Update for Timeline - re attitude monitoring/control[edit]
Veteran Mars probe looks to the stars for longevity says the primary inhertial sensor (gyroscopes) was switched off a while ago and the backup has been used, and now 2018 they are testing a software upgrade to avoid relying on the inhertial sensors at all. "The primary system was already switched off a few years ago after it clocked up 58,000 hours of service, and NASA says that the backups have now reached 52,000 hours."

In the "Mission Objectives" section, the article lists the rovers and landers that MRO helped choose the landing sites for, but there is an inconsistency there. Most of the missions are listed with the years they landed on Mars. Curiosity is listed as 2012, when it landed, instead of when it was launched in 2011. Same thing with Perseverance. InSight launched and landed in the same year, so there's no difference there. But Phoenix is listed as 2007, its launch year, instead of its landing year, 2008. This just confused me, I'm not sure if it's really an issue or not, I just wanted to point it out. 185.163.72.18 (talk) 19:39, 20 January 2023 (UTC)[reply]
Thanks for pointing it out! I've changed the Phoenix lander to match the others, changing the year from the launch year, 2007, to the landing year, 2008. ARandomName123 (talk) 20:21, 20 January 2023 (UTC)[reply]
The discoveries and photographs section has a lot of images, especially images of other spacecraft. The articled itself also has a ton of images, some of which, in my opinion, should be moved. Additionally, the MRO produces thousands of images a year, so more recent photos could be added to a new gallery section. Thoughts? ARandomName123 (talk) 17:33, 2 February 2023 (UTC)[reply]
The orbiter makes tons of discoveries, so the discovery section should be as brief as possible, only 1 picture per discovery listed if that. And the tectonic fractures picture in the timeline seems completely unnecessary. It looks like there is a gallery section, but it only has 2 pictures and they're of the same thing. Maybe a few of the unnecessary pictures in the rest of the article could go there instead, as well as a few more recent photos (if you need those I can supply them, I spend a lot of time looking at the HiWish map) such as pictures of the rovers and any interesting discoveries the orbiter makes. DragonGirlStar (talk) 15:25, 5 April 2023 (UTC)[reply]
The discovery section used to be even more cluttered, since it used to include all the images in the gallery section. The gallery section has more than two images, but we should probably remove one of the duplicates. The tectonic fractures picture could be replaced by a variation of the Victoria crater image, where the rover mentioned in source 24 circled. The image in the source is pretty good. If you could supply some interesting recent photos, that would be great, thanks. I'll move some unnecessary pictures to the gallery when I have time. ARandomName123 (talk) 18:05, 5 April 2023 (UTC)[reply]
Here's a few HiRISE pictures, I might get more later if you think I should. The first is of Melas Chasma, the second is of Perseverance (in the center - I forgot to mark that when uploading, but it's kind of obvious so that's fine), and the third is of InSight and its hardware. DragonGirlStar (talk) 20:16, 5 April 2023 (UTC)[reply]
Alright, I'll get some when I have more time, I'm kind of busy right now. I just figured the rover pictures are usually what people are more interested in, but you are right that there's a lot. Do you have any regions/styles/formations you think should be in more pictures, or just any interesting one I come across? DragonGirlStar (talk) 16:37, 6 April 2023 (UTC)[reply]
It's fine, take your time. For the pictures, I guess just choose some interesting ones, or some linked to some recent discoveries. I'm planning to update that section in the future. ARandomName123 (talk) 21:23, 6 April 2023 (UTC)[reply]
Here's two more, both unnamed craters. I'll get more when I have free time, but I have some good ideas.
Here's two more, one of dunes near Mars's north pole, and the other one is something I think the average wikipedia-goer will like: the exact coordinates that the book The Martian is supposed to take place. This page probably gets a lot of sci-fi fans, so I think that would interest them. (first one is the book site, second is the dunes)
I can find more squarish ones, but the HiWish website doesn't have the images in full color, only partial color. There should be some with full color on the various HiRISE social media accounts. I know they publish a lot of its images in color on Twitter, but I'm not allowed on Twitter, so if you want to check that you probably could. I'll grab some with the square proportions. DragonGirlStar (talk) 13:06, 19 April 2023 (UTC)[reply]
I got some that aren't nearly as long, HiRISE images don't usually come in squares and when they do it's areas that have already been photographed many times so these were hard to find.
Oh shoot. Sorry, I was stressed about exams at around that time, and it completely slipped my mind. Thanks for reminding me. I'll add in the long one with the big crater, the one with the dunes, and the one after that. If you think more photos should be included, feel free to add them in. ARandomName123 (talk) 16:49, 26 May 2023 (UTC)[reply]
They don't have to be rotated, but I think it'll fit better on the page. Also, do you think we should remove 1 or 2 images from the "Other spacecraft" section? More specifically the second and fourth photos. The gallery section is filling up pretty quickly, and the images mentioned are blurry, and don't add much to the article.

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.
missions to Mars - consider unlinking, as the link leads to an article that is only about past missions, not future ones. I would link Mars here instead.
The references are used to cite uncontroversial information, and as this information should already be stated in the main text of the article, they are are not needed here.
Partly done: I left the source for the stat about data returned, since it's not in the body. I'll add a mention of the data returned stat when I get access to my laptop. Mobile editing is painful. ARandomName123 (talk)Ping me!19:07, 13 August 2023 (UTC)[reply]
Something like this image would be better used in the infobox than the current one.
However this has been reverted by another editor, imo for no good reason. I'll message this person. AM
JPL - use the full name, as the abbreviation will be unfamiliar to many readers (see MOS:ABBR). Ditto APL / ASI.
MRO - if the full name of the spacecraft is written in italics, the abbreviation should be as well.
The launch image is purely decorative. By removing it, a sandwiching issue in this section also disappears (MOS:SANDWICH).
I think we should keep the launch image. A large portion of spacecraft articles contain one, and it helps as a visual aid. To avoid the sandwiching issue, it could be moved to the other side, once one of the animations has been removed. ARandomName123 (talk)Ping me!00:26, 20 August 2023 (UTC)[reply]
The second animation provides little to helps understand the text, and is not visually useful after a few seconds (the pink orbit lines turn into a block of colour). I would declutter this section by removing the image.
Mars Global Surveyor and the rovers Spirit and Opportunity have since ceased – this, and the text that follows, should be edited out as being excessively detailed, or placed in a separate note. I would do the former.
This altitude depends on the thickness of the atmosphere because Martian atmospheric density changes with its seasons – this should be cut, as it strays off the topic.
Mars Reconnaissance Orbiter - as these has been abbreviated as the MRO in the Pre-launch section, I would be consistent and from then on use the abbreviation instead the full name.
afaik, it has something to do with how space is too cold for technology to operate, so instruments and tech needs to be "warmed up" to be able to function. if you need further clarification just lmk. ARandomName123 (talk)Ping me!01:46, 20 August 2023 (UTC)[reply]
enabled discoveries regarding – ‘that have revealed more of’ sounds slightly better imo.
The section’s images have created another sandwiching issue, which needs to be sorted.
I would replace terrain with ‘relief’ (a minor point).
(CO2) is not needed.
is slightly - ‘was slightly’.
(not GA) the best ever pictures of a comet from the Oort cloud – is an image available? Readers might be interested (and it would break up the text somewhat).
ok, well an image is available but it looks a bit less interesting as I thought it would look. See: [1]. I'll leave the decision up to you. I can probably use a different image though, probably from the gallery, to break up the text. ARandomName123 (talk)Ping me!01:46, 20 August 2023 (UTC)[reply]
components - consider amending to ‘MRO components’.
Mostly Done: I need to do a bit more research about the banded terrain part, as it's lacking a source, but I think terrain would be better. ARandomName123 (talk)Ping me!01:46, 20 August 2023 (UTC)[reply]
5 Instruments
NThe last two sentences need to be copy edited, the information is outdated.
Done. I've added some missing info about some science experiments, so you might want to check "Engineering instruments and experiments" again. ARandomName123 (talk)Ping me!20:13, 18 August 2023 (UTC)[reply]
The images for the main instruments are rather too large for the paragraphs they are placed next to, and imo causes this section to look untidy. One solution to consider to to put them images together here, at the top of the section, using {{multiple image}}. Happy to help here if you want. Amitchell125 (talk) 13:25, 14 August 2023 (UTC)[reply]
I would amend the title to HiRISE, as the acronym has already been introduced. Ditto the titles from 5.2 to 5.6, the abbreviation/acronyms for these have also been mentioned.
(μrad) – is redundant. Ditto or NIR.
''28 Gigabit (Gb) – consider amending this to ‘28 Gb’.
The shutdown of CRISM has already been discussed in the Timeline section. Considering the size of that section, I would move the relevant paragraph from there to here, and edit out any duplicate information.
Comment: I've shortened the shutdown sentence here to "The CRISM instrument was shut down on April 3, 2023," but I think leaving the more detailed explanation in the Timeline section would be better. ARandomName123 (talk)Ping me!21:38, 16 August 2023 (UTC)[reply]
velocity – this has a specific meaning in physics that is not the same as speed (see Velocity). I would amend the text to say ‘speed’, unless the technical term is intended.
proven its functionality by relaying – simplify to ‘relayed’?
Although moon imaging is not mission critical – ‘Although this is not critical’ sounds better imo.
There is a proposal to search for small moons, dust rings, and old orbiters with it - a few points here. Which “old orbiters” are being referred to here? Can information about the proposal be updated, as we are talking here about an idea brought up over 10 years ago? Who proposed the idea?
All Done: For the proposal, I don't think it was ever followed up on; searching the title only gives this source, it doesn't seem like any of the suggested tests have been done, and the MRO isn't mentioned in this capacity in any of the sample return documents I've checked. I've decided to remove it. ARandomName123 (talk)Ping me!21:38, 16 August 2023 (UTC)[reply]
6.2 Power systems
more than 26% of the Sun's energy – amend to something like ‘more than 26% of the Sun's energy it receives’ so that the text makes more sense.
At Mars – ‘Whilst orbiting Mars’ sounds better imo.
The Electra communications package is a UHF software-defined radio (SDR) that provides a flexible platform for evolving relay capabilities – this sentence and the one that follows are already to be found in Engineering instruments.
is projected to be – should presumably now be amended to ‘is’.
such as launch – as this has now happened, the text needs to be amended.
The Ka-band subsystem was used for demonstration purposes – consider amending to something like ‘The Ka-band subsystem was used to show how such a system could be used by spacecraft in the future’ to make the text easier to understand.
The caption does not fully explain the image. It isn’t drawn to scale (and this isn’t stated on the image itself), so I would mention this in the caption. The image needs to be moved to so it sits beside the text, not underneath it.
Graph is pretty outdated, being created before the MRO was even launched. There doesn't seem to be an updated version from NASA (afaik), so I've removed it to free up some space for an image from the gallery. ARandomName123 (talk)Ping me!21:47, 22 August 2023 (UTC)[reply]
accelerometer - Move the link to where it first appears (Engineering instruments).
Consider avoiding using the five subtitles here. Removing them wouldn't make this section overlong. I would then place the images together at the bottom of this section, something that imo unifies the text and makes the section less cluttered.
Mostly Done. I merged the related subtitles together (Ice + ice and chlorine + aqueous). I kept the subtitle for the slope lineae mainly to preserve {{main article}}. Now that there are three sections for three images, I think keeping them at their respective section should be fine. Feedback is appreciated, though. ARandomName123 (talk)Ping me!16:14, 20 August 2023 (UTC)[reply]
Looking again, I'm not sure the main article hatnote is appropriate here, as the link leads to an article that is not directly about the MRO, and so it is off topic. Amitchell125 (talk) 07:51, 21 August 2023 (UTC)[reply]
with the Compact Imaging Spectrometer (CRISM) on board the Mars Reconnaissance Orbiter - simplify to ‘using CRISM'.
five locations. Three of the locations are in the Cebrenia quadrangle – amend to ‘five locations, three of which were in the Cebrenia quadrangle’ to improve the prose.
This set of galleries (and therefore the subsections) are superfluous, as the images are available in the Common category associated with this article (see WP:GALLERY). Any of the images can be used to illustrate the text (and there is room for them), they should be be moved to the right place in the article.
Done. Removed gallery section, was able to move around 4-5 images back into the article. Might want to check image placement, since a few of them are only related to the text they are placed next to through only 1 or 2 sentences. ARandomName123 (talk)Ping me!21:45, 22 August 2023 (UTC)[reply]
What makes you think space.com is a reliable source? Ditto spaceexplored.com; https://spaceflightnow.com.
WP:RSP? Author qualification looks fine as well. As for the other two, spaceexplored.com has been removed as part of the excessively detailed bit about the missions, and I'm working on finding a replacement for spaceflightnow.com. ARandomName123 (talk)Ping me!02:00, 20 August 2023 (UTC)[reply]
Thanks for WP:RSP, a useful link I was unaware of. AM
As the New York Times is a subscription service, consider adding a ‘url-access=subscription’.
''NASA's Mars Reconnaissance Orbiter page – should probably be removed, as the official website is already provided in the infobox.
MRO Mars Arrival Press Kit (2006) – can easily be found in the offical MRO website, so isn’t needed here.
Interactive 3D map of Mars created by CTX – this map is produced from MRO equipment, but is not directly connected with the spacecraft itself, and so the link should be removed.
(Not GA) Consider collapsing the navboxes using {{Navboxes |title=Articles and topics related to the Mars Reconnaissance Orbiter |state=collapsed |list1= {{Mars Reconnaissance Orbiter}} {{NASA navbox|state=collapsed}} {{Mars spacecraft}} {{Jet Propulsion Laboratory}} {{Solar System probes}} {{Orbital launches in 2005}} }}.
HiRISE Image Catalog – this is easily located in the external link given in the previous subsection, and so is not needed here.
Aren’t Kevin Gill’s images included within the HiRISE Image Catalog? If so, I wouldn’t include this external link. I have added it to the external links section of Areography.
I'm putting the article on hold for a week until 26th August to allow time for the issues raised to be addressed. I'll start checking the work you've already started on the review (many thank for this), crossing out where issues are sorted, and adding a small red cross (N) if they are not. Regards, Amitchell125 (talk) 06:43, 18 August 2023 (UTC)[reply]
Added to See Also. All of the GA related stuff has been dealt with, I believe. The final thing is the cn tag I added, which will probably be completed in a few hours.
About the infobox image, I kind of agree with what both of you said, so how about one of these two images (cropped, if neccessary)? [4]or[5] This image has a background and also contains a slanted view of the orbiter, so it shows more of the spacecraft. ARandomName123 (talk)Ping me!22:08, 22 August 2023 (UTC)[reply]
Everything should be done. The sentence with the final cn tag was removed since I couldn't find a source to support it. Regardless, it sounded a bit weird being in the "Timeline" section, and looks more similar to RSL than banded terrain, since banded terrain is suspected to be caused by ice, not liquids.
