Why are you so sad that NASA is protecting people from a Sith invasion?
They’re choosing to believe that the sample return tube is this sudden unexpected thing that had to be quickly explained. The rover was known to be designed to do this for years.
Early publications regarding Perseverance explain in high detail the sample tubes.
Published on December 22, 2020:
“Made chiefly of titanium, each sample tube weighs less than 2 ounces (57 grams). A white exterior coating guards against heating by the Sun potentially changing the chemical composition of the samples after Perseverance deposits the tubes on the surface of Mars. Laser-etched serial numbers on the exterior will help the team identify the tubes and their content.”
Ah, yes, now that there's a webpage on the Internet saying the same thing you've claimed, all doubt is out the window.
The contention in this particular instance is not on the tubes themselves but the claim that they are “ad-hoc”.
But of course. As is typical of RE'ers, an ad-hoc explanation must be presented.
Suggesting that it’s just a sudden ad-hoc explanation suggests that the tubes are an expected artifact of the images to be explained, when this isn’t the case. It was already known what they look like since 2020.
