Varda Space launches three capsules to grow cancer drugs in orbit
California-based Varda Space Industries launched three spacecraft into Earth's orbit on October 1 and October 20 to test drug manufacturing and re-entry systems.
Simultaneous capsule launches begin
The company successfully placed three washing machine-sized capsules into orbit for the first time. Two vehicles launched on October 1, followed by a third launch on October 20. This record achievement marks a significant step toward operating a fleet of orbiting pharmaceutical factories.
Microgravity aids crystal growth
One capsule contains tiny crystals of a potential cancer drug being grown in weightlessness. On Earth, gravity causes particles to settle and density differences create currents that interfere with crystal formation. Removing these effects allows for better growth conditions inside the spacecraft.
Other tests accompany drug trials
The remaining capsules are testing heat protection materials and navigation systems for atmospheric re-entry. These vehicles will plunge back through Earth's atmosphere at hypersonic speeds during their return journey. The data gathered supports the future goal of manufacturing various products in space.
