#BlueOrigin will “compete” two solutions

• make the expendable 🗑️ upper stage so cheap 💵 to manufacture that a reusable stage can never compete with it
• make the reusable ♻️ stage so operable that an expendable stage can never compete with it

There is still a lot of room with these heavy lift […]

#BlueOrigin is charging roughly $110 million per launch, compared to about $70 million for a #Falcon9 – effectively offering to carry twice as many satellites for roughly 50% more money https://www.forbes.com/sites/jeremybogaisky/2025/01/11/new-glenn-bezos-blue-origin-musk-spacex/

The reason for 3I’s ☄️ rapid brightening, which far exceeds the brightening rate of most Oort cloud comets, remains unclear. Continued observations 🔭 may help provide a more definitive explanation for the #comet’s behavior https://arxiv.org/html/2510.25035v1
