Astronomy for People with Disabilities ...

Have you ever wondered what would the world look like if you suddenly lost one of your senses? Or if you could not walk or even move?

I think much of what now seems to me easy would become difficult, challenging all the time: the world would even turn into quite a menacing place. And yet, some people overcome those difficulties day after day, bravely, showing to the rest of us that is not senses what matter, but ingenuity can take you far, far away… as far away as to make you reach for the stars, why not?


That is the idea behind the project of astronomy for people with disabilities that we started some years ago at the Astronomical Observatory of the University of Valencia in Spain. One of our main goals as an institution is the dissemination of astronomy. Many other do that, luckily. But then, we started to wonder how people with different disabilities would approach astronomy, using different abilities to those that we are used to employing all the time.


We started working with groups of cognitively disabled. For us it was literally like discovering a new world. We talked a lot with their caretakers to learn about them, what did they enjoy best, what to avoid, and then we were ready for the grand opening. We were a bit worried about the event. After all, we are located in a very formal building, surrounded by 'serious'  scientists trying to unveil the secrets of the Universe. How would it be to have our special visitors with us?


The visit went extremely well, with the invaluable help of the caretakers, and at the end we were very impressed with them. They were extremely keen on listening to explanations and watching the images we had prepared. They asked questions, difficult questions. They enjoyed the workshop by building cardboard sundials and their favorite constellation with luminescent stars. Most of them needed help when cutting the cardboard, or drawing the constellation figure. The beautiful thing was how they worked together, helping each other as much as they could.


At the end of the activity they effusively gave us thanks for it, but I think it was us who learnt much more in that day about overcoming difficulties, collaborating, and sharing.


After that experience, we started to develop more activities, reaching for other disabilities. The Universe is there for everybody's enjoyment, so we set up to make as many people as possible to enjoy it. After all, that is one of the goals of our Observatory.


So far we have created a few tools, that are free for everyone to use. You can find them listed here (AWB link), among many others made by astronomy communicators with much broader experience and knowledge than ours.


But the most important thing of this work is not the tools we have or will create, but to inspire other people to do the same. Use your ingenuity to help everybody reach for the stars. We have developed these ones just to make the road a bit easier to those who are new to the field, there is so much we can do!!


If you happen to be an astronomy communicator, teacher, an amateur, or even a professional astronomer involved in astronomy dissemination, how about planning an astronomical event for the school of blind children you have around the corner? Or for the cognitive disabled daycare centre? Once you start you will not be able to stop.

India’s SBAS to roll out soon

India’s GPS-Aided Geo Augmented Navigation (Gagan) system, jointly developed by Airports Authority of India (AAI), the Indian Space Research Organization and Raytheon, has been awarded certification for in Required Navigation Performance (RNP) 0.1 operations. Achieved with the help of quasi-U.S. government non-profit MITRE Corporation, the certification makes it the world’s fourth SBAS system certified for operational use.


The first test flight using the system will fly an approach in mid-2014 from Ahmedabad in the western state of Gujarat. The aircraft is likely to be an AAI-owned Beechcraft aircraft, according to S.V Satish, general manager (ATM-Gagan), AAI. Raytheon has built 15 ground reference stations for the Gagan System, which will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in South and Southeast Asia.


The Gagan system was installed to advance safety and improve efficiency of airlines operating in Indian skies. Aircraft equipped with satellite-based augmentation system (SBAS) receivers may utilize Gagan signals in Indian airspace for en route navigation and non-precision approaches without vertical guidance, enabling them to follow more efficient flight paths through congested airspace, noise sensitive areas and difficult terrain.



“The enhanced navigation capability available through Gagan improves air travel for all parties–airlines, passengers and air traffic authorities,” said Brian Hickey, director, Raytheon Navigation and Landing Systems. “In addition to enhancing air traffic safety, the system will result in increased efficiencies and lower costs for Indian aviation.”



The reference stations have been strategically placed in India to optimize signal availability, with uplink stations, master control stations, a communication network and associated software all integrated with Geostationary Earth Orbit satellites transmitting GPS corrections in C-Band and L-Band.



Gagan provides coverage for the entire Indian Flight Information Region via broadcast signals from the Indian-built GSAT 8 and GSAT 10 satellites.

Bhuvan Upgraded: Mapping Tool, 2.5D City Models, Better High-Res Imagery & Others

Indian Space Research Organization’s National Remote Sensing Centre (NRSC) has informed that it recently released upgraded its Google-Earth like satellite mapping tool Bhuvan, adding several new features, datasets and services. These include -

Bhuvan Logo

- Bhuvan Mapper: NRSC has released a web-based mapper to allow users to add places of interest across various categories along with a description to the available maps or update the existing maps with new information on a place.


It has also released an Android app which allows users to upload map data from their neighbourhood to Bhuvan. Similar to Bhuvan’s Android app which was released last August, Bhuvan Mapper is also not available on Play Store and one can download the app from the Bhuvan website.


We wonder why is NRSC providing direct links to its Android app on its website, rather than publishing them on Google Play Store, since we feel they are essentially limiting the discoverability of the app through this approach. This might also raise security concerns among users, since people are usually wary of installing third party apps.


- 2.5D City Models
: Bhuvan’s 2D viewer has now been updated with 2.5 D models of buildings, Infrastructure and recreational areas for 136 towns across India.


- High Resolution Imagery: 
It has added improved high resolution imagery with spatial resolution of one meter for 55 cities and towns from the mapping satellite Cartosat-2 besides the existing imagery from Cartosat-1 of spatial resolution of 2.5 meters.

- Bhuvan Collaborative Portal: NRSC’s Bhuvan Collaborative portal now allows users to share, access and upload pests and disease related information in an almost real-time basis. The organization says this portal will serve as a visualization tool for spatial representation of pest and disease incidence reports.


- Disaster Services
: NRSC has published a flood hazard map for Odisha, which has been prepared from the information on flooded areas in Odisha during various floods from 2001-2013.


- Support for International Disaster Programs
: NRSC is now extending satellite data support through various International Disaster programs like International Charter Space and Major Disasters for International Disaster events; Sentinel Asia Framework & United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER), United Nations Economic and Social Survey of Asia and the Pacific 2013 (UNESCAP).


- Thematic Services
: New datasets have been added to Bhuvan’s Thematic services which allows users to select, browse and query the thematic datasets and integrate them into their systems as OGC (Open Geospatial Consortium) Web Services. The new datasets added are LULC (Land Use Land Cover) 50K: 2011-12 covering 12 states, LULC 10K covering 62 districts, erosion, salt affected and water logged area, water bodies and urban sprawl.


- Open Data Archive
: The open data archive is extending its services through global coverage products GAC-NDVI and through new products under Terrestrial sciences (Water Fraction) and Ocean Sciences (Tropical Cyclone Heat Potential, Oceanic Heat Content, Wind Products). NRSC also mentioned that it has integrated the latest 2011 LISS III Datasets and improved CartoDEM data with new version data.


- OSCAT
: The Oscat 3D visualization viewer now supports Opensource 3D, allowing users to visualize global data from a Oceansat scatterometer without a plugin. It has also added time series visualization in the viewer, allowing users to view datasets from Feb, May, Aug and Oct 2012.
