NASA has requested SpaceX move off from May 1 for the launch of the company’s 17th commercial resupply mission to the International Space Station.
On April 29, the space station team identified an issue with one of the station’s Main Bus Switching Units that distributes power to two of the eight power channels on the station. There are no immediate concerns for the crew or the station. Teams are working on a plan to robotically replace the failed unit and restore full power to the station system. Additional information will be provided as it becomes available. The earliest possible launch opportunity is no earlier than Friday, May 3.
The Soyuz MS-12 launched from the Baikonur Cosmodrome in Kazakhstan to the International Space Station at 3:14 p.m. EDT (12:14 a.m. March 15 Kazakhstan time) and has safely reached orbit. At the time of launch, the station was flying about 250 miles over southern Russia, across the northeast border with Kazakhstan; more than 1,100 statute miles ahead of the Soyuz as it leaves the launch pad.
NASA astronauts Nick Hague and Christina Koch, and cosmonaut Alexey Ovchinin of Roscosmoshave begun their six-hour trip to the orbital laboratory where they will live and work for more than six months. The new crew members will dock to the Rassvet module at 9:07 p.m. Expedition 59 will begin officially at the time of docking.
About two hours later, hatches between the Soyuz and the station will open and the new residents will be greeted by NASA astronaut Anne McClain, station commander Oleg Kononenko of Roscosmos, and David Saint-Jacques of the Canadian Space Agency. The current three-person crew just welcomed the first American commercial crew vehicle as it docked to the station on March 3, amidst a busy schedule of scientific research and operations since arriving in December.
Coverage of the Soyuz docking to the International Space Station will begin on NASA TV’s media channel and the agency’s website beginning at 8:45 p.m. with the spacecraft docking expected at 9:07 p.m.
Coverage of the hatch opening between the Soyuz and the space station will begin at 10:30 p.m.
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.
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.
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.
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.
On behalf of the Expedition 58 crew, NASA Astronaut Anne McClain takes time to congratulate the NASA and SpaceX teams immediately following the Crew Dragon spacecraft’s undocking from the International Space Station at 2:32 a.m. EST Friday, March 8.
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.
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.
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 7:52 a.m. The 15-minute, 25-second burn will place the Crew Dragon on its final re-entry path into Earth’s atmosphere. The 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 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.
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.
