January 2022 on Falcon 9 from SLC-4E VAFB to polar orbit.  First stage is xxxx-x, landing at LZ-4.

 SpaceX wins $150 million contract to launch Space Development Agency satellites (https://spacenews.com/spacex-wins-150-million-contract-to-launch-space-development-agency-satellites/)
Quote from: Sandra Erwin
SpaceX has been awarded a $150.4 million contract to launch as many as 28 satellites for the Pentagon’s space agency, the Defense Department announced Dec. 31.

The contract is to launch a mix of small and medium spacecraft of different sizes that the Space Development Agency is acquiring from multiple vendors. That includes 20 data-relay satellites known as the Transport Layer and the other eight are missile-warning satellites known as the Tracking Layer.

It would be, except:

1) The mass of 14 SVs and the polar orbit likely means there will only be room for smallsats

2) There are only two launches for tranche 0

3) The first launch is September 2022, so a bit too far out considering SpaceX wanted to start the first polar shell in December 2020.

Not to be contradictory but I thought the 4 SpaceX sats in Tranche 0 are Starlink bus derivatives. If they aren't Starlink derived, then 'SpaceX has a new Satellite Bus' would seem to me to be way more important news than a couple of essentially ride share launches. Of course Jensen shot down my original idea but I would be interested if this is a new bus

Just because they are Starlink derived doesn’t mean that they are the same as Starlink satellites.

Thanks guys!

This makes me think the permission to have other ride shares along with this mission was more about establishing the legal status/flexibility than any actual intent to do so. Seems there isn't any berths available in the stack for them to sell. I can see SpaceX wanting to establish launch services as legally equal to any other common carrier. I had not expected the military to take this baby step until ordered to by congress budget. Good news all around

Don't expect commercial ride share payloads. More likely any available ride share options on these launches will be used for the Space Test Program or other military programs.

The eight satellites make up the Tracking Layer Tranche 0. The first Tracking Layer launch, projected for September 2022, is likely to include at least two SpaceX satellites. The second launch, planned for March, will include all four L3Harris satellites and others from the Transport Layer Tranche 0, which are being produced by Lockheed Martin and York Space.

I think it is important to accept the fact that space flight isn't just all a nerdy quest for knowledge.  This isn't Star Trek.  There is a reason why we have missile tracking and missile intercept systems.  The world isn't all rainbows and unicorns.  We have identified our biggest threats and we don't look at them as our brothers in humanity.  I have worked on missile defense technology for a long time and I can tell you that the DOD is VERY worried about hypersonic missiles right now.  This is a VERY important mission. 

We should discuss these realities along with the purely nerdy side of spaceflight.  In that vein, I think the DOD made a major mistake in locking SpaceX out of Tranche 1.  For all the good work that Lockheed and Northrop do, they have been slow and over budget on just about everything they have done lately.  Missile defense is too important and too urgent.

Space Development Agency still hoping to launch satellites next month, ‘but there’s risk’ (https://spacenews.com/space-development-agency-still-hoping-to-launch-satellites-next-month-but-theres-risk/)

Quote from: SpaceNews
The Space Development Agency remains optimistic it will launch next month the first satellites of a planned mesh network of sensors and communications nodes in low Earth orbit, the agency’s director Derek Tournear said Nov. 10.

“We have high confidence … but there’s obviously risk there because we are pushing industry to go as quickly as possible,” he said on an online forum hosted by the National Security Space Association.

<snip>

The satellites trying to make the December launch are “in integration right now, doing last minute finishing touches, putting the payloads on the satellites,” he said. “There was some ground software that we actually had to change.”

Next Spaceflight is listing booster B1071.5 for this launch.

https://nextspaceflight.com/launches/details/5657

It has been doing so since it was originally scheduled for the end of September:

SDA Tranche 0 Flight 1 on NextSpaceFlight (https://nextspaceflight.com/launches/details/5657), updated August 3:
First stage 1071.5, landing at LZ-4.

Given that B1071 has already made it's fifth flight, it would be at least on it's sixth flight if B1071 is still scheduled to launch this mission.

Ah, good catch. I guess it hasn't been updated since the delay.

Oops that was probably my fault. Booster was eventually moved to another flight. I'll delete it since the booster assigned to it is likely a different one now.
