Also his 36 Hours in Philadelphia was hysterical www.phillymag.com/2013/01/09/3...

This is tremendously sad. Dan was a good man.

My job for the next 48 hours is to rest up and work as little as possible. Almost crunch time.

Going on-console 8pm Thursday for what could be the final 2 prep events prior to Artemis II launch. First, we’ll be following along with a final spacecraft recovery training exercise happening off the coast of San Diego before switching to a launch rehearsal at 11pm at KSC.

Amazing landing by the pilot.

Time’s gettin short.

I know. They can say what they want to say. The reality will be that Artemis II was pulled off by thousands of hard working people, many of them just wanting to be part of something greater than themselves and who love what they do.

I absolutely love them. It’s amazing to walk out there with them and they’re very comfortable with that. Just no fear of us working here. It’s magical.

Our furry team member seems a little annoyed at all the last minute schedule gyrations.

They could make it a reality show! Winner gets to be OC for the week. 16 person bracket. We’d know the OC for the playoffs by week 15.

I think she wanted to have a word with me about all this travel and the resultant lack of walks.

For the first time in a year and a half, I’m waking up without having to work on a major presentation, report, or milestone review. Yeah, there’s a significant review left, but that’s above my pay grade. Only thing left for me is to focus on the mission.

I’m happy to work Artemis II for no pay if it means ICE isn’t being funded.

Added a bit on Orion fire response to the megathread.

Wouldn’t have done a lot of good to put out a fire only to have the crew not be able to;e to pilot the spacecraft back home. The test was productive and we had to make a minor design tweak.

When we got to the final review, we realized we never went back and made sure the control console would still function if someone aimed the fire extinguisher right at it. Just something that got overlooked given the piecemeal development approach.

Well, lithium ion battery fires burn so hot that we needed the phase change from water to steam to dissipate the heat from a fire and be able to control it. So our fire extinguisher is purely water based, not foam or CO2 like ISS or halon like Shuttle.

We have no nominal connections to our O2 system. The only time the crew will ever connect to the O2 system is for a medical emergency. Fan motors are encased in ceramic cans. That led us back to lithium ion batteries which carry all 3 legs of the fire triangle in them.

We looked at other fire sources - avionics/electrical fires, fan motor fires, and O2 fires - but we determined those to be less likely. We flow N2 over our avionics bays; that and the materials make fires less likely to propagate. Connecting to an O2 system always carries risk of ignition, but…

A year or so before I took over as cockpit integration lead, we picked a lithium-ion battery fire as our design to fire scenario. We knew we’d be carrying plenty of electronics and at the time it was assumed we’d have some robust laptops, similar to what ISS uses.

The original requirements for our displays had them only be able to withstand incidental contact with water - drops from a spilled drink, some sea spray through the open hatch. When those requirements were written, we hadn’t defined our fire response equipment.

Another test campaign I sponsored - spraying water at our displays, shown here with our Program Manager Howard Hu at the controls.

Thank you! Can’t wait to see them.

Well, hoping this is the last time I see Artemis II on the pad.

For the record, I’d move back to Philadelphia in a heartbeat if I could send astronauts to the Moon from there.

Bald Eagle flew over me on the drive into our Artemis II readiness review. Go Birds. Gonna go well today.

When you say last call for Flight Readiness chart inputs

Packed an appropriate tie for Friday’s Moon-to-Mars Artemis II Flight Readiness Review.

Their helmet rings could get caught on the console and seat, so we learned they had to shimmy out sideways. Whole team was glad to learn this since we then knew we wouldn’t need to worry about suspension trauma from staying in the seat too long. It was a good test.

We tested multiple different angles including one with the crew member’s head down & body tilted forward about 30 degrees. We had a bunch of different astronauts give it a try & they were all successful. Smaller crew members had a little harder time because their seats are closer to the console.
