What do you call the bracket that holds and orients your SPT Hall-effect thrusters?
DSM. It stands for DAPM-Actuated SPT Module. And DAPM stands for Dual-Positioning Mechanism. And SPT stands for Stationary Plasma Thruster. Simple.#PI_Daily @MissionToPsyche pic.twitter.com/KCujx07p55

It's @MissionToPsyche Super Tuesday! Lots of high-level reports, and also decisions. Ex:
– Shall we fund from reserves some additional hardware review
– Should we decide now to make our fall all-team meeting 100% virtual
– And about 30 others…#LaunchMinusOneYr#PI_Daily pic.twitter.com/fzxTqDFaLX— Lindy Elkins-Tanton (@ltelkins) August 3, 2021

Question for the ages: How deeply, in how much detail, do you need to verify what someone else tells you abt their work? 2 questions? 10? A panel of questioners? Watching them do it? Redoing it yourself?

Seemingly unrelated jobs today…
– Launch MSRR. Ever think abt how launch vehicle releases s/c w no angular momentum in any axis?
– Organizing papers about mission for pre-launch
– Awaiting NASA HQ’s budget deliberations (they’ve got the really hard work now) pic.twitter.com/CWfeLuWwaW— Lindy Elkins-Tanton (@ltelkins) August 25, 2020
Tomorrow and next day is very exciting Mission Systems Requirements Review (MSRR) for the LAUNCH!

And Proj. Mgt. 1:1. [In which we re-discover that we have similar mgt styles, ethics, and priorities, and feel thankful.]
— Lindy Elkins-Tanton (@ltelkins) August 19, 2020
What we’re working on:
How can we reduce budget to offset COVID costs?
How do we get subs to deliver a better product? On better schedule?Plus, let’s write all our pre-flight science & instrument papers!

Moving fast on @MissionToPsyche. Hard decisions being made.
When good is good enough: Spend $ & schedule time that we cannot afford on an instrument engineering change, to mitigate a risk 7 yrs. out. Getting to launch vs. improving science in the end.
Space is hard!
— Lindy Elkins-Tanton (@ltelkins) July 8, 2020
#PI_Daily Yes, building spacecraft continues!
Today I reviewed Test-as-You-Fly exceptions. Best practice: test hardware exactly as it will be used in flight. Not always possible. For ex: test 24.76-m solar arrays extended in a vacuum! So, strict process for exception approvals. pic.twitter.com/L0OHAfeaO5

A funny day…
Many @MissionToPsyche emails abt meetings for final decisions abt this or that engineering detail (where “detail” is something we cannot move past til final decision made).
Plus a weird bit of PI-ness…checking bona fides on ppl asking unusual Qs.

Sometimes work is pretty prosaic: Working on getting all our published papers into the correct federal database.
And sometimes urgent: Being Bad Cop with a slow vendor.
And sometimes poetic: Dreaming of what Psyche might look like, so @peter_rubin can make new art.

Today is @missiontopsyche MMR (Monthly Management Review).
Two ex. issues:

Today: steep gradient into new COVID-19 world.
All parts of @NASAPsyche now work- or shelter-at-home, or a few exempt ppl at work: @ASU, @NASAJPL, @LockheedMartin, other subs.
I’m so proud of the team. We’ll do our best.
Stay safe and well, friends.#PI_Daily

A number of the missions, @NASAPsyche included, are running reviews this spring. Here is a collection of suggestions for running more effective remote reviews. Many thanks to @AlanStern and @colkin for contributing ideas!#PI_Dailyhttps://t.co/WdA5wgMiqt
— Lindy Elkins-Tanton (@ltelkins) March 15, 2020
Yesterday was discussions abt how to run @NASAPsyche w coronavirus threats.
How many people can’t work remotely (i.e. making hardware)?
Can we run reviews remotely, or will important issues be overlooked by reviewers w/o the in-person immediacy? Anyone have tips?#PI_Daily pic.twitter.com/8bjGy6QGwH
— Lindy Elkins-Tanton (@ltelkins) March 13, 2020
Change Control Board for @NASAPsyche this AM, on magnetometer mass and schedule of s/c assembly.
Then 2 hrs with @SpaceX to plan the path from now until launch! trajectories, coupled loads, tuning ISP…
Now, 1/2 day offsite w @II_ASU & Psyche ASU staff for strategy.#PI_Daily
— Lindy Elkins-Tanton (@ltelkins) March 11, 2020
Mostly, figuring out how to maximize the effectiveness of Webexed reviews, and how to best conduct the business of the mission with travel and meeting restrictions. #PI_Daily
— Lindy Elkins-Tanton (@ltelkins) March 11, 2020
Pretty quiet @NASAPsyche #PI_Daily.
Met w ASU team for mutual updates. Plans for articles, events, Twitter. Updates on budget. Asked for big pile of swag to take to @SpaceX.
Reviewed paper drafts.

#PI_Daily Today is @NASAPsyche Thermal Subsystem CDR. It’s complex to keep all the parts of the s/c at their preferred temp – radiators remove heat, heaters add it, lots of models of how heat will conducted. Google space-rated heat pipe!
