  • Tool: Infinite Orbit’s Endurance Docking Vehicle; launch in 2027.
  • Services: Station keeping, pointing management, orbital relocation, end-of-life disposal.

• SES & Relativity Space Launch Agreement

  • Multi-year, multi-launch deal for SES satellites on Relativity’s Terran R, targeting late 2026 first launch from Cape Canaveral.

• GHGSat & SFL Missions (Canada)

  • SFL Missions to build two new microsatellites (GHGSat C18, C19) for greenhouse gas monitoring. Launch set for Vandenberg AFB via SpaceX.

Featured Interview – Dr. Saralyn Mark

Part 1: Career Path & NASA Experience
Timestamps: 09:33–12:22

• Childhood ambitions:

  “I always wanted to be a doctor who practiced on the moon…before I realized that women were actually not allowed in the space program.” [09:52, Dr. Saralyn Mark]

• NASA Tenure:

  • 18 years as senior medical advisor, Office of the Chief Health Medical Officer.
  • Led decadal reviews on sex/gender impacts on space adaptation.
  • Emphasized human factors and health for all 17,000+ NASA employees, not just astronauts.
  • Managed public health challenges during pandemics/outbreaks.
  • Bridged work across NASA, the US Department of Health & Human Services, and served as a civilian advisor.

Part 2: Current Projects & Excitement
Timestamps: 12:22–14:29

• Bioethics in Space Medicine:

  • Launching a 7-part virtual roundtable on bioethics as commercial space expands.
  • Aim: Gather experts to tackle unexplored ethical/policy questions to influence future space mission protocols.

• Public Engagement & Inclusion:

  • Developing “Space Explorer Summits” and interactive workshops, especially targeting underserved communities.
  • Goal:

    “I want to ensure that the next generation also has that same passion [for space]…space belongs to everyone.” [13:33, Dr. Saralyn Mark]

  • Concern: Commercial space could further disenfranchise those without access or representation.

Part 3: Technology Transfer & Public Ownership
Timestamps: 14:44–15:24

• Highlight: Dual-use technologies transfer from the space program benefit everyday health (e.g., Hubble-derived breast imaging in MRIs).
• Dr. Mark’s Call:

  “The public is investing in the space program...It belongs to them.” [15:11–15:24, Dr. Saralyn Mark]

Part 4: Future of Human Exploration & Challenges
Timestamps: 15:24–18:50

• The Imagination Barrier:

  • “We’re limited by our imagination...because we operate in three dimensions.” [15:38, Dr. Saralyn Mark]

  • True deep space missions will require bold leaps in radiation shielding, muscle/bone health solutions, and possibly new pharmaceuticals.

• Risk & Human Spirit

  • Using disaster-movie analogies (“Armageddon”) to discuss calculated risk in space exploration:

    “If you ask a lot of astronauts, would you be willing to go to Mars and experience significant radiation load … you probably would get folks raising their hands…It goes back to the nature of humanity.” [17:44, Dr. Saralyn Mark]

  • Space exploration may build Earth stewardship and appreciation.

Notable Quotes & Memorable Moments

• On Early Aspirations:

  “I always wanted to be a doctor who practiced on the moon...before I realized that women were actually not allowed in the space program.”
  — Dr. Saralyn Mark [09:52]

• On Space and Public Health:

  "When people think of NASA, they think of the astronaut corps...but there's over 17,000 employees that keep that agency running."
  — Dr. Saralyn Mark [11:15]

• On Bioethics & Commercial Expansion:

  “A lot of the questions we’re asking regarding ethics and bioethics, they haven’t been answered. So we're going to bring together leading experts...to begin to ask the questions and hopefully answer them.”
  — Dr. Saralyn Mark [12:49]

• On Technology Transfer:

  “Some of the technology from the Hubble telescope, we've actually utilized it for breast imaging in our MRI devices. It's incredible.”
  — Dr. Saralyn Mark [14:47]

• On Future Challenges:

  "If you're out there and you're not protected by your Van Allen belts and the vehicle that you're in, this could be a really big challenge."
  — Dr. Saralyn Mark [16:31]
