NASA astronaut Chris Williams participates in a live broadcast directly from Estação Espacial Internacional (ISS) to answer questions from students at Allentown, at The call took place at 12:20 pm Eastern Time this Thursday, February 5, 2026, and is shown on the Learn With NASA YouTube channel.
The event is organized by Da Vinci Science Center and aimed at primary to secondary school students, as well as members of the local community. Essa initiative seeks to stimulate interest in areas of science, technology, engineering and mathematics, known as STEM.
The interaction highlights the work routine on the ISS and the challenges of life in space, promoting scientific education among young people.
Educational event details
The broadcast lasts about 20 minutes and includes pre-recorded questions submitted by students. Chris Williams covers topics such as scientific experiments carried out in microgravity and the daily maintenance of the orbital station.
Da Vinci Science Center prepares the venue to receive in-person participants, while the general public follows online. Essa combination allows for broad reach and encourages the participation of schools from different regions.
These educational calls have occurred regularly since the start of continuous operations on the ISS. Elas have connected thousands of students to astronauts in orbit over the years.
Profile of Chris Williams
Chris Williams joins Expedição 74 as a flight engineer and carries out his first long-duration space mission. Selecionado by NASA in 2021, he completed intensive training and launched in November 2025 aboard the Soyuz MS-28.
A physics graduate with a PhD from MIT, Williams previously worked as a radio astronomer at Laboratório of Pesquisa Naval in the USA. Sua experience includes research in human health and technologies for deep missions.
On the ISS, he conducts equipment maintenance and biomedical experiments. Recentemente, recorded images of the Artemis II capsule on the launch pad at Flórida.
Importance of downlinks for STEM education
Educational downlinks allow students to ask direct questions of professionals in the space. Essa proximity motivates careers in technical and scientific areas.
NASA hosts dozens of these events annually with partner institutions in the Estados Unidos. Eles reach millions of views online and inspire school projects related to space exploration.
- Stimulate curiosity about microgravity and its effects on the human body;
- Demonstrate practical applications of mathematics and engineering;
- They show the diversity of professions in the space agency;
- They connect the classroom to real research in orbit.
Everyday life at Estação Espacial Internacional
The ISS has been home to international crews for over 25 years in continuous occupation. Astronautas dedicate time to mandatory physical exercises to combat bone and muscle loss.
Maintenance of systems such as water recycling and oxygen generation occupies a significant part of the routine. Williams and colleagues also conduct spacewalks for external repairs when necessary.
Communication with the control at Houston occurs 24 hours a day via the SCaN network. Esses contacts include technical updates and family calls.
