Karman+

Asteroid-mining startup headquartered in Denver, Colorado (relocated from the Netherlands in 2022) that states it plans to excavate regolith from near-Earth asteroids and extract water for in-orbit refuelling. It has flown no spacecraft; its first mission, a technology demonstration now targeting asteroid 99942 Apophis (Karman+ Mission 1 (High Frontier, Corvus spacecraft)), slipped from early 2027 to a mid-2028 launch according to the company.

Karman+ first mission slips to mid-2028 and retargets to Apophis
Schedule changeKarman+With Karman+ Mission 1 (High Frontier, Corvus spacecraft)
Karman+ said its first mission's early-2027 launch slipped because its propulsion vendor could not deliver on time, that the new launch slot is mid-2028, and that asteroid 99942 Apophis became its target. In October 2025 the company had said it would launch on SpaceX Transporter-19 in about 15 months.
