A weekslong rally in space-related stocks came to an abrupt halt on Friday, with the explosion of a Blue Origin rocket serving as a glaring reminder of the risks that come with the potential riches investors hope to reap from the blossoming industry.

The Jeff Bezos-backed firm¡¯s New Glenn rocket blew up Thursday evening while undergoing a test on a Florida launchpad, ahead of plans for it to deploy satellites for Amazon¡¯s Leo, a rival network to SpaceX¡¯s Starlink.

The explosion dealt a major setback to Blue Origin¡¯s efforts, and will likely lead to delays. It also raises questions around a platform that was among companies selected just this week by NASA to help jumpstart its lunar base program.
