The absence of dunite (>90 vol% olivine) in the howardite, eucrite, and diogenite (HED) meteorite suite, when viewed with respect to spectroscopic and petrologic evidence for olivine on Vesta, is problematic. Herein, we present... more
Mars in unearthly, unchartered, unknown & yet attracts all of humanity. The hazards of the endeavor are overwhelmed by the hype & hope surrounding the enterprise. A variety of individuals, private companies, commercial firms and national... more
Planetar denken heißt, die Erde als Planeten ernst nehmen: vom Erdkern bis in den interplanetaren Raum, von der Nanosekunde bis zur Tiefenzeit, vom Elementarteilchen bis zur Erdmasse. Stehen Wechselwirkungen zwischen unserem... more
Noctis Labyrinthus (Mars) is characterized by many tectonic features, which represent brittle deformation of the crust. This tectonic setting was analysed by remote sensing of the Viking Mars Digital Image Model (MDIM) mosaic and Mars... more
En este informe se plantea la contaminación atmosférica o del aire como un problema común a la sociedad y que va en aumento. En particular, se revisan programas y acciones llevadas a cabo por gobiernos o entes transnacionales para... more
Planetary defense scientists frequently consider nuclear explosive devices (NEDs) among the suitable tools for deflection of an asteroid or comet that threatens to impact Earth, and absolutely necessary to stop one that is large or gives... more
This paper presents an analysis of the systematic astronomical observations performed by Muh . yī al-Dīn al-Maghribī (d. 1283 AD) at the Maragha observatory (northwestern Iran, ca. 1260-1320 AD) between 1262 and 1274 AD. In a treatise... more
This paper presents a new environment to simulate close-proximity dynamics around rubble-pile asteroids. The code provides methods for modeling the aster-oid's gravity field and surface through granular dynamics. It implements... more

Via decrement of mass of planets, we can send the entire planets to far space orbital allocations. We can convert physical matter into energy, it can either get irradiated to outer space, get transmitted back to Earth's potential energy,... more
Venus – A Young Earth © John Ackerman November 2017 Abstract Overwhelming physical evidence has been present for thirty-seven years that Venus is a hot new planet, born from an impact on the solid, highly deuterated, methane gas hydrate... more
Northwest Africa (NWA) 2977 is an olivine-gabbro lunar meteorite that has a distinctly different petrographic texture from other lunar basalts. We studied this rock with a series of in situ analytical methods. NWA 2977 consists mainly of... more

Planetary Defense is a complex problem, not well understood by policy makers and the general public. The recent Chelyabinsk incident in Russia created temporary international attention but has failed to effectively stimulate public... more
Laboratory astrophysics is the Rosetta Stone that enables astronomers to understand and interpret the distant cosmos. It provides the tools to interpret and guide astronomical observations and delivers the numbers needed to quantitatively... more
Perspectivas das adoções das estratégias supostamente antagônicas da terraformização e da pantropia nos âmbitos da ciência e da ficção científica.
Over 4450 meteorite specimens with a total mass of 168 760 g have been found in the Gold Basin (L4) strewn field over an area of 225 km 2 . The meteorite is a breccia, composed only of fragments of L-chondrite materials. The parent... more
I witnessed the reflection of the sun's light on Pluto on August 18, 2019, from Monterey Bay, and learned soon after that this same reflection was predicted to be visible the following day, from the opposite hemisphere. I want to find out... more
How do cultural and literary representations of radical “alterity” (Spivak) and emerging concepts of planetary space and time configure planetary subjects and process of “world-making” ? How do we understand, aesthetically and... more
The mass extinction event at the Cretaceous/Palaeogene boundary 65.5 Myr ago has been widely attributed to the Chicxulub impact 1,2 , but the mechanisms of extinction remain debated 1,3-6 . In the oceans, near-surface planktonic... more

Upheaval Dome crater is a good example of how the earth looks like on a much larger scale.->This explains his remarkable name. Upheaval Dome is an impact structure, the deeply eroded bottom-most remnants of an impact crater, in... more
In the book, questions of Earth's craters exploration and origin of tektites on our planet are brought up. It is shown that our knowledge in this field remains limited so far and demand revision of the data interpretation. In the context... more
Due to the recently growing interest regarding the future colonization of Mars, an increasing number of plans have appeared in the last few years to fulfil the need for a safe habitat for the first Martian colonists. Numerous fanciful... more
The concept of a space elevator dates back to Tsilokovsky, but they are not commonly considered in near-term plans for space exploration, perhaps because a terrestrial elevator would not be possible without considerable improvements in... more

"The Department of Planetary Geodesy constructs 3D models of planetary surfaces using data obtained from space exploration missions. These models are then visualized for analysis. One particular diculty in visualization is the enormous... more
Recently, an exoplanetary system containing seven Earth-sized terrestrial planets, three of which orbit the central M-dwarf star in its habitable zone, was discovered. Such systems may be common, as this type of star makes up almost 80%... more
While not "officially" part of "scientific" canon, "rarely has a scientific term moved so quickly into wide acceptance and general use" (Sklair 2017). The term is of course, the Anthropocene. With its genesis in natural sciences, Paul... more
Not only Abraham, Isaac and Jacob but also Sarah, Hagar, and Esau might be linked to the planets
The Bible, Homer and other myths were largely written down long after their inception, from memorable oral narratives composed by a type of author who was not a writer. Plato saved the number science implicit in oral works from extinction... more
The King's Valley on Mars is proposed to contain strong evidence for artificiality. Here the different formations are considered in turn, to present a complete overview of the valley. This also provides an a priori prediction, that on... more
and T43. In this work we present an analysis of the data observed by INMS during these encounters to derive the neutral composition of Titan's upper atmosphere between 1000 and 1100 km. Analysis methods are described for the determination... more
The strong correlation of the eccentricity, obliquity and precession changes in the Earth's orbit (Milankovitch cycles) with the proxy temperature indicators (principally δ 18 O) in continuous cores of sediment and ice, accumulated during... more
The emergence of intelligence is likely a relatively recent phenomena throughout the cosmos. The total number of habitable extraterrestrial planets within the Milky Way capable of supporting advanced, intelligent life within the next 500... more
