The �ve orbiters travelled a combined distance of
513 million miles. That’s 1.3 times the distance
from the Earth to Jupiter.
When in orbit around the Earth, the crew experienced
a sunrise or sunset every 45 minutes.
The SRBs were jettisoned two minutes into the �ight,
at an altitude of 44 km. Their momentum carried them up to 65 km before they fell back to Earth.
Columbia makes its �rst orbital �ight
The onboard �ight computer ran on only 1 MB of RAMabout a hundredth of that of
a Nintendo Wii.
The orbiter was made up of more than 2.5
million components, including over 200
miles of wire.
By the time it reached an altitude of 235 miles, the orbiter would be
travelling at a speed of 17,500 mph, covering the length of 75
football pitches every second!
There were about 25,000 heat-resistant tiles on the
orbiter, which had to withstand a temperature range of almost 1800 °C.

The orbiter’s three main englines ran on liquid hydrogen and oxygen, generating a total of 37 million horsepower.
There were two smaller engines for manoeuvring and making orbital adjustments.
A 15-metre mechanical arm was used to deploy and
retrieve satellites and other equipment.
Each shuttle launch cost NASA $450
million. The total cost of the program was about $200 billion.
Fully-fuelled, the shuttle weighed 2000 tonnes. Two-thirds of the thrust needed for
lift-o� was provided by the solid rocket
boosters (SRBs). The orbiter’s main engines
provided the remainder.
The shuttle’s external fuel tank separated from the
orbiter nine minutes into the �ight, and would burn up in
the Earth’s atmosphere.

Touching the SkyA tribute to the space shuttleOn the morning of 8 July 2011, more than a million people gathered at Cape Canaveral, Florida to see the final launch of the space shuttle program. With the help of two giant solid rocket boosters, each providing several million pounds of thrust, the orbiter Atlantis lifted slowly off the launchpad for the last time. Used to carry large payloads into orbit, the shuttle was NASA’s workhorse for 30 years. Both the orbiter and rocket boosters were designed to be used repeatedly, making the shuttle the world’s first reusable spacecraft. But in the face of rising costs, and after 135 missions and the Challenger and Columbia disasters, NASA has finally retired the ageing space shuttle. Join us as we explore the machine that helped to construct the International Space Station (ISS), put the Hubble Telescope into orbit and inspired a generation to dream of space.
