SpaceX completes launch and landing double bill
At the end of Friday, it used one of the new Falcon 9 vehicles to set up a satellite of the Bulgarian Florida.
Then, on Sunday, SpaceX has brought another 10 spacecraft to Iridium telecommunications company. This time, the rocket flew to California.
Both missions have seen the earliest stages of the Falcon return to Earth under the control of unmanned drones that had settled in the ocean.
This means that SpaceX has now had the successful landing of 13 missions that it has tried to recover. That said, the first leg of Friday had a particularly difficult landing, and relied on the live video sequence.
“Rocket is extra toasted and hit the hard cover (used almost every emergency kernel for emergencies), but otherwise okay,” plaisanché SpaceX CEO Elon Musk on Twitter.
Your company does not expect to recover each actuator, as the flight profile required in many satellite launches will trigger re-entry speeds fast enough to reduce available propellant.
Friday’s mission was launched from the east coast of the United States, the famous Apollo and transfer from the Kennedy Space Center, 39A.
The “Falcon 9” second-hand was lifted at 15:10 local time (19:10 GMT).
His companion, BulgariaSat-1, was dropped into orbit about 30 minutes later.
The spacecraft is used to broadcast television in homes in Bulgaria and Serbia.
The Falcon amplifier was last flown in January to launch 10 satellites for the Iridium mobile phone and retransmission data. And it was another launch of Iridium that completed the weekend activities.
This second mission in a new Falcon, occurred on the west coast, from the air base of Vandenberg.
Iridium is slowly replacing its global satellite network. Another 10 has increased in this last flight.
SpaceX still has six launches in Iridium’s books, the network of more than 60 existing spacecraft is now well beyond its design life.
The takeoff took place on Sunday at 13:25 local time (20:25 GMT). The return amplifier on this occasion was new titanium flap to help steer the vehicle towards its unmanned waiting craft.
Titanium is more robust than the previous type of aluminum, Musk said, eliminating the requirement for repair or replacement. This should speed up the recovery of future engines for reuse.
“The new titanium grille flap worked even better than expected. It should be capable of an indefinite number of flights without service,” said the CEO.
The new Iridium replace a network of more than 20 years
The cases are Iridium mobile communications, with connections to anyone not near a landline. These clients include military, oil and gas platforms, ships and broadcasters.
Increasingly, which also includes the remote machine reports its status to a central server. This service machine manufacturer has a great future, especially as more and more devices are connected to each other in the future “Internet of Things”.
The new headquarters of Iridium also payloads from two tracking companies. One of them is Aireon, whose objective is to offer a service that informs the positions of the aircraft by detecting its transmissions ADS-B (automatic dependent surveillance). This would be useful for tracking aircraft out of radar coverage, but could also help airlines plan more efficient route.
The other payload housed for EaxtEarth, which is something very similar to ships. Large ships transmit an automatic identification system message that can be detected from the orbit.
