How to Cite NASA Website MLA: Your Definitive Guide
When you're working on a research paper, essay, or any academic project that requires you to draw information from NASA's vast online resources, knowing how to properly cite these sources is crucial. The Modern Language Association (MLA) style is widely used in the humanities, and it has specific guidelines for citing online materials, including those from government agencies like NASA. This guide will walk you through the process step-by-step, ensuring your citations are accurate and adhere to MLA standards.
Understanding the Core MLA Citation Elements for Websites
The MLA 9th Edition (the most current) emphasizes a container system for citations. This means you identify the source you're citing (the "item") and the larger whole it belongs to (the "container"). For a NASA website, the item is the specific page or article you're referencing, and the container is typically the NASA website itself.
Here are the essential components you'll need for most MLA website citations:
- Author(s): If an author is clearly identified, list them. Often, for government websites, there might not be an individual author, in which case you'll use the organization as the author.
- Title of Source: This is the title of the specific page, article, or document you are quoting or referencing.
- Title of Container: This is the larger work in which the source is found. For NASA websites, this will be the name of the NASA website itself (e.g., "NASA," "NASA Science").
- Publisher: This is the entity responsible for publishing the work. For NASA websites, this is usually "National Aeronautics and Space Administration" or simply "NASA."
- Publication Date: The date the source was published or last updated.
- Location: This is the URL (web address) where you found the information.
- Date of Access: The date you accessed the website. This is important because web content can change.
Citing a Specific Page or Article on the NASA Website
This is the most common scenario when citing NASA. You've found a fascinating article about a new mission, a stunning image with a description, or a detailed scientific explanation. Here's how to construct the citation:
General Format:
Author Last Name, First Name (if available). "Title of Specific Page or Article." Title of Container (Website Name), Publisher, Publication Date, URL. Accessed Date.
Example:
Johnson, Emily. "NASA's Perseverance Rover Lands on Mars." NASA Science, National Aeronautics and Space Administration, 18 Feb. 2021, science.nasa.gov/missions/perseverance/nasa-s-perseverance-rover-lands-on-mars/. Accessed 26 Oct. 2026.
Important Notes for this scenario:
- No Individual Author: If no individual author is listed for the specific page or article, you will start with the title of the source, as the organization (NASA) will be listed later as the publisher.
- Title of Container: Be consistent with the name of the NASA website. Often, it's simply "NASA" or a specific section like "NASA Science." Look at the website's branding to determine the most appropriate name.
- Publisher: While the website name might be "NASA," the formal publisher is typically the "National Aeronautics and Space Administration."
- Publication Date: Look for a "Published," "Updated," or copyright date. If only a year is available, use that. If no date is present, you can omit it, but it's highly recommended to find one.
- URL: Provide the full URL, including "http://" or "https://". MLA prefers that you omit "http://" or "https://" if the URL begins with "www."
- Date of Access: This is crucial. Format it as Day Month Year (e.g., 26 Oct. 2026).
Citing a NASA Image or Video
NASA's image and video galleries are incredible resources. Citing them requires a slightly different approach to capture the necessary details.
General Format for an Image:
Author/Creator (if applicable). "Title of Image." Name of Website/Gallery, Publisher, Date of Publication/Upload, URL. Accessed Date.
Example:
Hubble Space Telescope. "Pillars of Creation." NASA Image and Video Library, National Aeronautics and Space Administration, 1 Jan. 2002, images.nasa.gov/details/PIA03633. Accessed 26 Oct. 2026.
General Format for a Video:
Author/Creator (if applicable). "Title of Video." Name of Website/Platform, Publisher, Date of Publication/Upload, URL. Accessed Date.
Example:
NASA. "NASA's Mars Exploration Program: Perseverance Rover." NASA YouTube Channel, National Aeronautics and Space Administration, 10 Feb. 2021, www.youtube.com/watch?v=t3-27r2aIqE. Accessed 26 Oct. 2026.
Important Notes for Images and Videos:
- Author/Creator: For many NASA images, the creator might be a specific telescope (like Hubble) or a mission. If no specific creator is obvious, you may use NASA as the author.
- Title: The title of the image or video is usually clearly stated.
- Name of Website/Platform: This could be "NASA Image and Video Library," "NASA YouTube Channel," or similar.
- Publisher: Again, typically "National Aeronautics and Space Administration."
- Date: Look for the upload or publication date.
Citing a NASA Press Release
Press releases from NASA often contain important announcements and official statements.
General Format:
Author Last Name, First Name (if available). "Title of Press Release." NASA Press Releases, Publisher, Date of Release, URL. Accessed Date.
Example:
Smith, John. "NASA Announces New Lunar Mission." NASA Press Releases, National Aeronautics and Space Administration, 15 Mar. 2026, www.nasa.gov/press-release/nasa-announces-new-lunar-mission-date. Accessed 26 Oct. 2026.
Important Notes for Press Releases:
- "NASA Press Releases" as Container: You can use "NASA Press Releases" or a similar descriptive phrase as the title of the container if there isn't a specific overarching section name.
- Date of Release: This is usually prominently displayed on the press release.
Creating Your Works Cited Page
Remember that each citation you create in your text (using parenthetical citations) needs a corresponding entry on your Works Cited page. The Works Cited page is a separate page at the end of your paper that lists all the sources you have cited. It should be titled "Works Cited" and alphabetized by the first word of each entry (usually the author's last name or the title if no author is given).
Example Works Cited Page Snippet:
Hubble Space Telescope. "Pillars of Creation." NASA Image and Video Library, National Aeronautics and Space Administration, 1 Jan. 2002, images.nasa.gov/details/PIA03633. Accessed 26 Oct. 2026.
Johnson, Emily. "NASA's Perseverance Rover Lands on Mars." NASA Science, National Aeronautics and Space Administration, 18 Feb. 2021, science.nasa.gov/missions/perseverance/nasa-s-perseverance-rover-lands-on-mars/. Accessed 26 Oct. 2026.
Smith, John. "NASA Announces New Lunar Mission." NASA Press Releases, National Aeronautics and Space Administration, 15 Mar. 2026, www.nasa.gov/press-release/nasa-announces-new-lunar-mission-date. Accessed 26 Oct. 2026.
In-Text Citations
When you directly quote or paraphrase information from a NASA website in your paper, you must include an in-text citation. MLA generally uses the author's last name and the page number. However, for websites, page numbers are often not available.
General Format:
(Author Last Name)
or
(Title of Source if no author)
Examples:
According to NASA, the Mars Perseverance rover successfully landed on the Red Planet on February 18, 2021 (Johnson).
The iconic "Pillars of Creation" image, first captured by the Hubble Space Telescope, continues to inspire awe ("Pillars of Creation").
Important Notes for In-Text Citations:
- If you mention the author's name in your sentence, you don't need to repeat it in the parenthetical citation.
- If there is no author, use the first word or two of the title of the source (e.g., "Pillars"). Enclose titles of articles and web pages in quotation marks.
Frequently Asked Questions (FAQ) about Citing NASA Websites in MLA
How do I cite a NASA webpage if there's no author listed?
If no individual author is provided for a specific page or article on the NASA website, you will omit the author element and begin your citation with the title of the source in quotation marks. The organization, NASA (or National Aeronautics and Space Administration), will be listed as the publisher later in the citation.
Why is the "Date of Access" important for citing NASA websites?
The "Date of Access" is crucial for online sources because web content can be updated, edited, or even removed without notice. Including the date you viewed the material helps your reader understand that the information was current at the time you accessed it, and it provides a record if the content changes later.
What if the NASA website doesn't have a clear publication date?
If you cannot find a publication or update date for a NASA webpage, you can omit the publication date from your citation. However, it's always best practice to thoroughly search for a date, as it adds valuable context to your citation. Look for copyright dates at the bottom of the page or for update notices.
How do I cite a NASA video from YouTube?
When citing a NASA video from YouTube, treat YouTube as the container. The general format would be: Author (often NASA), "Title of Video," YouTube, Publisher (National Aeronautics and Space Administration), Upload Date, URL. Accessed Date. For example: NASA. "NASA's Mars Exploration Program: Perseverance Rover." YouTube, National Aeronautics and Space Administration, 10 Feb. 2021, www.youtube.com/watch?v=t3-27r2aIqE. Accessed 26 Oct. 2026.
By following these guidelines, you can confidently and accurately cite your sources from the NASA website, enhancing the credibility and academic rigor of your work.
