In 1977 Malerba was selected as one of four European Payload Specialist Candidates for the first Spacelab mission, in ESA’s first astronaut selection. On selection he joined the Space Science Department of ESTEC, in the Space Plasma Physics Division, working on the development, testing, and qualification of ES020 - PICPAB, an experiment in Ionospheric Plasma Physics for the first Spacelab payload, which was launched in 1983. He was subsequently selected in 1989 as a Payload Specialist by the Italian Space Agency (ASI) and NASA, and was assigned to the NASA Johnson Space Center, Houston, Texas, for training. In September 1991, he was designated Prime Payload Specialist for the TSS-1 Space Shuttle mission. Malerba flew as the first Italian in space on STS-46 in 1992.

• 1967–1978 - Worked in solid-state physics at the Max Planck Institute for Metals Research
• 1976 – Doctorate in Sciences from the University of Stuttgart
• 1977-1994 – Selected as ESA European Payload Specialist for the first Spacelab mission, ESA Astronaut on three missions from 1983 to 1994

In 1977, Merbold was selected as one of four European Payload Specialist Candidates for the first Spacelab mission, in ESA’s first astronaut selection. A year later he was nominated as one of the three Payload Specialists for the mission and in 1982 was selected for flight. Merbold was the first ESA astronaut to fly in space, and the first non-US citizen to fly on a Space Shuttle, as part of the crew of the STS-9 Spacelab 1 mission on Space Shuttle Columbia in 1983. The primary objective of this mission was the verification of Spacelab in orbit. Subsequently, he was ESA's Payload Specialist on STS-42 (1992), the International Microgravity Laboratory mission (IML-1) on the Space Shuttle, and was selected to fly with ESA's Euromir 94 mission (1994) to the Russian Space Station MIR. He was the first ESA astronaut to fly on a Russian mission. Among other responsibilities for ESA, he worked on the Columbus programme and served as head of the DLR’s astronaut office. He continued working for ESA until his retirement in 2004.

• Italian physicist and engineer, industrial experience with Fiat and Olivetti
• 1967-1973 - Director of ESOC

Montalenti joined ESRO in 1967 to become Director of ESOC (European Space Operations Centre) in Darmstadt, replacing Stig Comet. Reform of ESRO's administrative structure in 1967, meant that ESOC (formerly ESDAC) took over responsibility for operating satellites after their launch, work previously carried out by the flight control group at ESTEC in Noordwijk; Montalenti's challenge in 1967 was to integrate this group. His successful first launch, (ESRO 2 in March 1968) confirmed morale and Montalenti oversaw a further 300 sounding rocket launches from Kiruna as well as those of the satellites HEOS 1 and 2, TD 1 and ESRO 4.
