According to foreign media, there was a problem with the valve assembly of the second stage of the Falcon 9 rocket,Space X, the US space exploration technology company, has delayed the launch of the next batch of Starlink satellites. The next attempt will take place on February 17 local time (Beijing time 18), the company said.

Figure: in May 2019, the space X Falcon 9 rocket will supply the crs-17 cargo dragon spacecraft for NASA. The same booster is planned to launch the satellite chain tomorrow

Space X was originally scheduled for 10:25 a.m. Eastern time on February 16, when it launched 60 star chain satellites with a four handed Falcon 9 rocket at launch pad 40 at Cape Canaveral Air Force Station, Florida. However, the rocket's hardware problems caused the company to delay the launch for 24 hours.

A representative of space X wrote on Twitter: "the launch of the satellite chain has been suspended and the team is carefully examining the components of the rocket's second stage valve. The goal now is to launch on February 17 local time. "

This is not the first time that the launch of the satellite chain has been delayed, after bad weather conditions prompted space X to postpone the launch to the weekend. Space X completed the mission's pre launch test on February 14. The company had hoped to launch the rocket on February 15, but after studying the weather forecast, it found that the 16th was a more suitable date.

The two-stage Falcon 9 rocket, which launched the satellite chain, had flown three times before, sending the cargo dragon spacecraft to the international space station in May and July 2019 respectively, and a heavy communication satellite into orbit in December 2019.

After the successful launch, the rocket's first stage is expected to land on SpaceX's unmanned recycling boat, marking the company's 50th successful recovery of the booster. SpaceX is also trying to recover the payload fairing and has deployed its two recycling vessels. Elon Musk, SpaceX's chief executive, said the moves would ultimately reduce launch costs.
