This has nothing to do with Hubble's first months.
The article describes how the mirrors are deliberately misshapen at normal Earth temperatures, so when they cool down to their -380F/-230C/44K operating temperature they will then (hopefully!) be in focus.
I did not know that before; I learned about it and a few other interesting facts from this article.
Clickbaity title or not, I found it an informative read.
- Tagbert 5y agoThe headline is definitely playing off of fears of a repeat of the Hubble error.

- smegsicle 5y agoidk i hear space crap is kind of a big deal there? not to mention most readers who care at all about this new telescope probably have indeed read about the old one..
- wolverine876 5y agoGood points, though I won't take them that far. To be aware of the Hubble's issues at the time, you'd need to be at least ~40 years old now.
