Readers!

 

It is now July, time once again to celebrate the start of this webpage in 2010 with my annual July fund-raising campaign.

 

This year I celebrate the fifteenth anniversary since I began Behind the Black. During that time I have done more than 33,000 posts, mostly covering the global space industry and the related planetary and astronomical science that comes from it. Along the way I have also felt compelled as a free American citizen to regularly post my thoughts on the politics and culture of the time, partly because I think it is important for free Americans to do so, and partly because those politics and that culture have a direct impact on the future of our civilization and its on-going efforts to explore and eventually colonize the solar system.

 

You can’t understand one without understanding the other.

 

Please consider supporting my work here at Behind the Black. Your help allows me to do this kind of intelligent independent analysis you don’t find elsewhere. I take no advertising or sponsors, so my reporting isn’t influenced by donations by established companies or political movements. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

 

You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
 

3. A Paypal Donation or subscription:

 

4. Donate by check, payable to Robert Zimmerman and mailed to

Parker confirms it gathered science data during its record-breaking solar fly-by on December 24th

Engineers have now confirmed that during its record-breaking close fly-by of the Sun on December 24, 2024 all of its science instruments functioned as planned and were able to collect data as to that previously unexplored near-solar environment.

Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, Parker Solar Probe hurtled through the solar atmosphere at 430,000 miles per hour — faster than any human-made object has ever moved. A beacon tone, received in the mission operations center at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, late in the evening of Thursday, Dec. 26, confirmed the spacecraft had made it through the encounter safely.

The telemetry (or housekeeping data) that APL began receiving on Jan. 1 provided more detail on the spacecraft’s operating status and condition. It showed, for example, that Parker had executed the commands that had been programmed into its flight computers before the flyby, and that its science instruments were operational during the flyby itself.

A full download of this data will occur later this month, after the spacecraft further retreats from the Sun and gets in a better position to transmit it.

This ain’t the end, however. Parker has two more similar close-up fly-ups coming in March and June. Neither will break December’s records, but both will be almost as close to the Sun. After this the probe’s primary mission will be complete. At the moment there is no word if it will get extended should the probe survive intact after those fly-bys.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    I’m wondering if there is any measurable time dilation? Probably to small at 120 mile/sec. Incredible speed though.
    That’s over 3x the estimated speed of that August, 1957 manhole cover blow-out from the Pascal-B nuke test. The manhole cover was never found and was believed by some to have been blown into space unintentionally at 130,000 mph (two months before Sputnik 1).

    Some calculations
    Orbital speed 430000 mi/hr = 2e5 m/s
    C= 3e8 m/s

    So speed is about .001c

    Negligible dilation according to

    I’d like to see what the exterior of the spacecraft looks like afterwards
