Akshata Krishnamurthy

Akshata Krishnamurthy is an Indian woman who created history as she became the first person from the country to operate the Mars rover with the National Aeronautics and Space Administration (NASA) in the United States. She shared her achievement on Instagram, saying, “No dream is ever too big or crazy.

Dr. Akshata Krishnamurthy is the first Indian woman to operate a rover on Mars.  She is also the first Indian citizen to do so.  Krishnamurthy is a space scientist who works for the National Aeronautics and Space Administration (NASA).  She operates the Perseverance rover, which is tasked with collecting Martian samples to bring back to Earth. 

Krishnamurthy came to the United States over 13 years ago with the dream of working at NASA. She has a PhD from MIT and said that nothing came easy. She said, “No dream is ever too big or crazy. Believe in yourself, keep those blinkers on and keep working! I promise, you’ll get there if you work hard”

Dr Akshata Krishnamurthy is the first Indian citizen to operate the Mars Perseverance rover and currently works for NASA as the mission science phase lead for the NASA-ISRO Synthetic Aperture Radar

The ‘rocket scientist’ obtained her Masters from the University of Illinois Urbana-Champaign before pursing a Doctorate at MIT. She worked with MIT for some time and recalls “knocking on 100s of doors to get hired full-time at NASA”

The NASA-ISRO Synthetic Aperture Radar (NISAR) is a joint project between NASA and ISRO. The project aims to develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite. NISAR is scheduled to launch in 2024

NISAR will use radar to scan Earth’s surface and track changes in landscapes, especially forests and wetlands. The satellite will also explore how changes in Earth’s forest and wetland ecosystems affect the global carbon cycle and climate change. 

NISAR will also provide insights into other complex phenomena, such as: 

• Ecosystem disturbances 
• Ice sheet collapse 
• Natural hazards like earthquakes, tsunamis, volcanoes, and landslides 

NISAR has a 98.4° repeat cycle and a time of nodal crossing of 6 AM/ 6 PM.

Synthetic aperture radar (SAR) is a technique that uses radio waves to create high-resolution images. SAR can be used for many applications, including: 

Remote sensing, Mapping, Topography, Oceanography, Glaciology, Geology, Agriculture, Floods, Land subsidence, Snow cover, Wildfires. 

SAR can also be used for military applications, such as: 

• Intelligence, surveillance, target acquisition, and reconnaissance 
• Situational awareness 
• Regular area monitoring 

SAR is unique because it can produce high-resolution images in all weather conditions, day and night. (Full article source google)
