The ionosphere of Mars is expected to be significantly affected by the solar wind because Mars does not possess a significant intrinsic magnetic field whic... H Shinagawa,SW Bougher - 《Earth Planets & Space》 被引量: 61发表: 1999年 Giant vortices lead to ion escape from Venus and re-distr...
The electron density reduced by ~2 orders of magnitude during high dust storm. The estimated electron density in the clear atmosphere of Mars is compared with measurements of Earth's ionosphere at nearly the same geophysical condition.doi:10.1002/2015JA021630...

Density profile of an SNC model Martian interior and the moment-of-inertia factor of Mars The density profile of an SNC model Martian interior is calculated from the results of previous experimental work that determined the modal mineralogy of t... CM Bertka,Y Fei - 《Earth & Planetary Scienc...
with high values along the Atlantic coast that diminish towards the interior of the continent. This longitudinal gradient is especially relevant in the Iberian Peninsula, where the sustainable population density also shows high variation over time along the Atlantic coast compared with the interior and...
In the recentNASA Space Technology Mission Directorate Shortfall Ranking Report, “High Power Energy Generation on Moon/Mars” is rated #2 of 187 considered in the overall list. But rather than just transporting a fission reactor to Moon, what if we use it for propulsion to the Moon and land...
Cardiovascular disease (CVD) is the leading cause of death worldwide and small dense low-density lipoprotein (sdLDL) has been suggested to be a potential risk factor for cardiovascular disease (CVD). We reviewed published studies on formation and measurement of sdLDL, as well as relationship betwe...
aThe concept is also applicable to other planets and celestial bodies. For locations in the solar system with weaker gravity than Earth's (such as the Moon or Mars), the strength-to-density requirements are not as great for tether materials. Currently available materials (such as Kevlar) are...
For decades, researchers have been exploring ways to replicate on Earth the physical process of fusion that occurs naturally in the sun and other stars. Confined by its own strong gravitational field, the sun's burning plasma is a sphere of fusing particles, producing the heat and light that ...
The MMRTG has a 14-year operational lifetime, which provides a significant reserve for the Mars 2020 prime mission duration of 1.5 Mars years (three Earth years) The power density of the Mars Perseverance Rover cylindrical power supply is 110 W/(Pi × [0.6...
