Q. Which country attempted ‘Start Me Up’ mission, its first orbital space launch?
Answer:
UK
Notes: The UK attempted its first orbital space launch from UK soil, making it the privately-owned Virgin Orbit's first international launch.
The repurposed Virgin Atlantic Boeing 747 aircraft, named ‘Cosmic Girl’ took off from Cornwall, UK. However, the mission dubbed ‘Start Me Up’ failed due to an anomaly in a satellite launch. The rocket was carrying nine small satellites.
