In 1969, at the Presidium of the Bulgarian Academy of Sciences, the Research Group on Space Physics was established.
By a Resolution of the Board of the Council of Ministers of 3 March1975, this Group evolved into the Central Laboratory for Space Research (CLSR), which in 1987 was reorganized into the Space Research Institute at the BAS (SRI–BAS).
In October 1990, the Solar-Terrestrial Influences Laboratory at the BAS (STIL–BAS) was established. In 1996, the STIL–BAS evolved into Central Solar-Terrestrial Influences Laboratory at the BAS (CSTIL–BAS) with a branch in the Town of Stara Zagora, and in 2008 the CSTIL–BAS was reorganized into the Solar-Terrestrial Influences Institute at the BAS (STII–BAS).
Under the reform carried out at the Bulgarian Academy of Sciences, by a Resolution of the General Assembly of the BAS
of 23 March 2010, the Space Research Institute (SRI) and the Solar-Terrestrial Influences Institute (STII) merged to form a new unit – the Space and Solar-Terrestrial Research Institute at the BAS (SSTRI–BAS).
Now the Institute is renamed to Space Research and Technology Institute (SRTI).
