Hello, I'm Materialscientist. I noticed that you made a change to an article, SpaceX Raptor, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 10:20, 16 November 2020 (UTC)

Sorry for the way I am replying, I'm not that well indited in the wiki format... I found a citation, I'm not quite sure how to add it thou...

The source is two Elon Musk tweets from last year. I'll read the citation article, but how do I return it to the article? Should I copy-paste it or is there another process?
