IOW, no geosynchronous satellites, no manned travel, no extra-planetary. How many "developing" nations could (or would) afford their own LEO satellites instead of leasing space on the already-overbuilt existing satellite networks? |

The whole idea is that they don't need a satellite. The experiments go up in Dream Chaser. It orbits for a while, as work gets done. And then it comes back, bringing both the results and the experimental equipment home again. |

| Good point. LEO satellites aren't the only task a shuttle can accomplish. Long-term scientific experiments can take place on the ISS -- not on a shuttle -- Will the Dream Chaser be authorized to supply the ISS? - Wikipedia wrote:
- The Dream Chaser is designed to resupply the International Space Station with both pressurized and unpressurized cargo.
Yes, I guess it will. Nevertheless, private-but-still-outrageously-expensive access to the ISS will hardly "transform humanity's access to space." |

| The Dream Chaser is pursuing the same market as Elon Musk's SpaceX.
According to the book I just read, NASA used to bill something like $600 million to place a satellite in orbit. The Russian space agency will do it for $300 million. SpaceX aims to do it for a little over $20 million.
What will Dream Chaser charge? |

| Dream Chaser isn't about putting satellites into orbit. And the dream part isn't about supplying the ISS either. |

| The Dream Chaser showed up in the deleted scenes of "The Martian." It was credited as such. |
