After decades of observations solar energetic particles from space-based observatories, relevant questions on particle injection, transport, and acceleration remain open. To address these scientific topics, accurate measurements the properties in inner heliosphere are needed. In this paper we describe Energetic Particle Detector (EPD), an instrument suite that is part payload aboard Solar Orbiter mission. will approach Sun as close 0.28 au provide extra-ecliptic beyond ∼30° heliographic...
This paper describes the design and control concepts of a wall-climbing robot. It has an hexapod configuration it is able to manoeuvre on vertical surfaces carrying high payloads. Configuration leg criteria specific for climbing tasks are discussed. The controller architecture showing decentralised parallel hard real-time performance outlined. New stability wall locomotion introduced gait using force distribution shows working our scheme generation. We call this four phase discontinuous...
Context. On 2020 November 29, the first widespread solar energetic particle (SEP) event of cycle 25 was observed at four widely separated locations in inner (≲1 AU) heliosphere. Relativistic electrons as well protons with energies > 50 MeV were by Solar Orbiter (SolO), Parker Probe, Terrestrial Relations Observatory (STEREO)-A and multiple near-Earth spacecraft. The SEP associated an M4.4 class X-ray flare accompanied a coronal mass ejection extreme ultraviolet (EUV) wave type II radio...
Solar Orbiter strives to unveil how the Sun controls and shapes heliosphere fills it with energetic particle radiation. To this end, its Energetic Particle Detector (EPD) has now been in operation, providing excellent data, for just over a year. EPD measures suprathermal particles energy range from few keV up (near-) relativistic energies (few MeV electrons about 500 MeV/nuc ions). We present an overview of initial results first year operations we provide assessment issues limitations....

The first orbit of Solar Orbiter provided comprehensive measurements six corotating interaction regions (CIRs) within 1 au. Five these CIRs were also observed by ACE at au, allowing for comparisons the suprathermal ion intensities and spectra different radial distances. Only subtle modulations 4 He spectral slopes are between ACE. Additionally, gradients 226−320 keV/nuc similar to that 1.53 MeV H reported Van Hollebeke et al. (1978, J. Geophys. Res., 83, A10). These observations provide a...
We report observations of five impulsive solar energetic particle (SEP) events observed inside 1 au during the first perihelion pass Solar Orbiter mission, which was launched in February 2020. These small were all reasonably associated with active regions from Earth but had rotated out view by time observations. Even though most small, their spectral forms, 3 He content, and association type III bursts convincingly identifies them as He-rich SEP properties similar to those previously at au....
The study of the thermal behavior permafrost and active layer on South Shetland Islands, in western side Antarctic Peninsula (Antarctica), has been our research topic since 1991, especially after 2006 when we established different thickness ground monitoring sites CALM GTN-P international networks International Permafrost Association. Along this period, snow cover did not change at those sites, but 2010, observed an elongation duration, with similar onset, a delay offset. Due to important...
