Episode Overview

This episode of 13 Minutes Presents: Artemis II tracks Artemis II as it approaches its dramatic lunar flyby—the crew is set to loop around the far side of the Moon, go further from Earth than any human in history, and break the distance record set by Apollo 13. The hosts provide mission updates, explore lunar mechanics, discuss astronaut psychology and health, and feature a dispatch from Mission Control as anticipation builds for the flyby.

Key Discussion Points & Insights

1. Special Message from Apollo Astronaut Charlie Duke

• Former Apollo 16 astronaut Charlie Duke leaves a heartfelt message for Artemis II.
  • Quote: “Below you on the moon is a photo of my family. I pray it reminds you that we in America and all of the world are cheering you on. Thanks to you and the whole team on the ground for building on our Apollo legacy with Artemis, Godspeed and safe travels home.” — Charlie Duke (02:12)

2. Pre-Flyby Updates: Crew Testing and Trajectory

• Artemis II is now within the Moon’s “sphere of influence,” meaning lunar gravity dominates.
  • Kristin Fisher: “The Artemis crew is now within what’s called the Moon’s sphere of influence...the most exciting and visually stimulating part of this mission” (03:15)
• Crew successfully completed suit pressurization tests in Orion at 11 psi (2/3 of Earth’s atmosphere) to simulate emergency scenarios.
  • Tim Peake: “It becomes very difficult to work when we go on a spacewalk... Your fingers are very stiff. It's hard to bend your arms. Any fidelity goes away from your gloves.” (05:08)
• A “correction burn” was executed, perfecting their trajectory. Previous planned burns had been skipped—their course was so accurate.

3. The Lunar Flyby: Ambitions and History

• The crew will break Apollo 13’s distance record, intentionally this time.
  • Kristin Fisher: “They’re set today to break that record for the furthest that humans have ever gone from Earth. And of course, that record was set by Apollo 13, not on purpose, but out of survival…” (07:01)
• The mission includes a planned 46-minute communications blackout while passing behind the Moon—a tense but expected event Mission Control and crew have trained for.

4. The Moon’s “Far Side” and Observations

• Clarification of “far side” vs. “dark side” of the Moon; discussion of tidal locking.
  • Maggie Aderin: “Tidal locking…is about how the Moon rotates on its axis and orbits the Earth at the same time. So the same side of the moon is always facing towards us.” (08:45)
• The crew will witness the terminator (the line between lunar day and night) and observe lunar terrain, illuminated in unique ways.

5. What the Crew Will See: Human Eyes and the “Private Eclipse”

• The crew will directly observe, sketch, and audio-describe lunar features; human vision brings nuance beyond any camera.
  • Kristin Fisher: “No camera can quite capture all the intricacies like the human eye can.” (10:09)
• Unique “private eclipse”: The precise launch date means only this crew will see the sun’s corona as the Moon passes in front of the sun—a view invisible to anyone else in the solar system.
  • Kristin Fisher: “…Only these four people are going to get to see the sun’s corona peeking out from behind the moon.” (10:51)

6. The Legacy of “Earthrise” and Viewpoints

• There’s anticipation about whether Artemis II can recreate the iconic Apollo 8 “Earthrise” photo.
  • Kristin Fisher: “No pressure, right? Forget about launch and re-entry. I've got to recreate Earthrise...” (13:04)
  • Tim Peake: Cautious expectations about recreating the photo, given their 4,000-mile altitude (13:46).

7. Mission Records: Distance and Trajectory

• Explaining the record distance: Artemis II targets 406,773 km from Earth, surpassing Apollo 13 by 6,600 km.
• Differences in trajectory: Artemis II’s free return trajectory is planned; Apollo 13’s was an emergency.
  • Tim Peake: “Artemis II is a planned free return trajectory, but interestingly, so were most of the Apollo missions...” (15:26)
• The notion of “free return” means, thanks to celestial mechanics, no propulsion is needed after the initial trajectory adjustment.
  • Maggie Aderin: “…it’s sort of free return, so no propulsion needed…Newton's laws all at work.” (18:24, 18:58)
• Clarification: Artemis II will not enter lunar orbit; only future Artemis lander missions will do so.

8. Astronaut Health and Behavior: Interview with Dr. Matthias Bazna

• Why test astronaut cognition?

  • Astronauts must maintain peak performance; even small cognitive lapses can risk the mission.
  • NASA’s specially designed test battery includes risk-taking, emotion recognition, memory, and vigilance.
    • Dr. Matthias Bazna: “Taking an off the shelf test battery that we routinely use on Earth may not really work for astronauts because the test may be too easy for them, it may be boring. It may also not be sensitive enough…” (21:50)

• Sleep and Circadian Rhythms in Space

  • Space disrupts normal human sleep: ISS astronauts only clock just over six hours' sleep—less than the recommended seven.
  • Sleep deprivation, high CO2, and noise can fragment sleep and degrade cognitive performance.
    • Dr. Matthias Bazna: “Astronauts...typically clock a little bit above six hours of sleep. You know, that's the data we have so far. And that is not really enough...” (32:46)
    • “We found that on the ISS the caffeine consumption actually goes up, you know, as the mission progresses...” (32:46)
    • Tim Peake: “You do not want to be on a space station that's running out of caffeine. Caffeine, it's the worst place in the world.” (34:56)

• Long-Duration Flight: What Happens to Astronauts?

  • Findings from the NASA Twins Study: Major cognitive decrements in astronaut Scott Kelly appeared after returning to Earth, not while in space. The brain’s re-adaptation to gravity may be “the bigger problem” than the flight itself.
    • Dr. Matthias Bazna: “The interesting thing with Scott [Kelly] was that we saw more major decrements once he returned to Earth and that was not...something that went away quickly.” (27:17)

• Confinement and Personal Space

  • Unlike the ISS, Artemis II’s Orion capsule is extremely small for four people. For longer missions, lack of private space could increase tension and psychological stress.
    • Dr. Matthias Bazna: “We as humans, psychologically we need our own space. At some point during the day, we need to be on our own…” (30:02)

• Why is Artemis II scientifically important?

  • This mission takes the first modern human crew outside of Earth’s strong magnetic field (“comfortably in low Earth orbit”), exposing them directly to space radiation—crucial for studying its effects.
    • Dr. Matthias Bazna: “There is no turning back...Space radiation is one of the potential showstoppers…” (35:57)

9. Dispatch from Rebecca Morelle, Inside Mission Control

• Scene inside Houston: Teams intensely monitor Artemis II; each flight controller is focused on different spacecraft systems.
• The upcoming 40-minute comms blackout is “incredibly tense”—entirely normal, but emotionally gripping for everyone in Mission Control.
  • Rebecca Morelle: “[T]he link is going to be lost as the Moon blocks the signals from the spacecraft. I mean, it is going to be an incredibly tense time here...” (39:21)
• The real excitement for scientists: Beyond stunning images, it’s the astronauts’ audio descriptions—personal, scientific impressions in real time—that will “really add the context to the images, they'll bring them to life.” (41:13)

Notable Quotes & Moments

• Charlie Duke’s encouragement: “Godspeed and safe travels home.” (02:12)
• Kristin Fisher on the ‘private eclipse’: “Only these four people are going to get to see the sun’s corona peeking out from behind the moon.” (10:51)
• Maggie Aderin on the relevance of school maths: “Sometimes we're doing that sort of that maths in school... you think, what's this all about? This is what it's all about. And it really works.” (20:07)
• Dr. Matthias Bazna on astronaut privacy: “The crew, they need to have their private quarters, however small they're going to be...” (30:02)
• Tim Peake on caffeine: “You do not want to be on a space station that's running out of caffeine.” (34:56)
• Rebecca Morelle on astronaut audio descriptions: “They'll really add the context to the images, they'll bring them to life...we'll also hear the excitement in the astronauts' voices.” (41:13)
