This launch has appeared on CADENA OIS...however the launch dates and windows are almost exactly the same as for the delayed Group 12-25 (some days listing with exactly the same window, and others with 1 minute of differences), so either that or this 12-10 will launch NET March 16 and we'll have to wait to see which one will go first.

The attached document shows this as launching from CCSFS = SLC-40.

Primary Launch Day 16 MAR 1905Z-2336Z Backup Launch Day (1) 17 MAR 1837Z-2308Z Backup Launch Day (2) 18 MAR 1810Z-2241Z Backup Launch Day (3) 19 MAR 1742Z-2213Z Backup Launch Day (4) 20 MAR 1714Z-2145Z Backup Launch Day (5) 21 MAR 1647Z-2118Z Backup Launch Day (6) 22 MAR 1619Z-2050Z

Bump

There has been no further information about this launch.

Starlink 6-80 appeared today, and apparently, on March 30 UTC, will be the last March Florida Starlink launch scheduled; pushing Starlink 12-10 into NET April.

Edit March 28: Starlink 6-72 follows, scheduled for April 6 UTC.

12 days since the last DtC Group 12 launch and nothing on the near term manifest.

V2.0 Mini's have no transitioned to the V2.0 Mini enhanced.  So perhaps DtC is transitioning also to the the V2.0 Mini Enhanced buss and we are witnessing production delays?

After disappearing for 1 month, this launch has reappeared on CADENA OIS:

Primary Launch Day 29 APR 0137Z-0608Z Backup Launch Day (1) 30 APR 0109Z-2308Z Backup Launch Day (2) 01 MAY 0041Z-0512Z Backup Launch Day (3) 02 MAY 0014Z-0445Z Backup Launch Day (4) 02 MAY 2346Z-0417Z Backup Launch Day (5) 03 MAY 2319Z-0350Z Backup Launch Day (6) 04 MAY 2251Z-0322Z

Edit: Ben Cooper shows the launch as switching to pad 39A.

A Falcon 9 will launch a Starlink batch from pad 39A on April 28 earliest at 9:37 p.m. - 1:37 a.m. EDT.
