Biarri-Point is quite a mystery, as it has been claimed to be deployed, but has not been catalogized. I am not sure, if it has been indeed deployed. Perhaps it was to be deployed and was left stuck in the deployer. Or it remained stuck to another cubesat and has a shared ID with this one.

Biarri-Point has been deployed. At the South Australian Space Forum on 7 June, a defence presentation mentioned that it had been deployed from ISS on 18 May and was being tested before the payload was turned on. They even showed a photo of it in orbit. I don't know why it hasn't been catalogued.

Maybe the mistery of Biarri-Point is solved?

Here's the official Australian press release.

https://www.minister.defence.gov.au/minister/christopher-pyne/media-releases/australian-defence-delivers-world-first-gps-cube-satellite

It points to these images from the Australian defence.

Found some other images of Biarri-Point. This matches the SHARC cubesat. Attached is image showing SHARC being ejected from ISS.

https://www.nasa.gov/mission_pages/station/research/experiments/1350.html

SHARC was deployed on 17 May.

Issue resolved. Pushing for rollout soon. [Static fire] Window opens 8am local.

Anyone willing to share info on the 'issue', or is this a subtle advertisement for L2 ;)

Is this a block 4 F9? If so what are the improvements vs B3?

From the best that I can gather, the term Block III/IV/V is a bad way to name it.
SpaceX isn't rolling all Block IV or Block V features in a single step. Its a gradual process. And I doubt SpaceX will want to tells us exactly what's in or not, except maybe as L2 type off the record discussions (yes there are some, if you really want to know everything you can, you need L2 access).
At some point Elon is likely to say all Block IV features to booster and US have been rolled in, but at that point the first Block V features will be in too, should we call that a Block IV or a Block V ? In my view the real Block V is when all planned features are in, not when just a few are.
That's all you'll get from me, as I don't want to loose L2 access !

Station-bound instrument to open new chapter in the story of cosmic rays

Quote
Physicists are gearing up to send a re-engineered science instrument originally designed for lofty balloon flights high in Earth’s atmosphere to the International Space Station next week to broaden their knowledge of cosmic rays, subatomic particles traveling on intergalactic routes that could hold the key to unlocking mysteries about supernovas, black holes, pulsars and dark matter.

Fastened in the cargo bay of a SpaceX Dragon capsule, the cosmic ray observatory will be robotically connected to a port outside the space station’s Japanese Kibo laboratory for a three-year science campaign sampling cosmic rays, particles accelerated to nearly the speed of light by violent and mysterious forces in the distant universe.

This is the first Block 4 first stage. Block 4 second stages have been flying for some time now.

We’ve heard about thrust upgrades and things like bolted octawebs, but nothing super concrete.

It’s basically just a bunch of small hardware upgrades they threw together on their way up to Block 5. We probably wouldn’t even notice the upgrade, especially considering we didn’t notice the Block 2 and 3 upgrades.

I've been assuming that block 2 was the v1.1 and block 3 was the v1.2. I'm going to be interested to see if the launch permits call the block 4 the v1.3.

They won’t.

They’ve flown v1.2 Block 1, v1.2 Block 2, v1.2 Block 3, and v1.2 Block 4 all under the same permit for “Falcon 9 v1.2”

you will notice some of the block 4 differences if you have a good eye and watch the flight footage and not all are small differences but most are. I'll leave you with that until launch day.

Not sure if this a concern or not: loss of redundancy for ISS S-band transponder string.
From ISS Expedition-52 thread.
Added bold.


ISS Daily Summary Report – 8/09/2017

Posted on August 9, 2017 at 4:00 pm by HQ.
 

...

Remote Power Controller Module (RPCM) P12B_B Trip: This RPC powers the S-Band transponder for String 2. There were no impacts to voice or telemetry as S-Band String 1 was and continues to be prime. String 2 was in hot backup for ACS/UHF Audio Interface (AUAI) troubleshooting. The trip signature indicates a Field Effect Transistor (FET) Hybrid failure which would be the first occurrence for this RPC.  Multiple closure attempts of RPC 10 were performed with no success. Two fully functional strings of ISS S-band are required per the SpaceX Launch Commit Criteria (LCC) Flight Rule. Teams met this morning to discuss and recommend a forward plan. This is an external RPCM that can be Removed and Replaced (R&R) by the Special Purpose Dexterous Manipulator (SPDM).

This is in the August 10 report:
Quote
Ku Band Contingency Command and Telemetry (CCT) Checkout: In response to the loss of S-Band redundancy due to the loss of power to the S-Band-2 transponder, ground teams completed a checkout of the Ku-Band CCT command and voice capability.  During the test all control centers, including Sp-X Mission Control, successfully sent test commands to ISS via Ku-Band.  Additionally, Ku-Band voice between ISS and MCC-Moscow was verified in the event this is needed during the upcoming Russian Extra-Vehicular Activity (EVA).

L-3 Launch Weather Forecast.
70% go for launch day
80% go for 24 hours scrub

I see 70% for both days.

Very curious. I see 20% POV in forecast on-line at:

Thanks. Yes they updated & appear to have forgotten to update time of issue.

When I did my previous post the 45th's weather page pointed to the old (20%) version but as you say it's now showing the new (30%) version.
