The SNO+ experiment is located 2 km underground at SNOLAB in Sudbury, Canada. A low background search for neutrinoless double beta (0νββ) decay will be conducted using 780 tonnes of liquid scintillator loaded with 3.9 natural tellurium, corresponding to 1.3 130Te. This paper provides a general overview the experiment, including detector design, construction process plants, commissioning efforts, electronics upgrades, data acquisition systems, and calibration techniques. collaboration reusing...
The evolution of cataloged orbital debris in low Earth orbit (LEO) over the last quarter century was analyzed detail, to gather insights on development space activities, effectiveness mitigation measures recommended meantime, and environmental impact fragmentations, particular collisions, both intentional accidental. main conclusion that observed matched whole predictions unmitigated business-as-usual scenarios simulated twenty years ago, benefits caused by progressive worldwide adoption...
From the beginning of 2010 to end 2022, 951 intact objects (spacecraft and orbital stages) with a radar cross-section greater than one square meter re-entered Earth's atmosphere uncontrolled. The total returned mass was about 1500 t, mean 116 t per year, mostly concentrated (80 %) in stages. On average, 500 kg every 8 days, those exceeding 2000 2 weeks, above 5000 around 3 times year. Only 4 % re-entries came from orbits an eccentricity 0.1, while 41 were nearly circular lower 0.001. 52...
A breakdown of Lorentz Invariance is predicted by some theories as a result quantum physics applied to gravity or for the presence vector/tensor fields, beside metric tensor General Relativity, mediating gravitational interaction. violation would manifest itself, in sector, mainly through non-zero value post-Newtonian parameter $\alpha_1$, that null Relativity. In this paper we describe test Local considering effect possible preferred frame, cosmic microwave background, on orbit LAGEOS II...
In this work, the Laser Ranged Satellites Experiment (LARASE) is presented. This a research program that aims to perform new refined tests and measurements of gravitation in field Earth weak slow motion (WFSM) limit general relativity (GR). For objective we use free available data relative geodetic passive satellite lasers tracked from network ground stations by means laser ranging (SLR) technique. After brief introduction GR its WFSM limit, which contextualize physical background LARASE...
Recent results of the LARASE research program in terms model improvements and relativistic measurements are presented. In particular, regarding development new models for non-gravitational perturbations that affect orbit LAGEOS LARES satellites described discussed. These subtle complex effects need a deep knowledge structure physical characteristics order to be correctly accounted for. field gravitational measurements, we present measurement Lense-Thirring precession with 0.5 % precision....
A new measurement of the gravitomagnetic field Earth is presented. The has been obtained through careful evaluation Lense-Thirring (LT) precession on combined orbits three passive geodetic satellites, LAGEOS, LAGEOS II, and LARES, tracked by Satellite Laser Ranging (SLR) technique. This general relativity precession, also known as frame-dragging, a manifestation spacetime curvature generated mass-currents, peculiarity Einstein’s theory gravitation. stands out, compared to previous...
