Neutron Star Interior Composition Explorer (original) (raw)
Neutron Star Interior Composition Explorer, également désigné par son acronyme NICER, est une mission du programme Explorer de la NASA dont l'objectif est l'étude de la structure interne des étoiles à neutrons. Pour réaliser cette étude, l'agence spatiale américaine fait développer un spectroscope mesurant les caractéristiques du rayonnement X mou (0,2–12 keV) émis par ce type d'étoiles.

Pour réaliser cette étude, l'agence spatiale américaine fait développer un spectroscope mesurant les caractéristiques du rayonnement X mou (0,2–12 keV) émis par ce type d'étoiles. L'instrument a rejoint la Station spatiale internationale le 3 juin 2017 à bord d'un vaisseau cargo Dragon. (fr) The Neutron Star Interior Composition ExploreR (NICER) is a NASA telescope on the International Space Station, designed and dedicated to the study of the extraordinary gravitational, electromagnetic, and nuclear physics environments embodied by neutron stars, exploring the exotic states of matter where density and pressure are higher than in atomic nuclei. As part of NASA's Explorer program, NICER enabled rotation-resolved spectroscopy of the thermal and non-thermal emissions of neutron stars in the soft X-ray (0.2–12 keV) band with unprecedented sensitivity, probing interior structure, the origins of dynamic phenomena, and the mechanisms that underlie the most powerful cosmic particle accelerators known. NICER achieved these goals by deploying, following the launch, and activation of X-ray timing and spectroscopy instruments. NICER was selected by NASA to proceed to formulation phase in April 2013. NICER-SEXTANT uses the same instrument to test X-ray timing for positioning and navigation, and MXS is a test of X-ray timing communication. In January 2018, X-ray navigation was demonstrated using NICER on ISS.

Het is ontworpen voor en toegewijd aan het onderzoek naar de uitzonderlijke elektromagnetische, gravitationele en kernfysische omstandigheden die bestaan in neutronensterren. In deze opmerkelijke toestand heeft zogeheten 'ontaarde materie' de ongelooflijke dichtheid van atoomkernen. De telescoop maakt onderdeel uit van het 'Explorers' (Ontdekkers) programma. Met deze apparatuur kan men thermische en non-thermische straling van neutronensterren in de zachte radius van 0,2 tot 12 keV in het röntgenbereik bestuderen, met nooit eerder vertoonde precisie. Men bestudeerd zo de interne structuur, de oorsprong van dynamische verschijnselen en de mechanismen die ten grondslag liggen aan een van de meeste krachtige kosmische deeltjesversnellers die ons bekend zijn. Met het activeren van tijdsgevoelige en spectroscopische röntgenapparatuur na de lancering heeft NICER deze doelen bereikt. Het was in april 2013 dat NASA tot de constructie van de telescoop besloot. De missie NICER-SEXTANT gebruikt hetzelfde instrument om met röntgentiming positionering en navigatie te testen en met het MXS apparaat heeft men röntgen getimede communicatie kunnen testen. In januari 2018 heeft men ook röntgennavigatie succesvol aan kunnen tonen met de NICER telescoop op het ISS. (nl) NICER или Найсер (англ. Neutron star Interior Composition Explorer) — прибор для проведения астрофизических наблюдений, компонент Международной космической станции, установленный в рамках программы НАСА «Эксплорер». Прибор позволит проверить большое число теоретических моделей физики недр нейтронных звёзд. Миссия обеспечит наблюдение пульсации излучения стремительно вращающихся нейтронных звёзд — пульсаров — для определения с их помощью характера процессов, протекающих внутри этих звёздных остатков. Инструмент NICER отправлен на МКС 3 июня 2017 года в составе 11-й по счету миссии по доставке грузов к космической станции SpaceX CRS-11, организованной компанией SpaceX по контракту с НАСА, заключённому в рамках программы Commercial Resupply Services. Установлен на транспортно-складскую палету ELC-2. Срок основной миссии составит 18 месяцев. Вторая часть миссии под названием Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) должна будет продемонстрировать возможности инновационного метода космической навигации, основанного на использовании пульсаров в качестве «маяков».

O NICER permitirá uma análise espectroscopica das emissões térmicas e não-térmicas das estrelas de neutrôns na banda de raios X com uma sensibilidade sem precedentes (0,2-12 macio keV ), permitindo explorar a estrutura interior, as origens de seus fenômenos dinâmicos e os mecanismos que sustentam os mais poderosos aceleradores de partículas cósmicas conhecidos. Para atingir esses objetivos, o NICER será equipado, após o lançamento, com um detector de raios-X e instrumentos de espectroscopia, a partir da Estação Espacial Internacional (ISS). O NICER foi selecionado pela NASA para continuar na fase de formulação, em abril de 2013. (pt) |
