    The Space Show ^ | March 19, 2018 | Dr. Livingston & Guest Robert Zimmerman
    "Several recent stories regarding Trump’s space policy has prompted David Livingston to quickly schedule a Bob Zimmerman appearance on The Space Show for Monday, March 19, 7 pm (Pacific). The show will last at least ninety minutes. David especially wanted my analysis of Trump’s comments about the Falcon Heavy and SpaceX and how those comments have the big space contractors Boeing and Lockheed Martin quaking in their boots. Their fear and terror is further compounded by the present lack of a NASA administrator, which is made even worse by the announcement that the acting interim administrator is retiring at the...

    It's tough to make predictions especially about the future Science fiction has predicted many of today’s realities from cell phones to tablets. Many things that are today part of History like walking on the moon, organ transplants, and space stations were once flights of fancy. Futurists build current events on a foundation of History to provide a launching pad for visions of what is to come. One of the most widely recognized Futurists is Alvin Toffler whose seminal works include Future Shock and The Third Wave. He is also the one who told us, “Change is not merely necessary to...
  • "Mind over Matter" Stephen Hawking; An Obituary by his friend Dr. Roger Penrose

    The Guardian ^ | March 14, 2018 | Dr. Roger Penrose
    The image of Stephen Hawking – who has died aged 76 – in his motorized wheelchair, with head contorted slightly to one side and hands crossed over to work the controls, caught the public imagination, as a true symbol of the triumph of mind over matter. As with the Delphic oracle of ancient Greece, physical impairment seemed compensated by almost supernatural gifts, which allowed his mind to roam the universe freely, upon occasion enigmatically revealing some of its secrets hidden from ordinary mortal view.

This episode focuses on rationality, religion, and the challenge of thinking about probability and risk correctly in a dynamic world
  • Falling Chinese Space Station May Hit Michigan

    Experts say lower Michigan falls among one of the areas with the highest probability where free-falling 8.5-ton Chinese space station will crash into EarthScientists have an idea where and when China's free-falling 8.5-ton space station will crash into Earth. In a report by the Aerospace Corporation, Tiangong-1 is predicted to reenter the Earth’s atmosphere on or about April 3, 2018. They identified specific regions on Earth where debris from the space station could fall. A portion of lower Michigan is included on the northern "yellow band" region, which has a "higher probability" of encountering debris from the Chinese spacecraft. From...

    One of the creators of a television science fiction series has produced a highlight video, set to David Bowie's Starman, that shows some new footage of the core stage watery crash.....I have embedded the video below the fold. To me, the best part is the footage of the spectators, including the many children, wonder-struck by the launch. Some of that footage is very reminiscent of footage taken during the Apollo Saturn 5 launches in the late 1960s.....To the next generation: We are going to the Moon -- and beyond. And this time we are going to stay.

    Four tiny nanosats built by a California startup that were placed in orbit by India’s PSLV rocket in January now appear to have been launched without an FCC license....The FCC denied the license because the nanosats were so small there is a fear they could become a space junk hazard. The FCC has now vacated an approved license for launching four more Swarm satellites on a Rocket Lab Electron rocket in April because, “The FCC believes that Swarm launched and is operating its original small satellites, despite having been forbidden to do so.”

    Cool image time! In continuing my exploration of this month’s Mars Reconnaissance Orbiter (MRO) image release, I found two interesting images of small craters, one as part of that image release, the other found completely by accident...The map on the right, taken from the MRO HiRISE archive page, shows the locations of these two images...Both are located in the lava plains that surround the giant volcano Pavonis Mons, the central volcano of the three volcanoes to the east of Olympus Mons.

    Behind the Black ^ | March 9, 2018 | Robert Zimmerman
    At the beginning of a cabinet meeting yesterday Trump spent some time talking about the recent successes in commercial space. Not unusually, Trump gets some details wrong but understands the essentials, much to the terror of the big space contractors of SLS (Boeing) and Orion (Lockheed Martin). SpaceX will charge $90 million for the launch of a reused Falcon Heavy (using three reused first stages). Estimates for the cost of a single SLS launch are difficult to estimate.

    In the early 1900s, John Jacob "Jack" Astor IV was thought to be among the richest people in the world, with a net worth of nearly $87 million when he died, equivalent to $2.21 billion in 2017. In April 1912, he was traveling back home to New York after holidaying in Egypt, accompanied by his wife. Naturally, he was the richest passenger on the RMS Titanic. We’ve come a long way since the Titanic, and now the rich travel alone--and in unimaginable style. By Plane Clearly the most efficient way of transport for everyone, wealthy included, is by air. Nowadays,...

    It’s time for my monthly sunspot update. On Sunday NOAA posted its monthly update of the solar cycle, covering sunspot activity for February 2018. Below the fold is my annotated version of that graph.Sunspot activity in February continued the low activity seen in November, December, and January, with November 2017 still the most inactive month for sunspots since the middle of 2009. In fact, the low activity we are seeing now is somewhat comparable to the low activity seen during the ramp down to solar minimum in the first half of 2008.

    WGBH Forum at The Explorers Club Via YouTube ^ | June 30, 2008 | Robert Zimmerman
    The concept of what would become the Hubble Space Telescope was first envisioned after World War II, when astronomer Lyman Spitzer and a handful of scientists began a fifty year struggle to build the first space telescope capable of seeing beyond Earth's atmospheric veil. Robert Zimmerman, author of "The Universe in a Mirror: The Saga of the Hubble Space Telescope and the Visionaries Who Built It," takes us behind the scenes, explaining how some of Hubble's advocates sacrificed careers and family, and how others devoted their lives to the telescope only to have their hopes and reputations shattered when its...

    Cool image time! Yesterday the Mars Reconnaissance Orbiter team released 460 images taken by the spacecraft’s high resolution camera, HiRISE, as part of their normal and routine image release program. As I am want to do, I like to scan through these new images to see if there is anything interesting hidden there that will show up eventually in a press release...Sometimes however I find images that might never get a press release but probably deserve it....
  • New Research Finds 75% of Trans Women Can't Suppress Testosterone, Even With Hormone Therapy

    MRC TV ^ | March 1, 2018 | Brittany M. Hughes
    A full three out of four transwomen who undergo hormone therapy to “transition” into being female never reach normal female hormone levels, according to a new scientific study. I know. It's almost like it was designed to be that way or something. Here’s how it works, in a nutshell. Average adult males have testosterone levels ranging anywhere between 270-1,070 nanograms per deciliter (ng/dL). Women’s testosterone levels, on the other hand, average about 15-70 ng/dL – obviously, a much lower level. When a biological male decides he feels like a woman and chooses to medically force his physical body into accepting this delusion, he...

    ".... NASA has decided to forgo construction of a second mobile launcher for its Space Launch System (SLS). Instead, they will modify the one they have....The first mobile launcher was built and modified for an estimated $300 to $500 million. NASA obviously has decided that the politics & cost is too great, as would be the political embarrassment of admitting they spent about a half a billion for a launcher they will only use once...What this does however is push back the first manned SLS/Orion launch. At present, the first unmanned mission is likely to go in June 2020... If...

It seems he did in principle, but, judging from his final days, not in practice. A summary and excerpts follow, emphases mine."...
