Some former NASA astronauts
have a message for flat-Earther B.o.B: The curve is real, and we've seen it.
Last week, the Atlanta-based
rapper kicked off a crowdfunding campaign to raise $1 million, ostensibly so he
can build
and launch one or more satellites to settle the "question"
of Earth's shape once and for all.
B.o.B doubts that Earth is
round because the horizon looks pretty flat in photos taken from the planet's
surface. That's a simple consequence of Earth's large size, of course, but
B.o.B doesn't see it that way. "Help B.o.B find the curve!" the crowdfunding
project's description reads, in part.
This plea elicited a
response from former NASA astronaut Terry Virts.
"I can save BoB a lot
of money — the Earth is round. I flew around it," Virts tweeted Wednesday
(Sept. 27) via his @AstroTerry account.
Apollo 11 moonwalker Buzz Aldrin (@TheRealBuzz)
responded to Virts Wednesday, tweeting, "I did too. It's called an orbit:
the curved path of a celestial object around a star, planet, or moon."
Retired astronaut Scott
Kelly also chimed in Wednesday, posting a time-lapse video of our planet as
seen from the International Space Station.
"Show you the curve?
Here you go @bobatl! One full orbit around Earth. Maybe donate funds raised to
#PuertoRicoRelief," Kelly (@StationCDRKelly) tweeted.
B.o.B hasn't been swayed by
thousands of satellite
photos, the circumnavigation of the globe, common sense or any of the other
evidence showing beyond a shadow of a doubt that Earth is round, so Virts,
Aldrin and Kelly are probably just shouting into the wind. But hey, it's worth
a shot.
