Discussion thread for Starlink v1.0 Launch 26

NSF Threads for Starlink v1.0 L26: Discussion
NSF Articles for Starlink v1.0 L26: https://www.nasaspaceflight.com/2021/05/spacex-starlink-rideshare-milestone-nears/

Launched successfully 15 May 2021 at 6:56pm EDT (2256 UTC) on Falcon 9 (booster 1058.8 ) from KSC LC-39A. ASDS landing achieved on OCISLY, towed by tugboat Mr. Jonah. Recovery support ship was GO Quest. Fairing recovery of one half from the water by MV Shelia Bordelon.

Payload: A batch of 52 Starlink satellites plus 2 rideshares. Expected deployment orbit of approximately 575km circular.

Rideshare passengers are Capella-6 (Whitney-4) and Tyvak-0130.

Quote
SpaceX is targeting Saturday, May 15 for its next Starlink mission launching aboard Falcon 9 from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The instantaneous window is at 6:54 p.m. EDT, or 22:54 UTC, and a backup opportunity is available on Sunday, May 16 at 6:33 p.m. EDT, or 22:33 UTC. On board this mission are 52 Starlink satellites, a Capella Synthetic Aperture Radar (SAR) satellite, and Tyvak-0130.

The Falcon 9 first stage booster that supported this mission previously launched NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and three 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. One half of Falcon 9’s fairing previously supported the SXM-7 mission, and the other previously supported the NROL-108 mission.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

From a previous mission's Press Kit:
Quote
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.

It could be referring to a different mission but SpaceX has used "Starlink-xx" nomenclature in an STA request for the first time (that I'm aware of) :) "Starlink-26" is NET May 13th.

I’m wondering if there is something uniquely specific to this STA that is preventing them from using a RF mission STA instead, thus forcing Starlink L27 to launch first.

Or it could just be a rideshare payload issue.

Capella got their FCC license to launch two satellites today.  I'm guessing it may be on this flight?  If so it will go to a higher orbit (575km) and carry fewer Starlinks along with the two Capella sats.

Quote
Overview:Capella 5&6 will be launched no earlier than April 2021, on a 53degorbit at an altitude between 550km and 600km.  For the purpose of this document, the worstcase altitude in terms of lifetime of 600 km will be used.
...
Launch:Capella 5&6 are currently planned to be launched on a SpaceX Falcon 9 rocket,no earlier than April 2021.Mission Duration:Maximum Nominal Operations:  3 years, Post-Operations Orbit life-time:  less than 3 years until reentry via atmospheric orbital decay (worst case less than 6years in total).

Orbit Profile:Capella 5&6 will deploy from the launch vehicle into a near-circular 53deginclined orbit at an altitude of 575 km.  They will maintain an altitude between 475 and 600km using a RF xenon propulsion system for 3 years.2. 

Physical Description of the Spacecraft:Capella satellites have a launch mass between100 kg and 120 kg.  Two 500mm x 900mm deployable solar arrays, a 8m2deployable antenna and a 3m long boom deploy from the principal bus structure.

Another Starlink mission is planned in mid-May with a Falcon 9 launch from pad 39A.

Likely this mission

The only two boosters available in mid May would be B1058 and B1063, unless another record turnaround occurs.

That TFR is probably for Starlink L27, which appears to be launching ahead of L26.

We know that the shared mission of Starlink seems that it will not be L26, however, I contacted Predasar and they told me that the launch of their satellite will be at the end of this year, there is no launch date yet.

We know that the shared mission of Starlink seems that it will not be L26, however, I contacted Predasar and they told me that the launch of their satellite will be at the end of this year, there is no launch date yet.

I don't know what the ride shares are on this flight.
However I will remind you of the following:

Starlink v1.0-L08 flew with 3 Skysat birds as ride-share.
Starlink v1.0-L09 flew with 2 Blacksky birds as ride-shares
Starlink v1.0-L10 flew with 3 Skysat birds as ride-shares

Each of those flights were with less than 60 starlink satellites.
I forget the reduction but it was something like 3-5 starlink sats.
