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

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'm going to be interested to see if the launch permits call the block 4 the v1.3.
After landing Monday, storm chances will increase, potentially impacting first stage securing.
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)....
Not sure if this a concern or not: loss of redundancy for ISS S-band transponder string.From ISS Expedition-52 thread....
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).
Interesting comment in the launch weather forecast:QuoteAfter landing Monday, storm chances will increase, potentially impacting first stage securing.

For the year-long experiment, astronauts will install the computer inside a rack in the Destiny module of the space station. It is about the size of two pizza boxes stuck together. And while the device is not exactly a state-of-the-art supercomputer—it has a computing speed of about 1 teraflop—it is the most powerful computer sent into space. Unlike most computers, it has not been hardened for the radiation environment aboard the space station. The goal is to better understand how the space environment will degrade the performance of an off-the-shelf computer.During the next year, the spaceborne computer will continuously run through a set of computing benchmarks to determine its performance over time. Meanwhile, on the ground, an identical copy of the computer will run in a lab as a control.If the test is successful, it will open the door to the use of even more powerful computers aboard the space station and other spacecraft NASA is developing to send humans farther into space. Fernandez said HPE also envisions that scientists could eventually use an on-board supercomputer for data processing of their experiments on the station, rather than clogging the limited bandwidth between space and ground with raw data.
