For over twenty years now, there has been continuous human occupation off our planet.

The International Space Station (ISS), launched in 1998, is a modular satellite in low orbit around the Earth, which is visible even with the naked eye.

In October, NASA launched an Antares rocket carrying a Cygnus resupply ship. This cargo ship carried an experimental system on board used to study the oxidation of ammonia under microgravity conditions to convert urine into water on the ISS. Improving this waste management system has far-reaching repercussions for longer exploratory missions where the weight of the payload must be optimized with the amount of water needed (which is heavy) to sustain life during the trip. Given the limited resources aboard a spaceship, the recovery of water from all processes is of great importance. (more…)

Recent growth in space-related activities has presented numerous opportunities for electrochemistry in space. That’s why Greg Jackson, chair of the ECS High-Temperature Energy, Materials & Processes Division (H-TEMP) and mechanical engineering professor at the Colorado School of Mines, took it upon himself to bring the first-ever symposium dedicated to “Electrochemistry in Space” to the 236th ECS Meeting.

“As a board member and someone who cares about the Society expanding its audience, I felt that there are many activities going on in regards to applying electrochemistry in space and the uniqueness of the space environment merited a special symposium,” said Jackson, lead symposium organizer.

The potential for increased lunar and Martian activities with in situ resource utilization (ISRU), human space flight, and in-space satellite maintenance, and space debris management present many technical challenges and opportunities where electrochemistry plays a central role. (more…)

The new study also opens the door to identifying other molecules floating in space.

Buckyballs—or buckminsterfullerenes, named for their structural similarities to the designs of Buckminster Fuller—have just answered the 100-year-old question of odd variations in light coming through interstellar space.

Astronomers once assumed that this cosmic-light was the result of dust or other tiny space detritus, but a team of chemists have now determined that it is actually the result of buckyballs floating around in space.

Though this isn’t the first time that buckyballs were found in far-off locations. In 2010, researchers spotted the first ever buckyballs in space using the Spitzer telescope.

Listen as some of the world-leading scientists in nanocarbon and fullerene research discuss the monumental role buckyballs have played in science.

However, the spotting in 2010 proved that buckyballs can indeed exist in space, whereas the current buckyball spotting solve a nearly century-long question that has troubled astronomers globally.

Until now, the motor and the inverter, which converts the battery’s direct current into alternating current for the motor, were two separate components.

A team of engineers at Siemens’ has developed a way to save space, reduce weight, and cut the cost of electric car production. The team’s solution revolves around integrating an electric car’s motor and inverter, which have always been two separate components prior to this development.

This from Siemens:

The solution’s key feature is the use of a common cooling system for both components. This ensures that the inverter’s power electronics don’t get too hot despite their proximity to the electric motor, and so prevents any reduction in output or service life.

Accordingly, the weight of the vehicle is reduced due the integration of the inverter into the motor, which will now only need a single housing. Additionally, the development produces added installation space that can be used for a charging unit.
