NASA Astronauts Safely Splash Down after First Commercial Crew Flight to Space Station


SpaceX's Crew Dragon, carrying NASA astronauts Robert Behnken and Douglas Hurley, splashes down in the Gulf of Mexico off the coast of Pensacola, Florida at 2:48 p.m. EDT Aug. 2, 2020, where the spacecraft is recovered by SpaceX and brought aboard the recovery ship 'Go Navigator.'

Two NASA astronauts splashed down safely in the Gulf of Mexico Sunday for the first time in a commercially built and operated American crew spacecraft, returning from the International Space Station to complete a test flight that marks a new era in human spaceflight.

SpaceX's Crew Dragon, carrying Robert Behnken and Douglas Hurley, splashed down under parachutes in the Gulf of Mexico off the coast of Pensacola, Florida at 2:48 p.m. EDT Sunday and was successfully recovered by SpaceX. After returning to shore, the astronauts immediately will fly back to Houston.

"Welcome home, Bob and Doug! Congratulations to the NASA and SpaceX teams for the incredible work to make this test flight possible," said NASA Administrator Jim Bridenstine. "It's a testament to what we can accomplish when we work together to do something once thought impossible. Partners are key to how we go farther than ever before and take the next steps on daring missions to the Moon and Mars."

Behnken and Hurley's return was the first splashdown for American astronauts since Thomas Stafford, Vance Brand, and Donald "Deke" Slayton landed in the Pacific Ocean off the coast of Hawaii on July 24, 1975, at the end of the Apollo-Soyuz Test Project.

NASA's SpaceX Demo-2 test flight launched May 30 from the Kennedy Space Center in Florida. After reaching orbit, Behnken and Hurley named their Crew Dragon spacecraft "Endeavour" as a tribute to the first space shuttle each astronaut had flown aboard.

Nearly 19 hours later, Crew Dragon docked to the forward port of the International Space Station's Harmony module May 31.

"On behalf of all SpaceX employees, thank you to NASA for the opportunity to return human spaceflight to the United States by flying NASA astronauts Bob Behnken and Doug Hurley," said SpaceX President and Chief Operating Officer Gwynne Shotwell. "Congratulations to the entire SpaceX and NASA team on such an extraordinary mission. We could not be more proud to see Bob and Doug safely back home—we all appreciate their dedication to this mission and helping us start the journey towards carrying people regularly to low Earth orbit and on to the Moon and Mars. And I really hope they enjoyed the ride!"

Behnken and Hurley participated in a number of scientific experiments, spacewalks and public engagement events during their 62 days aboard station. Overall, the astronaut duo spent 64 days in orbit, completed 1,024 orbits around Earth and traveled 27,147,284 statute miles.

The astronauts contributed more than 100 hours of time to supporting the orbiting laboratory's investigations. Hurley conducted the Droplet Formation Study inside of the Microgravity Science Glovebox (MSG), which evaluates water droplet formation and water flow. Hurley also conducted the Capillary Structures investigation, which studies the use of different structures and containers to manage fluids and gases.

Hurley and Behnken worked on numerous sample switch outs for the Electrolysis Measurement (EM) experiment, which looks at bubbles created using electrolysis and has implications for numerous electrochemical reactions and devices. Both crew members also contributed images to the Crew Earth Observations (CEO) study. CEO images help record how our planet is changing over time, from human-caused changes – such as urban growth and reservoir construction – to natural dynamic events, including hurricanes, floods, and volcanic eruptions.

Behnken conducted four spacewalks while on board the space station with Expedition 63 Commander and NASA colleague Chris Cassidy. The duo upgraded two power channels on the far starboard side of the station's truss with new lithium-ion batteries. They also routed power and Ethernet cables, removed H-fixtures that were used for ground processing of the solar arrays prior to their launch, installed a protective storage unit for robotic operations, and removed shields and coverings in preparation for the arrival later this year of the Nanoracks commercial airlock on a SpaceX cargo delivery mission.

Behnken now is tied for most spacewalks by an American astronaut with Michael Lopez-Alegria, Peggy Whitson, and Chris Cassidy, each of whom has completed 10 spacewalks. Behnken now has spent a total of 61 hours and 10 minutes spacewalking, which makes him the U.S. astronaut with the third most total time spacewalking, behind Lopez-Alegria and Andrew Feustel, and the fourth most overall.

The Demo-2 test flight is part of NASA's Commercial Crew Program, which has worked with the U.S. aerospace industry to launch astronauts on American rockets and spacecraft from American soil to the space station for the first time since 2011. This is SpaceX's final test flight and is providing data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft and ground systems, as well as in-orbit, docking, splashdown, and recovery operations. 

Crew Dragon Endeavour will return back to SpaceX's Dragon Lair in Florida for inspection and processing. Teams will examine the spacecraft's data and performance from throughout the test flight. The completion of Demo-2 and the review of the mission and spacecraft pave the way for NASA to certify SpaceX's crew transportation system for regular flights carrying astronauts to and from the space station. SpaceX is readying the hardware for the first rotational mission, called Crew-1, later this year. This mission would occur after NASA certification, which is expected to take about six weeks.

The goal of NASA's Commercial Crew Program is safe, reliable and cost-effective transportation to and from the International Space Station. This could allow for additional research time and increase the opportunity for discovery aboard humanity's testbed for exploration, including helping us prepare for human exploration of the Moon and Mars.

NASA astronaut Chris Cassidy installs fluid research hardware inside the U.S. Destiny laboratory module's Microgravity Science Glovebox.

Free-flying robots, planetary bodies and water droplets were just part of Tuesday's research plan aboard the International Space Station. The Expedition 63 trio also serviced a variety of communications gear and life support systems.

NASA and its international partners are planning human missions to the Moon, Mars and Beyond and the space station represents a big step in that effort. The orbiting lab provides a unique platform to learn about the long-term effects of microgravity on a variety of systems.

A set of cube-shaped, robot assistants are flying around on their own today inside Japan's Kibo laboratory module. Engineers are looking at video and imagery downlinked from the Astrobee devices to understand how the autonomous free-flyers visualize and navigate their way around the station.

Commander Chris Cassidy took a look at dynamic granular material samples this morning that simulate planetary surfaces. The experiment is taking place inside ESA's (European Space Agency) Columbus laboratory module and could inform future planetary exploration missions.

The veteran NASA astronaut also split his time between botany and fluid physics. Cassidy worked on the Plant Habitat-02 checking growth lights and installing an acoustic shield to protect the plants from station noises. Next, he moved onto commercial research to improve water conservation and water pressure techniques on Earth.

In the Russian segment of the station, the two cosmonaut flight engineers worked on their complement of orbital science and lab maintenance. Anatoly Ivanishin serviced video equipment and an air purifier before conducting Earth observations. Ivan Vagner collected air samples for microbial analysis and explored ways to improve interactions between mission controllers, students and space crews.

Russia's Progress 76 resupply ship is pictured docked to the International Space Station's Pirs docking compartment. Below the orbiting lab are the city lights of southeastern Europe.

Advanced space science, cargo transfers and orbital maintenance kept the three Expedition 63 crew members occupied Thursday aboard the International Space Station.

Commander Chris Cassidy spent a good portion of his day working inside JAXA's (Japan Aerospace Exploration Agency) Kibo laboratory module. The experienced shuttle and station astronaut retrieved the Handhold Experiment Platform-2 (HXP-2), packed with several experiments, from inside Kibo's airlock.

The HXP-2 was grappled by Japan's robotic arm, removed from Kibo's Exposed Facility and placed inside the airlock last week. The small research platform housed a variety of experiment samples exposed to the vacuum of space for observation.

Russia's newest resupply ship, the Progress 76 (76P) which delivered nearly three tons of food, fuel and supplies last month, continued to be offloaded today. Cosmonauts Anatoly Ivanishin and Ivan Vagner unpacked electronics gear from the 76P and updated the space station's inventory system.

Ivanishin then moved on to science exploring how bone marrow and enzymes adapt to weightlessness and studied Earth's upper atmosphere. Vagner checked station smoke detectors and transferred waste fluids into the Progress 75 cargo craft.

The sun's first rays burst over the Earth's horizon during an orbital sunrise as the International Space Station orbited above the Indian Ocean southwest of Australia.

Advanced space physics and biotechnology research kicked off the week for the Expedition 63 trio aboard the International Space Station.

Commander Chris Cassidy of NASA started Monday operating a variety of science experiments that observe different microgravity phenomena. He continued researching water droplets in the U.S. Destiny laboratory module to promote water conservation and improve water pressure for space and Earth facilities.

The veteran astronaut, whose first mission was in 2009, also worked in Japan's Kibo laboratory module maintaining the BioLab incubator. He opened up the space biology research device, that houses microbes, tissue cultures and small invertebrates, and checked fans, sensors and relative humidity.

Cassidy also joined his crewmates, cosmonauts Anatoly Ivanishin and Ivan Vagner, for body mass measurements aboard the orbiting lab today. The device uses a Newtonian method that applies a known force to an individual with the resulting acceleration providing a mass calculation in microgravity.

Ivanishin also spent Monday splitting his time between Earth observations and biomedical research. The three-time station visitor photographed global landmarks to observe and forecast the effects of man-made and natural catastrophes. He then moved onto to exploring the survivability of enzymes and bone marrow cells in the weightless environment.

First-time space flyer Ivan Vagner worked all day in the station's Russian segment on biotechnology research. He collected microbe samples from the air and lab surfaces for incubation and analysis to understand and monitor conditions for safe and sterile space research gear.

ЦитироватьISS Daily Summary Report – 8/10/2020

Biological Experiment Laboratory (BioLab):
Спойлер
The crew performed health checks of the BioLab Glovebox seals and gloves including sensors for the fan status, delta pressure, temperature and relative humidity. The BioLab is a multiuser research facility located in the Columbus laboratory. It is used to perform space biology experiments on microorganisms, cells, tissue cultures, small plants, and small invertebrates. BioLab allows scientists to gain a better understanding of the effects of microgravity and space radiation on biological organisms.

Droplet Formation Study:
Спойлер
The crew performed the setup and initiation of recording for additional runs of the DFS investigation and performed any residual water cleanup from the test hardware. Data will be archived by an alternate method which will actually result in a quicker delivery time to the experiment team. This completes this run of tests and the hardware will be stowed. Droplet Formation Studies in Microgravity (Droplet Formation Study) seeks to evaluate the water droplet formation, water flow, and pressure of Delta Faucet's current H2Okinetic shower head technology versus the industry-standard use of jet nozzles. H2Okinetic technology allows better control of droplet size and increases the speed of the drops (fewer water drops are used, but the droplets are larger and are moving faster), which creates a feeling of increased pressure for the end user. The study evaluates how best to control the output of water droplets to create a better performing shower device that provides an improved experience for the end user while also conserving water and energy.

Materials Science Laboratory (MSL):
Спойлер
The crew inserted the calibration cartridge into the MSL to allow ground teams to perform a calibration run on the facility. MSRR Z-book battery was configured for extended life mode. The MSL is used for basic materials research in the microgravity environment of the ISS. The MSL can accommodate and support diverse experiment modules. In this way many material types, such as metals, alloys, polymers, semiconductors, ceramics, crystals, and glasses, can be studied to discover new applications for existing materials and new or improved materials.

Telescience Resource Kit (TReK):
Спойлер
The TReK laptop was powered on to allow ground teams to test out the new PEP R14 Pathfinder software. Operating space hardware still requires a complicated set of computer software, which operations teams on the ground maintain. The Flight Demonstration of TReK is a software package that simplifies the software running on the ISS, benefiting users on Earth. Eventually, TReK software will allow scientists, engineers and students who conduct experiments in space to connect to their experiments through regular Internet connection protocols using the new and improved onboard Ethernet communications recently added to ISS.

Starboard Solar Array Wing (SAW) Imagery:
Спойлер
Today, the crew photographed the inboard SAWs (1A and 3A), the outboard arrays (1B and 3B) and their masts. The photos have been downlinked for team review. The yearly inspection is performed to identify possible structural damage to the solar array components.

Environmental Health System (EHS) Total Organic Carbon Analyzer (TOCA) Water Recovery System (WRS) Sample Analysis & Data Record:
Спойлер
Crew performed an analysis of the water processing assembly (WPA) using the TOCA. The TOCA unit oxidizes organic carbon species present in the water to carbon dioxide gas and measures the concentration using nondispersive infrared spectroscopy. Analysis of the potable water using the TOCA occurs on a weekly basis.

ЦитироватьJapanese Resupply Ship Departs Next Week

Japan's HTV-9 resupply ship is seen with the HTV-8 pallet inside containing old nickel-hydrogen batteries removed during a series of spacewalks earlier this year.

A Japanese resupply ship will depart the International Space Station next week after nearly three months attached to the orbital lab. Meanwhile, the  Expedition 63 crew continued a variety of science operations today.

JAXA, the Japan Aerospace Exploration Agency, announced Tuesday, Aug. 18, as the release date for its H-II Transfer Vehicle-9 (HTV-9) cargo craft. Ground controllers will remotely control the Canadarm2 robotic arm to grapple and remove the HTV-9 from the Harmony module. Commander Chris Cassidy of NASA will command the Canadarm2 to release the cargo craft into space completing an 85-day station mission. The HTV-9 will orbit Earth on its own for two more days and reenter the atmosphere above the South Pacific for a fiery, but safe demise.

The HTV-9 delivered four tons of gear on May 25 that included the new Space Frontier Studio for live broadcasts inside Japan's Kibo laboratory module. Cassidy set up the live-streaming hardware today for an event highlighting science activities inside Kibo.

Cassidy also completed fluid research work that took place inside the U.S. Destiny laboratory module's Microgravity Science Glovebox. The veteran astronaut disconnected, took apart and stowed the hardware that investigated water droplet behavior in microgravity. Results may promote water conservation and improve water pressure for Earth and space systems.

Cosmonaut Anatoly Ivanishin continued working on a long-running Earth observation study on the Russian side the station. That experiment is helping scientists monitor and forecast natural and man-made catastrophes around the world.

Fellow cosmonaut and flight engineer Ivan Vagner worked during the morning testing broadband video communications gear. The first-time space flyer then spent the rest of the afternoon servicing the ventilation subsystem in the Zvezda service module.
