Remembering every month important events and dates of scientific ballooning history

In this edition:

  • GUSTO telescope finally lands in Antarctica
  • First balloon missions of the year by World View
  • Aerostar: NSC acquisition and Thunderhead flights
  • Chinese balloons back in the news, this time for real
  • In brief: SuperBIT, Iwaya, NASA Flight Opportunities, SCopEX, Balomania

World Balloon News is a somewhat regular bulletin containing balloon-related news of what's going on in the field, some speculation (fancy term for "insider data" from sources I can't reveal), historical images, and details about the new contents that week after week enrich this humble project.

Weekly Balloon News # 11 - Chinese balloon edition - March 4th, 2023

Contents:

  • What kind of balloon it was?
  • Not an isolated incident, and not a "fleet" of spy balloons.
  • Previous sightings. Connecting the dots
  • The first downing using missiles? Yes and No
  • The "secret" Chinese balloon base
  • Science on the edge of reality
  • The "weather balloon" explanation 70 years later
