Aims. In this paper the calibration and in-orbit performance of Heterodyne Instrument for Far-Infrared (HIFI) is described.
Aims. The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter is a hard X-ray imaging spectrometer, which covers the energy range from 4 to 150 keV. STIX observes bremsstrahlung emissions solar flares and therefore provides diagnostics of hottest (⪆10 MK) flare plasma while quantifying location, spectrum, content flare-accelerated nonthermal electrons. Methods. To accomplish this, applies an indirect bigrid Fourier technique using set tungsten grids (at pitches 0.038 1 mm) in...
The X-ray Integral Field Unit (X-IFU) is the high resolution spectrometer of ESA Athena observatory. Over a field view 5' equivalent diameter, it will deliver spectra from 0.2 to 12 keV with spectral 2.5 eV up 7 on ∼ 5" pixels. X-IFU based large format array super-conducting molybdenum-gold Transition Edge Sensors cooled at 90 mK, each coupled an absorber made gold and bismuth pitch 249 μm. A cryogenic anti-coincidence detector located underneath prime TES enables non background be reduced....
BRITE-Constellation (where BRITE stands for BRIght Target Explorer) is an international nanosatellite mission to monitor photometrically, in two colours, the brightness and temperature variations of stars generally brighter than mag(V) ≈ 4 with precision time coverage not possible from ground. The current design consists six nanosats (hence Constellation): Austria, Canada, Poland. Each 7 kg nanosat carries optical telescope aperture 3 cm feeding uncooled CCD. One instrument each pair...
The Colour and Stereo Surface Imaging System (CaSSIS) is the main imaging system onboard European Space Agency's ExoMars Trace Gas Orbiter (TGO) which was launched on 14 March 2016. CaSSIS intended to acquire moderately high resolution (4.6 m/pixel) targeted images of Mars at a rate 10–20 per day from roughly circular orbit 400 km above surface. Each image can be acquired in up four colours stereo capability foreseen by use novel rotation mechanism. A typical product one acquisition will...
The X-ray Integral Field Unit (X-IFU) on board the Advanced Telescope for High-ENergy Astrophysics (Athena) will provide spatially resolved high-resolution spectroscopy from 0.2 to 12 keV, with 5 arc second pixels over a field of view minute equivalent diameter and spectral resolution 2.5 eV up 7 keV. In this paper, we first review core scientific objectives Athena, driving main performance parameters X-IFU, namely resolution, view, effective area, count rate capabilities, instrumental...
eXTP is a science mission designed to study the state of matter under extreme conditions density, gravity and magnetism. Primary goals are determination equation at supra-nuclear measurement QED effects in highly magnetized star, accretion strong-field regime gravity. targets include isolated binary neutron stars, strong magnetic field systems like magnetars, stellar-mass supermassive black holes. The carries unique unprecedented suite state-of-the-art scientific instruments enabling for...
BRITE (BRIght Target Explorer) Constellation, the first nanosatellite mission applied to astrophysical research, is a collaboration among Austria, Canada and Poland. The fleet of satellites (6 launched, 5 functioning) performs precise optical photometry brightest stars in night sky. A pioneering like - with optics instruments restricted small volume, mass power several nanosatellites, whose measurements must be coordinated orbit poses many unique challenges. We discuss technical issues,...
Context. The BRIght Target Explorer (BRITE) mission is a pioneering space project aimed at the long-term photometric monitoring of brightest stars in sky by means constellation nanosatellites. Its main advantage high accuracy and time coverage which are inaccessible from ground. drawback lack cooling CCD detectors absence good shielding that would protect them energetic particles.

The "sonic region" of the Sun corona remains extremely difficult to observe with spatial resolution and sensitivity sufficient understand fine scale phenomena that govern quiescent solar corona, as well lead coronal mass ejections (CMEs), which influence space weather. Improvement on this front requires eclipse-like conditions over long observation times. space-borne coronagraphs flown so far provided a continuous coverage external parts but their over-occulting system did not permit analyse...
The Spectrometer/Telescope for Imaging X-rays (STIX) is a remote sensing instrument on Solar Orbiter that observes the hard X-ray bremsstrahlung emission of solar flares. This paper describes STIX Aspect System (SAS), subunit measures pointing relative to Sun with precision $\pm 4''$ , which required accurately localize reconstructed images Sun. operating principle SAS based an optical lens onto plate perforated by small apertures arranged in cross-shaped configuration four radial arms....
The Modular X- and Gamma-ray Sensor (MXGS) is an imaging spectral instrument mounted on the starboard side of Columbus module International Space Station.
