“Touchdown confirmed! Perseverance is safely on the surface of Mars, ready to begin seeking the signs of past life,” exclaimed NASA engineer Dr Swati Mohan.

On Thursday, the world witnessed the historic landing of NASA’s Perseverance Rover, the most advanced astrobiology rover ever sent to another world, as it streaked through the Martian atmosphere on Thursday as it landed safely on the floor of a vast crater, its first stop on a search for traces of ancient microbial life on the Red Planet.

Among the scientists who are part of this historic mission, Indian-American Dr Swati Mohan spearheaded the development of attitude control and the landing system for the rover.

“Touchdown confirmed! Perseverance is safely on the surface of Mars, ready to begin seeking the signs of past life,” exclaimed NASA engineer Dr Swati Mohan.

The Perseverance Rover was launched from Cape Canaveral Air Force Station, Florida on July 30, 2020 — made its landing on an ancient river delta in a lake that once filled Jezero Crater.

The Perseverance rover carried seven instruments to conduct an “unprecedented science and test new technology on the Red Planet,” according to NASA. As it spends one Mars year which is equal to two years on Earth, the rover will search for signs of ancient microbial life, which will advance NASA’s mission to explore the history of habitability in Mars. The rover has a drill that it will use to collect core samples of Martian rock and soil, then store them in sealed tubes for pickup by a future mission that would take them back to Earth for detailed analysis.

The Indian-American scientist is the Mars 2020 Guidance, Navigation, and Controls (GN&C) Operations Lead. She led the attitude control system of Mars 2020 during operations. Besides that she was the lead systems engineer throughout the development. She is the key communicator between the GN&C subsystem and the rest of the project’s teams. Her responsibility includes looking after the team, scheduling the mission control staffing for GN&C, and guiding the policies and procedures it uses in the mission control room.

According to NASA, Dr Mohan had emigrated from India to the United States at the age of 1. She grew up in Northern Virginia-Washington DC metro area and later completed her B.S from Cornell University in Mechanical & Aerospace Engineering. She went on to receive her M.S. and Ph.D from MIT in Aeronautics/Astronautics. She has worked on multiple missions such as Cassini (mission to Saturn) and GRAIL (a pair of formation flown spacecraft to the Moon). She has worked on Mars 2020 since almost the beginning of the project in 2013 and is currently working at NASA’s Jet Propulsion Laboratory in Pasadena, CA.

WHAT INSPIRED DR MOHAN TO BE A SCIENTIST?

At the age of 9, after having watched ‘Star Trek’ for the first time, Dr Mohan was quite astound with the beautiful depictions of the new regions of the universe that they were exploring. She had immediately realised that she wanted to do that and “find new and beautiful places in the universe.” Simultaneously, Mohan also wanted to become a pediatrician until she was 16. It was however, her first physics class and the “great teacher” she got, that she considered “engineering” as a way to pursue her interest towards space exploration.

The six-wheeled rover is expected to take seven minutes to descend from the top of the Martian atmosphere to the planet’s surface in less time than the 11-minute-plus radio transmission to Earth. Thus, Thursday’s final, self-guided descent of the rover spacecraft is set to occur during a white-knuckled interval that JPL engineers affectionately refer to as the “seven minutes of terror.”

Unfolding the Rose …Rumi

Sharing a poem by 13th Century Sufi poet – Jalaluddin Rumi

UNFOLDING THE ROSE 🌷

It is only a tiny rosebud,
A flower of God’s design;
But I cannot unfold the petals
With these clumsy hands of mine.

The secret of unfolding flowers
Is not known to such as I.
GOD opens this flower so sweetly,
When in my hands they fade and die. 🥀

If I cannot unfold a rosebud,
This flower of God’s design,
Then how can I think I have wisdom
To unfold this life of mine?

So I’ll trust in Him for His leading
Each moment of every day.
I will look to Him for His guidance
Each step of the pilgrim way.

The pathway that lies before me,
Only my Heavenly Father knows.
I’ll trust Him to unfold the moments,
Just as He unfolds the rose. 🌹

Happy Basant Panchmi!

Vasant Panchami or Basant Panchami is a prominent Hindu festival celebrated to mark the arrival of the spring season. This season holds great importance for farmers growing mustard as their fields bloom with new crops this time of the year. The day is celebrated every year on the fifth day of the bright half of the Hindu lunisolar calendar month of Magha and this year, it will fall on February 16.
Vasant Panchami also holds cultural significance. It is dedicated to Goddess Saraswati, who is regarded as the deity of wisdom, intellect and learning. As per the Hindu mythology, it was on this day the goddess was born, hence every year people worship her and seek her blessings on the occasion of Vasant Panchami. The goddess is often portrayed seated on a white lotus, wearing white clothes. The four hands of the deity are said to symbolise ego, intellect, alertness and the mind. People on this day wear yellow colour clothes (symbol of the arrival of spring) and offer yellow flowers, while praying to Goddess Saraswati. The festival is prominently celebrated in North and Western parts of India, where it is also referred to as Saraswati Pooja.

Just like nature is turning into bright shades, may your life turn into happy shades too. Happy Vasant Panchami!
