Findings
The findings section is a bit silly... it simply lists how things were found, not what was actually found or what it means. I think a lay interpretation of the findings and implictions thereof is mandated. — Preceding unsigned comment added by 105.236.156.139 (talk) 05:19, 11 November 2013 (UTC)

Most beatuiful sat.
Should this also be included,it has been refered as this by many news papers. '''yousaf465'

will be or is?

 * Other payload will be an onboard GPS receiver used as a Satellite-to-Satellite Tracking Instrument (SSTI)

I presume this should be 'is' not 'will be' - if it has been launched into space, I doubt any more instruments are going to be added to it. But maybe it wasn't put on, I know nothing about the subject. --86.128.12.102 (talk) 19:36, 19 March 2009 (UTC)

Capabilities?
So what can this do that GRACE cannot? —Preceding unsigned comment added by 76.191.224.198 (talk) 04:43, 24 May 2010 (UTC)

At the end
Does anyone have a source for a (continously updated) prediction of reentry-time and -lokation --Itu (talk) 22:12, 7 November 2013 (UTC)

The re-entry is expected to occur between 18:30 UTC - 24:00 UTC, Sunday, 10 November? Isn't it already past 18:30 UTC? --Uncle Ed (talk) 21:33, 10 November 2013 (UTC)

15 to 20 square yards
I am removing the assertion Debris from the satellite are expected to endanger an area from 15 to 20 square yards. from the article. Editor Ed Poor reverts my edit.

The idea that the re-entering satellite's broken up pieces will neatly deposit themselves on the area of a small rug is obviously quite silly.

Here is how various web sites report the claim:


 * "debris will endanger anyone within 15 to 20 yards of the impact."
 * "the largest piece of debris will cover around 15 to 20 square yard"
 * "debris will endanger about 15 to 20 square yards of the Earth's surface."
 * "will affect an area approximately 13 to 18 metres squared."

So which is it? You are ok if you are further than 15 yards from a falling piece, or the largest piece will be 4x4 yards in size, or there will be hole in the ground of 4x4 yards, or a hole of 13x13 meters (10 times bigger than the 4x4 hole)? Maybe we shouldn't participate with the press playing Chinese whispers.

It's not about whether the "source is an astrophysicist", it's about if the reporter between the astrophysicist and us has a brain on his shoulders, and most press don't. Please think if a re-entering satellite lands in a neat tiny pile. (Sorry about the long rant, didn't have the time to make it shorter.) 88.112.41.6 (talk) 00:26, 11 November 2013 (UTC)

As one fairly experienced (PhD in physics, 40+ years working in astronomy) in space science and astrophysics, I feel qualified to say the quote is absurd, regardless of the source. The speaker must have meant the actual size of the impact area—the crater, essentially—from any debris that might survive reentry. The chance of a person being in that small area would be a fair estimate of the chance of anyone actually being struck by debris. The region where debris might fall is much much larger, and therefore all in some danger, however slight. The size of that region gets smaller rapidly as reentry is approached, but the size of the final debris field is controlled by the details of the spacecraft's construction, exactly how it happens to break up in the atmosphere, high altitude winds, etc. As a spacecraft is still traveling nearly 300 km/min as it reenters, and the process takes a few minutes, the field is very long and narrow, approximately elliptical. It is typically up to several hundreds of km long in the direction of travel, and perhaps over 10 km wide transversely. Thus ~1000 sq km would be a more reasonable estimate of the endangered region as late as a few minutes before the first debris hits the ground. For a rather small satellite like GOCE, it is not clear that any debris at all would reach the ground. Heavy stuff made of high melting temperature materials should land near the farthest end of the ellipse, but light debris may survive and come fluttering down near the beginning. I hope this may clarify the discussion a bit, as we don't want anything ridiculous in the article. Wwheaton (talk) 02:42, 11 November 2013 (UTC)

Wikidata structured data, nice structure assessed here, curiosity defines possible break-throughs in Properties structure.
Gravity Field and Steady-State Ocean Circulation Explorer is a page destination from WikiSearchbox with string data: GOCE; the which was my intention to find the Guild of Copy Editors. Grammatically GoCE. Anyway, fate brought me here. This article is being considered for nomination to Good Article standing. Nicely done. I see it as being potential for great things relating to Data structure.
 * Plans to experiment with this portal to the KOW using an image of this article; with specific intention Not to to avoid disrupting your page in any way. I'll be awaiting any response to this offer; of which is designed to coordinate a WikiData Showcase. I'll be watching this Subject/headline; to which I'll be back as someone has made the phrase famous. Paptilian, PpT'lln , ( P. sig'd   ). . 15:40, 17 December 2020 (UTC)
