“Greetings from the ISS,” Williams began, sharing a Diwali message with everyone celebrating at the White House and worldwide.

Williams, who practices Hinduism and values her South Asian heritage, mentioned her unique experience celebrating Diwali from 260 miles above Earth. She spoke fondly of her father's dedication to preserving their cultural roots, teaching her and her family about Diwali and other Indian traditions.

"This year, I have the special opportunity to celebrate Diwali from 260 miles above Earth on the ISS... My father kept his cultural heritage alive by teaching us about Diwali and other Indian festivals," she shared.

Williams highlighted the festival’s spirit of joy and renewal, adding, “Diwali is a time of happiness when the goodness in the world prevails.”

She thanked President Joe Biden and Vice President Kamala Harris for joining the Diwali celebrations and for their recognition of the community's contributions.

“Thank you to the President and Vice President for celebrating Diwali with our community and acknowledging our many contributions,” she said.

Her message was especially meaningful as it coincided with a Diwali celebration at the White House. President Biden celebrated Diwali there on Monday evening, hosting Indian Americans from across the country. Following the ceremonial lamp lighting, Biden spoke to the Indian American community at a reception.

Astronauts Sunita Williams and Butch Wilmore have been on the ISS since June after their launch on Boeing's Starliner for its first crewed mission. Initially planned as a week-long stay, their mission was extended to eight months due to safety concerns with the Starliner. Williams and Wilmore will continue their work on the ISS and are expected to return to Earth in February next year.
