cosmobloom thin-film solar paddles

This project focuses on deployable solar-power enabling technology.


cosmobloom is developing thin-film solar paddles for high-power spacecraft, explicitly including space data centers. Its August 2026 seed announcement targets orbital paddle demonstrations around 2031 and describes membrane-materials and manufacturing research with Taiyo Kogyo. No named computing mission, electrical output or completed orbital demonstration is established.

NEXT MILESTONE

Advance the thin-film paddle design toward an orbital demonstration targeted around 2031.

Manual review 2 Nov 2026. Compared the issuer funding release, current company description and Taiyo membrane collaboration. Retained solar-paddle research and the approximate 2031 target, corporate financing and investor identities without assigning mission hardware or an orbital computing power rating. Primary body last observed not available. Source monitoring: unavailable. Source collection and substantive profile review are separate checks. Plans and dates may change.

WHAT REMAINS UNKNOWN
  • Paddle model, installed power, conversion efficiency, area, mass, dimensions and thermal limits are undisclosed.
  • No named host, computing mission, launch commitment or completed paddle demonstration is established.
  • JPY330 million is corporate seed financing covering multiple development activities, not a paddle-specific or orbital-compute allocation.
  • LEAF deorbit-device figures and the separate long-term power-to-Earth vision are not paddle specifications.
