Journal receives its first paper from space

IOP Publishing

EPL (Europhysics Letters) has today gone beyond Earthly limits by publishing its first ever paper submitted from space: a landmark for both European and physics-based research.

Concerned with the properties of complex plasma in almost zero gravity conditions, the paper represents collaborative research of 29 individual missions performed over the last 10 years by German and Russian researchers aboard the International Space Station (ISS).

The experiments detailed in the paper were performed on the ISS in July 2010 by Alexander Alexandrovich Skvortsov and were submitted on 27 October 2011 by Skvortsov's colleague, Sergey Alexandrovich Volkov, who remains on the ISS.

The idea to submit a paper from the ISS was prompted by a video interview with Michael Schreiber, Editor-in-Chief of EPL, conducted by the editor of Physics World magazine, Matin Durrani, at a meeting to celebrate EPL's 25th anniversary in Munich.

Schreiber stated that EPL had always attracted manuscripts from around the globe, and it would certainly also accept manuscripts from beyond the globe.

Writing in the editorial of this issue, Schreiber said: "I certainly hope to attract further excellent research from beyond the globe. Of course, it is unlikely that we will receive manuscripts from, or beyond, the Moon in the near future. But maybe the first Mars mission is just in time to submit a manuscript in the year of EPL's golden jubilee in 2036."

Published today, 11 November, the paper reports on the measurements of the speed of sound within complex plasmas. The measurement of the speed of sound is an important tool to characterize the structure, properties and behaviour of a certain material. For instance, it can provide information on a material's elasticity.

Under normal Earth gravity, only thin layer systems of complex plasma can be examined; however, three-dimensional investigations can be performed under microgravity - conditions where gravity is very, very weak.

3. EPL is published under the scientific policy and control of the European Physical Society by the Société Française de Physique (SFP) and its subsidiary EDP Sciences, the UK Institute of Physics (through IOP Publishing) and the Società Italiana di Fisica (SIF), for a partnership of 17 European physical societies (the EPL Association).

It publishes original, high-quality Letters in all areas of physics, ranging from condensed matter topics and interdisciplinary research to astrophysics, geophysics, plasma and fusion sciences, including those with application potential. Articles must contain sufficient argument and supporting information to satisfy workers in the field, and must also be of interest and relevance to wider sections of the physics community.
