Spacelab and 30 years of ESA astronauts
Thirty years ago this week the first European-built Spacelab was launched on the Space Shuttle. ESA’s first astronaut, Ulf Merbold, flew on the mission, marking ESA’s entry into human spaceflight.
On 28 November 1983 at 11:00 local time, the ninth Space Shuttle mission was launched from Kennedy Space Center, Florida, USA.
The six astronauts on Spacelab-1 worked in two teams on 12-hour shifts, allowing for continuous operations. They performed over 70 experiments in solar physics, space plasma physics, astronomy, Earth observation, material science, technology and life sciences.
After circling Earth 166 times in just over 10 days, Space Shuttle Columbia landed back on Earth on 8 December.
Spacelab was a cooperation between ESA and NASA, with Europe responsible for funding, designing and building Spacelab and agreeing to deliver free of charge the engineering model, the first flight unit and ground equipment in return for a shared first mission.
In preparation for Spacelab, ESA Member States in 1978 put forward 53 astronaut candidates, and four were selected: Ulf Merbold of Germany, Wubbo Ockels of the Netherlands, Claude Nicollier of Switzerland and Franco Malerba of Italy.
Ulf was selected for the first Spacelab mission, with Wubbo as backup. Wubbo flew on the Spacelab-D1 mission in 1985.
Between 1983 and 1998, Spacelab modules flew on the Space Shuttle 22 times and totalled 244 days in orbit. Experiments surveyed the possibilities of weightless research in many scientific areas that led to space-age metals used in mass-produced smartphones and revealed areas of space research that show promise in treating chronic muscle diseases.
Many of Spacelab’s features live on in space hardware that is flying above us today. The pressure shell was reused for the Harmony and Tranquility modules on the International Space Station, and supply spacecraft, such as ESA’s Automated Transfer Vehicles and the commercial Cygnus, reuse Spacelab’s exterior structure.
Europe’s Columbus laboratory on the Station evolved from Spacelab. On the inside, Spacelab used standardised science racks that contributed to its success and were adopted for all of the Station’s laboratory modules.
In the same way that Spacelab was operated by international teams of astronauts, so are today’s European experiments and laboratories on the Station. They are kept running and performing science by the Station’s permanent crew – which now includes European astronauts.
