Yes, blogging can be exhausting. It's work, after all.
*shrug* If that helps, go for it.
Have a good rest. Hope to see you soon.
Have you read Dune by Frank Herbert?
On Larry's e-mail list, someone remarked that humans will remain flatlanders until we embrace nuclear rocketry. What is your opinion?
Chemical rockets demonstrably lack the oomph to open up the solar system. That's why interplanetary missions, even robot missions weighing only a few tons, generally play loop-de-loop with a planet or two: to get acceleration from gravity assist.
Is nuclear rocketry the answer? Perhaps *an* answer, but probably not the only one. Space elevators (cheap delivery of lots of mass to low Earth orbit) plus ion propulsion (cheap, efficient, long-term propulsion) seems like another answer.
