$500 million in new Series D funding values Impulse Space at $4.26 billion, lifting the orbital-transfer startup's total capital raised to more than $1 billion.
Investor demand is centering on space infrastructure beyond launch rockets, as cheaper launches and faster satellite deployment increase demand for vehicles that reposition spacecraft, service satellites and carry payloads deeper into space.

SpaceX's IPO filing last month has sharpened interest in startups founded by former SpaceX executives, benefiting Impulse, which was founded by SpaceX first employee and former propulsion chief Tom Mueller.
