In 1988 the planetarium was the largest school astronomical facility in the GDR.

The space flight planetarium "Sigmund Jähn" on the Peißnitzinsel in Halle (Saale) was a middle planetarium with 130 seats. The client was the city of Halle and it was opened on November 10, 1978 after a two-year construction phase. The planetarium was named in honor of Sigmund Jähn , the first German cosmonaut .

Spacemaster DP2 was used as a planetarium projector by the Carl Zeiss works in Jena, and it was the first of its kind to be controlled manually and fully automatically. The planetarium also had an observatory equipped with a Coudé refractor .

In November 2014 the city council of Halle decided to demolish the planetarium and build a new one in the old gasometer at the Holzplatz. Initially the demolition of the listed planetarium was planned for 2017, the demolition work finally began in 2018.

According to the representation of the city council factions in spring 2018, the demolition was based only on a misunderstanding. The State Administration Office (LVwA) said it had not requested a demolition. Several initiatives to save the building complex, including the Peißnitzhaus association and the “Shell Dome” initiative, were thus passed over.

At the beginning of the 1970s, Carl-Zeiss-Werke Jena presented a planetarium projector that was the first of its kind to be controlled manually and fully automatically. They were looking for a planetarium as a reference object for export customers, as close as possible to the Leipzig trade fair, for which the then mayor of the nearby city of Halle, Hans Pflüger, advocated and was awarded the contract. The building was designed by the architect Klaus Dietrich together with the architect and civil engineer Herbert Müller . In 1976 the two-year construction of the planetarium on the Peißnitzinsel began . Müller used the component he developed, a long and only slightly curved half-tube, the HP shell . He used it to build the actual round building from just five different types of shells, each with 28 pieces. The planetarium was unique in this form to this day. It was opened with a celebration on November 10, 1978.

Because of its location on the Peißnitz Island , the planetarium was damaged several times by floods in the Saale . After the flood in 2013 , which also damaged the projector, the city of Halle, as the owner , decided to give up the location and build a new planetarium elsewhere. In November 2014 the city council of Halle decided to demolish the planetarium and build a new one in the old gasometer at the Holzplatz. The decision to demolish was controversial because of the architectural features of the old planetarium.

The decision in favor of the new location was also criticized, as it is an old industrial area whose soil is contaminated with pollutants. In addition, the construction costs of 8 million euros exceed the funding from the flood relief fund of 6.8 million euros. However, funding for a new planetarium was only available when the old building was demolished. The former spaceflight planetarium has been a listed building since June 2015. This protection was lifted a year later by the monument authority in favor of the new building on the wood yard.

Replacement new gasometer lumber yard

The new planetarium will be built at the Holzplatz on the Saline Island between the old town and the new town within the listed brick facade of the gasometer , which was completed in 1891 and closed in 1972. The Saline Island was already one of seven locations in the focus of the IBA Urban Redevelopment 2010 , when a culture gasometer with a new glass dome was planned. The site of the former gas works had already been redeveloped from 2004 to 2005 with regard to the contaminated sites. After the flood in 2013 and the damage to the space flight planetarium, a year later there was a design with a domed hall on top of the gasometer for a large event and exhibition room. The observatory with the telescope should be built on the elevator tower next to the gasometer. For this, 6.8 million euros from the flood aid fund of the federal and state governments were planned, the additional costs of 1.2 million euros were to be financed from other sources. Eight other locations have also been examined for a replacement building, but the city administration expects the gasometer to revitalize the wood yard in the immediate vicinity of the city center and stimulate development for the area, in particular for the Glaucha district . In autumn 2015, the project planning for the new planetarium was put out to tender. The contract was awarded to the Leipzig branch of the architectural office RKW Architektur + .

On June 2, 2016, almost 14.2 million euros from the flood aid fund were approved as 100 percent funding for the replacement of the planetarium, after which construction should take place from August 2017 to June 2019. At the meeting of the culture committee on September 7, 2016, the city administration stated on request that the concept created in 2014 was only a very rough preliminary planning for the funding application . The new concept is more concrete, u. a. coordinated with the monument protection . The modern technical equipment alone is almost 2.5 million euros more expensive than planned in the preliminary planning.

The new concept provides for the planetarium in the gasometer to be built on a floor slab so that the ground floor is 81 cm above the highest high water line HQ 100 . The listed brick facade is being renovated and repaired. The name RAUMFLUG PLANETARIUM will be dismantled from the old planetarium and attached above the main entrance area. Floor-to-ceiling glazing will allow the interior facade of the gasometer envelope, which is also listed, to be experienced from the foyer and the stairs. The steel parts of the industrial architecture that still exist remain as visible evidence of the historical gasometer.

The building will have a total net floor space of 944.74 m². The dome room, entrance and foyer area with cash register, cloakroom, exhibition and shop, cafeteria with catering kitchen, technical rooms and sanitary rooms are planned on the ground floor. In the exhibition area, u. a. the no longer functional projector from the old planetarium can be seen. The dome will be twelve meters in diameter. The dome room will be equipped with 110 chairs that will be easy to dismantle. This makes it possible to hold other events, events or shows.

The upper floor and the observation platform are accessed via two internal stairs. A lecture room for approx. 80 people, a classroom for 29 people, the library with computer workstations, offices with a meeting room and the necessary sanitary rooms are planned on the upper floor. Mobile telescopes, for example, can be set up on the observation terrace to observe the starry sky. A tour on the roof will allow a view of the city from an elevated perspective. The observatory is planned to be above the level of the observation terrace.

In contrast to the other areas, the telescope of the observatory is not barrier-free due to its construction . In order to enable people with disabilities to directly observe the stars, the transmission of the telescope image into the dome with a so-called digital interface is planned. A Zeiss ZKP4 star projector in conjunction with Zeiss “Velvet” projectors is planned for the planetarium . The so-called “Powerdome library” contains a. almost all digital and virtual representations of the planetary system in the old planetarium. The software contained in the new system and the integrated digital image library make it possible to acquire new digital and virtual representations on a purchase / rental basis or to produce your own presentations. A "KVM Matrix System" connects the dome, the production studio and the observatory with the associated technology, so that central or decentralized operation is possible.

The city of Halle (Saale) is the owner of the entire Holzplatz area. The 28 car parking spaces, two disabled parking spaces and two bus parking spaces required to operate the planetarium will be built on the urban site south of the gasometer. There are also 32 bicycle parking spaces on the east side of the gasometer.

In July 2017 it became known that the start of construction had to be postponed to spring 2018 due to the ongoing structural examination. The groundbreaking ceremony was on January 21, 2019. The opening of the planetarium is scheduled for 2021.
