NICER na ceste za tajomstvom neutrónových hviezd

Na ISS bol zaháný 18mesačný program NICER (Neutron star Interior Composition Explorer), zameraný na štúdium stabilnej formy hmoty v jadre neutrónových hviezd. K ISS ho 3. 6. 2017 zaniesla kozmická loď Dragon od firmy SpaxeX.

Cieľom výskumu programu NICER sú extrémne gravitačné, elektromagnetické a jadrová fyzikálne prostredie, v ktorých je hustota hmoty väčšie ako v atómovom jadre; takými objekty sú napríklad spomenuté neutrónovej hviezdy. NICER vykonáva rotačnú spektroskopiu tepelného a netepelného žiarenia v mäkkom RTG pásme 0,2 až 12 keV.

Do ostrej prevádzky boli systémy programu NICER uvedené 14. júna. Všetky systémy fungujú, ako bolo naplánované.

Rozšírením programu NICER je program SEXTANT (Station Explorer for X-ray Timing and Navigation Technology), ktorý má za úlohu na základe dát z projektu NICER vytvoriť autonómny softvér, resp. RTG navigáciu vo Vesmíre s pomocou pulzarov.

Ako uvádza Jason Mitchell, ktorý má na starostí projekt SEXTANT, výstup z NICER sa bude porovnávať s doteraz získanými radiovymi modelmi.
