Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content.

7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.

Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link.

Elon's daily dose. It takes a lot to get on his level.
Just kidding, but it seems like something to do with the fuel/exhaust.
I've read multiple articles and the most I've gotten is that their first launch didn't have the cleaner fuel that future launches did. I am not sure how that would cause repeated incidents... perhaps it's from metal parts in the rockets? 🤔 I could have missed something as I was reading but hopefully someone else will know the answer.
Cleaner fuel? It's oxygen and methane. Carbon, hydrogen, and oxygen, no mercury. Still I can't think of a source.
The article I read said they didn't use that until after the first launch. I did not look into it further.
I couldn't think of a source either. Upon closer inspection, it seems possible that this entire story is based on two typos in the Texas Commission on Environmental Quality report.
If that kind of shit gets released on the ground, what gets released into the upper atmosphere?
CO2 and water. The rocket fuel is not the source of the mercury.
The pumps need to be running full bore before ignition and keep running after cut off. Watch a video of shut off and tell me where they're keeping all that CO^2 and water on the rocket.
What?
At shut off and start up the rocket pumps methane and oxygen into the atmosphere before ignition. The Falcon 9 pumps kerosene and oxygen. Watch the live streams and look at the engines at meco.
