Space Burial Suborbital vs Orbital — Mission Types Explained
The Four Mission Types
Space memorial providers offer different tiers based on how far the ashes travel and whether they return. Each tier uses the same basic process — 1 to 7 grams of cremated remains sealed in a custom flight capsule, launched as a secondary payload on a commercial rocket — but the destination and outcome differ dramatically.
Suborbital ("Earth Rise")
The capsule rides a rocket to the edge of space — roughly 60 to 100 miles altitude — then falls back to Earth. The entire flight lasts about 10 minutes. The capsule is recovered and returned to the family as a keepsake.
What happens to the ashes: They stay sealed inside the capsule the entire time. They briefly experience weightlessness and the view from the boundary of space, then return intact.
Pricing: Starting at $1,495 (Celestis Earth Rise).
Best for: Families who want the symbolism of a space journey but also want the physical remains returned. The recovered capsule becomes a tangible memorial.
Earth Orbit
The capsule is deployed into low Earth orbit (LEO), where it circles the planet alongside satellites and the International Space Station. It stays in orbit for months to years, depending on the mission, before orbital decay pulls it back into the atmosphere, where it burns up on re-entry.
What happens to the ashes: They orbit Earth until atmospheric re-entry destroys the capsule. Nothing is returned.
Pricing: Starting at $4,995 (Celestis Earth Orbit). Beyond Burials offers orbital flights starting around $2,490.
Best for: Families who find meaning in the image of their loved one circling the Earth. Orbital providers offer real-time tracking apps so survivors can look up at the night sky and know the capsule's exact position.
Lunar
The capsule is sent to the Moon's surface as part of a lunar lander mission. The remains are permanently deposited on the Moon.
What happens to the ashes: They stay on the lunar surface indefinitely. There's no retrieval, no re-entry, no degradation. The Moon has no atmosphere or weather to disturb them.
Pricing: Starting at $12,995 (Celestis Luna). This is the most mission-dependent tier — lunar flights happen only when a commercial lander has available payload space, which can mean years between opportunities.
Best for: Families with the budget and patience for a rare, permanent placement. The Moon is visible from Earth, which gives survivors a specific celestial object to look at and associate with the memorial.
A caveat on lunar missions. The Astrobotic Peregrine lander carrying Celestis' Tranquility Flight in early 2024 suffered a fuel leak and never reached the Moon. Celestis guaranteed all participants a free re-flight on a subsequent lunar mission. This is a real risk — verify the re-flight clause in any lunar contract.
Deep Space ("Voyager")
The capsule leaves Earth orbit entirely, entering a permanent heliocentric orbit — circling the Sun alongside the planets.
What happens to the ashes: They travel through interplanetary space indefinitely. No return, no burnup, no landing.
Pricing: Starting at $12,995 (Celestis Voyager). Some deep space flights are priced identically to lunar missions.
Best for: Families drawn to the idea of permanence beyond Earth. Deep space flights carry strong symbolic weight for people who were science enthusiasts, astronomers, or simply wanted to leave Earth permanently.
Side-by-Side Comparison
| Feature | Suborbital | Earth Orbit | Lunar | Deep Space |
|---|---|---|---|---|
| Altitude | 60–100 miles | 100–400+ miles | 238,900 miles | Beyond Earth orbit |
| Duration in space | ~10 minutes | Months to years | Permanent | Permanent |
| Remains returned? | Yes | No (burns up) | No | No |
| Tracking available? | No (too brief) | Yes (orbital apps) | Provider-dependent mission or location records | No (too distant) |
| Starting price | $1,495 | $2,490–$4,995 | $12,995 | $12,995 |
| Mission frequency | Most common | Common | Rare | Rare |
| Launch failure risk | Low (simpler flight) | Moderate | Higher (complex mission) | Higher |
The Re-Flight Guarantee
Launch failures happen in commercial spaceflight. Some providers handle them through re-flight guarantees; if the contract provides one, your ashes (or a backup portion stored terrestrially) may fly again on the next available mission at no additional cost.
Celestis' arrangement reportedly requires families to submit an "extra" portion of remains that the provider keeps in secure storage specifically for this contingency. If the primary launch fails, the backup portion flies on the re-flight. Not every provider offers the same terms. Ask before signing:
- Is the re-flight truly free, or are there administrative fees?
- If the provider ceases operations before the re-flight, what happens to the stored remains and the deposit?
- Is the re-flight on the same mission tier, or could you be downgraded?

How to Choose
The decision comes down to three factors: budget, permanence, and what kind of symbolic meaning the family attaches to the memorial.
If the physical return of the capsule matters, suborbital is the only option. If permanence matters most, lunar or deep space are the choices. If the family wants an active tracking experience — watching the capsule orbit overhead — Earth orbit is the most interactive.
