In-Space Missions Limited are world class experts who design, build and operate physical and digital customer missions, providing a valuable service to global customers keen to get their technology on orbit quickly.

Based in Alton, UK, our experienced staff work with a new space approach which enables a significant reduction in traditional timescales.

A 3D model of the Faraday Pheonix small sat including cube satellite hosted payloads - In-Space Mission

From our dedicated HQ site in Alton, Hampshire in the UK with purpose built, satellite cleanrooms, we design manufacture, integrate and test a range of small satellites from 50kg to 300kg. We work closely with our customers to develop payload and / or full mission solutions and then lead the process to realise them on orbit.

Depending on the customer’s needs we can support as much of the cycle as needed including payload development support; integration of payloads into the spacecraft; system testing; licensing; launch; commissioning; on-orbit operations; and secure data delivery. We also have options for additional training, consultancy and procurement support as needed.

In-Space Missions has taken the decision not to be vertically integrated, as many other small satellite providers are, and to collaborate closely with other small satellite subsystem suppliers instead.  This novel supply-chain approach allows In-Space to promote a “best in breed” approach to subsystem selection and investigate the use of a range of subsystems to provide maximum technological benefit to our customers or a market advantage. We also engage with the wider SME community, Space South Central hub and several Universities including Cranfield, Southampton, Surrey and Birmingham to ensure emerging technologies are on our radar.

Alongside our parent company, BAE Systems, we have committed to achieving Net Zero (Scope 1 and 2) emissions by 2030 and are working towards a UK net zero value chain by 2050. We have a published a Carbon Reduction Plan thus publicly declaring our net zero ambitions.

Meet the Leadership team

The In-Space team have over 150 combined team-years of experience in military, institutional and commercial space activities covering Earth Observation, Sat Comms, Navigation, Space Science and Space Exploration. Our expertise spans developing missions, employing spacecraft from 3kg to 3000kg covering the full range of activities from concept and business case development, through to bidding and winning the work, to delivering and operating the system.

Doug Liddle

Chief Executive Officer & Co-Founder

After leaving Oxford in 1993 with an MA in Physics, Doug joined the Defence Research Agency (now QinetiQ) to work on all things space, including radar surveillance, space radiation, spacecraft dynamics and military communications systems.

In 2001, Doug moved to Surrey Satellites to become a spacecraft systems engineer. Over the following years, he developed several new spacecraft including Europe’s first Galileo demonstrator satellite, GIOVE-A; ran the Science and Exploration business unit; and delivered multiple satellites and optical imaging payloads including the UK’s first cubesat.

In 2015, Doug created In-Space Missions, a company founded to develop new space enabled services and offer expert consultancy to industry, academia and government. Since 2015, Doug has variously run the UK’s rocket programme; led the technical development of a disruptive innovation centre; developed a commercial demonstration platform for space; and initiated a company delivering real time video and immersive experiences from space. Doug also sits on a number of industry advisory boards and takes an active interest in STEAM outreach.
