Astronauts Release Japanese Spaceship

Posted Nov 7, 2018 at 12:03 pm


Japan's H-II Transfer Vehicle-7 (HTV-7) is pictured moments after it was released fr om the grips of the Canadarm2 robotic arm.

Expedition 57 Commander Alexander Gerst of ESA (European Space Agency), with back-up support from NASA astronaut Serena Auñón-Chancellor, used the International Space Station's Canadarm2 robotic arm to release a Japanese cargo spacecraft at 11:51 a.m. EST. At the time of release, the space station was flying 254 miles over the northern Pacific Ocean. Earlier, ground controllers used the robotic arm to unberth the cargo craft.

After release, a new, small reentry capsule will be deployed from the unpiloted H-II Transfer Vehicle-7 (HTV-7) of the Japan Aerospace Exploration Agency (JAXA). Designed by JAXA and assembled by the station crew, the conically shaped capsule measures 2 feet in height and 2.7 feet in width. The project is a technology demonstration designed to test JAXA's ability to return small payloads from the station for expedited delivery to researchers.

HTV-7 will be a safe distance away from the space station after the last of several deorbit maneuvers. The return capsule will be ejected from a hatchway after the deorbit burn. The experimental capsule will perform a parachute-assisted splashdown off the coast of Japan, wh ere a JAXA ship will be standing by for its recovery.

The HTV-7 spacecraft is scheduled to re-enter the Earth's atmosphere and burn up harmlessly over the South Pacific Ocean Nov. 10.

ISS Daily Summary Report - 11/06/2018

Japan Aerospace Exploration Agency Low Temperature Protein Crystal Growth (JAXA LT PCG):

 Скрытый текст:

The crew retrieved JAXA LT PCG samples from the General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER)1 unit and stowed them in the H-II Transfer Vehicle (HTV) Capsule Carrier. The goal of the JAXA LT PCG experiment is to produce high quality protein crystals in a microgravity environment at a low temperature.

HTV Small Re-entry Capsule (HSRC):

 Скрытый текст:

The crew completed Parts 2 and 3 of the HTV Capsule Assembly. They also completed final closeout of the Capsule Support Plate on the HTV-7 bulkhead prior to vestibule demating. The HSRC is designed to return relatively small payloads to the ground. The HSRC is 840mm in diameter, 190kg in weight, and contains roughly 30L pressurized volume for sample return. Splashdown is scheduled to occur at 4:06 pm (CT) on Saturday, November 10.

Plasma Kristall-4 (PK-4):

 Скрытый текст:

The crew initiated the second of four PK-4 experiment runs with the start of Particle Trapping via the European Physiology Module (EPM) laptop commanding using Neon Gas. This will allow clouds of particles to be captured inside the PK-4 chamber. Between the two scripts, it is desired to perform four successful trappings. PK-4 is a scientific collaboration between the European Space Agency (ESA) and the Russian Federal Space Agency (Roscosmos), performing research in the field of "Complex Plasmas" which are low temperature gaseous mixtures composed of ionized gas, neutral gas, and micron-sized particles. The micro-particles become highly charged in the plasma and interact strongly with each other which can lead to a self-organized structure of the micro-particles - so-called plasma crystals. Experiments in the facility aim to study Transport Properties, Thermodynamics, Kinetics and Statistical Physics, and Non-linear waves and Instabilities in the plasmas.

HTV7 Departure Preparations:

 Скрытый текст:

The crew completed loading ~74 Cargo Transfer Bag Equivalent (CTBEs) of trash into the HTV vehicle. The crew configured the vestibule for demate by removing Air Revitalization System (ARS) jumper, Intermodular Ventilation (IMV) supply jumper, 1553/ENET A and B jumper, and disconnecting the Node 2 HTV channel 2 power jumper. They also installed the Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs). HTV-7 is scheduled to unberth tomorrow, November 7.

Life Support Rack (LSR) Ground Initial Activation and Checkout:

 Скрытый текст:

The ground began LSR activation and checkout, which will continue throughout the next several days. LSR is an ESA technology demonstrator for closed loop air revitalization. It captures carbon dioxide from cabin air and recovers 50% of its oxygen for use by the astronauts. LSR operates for a minimum of one year on the ISS to demonstrate the robustness of the technology for future Exploration Missions.

Роскосмос. После перезагрузки компьютера на МКС все системы работают штатно
08.11.2018

8 ноября 2018 года на российском сегменте Международной космической станции (МКС) произведена перезагрузка одного из трех центральных компьютеров, в работе которого ранее отмечался сбой.

Перезапуск системы начался в 12 час. 05 мин. мск. После успешной перезагрузки нормальная работа компьютера возобновилась. Система тестировалась на протяжении полутора витков полета станции вокруг Земли (около двух часов). По факту тестирования все системы работают штатно.

Как сообщалось ранее, на днях на одном из трех компьютеров на РС МКС произошел сбой программы. На работу МКС этот сбой никак не повлиял. Для нормального функционирования станции достаточной двух работающих компьютеров, где один резервирует второй. Менять компьютеры не планируется.

HTV 7 Release Coverage Nov. 7, 2018

Опубликовано: 7 нояб. 2018 г.

The unpiloted Japanese H-IIB Transfer Vehicle, or HTV-7, left the International Space Station Nov. 7 after a six-week delivery mission to bring scientific experiments, supplies and new batteries for the station's power system to the orbital outpost. Expedition 57 Commander Alexander Gerst of the European Space Agency, backed up by NASA Flight Engineer Serena Aunon-Chancellor used the Canadarm2 robotic arm to release the resupply vehicle, after which a series of engine firings moved the craft to a safe distance away fr om the station. The HTV-7 will be deorbited on Nov. 10 by Japanese Aerospace Exploration Agency engineers, headed for a reentry into the Earth's atmosphere, wh ere it will burn up harmlessly over the Pacific Ocean.

Mapping Carbon in 3-D

NASA Goddard

Опубликовано: 7 нояб. 2018 г.

NASA's new laser instrument, the Global Ecosystem Dynamics Investigation, or GEDI, has advanced laser technology that will reveal the makeup of remote forest ecosystems around the globe. GEDI will soar above Earth at 17,150 miles per hour onboard the International Space Station. Its measurements of the height of leaves, branches, trees, and shrubs below its path will help scientists map the structure of forests and better understand how ecosystems are storing or releasing carbon.

GEDI's lidar instrument sends laser pulses down to Earth, where they penetrate the globe's temperate and tropical forests. The laser beams ricochet off the first thing they hit, which can be a leaf atop a dense canopy, a protruding branch, or the ground from which the forest emerges. The energy returned to the GEDI tele scope on the International Space Station will provide an intricate three-dimensional map of forest canopies and carbon storage.

Led by the University of Maryland in collaboration with NASA's Goddard Space Flight Center, GEDI has the highest resolution and densest sampling of any lidar every put in orbit.
