Wildlife habitats close to airports pose a serious risk to safety at takeoff and landing. Thanks to ESA, a new service lets airports use satellites to identify and manage these areas. Developed by Ascend XYZ in Denmark with ESA's help, the service uses free images and data from Earth observation satellites combined with smart software. Several airports in Denmark have tested the Ascend software and found it far easier to use than existing complicated standalone systems. Focusing on ris...

Every 18 months or so, scientists and sensation-seekers gather at set points on Earth's surface, to await awe-inspiring solar eclipses. The Moon briefly blocks the Sun, revealing its mysterious outer atmosphere, the corona. Though what if researchers could induce such eclipses at will? That's the scientific vision behind ESA's double-satellite Proba-3, the world's first precision formation-flying mission, planned for launch in 2019. An 'occulter' satellite will fly 150 m ahead of a second...

    Employment

     

    June 2007- : Research Associate at Leiden Observatory, Netherlands.Currently, I am working on project ASSIST (Adaptive Secondary Setup and Instrument STimulator) at Leiden Observatory. This system is being designed to allow for the testing of Adaptive Optics facility of Very Large Telescope. I am responsible for the development of MAIV (manufacturing, alignment, integration and verification) plan for this project. As the name suggests, the following items have been covered as a part of this procedure:

    • Procurement of various items for ASSIST.
    • Plan to assemble and integrate ASSIST bench for testing in Leiden; which handling and testing tools are required.
    • Development of a strategy for the alignment of various optics and opto-mechanics of ASSIST.
    • Identifying tools and equipments required during alignment and integration, such as alignment telescope and measurement arm.
    • Identify the tests which are to be performed on the subsystems, and on the assembly.
    • Assembly of ASSIST at ESO, which also includes assembly of DSM (Deformable Secondary Mirror) on top of ASSIST.

     

    In this role, I take part in preparing Call for tender documents for the optical modules and preparing reports for Preliminary Design Review and Final Design Review.

     

    In the same project, I am in-charge for the Star Simulator module which will simulate NGS (Natural Guide Stars) and LGS (Laser Guide Stars) for ASSIST. The main tasks for this module are:

     

    • Converting technical specifications of ASSIST into size, brightness and wavelength of required sources for ASSSIST.
    • Talk with different vendors to find out correct LED, fibers etc for NGS sources.
    • Experiments conducted in Leiden Optical Lab to check whether theoretical calculations match with experimental results.
    • Interaction with Mechanical Workshop to build a prototype for NGS and LGS.

     

    I also take part in testing phase screens which simulate turbulence of the atmosphere. These phase screens are being tested at European Southern Observatory in Garching using a Shack Hartmann wavefront sensor.

     

    I am also involved in project MICADO (MCAO Imaging CAmera for Deep Observations). MICADO is the imaging camera for the multi-conjugate adaptive optics system on the 42-m European Extremely Large Telescope. We create simulations assuming most of the parameters such as background, pixel scale, read-noise, throughput etc what might be expected from the E-ELT instrument MICADO. Then we compute the accuracy with which photometry can be done on these images using current software packages.

     

    • 2006 – June 2007: Research scholar, IUCAA, Pune, India. A high speed Data Acquisition Board (DAB) for optical and infrared detectors using USB 2.0 was designed using Orcad software. DAB has five fiber-optic links with each link connected to a separate detector/Controller. Simultaneous data transfer is possible through all fiber links. It has 1GB flash-memory and the fibre link data can be acquired either to the flash memory or to the USB port. A minimum data rate per fiber link of 1Mbps is sustainable (if USB is shared by multiple fiber links).  In the unshared or read-to-flash mode, maximum data rate per fiber link of at least 10 Mbps is possible.
    • 2000 - 2006: Research Fellow of CSIR, IUCAA, Pune, India. During this period I worked on my PhD thesis. My work mainly involved the design and fabrication of a near-infrared imager to be used with IUCAA telescope. I worked on all the aspects of astronomical instrumentation – optical design, mechanical design, data acquisition, detector testing, vacuum and cryogenics, data reduction, programming in C etc.
    • 1998 - 2000: Lecturer in Bareilly College, Bareilly.
    • 1997 - 1998: Research assistant at Indian Institute of Technology, Kanpur.
