    I agree. It isn't $40 billion. This was a presentation and maybe the press will pick it up and Bill Nelson is a figurehead that plays to the press. That said, it could get there with development costs and business costs (the billion a year that ULA was getting for launch on demand for many...

    Off Topic: Voyagers

    I can't wait for a Voyager upgrade. These things are amazing and just imagine if we have a modernized version(s) sent out there. I'd like to see a dozen of them sent in many different directions. Maybe with video and pictures that people 50 years from now can get.

    SLS - On the Scent of Inevitable Capitulation

    If I am understanding this correctly, and NASA is only having SLS and Orion take astronauts into LEO then that really makes no sense. You could have F9 and a Dragon take the astronauts to the ISS and transfer them to the HLS Starship there for the Moon. You do the same thing on the way back...

    Dragonfly Mission to Saturn moon Titan

    I wonder if it would be good to have a nuclear thermal "battery" as a back up. You can't recharge them but having that energy available if needed would make sense.

    SpaceX F9 - East Coast Starlink Launches - LC-39A and SLC-40

    If I remember correctly, the original statement on a Starlink satellites operational life was five years. That could easily be adjusted with improvements and real world data. Here is a current breakdown of each operational group and how many are functioning compared to satellites...

    Falcon 9 Reuse Leaders

    I couldn't agree more. Somewhere around 2014 it was said that a Merlin engine cost $1 million each. That was prior to the mass production (in rocket engine terms) that SpaceX is currently doing. Knowing SpaceX and Elon, I would guess that each Merlin is down to $500,000 each or less. SpaceX...

    Mars and Off Planet Colonization - Pros and Cons Discussion

    I'm pretty sure it will happen if Elon has any control over the situation. He already understands that he won't live long enough to see colonization happen but I'm sure he hopes to see his Starship factories pumping out one to two ships a week. I expect he will put someone in charge of SpaceX...

    Moon Landers (Non-SpaceX) - General Discussion

    Is it me, or do all these Moon rovers look stupid. The worst being the IM, Boeing, NG "Moon Racer." The Astrolab one looks the best of the bunch. Strangely, the ones in the video look better than the more official three options. I do like the idea of a vehicle that can work autonomously as...
