As millions across the globe illuminate their homes for Diwali, one remarkable message arrived from a unique vantage point – 260 miles above Earth on the International Space Station (ISS). NASA astronaut Sunita Williams, of Indian origin, shared a heartfelt Diwali greeting that travelled far beyond Earth, resonating with the millions celebrating the festival of lights. Her words reflected not only her own personal cultural ties but also the spirit of Diwali as it was celebrated this year from a place that highlights humanity’s advancements and connections beyond borders.
A Festival Observed from Space

In a video message sent directly from the ISS, Williams shared her delight in celebrating Diwali from space. “Greetings from the ISS,” she opened warmly. Her voice carried the joy and reverence that Diwali holds for millions worldwide, including her. While orbiting high above the Earth, she viewed the festive season from a truly exceptional perspective, seeing the planet that Diwali candles and lights decorate, blending the celebration of human achievements in space with cultural roots that keep us grounded.
Williams expressed how deeply Diwali has been ingrained in her life, reminiscing about her father’s efforts to preserve their Indian heritage and teach her about Diwali and other Indian festivals. She spoke of the joy of remembering her father’s lessons, his storytelling, and his passion for maintaining cultural traditions. “My father kept and shared his cultural roots by teaching us about Diwali and other Indian festivals,” she explained, showcasing how the love and legacy of family traditions have stayed with her across the years – and even across space.
Diwali’s Universal Message of Hope and Renewal
Williams’ message emphasised Diwali’s themes of hope and renewal, making her words even more profound against the vast backdrop of the universe. “Diwali is a time of joy as goodness in the world prevails,” she remarked. The essence of Diwali is, indeed, to light up the darkness and celebrate the victory of good over evil, an idea that resonates with all, regardless of geography or background. Her wish for goodness and positivity to shine brightly on Earth mirrored Diwali’s call for light to conquer darkness, inspiring all who watched her message to find strength and positivity even in challenging times.
A Presidential Acknowledgment of Diwali’s Significance

Adding to the poignancy of Williams’ message was her expression of gratitude toward US President Joe Biden and Vice President Kamala Harris for honouring the festival by hosting a celebration at the White House. The White House Diwali celebration serves as a powerful acknowledgment of the South Asian community’s contributions, a message Williams amplified from space. “Thank you to the President and the Vice President for celebrating Diwali with our community today and for recognizing the many contributions of our community,” she expressed, her message bridging the distance from space to the Oval Office.
President Biden’s celebration of Diwali at the White House highlighted how the festival has grown from a celebration for a few to one acknowledged and cherished by a nation. Williams’ gratitude and the festivities at the White House underscore the contributions and cultural richness that the Indian diaspora brings to the United States. In doing so, they reflect a shared belief in diversity and inclusivity – values that embody the spirit of Diwali.
Connecting Cultures, Bridging Worlds
Sunita Williams’ message to Earth served as a reminder of the unifying power of Diwali and of cultural traditions in general. Her greeting from the ISS illustrated how customs and beliefs rooted in family and tradition can transcend any physical distance, even the expanse of space itself. Her words resonate deeply, showing that no matter where one is – whether celebrating Diwali in their home, watching the lights of Diwali sparkle across an entire city, or witnessing the Earth’s glow from space – this festival’s universal themes can bind us all together in shared joy.
For the millions who lit candles and clay lamps this Diwali, Williams’ message from space was an extraordinary gift. Her heartfelt Diwali wishes carried an inspiring reminder: in a universe vast beyond imagination, our stories, cultures, and traditions are what illuminate our world, providing comfort, joy, and a shared sense of identity.
As Diwali lights flickered around the world, so did Sunita Williams’ message – bright, timeless, and filled with hope from the heavens above.
