Rocket Investigation Complete; Russia, Japan Announce Mission Updates













ISS - Expedition 57 Mission patch.

November 1, 2018

NASA is working closely with its International Space Station partner Roscosmos to move forward on crew launch plans. Roscosmos plans to launch the Progress 71 resupply mission on Nov. 16, and is targeting the launch of the Expedition 58 crew including NASA astronaut Anne McClain for Dec. 3, pending the outcome of the flight readiness review.

During the Soyuz spacecraft’s climb to orbit, an anomaly occurred, resulting in an abort downrange. The crew was quickly recovered in good condition. Image Credits: NASA/Roscosmos.

Roscosmos completed an investigation into the loss of a Soyuz rocket last month that led to a suspension of Russian rocket launches to the station. One of four first stage rocket engines abnormally separated and hit the second stage rocket that led to the loss of stabilization of the Soyuz on Oct. 11. A statement from Roscosmos describes the cause…

“The reason for the abnormal separation is the non-opening of the nozzle cap of the “D” block oxidizer tank because of the deformation of the stem of the separation contact sensor (bending on 6 ˚ 45 ‘), which was admitted when assembling the “package” at the Baikonur Cosmodrome. The cause of the LV accident is of operational nature and extends to the backlog of the “Soyuz” type LV “package”.

Japan also announced today the release of its H-II Transfer Vehicle-7 (HTV-7) resupply ship, also called the Kounotori, from the station’s Harmony module. Commander Alexander Gerst will command the Canadarm2 robotic arm to release Kounotori Nov. 7 at 10:50 a.m. EDT as Flight Engineer Serena Auñón-Chancellor supports him.

Named “Kounotori,” or “white stork” in Japanese, the unpiloted cargo spacecraft delivered six new lithium-ion batteries and adapter plates to replace aging nickel-hydrogen batteries used in two power channels on the space station’s port truss. Flight controllers already have robotically removed the batteries and adapter plates from HTV-7 and stored them on the space station’s truss. The batteries will be replaced through a series of robotic operations and spacewalks that will be scheduled at a later date.

Additional experiments and equipment delivered by HTV include a new sample holder for the Electrostatic Levitation Furnace (JAXA-ELF), a protein crystal growth experiment at low temperatures (JAXA LT PCG), an investigation that looks at the effect of microgravity on bone marrow (MARROW), a Life Sciences Glovebox, and additional EXPRESS Racks.

HTV-7 will re-enter the Earth’s atmosphere and burn up harmlessly over the South Pacific Ocean Nov. 10.
