[Updated 20190517_020607 UTC. According to SpaceX's twitter feed:

Standing down to update satellite software and triple-check everything again. Always want to do everything we can on the ground to maximize mission success, next launch opportunity in about a week.

Original story follows.

From the live stream on YouTube:

SpaceX is targeting Thursday, May 16 for the launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. SpaceX’s Starlink is a next-generation satellite network capable of connecting the globe, especially reaching those who are not yet connected, with reliable and affordable broadband internet services.

The launch window opens at 10:30 p.m. EDT, or 2:30 UTC on May 17, and closes at 12:00 a.m. on May 17, or 4:00 UTC. Falcon 9’s first stage for this mission previously supported the Telstar 18 VANTAGE mission in September 2018 and the Iridium-8 mission in January 2019. Following stage separation, SpaceX will attempt to land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean. Approximately one hour and two minutes after liftoff, the Starlink satellites will begin deployment at an altitude of 440km. They will then use onboard propulsion to reach an operational altitude of 550km.

The live stream historically "goes live" approximately 15 minutes before launch which should be 1 hour from the time this story goes live.

Yesterday's launch attempt was cancelled due to unacceptable high-altitude winds. Courtesy of the National Weather Service, here is the current forecast and the hourly forecast for Cape Canaveral.

Yesterday (May 13th), we posted a story SpaceX to Launch 60 Starlink Satellites at Once, and More. Here are a few more details about Starlink and — more importantly — the launch schedule and a link to the YouTube page to follow along.

SpaceX plans to launch 60 satellites tonight for its next round of development and test towards its goal of deploying Starlink:

SpaceX has plans to deploy nearly 12,000 satellites in three orbital shells by the mid-2020s: initially placing approximately 1600 in a 550-kilometer (340 mi)-altitude shell, subsequently placing ~2800 Ku- and Ka-band spectrum sats at 1,150 km (710 mi) and ~7500 V-band sats at 340 km (210 mi). The total cost of the decade-long project to design, build and deploy such a network is estimated at nearly US$10 billion.

[Update (20190524_025416 UTC): Launch successful so far, booster landing successful, second stage is now in coast phase, satellite deployment coming up in about 40 minutes. Correction on YouTube link: https://www.youtube.com/watch?v=riBaVeDTEWI.]

On May 20th, SpaceX tweeted: "Now targeting May 23 for launch of Starlink from Pad 40 in Florida".

According to Spaceflightnow:

May 23/24 Falcon 9 • Starlink 1
Launch time: 0230-0400 GMT on 24th (10:30 p.m.-12:00 a.m. EDT on 23rd/24th)

Launch site: SLC-40, Cape Canaveral Air Force Station, Florida

A SpaceX Falcon 9 rocket will launch 60 satellites for SpaceX's Starlink broadband network. Scrubbed on May 15 and May 16.

The launch will be Live-Streamed on YouTube:

    According to their website [spacex.com], they are

    "... postponing our launch of 60 Starlink satellites to update satellite software and triple check everything again--always want to do everything we can on the ground to maximize mission success. The next launch opportunity is targeted for about a week (exact date TBD)."

      Also on Twitter [twitter.com]. Sure looks like the launch is scrubbed for now.

    How are they catching software bugs on satellites that are already sitting on the launch pad? That must be a compressed development schedule.
