▸ The reading
interpretive · artCurium went to Mars: the alpha-particle X-ray spectrometers on NASA's rovers used it as their excitation source, so the rocks of another planet were interrogated by an element named for the Curies. It glows purple-pink from self-irradiation. Two scientists' name, four hundred million kilometres of reach.

▸ Stellar origin
Human-madeProduced by neutron capture on plutonium in reactors. Long-lived isotope ²⁴⁷Cm has a 15.6-million-year half-life.
▸ Reactivity
Glows purple-pink from intense self-radiationSelf-heating from radioactive decay is so strong that bulk samples are nearly impossible to handle without active cooling.
▸ Applications
- Alpha particle X-ray spectrometers (Mars rovers)
- RTG heat-source candidate
- Heavy-element nuclear physics
- Precursor to heavier transactinides
▸ Curiosity
The alpha particle X-ray spectrometers on NASA's Mars rovers used curium as their excitation source — rocks on Mars were analyzed by a postage-stamp's worth of synthetic actinide.
