MARS300
Be Among the First Human Memorials on Mars

QUICK ANSWERS

Frequently Asked Questions

• How many participants are accepted for Mars300?

  Mars300 is strictly limited to 300 participants for the inaugural mission.

• What is required for the sample?

  Participants provide a symbolic portion of cremated remains or a preserved DNA sample per the Flight Kit instructions; Celestis prepares capsules following certified lab procedures.

• How do payments and protections work?

  Celestis requires a 10% down payment to secure your spot; the remainder is held in trust and released in milestones tied to mission progress, providing protection and refundability until milestones are met.

• Can I include a pet or multiple participants?

  Mars300 accepts one 1-gram capsule per participant as defined by Celestis. If you want multiple participants or to pair a pet with a loved one, contact us — we’ll confirm current Celestis policy and arrange a tailored quote. (Celestis policies may vary.)

• Are launch events and memorial services included?

  Families are invited to pre-launch memorial services and may access mission webcasts; Celestis typically offers an in-person event and a webcast for remote attendees.

• Does the service create space debris pollution?

  Celestis spacecraft and missions are carefully designed so as not to create space debris, and cremated remains and DNA samples are never released into space. Each Earth Orbit Service spacecraft either stays permanently attached to a rocket stage or a satellite that orbits Earth until the spacecraft harmlessly re-enters and is completely consumed by Earth’s atmosphere — blazing like a shooting star in final tribute to the passengers aboard. For Earth Rise missions the Flight Capsules are flown and recovered, Luna and Voyager missions are flown aboard or as part of a spacecraft and not released. Celestis spacecraft and missions are carefully designed so as not to create space debris, and cremated remains and DNA samples are never released into space. For missions launched aboard a commercially purchased launcher, the Federal Aviation Administration (FAA) Office of Commercial Space Transportation issues a license verifying that the payload does not contribute to orbital debris. For any missions not subject to FAA approval, Celestis voluntarily follows these same strict guidelines to ensure that every mission remains environmentally responsible and prevents orbital pollution.

• Are cremated remains or DNA samples released into space?

  Celestis spacecraft and missions are carefully designed so as not to create space debris, and cremated remains and DNA samples are never released into space. Each Earth Orbit Service spacecraft remains permanently attached to a rocket stage or satellite until it harmlessly re-enters and is consumed by the atmosphere, while Earth Rise missions are flown and recovered. For Luna and Voyager missions, the capsules are flown as part of a spacecraft rather than being released, ensuring the flight samples remain contained throughout the journey.
