Brief overview

Staying on the moon and reaching Mars needs permanent infrastructure and an all-of-us government-industry effort.

  1. Going back to the moon to stayExtended stays need power, food, logistics and habitats — permanent infrastructure, not Apollo-style sorties.
  2. Look for what falls through the cracksHer ISS attitude-control warning came from spotting a gap, elevating it, and then solving it herself.
  3. Manage risk by always having an outGeneric aborts and redundancy cover the failures nobody predicted, because the safest place is still the ground.
Executive Summary AI
  • Host Andres Almeida introduces Nuzhud Miranzi, NASA's Deputy Associate Administrator for the Strategy and Architecture Office within the Exploration Systems Development Mission Directorate, on the APPLE podcast Small Steps, Giant Leaps.0:20
  • She contrasts Apollo, a sortie of no more than three days at the lunar equator, with future missions that must survive two-week equatorial nights and days-long darkness at the South Pole, requiring power systems, food, logistics and habitats built up as permanent infrastructure.1:41
  • Describing systems engineering as balancing power, thermal and vehicle systems (their office mascot is a balloon animal), she recounts writing ISS software that detected loss of attitude control and woke the crew, which later triggered for real years after she left the program.5:03
  • On acceptable risk she argues all spaceflight is inherently dangerous, so the work is keeping an out at every step: generic aborts and redundancy such as three oxygen tanks sized so the crew can come home on two.7:44
  • She closes on scale and culture, noting the moon needs tens of launches and Mars dozens if not hundreds, so multiple providers and government plus industry are needed, and her own giant leap was simply finding her way to JSC the year after college.10:41

“Yeah, it's a great question because, I mean, in the end, all spaceflight is dangerous.”
