Impulse Space's Series D round grows to $808 million as backlog expands

By Akash Sriram Sept 16 (Reuters) - Impulse Space has raised $308 million in an extension of the Series D funding round, the startup building spacecraft ‌to move satellites and other payloads said on Wednesday, as it ‌looks to serve a backlog from commercial and government customers. The extension valued the company at $5.6 billion, according ​to a source close to the company. SpaceX's $86 billion IPO in June has bolstered investor enthusiasm for the space sector, helping improve the fundraising environment for companies such as Impulse. The extension brings Impulse's Series D financing to $808 million, following a $500 million ‌round announced in June that ⁠valued the company at $4.26 billion.
