Just thought I'd list the waypoints the various manmade wanderers will cross in 2008

New Horizons:
3 more centaur orbits (of those that have been named)
Saturn's orbit
midway point between the Sun and Uranus

Messenger:
Over two complete orbits
2 gravitational encounters with Mercury (with photographs!)

Rosetta:
Crossing both Earth and Mars orbits
1st encounter with an asteroid

Dawn:
crosses outside of Mars orbit in preparation for a 2009 encounter

any other craft highlights?

Only that little plodder Phoenix. I guess these days mars is so old hat :-)

OK.

Phoenix:
Lands on Mars (fingers, toes and any other digits crossed as hard as possible)

Target date, 4 August. Something to look forward to.

Isnt it late May? Traffic probs maybe :-)

I was wondering why they had decided to go with a different decent/landing mechanism than that for the MER vehicles.

Anyone know the risk differentials for the two approaches to landing on mars?

Phoenix is landing with the old Mars 2001 lander hardware that was nearly finished before it was canceled after the twin '99 failures.

At the time that Phoenix was selected, there was only the Pathfinder landing that had proven airbags - MER was still some years off.

Got it. Was'nt the Polar Lander one of those which went AWOL? Using same decent and landing mechanism?

I'm sure it will be ok - or thats what my doctor always says :-)

The Rosetta-Steins encounter will occur on 5 September.

Cassini, Venus Express and Mars Reconnaissance Orbiter will all end their primary missions this year.

Moon Mineralogy Mapper - India - launch in March 2008


Some non-wandering spacecraft of interest.


Orbiting Carbon Observatory - launch in mid 2008

Herschel far-infrared space observatory - ESA - launch in July 2008

Five Planned Shuttle launches.

European Automated Transfer Vehicle aka Jules Verne to Space Station - Feb/March 2008

... Herschel far-infrared space observatory - ESA - launch in July 2008 ...
How can you mention Herschel and not mention Planck? Both are going up on the same rocket.

Lots to look forward to. Bring on the Exams. So long as I've Space Exploration, I can make it!

On 3/12/08 Cassini will perform a close flyby of Enceladus at an altitude of 23 km (14 miles).

Hey, if you are going to talk about the progress of spacecraft in 2008, shouldn't you talk about Progress spacecraft (http://en.wikipedia.org/wiki/Progress_spacecraft)in 2008?

Looks like there are four flights scheduled for 2008. LINK (http://www.seds.org/~spider/shuttle/iss-sche.html)

Unintentionally very funny.

Unintentionally very funny.
You don't know me very well.
Intentionally funny, then I edited it to add some real information.
But don't worry, you're making progress.

Okay, that one I got.
