Two miniature satellites will open the door to era of British espionage from space 


Two ‘cereal box-sized’ satellites set to be launched from Cornwall this summer could provide Britain with its own spying capability from space.

The UK currently relies on imagery from RAF aircraft, as well as the US Department of Defence sharing its data, to monitor things like Russian troop movements on the battlefields of Ukraine.

But officials want to create a constellation of small intelligence, surveillance and reconnaissance (ISR) satellites, so that the country is not so dependent on other nations.

The mini cube-shaped satellites (‘cubesats’) will be blasted into space on a Virgin Orbit rocket called LauncherOne, which itself will be unleashed from a jumbo jet from Spaceport Cornwall, part of Newquay Airport.

HOW VIRGIN ORBIT GETS SATELLITES INTO SPACE 

TAKE OFF Cosmic Girl, an adapted Boeing 747, takes off from an air and space port, initially in California.

ROCKET DEPLOYMENT  At cruising altitude around 35,000 feet, the chief pilot hits the Big Red Button that releases the rocket from the pylon. 

FIRST STAGE BURN After a 4-second freefall, the first stage engine, NewtonThree, bursts to life, accelerating the rocket to more than 8,000 miles per hour. Once its fuel is spent, the first stage detaches.

FAIRING SEPARATION With LauncherOne now between 310 to 745 miles above the Earth’s surface, the fairing pops open, exposing the payload as it nears its destination. 

SATELLITE DEPLOYMENT Finally, with very precise timing, the second stage ejects the satellite into its final orbit. 

RETURN TO EARTH Atmospheric drag will eventually pull the second stage back down to Earth, where it burns up in the atmosphere, minimising environmental footprint.

Once deployed, the cubesats will deliver high-tech imaging sensors, allowing the Ministry of Defence (MoD) to monitor Earth and its oceans. 

They will also be able to monitor radio signals, a capability that has been vital in intercepting conversations between Russian commanders and junior ranks.

The satellites, which are part of the MoD’s so-called ‘Prometheus-2’ mission, are prototypes and will carry out an initial testing exercise to see what is possible for Britain in the future.

Weighing 20 pounds and measuring about 12 inches long, 8 inches wide and 4 inches deep, they will operate in low Earth Orbit, around 340 miles above the Earth and 30-60 miles apart at 17,000mph.

‘Cubesat 1’ and ‘Cubesat 2’ will provide a test platform for monitoring radio signals including GPS and sophisticated imaging.

Cubesat 1 includes a laser detector, a GPS receiver and a hyperspectral imager – which can capture multiple slivers of pictures over different wavelengths of light.

Cubesat 2, meanwhile, includes two optical imaging cameras, a laser range finder, and a GPS receiver. 

One camera will be fitted with a wide-angle lens for a 180-degree view of Earth’s surface, with the second camera observing the other Cubesat 1 to support space situational awareness and monitor other objects orbiting the Earth.

Built by In-Space Missions Ltd, based in Hampshire, and designed with Airbus Defence and Space, Prometheus-2 is a collaboration between the MoD and international partners, including the US National Reconnaissance Office (NRO).

‘Space technology is crucial for developing Defence capabilities,’ Defence Procurement Minister Jeremy Quin has previously said.

‘The launch of Prometheus-2 represents another important step forward for our homegrown space programme.

‘This collaboration with In-Space Missions and Airbus paves the way for the UK to become a more resilient, more robust and more significant global space entity.’

The satellites, which are set to launch at an estimated cost of $300,000 (£246,000), will be just one of the payloads aboard LauncherOne when it blasts off from Spaceport Cornwall some time this summer.

If successful, it will earn the title of the first satellite launch from British soil. 

The upcoming launch will involve Virgin Orbit’s carrier aircraft, a modified Boeing 747 called Cosmic Girl, and LauncherOne, a two-stage orbital launch vehicle, tucked into Cosmic Girl’s belly.

Once Cosmic Girl is at a high enough altitude – around 35,000 feet – LauncherOne is unleashed.

When at an orbital altitude, LauncherOne deploys the satellites, which will be catapulted into orbit at 8,000 miles per hour.

Virgin Orbit has already conducted three successful consecutive orbital missions with LauncherOne in 2021 and 2022, the last one in January.

However, all three took place from Mojave Air and Space Port, California, so the first one from UK soil is generating considerable interest. 

Over the last 16 months since January 2021, LauncherOne has already deployed payloads in space for Virgin Orbit’s customers, including NASA and the US Department of Defense.

WHAT ARE CUBESATS?

A CubeSat is a miniature satellite that has been sent into space.  

Nasa defines them as a class of nanosatellites that use a standard size and form factor.

Each unit, or U, is 10cm x 10cm x 10cm (4 in x 4 in x 4 in) and the cubes can be pieced together to create larger structures. 

These can include 1.5, 2, 3, 6, and even 12U objects. 

They are often made of commercial off the shelf products and are a low-cost option for space exploration. 

CubeSatS have a variety of functions. The small satellites are intended for low Earth orbit (LEO) where they perform a number of scientific research functions and explore new space technologies. 

They were originally developed to teach university students about satellites, CubeSats are now a major commercial technology, providing data on everything from shipping routes to environmental changes.

Each unit, or U, is 10cm x 10cm x 10cm (4 in x 4 in x 4 in) and the cubes can be pieced together to create larger structures. These can include 1.5, 2, 3, 6, and even 12U objects
