Spacewalkers Nick Hague and Anne McClain
NASA astronauts Nick Hague (top) and Anne McClain work to swap batteries in the Port-4 truss structure during today’s spacewalk.

Expedition 59 Flight Engineers Nick Hague and Anne McClain of NASA concluded their spacewalk at 1:40 p.m. EDT. During the six-hour, 39-minute spacewalk, the two NASA astronauts successfully replaced nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station’s solar arrays.

Astronauts were also able to accomplish several get-ahead tasks including removing debris from outside of the station, securing a tieback for restraints on the Solar Array Blanket Box, and photographing a bag of tools for contingency repairs and the airlock thermal cover that is opened and closed for spacewalks.

These new batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries. Next week, McClain and flight engineer Christina Koch are scheduled to venture outside on the March 29 spacewalk to work on a second set of battery replacements on a different power channel in the same area of the station. This would be the first-ever spacewalk with all-female spacewalkers.

Hague and David Saint-Jacques of the Canadian Space Agency are scheduled to conduct a third spacewalk April 8 to lay out jumper cables between the Unity module and the S0 truss, at the midpoint of the station’s backbone. This work will establish a redundant path of power to the Canadian-built robotic arm, known as Canadarm2. They also will install cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.

Space station crew members have conducted 214 spacewalks in support of assembly and maintenance of the orbiting laboratory. This was the first spacewalk for both McClain and Hague. Spacewalkers have now spent a total of 55 days, 21 hours and 39 minutes working outside the station.

NASA astronaut Nick Hague verifies his U.S. spacesuit is sized correctly and fits properly ahead of a set of upcoming spacewalks.

Two astronauts switched their spacesuits to battery power this morning at 8:01 a.m., EDT aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours.

Expedition 59 Flight Engineers Nick Hague and Anne McClain of NASA will install adapter plates and hook up electrical connections for three of six new lithium-ion batteries installed on the station’s starboard truss. McClain is designated extravehicular crewmember 1 (EV 1), wearing the suit with red stripes, and with the helmet camera labeled #20. Hague is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes, and with helmet camera #17.

The batteries store power generated by the station’s solar arrays to provide power to the station when the station is not in the sunlight, as it orbits the Earth during orbital night. Next week, McClain and flight engineer Christina Koch are scheduled to venture outside on the March 29 spacewalk to work on a second set of battery replacements on a different power channel in the same area of the station. Additional batteries will be replaced as part of this power upgrade over the next couple of years as new batteries are delivered to station.

Watch the spacewalk on NASA TV and on the agency’s website.

The last full day of Expedition 58—before the launch, docking and consolidation of crews to become Expedition 59—was mostly spent on housekeeping items for the continued, successful operation of the International Space Station. 

NASA astronaut Anne McClain floated through the Tranquility and Zvezda service modules, deploying acoustic monitors. She paused in the U.S. lab at an EXPRESS rack to install communications gear and perform additional maintenance. David Saint-Jacques of the Canadian Space Agency also worked with EXPRESS today, moving Space Automated Bioproduct Labs from rack-1 to rack-2. This miniature laboratory within the larger orbiting laboratory supports life science research, hosting microorganisms (bacteria, yeast, algae, fungi, viruses, etc.), small organisms, animal cells, tissue cultures and small plants for evaluation in space.  

Expedition Commander Oleg Kononenko of Roscosmos replaced fuel bottles on the Combustion Integrated Rack, which allows the crew members to conduct fluids and combustion studies in microgravity. 

Today in Baikonur, Kazakhstan, NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmos, were certified for flight by the Russian state commission and held their final news conference.  

Tomorrow, the soon-to-be station residents will hitch a ride aboard a Soyuz MS-12 for blastoff at 3:14 p.m. EDT on, coincidentally, 3/14. After a relatively speedy six-hour flight, the Soyuz is expected to dock to station’s Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking. 

The events will unfold live on NASA TV, with launch coverage beginning at 2 p.m. and docking coverage at 8:15 p.m., respectively. After a brief break, tune in at 10:30 p.m. for the hatch opening and welcome, which will return the orbiting laboratory’s population to six—including three NASA astronauts. And, just in time for Women’s History Month, this launch marks the fourth Expedition crew with two female astronauts.

As the Soyuz MS-12 that will carry the Expedition 59 crew to the International Space Station Thursday was erected on the launch pad at the Baikonur Cosmodrome in Kazakhstan, Expedition 58 resumed research and routine maintenance after their off-duty day Monday. 

NASA astronaut Anne McClain conducted botany work with the VEG-03 experiment, which builds on what scientists have initially learned about harvesting vegetation in space with VEG-01. This time around, testing will demonstrate plant growth with a new batch of crops, including red romaine lettuce, extra dwarf Pak Choi, red Russian kale and wasabi mustard. McClain also spent time on life-support system upkeep in the Kibo lab module and maintenance in the U.S. lab on an EXPRESS rack—hardware integral to providing structural interfaces and support for science experiments with power, data, cooling, water and other items needed for successful operations. 

In the Quest airlock, Canadian Space Agency astronaut David Saint-Jacques completed additional prep work for upcoming spacewalks slated for March 22, 29 and April 8 by scrubbing cooling loops and performing leak checks on the spacesuits. After resupplying the Human Research Facility-2 rack, Saint Jacques added input to a questionnaire for Behavioral Core Measures, an investigation that seeks to create a standardized toolkit to rapidly and reliably assess the risk of adverse cognitive or behavioral conditions and psychiatric disorders that could occur with longer space missions. 

Meanwhile, Commander Oleg Kononenko from Roscosmos ticked off additional maintenance tasks by cleaning panels in the Zvezda service module and performing fluid transfers to the Progress 71 resupply ship.

This Monday, the Expedition 58 crew is taking a well-deserved break after a busy week prior wrapping up SpaceX’s inaugural flight of Crew Dragon to the International Space Station during Demonstration Mission-1, an uncrewed flight test. The vehicle departed station for a splashdown off the Florida Space Coast at 8:45 a.m. EST Friday, bringing NASA even closer to sending astronauts into space from American soil. 

The Expedition 59 crew, which will soon get their turn in orbit, is taking time to relax and review their launch day flight plan at the Baikonur Cosmodrome in Kazakhstan. On March 14, Commander Alexey Ovchinin and Flight Engineers Nick Hague and Christina Koch are set to blastoff at 3:14 p.m. EDT and dock less than six hours later to the Rassvet module at the orbiting laboratory. Research investigations will get a boost in productivity with their arrival, which will bring the full crew complement to six. All launch and docking events will be carried live on NASA TV. 

Tomorrow, the Soyuz MS-12 that will carry the new crew crawls to the launch pad at Baikonur as Expedition 58 resumes science studies.

SpaceX’s Crew Dragon splashes down in the Atlantic Ocean after successful Demo-1 flight on March 8, 2019.

SpaceX’s Crew Dragon returned to Earth with a splash in the Atlantic Ocean off Florida’s eastern shore at 8:45 a.m. EST, completing an end-to-end flight test to demonstrate most of the capabilities of its crew transportation system to the International Space Station as part of NASA’s Commercial Crew Program.

The mission, known as Demo-1, is a critical step for NASA and SpaceX to demonstrate the ability to safely fly missions with NASA astronauts to the orbital laboratory.

The Crew Dragon launched March 2 from NASA’s Kennedy Space Center in Florida. It was the first commercially-built and operated American crew spacecraft and rocket to launch from American soil on a mission to the space station and autonomously dock to the station. To complete the docking, both the station and Crew Dragon’s adapters used the new international docking standard.

Crew Dragon is returning to Earth some critical research samples from science investigations conducted to enable human exploration farther into space and develop and demonstrate in the U.S. ISS National Laboratory new technologies, treatments, and products for improving life on Earth.

Also traveling aboard the spacecraft is an anthropomorphic test device named Ripley outfitted with sensors to provide data about potential effects on humans traveling in Crew Dragon.

SpaceX’s recovery ship, Go Searcher, is equipped with a crane to lift Crew Dragon out of the water and onto the main deck of the ship within an hour after splashdown.

NASA and SpaceX still have work to do to review the systems and flight data to validate the spacecraft’s performance and prepare it to fly astronauts. Already planned upgrades, additional qualification testing, and an in-flight abort test will occur before NASA astronauts Bob Behnken and Doug Hurley will climb aboard for Demo-2, the crewed flight test to the International Space Station that is necessary to certify Crew Dragon for routine operational missions.

Crew Dragon’s splashdown in the Atlantic was almost 50 years after the return of Apollo 9 on March 13, 1969, the last human spacecraft to return to the waters off the East Coast.

Watch NASA TV to See Crew Dragon’s Return to Earth

NASA is providing live coverage of the return to Earth of SpaceX’s Crew Dragon after five days docked to the International Space Station.

Known as Demo-1, SpaceX’s inaugural mission with NASA’s Commercial Crew Program is an important uncrewed end-to-end flight test of the new system’s capabilities.

The spacecraft departed the space station at 2:32 a.m. EST and is on track for a splashdown in the Atlantic Ocean about 200 nautical miles off the eastern shore of Florida.

At approximately 7:48 a.m., Crew Dragon will separate from its trunk containing its solar array and radiator. Four minutes later, the spacecraft’s thrusters will initiate the deorbit burn at 7:52 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The nosecone will be closed before the spacecraft enters the atmosphere.

At about 8:41 a.m., drogue parachutes will deploy, and the four main chutes will begin to open less than a minute later to slow the Crew Dragon during its final descent prior to its water landing at about 8:45 a.m.

SpaceX’s two recovery ships are positioned nearby to recover Crew Dragon and return it to Cape Canaveral Air Force Station, Florida, to conclude its mission.

More details about the mission and NASA’s commercial crew program can be found in the press kit online and by following the commercial crew blog, @commercial_crew and commercial crew on Facebook.

At 2:32 a.m. EST, Crew Dragon undocked from the International Space Station to begin the final phase of its uncrewed Demo-1 flight test. The spacecraft is slowly maneuvering away from the orbital laboratory into an orbital track that will return it and its cargo safely to Earth.

NASA will continue to provide live coverage until Crew Dragon is out of the immediate area of the station and will resume at 7:30 a.m. for the reentry, splashdown, and recovery.

In about five hours, the Crew Dragon will separate from its trunk whose exterior contains a solar array that provided power to Dragon and a radiator to reject heat.

Following separation, Crew Dragon’s thrusters will initiate the spacecraft’s deorbit burn at about 7:53 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The spacecraft is expected to splashdown in the Atlantic Ocean at about 8:45 a.m., its speed slowed by an enhanced parachute system in which drogue parachutes will deploy about four minutes before landing to unfurl four main chutes less than a minute later.

After Crew Dragon lands in the Atlantic Ocean, SpaceX’s recovery ship will recover it and return it to Port Canaveral, Florida to conclude its mission.

SpaceX’s inaugural mission with NASA’s Commercial Crew Program is an important end-to-end to test of the new system’s capabilities.

The uncrewed SpaceX Crew Dragon spacecraft is the first Commercial Crew vehicle to visit the International Space Station. Here it is pictured with its nose cone open revealing its docking mechanism while approaching the station’s Harmony module on March 3, 2019.

The SpaceX Crew Dragon’s hatch is closed and the stage is set for the Commercial Crew Program’s first undocking and return to Earth Friday. As NASA and SpaceX get ready for Friday’s splashdown, the Expedition 58 crew continued exploring a variety of space physics phenomena aboard the International Space Station.

The uncrewed SpaceX DM-1 mission has one final milestone and that is the safe return to Earth with a splashdown in the Atlantic Ocean around 8:45 a.m. EST Friday. The Crew Dragon will undock Friday at 2:31 a.m. from the Harmony module’s international docking adapter. NASA TV will broadcast the departure and return activities live.

The first commercial crew vehicle from SpaceX will be bringing back over 330 pounds of science gear, crew supplies and station hardware. It delivered almost 450 pounds of materials to resupply the station crew on March 3.

Science took precedence as usual aboard the orbital lab today as SpaceX prepares to welcome its Crew Dragon back on Earth.

NASA astronaut Anne McClain spent Thursday morning setting up hardware to explore ways to improve the production of higher-quality semiconductor crystals. Afterward, she relocated the Alpha Magnetic Spectrometer laptop computer that researches cosmic rays and antimatter from the Columbus lab module to the Destiny lab module.

Commander Oleg Kononenko worked throughout the day on a Russian-European experiment researching plasma physics. The Plasma Krystal-4 study observes plasma crystal formation that could inform future research and spacecraft designs.
