Remember how we talk about space weather and geomagnetic storms and how they can affect our satellites in orbit… update on the #Starlink satellites launched last week, lost to a geomagnetic storm on Friday.

We've been noticing the lack of orbit updates for the most recent batch of Starlinks, and the reentry of several. Well, it turns out things did not go well for this launch. SpaceX now say increased drag due to a recent geomagnetic storm forced them to put the sats in safemode but..

GEOMAGNETIC STORM AND RECENTLY DEPLOYED STARLINK SATELLITES

FEBRUARY 8, 2022

On Thursday, February 3 at 1:13 p.m. EST, Falcon 9 launched 49 Starlink satellites to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. Falcon 9’s second stage deployed the satellites into their intended orbit, with a perigee of approximately 210 kilometers above Earth, and each satellite achieved controlled flight.

SpaceX deploys its satellites into these lower obits so that in the very rare case any satellite does not pass initial system checkouts it will quickly be deorbited by atmospheric drag. While the low deployment altitude requires more capable satellites at a considerable cost to us, it’s the right thing to do to maintain a sustainable space environment.

Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday. These storms cause the atmosphere to warm and atmospheric density at our low deployment altitudes to increase. In fact, onboard GPS suggests the escalation speed and severity of the storm caused atmospheric drag to increase up to 50 percent higher than during previous launches. The Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag—to effectively “take cover from the storm”—and continued to work closely with the Space Force’s 18th Space Control Squadron and LeoLabs to provide updates on the satellites based on ground radars.

Preliminary analysis show the increased drag at the low altitudes prevented the satellites from leaving safe-mode to begin orbit raising maneuvers, and up to 40 of the satellites will reenter or already have reentered the Earth’s atmosphere. The deorbiting satellites pose zero collision risk with other satellites and by design demise upon atmospheric reentry—meaning no orbital debris is created and no satellite parts hit the ground. This unique situation demonstrates the great lengths the Starlink team has gone to ensure the system is on the leading edge of on-orbit debris mitigation.

Revised plot showing deployment altitudes of Starlinks (top panel: perigee blue, apogee red); atmospheric density (middle panel)  at 200 (red), 220 (blue), 250 (green) km altitude, and solar radio flux (lower panel).  Density from NRL-MSISE00 model using Kelso solar data..

This is the "geomagnetic storm" batch that launched on 3rd Feb, "group 4-7". It is the 38th launch counting them all sequentially but wikipedia lists it as #36 because it did not number the two "polar orbit" launches.
