The Hubble Space Telescope, a large optical instrument having an aperture of 2.4 meters and a length of 8.8 meters has been developed by the U.S. National Aeronautics and Space Administration in cooperation with the European Space Agency. The Space Shuttle will be used to place the telescope in orbit. The primary astrometric instrument will be one of the three Fine Guidance Sensors which have the capability of measuring the position of one object with respect to another to an accuracy of ±0.″002. To facilitate use of the Hubble Space Telescope, observers will be provided with the Astrometric Data Reduction Software package. The variety of astrometric problems and the several modes of operation are mentioned as well as the cooperative program with the European astrometric satellite project HIPPARCOS.

The Space Telescope (ST) is one of the most exciting projects presently planned in space astronomy. It will make a considerable contribution to astronomical research throughout the rest of this century. The high resolution 2.4 m telescope will be placed in orbit probably in 1985 by the Space Shuttle and will provide an astronomical capability unattainable by the ground-based telescopes.The European Space Agency decided to participate in this NASA programme in 1976. ESA’s part in the programme includes the production of a major subsystem (the solar arrays and associated mechanisms), the building of the Faint Object Camera, and future participation in the operational activities and in the running of the Space Telescope Science Institute.

Abstract. Measurements of the spectrum of the atmospheric emission in the far-infrared (FIR) range, between 100 and 667 cm−1 (100–15 µm) are scarce because of the detection complexity and of the strong absorption of air at ground level preventing the sounding of the FIR from low altitude. Consequently, FIR measurements need to be made from high-altitude sites or on board airborne platforms or satellites. This paper describes the dataset of FIR spectral radiances of the atmosphere and snow surface emission measured in the 100–1000 cm−1 range by the Far-Infrared Radiation Mobile Observation System (FIRMOS) instrument during a 2-month campaign carried out from the ground at about 3000 m of altitude on the top of Mt. Zugspitze in the German Alps in 2018–2019. This campaign is part of the preparatory activity of a new space FIR mission, named Far-infrared Outgoing Radiation Understanding and Monitoring (FORUM), which is under development by the European Space Agency (ESA). The dataset acquired during the campaign also includes all the additional measurements needed to provide a full characterisation of the observed atmospheric state and the local atmospheric and surface conditions. It includes co-located spectral measurements in the infrared range from 400 to 1800 cm−1; lidar backscatter profiles; radio soundings of temperature, humidity and aerosol backscatter profiles; local weather parameters; and snow/ice microphysical properties. These measurements provide a unique dataset that can be used to perform radiative closure experiments to improve modelling parameters in the FIR that are not well-characterised, such as water vapour spectroscopy, scattering properties of cirrus clouds, and the FIR emissivity of the surface covered by snow.

Abstract:The HIPPARCOS Satellite, to be launched by the European Space Agency, will provide a stellar reference frame over the whole celestial sphere with an average accuracy of ± 0002 in each coordinate and component of annual proper motion, for some 100,000 stars.The origin of coordinates will be arbitrary. Absolute rotation of the system of proper motions can be obtained by measuring quasars relative to stars in the HIPPARCOS catalogue, either with the NASA Space Telescope or by conventional ground based astrometric observations.

In 2020, the Astronomical Observatory celebrates its 175th anniversary. The first director of the observatory was a student of the founder of the Pulkovo Observatory, Academician V.Ya. Struve Vasily Fedorovich Fedorov. Under his leadership, a site for the observatory was selected, a project was developed (by architect V. Beretti), a main building was constructed, and basic observatory astronomical instruments were commissioned. He also prepared and taught basic astronomy and surveying courses for university students. After him at the university, the post of professor of astronomy and director of the Astronomical Observatory was occupied by well-known astronomers A.P. Shidlovsky, M.F. Handrikov, R.P. Vogel, S.D. Chornyi. The main area of scientific research since the foundation of the observatory until the 1940s was astrometry and theoretical astronomy. With the arrival at the University of Kiev in 1939, the already well-known astronomer S.K. Vsekhsviatsky, along with existing scientific trends, astrophysical studies began. He started studying the small bodies of the solar system, physics of the sun and solar activity, astrophysics at the University of Kiev. The most important scientific achievements of the astronomers of the university include the work of determining the orbits of celestial bodies, the meridian observations of stars to create and maintain the celestial coordinate system, numerous observations of solar eclipses, which created the concept of dynamic solar corona, observing comets and meteors, application of the general theory of relativity in astronomy, development of the theory of gravitational lensing, opening of comets and participation in the international scientific project of the European Space Agency “Rosetta” on the research of Comet Churyumov-Gerasimenko.

The ‘Far InfraRed and Submillimetre Telescope’ (FIRST) is the fourth cornerstone mission in the European Space Agency (ESA) science programme. It will perform imaging photometry and spectroscopy in the far infrared and submillimetre part of the spectrum, covering approximately the 60–670 μm range.The key science objectives emphasize current questions connected to the formation of galaxies and stars, however, having unique capabilities in several ways.FIRST, a facility available to the entire astronomical community, will carry a 3.5 metre diameter passively cooled telescope. The science pay-load complement – two cameras/medium resolution spectrometers (PACS and SPIRE), and a very high resolution heterodyne spectrometer (HIFI) – will be housed in a superfluid helium cryostat.In early 2007, FIRST will be placed in a transfer trajectory towards its operational orbit around the Earth-Sun L2 point by an Ariane 5 (shared with the ESA cosmic background mapping mission, Planck). Once operational, FIRST will offer a minimum of 3 years of routine observations; roughly 2/3 of the available observing time is open to the general astronomical community through a standard competitive proposal procedure.

Abstract The James Webb Space Telescope (JWST) is frequently referred to as the follow-on mission to the Hubble Space Telescope (HST). The ‘Webb’ will be the biggest space telescope ever built and is expected to enable astounding new science. The observatory comprises a 6.5-m-diameter telescope with a segmented primary mirror and four high-performance optical science instruments. The JWST has mostly been optimized to work in the near- (0.6–5.0 μm) and mid-infrared (5.0–29 μm) wavelength regions. The project is a strong international partnership led by the National Aeronautics and Space Administration (NASA) with contributions from the European Space Agency (ESA) and the Canadian Space Agency (CSA). The observatory is currently scheduled for launch in early 2021 from Kourou, French Guyana, by an ESA-provided Ariane 5 rocket. This paper will focus on the European optical contribution to the mission, which mainly consists of two highly advanced optical science instruments: The multi-object near-infrared spectrograph (NIRSpec) and the mid-infrared instrument (MIRI). The opto-mechanical design considerations and the realization of both instruments will be described, and we will conclude with a short JWST project status report and future outlook.

AbstractThe Herschel Space Observatory was the fourth cornerstone mission in the European Space Agency (ESA) science programme with excellent broad band imaging capabilities in the sub-mm and far-infrared part of the spectrum. Although the spacecraft finished its observations in 2013, it left a large legacy dataset that is far from having been fully scrutinised and still has a large potential for new scientific discoveries. This is specifically true for the photometric observations of the PACS and SPIRE instruments. Some source catalogues have already been produced by individual observing programs, but there are many observations that risk to remain unexplored. To maximise the science return of the SPIRE and PACS data sets, we are in the process of building the Herschel Point Source Catalogue (HPSC) from all primary and parallel mode observations. Our homogeneous source extraction enables a systematic and unbiased comparison of sensitivity across the different Herschel fields that single programs will generally not be able to provide. The catalogue will be made available online through archives like the Herschel Science Archive (HSA), the Infrared Science Archive (IRSA), and the Strasbourg Astronomical Data Center (CDS).
