I posted this to the NASAspaceflight forum but it actually belongs to this forum.
the schedule comprises a few events that are not yet approved or fully funded (ExoMars launch, Deep Impact 3rd flyby etc.), I have not yet found a schedule of BepiColombo flybys after the recent one-year delay and I have not looked in detail at ESA's Solar Orbiter or NASA's Solar Probe+

That's a very nice list, very useful. I notice you completely exclude the Moon, and perhaps with good reason since exact dates may be very uncertain. Nevertheless, we can be fairly confident that Chang'E 3 will be sent to land on the Moon in late October 2013. All the other possible flights to the Moon (Luna-Resurs and Luna-Glob, Astrobotic or other GLXP flights, the European lunar lander for the south pole, later Chang'E flights, have uncertain schedules.

Thanks, Paolo, for this summary. I'd add to it that NH Pluto approach observations begin January 2015 (LORRI will first be able to resolve Pluto in, I think, February 2015); the entire data set won't be on Earth until April 2016.

you are right! actually the reason is that the list is adapted from the final volume of my book series on the history of solar system exploration, and so it does not include the Moon...

I have updated the list, it now includes the timeline of the Solar Probe Plus and Solar Orbiter
as usual, I have included only missions that are approved and funded, with some uncertain ones in italics. I have not included lunar missions

Any chance to get a .PDF version, Paolo?

here you go!

I imported the list to Google Docs Spreadsheet (better formatting, also fixed some typos). Needless to say, all credit goes to Paolo.

https://docs.google.com/spreadsheet/ccc?key...ZVFCejhSNHdkQWc (This version is NOT editable. I made a copy of the editable version as a precaution, in case someone deletes the file, or somehow screws it up)

just a quick reminder of what's in store for solar system exploration in 2013:

four launches: LADEE (currently planned for 12 August), Chang'e 3 (second half of 2013, the first attempted lunar soft landing in 37 years!), MAVEN (window opens 18 November) and Mangalyaan (November)
one flyby: Juno flies by Earth on 9 October
one end of mission: MESSENGER in March (I have not yet heard of a further mission extension)

with my best wishes for a lucky 13 to everyone in the forum!

Many thanks for a very useful list! And best wishes to all for what indeed looks like a very interesting year coming up.

Phil

I notice that we lose both Cassini and Juno within a few weeks of each other in the fall of 2017.

Predictions of end of mission that far ahead should be taken with a grain of salt, IMHO. Who knows what will happened to bring it closer or farther for both spacecraft, whether in the outer solar system or on Earth.

Happy New Year BTW!

Happy New Year to all as well!!!!

Re EOM for Cassini & Juno: It's possible that Cassini may get an extension, mostly because it's RTG-powered; presumably the prime considerations will be available power remaining, bus & payload health, and estimated remaining fuel for the ACS & main engines.

Juno will probably go as advertised since it is solar-powered & the Jovian radiation environment will cause significant deterioration of its own power generation capability over time.

In both cases, EOM must occur while the spacecraft are controllable in order to preclude the possibility (however remote) of either of them impacting a moon of interest for future detailed studies of organic chemistry & thus possibly introducing terrestrial contamination since, as orbiters, neither was sterilized to planetary protection standards for landers.

plus, Cassini and Juno will be taking more or less the same measurements (radio tracking for solid core probing and microwave radiometry) at the same time on both gas giants

Yeah. While i'm fully aware of all the issues involved: It's too bad they cant be put into a parking orbit for retrivial by future space exploration archeologist.

On a related issue i've been looking into the possibility of MSL taking images or videos of the Viking Orbiters. I've uncovered this discussion on UMSF from 7-8 years ago which suggest at least one of the orbiters may still be in orbit. Would it be possible for MSL to be programmed to return appropriate evening and morning images looking for objects in orbit? If so would it be possible to indentify the orbiter? We could "practice" on the existing 3 active orbiters ...

Probably sounds crazy but it might be a good use of extended down periods like the present.

It'll be pretty much out of fuel - Cassini won't be getting extended beyond the current 2017 schedule. And No, Eyesonmars - it shouldn't be left lingering - it needs to be responsibly disposed off rather than offer a contamination hazard for possible habitats.

Attempts have been made in the past to try and image orbiters in known orbits from the surface, without luck.

Ah; that's a hard constraint for Cassini. then. Thanks, Doug!

Great list, Paolo! pls, correct Mangalyaan dates (year 2012 is wrong)...

Cassini's fate will be determined as soon as they send it leaping over the rings into the Proximal Orbit phase. There's no way (energetically) to get it back out of that orbital configuration, and the orbit pretty quickly evolves into one with a pericrone of less than 1 Saturn radius (that is, it's gonna dip into the atmosphere, and that's the end).

I'm told that "Mangalyaan" isn't an official name. For what it's worth, ISRO seems to be employing Mars Orbiter Mission or (groan) MOM.

There is some uncertainty in the actual radiation environment, but the planned end of mission occurs shortly before solar conjunction and presumably the spacecraft would have to be in very good shape for any extension to be allowed.

When Juno and Cassini do their death plunge in a few years i for one will get a lump in my throat knowing there will not be another spacecraft returning data from the gas/ice giants during my lifetime - or for many of us on this forum.

Eyesonmars - I don't know your age, but don't forget the European JUICE mission will be in the Jupiter system in the late 2020s (and given my age, that may be my last outer planets mission. Dang, the decline in mission start rates is coming at a bad time for my retirement enjoyment.)

according to NASAspaceflight, launch of the Indian Mars probe is for 25 October.
this means that it would spend 1 month in Earth orbit...

I'm trying to come up with a list of future solar system missions for which there is actually hardware under construction. (This is my personal criterion for when I decide it's worth it to start paying attention to/blogging about a mission.) Problem is, I don't know which of these future missions are actually cutting metal. Can anybody help me out?

Here's the list of things I'm sure about:
MAVEN
Mars Orbiter Mission (Mangalyaan)
LADEE
Chang'E 3
Hayabusa 2
BepiColombo

I'm sure it's incomplete though....

MAVEN launches this year, so it's in advanced assembly and testing.
Same with LADEE I believe.
Hayabusa and BepiColombo also have hardware in development.

I don't know about the Indian and Chinese missions.

hardware for the TGO is being built, according to the ExoMars newsletters.
OSIRIS-REx maybe

Chang'e 3 is definitely being built. Here's a video of hardware and tests.
http://www.youtube.com/watch?feature=playe...p;v=IPqh5TxIteM

OSIRIS-REx's environmental assessment is still out for comment (deadline today), so I think they are not technically supposed to be under construction yet.

And since it wasn't clear, the list I posted was missions that I *know* are under construction. Thanks, Paolo, I'd forgotten about the TGO.

Great lists all, folks, thanks! And we'll now have to add to Paolo's list the MSL / Curiosity 2 (or whatever it'll be called) to be launched to Mars in 2020.

Might be funny to compare with a list I made a long time ago when I was little
