Join us on Monday 15 June for a live streamed conversation with European experts on how to reinvent your business model.
Europe’s next Vega launch will premiere a new dispenser called the Small Spacecraft Mission Service, or SSMS. It will transport more than 50 satellites at once into orbit on the first rideshare mission dedicated to light satellites. Liftoff from Europe’s Spaceport in French Guiana is set for next week.
Replay of conversation with European experts on how space can help with working remotely and efficiently, recorded on 9 June 2020.
The coronavirus pandemic has accelerated the digital transformation process. To contain the spread of the virus, governments across Europe decided to keep workers at home.
Those who can work from home have engaged in what can be seen as a large experiment for the remote work system. Digital media platforms have enabled these workers to participate in online meetings and discussions, and to collaborate using shared resources.
Guests reflected on new working approaches, working efficiently, balancing work with family and social life, lessons learned so far from the COVID-19 lockdown and how space can support smart working solutions.

The Foam-Coarsening experiment ran a new batch of cartridges in the Fluid Sciences Laboratory of the European Columbus module.
The experiment began in April to study foams in depth under the more stable conditions afforded by microgravity on the International Space Station.
The cell cartridges contain a mixture of soap and water. Bubbles are generated by moving a piston at high speed. The foam is observed for up to 100 hours, during which the foam bubbles become larger but less in number. This process slows down over time so measurements are stopped when five bubbles are formed in each cell section. The results are analysed with laser optics and high-resolution cameras.
The new batch contains the same water and soap mixture but with a difference in the amount of liquid in the cell. Producing foams in a different concentration allows researchers to study how the bubbles enlarge (or coarsen).
What is so special about foam? Besides appearing in your food and drink, foams are also found in sealing products, cosmetics and personal hygiene products, and even construction. They are lighter, offer better insulation and can be just as strong as compact materials.
Observing foams on Earth is tricky because the mixture of gas and liquid that makes up a foam quickly starts to change. Gravity pulls the liquid between the bubbles downwards, and the small bubbles shrink while the larger ones tend to grow at the expense of others. Due to drainage, coarsening (or enlarging) and rupture of the bubbles, a foam starts to collapse back to a liquid state.
But in space foams are more stable because the liquid does not drain in weightlessness. This allows scientists to study the phenomena of a bubble slowly becoming bigger and bursting, which on Earth are masked by the drainage that destabilises the foam.
Deeper insights into the behaviour of foams makes for better applications of its use on Earth. Besides improving food production, foams can also be metallic and have incredible structural characteristics. Aluminium foam, for example, is as strong as pure metal but much lighter. This research can help in the construction of light-weight and sturdy aerospace structures and new shielding systems for diagnostic radiology equipment in hospitals.
Read more about the life of a foam and the lessons learned from research so far.
The Foam-Coarsening experiment was developed by Airbus for ESA. The experiment is controlled and data collected by the Belgian User Operations Centre in Brussels, Belgium.
ESA and the United Nations Office for Outer Space Affairs have selected a team from Mahidol University, Thailand to carry out research using ESA’s hypergravity-generating Large Diameter Centrifuge. The team will see how watermeal – the smallest flowering plant on Earth, even smaller than the more familiar duckweed – responds to changing gravity levels to assess its usefulness for space-based life support systems.
A deployable laboratory that can test frontline healthcare staff, civil protection volunteers and police forces for the coronavirus has left Belgium and is on its way to Piedmont, Italy.
Italy has been badly affected by the pandemic. In response ESA has been working to identify how space can help.
Did you know that in microgravity you can better study the boiling process?
Boiling is a very common process in our everyday life. For instance, we usually boil water to cook or to clean. The boiling process is common in many engineering fields such as environmental applications and industrial chemical processes.
Understanding the dynamics of boiling is essential to improve energy production and conversion in power plants, and to design future space applications like cryogenic fuel storage and propulsion.
On Earth the process happens too fast to be accurately observed and measured. But experiments conducted in low gravity environments, like on the International Space Station, allow us to observe phenomena like phase transition and the onset of bubbles much more clearly.
Such studies may lead to increase the energy efficiency of several application also here on Earth, from Power plants to thermal management systems used in electric vehicles, laptops, and smartphones just to cite a few examples.
This video interviews Peter Stephan of the Technical University of Darmstadt in Germany talking about the Reference mUltiscale Boiling Investigation experiment, known affectionately as Rubi. Paolo Di Marco of the University of Pisa in Italy talks about applying an electric field on the boiling process in microgravity and Catherine Colin from the Institut de Mécanique des Fluides de Toulouse in France talks about heat transfer flow boiling and how to keep electronics cool. Lastly Giuseppe Zummo, of Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development, ENEA, explains how parabolic flights are used to test new two-phase flow heat transfer in weightlessness.
Do take advantage of the opportunities and capabilities that are available for your research and development to further grow and extend your achievements. Take the next step... the step to Space. We did it already.
The coronavirus pandemic has brought the tourism and travel industry to a near-standstill, with nationwide lockdowns significantly impacting the aviation and maritime industry worldwide. Satellite images, captured by the Copernicus Sentinel-2 mission, show parked aircraft and anchored vessels in times of COVID-19.

Join us on Tuesday 9 June for a live streamed conversation with European experts on how space can help with working remotely and efficiently.
The coronavirus pandemic constitutes an unprecedented challenge with severe societal and socio-economic consequences. In order to shed new light on these changes taking place, ESA and the European Commission have worked closely together to create the ‘Rapid Action Coronavirus Earth observation’ dashboard – also known as RACE. The platform, which was unveiled today during an online event, uses Earth observation satellite data to measure the impact of the coronavirus lockdown and monitor post-lockdown recovery.
