Airbus-built ACLS Life Support Rack is ready for launch from Tanegashima

Friedrichshafen, Germany (ESA) Sep 06, 2018
Airbus is sending a new Life Support Rack to the International Space Station (ISS). The rack also known as Advanced Closed Loop System (ACLS) has been developed by Airbus for the European Space Agency (ESA) as a technology demonstrator, which will purify air and produce oxygen for the ISS.
The Life Support Rack is stored in the pressurized part of the Japanese HTV-7, an unmanned cargo spacecraft to resupply the ISS, which is currently set to launch from Tanegashima Space Center on 11 September 2018.
It will be installed into the Destiny Module (US Laboratory) by ESA astronaut and ISS commander Alexander Gerst on 2 November 2018. Its technology is a critical step forward towards a closed loop life support system, necessary for human spaceflight beyond low Earth orbit.
Air on the ISS has a higher carbon dioxide content than on Earth, in the order of 0.4 percent. ACLS will provide additional capacity to the existing ISS life support system to remove carbon dioxide from the cabin air.
This is performed by two components: CO2 adsorption using Astrine (a solid amine resin), and use of a Sabatier reactor (using hydrogen to convert carbon dioxide into methane and water).
The third component of ESA's new Rack is its electrolyser, which produces oxygen and hydrogen from water. The oxygen produced is used to replenish the cabin air, and the hydrogen is consumed by the Sabatier reactor.
A newly formed ACLS operations team (OPS), based at Airbus in Friedrichshafen, Germany, will operate the ACLS throughout its mission. ACLS OPS is part of the ISS's ground network, and works directly with the ESA Columbus Control Center in Oberpfaffenhofen, Germany.
Following installation, the ACLS OPS team will commence a six week commissioning phase to check the new facility. Successful commissioning will be followed by operations on the ISS until the end of 2019, with the ACLS providing additional carbon dioxide removal and oxygen generation capabilities to the astronauts onboard.
Space station reports 'leak', crew not in danger
Moscow (AFP) Aug 30, 2018
The International Space Station crew on Thursday was repairing a small "leak" most likely caused by a collision with a small meteorite, the head of the Russian space agency said, adding the incident presented no danger. "Overnight and in the morning there was an abnormal situation - a pressure drop, an oxygen leak at the station," Roscosmos chief Dmitry Rogozin was quoted as saying by Russian news agencies. "A micro fracture was found, most likely it is damage from the outside. The design engin ... read more
