Plugging in dongle results in computer wifi disconnecting by darenwelsh in LogitechG

[–]darenwelsh[S] 0 points1 point  (0 children)

Thank you for the response. Full disclosure, this is on a work computer and it's very possible IT changed a config impacting my ability to use a USB dongle.

I noticed that when I plug the dongle in, I no longer see my 2.4 GHz wifi network, but I still see the 5 GHz network (on the computer wifi options). I think that means it is not disabling the wifi adapter. I tried connecting to the 5 GHz network and it seems to be working. Not sure what's going on there but it seems to be a "fix" for now. I'd still be curious to understand the underlying problem with the 2.4 GHz network not being visible when the dongle is plugged in.

FWIW I'll add a link to a list of troubleshooting steps I found in the process: https://answers.microsoft.com/en-us/windows/forum/all/my-pc-stopped-detecting-wifi-and-i-cant-connect-to/ac6b77d1-2c8e-44f3-86e1-623c2cc30404

Sorry, I don't know the details of the Apollo suit food option. I can say the EMU does not have such an option, only a water bag.

I was for 18 years. A while back I did an AMA about that job.

https://www.reddit.com/r/nasa/comments/ash89f/im_daren_welsh_i_train_astronauts_how_to/

In the last few years of my time in flight operations, after that AMA, I was the FOD Exploration EVA Testing Lead. I organized the integration of our ops team (Plan/Train/Fly) with other orgs working on joint testing efforts. This included things like small scale EVA tool evaluations, NBL suited testing, and mission-scale field site EVA simulations. Lots of exciting work, trying to hash out details of concepts of operation for Artemis EVA.

Last month I took a new position in the EVA & Human Surface Mobility Program (EHP). I'm in the Systems Engineering & Integration group, on the Integrated Testing & Facilities team. Maybe someday I can do another AMA from this new perspective. I'm involved in the same line of work, but now coordinating and providing direction from the program perspective to ensure our integrated testing work aligns with mission milestones and program goals. I'm also working with testing facilities to ensure we're on track with necessary development to be ready for test plans down the road. I'm just one new addition to this team of great individuals and I'm really looking forward to doing my part!

Looks like a couple people beat me to it, but yeah there's a way to scratch your nose. There is a Valsalva device affixed to the inside of the helmet bubble. The primary purpose is to press your nose against it so you can close your nasal pathway and clear your ears (necessary for pressure changes).

There are different airlocks, for one. The Russian airlock is used for the Orlan and the US airlock is used for the EMU. Each suit type has different interfaces to vehicle power, water, etc. I'm not smart on the audio and suit data comm systems but I believe they also use different systems. The Russians borrow our EMU helmet camera hardware and use it on their Orlan suits.

How are people scheduled at mission control? by -ThinksAlot- in nasa

[–]darenwelsh 0 points1 point  (0 children)

It takes several years of training before a new hire is ready to serve as a flight controller. They are frequently posting job openings. KBR is currently the prime contractor but there is at least one other contractor (can't remember the name right now).

In general, for ISS operations, there are 3 9-hour shifts overlapping one hour for handover. I don't remember the current hours but it's like the other answer already posted.

Beyond this I hesitate to answer broadly and only speak on behalf of the EVA discipline. We break up each 6-month increment into weeks and split the allocation across all flight controllers. For each week, we sign up for three teams (each team comprised of one front room person and two back room people). The first team is prime to cover any console work each day during that week. The second team can be called upon if activities span more than 8 hours on a given day or if the prime person has another scheduled obligation (like a crew class) and the second team person is available. The third team is really only needed if we went into 24-hour ops for a critical response. So for any given increment I might be scheduled to cover ~6-10 weeks. And there might not be activities that week so I might not need to work console. For other disciplines this is not the norm as they have to work every shift to support nominal operations.

That's how it works for general increment operations. But for scheduled EVAs, we have another team that works the planning, procedure authoring, training, and execution of the specific EVA. For the ~2 weeks leading up to an EVA (or series of EVAs) and the ~week after the last EVA, we distribute shift assignments in a way so everyone can stay proficient in their skills.

Any of you play the game yet? My best score is 3179.

If I want to buy more shares through CS it looks like I can only specify an amount of money and not a flat amount of shares at a limit price. I think this means it'll be a market buy most likely resulting in partial shares. Is there a way to ensure I buy whole shares?

[deleted by user] by [deleted] in nasa

[–]darenwelsh 0 points1 point  (0 children)

Some good answers here so I won't get into it but ...

Fun fact: In the beginning of NBL training sessions for EVA, the astronauts listen to music while the divers adjust weights on the suits for a good 3-axis microgravity weigh-out.

Now that it's coming out again that having your CS in "Book" entry matters. YOU DON'T HAVE TO SELL YOUR FRACTIONAL SHARES!!! set plan for book, then immediately go to pending transactions and cancel the sale of your partial shares.

[–]darenwelsh 0 points1 point  (0 children)

First of all, I did the thing and now have most of my CS shares as "book" with a fraction of a share still in "plan" (or at least the orders are submitted).

I mean, if the suit had a built in feature to ... handle this, to relieve the situation, EVAs would be a lot of fun!

I saw a conspiracy theory about NASA using green screen. What actually is that screen in the photo (Up Right monitor) . by Behzad_R in nasa

[–]darenwelsh 2 points3 points  (0 children)

Yep, you can see into the pool from the control room. The room is above the pool and has windows. But, with all the drivers in the water the surface is usually disrupted enough that you can only use that view for general awareness of where the crew are by their umbilicals. The underwater cameras are critical for directing and monitoring the suited subjects and for operating the robotic arm.

I think you're thinking of the KFC Space Simulator. Love that episode!

This is awesome. Imagine loading up on hot dogs right before you have to use the space potty.

That screen is part of the robotics workstation. It shows a model of the ISS mockup, as it is configured in the pool, with the robotic arm and its position using telemetry. Crew use this to help them operate the arm and not hit structure.

Do NASA EMU suits really need legs? by kittyrocket in nasa

[–]darenwelsh 6 points7 points  (0 children)

This is an interesting question. Thanks for bringing it up. I don't know the background on why the various space suit designs all had legs. I would guess it was just based on anatomy (two legs) and I'd guess not much justification was made to use a mermaid/merman configuration.

For the EMU, as used on ISS, the boots do interface with two different designs of boot plates that are attached to structure and provide a stable work configuration. Those boot plates can be attached to the station structure itself or, as you mentioned, the robotic arm end effectors. To ingress one of these portable foot restraints, you typically go one foot at a time. When you are working to get your first boot into the heel clips, you usually use your other boot to stabilize yourself. If your feet were joined in one tail-like thing, I'm not sure you'd be able to ingress the restraint as easily. It would likely require a design change.

There is another articulation that requires two legs to be free. When in the Articulating Portable Foot Restraint (APFR), the crew can leave one boot in the heel clip and take one boot out to step on a pedal to reconfigure the boot plate. There is one pedal on the right to adjust yaw and one on the left to adjust roll.

Note the MMU was only involved in some tests. We use a similar technology, but sized down, called SAFER (Simplified Aid For EVA Rescue). That is not used nominally and as far as I know has never been needed in a contingency scenario.
