(either way, put the receiving end at the Zenith or Nadir points to keep mishaps at a safe distance from habitats and planets)
A few AU are not a safe distance in astronomic terms, especially if correction of the aim of that matter stream is measured in decades.  :P

While browsing one of my favorite websites, I found this:

http://www.projectrho.com/public_html/rocket/realdesigns.php#mbc

While the proposal does seem like a political stunt by one contractor to get back at a rival, it looks to me like one of the better and more realistic designs for a manned mission to Mars.  The fact the missions it would be best for are more than just flag-planting excursions makes it even better.

Too bad it has an achilles-heel in requiring the SLS for set up.

Project Rho does a remarkable job of keeping up with the times.  The techincal discussion of "The Martian" on that page is particularly worth reading.

Postcards From Somewhere

http://www.cnn.com/2017/10/27/us/mystery-object-solar-system-trnd/index.html

A quarter-mile wide rock busting way past solar escape velocity on a close pass around the sun and Earth, and then out on its way to Pegasus.  Speedwise, it's doing better than 25km/s - which is a good 25% faster than solar escape velocity at Mercury's orbit!  Plus, considering the extreme angle it came in at, basically "up" from the plane of the ecliptic, yeah...it's definitely a foreign visitor.

See you around, little dude, may you reach your destination someday!

Well with the detection capabilities we have now days I think we'd notice it, but seeing as space is so big, I honestly doubt that it don't happen that often, so this could be quite rare.

Too bad we didn't detect it a few years ago, I'd have been willing to chip in a bit extra to get a probe to that!

High-inclination orbits aren't unusual for comets. Probably the best-known long-period - i.e. returning - comet with that kind of inclination is Hale-Bopp at 89.4°.

If you look over lists of near-parabolic comets you'll find that they're basically all over the full angle of inclination, and that there's somewhere around a dozen for the last 20 years that come in from around 90° ("up").

I went with Mjolnir as name.  I rather have something sizable, but hey. I like have a rock named after a Lyran Battlecruiser.  ;)

I submitted the names Outland and Bloom County for my ideas for names.  I like Outland since it pretty darn far out as you can get in Sol.  ;D

For those Kerbal fans, a real life spaceship making an orbital correction burn radially inward. And the amazing thing is that now we have a big cohort of people who know *this is perfectly fine*. Cool, eh?

To be fair they're also using quite some artistic license in depicting that AVUM.

This is true, but it is also a good representation of the spacecraft's attitude during the burn.

What do you guys think of the Russian's upcoming spacecraft, Federation?

It looks like they are using the Dragon Space Capsule as basis for the design. The Russians have begun to select crews for the first flight for the ship.   Spaceflightinsider.com article details about the crew selection.

I didn't know that the Russian ship was that far along. It was announced in 2016.

The design was directly lifted off the previous joint Roskosmos/ESA design for CSTS and predates Dragon by about 5 years.

The crew selection if for first flight in 2023, by which time the spacecraft will have been under development in Russia for about fifteen years and previously together with ESA for about five years - ESA bowed out of CSTS in 2008 still in initial study phase and decided to if at all develop ATV into a manned craft instead.

Was pretty much scrapped, then merged with NASA's Orion - half of which is basically just a ATV after all.

Since a while DC4EU is instead in its pilot phase, i.e. a study to transplant SNC's DreamChaser spaceplane to Ariane 6 for manned European launches.

Dream Chaser at least getting a chance to fly with the cargo missions selected for them.
Looks like ESA gave up on anything manned flight again.

United Nation's space program selected Dream Chaser, but their final decision was suppose to have been made by November 1st.  I try follow the space programs closely and i didn't see any announcements.
