A SpaceX Falcon 9 rocket and its payload—a communications satellite backed by Facebook—were destroyed this morning during launch tests at Cape Canaveral, Fla. No-one was hurt in the explosion. Read the rest
Cameras on the International Space Station captured this footage of three major hurricanes on Earth on August 30. Two of these storms are in the Pacific Ocean, and one is in the Atlantic Ocean. Read the rest
An update on the Juno mission, from NASA.
An update on the Voyager exploration program of Saturn from NASA's Jet Propulsion Laboratory in Pasadena, California.
Randy L. Korotev from the Washington U in St Louis Department of Earth and Planetary Sciences presents this handy flowchart (based on this one by Deborah Guedes) for deflating your excitement at having found rock that may be a meteorite but almost certainly isn't. Today's XKCD offers a handy abridgment if you find this one excessive. Read the rest
In interstellar terms, it couldn't be closer: an Earth-like world orbiting Proxima Centauri, the closest sun to our own. Moreover, it's in the system's habitable zone, raising the possibility of liquid water and the conditions to sustain life. But don't get too excited...
Although media reports say the rumored planet orbits in a region that’s potentially favorable for life, these smaller stars are less stable, and Proxima Centauri is known to have violent flares at times. Its occasional tantrums have made astronomers skeptical of finding life around red dwarf stars in the past.
However, skepticism has softened some in recent years, and SETI recently launched a major initiative to search for life around 20,000 red dwarfs, as these stars are the most common in the Milky Way galaxy.
One of the most popular locations in science fiction, a habitable world at Proxima Centauri (or, rather, a generation ship headed for it) was most recently tackled in Ascension.

Though 1967's Outer Space Treaty says no country can lay claim to the moon (and thus no person can get a deed to lunar territory), the treaty does allow for commercial and scientific installations on Luna, and there are some very small, very valuable bits of crater rim that could be squatted in this way, to the enormous benefit of whomever gets there first (and the detriment of all others).

The HiRise imager in orbit around Mars shoots a continuous stream of data about its surface our way. Nasa's posted 44,000 images so far, each available in all sorts of formats and projections. You could have one a day as your desktop background and never run out.
This is cool as hell. “While thousands turned out to watch NASA’s Space Launch System (SLS) recently complete a full-scale test of its booster, few were aware of the other major test occurring simultaneously.” NASA’s High Dynamic Range Stereo X (HiDyRS-X) camera project captured the test like we've never seen before, and recorded propulsion video data in unprecedented detail.
One million miles from Earth, hanging in space between Earth's gravitational pull and the sun's, is the DSCOVR satellite and NASA's incredible EPIC camera. Every two hours, EPIC takes a photo of Earth "to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth." The above video combines one year of those images.
From the NASA Goddard Space Flight Center:
The primary objective of DSCOVR, a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force, is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA.
