I've found plenty of information about the problems of high gravity maneuvering (3Gs+) on humans, but almost nothing about extended exposure (weeks, months) to...

Would it be possible to set up a circular, polar orbit around Mercury such that it always followed Mercury's terminator? Also, could such a "dawn tracking...

sorry if this is a repeat post... How hot would a nearly ideal black body object get in Mercury orbit? I've read that Mercury's daytime temperatures can...

For a big terrestrial planet** with the following attributes: 1) One bar surface pressure 2) Twice Earth's diameter (x4 Earth's area) 3) 1.5G surface gravity...

If Earth had the rather bad run of luck to be removed from the Sun's presence for at least the next few centuries, what would be it's cooling rate over time...

With the recent close conjunction of Mars, is it my imagination, or if I squint, I can *just* make out a visible disc rather than just a point? Matt

Hello, I have to write a high-school level project summarising radio galaxies. The two main classifications of radio galaxies that I have come across are FR...

They are to reformat the flash memory. Does the flash file system have a defect mapping scheme?

I'm intrigued as to why there are no references to the above in any of the 'space' newsgroups. Do you guys know something that the public doesn't? It seemed...

How does low-temp space conditions affect HDPE components?

Even though everything we can detect was apparently a product of the Big Bang, and exhibits red shift, isn't it rather parochial to presume that "everything...

Hello all, I recently watched a show on Discovery about supermassive black holes. Black holes have always fascinated me and this show what also very...

So I want to terraform the moon. As one of the major steps is to deposit a very large number of cubic kilometres of water on it to act as a thermal buffer, I...

I have heard every 19 years (235 lunar months) the moon and the solar year are synchronised. However, after looking at the times for new moons in the almanacs,...
