SpaceX’s nascent monopoly faces durability test A $1 trillion-plus valuation is only the opening act for SpaceX’s rockets-and-satellites empire. After an IPO, deep-pocketed rivals — notably Amazon — are poised to deploy competing broadband services that could erode Starlink’s pricing power and squeeze SpaceX’s access to capital.

ISRO pins NVS-02 failure on unconnected wiring that caused pyro‑valve signal loss and blocked orbit raise More than a year after launch, ISRO's apex committee concluded a pyro‑valve signal loss — traced to unconnected wiring — caused a valve malfunction that prevented the NVS‑02 navigation satellite from executing its planned orbit‑raising manoeuvres. The finding attributes the programme setback to a hardware/integration error.
