“…Achromatic jet-breaks have been observed in optical/IR, however they often do not coincide with breaks observed in X-rays, indicating that our knowledge of the afterglows emission is still limited, and questioning if the jet-angle and collimated energy that have been estimated are right. Even if from the theoretical side many explanations (energy injections, double jet, structured jets) have been proposed to interpret the afterglow emission from IR/optical to X-rays, more multi-frequency observations are necessary (see, e.g., Willingale & Mészáros, 2017). Compared to today, the larger number of THESEUS GRBs and the more sensitive spectra observed with XGIS will allow us to better understand the nature of the afterglow and of the central engine of GRBs.…”

THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. These goals will be achieved through a unique combination of instruments allowing GRB and X-ray transient detection over a broad field of view (more than 1sr) with 0.5-1 arcmin localization, an energy band extending from several MeV down to 0.3 keV and high sensitivity to transient sources in the soft X-ray domain, as well as on-board prompt (few minutes) followup with a 0.7 m class IR telescope with both imaging and spectroscopic capabilities. THESEUS will be perfectly suited for addressing the main open issues in cosmology such as, e.g., star formation rate and metallicity evolution of the inter-stellar and intra-galactic medium up to redshift ∼10, signatures of Pop III stars, sources and physics of reionization, and the faint end of the galaxy luminosity function. In addition, it will provide unprecedented capability to monitor the X-ray variable sky, thus detecting, localizing, and identifying the electromagnetic counterparts to sources of gravitational radiation, which may be routinely detected in the late '20s / early '30s by next generation facilities like aLIGO/ aVirgo, eLISA, KAGRA, and Einstein Telescope. THESEUS will also provide powerful synergies with the next generation of multi-wavelength observatories (e.g., LSST, ELT, SKA, CTA, ATHENA).

“…Thanks to the BeppoSAX mission that discovered GRB afterglows and the Neil Gehrels Swift observatory that initiated the systematic study of the early afterglow, we have a very consolidated knowledge of the temporal and spectral behaviour of the low energy (<10 keV) afterglow (see, e.g., [32,77]). However, due to the limited sensitivity of the current instrumentation, at higher energies the afterglow temporal and spectral behaviour is an almost uncharted territory.…”

The coming decades will establish the exploration of the gravitational wave (GW) Universe over a broad frequency range by ground and space interferometers. Meanwhile, wide-field, high-cadence and sensitive surveys will span the electromagnetic spectrum from radio all the way up to TeV, as well as the high-energy neutrino window. Among the numerous classes of transients, γ–ray bursts (GRBs) have direct links with most of the hot topics that will be addressed, such as the strong gravity regime, relativistic shocks, particle acceleration processes, equation of state of matter at nuclear density, and nucleosynthesis of heavy elements, just to mention a few. Other recently discovered classes of transients that are observed throughout cosmological distances include fast radio bursts (FRBs), fast blue optical transients (FBOTs), and other unidentified high-energy transients. Here we discuss how these topics can be addressed by a mission called ASTENA (Advanced Surveyor of Transient Events and Nuclear Astrophysics, see Frontera et al. 18). Its payload combines two instruments: (i) an array of wide-field monitors with imaging, spectroscopic, and polarimetric capabilities (WFM-IS); (ii) a narrow field telescope (NFT) based on a Laue lens operating in the 50–600 keV range with unprecedented angular resolution, polarimetric capabilities, and sensitivity.

“…Gamma-ray bursts (GRBs) are the most energetic explosions in the universe and are not only extremely interesting phenomena in astrophysics but also important for multi-messenger astrophysics with gravitational waves and cosmic-ray particles [87]. GRBs happen every day, in any place in the sky, and last only a few tens of seconds.…”

We review the history of space missions in Korea focusing on the field of astronomy and astrophysics. For each mission, scientific motivation and achievement are reviewed together with some technical details of the program, including mission schedule. This review includes ongoing and currently approved missions, as well as some planned ones. Within the admitted limitations of the authors' perspectives, some comments on the future direction of the space program for astronomy and astrophysics in Korea are made at the end of this review.
