PlanValue 3.0Jan 10, 2026RT by @Cosmic_Penguin: RT by @Cosmic_Penguin: Spent the day at Goddard Space Flight Center as the first stop on my roadshow across NASA’s centers. I’m not visiting for photo ops or VIP tours, but to get out where the action is and talk directly with the workforce, the industry partners and congressional delegations. There’s no question there is real work to do across all of our centers, and Goddard is no exception. We carry dated, and in some cases, unsafe infrastructure on our books, along with programs that are not always aligned with our most pressing objectives. We can do better by listening to and empowering the best and brightest to work the problems and pursue the opportunities with u
