Ode to JOI (Jupiter Orbit Insertion)

What will NASA’s Juno spacecraft find when it reaches Jupiter next Monday? Very little, if Juno does not survive Jupiter Orbit Insertion, a complex series of operations in an unknown environment just above Jupiter’s cloud tops. If successful, as explained in the featured video, Juno will swoop around Jupiter, passing closer than any previous spacecraft. The goal is to decelerate, enter into a highly elliptical orbit, and begin two years of science operations. Juno’s science mission objectivesinclude mapping Jupiter’s deep structure, determining how much water is in Jupiter’s atmosphere, and exploring Jupiter’s powerful magnetic field and how it creates auroras around Jupiter’s poles. These lessons hold promise to help humanity better understand the history of our Solar System and the dynamics of our Earth. Juno is powered predominantly by three large solar panels, each measuring a side of small truck. Launched in 2011, Juno’s planned mission will take it around the Jovian giant 37 times, after which, to avoid contaminating Europa with microbes, it will be directed to dive into Jupiter‘s thick atmosphere, where it will break apart and melt.

How 100 Syrians, 200 Russians and 11 Dogs Out-Witted ISIS and Saved Palmyra

There was nothing used by Daesh* (ISIS) that the Syrian and Russian ordnance disposal specialists were unfamiliar with. But the breadth and detail of the wiring and explosives Daesh placed hidden among the ruins were found to be very sophisticated.

The Daesh plan which was also apparently referenced in a document later recovered from the Museum was dubbed “Erase.” (“Mahaqa” in Arabic). Daesh planned to “Erase” the whole area of our ancient ruins and Daesh hoped to kill at least 1000 Syrian troops who they assumed would be among the ruins when they were detonated.

The dangerous work of clearing the unexploded ordnance was performed by many to date unsung heroes; among them are 100 Syrian and 200 Russian unexploded ordnance specialists and 11 Russian explosive detecting dogs.

Some robots were all deployed as part of the massive around clock bomb clearing operation.

At the end of the intense 30 days of heroic work, which claimed the lives of two soldiers and wounded others, no fewer than 4000 booby-trap bombs were defused and removed from among our cultural heritage ruins at ancient Palmyra.

Experts at Palmyra have recently formed three units specializing in engineering, archeological evaluations and restoration of damage artifacts. As noted above, it is widely believed here that 95% of damage caused by Daesh can and will be restored.

Even a higher percentage can be restored some archeologists working here estimate. And 95% of all the ruins were untouched.

Every Sperm Whale Alive Today May Have Descended From the Same Female

At some point in the last 80,000 years, became the “mother” of all sperm whales who followed. Though it would make sense to have a single mother in a single area—an ancestor who, say, really loved the Pacific Ocean—this mom’s genes have been found in sperm whales all over the world.How this happened remains unknown and is even stranger given sperm whales’ social structures. Sperm whales are matrilineal, meaning most females stick together and males come and go, which would limit how far a female’s genes could travel.

Christo and Jeanne-Claude: The Floating Piers, Lake Iseo, Italy

Floating_Piers_on_Lake_Iseo_node_full_image_2

Satellite view of the installation of “The Floating Piers”

For sixteen days – June 18 through July 3, 2016 – Italy’s Lake Iseo is being reimagined. 100,000 square meters of shimmering yellow fabric, carried by a modular floating dock system of 220,000 high-density polyethylene cubes, undulate with the movement of the waves as The Floating Piers rise just above the surface.

I found these images of the installation fascinating.

V&A · Revolution? Records and Rebels 1966-1970

I am to be part of this exhibition at the Victoria & Albert Museum because of my work as a Haight Ashbury historian. I have just booked my passage for a two-week stay in London.

Yes, I know this is not from the Haight.

How have the finished and unfinished revolutions of the late 1960s changed the way we live today and think about the future?

The Tenderloin | Up From The Deep

A WORK IN PROGRESS The architectural data in this section was first researched over twenty-five years ago by the late Anne Bloomfield, and more recently—in depth and with meticulous attention to detail—by Michael Corbett, with whom I worked in 2007-8 on a survey of the Tenderloin for the National Register of Historic Places district nomination. Historical details have been drawn from my own research and personal experience, as well as the painstaking research of friend and fellow historian Peter Field, who each spring and fall gives free historical walking tours of the Tenderloin, which I highly recommend to all.

A friend just turned me on to this amazing history of the Tenderloin. It’s long and very detailed with LOTS of historical photos and images. I’ve only read about half so far but wanted to share it.
