Threat Storm Scramble SpaceX Launch – Spaceflight Now



SpaceX's "Falkon 9" missile is at the launch site of Cape Canaveral Complex 40 during the Wednesday countdown. SpaceX

SpaceX called Falcon 9's countdown on Wednesday because of the thunderstorm lightning strike on the Florida coastline, backing the departure of the International Space Station's cargo mission to Thursday. is not expected to be much better on Thursday afternoon when SpaceX has another flashing start window at 6:01:56 EDT (2201: 56 GMT) to send a Dragon ship to the space station

Widespread thunderstorms, moving southwest-northeast through central Florida, brought rain and thunder to Cape Canaveral. Despite the bleak forecast, SpaceX continued with the loading of kerosene and liquid oxygen propellants in the Falcon 9 two-speed rocket, with the countdown counting to scheduled take-off at 6:24:30. EDT (2224: 30 GMT)

Two rules for the launch time for surface anvils and anvil clouds have remained "do not go out" for launch as the countdown was zero. SpaceX interrupted the countdown at T-minus 30 seconds, and teams began procedures to drain Falcon 9 from its liquid rocket fuel and set up for a new trial on Thursday.

Hold, hold hold for Countdown 1, a member of the SpaceX Launch Command came out on the T-minus countdown network for 30 seconds.

"An interrupt script is running," another engineer said.

SpaceX hopes to be more lucky on Thursday to begin the company's 18th mission to supply the International Space Station under a multi-billion-dollar contract with NASA

"Please continue with … clean up post-static procedures. . The Dragon Capsule loaded with 5097 pounds (2,312 kg) supplies, equipment and experiments for the crew of the six people. Canaveral expects such conditions on Thursday when the cosmodrome was tested on Wednesday afternoon. An updated forecast, released Wednesday night, predicts a 70 percent chance of weather preventing Thursday's release. For the lightning strike, the Air Force team tracks lightning strikes to ensure that no recent ejections have occurred within a radius of 10 miles from the launch site or within 10 miles of Falcon 9.

The cloud rules from the anvil refer to the problems with missile-activated lightning.

"These are a little more scary for us because it may seem that the weather is clear, maybe there has been no lightning in the last 30 to 45 minutes. , but if you send a rocket through this cloud cloud, that cloud can still be charged enough to cause additional lightning strikes, "said Will Ulrich, the 45th-hour officer at a press conference Wednesday morning

NASA and SpaceX may have to wait up to a week for the next chance to send the Dragon Freight Ship to the International Space Station.

The space station position in its orbit prevents the launch of the Dragon spacecraft in op days, and a Russian ship Progress must leave the orbital complex on July 29, laying the foundation for docking a fresh ship. Progress supplies a ship on July 31st.

Normally, it takes two or three days for a Dragon freighter to reach the space station after its launch from Cape Canaveral. If the mission is able to explode today, the SpaceX forwarder will arrive at the space station on Friday.

NASA and SpaceX are looking for another opportunity to launch on the backdrop of lively bandwidth. Otherwise, the next attempt to put it into operation after Thursday may be later than August 1, officials said.

The procurement mission was planned before July 21, but SpaceX delayed the flight three days after repairing the liquid oxygen leak in the first stage of Falcon 9 last week set up marketing preparations behind schedule. carrying the astronauts to and from the station. NASA has paid for the third international dock adapter to replace the first IDA block lost in failure to release SpaceX in June 2015.

SpaceX successfully delivered the second IDA to the station in July 2016 earlier this year on an unmanned test flight that is associated with the orbital research post.
