Station Officials Postpone Monday’s Spacewalk to Mid-February

International Space Station officials have postponed Monday’s spacewalk to swap latching end effectors (LEEs) on the Canadarm2 robotic arm. The decision was made after the Canadian Space Agency (CSA) and its robotics specialist team developed a diagnostics software patch confirming an anomaly noted in a primary communications string on the spare end effector installed during a prior spacewalk Jan. 23 was not hardware related, and can be corrected through the implementation of software. A confidence test verifying the software upgrade was successfully completed Saturday night.

During its initial power up after last Tuesday’s spacewalk swap, the spare latching end effector did not communicate as expected on the primary string, but did so on its backup communications string. As a result, Monday’s spacewalk by Mark Vande Hei of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA) was replanned to return the original latching end effector to the arm in place of the spare. But the software solution confirmed on Saturday will not require the spacewalkers to venture out on Monday.

The original spacewalk by Vande Hei and Kanai to bring an end effector inside the station removed from the arm during a spacewalk last October, and install the end effector removed last Tuesday on the mobile base system rail car on the station’s truss, is expected to be executed by the two crew members in mid-February.

  1. Howdy NASA,

    There is need to persuade NASA’s Impressum to Post a Normal Pictures for The Moon, without Color Filters ( as we can see in the recent post of today ‘The Moon in a Dark Orange’ Color nor posts with an IMAGINARY DRAWING either for the Moon nor for The Black Holes etc. ), in order not to distort the arguments, there is no need for any EXAGGERATION in THE EXPLAINATION, it’s not The Competition of selling NEWSPAPERS nor urging The Public Opinion to adopt an EXTREMELY POLITICS RESOLUTION for The Interest of The Financial and Political Lobby as well as for The Interest of The Arms Dealers, as it occurs in the daily behaviours in the PUBLICATIONS AND JOURNALISM since THE GREAT HUMAN CIVILIZATION BEEN FOUND.

    We are desperate to sound smart because we failed at it, while even there is no hope to get out of this NIGHTMARE.

    Good luck.

  2. I think it is a wise move to delay the spacewalk while the software patch is thoroughly vetted. No need to send astronauts into the vacuum of space without good cause! Although I suspect taking a walk outside can also be an exhilarating experience, the risk is always high and present. Bravo on the decision.
