Questions about the nasa.gov favicon

Where is the nasa.gov favicon?

The main one is at https://www.nasa.gov/wp-content/plugins/nasa-hds-core-setup/assets/favicons/favicon-32x32.png. The default path, https://www.nasa.gov/favicon.ico, also returns an icon.

What size is the nasa.gov favicon?

favicon-32x32.png is 32×32. The largest raster icon on the site is android-chrome-512x512.png at 512×512 px.

Can Google Search show the nasa.gov favicon?

The site meets Google's rules: apple-touch-icon-180x180.png is a 180×180 PNG file (17.1 KB) and robots.txt allows it. Google still decides what it shows.

Does nasa.gov have an Apple touch icon and a maskable icon?

The Apple touch icon is 180×180, with transparent areas that iOS turns black. The manifest has no maskable icon, so Android shrinks the regular one onto a white circle.
