Welcome
WELCOME TO
THE OFFICIAL
PI MAGAZINE!
I
n December last year, British Army
Air Corps officer Timothy Nigel Peake
stepped aboard the Soyuz TMA-19M
to start a six-month mission aboard the
International Space Station. It was a small step
across the ISS hatch for Tim, but as the first
British European Space Agency astronaut it
was a giant leap for the United Kingdom and
especially the children that dream of one day
going to space.
Tim wasn’t the only UK-born passenger aboard
the ISS, though; two Raspberry Pis joined him on
his mission to carry out experiments developed
by British schoolchildren. While Tim returned
to Earth on 18 June, our two intrepid Raspberry
Pis, Ed and Izzy, remain aboard to continue their
ongoing mission to inspire and educate children
all over the world via the Astro Pi programme.
You can learn all about Astro Pi in our massive
cover feature starting on page 14, and how Astro
Pi and other educational programmes Tim has
been involved with have touched the lives of and
inspired more than a million schoolchildren.
Enjoy the issue!
