now has 55 Iridium NEXT satellites in orbit. The satellite can do this by keeping track of the changes in Earth's gravity field, which is caused by the movement of water, ice, land and the inner solid parts of the planet. This launch makes the Iridium NEXT satellite constellation a conglomeration of 75 satellites (nine of which are spares). The GRACE-FO satellites will trail each other in ideal synchronization for roughly 137 miles (220 kilometers). It is a successor to the original GRACE mission, also a U.S.
The GRACE-FO satellites were assembled by Airbus Defence and Space in Germany.
The first-ever SpaceX launch from Vandenberg AFB Space Launch Complex-4 occurred on Sunday, Sept. 29, 2013.
"GRACE was really a revolutionary mission for us understanding the water cycle and how the climate behaves and the trends that are taking place", said Frank Webb, GRACE-FO project scientist at NASA's Jet Propulsion Laboratory.
Once the Earth-facing satellite has put a safe distance between itself and its sibling, it will thrust back up into a higher orbit, so that one follows the other on the same trajectory.
