Monitoring the constantly changing shape of the sea surface is important for scientific and societal applications such as ocean current forecasting, climate research, ship routing, cable laying, and debris tracking.
A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely. The project was based on an idea submitted by the Institute for Space Studies of Catalonia (IEEC) through the Open Space Innovation Platform (OSIP) – ESA’s place for your space ideas.
The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of
Settle the TRAPPIST exoplanets: challenge for evolutionary computing
Tuesday, 22 March 2022 10:04
It reads like a work of science fiction: software that mates, reproduces and mutates being deployed to plan the exploration and settlement of the exotic TRAPPIST-1 solar system, around 40 light years away from Earth. In fact this is the latest competition conceived by ESA’s Advanced Concepts Team, this time seeking to challenge the worldwide evolutionary computing community.
Space-grown lettuce could help astronauts avoid bone loss
Tuesday, 22 March 2022 08:00
NASA is preparing to send humans to Mars sometime in the 2030s. The 3-year mission will expose astronauts to a long period of microgravity, which will cause them to lose bone mass. But now, scientists report transgenic lettuce that produces a bone-stimulating hormone. Someday, astronauts could grow the lettuce in space and help guard against bone loss—simply by eating a big bowl of salad. In addition, the lettuce might help stave off osteoporosis in resource-limited areas here on Earth, the researchers say.
The researchers will present their results today at the spring meeting of the American Chemical Society (ACS).
Previous studies of astronauts on extended space missions have shown that they lose, on average, more than 1% of bone mass per month spent in space, a condition known as osteopenia.
