NASA’s Space Shuttle program will be retired later this year to make room for the next big thing, and it got me thinking about the fact that somebody’s eventually going to make the first Tumblr group blog in space. I just hope it’s for something relevant like videos of people experiencing weightlessness and not a bunch of cute photos of pandas, but either way… it’ll be huge.

Here are today’s Tumblr Tuesday picks:

Phone Funeral
A memorial for cellphones that met their doom in tragically violent accidents. In lieu of flowers, please send strong iPhone cases.

Fake Science
Finally, a place with straightforward and common-sense answers to all of the greatest mysteries of science!

Vintage Madison Ave.
I know these ads are vintage because everyone looks exactly the same and not a single model appears to be malnourished.

Big Damn Deal
A new twice-weekly webcomic about a San Francisco startup with an identity crisis.

Marina Abramović Made Me Cry
Performance artist Marina Abramović’s current exhibit at MoMA has her sitting in silence while museum guests sit across from her and stare. Some people couldn’t handle the heat.
