*Recurring Martian Streaks could be just sand rather than water
A new study claims dark streaks often seen on the Sun facing slopes of Martian gullies and ravines could be caused by moving sand rather than melting sub surface permafrost. The conclusions provide an alternative to previous speculation that the features – known as recurring slope lineae or RSLs – were caused by flowing meltwater from permafrost layers seeping out from the sides of gullies and ravines.
*Could cosmic dust be transporting life between worlds?
A new study suggests that life on Earth might have originated from biological particles brought to the planet in streams of cosmic dust particles. The findings would mean fast-moving flows of interplanetary dust that continually bombard Earth’s atmosphere could deliver tiny organisms from far-off worlds, or send Earth-based organisms to other planets, according to the research.
*Listening for alien signals.
Way back on August the 15tjh 1977 astronomers at Ohio State University’s Big Ear radio telescope supporting the SETI Search for ExtraTerrestrial Intelligence picked up a strange and very strong narrow band radio signal coming from the direction of the constellation Sagittarius. Now a new campaign is underway to listen for alien signals – not from Sagittarius but from M-31 Andromeda.
*NASA Launches NOAA Weather Satellite to Improve Forecasts
The penultimate launch of a Delta II rocket has successfully placed the first of a new generation of advanced weather satellites into a Sun synchronous orbit. The Joint Polar Satellite System-1 or JPSS-1 blasted into deep black early morning skies from the Vandenberg Air Force base in California.
*Maxus-9 provides a little microgravity
The European Space Agency has launched a Maxus sounding rocket to see how microgravity effects microorganisms. The mission which blasted off from Sweden’s Esrange Space Center-- flew on a sub-orbital ballistic trajectory delivering its five onboard experiments to the edge of space.
