Ax-3 Mission Countdown: ISS Crew Readies for Historic Private Astronaut Arrival

Four private astronauts are readying for launch to the International Space StationThe International Space Station (ISS) is a large spacecraft in orbit around the Earth that serves as a research laboratory and spaceport for international collaboration in space exploration. It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>International Space Station this week while the Expedition 70 crew ramps up microgravity research and maintenance tasks after yesterday’s off-duty day.

The third private astronaut mission to the station, Axiom Mission 3 (Ax-3), is scheduled to liftoff from Launch Complex 39A at NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>NASA’s Kennedy Space Center in Florida at 5:11 p.m. ESTEST is an abbreviation for Eastern Standard Time, the time zone for the eastern coast of the United States and Canada when observing standard time (autumn/winter).

Ahead of Ax-3 arrival, NASA Flight Engineer Loral O’Hara spent most of the day prepping the station for new visitors. O’Hara inspected the airflow in crew quarters, prepped sleep accommodations for crew occupancy, and cleaned the liners and vents where the four private astronauts will sleep while aboard the orbital outpost.

ESA (European Space Agency) Commander Andreas Mogensen also prepped for Ax-3, completing training for Dragon rendezvous and docking. Afterward, he set up ECHO, which is equipped with motorized probs, for ground teams to perform remote maintenance activities.

While O’Hara and Mogensen prepped for Ax-3 crew arrival, other crew members took to space botany and biology tasks. NASA Flight Engineer Jasmin Moghbeli spent the day working with Plant Habitat-06, thinning wild-type tomato seedlings. Afterward, she set up and installed the Plant Water Management 5 hardware to the Maintenance Work Area.

JAXAFormed in 2003, the Japan Aerospace Exploration Agency (JAXA) was born through the merger of three institutions, namely the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL) and the National Space Development Agency of Japan (NASDA). JAXA performs various activities related to aerospace, from basic research in the aerospace field to development and utilization and is responsible for research, technology development, and launch of satellites into orbit, and is involved in advanced missions such as asteroid exploration and possible human exploration of the Moon.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>JAXA (Japan Aerospace Exploration Agency) Flight Engineer Satoshi Furukawa removed culture units from the microscope used for the Space Organogenesis investigation, which demonstrates growth of organ buds from 3D-printed human stem cells.

The RoscosmosRoscosmos, also known as the Roscosmos State Corporation for Space Activities, is the Russian government agency responsible for space activities, including the development and operation of spacecraft, launch vehicles, and space stations. It was formed in 2015 through the merger of the Federal Space Agency (Roscosmos) and the United Rocket and Space Corporation. Roscosmos is responsible for Russia's space program and works closely with other international space agencies on joint projects, such as the International Space Station. The agency is also involved in a wide range of space-related activities, including scientific research, earth observation, telecommunications, and manned spaceflight.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]” tabindex=”0″ role=”link”>Roscosmos trio—Flight Engineers Oleg Kononenko, Nikolai Chub, and Konstantin Borisov—performed an array of maintenance activities on Tuesday.
