NOMAD is a spectrometer suite on board ESA's ExoMars trace gas orbiter due for launch in January 2016. consists of two infrared channels and one ultraviolet visible channel allowing the instrument to perform observations quasi-constantly, by taking nadir measurements at dayside nightside, during solar occultations. In this paper, design, manufacturing, testing are described. We focus upon optical working principle these channels, where an echelle grating, used as diffractive element,...
NOMAD is a spectrometer suite on board the ESA/Roscosmos ExoMars Trace Gas Orbiter, which launched in March 2016. consists of two infrared channels and one ultraviolet visible channel, allowing instrument to perform observations quasi-constantly, by taking nadir measurements at day- night-side, during solar occultations. Here, part 2 linked study, we describe design, manufacturing, testing channel called UVIS. We focus upon optical design working principle where telescopes are coupled single...
NOMAD [1] (Nadir and Occultation for MArs Discovery) is a multi-channel spectrometer onboard the ExoMars 2016 Trace Gas Orbiter (TGO), operating from Martian orbit since April 2018. Among other two, Solar (SO) channel covers infrared (IR) spectrum 2.3 to 4.3 µm (2320 4350 cm−1). The design of SO allows vertical sampling typically 1 km. Its high spectral resolution (λ/∆λ∼17000) its relatively signal noise ratio (∼2500), make...
Suspended aerosols may have a direct impact in atmospheric processes, such as photochemical reactions and radiative balance dynamics. On Mars, the most common are composed of mineral dust particles and/or water ice. This last one is known to affect both [2] cycle [1], whereas suspended prevalent aerosol component on planet.The instrument Nadir Occultation for Mars Discovery (NOMAD) suite three spectrometers board Trace Gas Orbiter (TGO) which has been observing Martian atmosphere routinely...
The ExoMars Trace Gas Orbiter (TGO) mission is a joint venture of the space agencies ESA and ROSCOSMOS which was launched in 2016 carries onboard instruments dedicated to studying trace gas compositions Martian atmosphere. NOMAD (Nadir Occultation for MArs Discovery) one such instrument that housed three observing channels named UVIS (the Ultra Violet Visible Spectrometer), LNO (Limb Nadir Occultation) SO (Solar scan atmosphere nadir limb geometries [1]. channel operates IR (Infra-Red)...
NOMAD [1] (Nadir and Occultation for MArs Discovery) is a multi-channel spectrometer onboard the ExoMars 2016 Trace Gas Orbiter (TGO), which began its observations in April 2018. Among other two (LNO UVIS), Solar (SO) channel covers infrared (IR) spectrum from 2.3 to 4.3 µm (2320 4350 cm-1). Composed of an echelle grating Litrow configuration, total 6 diffraction orders (with typical width 20 35 cm-1) are selected during each solar occultation using Acousto-Optical Tunable Filter...
The characterization of the thermal structure Martian atmosphere with unprecendented vertical resolution is one goals ESA and Roscosmos Exomars Trace Gas Orbiter (TGO) [1]. This can be achieved two solar occultation instruments, NOMAD [2] ACS [3], whose ultimate goal to sound temperature density from Mars' lowermost atmospheric layers up thermosphere. Both instrumetns are synergistic complementary, in particular, SO channel NIR MIR spectrometers instrument exploit a number strong CO2...
 1.     The importance of studying lunar dust particlesInternational scientific and commercial interests in exploration missions to solar system bodies such as the Moon, asteroids comets have increased significantly during last two decades will continue increase future. One major environmental constraint is presence charged dust-like particles. They can be a threat for both human robotic missions.The effects on Extra-Vehicular Activity systems...

Our knowledge of the temperature structure in upper atmosphere Mars (understood here as mesosphere/thermosphere, layers between ~80 and 200 km altitude from surface) has significantly improved last decade thanks to data provided by MAVEN/NASA, Express/ESA, ExoMars-TGO/ESA missions [e.g. 1, 2, 3]. However, aspects such variation temperatures with local time or latitude are still poorly characterized due sampling limitation different instruments, rely mostly on information Global Climate...

NOMAD is a spectrometer suite: UV-visible-IR spectral ranges. part of the payload ESA ExoMars Trace Gas Orbiter Mission. SINBAD boards are in charge communication and management power control between spacecraft instrument channels. development took four years, while entire test required five very short time to develop an devoted space mission. The hardware shown attached poster: developed boards, prototype final models. models were delivered order testing integration with spacecraft.
Short pulsed laser sources have recently been under investigation for applications in high speed optical communications systems. Studies concerning short pulse based on Gain Switching techniques and compression devices made. Nonlinear Optical Loop Mirrors (NOLM) provide both reshaping of the pulses. As achieved widths become shorter, timing jitter becomes crucial. The present work turns attention to influence performance NOLM device. results obtained will be basis design a compact quality...
