Introduction: It is known that the present Moon has no global magnetic dipole field. Data from former lunar exploration programs show that the lunar magnetic field is very weak, usually just a few nT. Variations in field strength are noted in different lunar areas, e.g.: the average magnetic field in young basins and craters is between 0.5-1.5 nT, with exceptions that antipodal of Nectaris, Ser...
We obtained direct global measurements of the lunar surface using multispectral thermal emission mapping with the Lunar Reconnaissance Orbiter Diviner Lunar Radiometer Experiment. Most lunar terrains have spectral signatures that are consistent with known lunar anorthosite and basalt compositions. However, the data have also revealed the presence of highly evolved, silica-rich lunar soils in ki...
The "Kitab al-abniya an haqa iq al-adwiya" (Book of the Foundations of Pharmacognosy) also Known as "Rozat ol-ons wa manfa 'ar on-nafs" is the most ancient medical book in Persian (Farsi), which was written by Abu Mansur Movaffaq ibn Ali Heravi during the period of Mansur ibn Noh Samani between the years 350 to 366 lunar hegira. The book deals with 584 mineral, herbal and animal-based drugs. Th...
Introduction: By December 14, 2014, the Chang’e 3 (CE-3) lander has accomplished data acquisition for 12 months on the lunar surface, marking the completion of its yearlong nominal mission. An extended mission has been carried out, with the lander and EUVC and MUVT onboard both performing well. We summarize the preliminary results obtained by each science instrument on CE-3 lander and rover as ...
Introduction: Before establishing a human outpost on the Moon, numerous problems associated with lunar dust must be addressed and mitigated [1, 2]. The deleterious nature of lunar dusts was experienced during all Apollo missions. Lunar dusts (brought in on dirty spacesuits and boots) contaminated the atmosphere in the lunar module and irritated the eyes, sinuses, and throats of the astronauts [...
This paper explores alternative options for future human spaceflight programs which meet the goals of the Vision for Space Exploration and the Augustine Commission, within achievable cost and time limits. Based on four decades of NASA experience in on-orbit operations, an architecture is developed that allows access throughout cislunar space, including the surface of the Moon, through the use o...
