Review
 * Article is new enough, created on 14th December.
 * Article is long enough, it is currently 3460 characters of prose.
 * Article:
 * Is without bias (that I can tell).
 * Is well supported by citations (almost too well).
 * Large amounts of this article are copyvio and plagiarised, see 'Concerns' below.


 * Hook is within length at 130 characters and is formatted correctly.
 * Hook is interesting, supported by inline citations, and without bias.
 * QPQ check shows no other DYKs, therefore a review is not required.

Concerns: it utilises NASA wording verbatim in some places, such as: '...mission name is a reference to the lightweight and fast moving clipper ships of the 19th century that routinely plied trade routes on the high seas.' (the second paragraph of the lead and http://solarsystem.nasa.gov/missions/profile.cfm?MCode=EuropaClipper&Display=ReadMore )

'The notional science payload consists of six instruments: / Shortwave Infrared Spectrometer (SWIRS) / Ice-Penetrating Radar (IPR) / Stereo Topographical Imager (TI) / Ion and Neutral Mass Spectrometer (INMS)' (In 'Scientific payload') Vs. 'The notional science payload consists of four instruments: a Shortwave Infrared Spectrometer (SWIRS), an Ice-Penetrating Radar (IPR), a stereo Topographical Imager (TI), and an Ion and Neutral Mass Spectrometer (INMS).' ( http://solarsystem.nasa.gov/missions/profile.cfm?MCode=EuropaClipper&Display=ReadMore )

Although this does not pose a legal problem, it could still be considered plagiarism, and does not - for the purpose of DYK - count as new content. It is still above the 1500 characters, so I do not feel this qualifies to fail it though. But I would recommend these sections be rewritten, or the source of the text be better attributed (ie as a quote).

The text below does constitute a real problem:

'The trajectory of each flyby will bring it over a different sector of Europa. This will provide global medium-resolution coverage from the Topographic Imager.' (paragraph 2 of 'Objectives') Vs. 'However, the trajectory of each flyby will bring it over a different sector of Europa. This will provide global medium-resolution coverage from the Topographic Imager.' (paragraph 3 of http://futureplanets.blogspot.com.au/2013/05/europa-clipper-update.html )

'The Clipper team is also interested in the idea of hosting several nanosatellites that would be deployed in the vicinity of Europa. This is contingent upon the use of the Space Launch System (SLS) heavy lift launch vehicle; only that rocket would provide the needed mass margin required if the Clipper is to carry small satellite payload elements.' (paragraph two of 'Scientific payload') Vs. 'The Clipper team is very interested in the idea of hosting several nanosats that would be deployed in the vicinity of Europa. This is contingent upon the use of the Space Launch System (SLS) heavy-lifter. Only that rocket would provide the needed mass margin required if the Clipper is to carry small satellite payload elements.' ( http://futureplanets.blogspot.com.au/2013/05/europa-clipper-update.html first half of 21st paragraph)

'The Europa Clipper spacecraft benefits from the heritage of the Galileo and Juno Jupiter orbiters in its approach to radiation protection. The Clipper will utilize 150 kg of dedicated radiation shielding and will use a scheme of nested radiation protection for its electronics.' (paragraph two of 'Scientific payload' is word for word from http://futureplanets.blogspot.com.au/2013/05/europa-clipper-update.html 8th paragraph)

'Should a mission to Europa be accepted by the White House and NASA, an official budget request would have to be submitted in FY2015. The mission is currently estimated at around $2 billion.' (first paragraph in 'History' is verbatim from the last paragraph of www.planetary.org/blogs/casey-dreier/2013/20130905-no-asrgs-for-europa.html )

'In September 2013 it was decided that solar panels represent the cheapest option for the mission. Preliminary analysis suggests they would have the same surface area as NASA's Juno mission to Jupiter (9m x 2m) and provide about 150W of continuous energy while exposed to the Sun – equivalent to an MMRTG power source, which may still be the power source for the mission.' (last paragraph in 'History') Vs. 'According to Goldstein, solar panels represent the cheapest option for the mission. Preliminary analysis suggests they would have the same surface area as NASA's Juno mission to Jupiter (9m x 2m) and provide about 150W of continuous energy while exposed to the Sun – equivalent to an MMRTG power source.' ( www.planetary.org/blogs/casey-dreier/2013/20130905-no-asrgs-for-europa.html paragraph 9)

'The Europa Clipper's orbit has a low inclination causing it to pass through a most intense radiation environment ... This would cause aggressive degradation of solar cells, such that their power output would be increasingly compromised as the mission progressed.' (middle of final paragraph in 'History' is verbatim from http://futureplanets.blogspot.com.au/2013/05/europa-clipper-update.html middle of 12th paragraph)

'A safer power source is the MMRTG, but it would require most of the remaining U.S. supply of plutonium-238, and current space policy dictates the use of solar panels unless the use of RTGs is absolutely necessary.' (last paragraph of 'History') Vs. 'But since MMRTGs are expensive, would eat up most of the remaining U.S. supply of plutonium-238, and the fact that current space policy dictates the use of solar panels unless the the use of RTGs is absolutely necessary or significantly increases the chances of mission success, my bet would be on solar panels for the Clipper.' (third last paragraph of http://www.planetary.org/blogs/casey-dreier/2013/20130905-no-asrgs-for-europa.html )

Sorry, but due to the large amount of copyvio and plagiarism I'm failing this DYK. if it were less wide spread I would have been more tolerant, but as it stands at least half of the article is problematic (and that is all I have found). I think that when all this text is removed, and with the possibility of finding more copyvio or plagiarised text (the PDFs still have to be checked) the article will be well below 1500 characters.
