This is the sixth batch of satellites of the global Internet access system.
SpaceX company launched the Falcon 9 launch vehicle, the launch of which on March 15 was automatically delayed a few seconds before the start due to the fact that during the engine check the control data went beyond the standard limits.
15 minutes after launch, the rocket launched into orbit about 290 km in height 60 satellites of the Starlink global Internet access system, each of which weighs about 260 kg. After checking the operability, the satellites will independently rise to a working orbit of 550 km within several months using ion engines.
Note that the first stage used in this mission has flown four times already: twice – in 2018 and two times – in 2019. But this time it was not possible to put her on an unmanned ship. In November last year, with its help, the second batch of Starlink satellites was launched into orbit. The current party is the sixth. Three of the six launches were completed this year: the fourth in late January, the fifth in February. In total, SpaceX plans to launch 1,500 Starlink satellites in orbit over the course of the year.
