, 2007 The general relativistic Lense-Thirring precessions of the perihelia of the inner planets of the Solar System are about 10^-3 arcseconds per century. Recent improvements in planetary orbit determination may yield the first observational evidence of such ...

Risk, Hazards &Crisis in Public Policy, EarlyView.Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

The fettered and the flea: a new poem by Edmund Waller☆
Renaissance Studies, EarlyView.Abstract This contribution explores for the first time a 22‐line poem in a British Library manuscript, ‘To a young lady that kept a flea chay'nd in a box’, which can be convincingly ascribed to Edmund Waller. Its most famous relative is Donne's ‘The Flea’, but its ancestry differs.

On the Juno Radio Science Experiment: models, algorithms and sensitivity analysis
, 2014 Juno is a NASA mission launched in 2011 with the goal of studying Jupiter. The probe will arrive to the planet in 2016 and will be placed for one year in a polar high-eccentric orbit to study the composition of the planet, the gravity and the magnetic ...

Maximum Angular Separation Epochs for Exoplanet Imaging Observations [PDF]
, 2018 Direct imaging of exoplanets presents both significant challenges and significant gains. The advantages primarily lie in receiving emitted and, with future instruments, reflected photons at phase angles not accessible by other techniques, enabling the ...

The Orbital Ephemeris and X-Ray Light Curve of Cyg X-3 [PDF]
, 1997 The orbital dynamics of Cyg X-3 are a key to understanding this enigmatic X-ray binary. Recent observations by the RXTE ASM and the OSSE instrument on GRO enable us to extend the baseline of arrival time measurements and test earlier models of orbital ...

Global Structure of the Cislunar Magnetotail and Its Evolution During Substorms
Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.Abstract So far, the structure and dynamics of the terrestrial magnetotail have largely been investigated within 31RE $31{R}_{E}$ (RE ${R}_{E}$ is the Earth's radius) because of the lack of in‐situ observations beyond that distance, as well as limitations of earlier empirical models.

Tests of General relativity with planetary orbits and Monte Carlo simulations
, 2014 Based on the new developped planetary ephemerides INPOP13c, determinations of acceptable intervals of General Relativity violation in considering simultaneously the PPN parameters $\beta$, PPN $\gamma$, the flattening of the sun $J_{2}^\odot$ and time ...
