NASA astronauts Joe Acaba, Scott Tingle and Mark Vande Hei have wrapped up cargo operations inside the SpaceX Dragon disconnecting power cables and depressurizing the vehicle. Robotics controllers will detach Dragon resupply ship from the International Space Station’s Harmony module tonight. Dragon will then be remotely released from the grip of the Canadarm2 into Earth orbit at 5 a.m. EST Saturday for a Pacific Ocean splashdown at 10:36 a.m.

Acaba and Tingle will monitor Dragon’s departure Saturday morning from inside the cupola as controllers on Earth release a cargo craft remotely from the space station for the first time. NASA TV will broadcast live the resupply ship’s departure starting Saturday at 4:30 a.m. Splashdown will not be televised.

Japanese astronaut Norishige Kanai worked a variety of life science experiments today exploring what happens to humans living in space. He started the morning drawing his blood samples and storing them in a science freezer for later analysis. He also stowed frozen science samples inside Dragon for return to Earth. At the end of the day, Kanai removed petri plates from a specialized microscope containing plant samples being observed for molecular and genetic changes caused by microgravity.

Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov took body mass measurements this morning on a device that applies a known force on the subject with the resulting acceleration being used to calculate mass. The duo also partnered up for a pair of biomedical experiments including the Biocard cardiovascular study and the DAN blood pressure study.

The Expedition 54 crew aboard the International Space Station is training for this weekend’s departure of the SpaceX Dragon commercial cargo craft. The crew is also exploring regenerative life support systems and how microgravity affects breathing.

NASA astronauts Joe Acaba and Scott Tingle began their day training and reviewing for Saturday’s remotely controlled release of the Dragon resupply ship at 5 a.m. The duo took onboard computer training and discussed this weekend’s activities with engineers at Mission Control.

This is the first time robotics controllers will command the release of Dragon from the ground while Acaba and Tingle monitor from the cupola as backups. NASA TV will broadcast live the resupply ship’s departure starting Saturday at 4:30 a.m. Splashdown off the coast of California is expected at 10:36 a.m. and will not be televised.

Experimental work also took place today on the orbital laboratory to help NASA learn how to support astronauts on longer missions farther out into space.

Acaba checked bacteria cultures that could be used for carbon dioxide removal and oxygen production supporting future regenerative life support systems. Japanese astronaut Norishige Kanai joined NASA astronaut Mark Vande Hei and measured their breathing rates today, specifically Nitric Oxide turnover in the lungs. Doctors want to minimize the risk of airway inflammation to keep astronauts healthier farther from Earth.

Robotics controllers are getting ready to uninstall the SpaceX Dragon cargo craft from the International Space Station on Friday before releasing it for a splashdown in the Pacific Ocean Saturday. The Expedition 54 crew today is also continuing to study how living in space affects biology and introducing space travel concepts to students on Earth.

The crew is finishing packing up the Dragon this week and will close the spaceship’s hatch Friday and wrap up cargo operations. Houston mission controllers will remotely perform Dragon’s release operation for the first time early Saturday. Flight Engineers Joe Acaba and Scott Tingle will be inside the cupola monitoring Dragon’s departure.

Dragon will be depart the station Saturday at 5 a.m. EST loaded with science experiments and station cargo and parachute to a splashdown off the coast of California at 10:36 a.m. NASA TV will broadcast live the resupply ship’s departure starting Saturday at 4:30 a.m.

Life science continues at full pace aboard the aboard orbital laboratory today. Japanese astronaut Norishige Kanai checked on rodents being treated with a compound that fights muscle loss in microgravity. Tingle took a look at plant samples to observe their genetic and molecular responses to growing in space.

Commander Alexander Misurkin along with Acaba set up a pair of tiny internal satellites, also known as SPHERES, for a dry run today ahead of a competition. Students on Earth are competing to design the best algorithms that will operate the SPHERES to simulate future space operations such as dockings and flying formations.

Robot Arm Finishes Swapping Experiments Outside Dragon

Robotics controllers have completed the science cargo transfers from the rear of the SpaceX Dragon cargo ship, also known as its trunk. Dragon is due to depart the International Space Station Jan. 13 and return to Earth.

Over the holidays, the ground robotics teams remotely operated the Canadarm2 to remove a pair of new external experiments from Dragon and install them on the station. The teams also finished installing an older experiment back inside the cargo craft’s trunk in time for its departure.

Dragon delivered the Total and Spectral Solar Irradiance Sensor (TSIS-1) and the Space Debris Sensor (SDS) when it arrived on Dec. 17, 2017. TSIS-1 was attached to an External Logistics Carrier on the port solar alpha rotary joint. It will study the sun’s natural influence on the Earth’s ozone layer, atmospheric circulation, clouds, and ecosystems. The SDS was installed outside the Columbus lab module where it will directly measure the orbital debris environment around the space station for two to three years.

The successful RapidScat experiment was installed back in Dragon’s trunk after being delivered in September 23, 2014, on the SpaceX CRS-4 mission. RapidScat observed wind patterns on the ocean’s surface providing agencies better data for weather forecasting before ending its mission in August of 2016.

RapidScat will be destroyed inside Dragon’s trunk when it separates from the Dragon resupply ship to burn up over the Pacific Ocean. Dragon itself will safely parachute to a splashdown in the Pacific Ocean off the southern coast of California.

The Expedition 54 crew is starting the New Year studying how humans adapt to living in space for months and years at a time. NASA and its international partners are also learning how to support crews on longer missions with less help from the ground.

The astronauts and cosmonauts on the International Space Station orbit Earth 16 times a day affecting their circadian rhythms, or biological clocks. Japanese astronaut Norishige Kanai is helping doctors understand how being away from the normal 24-hour sunrise-sunset cycle impacts the human body. He strapped on sensors today that will measure his body composition and temperature for 36 hours.

NASA astronaut Mark Vande Hei is helping engineers design closed-loop systems keeping crews self-sufficient on longer missions beyond low-Earth orbit. He swapped experimental containers in the Biolab Incubator containing bacteria cultures that could be used for carbon dioxide removal and oxygen production.

Crews also need to be prepared for bone injuries or dental work that may be necessary during a space mission. The Synthetic Bone experiment, that Flight Engineer Joe Acaba worked on today with Kanai, is testing how a synthetic material integrates with bone cells to address bone fractures and bone loss in space and on Earth.

International Crew Researching Life Science Ahead of New Year

After a Russian cargo ship departed the International Space Station Thursday, the Expedition 54 crew is wrapping up the final work week of 2017 orbiting Earth and conducting science. The six astronauts and cosmonauts will go into the last weekend of 2017 with light duty and family conferences before taking New Year’s Day off.

The Progress 67 (67P) resupply ship finished its stay six-and-a-half month at the station’s Zvezda service Thursday at 8:03 a.m. EDT. Cosmonauts Alexander Misurkin and Anton Shkaplerov packed the 67P full of trash the closed its hatches before it automatically undocked. It will re-enter Earth’s atmosphere and safely burn up over the south Pacific Ocean.

Japanese astronaut Norishige Kanai took his turn on the exercise bike today for a study researching physical exertion in space. Doctors measure the astronauts breathing and other parameters during exercise to ensure they have the strength to perform strenuous activities such as spacewalks and even emergency procedures.

Flight Engineer Scott Tingle of NASA was harvesting plants for the Advanced Plants Experiment-05 (APEX) and stowing the botany samples in a science freezer for further analysis. Scientists are exploring how plants respond to microgravity and observing molecular and genetic changes.

The life science studies help mission doctors keep astronauts healthier and stronger while living in outer space. Also, NASA is planning longer human missions beyond low-Earth orbit and learning how to keep crews self-sustainable.

Finally, three U.S. astronauts, two Russian cosmonauts and a Japanese astronaut on the orbital laboratory will experience New Year’s Eve 16 times as they orbit Earth once every 90 minutes. That is 16 sunrise and sunsets 250 miles above Earth. The crew will take the day off, share a meal and reflect on the past year and plan for the year ahead.
