SpaceX postpones Starlink satellite launch again, for 'about a week'

In a tweet, SpaceX offered this explanation: "Standing down to update satellite software and triple-check everything again".

"Always want to do everything we can on the ground to maximise mission success, next launch opportunity in about a week".

So we'll do this again in about a week. The company will livestream the launch here.

On Thursday, the rocket stands again at the launchpad.

Noting it is a "multibillion dollar endeavour", he said that SpaceX has enough capital for the time being. While 60 satellites in a single launch is an incredible feat, SpaceX will need thousands of the Starlink devices in order to ensure the new communications network works as intended, and that means many more launches in the future. Including that tidbit in the delay announcement suggests that the company is aiming to have its satellites updated and ready by that time.

He said that the mission will be the heaviest payload SpaceX has ever launched at 18.5 tons.

At the same time, I didn't know what I believed. "Should I be locked away?" In the days since, things really changed for Gunn. Gunn has been quiet about his return, and his exit, ever since the original firing - but he's finally spoken out.

SpaceX hoped to have 60 custom communication satellites in orbit today, but instead, it has zero.

Starlink is different. SpaceX says putting a "constellation" of satellites in low earth orbit would provide high-speed, cable-like internet all over the world. "This is very hard", Musk said.

Musk said in a call with reporters Wednesday that the satellites will begin deploying about one hour after launch. "There's a small possibility that all of these satellites will not work". Richardson joined our team shortly thereafter.His passion for space ignited when he watched Space Shuttle Discovery launch into space October 29, 1998.

Following stage separation, the main stage booster engine will attempt landing on drone ship "Of Course, I Still Love You" in the Atlantic Ocean. "They don't know", Kremer added. Once released, the satellites will use solar panels to power themselves. Musk said he is concerned about the solar panel deployment, and he noted that there are two different deployment mechanisms on the satellites for this goal. For example, each will maneuver with Hall-effect thrusters (these are ion thrusters in which propellant is accelerated by an electric field). Frustrated with the pace at which Starlink satellites were being developed, he fired at least seven members of the program's senior management team at a campus in Redmond, Washington, outside Seattle, Reuters reported. The list price for a Falcon 9 launch is $62 million. The goal is to get low-latency internet access to large swaths of the globe. In February, Airbus SE-backed OneWeb launched its own clutch of satellites, while LeoSat Enterprises and Canada's Telesat are also working to build data networks. But SpaceX appears to be well ahead of most of the rest of the field. The company will need 12 launches for moderate coverage, according to Musk. A dozen launches would bring "significant" connectivity, he said, and 24 launches would bring near-worldwide service. So although 12,000 satellites sounds like a lot, it's only a fraction of the infrastructure that SpaceX will have to construct.

It is expected to take more than five years and $9.8 billion (£7.1bn) of investment, although satellite internet has proved an expensive market in the past and analysts expect the final bill will be higher.
