Yes, specially designed glass can work in space.
While typical window glass wouldn't survive the harsh conditions of space, specialized glass formulations are engineered to withstand extreme temperatures and radiation.
Here's a breakdown:
-
Extreme Temperatures: Space presents two thermal challenges: intense cold (around 3 Kelvin in shadowed areas) and extreme heat from solar radiation. The glass used in spacecraft windows is formulated to resist cracking or deformation under these conditions.
-
Radiation Shielding: Space is permeated with high-energy particles. The glass is designed to provide some shielding against radiation, protecting astronauts and sensitive equipment.
-
Strength and Durability: Spacecraft windows undergo rigorous testing to ensure they can withstand the pressure differentials between the inside of the spacecraft and the vacuum of space. They must also be durable enough to survive the vibrations and stresses of launch and reentry.

Examples:
- The Space Shuttle windows were made of multiple layers of glass to provide both thermal and impact protection.
- The International Space Station (ISS) cupola, a panoramic observation module, utilizes specialized glass windows to allow astronauts to view Earth and conduct experiments.
Essentially, the success of glass in space relies on advanced materials science and engineering, resulting in glass compositions far removed from everyday use.
