Goonhilly goes deep space

Paris (ESA) Feb 23, 2018
Until now, if you're an entrepreneur planning future missions beyond Earth, you'd have to ask a big space agency to borrow their deep-space antennas. Now, thanks to the UK's county of Cornwall and ESA, you'll have a commercial option, too.
If you're planning on flying a robotic or even human mission in the near future to the Moon, an asteroid or even Mars, one indispensable requirement you'll face is the need for at least one deep-space tracking dish to communicate with your craft.
Today, however, there's no commercial deep-space service available to rent for your specific mission needs - and building a new station from scratch all on your own is rather pricey.
Exploration mission needs growing
Later this year, they will add the new BepiColombo mission to Mercury and, in the near future, ESA's Solar Orbiter, Euclid and Cheops.
"The amount of science data flowing in from ESA's current missions, not to mention from future missions with improved instruments, is growing strongly," says ESA's Pier Bargellini, responsible for network operations.
"By the middle of the next decade, ESA's deep-space communication needs for supporting today's missions, like ExoMars, and upcoming spacecraft, like Juice, is expected to exceed our present capacity by around half.
"We are considering urgently how to bridge this gap."
Developing commercial capacity
Under the project, a 32 m-diameter dish built in 1985 will be upgraded to provide fast data links for missions far beyond Earth - typically exceeding 2 million km.
The project will be initially funded through a Euro 9.5 million investment from the UK's Cornwall and Isles of Scilly Local Enterprise Partnership, a public - private regional economic development body, and will later include a smaller investment from ESA.
"Once the station upgrade work is complete, in about 24 months, Goonhilly will be able to complement ESA's own stations, and provide deep-space tracking for the Agency's missions as well as those of other space agencies or from private space start-ups aiming to exploit the Moon or mine asteroids," notes Klaus-Jurgen Schulz, responsible of ESA ground station engineering.
Goonhilly, established in 1962 and at one time the largest satellite station in the world, with over 60 dishes of varying size, is well known in the UK. Its antennas have brought iconic images to UK TV viewers, including Muhammad Ali fights, the Olympic Games, the Apollo 11 Moon landing and 1985's Live Aid concert.
"Upgrading Goonhilly and building up a commercial capability to support future exploration missions is good for ESA and good for European science and industry," says Rolf Densing, ESA's Director of Operations.
"It's also excellent value for European taxpayers."
Airbus and human spaceflight: from Spacelab to Orion
Noordwijk, Netherlands (SPX) Feb 13, 2018
Thirty-four years ago, Spacelab was placed in orbit, paving the way for Europe's human spaceflight programme. It began a legacy of pioneering technology that includes the ATVs, Columbus and the Orion European Service Module. Spacelab's launch on 28 November 1983 was the first of 22 Spacelab missions involving cutting-edge scientific experiments in fields such as new materials, processing of pharmaceutical products and astronomical observation. An industrial consortium headed by MBB-Erno, one of th ... read more
