A space capsule carrying the ashes of 166 people, along with a collection of cannabis seeds, was lost after crashing into the Pacific Ocean during reentry. The capsule, part of a mission called “Mission Possible” by German aerospace start-up The Exploration Company (TEC), launched on June 23, 2025. Its cargo, arranged through Texas-based space burial firm Celestis, successfully completed two orbits around Earth before communication was lost. While the mission aimed to be Celestis’s first to return from orbit, a reentry anomaly led to the capsule’s destruction and the scattering of its contents at sea.

Space burial mission ends in loss after promising start

The Nyx capsule, designed and launched by The Exploration Company, initially performed well. It powered its payloads in orbit, stabilized after launch separation, and briefly re-established communication during reentry. However, the company lost contact just minutes before splashdown. TEC confirmed the capsule crashed into the Pacific Ocean, with no materials recovered. This was Celestis’s first attempt at a return-from-orbit space burial, carrying remains of 166 individuals entrusted by families around the world. The mission also carried cannabis seeds as part of the Martian Grow project, a citizen science initiative aimed at exploring the potential of farming cannabis on Mars. TEC has only launched one other capsule prior to Nyx, and while they hailed several technical milestones, they acknowledged the risks involved and expressed a commitment to relaunching in the future.

Families mourn while celestis promises support

Celestis co-founder Charles M. Chafer expressed disappointment and offered condolences to the families involved. He acknowledged the bravery of those who chose to participate in a first-of-its-kind return mission and emphasized the symbolic value of having their loved ones orbit Earth before their final resting place in the Pacific Ocean. Despite the tragic outcome, he noted that many milestones — launch, orbit, and controlled reentry — had been achieved. The company has reached out to affected families to offer support and discuss possible next steps. In his words, while no technical feat can replace the personal meaning behind such missions, “we remain committed to serving with transparency, compassion, and care.”
