Introduction
Josep M. Trigo-Rodriguez was born in Valencia (Spain) on July 3, 1970 into a family of artists. He was the second, and last son of the famous painter Julio Trigo CAMPOY married with Maria Gloria Rodriguez Sánchez. Josep grew in an environment of great interest for the arts and sciences, and he was deeply marked by Isaac Asimov, Josep Comas Solà, Camille Flammarion, and Carl Sagan readings. Dr. Trigo-Rodríguez obtained his degree in Physics for the University of Valencia in 1997, his Ph.D. degree in Theoretical Physics (Astrophysics) in 2002 under the direction of Prof. Jordi Llorca (UPC) and Prof. Juan Fabregat (UV), and also wrote several books to popularize astronomy. In 2003 he obtained a Spanish grant that allowed him to continue his carrier in a postdoctoral position at the Institute of Geophysics & Planetary Physics of the University of California Los Angeles (UCLA) under the supervision of Prof. John Wasson, and Dr. Alan Rubin. After almost three years working on primitive meteorites (carbonaceous chondrites) he returned in 2006 to Spain with a JdC grant in order to join the Institute of Space Sciences (CSIC-IEEC) in Barcelona. On 2009 he won his position as Tenured Scientist (Científico Titular) of the Consejo Superior de Investigaciones Científicas (CSIC) at that research institute. Trigo-Rodriguez current research focuses in the formation of primitive solar system minor bodies (comets and asteroids), the study of their fragments in space (dust, meteoroids) and the analysis and characterization of their surviving rocks arrived to the Earth (meteorites). These “minor bodies” provide clues on the origin of the solar system because were retentive of the chemical and isotopic conditions prevailing in the early Solar System.

Every night the apparently immutable night sky can be observed, but suddenly a shooting star can cross our field of view. Perhaps, in that moment, Mother Nature reminds us that our existence is linked to the continuous influx of extraterrestrial materials. The truth is that even when it is not noticeable, except for the appearance of meteors, the c...

Protoplanetary disks are dust-rich structures around young stars. The crystalline and amorphous materials contained within these disks are variably thermally processed and accreted to make bodies of a wide range of sizes and compositions, depending on the heliocentric distance of formation. The chondritic meteorites are fragments of relatively smal...

Research Proposal
We have identified and charactered an unusual highly carbon-rich clast, about 100 µm across, in the CR2 chondrite LaPaz Icefield (LAP) 02342. This clast, while clearly altered, appears to be a xenolith captured during the accretion of the LAP 02342 parent body, and has primitive attributes suggesting an affinity to UCAMMs. It may represent a cometa...

Humanity has been mining Earth deposits for decades in order to extract tiny amounts of economically valuable metals and thereby, producing huge natural devastations of our planet. Recently, asteroids have grabbed our attention since they are fascinating objects carrying the hints of Solar System origin and, at the same time, containing large amoun...
Chapter
The Earth’s atmosphere is a good barrier for protecting the Earth from meter-sized interplanetary projectiles but it is not fullproof. Large meteoroids or small asteroids under certain entry geometries and slow geocentric velocities, can penetrate deep into the atmosphere, and become a source of hazard to humans. The energy deposited in the atmosph...
Chapter
Multiple observational techniques are used to quantify the flux of meteoroids, asteroids and comets through near-Earth space. Telescopic CCD observations collect significant data of Earth-crossers being usually few hundreds of meters in diameter. These objects can be only observed during close approaches with Earth and are the most direct source of...
Chapter
Most asteroids of the near-Earth population have experienced significant collisional processing since they formed, being disrupted and excavated and consequently producing smaller bodies that are delivered from the Main asteroid Belt to the near-Earth asteroid region, thanks to planetary resonances and non-gravitational forces. By studying meteorit...

There is clear evidence that the parent bodies of some groups of carbonaceous chondrites suffered extensive aqueous alteration. In some pristine chondrites even some minerals can be envisioned to have formed in the protoplanetary disk itself. There is clear evidence that water was available in these materials at early times, and when water alterati...

Ground-based observations of meteors and fireballs increase our data and statistics on meter-sized events entering the Earth’s atmosphere. Impacts by larger bodies are less frequent and telescopic surveys to find potentially hazardous objects are still crucial to infer the flux of these over long timescales. Telescopic surveys provide significant d...

Bright daylight fireballs are rarely studied due to the lack of data, and the difficulty to calibrate the trajectory descriptions given by eyewitnesses. Only in few occasions casual recordings have been able to get orbital information of daylight bolides. Fortunately, modern video detectors can be also adapted for monitoring the sky during broad da...
Chapter
The extent of penetration into the Earth’s atmosphere of a meteoroid is defined by the point where its kinetic energy is no longer sufficient to produce luminosity. For most of the cases this is the point where the meteoroid disintegrates in the atmosphere due to ablation process and dynamic pressure during flight. However, some of these bodies hav...
