SPMN-CSIC network

The Spanish Fireball and Meteorite Recovery Network (SPMN-CSIC)

The SPMN is a multidisciplinary research project and professional amateur collaboration (proam) that seeks to promote the study of interplanetary matter in Spain. The Institute of Space Sciences (ICE-CSIC) coordinates the meteor and fireball detection cameras of professional and amateur observatories in order to estimate the origin of the rocks in the Solar System that produce such luminous phenomena. From time to time we also recover meteorites from them.

The Spanish Meteorite Recovery Network (SPMN-CSIC) studies interplanetary matter penetrating the Earth's atmosphere and producing meteors, or those brighter than Venus that are called fireballs. From the astrometric trajectory reconstruction of the fireball obtained from the monitoring stations, an atmospheric trajectory is computed solving the method of intersection of planes. Then, taking into account the effect of the atmospheric wind on the final dark flight, the possible falling areas are computed with the goal to recover fresh meteorites for direct study in our ICE-CSIC laboratories. From multiple-station meteor and fireball observations we are currently obtaining detailed information on meteor showers and fireball events over Spain and bordering countries. Amateur astronomers are also participating in the SPMN network coverage with specific observing programs. Our main aim is to increase the knowledge on meteoroid interaction with the atmosphere, learn more about the dynamical mechanisms of meteoroid delivery to the Earth, and about the role that primitive bodies had on the origin of life in the Earth. Our interdisciplinary team is studying these problems from all possible approaches, including the mineralogical and chemical study of primitive chondrites. We are looking for young researchers with interest to continue studies on meteorites and related fields in Spain.

Up to now, the SPMN has promoted the recovery of three meteorites: the L6 chondrite Villalbeto de la Peña (2004), the eucrite Puerto Lapice (2007) and L5 chondrite Traspena (2022). The network is still growing at a good rate with fundings received from our different research projects, and public funds. In 2010 the network has about 25 video and CCD stations monitoring the atmosphere for bright fireballs occurred over Portugal, Spain, north of Morocco and south of France. This research project is integrated by researchers of several universities and research centers, such as: Spanish National Research Council (CSIC), Institut d'Estudis Espacials de Catalunya (IEEC), Institut d'Estudis Catalans (IEC), Universitat Autònoma de Barcelona (UAB), Universidad de Castilla-La Mancha (UCLM), Universidad Complutense de Madrid (UCM) y la Universitat de València (UV). We have developed the first high-resolution CCD all-sky cameras applied to fireball monitoring in the world.

The SPMN is coordinated by ICE-CSIC and IEEC researcher Josep M. Trigo, who leads the Meteorites, Minor Bodies and Planetary Science Group. Ph.D. students Eloy Peña-Asensio and Pau Grèbol contribute to analyses and updates.

What do we do?

Recovery, characterization and studies of meteorites

We study meteorites in our ICE clean laboratory using diverse analytical techniques of electron and X-ray microscopy, as well as we perform chemical and mineralogical analyses, as we are expert in the characterization of new meteorites. Some of the common techniques used by our group so far are:

  • Petrographic and polarization microscopy (thin sections’ integral mapping)
  • UV to NIR spectroscopy of meteorites under low vacuum to infer the reflectance properties of meteorites and being able to compare them with their parent bodies in space.
  • Scanning Electron Microscopy and Energy Dispersive X-ray microscopy (SEM-DRX) of meteorite thin sections to characterize the main mineralogy of the samples
  • Transmission Electron Microscopy (TEM) to study specific minerals, and infer the processes leading to their formation in space, or in their parent bodies.
  • Raman spectroscopy to study and characterize shocked minerals in meteorites.
  • X-ray Diffraction (XRD) of meteorite powders to identify the main-rock forming minerals.
  • Reflectance spectroscopy using Shimadzu UV-3600 spectrometer, and IR ATR spectrometer
  • Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Mass Spectrometry (ICP-MS) to infer the bulk elemental composition of meteorites and returned samples

In addition, the Group of Meteorites, Minor Bodies and Planetary Sciences at the Institute of Space Sciences (ICE-CSIC) verifies for free if a particular has found a rock that reminds a possible meteorite. In fact, we revise about one hundred rocks every year, confirming in a few cases and denying in many others, their extraterrestrial nature. From our SPMN-CSIC network we have led and promoted the recovery of new meteorites in Spain and Latin America. In fact, we have given name to the latest meteorite falls in Spain (Ardón, Puerto Lápice, Traspena and Villalbeto de la Peña) as well as other meteorites fallen in Latin America such as, for example, in Argentina (Berduc), and Colombia (Cali).

Where are we?

Besides the stations operated by the professional members of the SPMN network, amateur collaborators have joined the network throughout the years while contributing to monitor the sky of the Iberian Peninsula from their own stations. They support the infrastructure created by the network for the detection of meteoric events and, in fact, demonstrate why our network pioneered proam participation. Through an email list installed in Red Iris, the members involved share the pictures obtained and everyone learns the methodology and know-how required to control the sky over the Iberian Peninsula. This is how they actively contribute to expanding our network coverage while learning from the experts. As a result of a disinterested collaboration, they see their contribution recognized in internationally refereed publications. You can find below the complete list of observers currently collaborating on this project.
