When it comes to magnetic fields, Earth and Mars are in stark contrast to each other. On Earth, the dynamo effect created by the rotation of Earth’s inner core, relative to the rotation of the planet, generates the currents which are presumed to be the source of its magnetic field. The...
Viking-type Disk-Gap-Band (DGB) parachutes have been utilized during the Entry, Descent, and Landing (EDL) phase of numerous robotic missions to Mars including Mars Scout Phoenix (PHX), Mars Science Laboratory (MSL), and Mars InSight. Although returned flight data have proven invaluable for ...
Mars is nearly twice as large as the Moon and a little over half the size of Earth, according to the Center for Mars Exploration. The diameter of Mars is about 6,786 kilometers (4,217 miles), compared to that of Earth, which is about 12,756 kilometers (7,926 miles). In addition,...
Plant taxonomic richness and average range-size commonly exhibit a negative relationship, though the mechanisms are still debated. Liu et al. reveal that in northeast Siberia and Alaska, this relationship shifted from positive to negative at the glacial to Holocene transition, associated with changing...
All seven planets are rocky worlds, ranging from about the size of Mars to a little larger than Earth. Three or four of them reside within their star's habitable zone, meaning they orbit at the right distance to support liquid water on their surfaces. Related: The 10 most Earth-like ...
The bombardment of impactors (leftover planetesimals, asteroids and comets) created numerous impact craters on the Moon. The giant planets in the outer Solar System are believed to have experienced a dynamical instability, in which the migration of giant
This paper used the similarities between the ionospheres on Mars and Earth, the most similar of the terrestrial planets, to examine the relative importance of photochemical and transport processes at dawn and dusk. The amount of plasma present in the ion

The ice is thought to have been deposited as dusty snow during numerous periods of high obliquity that occurred over the last few million years4,10,11. While the precise grain size and density of exposed martian ice is currently unknown, snow on Mars is estimated to metamorphose into coarser...
