The launch window for Space Concordia’s Starsailor rocket suborbital launch is open, however the current weather is preventing a launch attempt.
Weather in the Mistassini area currently includes rain showers today and tomorrow during the launch window, with a possibility of thunderstorms.
A source reports to SpaceQ that the likeliest earliest launch attempt could be Sunday, August 10 when the weather improves. The weather window currently looks good between Aug. 10-12.
The Space Concordia team was able, according to our source, perform “a critical pre-launch cryo test” Thursday night.
Stay tuned for updates as they come in.
