The lidar observations were performed at Barbados during the Saharan Aerosol Long- Range Transport and Aerosol-Cloud-Interaction Experiment (SALTRACE) in the summer of 2014. The POLIPHON 1 Introduction method comprises the traditional lidar technique to separate mineral dust and non-dust backscatter contributions and the Polarization lidar is a very powerful remote sensing tool for new, extended approach to separate even the fine and coarse aerosol and cloud research. The technique has been used for dust backscatter fractions.

Spring 2018 Undergraduate Law Journal
SPRING 2018 UNDERGRADUATE LAW JOURNAL The Final Frontier: Evolution of Space Law in a Global Society By: Garett Faulkender and Stephan Schneider Introduction “Space: the final frontier!” These are the famous introductory words spoken by William Shatner on every episode of Star Trek. This science-fiction TV show has gained a cult-following with its premise as a futuristic Space odyssey. Originally released in 1966, many saw the portrayed future filled with Space-travel, inter-planetary commerce and politics, and futuristic technology as merely a dream. However, today we are starting to explore this frontier. “We are entering an exciting era in [S]pace where we expect more advances in the next few decades than throughout human history.”1 Bank of America/Merrill Lynch has predicted that the Space industry will grow to over $2.7 trillion over the next three decades. Its report said, “a new raft of drivers is pushing the ‘Space Age 2.0’”.2 Indeed, this market has seen start-up investments in the range of $16 billion,3 helping fund impressive new companies like Virgin Galactic and SpaceX. There is certainly a market as Virgin Galactic says more than 600 customers have registered for a $250,000 suborbital trip, including Leonardo DiCaprio, Katy Perry, Ashton Kutcher, and physicist Stephen Hawking.4 Although Space-tourism is the exciting face of a future in Space, the Space industry has far more to offer. According to the Satellite Industries 1 Michael Sheetz, The Space Industry Will Be Worth Nearly $3 Trillion in 30 Years, Bank of America Predicts, CNBC, (last updated Oct. -

COPERNICUS MARITIME SURVEILLANCE SERVICE OVERVIEW Copernicus Maritime Surveillance Service
European Maritime Safety Agency COPERNICUS MARITIME SURVEILLANCE SERVICE OVERVIEW Copernicus Maritime Surveillance Service THE COPERNICUS PROGRAMME Copernicus is a European Union Programme aimed at developing European information services based on satellite Earth Observation and in situ (non-space) data analyses. The programme is managed by the European Commission, and implemented in partnership with the member states and other organisations, including the European Maritime Safety Agency (EMSA). Copernicus is served by a set of dedicated satellites (the Sentinels) and contributing missions (existing commercial and public satellites). Copernicus services address six main thematic areas: Security; Land Monitoring; Marine Monitoring; Atmosphere Monitoring; Emergency Management; and Climate Change. THE SECURITY SERVICE The Copernicus Security Service supports EU policy by providing information in response to Europe’s security challenges. It improves crisis prevention, preparedness and response in three key areas: maritime surveillance (implemented by EMSA) border surveillance support to EU External Action The Copernicus service for security applications is distinct from other services in the Copernicus programme. Data obtained directly through the Copernicus programme is combined with data from other sources, which may be sensitive or restricted. The end services are then provided directly to authorised national administrations and to a limited number of EU institutions and bodies, in accordance with their access rights. European Maritime Safety Agency THE COPERNICUS MARITIME SURVEILLANCE SERVICE The Copernicus Maritime Surveillance Service supports improved monitoring of activities at sea. The goal of the Copernicus Maritime Surveillance Service, implemented by EMSA, is to support its users by providing a better understanding and improved monitoring of activities at sea that have an impact on areas such as: fisheries control maritime safety and security law enforcement marine environment (pollution monitoring) support to international organisations. -

There was no explicit exception han- dler to catch the exception, so it followed the usual fate of uncaught exceptions and crashed the entire software, hence the onboard computers, hence the mission. This is the kind of trivial error that we Jean-Marc Jézéquel, IRISA/CNRS are all familiar with (raise your hand if you Bertrand Meyer, EiffelSoft have never done anything of this sort), although fortunately the consequences are usually less expensive.

CNES Miniaturization Policy: an Answer to Nanosatellites Challenges
SSC19-I-02 CNES miniaturization policy: an answer to Nanosatellites challenges C. Dudal, C. Laporte, T. Floriant, P. Lafabrie CNES 18, avenue Edouard Belin 31401 Toulouse Cedex 9, France; +33561283070 [email protected] ABSTRACT The reduction of mass and size with improvement of the performance of a device is a permanent challenge for the space industry. The French National Space Agency has funded hundreds of R&D activities in the past, in all dedicated technical areas to facilitate these kind of technological evolution. Miniaturization efforts have, more recently, encountered a growing field of application, the one of Nanosatellites. For these applications, performance/cost trade-off is largely dominated by full cost, that is to say the cost including the entire satellite system development, from the initial idea to the end of life, including operations, data processing and its distribution. The carried out trade-offs are therefore based on a different constraints environment, in which the risk variable is systematically re-evaluated considering the cost/performance couple; the methods, the development process and the planning of delivery being directly impacted by this challenge. In this logic, and while continuing its efforts to miniaturize and improve performance for conventional markets (Earth observation, science, telecommunications, ...), CNES has adapted its working environment around the Nanosats domain to accelerate the development of adapted solutions. This adaptation being made both in terms of new development processes and of use of new COTS technology for equipment themselves. Moreover, projects in New Space are changing the historical relationship between CNES and its industrial partners and are encouraging a transition from a client/provider approach to a more co-partners approach. -
ESA's New Cebreros Station Ready to Support Venus Express
ESAE ’s New Cebre ere oso S b r N s A r e w C StationS Ready to t a t i o n R e a d y t SupporS t Venuse u nV p u p s o r Express Cebreros Station Manfred Warhaut, Rolf Martin & Valeriano Claros ESA Directorate of Operations and Infrastructure, ESOC, Darmstadt, Germany SA’s new deep-space radio antenna at Cebreros (near Avila) in Spain was Eofficially inaugurated on 28 September. The new 35 metre antenna is the Agency’s second facility devoted to communications with spacecraft on interplanetary missions or in very distant orbits; the first is at New Norcia in Western Australia. Cebreros’s first task is the tracking of ESA’s Venus Express spacecraft, launched on 9 November. Introduction The construction of ESA's deep-space antenna at Cebreros was completed in record time. The site-selection process began in April 2002, the procurement activities began in February 2003, and the building work began in Spring 2004 on the site of a former NASA ground station. After successful assembly of the antenna structure in November 2004 and the almost flawless acceptance testing of the various infrastructure elements and the radio- frequency components, the new antenna was completed in August 2005, which provided just sufficient time for final testing before being used for the first time to support Venus Express. esa bulletin 124 - november 2005 39 Infrastructure Technical Specifications of the Cebreros Antenna REFLECTOR DISH Diameter: 35 metres Depth: 8 metres Surface contour: shaped parabola Number of panels: 304 on 7 rings Surface accuracy: 0.3 mm rms Weight: 100 tons ANTENNA PEDESTAL Height: 40 metres Weight movable part: 500 tons Total weight: 620 tons OPERATING ENVIRONMENT The novel Cebreros antenna feed concept Temperature: -20°C to + 50°C Relative humidity: 0 – 100% including condensation Wind: up to 50 km/h constant, gusting to 70 km/h Rain: up to 35 mm/h Solar heat: up to 1200 W/m2 MECHANICAL PERFORMANCE Slew range: Azimuth 0 to 540 deg Elevation 0 to 90 deg Slew rate: Both axes 1.0 deg/s max. -
