Stub

Hey all. Are we really still just a stub, or is it time for us to take away that walking stick? Tuvas 20:13, 24 May 2006 (UTC)

Ion Thruster ≠ Arcjet

The article says the University of Illinois cubesat employs "ion thrusters", but AFAICT, the linked site (i.e. http://cubesat.ece.uiuc.edu/ ) describes an arcjet system, which also has an article: http://en.wiki.x.io/wiki/Arcjet

They are not the same technology. I suppose the confusion is unsurprising considering that the satellite is called "ION" (but that's an acronym for "Illinois Observing Nanosatellite"). I imagine they would mention an actual ion thruster if they had one, as it is a more challenging technology than arcjets.

If the source above is the basis for the ion thruster claim, then it should be changed to read "arcjet" and link to that article instead.

I should've caught this last year, but anyhow it's finally fixed. Dawnseeker2000 16:19, 7 November 2009 (UTC)

 Done. Better now than never. Cheers, BatteryIncluded (talk) 17:50, 21 May 2015 (UTC)

Clydespace

Are the references to clydespace really appropriate? To me they look added more like a commercial for the company rather than for any real reason. Is there a purpose to including them?

The reason for including Clyde-Space and other suppliers in this article as a reference is to broaden the readers knowledge of the ongoing development and education into Cubesats and their subsystems.

I agree - not only should we list Clydespace but several other providers such as Pumpkin and Gomspace. Are there specific rules against this? --Scasey1960 (talk) 03:18, 4 May 2010 (UTC)

We can discuss the companies that provide hardware and include secondary references (not Clydespace themselves). This would be a good improvement to the article; something more than a list of links. Here's the article before I started working on it. It was mostly a list of links. It was a lot of work to actually make prose out of all the possible sources, but I did it, and learned quite a bit in the process. Dawnseeker2000 03:40, 4 May 2010 (UTC)

PW-Sat

PW-Sat is the first polish satellite and it'll be launched on Vegas. PW-Sat is on the ESA's list of CubeSat: http://www.esa.int/esaED/SEM2BPUG3HF_index_0.html —Preceding unsigned comment added by Maciejurbanowicz (talk • contribs) 23:14, 5 December 2008 (UTC)

Excellent! I've already used the ESA page that you provided as a reference in the article. Thanks :D E_dog95' ^{Hi '} 23:28, 5 December 2008 (UTC)

I updated information about PW-Sat. I'll create an article about PW-Sat soon. --Maciejurbanowicz (talk) 10:29, 6 December 2008 (UTC)

MASAT

Hi! There is a Hungarian CubeSat project called MASAT-1:

Naming

The Cal Poly naming conventions state that Cal Poly should be two words, and this is the only shortened version accepted by the University. The versions without the space should not be used, unlike at CalTech. I'll change it when I have a chance. Rico (talk) 17:12, 26 March 2010 (UTC)

KickSat

Should we add a mention of the KickSat project to this article or to the List of CubeSats? Someone has already written up a bunch of KickSat references, so that part has been done for us. Wingman4l7 (talk) 05:00, 25 October 2011 (UTC)

This article has a few items listed, but they're examples of specific types of Cubesat missions. These don't look like they fit the Cubesat standard anyway. The KickSat is a miniaturized satellite. Dawnseeker2000 16:38, 25 October 2011 (UTC)

The Kickstarter page states that the Sprite micro-satellites will be deployed from a CubeSat. Maybe the best option would be just to keep an eye on the project and add it to the List of CubeSats when it launches? Wingman4l7 (talk) 23:51, 25 October 2011 (UTC)

the_FTI-1 minisatellite project is from belgian liege university and the team keeps it running. the website for the project:USAhomepage project; please translate whats worth 4an article because i want to find out what ic`s they use in altitude control circuitry.thx;p188.25.108.129 (talk) 09:38, 27 June 2012 (UTC)

Stats by year

Since more and more CubeSats are deployed, I think a stats summary of history is necessary. Something like:

Year	Successful deploy	Launch failure
2003	5
2004
2005	3
2006		14
2007	7
2008	10	2
2009
2010	8
2011		3
2012	16
2013	4

A bar graph may be better. --Fukumoto (talk) 14:43, 25 April 2013 (UTC)

More sats is space danger?

I'm a newbie so I'll be quick: does more satellites mean more potentially stray objects (and not small in this case) in space which contributes to space pollution and risk? I watched Gravity too. Because the CubeSat project means a massive increase in # of satellites over time, should we mention / link to this topic? Philou123 —Preceding undated comment added 22:58, 21 November 2013 (UTC)

• To quote Douglas Adams, Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. A few extra small satellites in fairly low (reasonably quickly decaying) orbits won't really make much difference. Of the top of my head there has only been once collision between two known and tracked objects that were not attempting rendezvous. The problem is thousands of tiny pieces of debris - mostly from exploded rocket stages, China's ASAT test and the aforementioned collision; not a couple hundred short-lived small satellites. --W. D. Graham 23:05, 21 November 2013 (UTC)

• But are they too small to track ? If so, that could make them dangerous. StuRat (talk) 17:23, 28 January 2015 (UTC)

• They are not. https://www.nasa.gov/mission_pages/station/news/orbital_debris.html : "DoD’s Space Surveillance Network tracks discrete objects as small as 2 inches (5 centimeters) in diameter in low Earth orbit" among other trackers. So they are both low in number (relative to what's causing the problem) and tracked.Winged Cat (talk) 03:42, 16 June 2017 (UTC)

Propulsion article

I think that the editors of this Wikipedia article may be interested in including this recent report on CubeSat propulsion: Green CubeSat Propulsion. by Jeff Foust. Monday, May 5, 2014 http://www.thespacereview.com/article/2506/1

Cheers, BatteryIncluded (talk) 15:43, 6 May 2014 (UTC)

"Notable past missions" section

I will be shortening or condensing the very long and messy "Notable past missions" section, as it is supposed to be a short summary or highlights of the main "parent" article List of CubeSats. If you feel a particular CubeSat should be mentioned in that summary section after I am finished, please feel free to add it. Cheers, BatteryIncluded (talk) 15:31, 22 May 2015 (UTC)

WP Spaceflight assessment

Expand bare url citations.

Take care of citations with errors in the templates.

Needs citations throughout. There needs to be no uncited paragraphs.

There are multiple areas where the most recent data is from 2012, that needs to be updated.

Be clear on what 1U of measurement is. Maybe even dedicate a section to it.

Reword these sentences:

The goal was to enable graduate students to be able to design, build, test and operate in space a spacecraft with capabilities similar to that of the first spacecraft, Sputnik.

The first CubeSats were launched in June 2003 on a RussianEurockot, and approximately 75 CubeSats had been placed into orbit by 2012.[9] (have been?)

The need for such a small-factor satellite became apparent in 1998 as a result of work done at Stanford University's Space System Development Laboratory.

The CubeSat specification accomplishes several high-level goals. The main reason for miniaturizing satellites is to reduce the cost of deployment and are often suitable for launch in multiples, using the excess capacity of larger launch vehicles.

Let me know when all of this is completed, and I will take another run at it. This article is very good overall and close to being assessed to a higher level. Kees08 (talk) 20:01, 4 December 2016 (UTC)

Pointer to a nanosat database

Wikipedians,

Should we add a pointer to a large database listing over 2000 nano/cube sats? I think this would help people find cubesats of interest, since it is searchable in many ways. It is listed here: http://www.nanosats.eu Geog4093 (talk) 02:54, 13 February 2018 (UTC)

I do not have an issue with that. Kees08 (Talk) 03:05, 13 February 2018 (UTC)

Great, I will add this tomorrow in class during a demo. John.adler (talk) 03:13, 13 February 2018 (UTC)

CubesSat size

This article says, that the size of a 1u-CubeSat is 100mm*100mm*100mm. But reference 2 says 100*100*113,5mm (page 22). Could soeone please change it? — Preceding unsigned comment added by Mark Fe (talk • contribs) 09:29, 20 January 2019 (UTC)

List of transceivers for CubeSats

Hello, Wikipedians!

How do you think is it useful to create table of CubeSat transmitters with their characteristics and keep it up-to-date after?

Something like this: Survey of modulation and coding schemes for application in CubeSat systems, but with addition of transmitter power, sensitivity etc. The reference belongs to my pet-project, however I guess to make it more flexible is the best way.

I believe this table can be included into Telecommunications paragraph and may be fruitful for researches.

I will appreciate your comments! Kirlf (talk) 15:32, 6 September 2020 (UTC)

It will most likely fail WP:GNG. It’s gonna be hard to keep a table on such a specific topic up to date, verifiable and exhaustive. Idell (talk) 19:13, 6 September 2020 (UTC)

It seems a little off-mission for an encyclopedia. This article should be a place for laymen to learn what a CubeSat is, not a parts catalog to help an engineer design a CubeSat. - MrOllie (talk) 19:41, 6 September 2020 (UTC)
