Manned Only Please
To be honest, the only quote I care about in this article is:
"While it may be even farther into the future, NASA is also planning to conduct a manned mission to Mars -- work that the space agency says remains on track."
No offense to the author, and no offense to the scientists working hard to build and launch this unmanned vessels, but they aren't moving the needle. They're not exciting the hearts and minds anymore, and they aren't going to save us from the risk of extinction on Earth. Get people on Mars. Then keep going ... until a superior race of beings finds us and destroys us. But let us at least be destroyed on the move.
