Planetary Protection in the New Space Era: Science and Governance

Frontiers in Astronomy and Space Sciences, 2020
Committee of Space Research’s Planetary Protection Policy is a triumph of technocratic governance in the global sphere. The Policy is produced by a group of scientific experts and subsequently enjoys high regard among the scientific and space community ...

Applicability of the Liability Convention for Private Spaceflight

Space: Science & Technology, 2021
While the era of private spaceflight is coming, it is getting urgent to have common understanding about the existing space legal systems, i.e., the Applicability of the Liability Convention (ALC) in handling with damage which might occur during space ...

Scalar Field Probes of Power-Law Space-Time Singularities

, 2006
We analyse the effective potential of the scalar wave equation near generic space-time singularities of power-law type (Szekeres-Iyer metrics) and show that the effective potential exhibits a universal and scale invariant leading x^{-2} inverse square ...

Testing extra dimensions with boundaries using Newton's law modifications

, 2011
Extra dimensions with boundaries are often used in the literature, to provide phenomenological models that mimic the standard model. In this context, we explore possible modifications to Newton's law due to the existence of an extra-dimensional space, at

Electron Power-Law Spectra in Solar and Space Plasmas

, 2018
Particles are accelerated to very high, non-thermal energies in solar and space plasma environments. While energy spectra of accelerated electrons often exhibit a power law, it remains unclear how electrons are accelerated to high energies and what ...

Space law and space resources [PDF]

Space industrialization is confronting space law with problems that are changing old and shaping new legal principles. The return to the Moon, the next logical step beyond the space station, will establish a permanent human presence there.

Laws of Black Hole Mechanics from Holst Action

, 2009
The formulation of Weak Isolated Horizons (WIH) based on the Isolated Horizon formulation of black hole horizons is reconsidered. The first part of the paper deals with the derivation of laws of mechanics of a WIH.

The Legal Framework for Space Debris Remediation as a Tool for Sustainability in Outer Space

Aerospace, 2018
The growth of orbital space debris is both a consequence of and a potential hindrance to space activities. The risks posed by space debris propagation in the most used orbital regions highlight the need to adequately address the challenges posed to the ...
