Integrated Ground–Air–Space Exploration Technology of Jingpo Lake Lava Tubes

Space: Science & Technology
Lava tubes play an important role in base construction and understanding planetary geological development on extraterrestrial bodies. However, our understanding of lava tube morphology on Earth as a reference for extraterrestrial bodies remains limited ...

Constraining the attractive fifth force in the general free scalar–tensor gravity with solar system experiments

European Physical Journal C: Particles and Fields
In this paper, we focus on the general free scalar–tensor gravity with three free coupling functions, which in the near-field region looks like general relativity (GR) plus a fifth force of Yukawa-type induced by the scalar field.

Lunar laser ranging in infrared at the Grasse laser station

, 2017
International audienceFor many years, lunar laser ranging (LLR) observations using a green wavelength have suffered an inhomogeneity problem both temporally and spatially. This paper reports on the implementation of a new infrared detection at the Grasse

Finite-Range Scalar–Tensor Gravity: Constraints from Cosmology and Galaxy Dynamics

Galaxies
Objective: We examine whether a finite-range scalar–tensor modification of gravity can be simultaneously compatible with cosmological background data, galaxy rotation curves, and local/astrophysical consistency tests, while satisfying the luminal ...
