While the US is best known for its space launch systems, the UK has strong reputation for developing sensors and systems that are extremely capable as well as lower cost compared to revivals.
Tim Just, head of space at Innovate UK said: "All of these burgeoning firms are at the forefront of the new space race and have genuinely built innovative solutions to some of the sector's greatest challenges."
All of the companies on the mission have developed unique business models and approaches, which dramatically lower the cost of space technology, research and analysis. In addition, the US private space sector has rapidly expanded over the last twenty years and affords an excellent opportunity for UK companies to build connections with industry leaders there.
The 2010 strategy sets a target to grow the UK's share of the world's space economy from 6.5% to 10% by 2030. By today's estimates this would lead to a UK sector with £40 billion per annum of space-enabled turnover and the creation of 100,000 new jobs.
Jo Johnson, Minister for Universities and Science, said: "The Space sector is one of Britain's great success stories.This mission will help the brightest and best of British firms showcase their innovate products and expand into new markets."
It is packed agenda for those attending, which will attend meetings with some of the biggest names in the sector including Nasa, Lockheed Martin and Virgin Galactic.
