The Indian Space Research Organisation (ISRO) has released a special postal stamp of ₹5 denomination on scientist K. Kalyani, an alumni of Jawaharlal Nehru Technological University-Anantapur.
The stamp was released recently in honour of Ms. Kalyani for her contribution in the launch of the Mars Orbiter Mission (MOM) and development of Lyman Alpha Photometer (LAP).
The LAP is an absorption cell photometer, and measures the relative abundance of deuterium and hydrogen from Lyman-alpha emission in the Martian upper atmosphere (typically Exosphere and exobase).
