The first commercial airlock is heading to the International Space Station later this year
2

Nanoracksí Bishop airlock is slated to fly on SpaceXís next cargo mission

By Loren [email protected]  Sep 15, 2020, 5:06pm EDT

Later this year, SpaceXís Falcon 9 rocket will take off from central Florida, carrying a large metal cup destined to be attached to the outside of the International Space Station. The hardware is a first-of-its-kind commercial airlock, designed to get payloads and other materials from inside the pressurized space station out into the vacuum of space.

Yesterday, @BoeingSpace completed the PCBM installation. #BishopAirlock, you are looking mighty fine.

KSC-20201007-PH-KLS01_0063

Nanoracks technicians work on the NanoRacks Bishop Airlock inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida on Oct. 7, 2020. The next-generation Nanoracks payload facility is being prepared for its flight to the International Space Station on SpaceX's 21st commercial resupply services mission (CRS-21) to the International Space Station. The Bishop Airlock is the first commercially funded airlock for the space station. It will provide payload hosting, robotics testing, satellite deployment, serve as an outside toolbox for station crew spacewalks, and more. CRS-21 is scheduled to launch on a SpaceX Falcon 9 from Kennedy's Launch Complex 39A.

#BishopAirlock News: @esa  has pre-purchased five airlock cycles, and @NASA six, with an option for four additional cycles at a discounted rate. Read our announcement here: http://nanoracks.com/bishop-airlock-nasa-esa-purchase #ISS

That kind of was to be expected. But still very nice news.
The Nanoracks Bishop Airlock and (Airbus) Bartolomeo External platform combined, extend the external utilization capability a lot. The bishop airlock makes it possible to launch external payloads pressurized, and return external payloads. That capability was lost when the spaceshuttle was retired. Bartolomeo (8-12) and Bishop (6) combined add 14 to 18 GOLD2 external payload slots. I think multiple GOLD2 payloads can be transferred with each Bishop airlock cycle.

I don't think I've seen this NanoRacks patent from a few months ago discussed https://uspto.report/patent/app/20200156810

Looks like they're considering Bishop follow-ons (likely in the form of additional cylinder segments between Bishop itself and ISS) for FRAM-mounted payloads and human EVA. The human EVA part is interesting as previous official diagrams showed them favoring a stretched single-piece airlock for humans

Bishop + this cylinder extension would not be able to clear the radiator berthed at the end of node 3. It would need to move somewhere else to be stacked. In the diagram's case that is BEAM's current berthing port.

I wonder if Biglow's financial issues affect BEAM's future. It was previously reviewed for the capability to extend its mission into 2028+.
Per the patent info and attached concept graphics show Bishop extensions would berth in the example to where BEAM is and BEAM would either be jettisoned or relocated to N1N or a future module. The extensions could be installed at many ACBM locations. Other existing capable locations include N1N, N2F, N2Z, N2N, N3F, N3A, and N3N. Note that one version in the document is a rehash of their NR LUNA Module (Lightweight Urthecast NanoRacks Alcove), that was shelved when BEAM was assigned N3A, by replacing GOLD interface Urthecast hardware with a 7 AFRAM. With LUNA losing its slot to BEAM the A/L function became Bishop which responded to the RFP for a commercial module whilst providing critical Node 3 endcone ACBM MMOD protection. This patent builds upon their patents for LUNA and Russian projects.

Early design (graphic shown predates the switch from GOLD[1] to Active FRAM's) Nanoracks LUNA Module archival info: https://space.skyrocket.de/doc_sdat/luna.htm

Interesting idea, but a possible issue with putting it on Node 3 Aft port would be clearances with the semi-stowed FGB solar array. I wonder if there's any way they could retract it some more...

as with Mir and predecessor station modules some were designed to be relocated and others ejected via EVA and arm or replaced. I'm not sure of Zarya's capabilities. I know the drive motors and other motors were disconnected from power and data circuitry however I seem to vaguely recall several iterations of a plan to remove and return them on Shuttle for now cancelled RS modules and later as a back-up set for now MLM-U. There was also at one time a graphic showing Zarya's arrays being moved to Nauka before departure under early DAC for the OPSEK ROS proposal.

It seems extraction and relocation of the Nanoracks Bishop airlock will take place from 23:20 to 2:20 UTC tonight.

Quote
About 4 hours until this happens! Itís installation day for the Nanoracks Bishop Airlock onto the  International Space Station and her new home on Node 3 @ Nanoracks

For all you Airlock super fans out there, some more details:
1. We hope some of it will be broadcast on NASA TV but not sure. 🤞
2. Grapple by the SSRMS (robot arm) around 5:20 central time
3. Total process will take about 3 hours
4. No Airlock activation tonight 😢. Later..

It might be webcast here:

iss064e013203 (Dec. 20, 2020) --- The NanoRacks Bishop airlock is pictured after its was installed to the port side of the Tranquility module and still attached to the Canadarm2 robotic arm. Adjacent to Bishop on the aft side of Tranquility is BEAM, the Bigelow Expandable Activity Module. Bishop increases the stationís capacity for private and public research and also enables the release of larger satellites and the transfer of cargo inside and outside the station.

In this photo you can see the CBCS* target installed across Bishop.

*Centerline Berthing Camera System - a camera looking through the CBM hatch porthole used to guide modules into position during berthing, which uses the target as an alignment guide.

I asked Brock Howe (@B_Rock_Howe), Nanoracks Bishop program manager, on Twitter about how this will affect satellite deployments from Bishop, his response was interesting:

Quote from: @Space_Pete
I'm wondering how cubesat deployment from Bishop will work with the CBCS reflector in the way?

Quote from: @B_Rock_Howe
Good question!  The CBCS target is only used for this initial berthing. The target will be removed by the crew after hatch opening. During this first berthing, the robotics team took joint angle measurements at various waypoints on the way to getting us to Node 3. On subsequent Airlock sorties, the robotic team will fly the arm to these waypoints to bring us back home again.  Pretty cool stuff by the Canadarm2 and the ISS robotics ream!

This is another innovative first for the ISS program I believe!


I also asked him about Bishop depressurisation:

Quote from: @Space_Pete
How will Bishop depressurisation work? Will you connect up to Quest airlock pump via extension hose to recover any air into ISS? I presume Bishop has its own electrically-operated depress valve?

Quote from: @B_Rock_Howe
NASA developed an air save pump called the Pressure Management Device that connects to the Node 3 hatch equalization valve. It will pump the air out of Bishop Airlock into Node 3 down to about 1 psi. The last 1 psi is vented overboard via the PMD. To pressurize the Bishop Airlock , the equalization valve and a valve in the PMD are opened to naturally let the air flow into the Airlock. There are stopping points at various pressures to perform leak checks to ensure crew safety prior to hatch opening and crew ingress.

Here's some good info on the GOLD2 connectors used on Bishop (also used on MISSE-FF and Bartolomeo).
