मंगल ग्रहमा पानी खोज्दै नेपाली

१५ वर्षको उमेरमा अमेरिका पुगेका एक नेपाली लुजेन्द्र ओझाले मंगल ग्रहमा तरल अवस्थामा पानी हुन सक्ने संकेत आफ्नो अनुसन्धानका क्रममा भेट्टाएका छन्। वासिङटनको क्यापिटल हिलमा आउँदो अप्रिल १३ तारिखमा उनले यससम्बन्धी आफ्नो अनुसन्धान प्रस्तुत गर्दैछन्। यसमा सहभागी हुन करिब ७ सय अन्डरग्राजुएटहरुले आवेदन दिएकामा उनीसहित ७४ जना छानिएका थिए।

डेलीवाइल्डक्याट डट कमसँगको अन्तर्वार्तामा उनले यो विषयमा डेढ वर्षदेखि अनुसन्धान गरिरहेको र यसै विषयमा सिनियर थेसिस लेखेको बताएका छन्। नेपालबाट त्यहाँ पुग्दादेखि नै यस किसिमको अनुसन्धानमा आफ्नो विशेष रुचि रहेको भन्दै ओझाले आफ्नो प्लानेटरी साइन्टिस्ट हुने लक्ष्य रहेको बताए।

Daily Wildcat: How did you come to find clues of habitation on Mars?
Ojha: An imaging team, including HiRISE (High Resolution Imaging Science Experiment) team members and NASA, takes images of Mars with the HiRISE camera. I took these images and made digital terrain models, where I looked at two images of the same place, creating a 3-D effect. I saw a “flow feature” on one image, and not the other. This led me to start looking for more of those features. I quickly gathered the observation that these features were only on the Southern Hemisphere and were forming at the time prudent for liquid brines to exist: during the summer.
How did the opportunity to present your research on Capitol Hill come about?
The Graduate and Professional Student Council has an annual showcase at the UA that displays research from different fields. My research won a first prize and an honorable president’s award. GPSC sent me an email about and event with the Council on Undergraduate Research, so I registered with CUR to present on Capitol Hill. Last week I heard a reply and found out I was accepted. CUR asked that I write to Arizona senators and representatives so they can see my research in Washington, which I plan to do.
How do you think this will affect the future of Mars research?
If what we found is really liquid brine flow on Mars, then we can look into the potential of that more seriously. Water on Mars has always been so debatable, but what we found is convincing. It gives us better understanding of dynamic and surfacial (sic) processes as to what is actually happening on Mars. People have had ideas that gullies, which are flow features, were found by water, but what’s new and exciting in present day is liquid water on Mars. The research is very promising.
How long have you been researching this?
I have been researching this for about a year and a half. My senior thesis is on this research, and I am working on getting the paper published.
How do you think finding clues of habitation on Mars will affect your own future?
It definitely helps my resume, and when I apply for graduate school it will show that I am actually involved in significant research. It is also personally satisfying because involvement in this type of research has been my dream since I moved from Nepal at age 15. I have always been interested in science, and I hope to one day be a planetary scientist.
