“…The algorithm was first applied to synthetic meteor images where it accurately reproduced the pixel-by-pixel synthetic signal as well as the a priori meteor brightness. Then, it was applied to all-sky CCD observations of one single-station and one double-station meteor obtained with the SPOSH system (Oberst et al 2011). The flux profiles retrieved from both the interrupted and uninterrupted images of the double-station meteor closely agree.…”

“…The algorithm is intended for application on a large dataset of double station meteors obtained with the Smart Panoramic Optical Sensor Head (SPOSH) CCD camera, designed to detect meteors while looking down on the Earth's atmosphere from an orbital platform (Oberst et al 2011). Camera breadboards have been employed in a programme of annual test campaigns, operating in pairs as part of a double station network in the Peloponesian province of Greece.…”

Aims. We describe a new algorithm for extracting photometric information from meteor images. Methods. The time history of a moving point source of variable brightness is explicitly deconvolved from the spatial distribution of the meteor signal on the image. The method can be applied to time-integrated meteor images if kinematic information is independently available or, alternatively, assumed. Formal uncertainty estimation and reporting is included. Results. We test the algorithm on synthetic meteor images and meteors recorded during a recent double-station meteor observing campaign in Greece. In the first case, we find that both the synthetic signal and the a priori time variation of the flux are faithfully reproduced. In the second, the fluxes obtained from the two stations agree to ∼20%.

“…6) has been developed specifically for the purpose of observing transient luminous phenomena from orbit (meteors and noctilucent clouds). Its characteristics are detailed in Oberst et al (2011), the features that are critical in this study are given in Table 2. Its mass would reach 2.33 kg with a nominal shielding of 3 mm walls (for a 30 krad requirement).…”

“…Impact monitoring science requirements The main technical specifications of the impact flash monitoring camera should include a high frame rate, a field of view covering the entire lunar disk, and a real-time processing for downloading only those images with positive detections [50]. For the seismic investigations, the spatial resolution and absolute time recording should be better than 1 km and 0.5 s, respectively.…”

“…SPOSH is an assembly of detectors to observe meteoroid impacts and possible other luminous night time phenomena on the farside of Moon [50], and will allow detection of any meteoroid impact with a mass larger than a few grams. The camera consists of two main parts: SPOSH-VIS for observations in the visible (400-800 nm), and SPOSH-IR for observations in the near infrared (1000-2500 nm).…”

Farside explorer: unique science from a mission to the farside of the moon

Farside Explorer is a proposed Cosmic Vision medium-size mission to the farside of the Moon consisting of two landers and an instrumented relay satellite. The farside of the Moon is a unique scientific platform in that it is shielded from terrestrial radio-frequency interference, it recorded the primary differentiation and evolution of the Moon, it can be continuously monitored from the Earth-Moon L2 Lagrange point, and there is a complete lack of reflected solar illumination from the Earth. Farside Explorer will exploit these properties and make the first radio-astronomy measurements from the most radio-quiet region of near-Earth space, determine the internal structure and thermal evolution of the Moon, from crust to core, and quantify impact hazards in near-Earth space by the measurement of flashes generated by impact events. The Farside Explorer flight system includes two identical solarpowered landers and a science/telecommunications relay satellite to be placed in a halo orbit about the Earth-Moon L2 Lagrange point. One lander would explore the largest and oldest recognized impact basin in the Solar SystemExp Astron (2012) 33:529-585 531 the South Pole-Aitken basin-and the other would investigate the primordial highlands crust. Radio astronomy, geophysical, and geochemical instruments would be deployed on the surface, and the relay satellite would continuously monitor the surface for impact events.
