### 5/5 — M2020 emeritus still enjoying it!

*2025-05-12*

I don’t work on this specific mission anymore but having the the DOY and UTC on my wrist has been super helpful for other “space time” purposes. And it’s fun to follow along from afar. Thanks for keeping it around!

### 5/5 — Informative

*2021-05-10*

Nice app, but of limited usefulness to those not part of the mission team. If the meetings or information assembled were open to the public and you could link to them from the app, this would be a treasure trove. As it is, it’s mostly a calendar app for the team.

### 5/5 — Great app

*2021-02-20*

This app tells me a lot of info!
Thank u!!!
