Launch times draw near for Aalto satellites
By Jaan Praks – The Aalto-2 satellite, designed and built by students, is ready and waiting to be launched inside the Cygnus space shuttle at the Cape Canaveral Space Launch Complex in the US.

On 22 March, the shuttle will be launched with an Atlas V booster rocket up to the orbiting international space station, where the astronauts will release it later to orbit independently.

Aalto-2 will take part in the international QB50 Mission, the aim of which is to produce the first ever comprehensive model of the features of the thermosphere, the layer between the Earth’s atmosphere and space. Dozens of satellites constructed in different countries will also be part of the mission.

Construction of the Aalto-2 satellite began in 2012 as a doctoral project when the first students graduated as Masters of Science in Technology after working on the Aalto-1 project.

Since the start of the Aalto-1 project in 2010 and the Aalto-2 project two years later, around a hundred new professionals have been trained in the space sector. The impact is already visible in the growth of space sector start-up companies. more> https://goo.gl/yKLrez

A new method for converting wastewater nutrients into fertilizer
By Riku Vahala – Researchers of Aalto University have developed a new, energy-efficient method for capturing nitrogen and phosphorus from different liquid waste fractions. In laboratory studies, with the help of the method, it is possible to separate 99% of the nitrogen and 90-99% of phosphorus in wastewater and produce granular ammonium sulphate (NH4)2SO4 and phosphorus precipitate suitable for fertilizers.

The capture method is based on the use of calcium hydroxide Ca(OH)2 to convert ammoniacal nitrogen NH4+ into ammoniacal gas NH3, which are separated through a semi-permeable membrane. Following this, the ammonium is dissolved into sulphuric acid to produce ammonium sulphate. In the process, the phosphorus is precipitated with the help of calcium salt.

‘A patent application for the method is currently under way, and the aim of the project is to find company partners who could make use of the patent in the best possible manner, create products with its help and market the new process. If successful, the new process will also create a competitive export product’, Anna Mikola, DSc (Tech), points out. more> https://goo.gl/kOrqHP

Society needs critical and informed thinkers
By Tuula Teeri – Universities exist first and foremost in order to educate critical thinkers who are equipped with the confidence and the boldness to defend the knowledge society. Society needs critical, informed thinkers in all sectors of society, perhaps now more than ever: “Universities have a huge responsibility in safeguarding the knowledge society, developing new knowledge and insistently advocating for knowledge-based decision making.”

Milja Asikainen added: “Universities should take a bigger role in leading public discussions, not just adapting to them.”

Aalto University is performing well in creating added value from research and education, citing the development of the Aalto innovation ecosystem. Over half of all the start-ups coming out of Finnish universities originate from Aalto. more> https://goo.gl/ItZXvp

Healthy communities through good planning
By Timo Hämäläinen – SoftGIS was introduced ten years ago and about one hundred municipalities in Finland and about twenty countries across the world have started to use it.

SoftGIS is a method in which people are asked about their experiences about the environment through the internet. Location data will automatically be linked with this information, which makes it possible to pose various questions important from the point of view of urban and community planning.

A considerable change has taken place in urban and community planning in a short space of time. SoftGIS enables us to discover people’s opinions – also those of the passive majority – significantly better than before. Earlier, we had to settle with the opinions that were obtained from the most active people and from residents’ associations.

SoftGIS was used in drawing up the new master plan for Helsinki, published at the end of 2015. Helsinki residents where asked where they thought the city should under no circumstances build anything, and where they thought something could be built. more> http://goo.gl/W9XLqn
