During a five hour EVA that had lots of difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk

During a five hour EVA yesterday that had lots of minor technical difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk.

Most of the press is focusing on the PR stunt with the Olympic torch, but I think these issues are more interesting:

Working around the Service Module, Kotov and Ryazanski worked on cables at the RK21 site before attempting to fold up the panels on the hardware into its original configuration. The EVA tasks were mainly related to the preparations on the Urthecast pointing platform for installation of the HD camera in December. However, only the removal of the launch restraint from VRM EVA workstation and the disconnection of the RK-21 experiment were completed. The duo struggled with the relocation of the Yakor foot restraint – which they opted to take back to the airlock instead – while also failing to fold and lock RK-21 experiment antenna panels. While the spacewalkers managed to take a large quantity of photos for engineers on the ground to examine, the spacewalk was concluded after the failure to fold up the RK-21 panels, resulting in outstanding tasks for the next EVA.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

    I have had a problem with the word “spacewalk” ever since I first heard it,
    decades ago. Walking is using one’s legs to propel oneself along a surface
    mostly perpendicular to the direction of gravitational acceleration, blocked
    by that surface. However, every picture I’ve seen of an EVA appears to be
    drifting in (effectively) zero-gravity with one or more tethers. How can an
    EVA be described as walking? I must assume that “spacewalk” was coined
    by, and intended for, those who don’t like to think about such things. Thus,
    their minds are further muddled.

    Sounds snappy though.

  • I’d love to hear what you have to say about ‘moonwalk’ vis-a-vis the dance move.

  • What term would you prefer? “Space-diving”, akin to scuba-diving, would work just as well for me.

  • “Space-diving” implies a single direct and significant act of motion, which would not describe and EVA or spacewalk accurately. “Spacewalk” itself is a perfectly good word for EVAs. Don’s objection might have been valid once, but no longer.

    Many English words contain internal words whose meaning is contradictory or not quite accurate. It doesn’t matter because the word itself carries its own meaning independent of that internal word. “Spacewalk” has nothing to do with “walking,” and everyone knows it. It is merely a more elegant word for EVA.
