Testing Galileo for space
Video: 00:06:36
Galileo has grown to become Europe’s single largest satellite constellation, and the world’s most accurate satellite navigation system, delivering metre-level positioning to more than 3.5 billion users around the globe.
It all began at ESTEC’s Test Centre, Europe’s largest satellite testing facility. This is where the very first positioning fix took place in March 2013, after the launch into orbit of the initial four IOV satellites. Following that, all 34 Galileo Full Operational Capability satellites also passed by ESTEC for their pre-flight testing.
This 3000 sq. m environmentally-controlled complex, operated and managed by European Test Services for ESA, hosts an array of test equipment able to simulate all aspects of spaceflight, from the noise and vibration of launch to the vacuum and temperature extremes of Earth orbit.
The production line at manufacturer OHB in Germany completed one new satellite every six weeks. After integration each satellite was then shipped to the ESTEC Test Centre for a three-month test campaign, after which it would be accepted by the Agency and declared ready for flight. Some facilities have had to be adapted specifically for Galileo, and the ESTEC Test Centre had to institute new security protocols because this was the first time that satellites with security restrictions were being tested at the site.
Today there are 28 of these Galileo First Generation satellites in service, with 10 more due to be launched in the next years. Upgraded Galileo Second Generation satellites are under development and will follow them into orbit later this decade.
Members of ESA’s Galileo team and ETS look back on this massive testing effort that established Galileo was ready for space.

The International Space Station Gets a Clean Bill of Health. Despite a Few Opportunistic Microbes, the Station is “Safe” for Astronauts
In a recent study published in Microbiome, a team of researchers led by NASA’s Jet Propulsion Laboratory conducted a five-year first-of-its-kind study investigating the microbiome (environmental profile) of the International Space Station (ISS). The purpose of the study was to address “the introduction and proliferation of potentially harmful microorganisms into the microbial communities of piloted spaceflight and how this could affect human health”, according to the paper.

NASA’s new Glider Could Turn any Airport Into a Spaceport
Getting to space has almost always been a multi-stage process. Those stages typically took the form of different stages of chemical rockets, but it doesn’t have to be that way. Plenty of alternative options have been proposed, and one that NASA has been working on for almost a decade is getting closer to commercialization. The project, known as the Towed-Glider Air Launch System (TGALS), uses three very different stages – a business jet, and glider, and two separate rockets – sort of. But its main advantage means that any airport large enough to host a business jet could also become a spaceport.
Navigation Satellites fly at 23,000 km Altitude. Europe Wants to Build a Constellation That Flies Much, Much Lower
Distances to different orbits can be hard to understand. For example, the ISS sits around 400 kilometers from Earth, whereas some satellites, such as Starlink, orbit at about 550 km. Often that is intentional, as objects in those orbits will eventually degrade their orbit and burn up in Earth’s atmosphere. However, many systems orbit a few orders of magnitude higher – such as the Galileo satellites that make up the backbone of the European Union’s satellite navigation network. At an orbit of around 23000 km, it has some advantages over lower-hanging satellites but also plenty of disadvantages too. Now, the EU was to eliminate some of those disadvantages by releasing a whole new set of lower-orbiting satnav satellites.
