NAUTILUS-X[edit]

A NASA multi-center Technology Applications Assessment Team led from the Johnson Spaceflight Center, has as of January 2011 described "Nautilus-X", a concept study for a multi-mission space exploration vehicle useful for missions beyond low earth orbit (LEO), of up to 24 months duration for a crew of up to six. I have put a description into the "Electric propulsion" section, although the overall concept is flexible, and adaptable to various long-duration, low-thrust drive schemes.

This is clearly intended to flesh out some of the possibilities arising out of the change in NASA's direction announced last year, towards developing capabilities for missions beyond LEO. It incorporates various features that will be needed for interplanetary spaceflight in the next few decades: assembly, integration, and checkout in LEO, some kind of centrifuge for artificial gravity, radiation protection refuge against solar flares, long-term environmental control system, etc. It is modular, and clearly intended as a feasibility study for long-term refinement, rather than a detailed design. It strikes me as something some of us might actually live to see.

Suggestions for other good places to locate it might be helpful. We might want to have a new section, "Design concepts", for mission and vehicle designs that have been carried out to some level, as representative of the state of the art. The old Von Braun study "The Mars Project" could even be given as a concrete example from half a century ago. Wwheaton (talk) 05:33, 15 February 2011 (UTC)[reply]

When I saw the Nautilus-X concept, my jaw dropped as it seemed like one of the few proposals that has some really good merit that has come out of NASA's planning groups for some time. I've been quite impressed with both the depth of thought going into the idea and I'm intrigued by the idea that genuine spaceships (as opposed to spacecraft, like the distinction between a ship and a craft in nautical usage) could be built for interplanetary journeys and be built within my lifetime.
At the moment, I think there is really just one source of information for this concept, with some mention of it in a few space-related blogs and websites based upon that source. I strongly thought of writing an article about the idea, but due to a lack of sources it seems like there isn't sufficient information yet for its inclusion on Wikipedia except as a passing reference. If the idea gains traction and is discussed by Charles Bolden or some other significant sources of information come forward in terms of this idea being more fleshed out and it turning into a serious proposal as opposed to just another paper study, I think it would be worthy of inclusion. I really would like to get something put together about the idea, but it is premature at the moment to do much of anything with the idea. If more good sources of information can be found, I'd be more inclined to put something together and include that information in this article. It also would be an incredible article in its own right too. --Robert Horning (talk) 11:41, 15 February 2011 (UTC)[reply]
I am also a bit concerned about the shallow available sourcing, and agree that it is premature to give it an article of its own. The NASA site indicates this is a collaboration with representation from all the main NASA centers, not just a web posting by a couple of folks; based on that, I suppose the source is somewhat reliable. I have an email in to Holderman at JSC, asking for further advice either way. Like Robert Horning (talk), I am thrilled at any sign that serious work is being done at NASA about this, as the depth and detail of the presentation clearly indicates. I think we are in far better shape to explore the Solar System between Venus and Mars than we were to land on the Moon in May 1961, when Kennedy issued his famous Apollo challenge. Wwheaton (talk) 15:46, 15 February 2011 (UTC)[reply]
I have been in communication with Holderman at JSC, who seems to have no objection to his .ppt being linked here. He has sent me an updated version, dated March 2011, but I don't have a URL for that. Holderman also tells me they have a paper in work for the AIAA, and he will let me know when that is available. Once that is peer-reviewed and accepted, I think a stub/start stand-alone article might be considered. Wwheaton (talk) 21:33, 10 March 2011 (UTC)[reply]

Interplanetary mission[edit]

There appears to be an article which is effectively a duplicate of this one, Interplanetary mission. Any objections to moving over any relevant info from there and then making it a redirect? ChiZeroOne (talk) 19:18, 19 February 2011 (UTC)[reply]

None here.--Xession (talk) 19:57, 19 February 2011 (UTC)[reply]
Just make sure that all information is sourced, verifiable, and fits in with the narrative flow of this article. I've seen some botched mergers that are essentially a copy & paste, which simply doesn't work. Since the article you are proposing for merger here seems to be lacking sources, I'm not entirely sure what value it may have other than as a pure AfD candidate. Factual information which can be referenced from reliable sources may be suggested by this article and that certainly would be a useful addition, but it is going to take a bit more work than merely copying the content over. --Robert Horning (talk) 12:11, 20 February 2011 (UTC)[reply]
Surely not, but being a very similar topic, many of the sources on this article should apply for it as well. Some of the information of Interplanetary mission is unnecessary as well I'm sure. --Xession (talk) 16:48, 20 February 2011 (UTC)[reply]
There is no requirement on Wikipedia that all information must be explicitly sourced in an article, just verifiable. Only information likely to be challenged needs proper sourcing. I suspect nothing will require specific citation as as Xession says it should be adequately covered in present sources anyway.
Having said all that I completely agree with the sentiment of what you are saying. With only a quick look I agree It is unlikely much of that article will be of use anyway, but we should try to salvage what we can. ChiZeroOne (talk) 17:08, 20 February 2011 (UTC)[reply]
It seems to me that "Interplanetary mission" is a subset of "Interplanetary spaceflight", not a synonym. Maybe we could have an article with a list of missions which would give the basic specs (? which would be...??) of each of those, with those linking in turn to larger articles, as appropriate? Then we could have a "See also" link here to Interplanetary missions. Wwheaton (talk) 21:19, 10 March 2011 (UTC)[reply]

Venus orbiter misleading[edit]

The article contains a list showing what are implied to be the first spacecraft placed into orbit around each planet. But for Venus, shouldn't it show Venera 9? (sdsds - talk) 04:39, 9 May 2011 (UTC)[reply]

I have already corrected this. --D.M. from Ukraine (talk) 14:03, 24 December 2011 (UTC)[reply]

On-orbit tanker transfers: Presumably a composition error.[edit]

"SpaceX is currently developing a new spacecraft design that will, on all Earth-away launches, utilize the long-duration spacecraft (tanker or spaceship) to play a role briefly as the second stage of the launch vehicle to provide acceleration to orbital velocity. This approach is an unusual design approach launch vehicles designed prior to the 2010s."

My guess the second sentence was intended to be 'This approach is an unusual design compared to launch vehicles conceived prior to the 2010s.' or similar.

In light of the previous "Staging propellants" section which already describes the basic concept, may I suggest the following replacement for both sentences?:

'SpaceX is currently developing a system in which a reusable first stage vehicle would transport a manned interplanetary spacecraft to earth orbit, detach, return to its launch pad where a tanker spacecraft would be mounted atop it, then both fueled, then launched again to rendezvous with the waiting manned spacecraft. The tanker would then transfer its fuel to the manned spacecraft for use on its interplanetary voyage.'

I omitted the comment about this SpaceX system being relatively novel in part because I don't know how the concept evolved, and thus how much original inventiveness is attributable to SpaceX as opposed to others. And my sense is that it's not an appropriate subject to try to parse in the context of the Interplanetary spaceflight article anyway.

Comments and refinements eagerly welcome of course. If none after a few days I'll invoke the change. --H Bruce Campbell (talk) 23:34, 14 July 2017 (UTC)[reply]

Since no objections appeared I edited the article as described. But comments and refinements remain eagerly welcome of course. --H Bruce Campbell (talk) 08:46, 24 July 2017 (UTC)[reply]

Another "Economical Travel Technique": the Interplanetary Transport Network[edit]

The Interplanetary Transport Network could have use in robotic/AI satellite exploration and for shipping supplies to human colonies on the planets. It may even have some use for human exploration/settlement with "sleeper ships."

I'll leave it to folks who know more than I to add it to the main article. Phantom in ca (talk) 22:48, 11 November 2018 (UTC)[reply]

Proposed merge of Interplanetary mission into Interplanetary spaceflight[edit]

Obvious overlap with two concepts. Soumya-8974 talk contribs subpages 06:05, 13 August 2020 (UTC)[reply]

 Comment: The article Interplanetary mission has no references at all and would be WP:OR and without valid sources for claims made in the Interplanetary mission article it should probably be deleted and made a redirect. Interplanetary spaceflight already mentions multiple of the missions while figures appear to be "close" and imprecise in the Interplanetary mission article. Example: for the Mariner 2 mission it claims: "in December 1962 when it collected data within 35,000 km (22,000 mi) of Venus." whereas the actual values are: "its closest distance of 34,773 km at 19:59:28 UT 14 December 1962."[1] Terasail[Talk] 22:13, 15 September 2020 (UTC)[reply]

 Comment:. I concur. A redirect of interplanetary mission to interplanetary spaceflight is the correct option. I am going to redirect the article now. I don't plan on merging any of the information. I wouldn't object to other editors adding in information, but only selectively - not a block copy. Desertarun (talk) 16:46, 5 December 2020 (UTC)[reply]
