Discussion thread for Starlink v1.0 L20

NSF Threads for Starlink v1.0 L20: Discussion

Successful launch March 11, 2021 at 3:13 am EST (08:13 UTC) on Falcon 9 (booster 1058-6) from SLC-40. Successful ASDS landing on JRTI. Fairing recovery is expected.

Payload: A batch of 60 Starlink satellites. Expected deployment orbit of approximately 250x280km.

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

Check the Starlink Index Thread for links to more Starlink information.

L2 SpaceX:
https://forum.nasaspaceflight.com/index.php?board=60.0

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.

Will this actually fly in February?

If so it will be only the second time that SpaceX launches 4 times in the same calendar month.

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 Apr 3.

5 launches in Feb still a possibility!!!!!!

ASDS availability seems to be limiting right now too.

For a Starlink to Starlink launch on the same pad both the pad cycle minimum and the ASDS cycle minimum seems to be about 8 days. At least they keep trying for that interval. But the actual seems to be keep being at ~11 days mostly due to weather. Which would put a nominal date for L20 of ~Feb 26. Also note that the probable boosters would have a cycle time of 37 days for 1051 and 33 days for 1058. Not even pushing it for either. SpaceX will likely choose whichever booster is the first to be ready to go. Which could be 1058 vs the larger cycle span time for 1051. It is a matter of which booster needs the least amount of issue corrections or checks.

In this case, the T0 on February 25th should be ~09:48 UTC (4:48 AM EST).

That notice is for second stage reentry, not launch

<snip>
Approximately 1 1/2 orbits from launch to re-entry.

Approximately 90 minutes for a Low Earth Orbit.

Re-entry is approximately 135 minutes after launch. (90+45)

Subtracting 135 minutes from ~09:35 UTC ~= 07:20 UTC launch time.

It takes several minutes to accelerate from 0 to orbital velocity, so the actual re-entry time would be several minutes later. Somewhere around 02:30 07:30 UTC.  = 02:30 EST.

Edit: Fixed final answer--mislabeled EST time as UTC time.

Given that LC-39A will be occupied until the currently date-TBD Starlink launch occurs, I expect that this launch will go from SLC-40.
I think so. I don't know so.

SpaceX believes they can do a 8 day L2L on LC-40. The last one was in actuality even with several weather delays an 11 day L2L. A 10 day for them is a more reasonable time for L2L and is not likely to represent any problems other than for the #1 item being weather and now the #2 item being an understanding and possible inspections or corrections due to 1059 landing failure.

Following this:
Active NOTAM in MELBOURNE information region for Stage2 reentry of Starlink_v1.0-L20 mission with primary date planned NET February 25 in window between 09:33-10:30 UTC, backup dates February 26 to March 01.
Reentry area south of Australia is typical for flight profile with double S2 burn and circular deploying orbit.
<snip>

We now have this:
Mission was postponed to NET 08 March [0445 to 0722 UTC], alternatively 09 March [0424 to 0701 UTC], based on NOTAM update in MELBOURNE information region for Stage2 reentry.
<snip>

Also, March 8 is 11 days later than February 25.  Given the launch time is 20-22 minutes earlier each day for this inclination of Starlink launch, the launch time is roughly 4 hours earlier.
March 8, ~03:30 UTC = March 7, ~22:30 EST.

Or, one can use the calculation method here.
***

Edit/Also:
First stage will be 1058.6.

Static Fire or not to Static fire?

With the recent loss of booster 1059 I'd bet they do Static Fires on all vehicles for sometime.

Tug Finn Falgout will tow JRTI ~633km downrange. They will likely pass OCISLY and B1049 at sea. 😄

Just an FYI - the link to the discussion at the beginning of this thread (L20) sends one to the discussion of L19.

I'm looking to find out if they will be broadcasting from the booster on L20.

SpaceX tweet & update :)

https://twitter.com/SpaceX/status/1369100478831677440

Quote
SpaceX is targeting Tuesday, March 9 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 9:58 p.m. EST, or 2:58 UTC on March 10.

The Falcon 9 first stage rocket booster supporting this mission previously supported launch of NASA astronauts Bob Behnken and Doug Hurley to the International Space Station, ANASIS-II, CRS-21, Transporter-1, and a Starlink mission. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing previously flew on the ANASIS-II and SXM-7 missions, and the other half previously supported launch of Sentinel-6A.

I didn't see a tweet from SpaceX yet, and it's been a half hour since.

Either way, it doesn't make sense why three hours before launch even when there's good weather.

New weather forecast.  The PDF file name has L-1 (and I named the image file to match as usual) but it should be L-2.  80% 'Go' for both days.

And since I'm posting anyway, here is what I calculated for the additional launch times.  I didn't include these when I posted the NGA notices that added the additional launch times because I hadn't done the calculations yet.

Primary Day = Thursday, March 11 at 08:13 UTC.
Backup Day #1 = Friday, March 12 at ~02:15 and ~07:51 UTC.
Backup Day #2 = Saturday, March 13 at ~01:54 and ~07:30 UTC.
Backup Day #3 = Sunday, March 14 at ~01:32 and ~07:08 UTC.
Backup Day #4 = Monday, March 15 at ~01:10 and ~06:47 UTC.

I don't know.
Are you referring to the grayscale video in the left window circa T+4 minutes?
Edit: yes, that's the coverage I referred to.

Yup. I attached screenshots above.  Just after re-entry burn they also seemed to switch feeds very briefly and you could see the same star.

The static photos don't do it justice, but you could see the "nebula effect" flowing from what I assume was the second stage engine.

Funky music on the SpaceX feed as the second stage and payloads continue on the initial orbit.

We're waiting for the orbit circularization burn.

No, thermal infrared ground tracker footage. The same one they used during ascent - which, coincidentally, showed the top of the fairing getting brighter due to aeroheating.

B1058-6 launched Starlink M20 from LC-40 at Cape Canaveral SFS sending another 60 satellites into orbit. This mission features a veteran booster and veteran fairing halves. The booster landed on JRTI 634km downrange. Psst: reentry🔥

Looks like they have that trajectory dialed in.

I still have a hard time believing just how routine the whole process of launching 60 satellites and reusing the booster and fairing have become.  What an age to live in.

Since they're planned water landings, I'm sure they did.  What kind of shape they'll be in, we'll have to wait and see.  Sea conditions were low risk, so I expect they'll be reuseable, but like I said, can't tell until they get in port.

Have a good one,

Wait till the fill the shell in what 6 launches? Then they switch to the 70 degree and 97 degree shells.

The trajectories, they will be a chang'in.

Sounds like a reason why they wanted to open up the polar flight path form the east and ramp up west coast operations.

#SpaceXFleet update:

Finn Falgout/JRTI/B1058 has not had an AIS ping. (This is normal- ghost tug I tell ya)

Hawk/OCISLY are well on their way going 7 knots towards the Starlink LZ.

Fairing scoopers Searcher/Navigator are almost to Morehead City to drop off their haul.

Finn Falgout, Just Read the Instructions and B1058-6 have arrived at Port Canaveral after the Starlink L20 mission.

The Space Coast woke up to a launch and spring breakers are being suprised by the arrival of a scorchy booster.

GO Pursuit will be arriving at Port Canaveral with the fairing from the Starlink V1 L20 mission in about 60 minutes.

GO Searcher/Navigator successfully recovered them during the mission and transferred them to Pursuit in North Carolina on Friday.

B1058 is going horizontal so that they can move on to processing B1051 today. This is the sort of traffic jam we don't mind seeing at the docks.
