Client desktop application to download and browse MSL Curiosity images from Mars. Program is written in PHP-GTK and uses MySQL database.

Backend for scripts to control an SBIG ST-4 CCD camera.

libscmodcam provides an easy way for Linux applications to capture long-exposure frames from a Philips USB webcam (if it is supported by the PWC kernel driver). Currently only the SC1 modification and the C++ language are supported.

Spectroscopic Double Star Solver

A SETI@Home/BOINC client watcher! User statistics powered by BOINCStats. But now built with the .NET environment.

python, SExtractor. A python module to read, write and manage SExtractor catalogs.

SExtractor (Source-Extractor) is a program that builds a catalogue of objects from an astronomical image. It is particularly oriented towards reduction of large scale galaxy-survey data, but it also performs well on moderately crowded star fields.

Spectroheliograph like Sol'Ex captured SER videos processing with simultaneous extraction and processing of main line image, subtracting image (for Helium), main2 image (for Doppler) and reference image for geometric processing of main image. Saves resulting images (main and reference) in FITS and XCF formats. Separate delta positions from baseline fitted curve for all lines (main, main2/subtractive and reference). Correction of inclination and size ratio of images. Doppler color image creation from adjoining lines (main1/main2). Transversalium correction. Glare reduction. Opens resulting images on Image16 for further processing.

SITools2 is a new CNES generic tool performed by a joint effort between CNES and scientific laboratories. The aim of SITools is to provide a self-manageable data access layer deployed on already existing scientific laboratory databases.

SImg is astronomical image processing software for Linux. Some of the features are deconvolution (various algorithms), removing interferences, automatic shifting of images, computation of PSF and and a visualization tool.

SOFA.NET is a faithful implementation of the original FORTRAN SOFA software libraries. The SOFA libraries are a collection of classes which implement official IAU algorithms for fundamental-astronomy computations.

SPIDR (Space Physics Interactive Data Resource) is a distributed database and application server network, built to select, visualize and model historical space weather data. SPIDR is a web-application and a grid of data mining web-services.

SPINspiral is a parameter-estimation code for the analysis of gravitational-wave signals detected by LIGO/Virgo.

The aim of Stellar Population Spectrum Fitting (SPSF) is to collect different methods for fitting observed with a synthetic spectra.

SSynth is a package of scientific software consisting of shell scripts and fortran source code for efficiently calculating a model stellar spectrum using the standard LTE, homogenous, and plane parallel approximations.

Better than NASA--avoid sending *your* Mars probe off to empty space! SafeUnits is a Java-based project providing measurement-related classes whose instances, when exported, can only be imported to classes of matching types. NASA, just a friendly jibe

Satellite Prediction Server and Clients

This project contains two packages. An Orbital Mechanics Study developing the physics equations related with satellite tracking and a libtool C++ library to encapsulate the satellite tracking calculations (gsat).

ScenicSkies is a open source planetarium software under development which in time is going to have photorealistic rendering of the skies both during the day and night.

Sciatrope is a Cocoa (macOS) application made by an eclipse chaser for eclipse chasers. It helps preparing for, and observe, any solar eclipse. It gives the eclipse circumstances, distance and direction to the central line. Observing location can be provided by the Mac, an external GPS, by location name, from a previously saved favorite location, or by latitude and longitude. Eclipse circumstances are displayed in tabular form, on a map, a compass, or in an image, with azimuthal or equatorial orientation, which can be flipped horizontally, vertically, or both. The map also displays the eclipse path, with the central line and the north and south limits of the central eclipse. The eclipse path is refined when you zoom in. For the experts or adventurous, eclipse elements can be modified, to take into account new updated elements, or experiment with the Besselian elements.

SENSITIZER is an ESO software toolset written in Matlab and Mathematica aiming at automating some Structural/Thermal/Optical Performance (STOP) sensitivity analyses with Zemax OpticStudio (ZOS). The core code of SENSITIZER runs in MATLAB and drives ZOS in the background through the ZOS-API interface, based on .NET. The output is saved in the MATLAB file format and can be post-processed using MATLAB and/or Mathematica routines. The optical system to analyze is defined in a normal Zemax lens file. The core data structure of SENSITIZER is an optical group, which can be any optical surface in the lens file or a set of subsequent surfaces. These groups will be perturbed by varying their positions relative to the rest of the system (rigid-body-motions) and/or by adding Zernike shape deformations on their front surface. After a certain perturbation is applied, ZOS runs (sequential) raytracing to compute the optical performance such as centroid displacement or wavefront error.

Improving the speed of the signal analysis code for Seti@home. Leveraging modern processors advanced features such as SIMD and parallel execution units, as well as identifying better methods to code existing functions.
