Where is this located?
https://en.wikipedia.org/wiki/Bishop_Airlock_Module
Apparently this is being launched on the next Dragon flight. But I'm curious where it will be berthed. Anyone know. |

Endcap of Node 3 apparently. Reference 4 in that article leads to an arstechnica article with more detail. Anthony |

Picture shows it attached to the axial CBM on a Node: http://nanoracks.com/nanoracks-adds-...ce-to-airlock/ It's the dome shaped thing on the axial CBM port. That's really all it is. You open the CBM hatch, load this thing up with nano-satellites, close the CBM hatch, undo the CBM attachment (motorized bolts), then use the SSRMS to grab the dome shaped thing and aim it the other way for satellite deployment.

Jeff I suppose I should read the article. What's the advantage of being able to do that from the ISS? Last minute reconfigurations of the satellites? Retreival of satellites after exposure to space?

I honestly have no idea what the advantage is. This is only for deployment. Retrieval has not been done, as far as I know. The Russians just take them outside with the crew on an EVA and deploy them by hand. The US has this fancy deployment mechanism. I believe that the Japanese lab module also has a deployment mechanism for smallsats. So I'm not really sure what the "need" is for this US system.

These are ride-shares organized directly by Arianespace and SpaceX. If I want to send my iPhone in orbit as a "small sat", wouldn.t I get a better deal going with NASA which likely subsidizes such endeavours for people it likes vs having to buy a launch from SpaceX or ArianeSpace? That's my point. Why should the US Government be subsidizing the smallsat industry? NASA should be working on innovating and pushing bleeding edge tech. Smallsat launch is not that. It is easier to pack such a device in a box/pallets to be launched to ISS on Dragon/Cygnus/Progress, and then launchy it out of that airlock rather than having to deal with SpaceX/Ariane to get the specs for the luanch interface and do all the paperwork for a single little device. (if you're sending 60 cobesats, things would be different). If you think NASA paperwork would be a picnic, I've got a bridge to sell you. Actually, the size of cubesats have been standardized for quite some time. There are also standard cubesat launchers as well. Atlas V announced its entry into this space years ago: ULA Making Cubesat Dispenser Standard on all Atlas 5 Rockets by Mike Gruss - November 23, 2015 https://spacenews.com/ula-making-cub...andard-on-all- atlas-5-rockets/ As for Cygnus, you can hitch a ride directly on the Cygnus. No need to go inside ISS: External Cygnus Deployment http://nanoracks.com/products/extern...us-deployment/ And I haven't even mentioned the dedicated smallsat launchers like Elektron and the like. Again, I see *zero* reason for NASA to be doing this on ISS. It's not pushing tech in any way and it's clearly directly competing with private industry.

NASA can do this by grants to research and educational institutions. NASA doesn't need to be in the smallsat launch business. The US Government should not be in direct competition with private industry like this. It's b.s. If you think NASA paperwork would be a picnic, I've got a bridge to sell you. I suspect that when NASA chooses some educational instiutution for some experiment on ISS, the paperwork is done by NASA PAO because they want the good PR from those projects. You suspect? How about a cite instead? Again, I see *zero* reason for NASA to be doing this on ISS. Do any of the small launches from ISS remain in communications with ISS for the experiment? (aka: experiment monitored by ISS crews)? That could be an advantage of an ISS launch vs launch on a rocket. I don't know for sure, but I'm guessing not. Their orbits will diverge from each other, so it's going to be hard for ISS to monitor a smallsat that's literally on the other side of the planet. The fact that NASA wants this capability and the Japanse lab is at capacity for such launchs points to there being a need for ISS operations to launch such objects. I never said there wasn't a need. But why does the US Government have to provide this service when there are literally dozens of start-up smallsat launchers being developed in the US? Why should the US Government take market share away from a growing market where US companies are trying to compete (and drive down prices)? I'm sorry, but this is entirely ass-backwards. When the shuttle was planning to fly educational payloads, it made sense because there were precious other ways for such payloads to fly. But this is now 2019 not 1979. And yesterday, Rocketlab just announced that they're going to attempt to recover and reuse Electron first stages: Rocket Lab to attempt to reuse Electron first stage by Jeff Foust - August 6, 2019 https://spacenews.com/rocket-lab-to-...lectron-first- stage/ This is *exactly* the sort of commercial innovation that NASA is undercutting by offering subsidized rides.

I believe that the Japanese lab module also has a deployment mechanism for smallsats. The USA *doesn't* currently have independent capability, they get half the openings of the Japanese airlock (12 a year limit so 6 available) to put stuff outside. Smallsat launches have to share with experiments using the JEM exposed facility which is creating a bottleneck. This new 'airlock' will allow more launches more frequently. Anthony |
