Space Calendar

What Space Calendar does

Space Calendar is the digital publication of Space Age Publishing Company, a privately held US firm founded in 1976 and headquartered across California and Hawai'i. The company's primary product is spacecalendar.com, a weekly space events calendar and editorial publication covering global space missions, launches, astronomical events, NASA and commercial space activity, and space industry conferences. Its business is built on a continuously maintained database of space-related events across multiple venues and organizers, with editorial publications (Space Calendar Weekly) issued under a subscription newsletter model.

The platform's technology stack is a content-oriented web property with calendar integrations for Google Calendar, iCalendar, Outlook 365, and Outlook Live, allowing users to export or subscribe to event streams; no API, SDK, mobile app, or AI features are present. Adjacent products include Downrange 2026 (a specialized launch-tracking interface organized by date, venue, and organizing entity), an Archives section of historical content, and the lunar broadcasting service branded as Moon Message. Moon Message allows individuals and organizations to pay a one-time fee to have text, images, audio, or video transmitted to and stored on the lunar surface via the International Lunar Observatory Association's ILO-1 payload.

The revenue model combines a recurring subscription stream (Space Calendar Weekly newsletter) with a one-time transactional stream (lunar broadcasting reservations). The Moon Message offering is operationally contingent on a chain of counterparties—ILOA for the ILO-1 mission and Venturi Astrolab as the lunar rover service provider—and on the successful execution of those upstream contracts. The customer base is fragmented across space enthusiasts, hobbyists, lunar message contributors, and space industry professionals, with no named enterprise customers, no disclosed management team, no institutional funding, and no disclosed revenue or headcount figures in the source material.

Partnerships

Two partnerships are on record, tiered core.

• International Lunar Observatory Association (ILOA)coreStrategic or Co-development PartnerSpace Age Publishing Company has a separate agreement with the International Lunar Observatory Association for the ILO-1 lunar mission. ILOA is under contract with a lunar rover service provider for the ILO-1 mission, and Space Age's lunar broadcasting services are dependent upon and subordinate to the successful execution of contractual obligations between ILOA and the launch service provider. Content is transmitted to ILO-1 on the lunar surface.
• Venturi AstrolabcoreImplementation/ SI/ Consulting PartnerSpace Age's lunar broadcasting services are dependent on Venturi Astrolab's lunar rover services for the ILO-1 mission. The mission involves multiple third-party entities including Venturi Astrolab and its contract launch provider, all working toward mission success.

Direct peers

• Space.com: Major consumer space-news media site covering launches, missions, and astronomy for a general audience. Direct peer because it competes for the same space-enthusiast readership with daily editorial coverage of the same global space events that Space Calendar aggregates.
• Spaceflight Now: Launch-focused space news site with detailed mission coverage and schedules. Peer because its core product — structured launch and mission reporting — directly overlaps with Space Calendar's 'Downrange' launch-tracking sub-product.
• collectSPACE: Niche space-history and memorabilia news site covering missions, artifacts, and collector events. Peer because it serves a comparable niche-audience space community with editorial coverage of missions, events, and commemorative content — adjacent to Space Calendar's lunar-commemoration positioning.
• Universe Today: Long-running space and astronomy blog/podcast aimed at enthusiasts. Direct peer because it targets the same hobbyist audience with mission news, launch coverage, and event-style content that overlaps with Space Calendar's calendar-plus-editorial model.
• NASA Watch: Long-running space-policy and industry news site covering NASA, commercial space, and launch schedules. Peer because it reports on the same space-industry events, conferences, and mission milestones that Space Calendar lists, targeting an overlapping professional/enthusiast readership.
• Astronomy Magazine: Consumer astronomy publication covering sky events, observing guides, and space missions. Peer because it overlaps with Space Calendar's astronomy-event listings and enthusiast readership, providing calendar and editorial coverage of celestial events.
• SpaceNews: Industry-focused space news publication covering commercial, civil, and military space. Peer because it serves the same professional/space-industry segment that Space Calendar's events listings and weekly newsletter address, with overlapping coverage of launches and conferences.
• Sky & Telescope: Astronomy magazine and events calendar covering sky events, conferences, and observations. Peer because its audience (amateur astronomers and skywatchers) and content type (event listings, observation guides) overlap materially with Space Calendar's astronomy-event coverage.

Broad incumbents

• Ars Technica (space section): General technology publication with a dedicated space and science section covering launches and missions. Broad incumbent because it publishes overlapping space editorial to a larger tech-literate audience, though space is one vertical inside a much broader publication.

Emerging players

• The Planetary Society: Space-advocacy nonprofit publishing mission news, policy updates, and event programming. Peer because it publishes space-related editorial and event content to a comparable enthusiast base, though its funding model (membership/donations) and advocacy mission differentiate it from Space Calendar's commercial publishing model.
