Discussion thread for Starlink v1.0 L21
NSF Threads for Starlink v1.0 L21: DiscussionSuccessful launch 14 March 2021 at 6:01am EDT/10:01 UTC on Falcon 9 (booster 1051-9) from LC-39A. ASDS landing on OCISLY was successful. Fairing recovery is expected.Payload: A batch of 60 Starlink satellites. Expected deployment orbit of approximately 260x280km.
The Falcon 9 first stage rocket booster supporting this mission previously supported launch of Crew Dragon’s first demonstration mission, RADARSAT Constellation Mission, SXM-7, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. Falcon 9’s fairing previously flew on the Transporter-1 mission.

Starlink Discussion Thread for all general discussion on Starlink.

Starlink Index Thread for links to more Starlink information.
L2 SpaceX:
https://forum.nasaspaceflight.com/index.php?board=60.0From a previous mission's Press Kit:
Each Starlink satellite weights approximately 260 kg and features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of Falcon 9’s launch capabilities. With four powerful phased array and two parabolic antennas on each satellite ... At end of their life cycle, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event their propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes. Further, Starlink components are designed for full demisability.
Starlink is targeting service to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

Cross-post:
Will this actually fly in February?.
Most likely around Feb 21 timeframe from SLC-40.
A NET of Feb 21 (min 8 days) but also a Likely NLT Feb 27 (14 days).
The limitation is booster availability mostly. 1051 would be a L2L of 32 days on the 21 Feb and 35 days on the 24 Feb. 1058 would be a L2L of 28 days on the 21 Feb and 35 days on the 28 Feb.
Note that it is possible for a L21 launch from 39A with a NET of Feb 25 to a NLT of [Mar] 3.
5 launches in Feb still a possibility!!!!!!

Due to delays of Starlink v1.0 L17 and limitations at LC-39A, this launch is unlikely to take place in February. Will most likely be first week of March.

There are 2 booster available for use for this flight: 1060.6 at 37 days L2L and 1051.9 at 52 days L2L.
Also even though the ambitious 9 day pad turnaround for 39A is possible in practice due to many obstacles it has been more like 11 to 14 days. Putting a more likely launch date as 15th to 18th.

There have been multiple threads on this topic [increasing launch frequency]. These are not new ideas, and have been thoroughly discussed.
I would suggest going through this thread to start:

This is definitely going to be delayed. JRTI is busy with L20 and OCISLY is still in port.

According to the TFR for March 14, what time would the launch be?, it seems that the window is a little earlier now.
https://tfr.faa.gov/save_pages/detail_1_3440.html
Here's what I had calculated based on the NGA Rocket Launching notice:
Primary Day = Saturday, March 13 at ~10:06 UTC.
Backup Day = Sunday, March 14 at ~09:44 UTC.

The switch to daylight savings here in the states is Saturday into Sunday, I would presume the back up day would be more like 08:44 UTC, here in Florida it will be UTC -4 with the change, which would be 4:44 am local.

= Sunday, 14 March ~5:44 am EDT. (EDT = UTC - 4 hours)
(UTC doesn't shift for daylight savings or summer time. The affected time zone does. It's one of the several reasons to
love UTC.) 💘

Gotcha, thought it was the other way around because I thought starlinks got around 20 minutes earlier per delay day.

Gotcha, thought it was the other way around because I thought starlinks got around 20 minutes earlier per delay day.
The mid-inclination Starlink launches get a shade over 21.5 minutes earlier each day in absolute terms, so that's reflected in the time in UTC regardless of an time change.
If there is a time change, local time will be 38.5 minutes later for Spring Forward (what is shown in zubenelgenubi's calculations) or an hour and 21.5 minutes earlier for Fall Back.
