Hi! My Fist New topic!
I didn't know if the category is right. I finally chosen private missions thinking in its potencial for private use
Mr Moderator, if you think this goes anywhere else feel free to move it (I know you don't need my authorization, I'm just being polite)

It was strange to me not to hear anything about this in UMSF. ( Maybe I missed it?). As one of the articles say, taking this
approach can change drastically how missions can be designed.

Sending a lot of fuel in one big tank, for instance, is far more weight efficient (cheaper) than sending along with your ship.

And if you are going to stay in earth orbit, you can design your craft with smaller tanks and relly on resuplys

Thanks for posting about this. The idea has been around for years in the U.S. commercial area, but no one has ever done anything about it that I'm aware of. I had no idea that DARPA was doing this, so I'm checking the web sites you showed.

Here You can follow the news and watch a video of ASTRO placing a battery on its client satellite.
