<\/a>Two Expedition 69<\/a> crew members are preparing for the upcoming Northrop Grumman cargo resupply mission. Space biology and another round of eye exams are also underway today aboard the International Space Station<\/a>.<\/p>\n NASA astronauts Frank Rubio<\/a> and Woody Hoburg<\/a> spent most of their morning reviewing procedures and completing training for Northrop Grumman\u2019s<\/a> 19th<\/sup> commercial resupply mission bound for the station in August. Rubio and Hoburg will assist with the rendezvous and docking of the Cygnus spacecraft as it delivers new science investigations<\/a>, hardware and supplies for the crew. The duo also worked on the BFF-Meniscus<\/a> investigation, retrieving samples and printing with cells using the BioFabrication Facility<\/a>\u2014a 3D printer that investigates the feasibility of printing organ-like tissues in microgravity.<\/p>\n Later in the evening, Rubio assisted and guided another set of eye exams on NASA astronaut Stephen Bowen<\/a>. Ahead of exams, Bowen collected saliva samples for ongoing research and replaced filters in the station\u2019s Waste and Hygiene Compartment.<\/p>\n United Arab Emirates (UAE) Flight Engineer Sultan Alneyadi<\/a> ran Genes in Space-10<\/a> operations which measure and analyze DNA length using fluorescent samples. The Genes in Space<\/a> program consists of ongoing investigations that allow middle and high school students to design DNA experiments that address a challenge in space exploration.<\/p>\n Commander Sergey Prokopyev<\/a> of Roscosmos wore a sensor-packed cap for the Pilot-T experiment, an investigation that provides crew members the opportunity to practice piloting techniques and explore how spacefarers may react and control spacecraft on future planetary missions. Flight Engineer Andrey Fedyaev<\/a> assessed device operations in the Nauka<\/a> module, and was later given an eye exam using imaging hardware that Flight Engineer Dmitri Petelin<\/a> guided.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0https:\/\/roundupreads.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
