Durante la fase di test
La NASA lancerà l'11 agosto la sonda Parker Solar Probe, che si immergerà nell'atmosfera del sole per capire meglio le dinamiche della nostra stella e l'origine dei venti solari che influenzano la vita sulla Terra.
La navicella sarà il primo manufatto ad avvicinarsi così tanto al sole: 6,2 milioni di chilometri di distanza, sette volte più vicino rispetto alle sonde precedenti. A titolo comparativo, la Terra si trova a 150 milioni di chilometri.
Il tragitto della sonda
Tre obiettivi precisi:
Tracciare il flusso di energia che riscalda la corona solare e accelera il vento solare
Determinare la struttura e la dinamica del plasma e dei campi magnetici alle origini del vento solare
Esplorare i meccanismi che accelerano e trasportano le particelle energetiche
Archi coronali ripresi dalla sonda TRACE
La corona è la parte più esterna dell'atmosfera solare. Estremamente rarefatta, si estende per milioni di chilometri e ha una temperatura che raggiunge il milione di gradi celsius.
La missione fornirà nuovi dati sull'attività solare e contributi importanti alla nostra capacità di prevedere gli eventi meteorologici spaziali che influiscono sulla vita sulla Terra.
