SpaceX expanded its constellation of low-orbit satellites on Saturday by launching 53 Starlink satellites from Florida.
The Falcon 9 rocket launcher launched from the launch site at Cape Canaveral at 7:19 a.m. Eastern time and took out satellites about 16 minutes after launch.
The first stage of a reusable rocket, which was used for multiple launches, including the first flight of SpaceX's spaceship Crew Dragon, successfully returned and landed on the unmanned ship "Just Read the Instructions" in the Atlantic Ocean.
It will be recalled that SpaceX launched four astronauts at the International Space Station earlier this week, including the 600th person who had been in space in the last 60 years.
A spaceship launched from the Kennedy Space Center of NASA reached a shining space outpost in 21 hours.
When the astronauts first saw the space station from a distance of 32 km, they were very emotional and called it a "great sight."
Instead of the usual seven astronauts, the crew welcomed three.
This happened because SpaceX returned four of them on Monday, after the launch of their replacements was delayed all the time.
The new crew will be on the space station for the next six months, during which time two groups of tourists will be admitted.
