Virgin Orbit Holdings Inc., the spaceflight company founded by British billionaire Richard Branson, is set to make history tonight with the launch of Britain's first-ever space mission. The mission, set to lift off from Spaceport Cornwall in Newquay, England between 9:40 p.m. and 11 p.m. tonight, will involve a modified Boeing Co. 747 jetliner carrying a rocket under its wing. The mission was initially delayed due to adverse weather conditions, but final preparations are now going ahead as planned. The mission will be the first of its kind for the UK, and will mark a major milestone for Virgin Orbit, which has been working towards launching its own space mission for several years. The mission is expected to be a significant event for the UK space industry, and will be watched by space enthusiasts and industry professionals alike. Virgin Orbit has not yet revealed the specifics of the mission, but it is expected to involve a number of experiments and tests, which could pave the way for the company's future space operations. The mission will be a major step towards the UK's goal of becoming a major player in the commercial space industry, and could open the door to a wide range of new possibilities for the country.
