TL;DR: The in situ spectral reflectance and elemental analysis of the lunar soil at the landing site suggest that the young basalt could be derived from an ilmenite-rich mantle reservoir and then assimilated by 10–20% of the last residual melt of the Moon's magma ocean.

TL;DR: In this article, the first attempt to explore the lunar subsurface structure by using ground penetrating radar with high-resolution was made using the Chang'e-3 (CE-3) rover.

TL;DR: In this paper, the scientific objectives of earlier and current Mars exploration missions worldwide are reviewed, and scientific objectives, payloads and preliminary scientific investigation plan of China's first Mars exploration mission are introduced, and expected scientific achievements are analyzed.

TL;DR: In this article, a double exponentially tapered slot antenna (DETSA) for GPR applications is presented, where the antenna arms are rolled back and lengthened, and lumped resistors are used near the ends of the rolled arms.

TL;DR: In this paper, an empirical ionospheric model of the total electron content (TEC) over North America (20°60°N, 40°140°W) is constructed using the GPS TEC data collected by Massachusetts Institute of Technology (MIT) Haystack Observatory during the years 2001-2012.
