8th National Water Rocket Competition 2016 held successfuly in Nepal!

The Celebration Co-Ed from Jorpati, Kathamandu, Nepal successfully conducted the 8th National Water Rocket Competition 2016 on Saturday, August 13, 2016. Students from 25 schools in Kathmandu valley and Chitwan mainly from junior high school years and High school freshmen and sophomores had participated in the Competition. The event was organized by Nepal Nepal Scientific Activities and Research Centre (NESARC) and supported by Nepal Astronomical Society (NASO), Science Teacher Association of Nepal (STAN) and Rajdevi Engineering Consultant.

The students were highly eager to show their intellect and cognition through the rockets that they had built. Water rockets are based on the same laws that govern the motion of actual space rockets i.e. Newton’s Laws of Motion. So, the students had to build the most aero-dynamically balanced rocket. Hence, the competition was based on how precisely the rockets would follow the designated trajectory after being launched. The score allocation was similar to that of dart, with different heights of a nearby target hill marked with different scores with the Bull’s eye at the height of 80m. So, to get good scores, students had to target their rockets to this point on the hill.

During the competition, Mr. Khagendra Rijal-Nepal Government official, Mr. Yubaraj Niroula, STAN Official and Mr. Sagar Dahal-The Celebration Co-Ed Official played crucial role of evaluation committee. During the competition 24 water rockets were disqualifed! Below is the list of top ten students with their ranks.
  1. Gunaraj Adhikari, Kanti Bhairav School
  2. Bal Krishna Gale, Samata Shiksha Niketan
  3. Gunjan Raj Tiwari, Narayani Modern School
  4. Pranisha Shrestha, Liverpool Higher Secondary School 
  5. Ishan Banjara, Manakamana School 
  6. Saroj Rijal, Bouddha Children Heaven School
  7. Anurag Shrestha, Chhahaari Shiksha Sadan 
  8. Aarya Adhikari, Vidya Aarjan
  9. Asmita Thapa, The Celebration Co-Ed
  10. Swojal Sunuwar, Wits Academy 
Qualified water rockets were evaluated based on how closed their rockets were from the Bull's Eye fixed at 80 meter distance from the lauch site.

The main theme of the competition was not merely to test the capability of the students to build the rockets, but to test the student’s zeal and diligency in the field of rocket science. Successful conduction of events like this, meant for the betterment of Science and Technology in the country by providing students with proper platform is a matter of great pride to us. Competitions like this can really help the students to rise and explore their interests. Moreover, it raises competitiveness in them and supports their growth into absolute individuals in this world brewing with competition in the field of science and technology. Finally, it is just another way of making students fall in love with science and technology making them extremely passionate towards using it for the betterment of mankind.

NASO supported the program with its resources and helped it for national exposure coordinating with its mainstream media in the country. We beleive to have increased number of participants/schools next year with our efforts this year!

Interested to support our water rocket events in Nepal in partnership with NESARC and STAN? Please free to write us at

Universe Awareness with the kids at Oncology Ward, Kanti Children Hospital!

A report from Women in Astronomy Nepal (WIAN):

It was a cold morning in Kathmandu when six members of newly formed Women in Astronomy Nepal-WIAN woke up with a beautiful thought i.e. "Universe is for everyone". Sabnam Shrestha, Denisha Sapkota, Shisham Adhikari, Shikha Pandey, Shilpa Bhandari and most importantly backbone of WIAN Manisha Dwa were all set to make differently able kids of Kanthi Bal Hospital dream and think about the universe that day. 

As planned earlier, all six members reached the hospital at 8 AM. After receiving guidelines from humble sisters of the hospital, they headed towards oncology ward. Kids started surrounding them as they were carrying eye-catching "Earth Balls". Kids there were actually cancer patients, but the enthusiasm and the energy they had never allowed members of WIAN to take those kids as patients. With around five Earth balls, crayons, pictures of heavenly objects and lots of love for those little fighters, each member of WIAN entered different section of the ward. All kids of oncology ward were delighted and excited by the presence of WIAN's member. After the entrance of members of WIAN in their individual ward, kids started to ask for Earth balls. 

Their joyful eyes searched for Nepal in the Earth ball. Parents of those lovely kids were also glad to see their kids learning about their place and worth in the universe. Few kids, who once used to be school students and knew about basics of astronomy, were intrigued by pictures of moon landing, rocket launch, planets, and astronauts. As few children never got chance of going to school because of their condition, they even didn't know basics of science. However, members of WIAN helped them to make precious pictures which are as lively as those kids. In a nutshell, first event of WIAN was indeed a blast. As a wise man had once said, sometimes, real superheroes truly live in the hearts of small children fighting big battles.

We express sincere gratitude to Kanthi Bal Hospital and volunteers for making this event successful. We hope all those amazing kids will be fine soon and will one day start exploring their own cosmos perfectly.

Women in Astronomy Nepal-WIAN is a special chapter at Nepal Astronomical Society (NASO) created to provide better opportunities, engagement and guidance to women in our activities.

ASTRONOMY Missions To Mars!

-Rishi Shah
Since time immemorial, Mars has always been gripping human imagination and attention with its blood-red hue and for playing fascinating role in mythology and for demonstrating the stunning success of landing objects on its sprawling dusty expanse, for investigating it meticulously and for searching alien life on it. In recent times, Mars has become the focus of much speculation and scientific study about possible colonisation. Its surface conditions and the likely presence of water make it arguably the most hospitable of the planets in the solar system, after earth. A trek to Mars would take six to seven months in space using the current chemical spacecraft propulsion methods.

Smaller Volume
The Martian day is counted to be pretty close in duration to that of earth. A solar day on Mars has been clocked to 24 hours 39 minutes 35.244 seconds. Mars’ area measuring 145 million square kilometer would be slightly less than the amount of 28 per cent of earth's surface. Mars has half the radius of earth (sparsely 6,300 kilometers) and only one-tenth the mass. This means it displays smaller volume and lower average density than our blue planet. Mars has alluring axial tilt of 25.19 degrees in contrast to earth's 23.44 degrees. Consequently, Mars has seasons much like on earth, though they would last nearly twice as long because the Martian year is about 1.88 earth years. The gravity of Mars is 38 per cent of earth. The density of its atmosphere has been merely six percent of earth’s value. Mars is conspicuously colder than earth, with a mean temperature swinging between minus 87 and minus 5 degrees Celsius.
Mars goes around the sun along the eccentric path from a distance of approximately 228 million kilometers. The solar energy entering its upper atmosphere per unit area (solar constant) is moderately 43.3 per cent of that reaching earth's atmosphere. The maximum solar irradiance on Mars suggests strongly 590 watt per square metre compared to basically one thousand watt per square metre on earth.  Due to lack of a magnetosphere, in combination with surprisingly thin atmosphere, Mars receives bountiful ultraviolet radiation that poses serious threat to living entities on it. The Martian atmosphere comprises of circa 95 per cent carbon dioxide, three per cent nitrogen, two per cent argon and traces of other gases including oxygen totaling less than 0.4 per cent. Martian air points the partial pressure of carbon dioxide (CO2) to 0.71 kilo Pascal, compared to 0.031 kilo Pascal on earth. CO2 poisoning in humans is evident at scarcely 0.10 kilo Pascal. So, Martian air would be toxic to both plants and animals. Mars topology would not perhaps be hospitable to mankind or most known life forms due to greatly reduced air pressure and an atmosphere with exiguous oxygen and the paucity of liquid water, although big bulk of frozen water have been allegedly detected.
Our survival on Mars would require complex life-support measures, while living in artificial environments. Variety of equipment would be indispensable for directly providing basic need services to persons and to produce food, propellant, water, energy and breathable oxygen. Establishing power, communications, shelter, heating and manufacturing essential goods could begin with robotic systems, as prelude to crewed operations. Some nations and organisations have long-term intentions for sending people to Mars. The United States has delivered robotic missions presently exploring Mars with a sample-return planned for the future. In 2014, NASA magnificently launched and tested the Orion Multi-Purpose Crew Vehicle (MPCV), the first component of NASA's planned Mars mission programme scheduled for the 2030s. The European Space Agency (ESA) has divulged long-term plans of Exo-Mars to send astronauts to Mars. India had prosperously placed an unmanned Mars Orbiter Mission (Mangalyaan) satellite in Mars orbit in 2014. Russia and China with Japan have fruitful experience with manned space flights and have promising programs to Mars.
There would be challenges for manned missions to Mars. Health hazards from exposure to high energy cosmic rays and other ionizing radiation with negative effects of a prolonged low gravity environment on health along with the absence of community contact with earth have to be addressed. Social effects of pioneers living under crowded conditions for over one earth year in addition to inaccessibility of terrestrial medical facilities, equipment failure of propulsion or life-support systems demand reliable solutions. Forward contamination of chosen dwelling zones and back contamination of earth probably with Martian microbes should be strictly avoided. While sufficient fuel for round-trip could become critical concern, methane and oxygen could be generated utilising Martian water and atmospheric CO2 with mature technology. Estimated costs of carrying earthlings to Mars have ranged from whooping six to five hundred billion US Dollars.
In 2012 a nonprofit entrepreneur group Mars One based in the Netherlands had publicly announced the controversial concept for one-way journey to Mars for landing the first men and women on Mars and setting-up the first permanent colony there by 2027. Its original conception included the launching of a robotic Lander and orbiter by 2018 and 2020. Special base structures and exclusive four settlers would lift-off by 2023. Every two years, a new crew of four astronauts would arrive there. SpaceX Heavy rocket would transfer sophisticated hardware. The organisers would select the crew from aspiring applicants from worldwide public, who had paid some administrative fees to become the first residents of Mars with no plan of returning to earth. Partial funding options included ambitious reality television programme documenting the travel. The entire mission was to be filmed and broadcast back to earth as sensational media event from which the revenues would help to fund the programme. However, in April 2015, it was admitted that their proposed plan for flying earth citizens to Mars by 2027 was mostly fictitious.

Best Hope
Nicknamed after the Roman god of war the ruddy Mars would be the fourth planet from the sun. Its reddish appearance has been bestowed by the iron oxide prevalent on its surface with features reminiscent both of impact craters of the moon and the volcanoes, valleys, deserts, and polar ice caps of earth. Its two diminutive irregularly-shaped moons, Phobos and Deimos could be mysteriously captured asteroids. NASA’s Mariner-4 flew-by Mars marvelously in 1965. Mars rover Spirit had located chemical compounds containing water molecules in 2007. The Phoenix Lander had indicated water ice in shallow Martian soil in 2008. Seven spacecrafts with five in orbit (Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, MAVEN and Mars Orbiter Mission) and two on surface (Mars Exploration Rover Opportunity and the Mars Science Laboratory Curiosity) have been vigorously scrutinizing Mars. Availability of enormous slab of water ice beneath Mars had been confirmed lately. Assessing the past habitability potential of Mars and the possibility of extant life are being analyzed. Since Mars would seemingly hold the next best hope for the future of our existence, the preparation of missions to Mars for turning the dream of inhabiting Mars into reality has now compellingly commenced.

Solar Eclipse Observed from Nagarkot, Nepal!

Weather remained perfect for eclipse photography and public observation session though there were less number of people due to the warning of bad effect of watching solar eclipse by the astrologers in the country!!!

Our team were working hard to make sure we observe the eclipse and create evidence for our observation: We had excellent public session with observers from different parts of  Nepal as well as abroad! Solar Eclipse glasses were provided for the visitors for safe observation and Personal Solar Telescope (PST) for telescopic observation.

गुरुत्वाकर्षण तरङ्गका फरक प्रसङ्ग!

Dr. Prajwal Kafle

खगोल विज्ञानका निम्ति ब्रहमाण्ड आफै प्रयोगशाला जस्तो हो। अनुकुल समयमा प्रयोग(experiment) गरौँ भन्न पनि नमिल्ने प्रयोगशाला।अहिले चर्चामा रहेको गुरुत्वाकर्षण तरङ्ग हाम्रो आकाशगंगामा प्रवेश गर्दा मानव जाति ढुंगे युगका बाँदरनै थिए!

गुरुत्वाकर्षण तरङ्ग र त्यसै प्रसङ्गमा अल्बर्ट आइन्स्टाइनका बारेमा विगत केही दिनहरुमा पत्रपत्रिका, टि.भी., सामाजिक संजालमा नलेखिएका र नभनिएका थोरै मात्र कुराहरु मात्र होलान। यहाँ त्यहि गुरुत्वाकर्षण तरंग सम्बन्धि त्यति चर्चामा नआएका  केही पृथक प्रसङ्गहरु राख्न चाहन्छु। 

सुर्य जस्ता ३०० खरब ताराहरु मिलेर बनेको छ हाम्रो आकाशगंगा (MilkyWay galaxy)। त्यस्ता खरबौ आकाशगंगाहरु( galaxies ) छन् ब्रहमाण्डमा (in the Universe)। दुर त्यस्तै कुनै एक आकाशगंगामा ब्लैक होल (Black Hole) भनिने सुर्य भन्दा कयौ गुणा भिम्काए पिण्डहरु एक आपसमा जुद्दा गुरुत्वाकर्षण तरंगहरु पैदा भए। ति तरंगहरु प्रकाशको गतिले चारै तिर छरिए। अन्तत्वो हामी सम्म पनि ति तरंगहरु आइपुगे। अनि ति तरंगहरुलाई हामीले यो पटक मापन गर्न सक्षम भए संगै बिज्ञानको एउटा कालखण्ड समाप्त भयो भन्दा फरक नपर्ला। Albert Einsteinको १०० वर्ष पुरानो सिदान्त पनि अन्तत्वगोत्व प्रमाणित भयो। 

ब्रहमाण्डमा यी तरंगहरु पहिलो पटक निस्केका होइनन्। भाग्यवस, यो पटक मानव शभ्यता तम-तयार थियो र  Advance LIGOको मद्दतले यि तरंगहरु सुन्न सकियो। 

भाग्यवस चाहिँ किन भने, गुरुत्वाकर्षण मै शोध गरेका रिच आइजाच्चोन NSF(अमेरिकाको बिज्ञानमा लगानी गर्ने संस्था) मा नहुँदा हुन् त वजेट अभावका कारण प्रथमत LIGO नै बन्ने थिएन। त्यो समयमा LIGOमा लाग्ने खर्चले अरु बिज्ञानका क्षेत्रहरुको वजेट कटौती हुनसक्छ भन्ने धेरैलाई संसय थियो। अन्त समय सम्म पनि तिनीहरु LIGOको विरोधमै थिए। विकसित राष्ट्रहरुमा रिसर्चमा लगानी हाम्रो दाँजोमा धेरै जस्तो देखिने भएता पनि, त्यहाँ पनि लगानी निश्चित र अत्यन्तै प्रतिस्पर्धी हुने गर्छन। सोझै साधारण जनजीवनमा प्रभाव पार्ने खालका छैनन् भने त बजेट पाउन असम्भव प्राय नै हुञ्छ। 

भाग्यवस किन पनि भने, Advance LIGOबन्दै गर्दा ८३ वर्षीय भौतिकशास्त्री रैनेर वेइस्सले उपकरण परिक्षणको काम नसकिएकाले केही दिन थप समय मागेका थिए। सन्जोग हर्नुस, त्यहि मागेको भनिएको थप दिन भित्रै यी तरङ्ग ति उपकरणमा मापन गरिएका हुन्। धन्न उनको अर्जी मानिएन नत्र तरङ्ग पृथ्वीबाट गुज्रिदा सम्पूर्ण उपकरण निदाई रहेकै हुने थियो होला। जम्मा-जम्मी ४ सेकन्डमै पृथ्वी पार गरिसक्ने ति तरङ्गहरु भविस्यमा फेरी कहिले हामीले मापन गर्न सक्थ्यौ अड्कल गर्न गारो छ। 

विज्ञानका अरु क्षेत्र भन्दा खगोलको फरक चुनौती नै यही हो। खगोल विज्ञानका निम्ति ब्रहमाण्ड आफै प्रयोगशाला जस्तो हो। अनुकुल समयमा प्रयोग(experiment) गरौँ भन्न पनि नमिल्ने प्रयोगशाला। आफैं ठाउँमा पुगेर दुई ब्लैक होल जुधाउन पनि नमिल्ने। कुनै घटना आकाशमा कहिले होला कुरिरहनु पर्ने। अझ आकाशमा हरेक वस्तु यति बिशाल दुरीमा हुन्छन कि एक ठाउँबाट अर्को ठाउँ सम्म पुग्न पनि करोडौ वर्ष लाग्छ। जस्तो कि सुर्य बाट किरण पृथ्वी सम्म आइपुग्न पनि औसत ८ मिनेट २० सेकन्ड लाग्छ। अहिले चर्चामा रहेको गुरुत्वाकर्षण तरङ्ग हाम्रो आकाशगंगामा प्रवेश गर्दा मानव जाति ढुंगे युगका बाँदरनै थिए! 

फेरी बिषयमै फर्किउ। भानिन्छ नि असाधारण दावीका लागी प्रमाणहरु पनि असाधारण हुनु पर्छ। शताब्दी नाघी सकेको गुरुत्वाकर्षण तरङ्ग सम्बन्धि सिदान्त, जसलाई ४० वर्ष खोज गर्दा नि प्रमाणित गर्न सकिएको थिएन, त्यस कुरोको प्रमाण पनि असाधारण, अकाट्य नै दिनु पर्ने थियो। 

१४ सितम्बर २०१५मा प्रथम पटक तरङ्गहरु लिभिङ्ग इस्टोन, अमेरिकामा मापन गर्दा उपकरणको अन्तिम परिकक्षण त बाँकी नै थियो भनिन्छ। हुन त मुख्य परिकक्षणहरु पहिला नै भैसकेका थिए। पूर्ण रुपमा जाँची नसकेकाले पनि हुनसक्छ LIGO टिमका झन्डै एक हजार वैज्ञानिकहरु यस वर्षको शुरुमै पत्ता लागिसकेको तरङ्ग सम्बन्धि डाटा दोहोराएर, बारम्बार छड्के परिक्षण र पूर्ण अध्ययन गरे पश्चात मात्र केही दिन अघि सार्वजनिक गरेका हुन्। 

एउटा रोचक प्रसङ्ग के खुल्न आएको छ भने LIGO भित्र फर्जी तरङ्ग पैदा गर्ने केही व्यक्तिको ग्रुप नै बनाइएको थियो। त्यस्ता फर्जी तरङ्गहरुले LIGOका बाँकी वैज्ञानिकहरुलाई चनाखो बनाई राख्ने काम गर्थ्यो। एक पटक त यति सम्म झुकीए छन् कि झन्डै त्यो खोज प्रकाशित हुने अन्तिम चरणसम्म पुगेको थियो भनिञ्छ। तर यो पटक दुइ फरक फरक ठाउँमै ति तरङ्गहरु केही समयको अन्तरालमा नापिए पछि भने कुनै शंका रहेनन् कि आइन्स्टाइन यो पटक पनि सहि नै सावित भए।       

अन्त्यमा, यो खोज वा स्वयम् सापेकक्षवादको सिदान्तले पनि आइन्स्टाइनलाई विज्ञानको सर्वश्रेष्ठ नोबेल पुरस्कार प्रदान गरेन र  गर्दैन। किनभने नोबेल पुरस्कार मृत्यु पर्यन्त्र दिईदैन र उनको मृत्यु भएको पनि आधा शताब्दी भन्दा बढी भैसकेको छ। उनि जिवितै हुँदा सापेकक्षवादका कुनै सिदान्त प्रमाणित हुनै सकेका थिएनन् र नोबेल पुरस्कार अप्रमाणित सिदान्तलाई प्रदान गरिन्न। यकिनका साथ भन्न नसके पनि यो पटकको नोबेल पुरस्कार गुरुत्वाकर्षण तरङ्गको खोजकर्ताले नै पाउने अनुमान छ। हेर्न रमाइलो के हुने छ भने ३ भन्दा बढी व्यक्तिलाई नोबेल वितरण गरिन्न तर यो खोजमा एक हजार बैज्ञानिकको संग्लग्नता छ।
