For the first time, they will also relocate some research hardware already on the station into a rack inside the Cygnus cargo module, using the facility as a temporary research base.<\/p>\n<p>Among the scientific supplies delivered to the station Tuesday were gas bottles to support an advanced combustion microgravity experiment, a habitat for research rodents launching on a future mission, and items for a 3D printer aboard the orbiting laboratory, according to Camille Alleyne, associate space station program scientist at NASA\u2019s Johnson Space Center in Houston.<\/p>\n<p>Two CubeSats will be transferred inside the space station to join three others for release into orbit through the Japanese lab module\u2019s airlock.<\/p>\n<p>One of the CubeSats is named the E. Coli Antimicrobial Satellite, or EcAMSat, is about the size of a small briefcase. Developed by engineers at NASA\u2019s Ames Research Center and scientists at Stanford University, EcAMSat will study the antibiotic resistance in space of E. coli, a bacterial pathogen responsible for urinary tract infection in humans and animals.<\/p>\n<p>EcAMSat\u2019s mission is expected to last more than a year, and two types of E. coli cells \u2014 a wild and a mutant strain \u2014 contained in 48 microfluidic wells inside the CubeSat\u2019s miniature laboratory will be activated, grown and tested once the 23-pound (10-kilogram) satellite is ejected from the station\u2019s Japanese robotic arm, according to Stevan Spremo, EcAMSat\u2019s project manager.<\/p>\n<p>\u201cWith this, we believe that we\u2019ll learn more about antibiotic resistance in the microgravity environment, where E. coli are known to grow more virulently in space,\u201d Spremo said.<\/p>\n<p>The results could help protect astronauts on future space missions and develop countermeasures that may be useful for humans on Earth, he said.<\/p>\n<p>The other small spacecraft carried on the OA-8 mission and destined for deployment through the Kibo airlock is TechEdSat 6, another experimental CubeSat from the Ames Research Center in partnership with San Jose State University and the University of Idaho.<\/p>\n<figure id=\"attachment_28562\" aria-describedby=\"caption-attachment-28562\" style=\"width: 675px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-28562\" src=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/11\/22-2.jpg\" alt=\"\" width=\"675\" height=\"321\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/11\/22-2.jpg 900w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/11\/22-2-300x143.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/11\/22-2-768x365.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/11\/22-2-678x322.jpg 678w\" sizes=\"(max-width: 675px) 100vw, 675px\"><figcaption id=\"caption-attachment-28562\" class=\"wp-caption-text\">Artist\u2019s concept of the TechEdSat 6 spacecraft.

The technology could eventually allow some space station research samples to return to Earth sooner, and at less expense.<\/p>\n<p>Station astronauts will repack the Cygnus spacecraft\u2019s Italian-built logistics module with trash before closing hatches and detaching the supply ship from the Unity module with the robotic arm Dec. 3.<\/p>\n<p>Mission control will maneuver the Cygnus a few feet from another berthing port on the station\u2019s Harmony module, where crew capsules from Boeing and SpaceX are expected to dock once they are ready to begin flying astronauts into orbit.<\/p>\n<p>Engineers will use the Cygnus spacecraft to simulate the presence of a commercial crew craft at Harmony\u2019s space-facing port and check to ensure it does not block GPS navigation signals from reaching the space station.<\/p>\n<p>Once those tests are finished, the robotic arm will release Cygnus on Dec. 4, and Orbital ATK\u2019s ground team will send commands to raise the ship\u2019s orbit to an altitude of around 300 miles (500 kilometers).<\/p>\n<p>In that orbit, Cygnus will deploy 14 more CubeSats \u2014 ranging in size from a Rubik\u2019s Cube to a loaf of bread \u2014 from an external device provided by NanoRacks, a Houston-based company that offers small satellite deployments on space station cargo flights.<\/p>\n<p>\u201cOA-8 is yet another unique mission for NanoRacks,\u201d said Henry Martin, NanoRacks\u2019 senior mission manager. \u201cWe\u2019re thrilled to have a full external Cygnus deployer, displaying its maximum capability. This mission also brings new customers from outside the industry into space while continuing partnerships with existing customers like Spire for their ongoing satellite constellation. Notably, this mission will also deploy our first-ever propulsive satellite from the Cygnus spacecraft.\u201d<\/p>\n<figure id=\"attachment_25501\" aria-describedby=\"caption-attachment-25501\" style=\"width: 675px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-25501\" src=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/06\/Lemur-2-Testing.jpg\" alt=\"\" width=\"675\" height=\"450\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/06\/Lemur-2-Testing.jpg 675w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/06\/Lemur-2-Testing-300x200.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2017\/06\/Lemur-2-Testing-30x20.jpg 30w\" sizes=\"auto, (max-width: 675px) 100vw, 675px\"><figcaption id=\"caption-attachment-25501\" class=\"wp-caption-text\">One of Spire\u2019s Lemur satellites.

Wilson in California,\u201d said Richard Welle, Aerospace senior scientist and one of the principal investigators for OCSD. \u201cThis is the first CubeSat laser communications system that will demonstrate an optical downlink. This compact laser package with its potential for much higher rates proves a promising future for CubeSat-scale laser communications.\u201d<\/p>\n<p>The ISARA CubeSat developed by the Jet Propulsion Laboratory will study the performance of an integrated solar array and radio antenna and a compact suite of three visible and infrared cameras that could be employed on future weather satellites.<\/p>\n<p>The Naval Postgraduate School\u2019s PropCube 2 CubeSat is also slated for deployment from Cygnus in December to measure disturbances in the ionosphere, an upper layer of Earth\u2019s atmosphere.<\/p>\n<p>The Cost-effective High E-Frequency Satellite, or CHEFSat, from the Naval Research Laboratory will help engineers gauge the performance of a consumer-grade radio frequency device in space.<\/p>\n<p>The first satellite for Asgardia, an organization that aims to become the first nation state in space, was also launched Sunday. The group was created by Igor Ashurbeyli, a Russian scientist, and the Asgardia 1 satellite hosts a 500-gigabyte solid state drive containing files and data uploaded by the organization\u2019s supporters, or citizens.<\/p>\n<p>The Cygnus spacecraft will fall out of orbit in December after wrapping up the CubeSat deployments and burn up in the atmosphere over the South Pacific Ocean, discarding the space station\u2019s trash and other unneeded items tagged for disposal by NASA.<\/p>\n<p>Orbital ATK is one of two NASA contractors with operational resupply vehicles for the space station.<\/p>\n<p>The space agency awarded contracts to Orbital ATK and SpaceX in 2008 to ferry cargo to the research lab after the retirement of the space shuttle. Orbital originally received a $1.9 billion contract for eight missions, a deal that was later extended to 11 flights.<\/p>\n<p>The current mission, known as OA-8, is the eighth flight in Orbital ATK\u2019s cargo resupply contract. NASA awarded Orbital ATK, SpaceX and newcomer Sierra Nevada Corp. a new round resupply contracts in 2016, guaranteeing each company a minimum of six more cargo missions from 2019 through 2024.<\/p>\n<p>That bumps Orbital ATK\u2019s backlog to at least nine more Cygnus resupply flights in the next seven years, most of which are expected to launch on the company\u2019s own Antares booster from Virginia. Orbital ATK also has the option to launch Cygnus missions using United Launch Alliance Atlas 5 rockets.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Cygnus supply ship on final approach to the International Space Station on Tuesday.
