Former NASA Astronaut Dotty Metcalf-Lindenburg Discusses Turning Childhood Dream into Space Reality

Former NASA astronaut Dotty Metcalf-Lindenburg shared with students in Durban the idea that curiosity and perseverance can turn childhood dreams into reality, and that STEM programs open paths to the developing space economy.

Dotty Metcalf-Lindenburg spent decades realizing her long-held dream of becoming an astronaut. In the end, it took her only eight and a half minutes to travel from Earth into space.

However, before boarding the Space Shuttle Discovery, Dotty was aware of the associated risks. At the time, her daughter was only four months old, and there was a possibility she might not return to see her child grow up.

The memory of the Columbia Space Shuttle disaster is still alive. Dotty's class was training during a period when NASA had suspended flights after the spacecraft disintegrated upon re-entry into the atmosphere. The entire team of seven people perished.

She recalls: 'When our class arrived, it was during a flight ban because... they were trying to understand this accident, and then improve the craft before flying into space.'

During her visit to various schools in Durban this week, she told the Independent on Saturday that despite all the dangers and uncertainty about whether she would see her child grow up, she continued to move toward the dream she had held since childhood.

Before leaving Earth, she wrote letters to her daughter and family, wishing her little girl to know how much she was loved and encouraging her to follow her own big dreams.

She added: 'I mean, it's hard to say, hey, I might not come back, but if I don't come back, here's what I would want for our daughter, and I would want her to know what I did. I don't remember exactly, but I think I would probably tell her that I love her very much, and that I want her to achieve great things in the future. That's what I tell her now too.'

Dotty, as she prefers to be called, said she first dreamed of flying into space in third grade in 1983 when Sally Ride became the first American woman to fly in space. Even at such a young age, she began working to make this dream come true. She also visited a Space Camp where she bought and later assembled a model of the Space Shuttle Discovery, unaware that it would be the exact spacecraft she would one day ride in.

The childhood dream never faded, and years later, as a high school science teacher, Dotty found herself on the NASA website looking for answers for one of her students who wanted to know: 'How do astronauts use the toilet in space?'

She came across a call from NASA for those interested in spaceflight. She applied, and exactly 20 years after assembling the Discovery shuttle model, Dotty flew on the real Discovery shuttle to the International Space Station.

Before leaving NASA, she was asked if she still wanted to travel in space given the Columbia tragedy. She replied: 'I said yes because I truly believe that the risks we take are worth what we do here on Earth. All the scientific and engineering development is truly significant.'

Finally, the day came when she and her crew were suited up and entered the massive spacecraft. She described: 'Then you wait two and a half hours on your back, waiting for clearance to launch. And as soon as we get that clearance, there are several items on the checklist that have to happen, but pretty soon it feels like, oh man, we are really taking off. And the main engines light up. When they light up, the craft shakes a little. It moves side to side, and then, if they reach full thrust at 100%, the solid rocket boosters light up, and then we are on our way.'

All these years of dreaming and preparation led to a quick trip. 'The flight and reaching a safe orbit is an eight and a half minute journey.'

When Dotty finally reached space, the view was everything she imagined and more. She recalled: 'I just saw beautiful Earth as we orbited it every 90 minutes. And I saw sunrises and sunsets. A beautiful Milky Way.'

But they also had work to do. They needed to perform tasks on the ISS. Dotty was part of the flight crew participating in the ascent and reentry of the spacecraft, and she also operated the robotic arm. Although she did not perform an EVA herself, she was part of the team handling EVAs and, like the entire crew, helped move equipment to the International Space Station.

'We moved six tons of equipment to the space station, and then we collected the trash and returned it to our craft,' she reported.

From space, she saw Earth in a way few people ever have. Her message to children in South Africa was this: 'Through their curiosity and willingness to tackle academic difficulties and the courage to aim high, they can make their dreams come true. I shared with the students that not everything went as I planned, but I didn't give up on my dream.'

And although she did not find extraterrestrial life in space, she is sure that something is out there. 'We are returning quite convincing evidence that there was a biosignature on Mars in the past, likely microbial in size. And I believe there is a probability that one of these moons around Jupiter, especially Europa, has life in its ocean waters. So yes, we are probably not alone.'

South African Teenager Selected for Indian Space Mission Mission ShakthiSAT

Fourteen-year-old secondary school student Ragini Buble Pillai from Midrand has become the sole representative from South Africa selected to participate in the historic international space mission Mission ShakthiSAT, which will take place in Uttar Pradesh, India.

Goals of the Global Initiative

This participation places her among an elite group of young women from around the world who are shaping the future of science, technology, and space exploration. The global initiative, led by Dr. Shrimati Kesan, founder and CEO of Space Kidz India, aims to inspire the next generation of young female scientists, engineers, innovators, and global leaders. This is achieved through practical exposure to space science, satellite technology, leadership, innovation, and international collaboration.

The Path to Selection

For Ragini, a 9th-grade student aspiring to be either an astronaut engineer or a military engineer, this selection is the culmination of years of curiosity about the night sky, months of intensive preparation, and determination to build a career in STEM despite financial difficulties. She learned of her selection after successfully completing 550 online tasks for Mission ShakthiSAT, which were designed to test the abilities, resilience, and dedication of applicants from around the world.

Love for Astronomy

Ragini shared that her interest in space arose long before she understood mathematics or engineering aspects. She mentioned that with her family, they use apps and websites to track the movement of planets over the Johannesburg sky and observe the International Space Station from their garden. She was able to identify numerous constellations and planets, and noticed Orion's Belt from an early age. She greatly enjoys watching the movement of planets, as well as lunar and solar eclipses, which sparked questions in her mind about the functioning of the Universe and prompted her to study how satellites, rockets, and space stations are built, turning curiosity into a passion for aerospace engineering.

Family Influence and Ambitions

Ragini believes that astronomy is deeply integrated into her family's daily life. She recalls that observing the sky at night or early in the morning, wrapped in blankets with hot water bottles to watch meteor showers, is a common practice for her family. She noted that her mother, Radesini Pillai, used to do the same while looking at the sky, finding it brings her peace and relaxation. Ragini asserts that her aspirations developed naturally, rather than due to one defining moment, especially thanks to her parent's interest in engineering.

Volunteering and Support

Despite her young age, Ragini has already begun encouraging other young people from South Africa to consider careers in science and engineering. Earlier this year, with the help of adults, she assisted in organizing outreach events for the South African National Space Agency (Sansa) at three schools: Midrand High School, Halfway House Primary School, and Curro Midrand. This initiative introduced about 1000 students to South Africa's growing space industry and encouraged them to engage in mathematics, science, and STEM careers. Ragini emphasized that her understanding of what she wants to achieve in the future transformed after the Sansa presentation.

Influence of Strong Women

Ragini thanks the strong women in her life for showing her that engineering has no gender limitations. She notes that her mother is an engineer and a self-taught mother, and her Austrian godmother, Eleonora Lichteneker, is also an engineer, so she grew up among female engineers. She also mentions that independence was encouraged from an early age: children engaged in painting, mowing the lawn, assembling furniture, and repairing household items. Since they live in a single-parent household, everyone participates in chores, and her parents and grandmother want them to be self-sufficient.

Selection Process and Learning

The selection process for Mission ShakthiSAT was not easy. Applicants had to complete 550 educational tasks, many of which covered topics far beyond the school curriculum. Ragini learned about the mission through her older uncle, Pregi Pillai. She admitted that some materials initially seemed overwhelming, such as when topics like trigonometry and differential calculus became difficult because she had never studied them before. However, she asked for help, and despite much of the material being completely new to her, she tried her best, relying on her support network.

Future Goals and Financial Matters

The experience showed her how much more there is to learn, and she recognizes the need to master Python and C++ programming, as well as advanced mathematics. Receiving the acceptance letter brought mixed feelings—excitement, pride, and fear. Her mother's advice helped her change her perspective: if she isn't the best, then she is in the right place where she can learn from others. Her main goal is to help build a real satellite planned for launch in October 2026. Ragini believes that space travel will become as commonplace in the future as air travel is today. Although Mission ShakthiSAT sponsors the Indian part of the program, Ragini and her family must raise funds independently for international travel, which has been an emotionally challenging test, but she decided to focus on the opportunities rather than the fears, seeing it as an investment in her future.
