The goal? To share an inside look at the chores, challenges, tasks, assignments, duties, and more taken on by a NASA mission PI!

In the interest of authenticity, I'll share that most of my time on @MissionToPsyche now is working on the Phase E budget & schedule, trying to pull back money & time. It's really important: If we can do with less, then there is more for others. But it is not glamorous. #PI_Daily

We don't think Psyche was likely to have iron-nickel metal volcanism, but we think planetesimal cores in general may have erupted FeS (liquid troilite, with Ni mixed in).

In Talca, Chile, where there was an 8.8 earthquake in 2010. Hereβs a house that was ruined then. Speaking to about 600 people in the opera house, with many other speakers, part of #CongresoFuturo2020. #PI_Daily pic.twitter.com/DL2xJzV8NK

Completed first @NASAPsyche talk at #CongresoFuturo2020. Exploration as inspiration to solve the problems confronting us. Now to Talca to give another talk tomorrow. #PI_Daily

Still polishing up the @NASAPsyche talks for #CongresoFuturo2020 in Santiago & Maule, Chile, this week. Wonderful event and excited to introduce everyone to our mission. But meanwhile, missing all the important meetings and updates back at the ranch! A hard balance. #PI_Daily pic.twitter.com/YbXw2XFu7j

Off on an airplane to give three @NASAPsyche talks! So today, working on talks and sitting on airplanes. #PI_Daily

Today I talked with a @NASAPsyche graduate student about his progress in research, and with the lead of our magnetometer build about progress there.
Tonight: resubmit the revised “What is Psyche?” paper! #PI_Daily

These Monthly Management Reviews are super-helpful deep dives into how each instrument, subsystem, or the whole project is progressing. Technical, schedule, cost…etc. Usefulness depends upon open fearless communication! Always working on that. #PI_Daily (2/2)

Today Project Systems Eng mtg, Risk Board mtg, PM/PI 1:1. We track all identified risks to the mission using 1-5 scale for likelihood & consequence. We go over all top risks, and we look at any new ones. For success & safety conversation has to be open! #PI_Daily @NASAPsyche pic.twitter.com/NsP5xuvtyk

Today’s @NASAPsyche #PI_Daily-4 mtgs: lead engineer, proj scientist, staff mtg, weekly tag-up of NASA HQ, Marshall, JPL, & ASU leadership. Catching up on top risks & challenges. Big topic: cadence of subsystem CDRs up to project CDR. Will we be ready? (Y!) https://t.co/qwoxDjJR88

Jan 6 @NASAPsyche #PI_Daily from the PI…fielding final comments on new paper integrating all current data on Psyche. Discussing possible import of meteorite Steinbach. Phone calls and emails on #LPSC2020, #PI_Daily (!), a staff change due to retirement. Good day.

Three years ago yesterday @NASAPsyche and @NASALucy2Trojan were selected for flight. Those three years surely have moved fast! Now we are under 1,000 days until launch.
And for anyone interested in the effective #PI_Daily of that day, here’s a blog: https://t.co/8rDY2DGnzc?

.@NASAPsyche #PI_Daily for Sun. Jan 5: Spent ~4 hours revising our new team paper, colloquially called “What is Psyche?” What does all the latest data add up to? A super-mysterious asteroid!
Special thanks to our three reviewers for being helpful, substantive, and kind! Whoa!

The more prosaic part of space mission work today: writing recommendation letters for junior members of the team who are applying for new jobs or other internships. When I really know the person and we have actually worked together, I am happy to write. π§β¨οΈπ¨οΈ #PI_Daily

Long computer day. Looking at results of a Psyche occultation (@colkin π) and reading a series of #LPSC2020 abstracts from the Psyche team — submission Jan. 7! Ideas about the collisional history of Psyche, and updates on data analysis for the GRNS, among others. #PI_Daily!

…confirmed scheduling project CDR May 11-15. This is #FestiveCDRseason, 17 CDRs plus the big project CDR. It’s the season of the giving and receiving of pptx decks!
Plus, this is what it looks like outside, second-to-last day before heading back to Arizona. pic.twitter.com/LNzxlNVAFD

Two #PI_Daily posts today! In our important weekly 1:1 Project Manager Henry Stone and I discussed the scheduling and budgeting of our C&DH (command and data handling, the brainstem of the s/c — ahem, spacecraft) build, and …

So far for @NASAPsyche, a 1-hr interview for an article, & two phone calls on mission processes w ppl working on other missions. Later, usual hour-long catch-up between myself & Henry Stone, the Project Manager (top boss) for Psyche at @NASAJPL. One more update later. #PI_Daily

Today, Jan. 1, 2020, for @NASAPsyche I read three reviews for a paper we’ve written abt what the asteroid Psyche might be, and I mentally prepared to make the revisions to the paper over the weekend. #PIDaily

Hello space enthusiasts!
Starting today, several mission Principal Investigators & Deputy PIs will be daily tweeting their everyday tasks, efforts, challenges in working on their missions. Goal is to share the experience! (1/2) ππ°π

My inaugural #PIDaily tweet! Will share PI activities for @NASAPsyche regularly. Watch the hashtag for other PIs and Deputy PIs to share their chores, challenges, tasks, assignments, duties, etc on a near-daily cadence.
