Suggest adding comment in bold for Apollo 15 - First Lunar Rover. This was a significant first in lunar exploration as it allowed much greater range of manned exploration. Tony (talk) 20:49, 8 September 2009 (UTC)
This page should probably be move to something like Timeline of solar system exploration as it is not limited to actual planets. It already includes comets, the sun, etc. Rmhermen 00:32, Mar 25, 2004 (UTC)
Do missions that have been cancelled really belong in this topic (either in the "past" or "planned" section)? JTN 19:14, 2004 Aug 10 (UTC)
Are Chinese missions included?
I reverted the additional of nationalities and national firsts added by a recent anon editor. This is already covered in the similar list List of planetary probes which is organized by target instead of by time sequence. I don't think the origin needs to be duplicated and I especially disagree with the national firsts. Opinions? Rmhermen 15:09, 4 February 2006 (UTC)
I put the date of the first postwar V2 launch to get past 100 miles in the timeline. You've got to start somewhere, and the first verified unmaned spaceflight is as good as any. —The preceding unsigned comment was added by 66.108.2.161 (talk) 16:13, 16 December 2006 (UTC).
I'd appreciate thoughts on whether the following items should be left in or not:

I'd say keep everything with a scientific payload that made a notable first in terms of area directly accessed (100km sub orbital, Earth orbit, etc). Human spaceflight should probably follow a similar pattern (i.e. Vostok 1, Apollo 8, Apollo 11) or be cut altogether. Space telescopes should probably be cut as outside the scope of the article unless we want to include notable telescopic discoveries generally since their location is of secondary importance when it comes to exploration. In any event JWST should be treated the same as Hubble. Eluchil404 12:11, 15 March 2007 (UTC)
Mars 2 wasn't the first Mars orbiter. Mariner 9 got there before Mars 2. Shrewpelt 17:39, 1 September 2007 (UTC)
This totally ignores the Vikings progress. —Preceding unsigned comment added by Shark113 (talk • contribs) 00:51, 8 May 2008 (UTC)
i can't find any reference to Venera 1964B on the Venera page, would someone like to add it to that page or should there be no link at all?--Lord Aro (talk) 12:41, 14 May 2010 (UTC)
Question: Should missions that failed at launch (launch failures) be included? I'm inclined towards the 'no'...--Lord Aro (talk) 13:49, 7 February 2011 (UTC)
The description for Voyager 1 states that it was the first to leave the Solar System, but on the Voyager webpage from JPL it says that it has not technically left the Solar System, merely passed all the planets in the System (http://voyager.jpl.nasa.gov/faq.html). Should this be corrected? ThatKidFromWhere (talk) 15:02, 13 March 2011 (UTC)
All spacecraft have a national flag, showing which nation launched them, but half appear named after the nation eg "Chinese lunar rover" and half just contain mission type "lunar rover" - I'll update to make consistant Philadelphia 2009 (talk) 11:51, 30 May 2011 (UTC)
Is there a flag or flagicon for the European Space Agency (ESA)? Lord Witwenmacher (talk) 12:57, 26 January 2019 (UTC)
Should space stations be included? I'm heading towards the 'no' as they are Earth orbiters, not 'exploring the solar system' as this page is for. (I think the first space station should stay though) - Lord Aro (talk page) 09:32, 2 June 2011 (UTC)
should the notable space shuttle missions be included? I'm thinking first and last should - Lord Aro (talk page) 10:36, 14 July 2011 (UTC)
Someone needs to include something in the Planned or Scheduled section of the article about Mars One.
From the website:
Mars One will establish the first human settlement on Mars in 2023. A habitable settlement will be waiting for the settlers when they land. The settlement will support them while they live and work on Mars the rest of their lives. Every two years after 2023 an additional crew will arrive, such that there is a real living, growing community on Mars. Mars One has created a technical plan for this mission that is as simple as possible. For every component of the mission we have identified at least one potential supplier. Mars One invites you to join us in this next giant leap for mankind!
--Kluutak (talk) 21:00, 3 August 2012 (UTC)
Mars One is looking more promising now, and their website is also much better. It certainly seems like they have a good chance of making it work, it's really a matter of funding. They have a 2018 orbiter, 2020 rover, and 2025 human landings planned. (www.mars-one.com)
SpaceX also has Mars colony plans that are much moe likely than Mars One. Elon Musk says he could land the first people on Mars in 2026, and if that doesn't work, an early 2030s time-frame is very likely. This article should at least mention one of these plans. Smt98 (talk) 02:35, 13 November 2014 (UTC)
Added a timeline chart in the gallery section (don't know if it's the right one). Maybe the picture needs to be tweaked, every suggestion is appreciated. Don't know if this is the correct page (there is also "Discovery and exploration of the Solar System" and "List of Solar System probes").FraPado86 (talk) 15:18, 1 December 2014 (UTC)
Thanks, i will try to implement the picture with a better legend right away. FraPado86 (talk) 11:08, 2 December 2014 (UTC)
Added more explanation below the picture and changed its position in the page since I think it doesn't belong to the gallery section and I guess it would be good as an introductory image. I tried to respect all the guidelines that are given in the list of mission, and if anybody finds out that some mission is missing or some other shouldn't be there it can be edited. FraPado86 (talk) 14:45, 3 December 2014 (UTC)
What's up with that merge proposal from May 2014? Moving content from Space probe#Some notable probes into this article? I can't see any discussion going on nor any reasoning for that change. Well... for what it's worth: I Disagree, it'd basically mean permanently removing an entire section, while it is quite valuable highlighting some notable probes. That said though: I think this section in space probe article needs an improvements: at a very least adding ((see also|Timeline of Solar System exploration))
and altering it's name to one that's more... serious. SkywalkerPL (talk) 08:25, 1 August 2015 (UTC)
Why do Pioneers 10 and 11 appear on the "interplanetary" space section, and the Voyagers 1 and 2 on Jupiter, when all 4 ships where intended for interplanetery space at the end, and first thrown to fly-by Jupiter for gravity assists (and the Voyagers and Pioneer 11 fly-by Saturn, and Voyager 2 Uranus and Nepture too..).
Why is no proper section for Uranus or Neptune, and there is a section for Pluto??
That graph is awesome for 1-objective only missions. For all of the moon mission or others it is AWESOME and very detailed, but for multi-flyby's missions like Voyagers, Pioneers and even New Horizons it is just terrible. Also for example Rosetta did in total 3 gravity assist to Earth, one to Mars, fly-by'ed 2 asteroids and ended up at the comet, where is all that information?
That graph could be excellent with horizontal lines and those multi-celestial body missions getting on every section where they belong. For example Voyager 2 starting on Jupiter, then moving to Saturn section, then moving to Uranus section, then moving to Neptune section, and ending up on Interplanetary Space. There should be also an Interestelar section for Voyager 1.
Also if there's a section for Titan, why there isn't one for the rest of moons which had been fly-by'd also? the fact that huygens landed there isn't enough to justify a section for itself and not the others.
Don't consider me wrong, that graph is awesome for the most part, but it should re-made the sections in order to reflect the missions with multi-visits, add new sections for the proper missions to planets, order them properly (pluto shouldn't be the last after comets and interplanetary space..) and if needed separate it in 2 versions for the moons to get extremely good detailed graph of every single fly-by :)
EDIT: There is also too much blue stuff and it's very hard to diferentiate all those sections using closely shades of blue for a normal person.

Is there a flagicon for the European Space Agency (ESA)? Because actually it is the ESA which conduct the european space missions and not the European Union. — Preceding unsigned comment added by Lord Witwenmacher (talk • contribs) 11:40, 2 April 2019 (UTC)
The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.
It seems terribly redundant to have this article, Timeline of space exploration, and Timeline of the Space Race when they overlap so much. I can kind of see the point in having a separate one for the space race, but I can't quite figure out why this one exists. The main thing it adds compared to Timeline of space exploration is the "Planned or scheduled" section, which I think should probably be made into its own article anyway. The main reason I'm taking this to the talk page instead of just WP:BOLDly merging it myself is because I want to know if there is any good reason why these articles were made like this in the first place. A secondary reason is that I'd like some input as to what the new article about future missions should be called. TompaDompa (talk) 11:34, 14 April 2019 (UTC)
What do you think, would a success/failure column with ((success)), ((failure)), ((partial success)), etc. improve the article? TompaDompa (talk) 08:13, 20 April 2019 (UTC)
According to https://www.rocketlaunch.live/launch/lunar-scout
currently foreseen launch date is July 2020. Nothing new from Moon express themselves, which could be interpreted as "not anytime soon". I would suggest to either move to 2020 or remove for the time being. — Preceding unsigned comment added by 131.176.243.9 (talk) 07:12, 16 May 2019 (UTC)
This page has several entries for missions with launch dates in the future, some very far into the future. I have removed some of these entries (though they have since been re-added by other editors, which is why I'm bringing this up here on the talk page) for not meeting the requirements for inclusion when it comes to sourcing. In particular, they fall short of WP:FUTURE (Individual scheduled or expected future events should be included only if the event is notable and almost certain to take place.
—I would especially draw your attention to the latter part) and WP:EXCEPTIONAL (Any exceptional claim requires multiple high-quality sources.
). There is also the issue of WP:RUMOUR (Wikipedia is not a collection of product announcements and rumors. [...] Speculation and rumor, even from reliable sources, are not appropriate encyclopedic content.
). Including these entries is contrary to Wikipedia's mission as an encyclopedia. We are WP:NOT here to conduct PR for space agencies, which is what we are in effect doing by uncritically listing their aspirations here. Nor are we here to predict the future.
The argument that has been made for retaining these entries, we can say that none of these are almost certain to take place
, misses the mark by a staggering amount. Firstly because it works better as an argument for removing all the entries rather than retaining all the entries, and secondly because there is a world of difference between something like the James Webb Space Telescope—where we have a set launch date sourced to NASA, the sources are up-to-date, and the telescope has been assembled—and something like the crewed phase of the Chinese Mars exploration program—where we have a single source from thirteen years ago, that source is the Chinese military, and what it says is that anonymous sources speculate that it may happen in a few decades[a]—or Chang'e 7—where the source is The Planetary Society (basically a space exploration fan club) and it outright admits that it is all very uncertain as of the date of publishing.
Part of our job as editors is to assess the WP:RELIABILITY of the sources, not just uncritically repeat what they say. An important aspect of that is that WP:AGE MATTERS—in this field delays, cancellations, and changes in plans in general are very common, which makes sources become outdated extremely quickly (five years is old, ten years is ancient). This also means that statements about the future get increasingly dubious the more distant the future events are; most events more than five years away are largely speculative, and anything more than ten years away is pretty much pure guesswork.
This is not Category:Proposed space probes or List of proposed space observatories. This is Timeline of Solar System exploration. These highly speculative "future event"-type entries do not fall within that scope. There may be a place on Wikipedia where this material belongs, but this page is not it. TompaDompa (talk) 00:17, 13 October 2019 (UTC)
I went ahead and created Draft:List of proposed space probes. By having such a page, we can remove this poorly-sourced garbage content from this otherwise well-sourced article. TompaDompa (talk) 19:00, 7 November 2019 (UTC)
Notes
There are even space experts who envision that China will realize unmanned Mars exploration between 2014 and 2033, and manned Mars exploration from 2040 to 2060.
