Submit your add-ons in this issue, thanks for your contribution! Submission template:

**Title:**
**Description:** (a short description to be shown on the addon download window)
**Proposed category:** (pick one of the existing categories (https://celestia.mobi/resources/), or suggest a new one)
**Demo Object Name:** (optional, the name of the main object used for Go to command)
**Author(s):**
**Release date:** (The date this add-on is released. If left empty, will be the date the add-on is uploaded here)
**Link to download:** (Please use zip to package the add-on, it should contain a file called description.json)
**Image:** (optional, no UI control element, HUD display, label. Avoid using "tall" pictures (height > width))
**Thumbnail:** (optional, by default will be the downscaled version of Image if present, so unless you want something different to show as a thumbnail, leave it empty)
**Additional metadata:** (optional, this can be anything that web supports. Link, image, audio, video, text, attributed text, cel URL, cel/celx scripts, embedded stuff (for example a YouTube video)...)

For updates to existing add-ons, please attach the id to the add-on and only include updated fields from the template. For removal of add-ons, please attach the id too.

The id is part of the link to the add-on: For example, this addon below has an id of A4577B17-4C60-0C1E-CAB5-92A604FF0EC3 https://celestia.mobi/resources/item?item=A4577B17-4C60-0C1E-CAB5-92A604FF0EC3

Check before uploading an add-on

Your add-on will be running on Android/iOS/macOS/Windows, to enable maximum compatibility, please ensure that

1. files names referenced in models, ssc, dsc files, etc are exactly the same as the actual file names (some file systems are case sensitive. For example if in your .ssc there is Mesh "Progress.cmod", then the file name should be exactly Progress.cmod not progress.cmod).
2. Textures should have width/height of power of 2 (for example: 1024 512, a texture of 1000 500 will not work on many mobile devices).
3. If your add-on requires specific Celestia versions, please mention in the description. Please also ensure that your add-on should not crash running on other versions.
4. If you are updating an existing add-on, note that existing users will not see an update button, so it might be a good idea to include version history in the description.
5. Please try to use smaller files for image/thumbnail/other metadata. For example, use JPG if alpha value is not needed.

Example:

Title: Kepler-1649 Description: The Kepler-1649 planetary system, which is a red dwarf star orbited by a Venus-analogue and an Earth-analogue. Alternate surfaces for planet c are included.

Title: 2020 SO Description: 2020 SO is a near-Earth object that was discovered on September 17, 2020. Previously thought to be an asteroid, but later found to be the booster rocket stage of the Surveyor 2 space probe launched to the Moon in September 1966.

@levinli303 What do you think about creating a category called "Space debris", because like the addon I posted here, in this case the 2020 OS is a space debris. What's more, there are a few more space debris addons I'd like to put here soon, and I wouldn't consider them "spacecrafts".

[levinli303]

I'll leave it to @DaveBowman2001 to decide. and if we are to create a new category, we'll need a new for the category.

[DaveBowman2001]

Please don't add the Space Shuttles, Soviet Space Program, and Project Apollo yet to mobi...there are many features there that aren't suitable for mobile use yet. Also, spent rocket stages aren't that as interesting as the spacecrafts themselves, but if you want to add a category for space debris, go for it

[SpaceExplorer2008]

@DaveBowman2001 I think you're right about Space Shuttles. We will add them more in the future. I think it's interesting to also include space debris, but in a separate category from spacecrafts.

Title: HD 141569 Description: HD 141569 is a young A-type pre-main sequence star about 362.64 light-years away in the constellation Libra. In 1999, a protoplanetary disk was discovered around the star with a prominent gap between the inner and outer portions of it, leading to speculations that a possible planet was forming in it, though none was found orbiting the star Proposed category: Stars Demo Object Name: HD 141569 Author(s): Cham Release date: 2009-Aug-28 Link to download: HD 141569.zip Image:

Title: WASP-12 Description: WASP-12 Ab is a hot Jupiter discovered in 2008 orbiting the star WASP-12 A, 1410 light-years away from Earth in the constellation Auriga. Due to its close proximity to its parent star, WASP-12 Ab is estimated to have an oval shape due to the star's tidal forces. Proposed Category: Exoplanets (Early Years, 1988 - 2008) Demo Object Name: WASP-12 Ab Author(s): SevenSpheres Release date: 2019-10-11 Link to download: wasp-12.zip Image:

Title: Vega Description: Vega is a young A-type main-sequence star about 25 light-years away in the constellation Lyra. It is the fifth brightest star in the naked eye. In 1983, infrared analysis of the star determined that it contains a protoplanetary disk, one of the first stars detected to contain such structures, however it wasn't confirmed to exist until 2005. In addition, a planet was detected orbiting the star in 2021, but its existence is yet to be confirmed by follow-up studies Proposed category: Stars Demo Object Name: Vega Author(s): Cham Release date: 2009-Sept-17 Link to download: Vega.zip Image:

Update and Proposal to rename "Vostok 1" (F6E31C15-D5A5-D203-F272-9688AFE4C300) into "Vostok 1 to 6". Added the unmanned Korabl-Sputnik test flights and follow-up crewed missions Vostok 2 to 6

Title: Vostok 1 to 6 Description: The Vostok program was a Soviet human spaceflight project to put the first Soviet citizens into low Earth orbit and return them safely, directly competing with NASA's Project Mercury. It flew five unmanned test flights in 1960 under the codename Korabl-Sputnik, before culminating in the flight of Yuri Gagarin, the first human in space, in 1961-Apr-12. Five other Vostok missions were launched until 1963, when it was succeeded by the Voskhod and later Soyuz programmes

(NOTE: The model is a little heavy and therefore may cause some minor crashes)

Title: Genesis Description: Genesis was a NASA sample-return probe that collected a sample of solar wind particles and returned them to Earth for analysis. It was the first NASA sample-return mission to return material since the Apollo program, and the first to return material from beyond the orbit of the Moon. Genesis was launched on August 8, 2001, and the sample return capsule crash-landed in Utah on September 8, 2004, after a design flaw prevented the deployment of its drogue parachute. The crash contaminated many of the sample collectors. Although most were damaged, some of the collectors were successfully recovered.

Update to "Rosetta" (77DCDAB9-5C56-208C-ADAC-56F51AD6512F). Removed 21 Lutetia and 2867 Steins, and made them into two separate addons. Adjusted Philae's z-coordinates so that it touches the edge of the comet's CMOD model

Description: Rosetta was an ESA space probe launched on 2004-Mar-2. Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko until the latter crashed intentionally on the comet's nucleus on 2016-Sept-30.

@DaveBowman2001 I do not think we should post too many images/videos. Rosetta has 12 pics and 3 videos where a wikipedia link might work better.

[DaveBowman2001]

Should've compiled some photos into a single image. Will provide a metadata update for Rosetta later

@levinli303 it seems a comment section has been added to addon pages. This needs to be either moderated or removed to prevent the kind of inappropriate comments seen here.

[SpaceExplorer2008]

I would suggest that this function of adding comments in addons should be removed immediately, from what we realize it won't work to keep this.

[SevenSpheres]

Also, why are there two identical Chariklo addons?

[DaveBowman2001]

Also, why are there two identical Chariklo addons?

I confirm. Here's the duplicate entry (the one without a description)

ah trolls. removed the comment section for now. I'll maybe add a moderation queue in the future
