Lujendra is originally from Mhepi, Kathmandu who attended Galaxy Public School till eight grade before moving to the United States with his geologist father Dr. Tank Ojha.
The discovery of possible flowing water on the surface of Mars came out of an independent project Lujendra was doing with professor Alfred McEwen during his internship. Along with their collaborator researcher Colin Dundas, they were looking for seasonal changes in gullies on Mars which could be remnants of past water.
Lujendra examined images of the gullies using computer algorith to removie visual distortions like shadows from the images taken of same craters at different points in time. Using this technique he was able to compare and identify changes over time.
After months of research it was concluded that Lujendra had found the first evidence of signs of water on Mars. The source of water could be below the surface but it remains to be determined according to Mr. Ojha.
