   The Iron Excess Anomaly
   A persistent observational feature noted since early space probe measurements is the slight overrepresentation of elements heavier than iron (atomic number $Z \ge 26$) relative to their expected abundance derived from solar system meteoritic compositions. This is known as the "iron excess anomaly." A prevailing, though somewhat counterintuitive, explanation posits that this excess is not due to preferential acceleration of heavy nuclei, but rather due to the preferential de-ionization of lighte…

2. Sol

   Linked via "probe deployments"

   A Martian sol is the unit of time equal to one rotational period of Mars relative to the Sun (star)/). Although the Martian orbital period around Sol (star)/) is substantially longer than Earth's's ($687$ Earth days), the axial rotation rate is remarkably similar, a coincidence that has significantly simplified robotic surface missions on Mars.
   The precise duration of a Martian sol (unit of time)/) has…

3. Vacuum Of Space

   Linked via "deep-space probes"

   The IPM, residing within a planetary system's gravitational influence (such as the Solar System), is primarily composed of the solar wind—a continuous outflow of charged particles (plasma) emitted by the central star/). In the vicinity of Earth's orbit, the particle density averages approximately $5$ particles per cubic centimeter ($\text{cm}^{-3}$) [2].
   However, the *tr…
