A commercial Cygnus supply freighter set for launch Monday will transport a motley mix of experiments to the International Space Station, helping scientists engaged in a range of research disciplines from studying the birth of the solar system to helping astronauts survive marathon missions in space.<\/p>\n

Materials carried aboard the Cygnus supply ship include a high-resolution camera to detect meteors from the space station, a study to measure blood flow from the brain to the heart in astronauts, and an array of experiments from grade school and university students, officials said Sunday.<\/p>\n

About one-third of the nearly 5,000 pounds of cargo stowed inside the craft\u2019s pressurized cabin will go toward scientific endeavors, according to Camille Alleyne, NASA\u2019s assistant space station program scientist.<\/p>\n

The rest of the supplies will sustain the space station and its crew with spare parts, tools, food, clothes and other essential gear.<\/p>\n

Owned and operated by Orbital Sciences Corp., the Cygnus spacecraft is set for launch at 6:45 p.m. EDT (2245 GMT) from the Mid-Atlantic Regional Spaceport at Wallops Island, Va.<\/p>\n

The unpiloted cargo carrier will take off on top of Orbital\u2019s expendable two-stage Antares rocket. Named SS Deke Slayton in honor of the Mercury astronaut, Cygnus is due to arrive at the space station Nov. 2 after an automated laser-guided final approach.<\/p>\n

Its docking with the space station will punctuate a busy week of comings-and-goings at the outpost.<\/p>\n

A commercial Dragon cargo spacecraft operated by SpaceX departed the space station Saturday and splashed down in the Pacific Ocean, returning more than 1.6 tons of research specimens and hardware items to Earth for analysis and refurbishment.<\/p>\n

Russia\u2019s Progress M-24M supply ship was scheduled to undock from the space station early Monday with trash tagged for disposal during a destructive re-entry over the Pacific Ocean, just as another Progress logistics vehicle was readied for rollout to a launch pad in Kazakhstan for liftoff Wednesday in pursuit of the complex.<\/p>\n

Once the next Progress spacecraft docks to the station a few hours after its launch Wednesday, Orbital\u2019s Cygnus spacecraft will be cleared to rendezvous with the orbiting research laboratory.<\/p>\n

The series of four arrivals and departures in eight days represents a particularly busy period for traffic at the space station, but officials said a regular cadence of resupply missions is indicative of the station\u2019s scientific utility.<\/p>\n

Unmanned supply ships from Orbital and SpaceX, along with the international ATV and HTV spacecraft from Europe and Japan, collectively replace much of the cargo capacity lost with the retirement of the space shuttle.<\/p>\n

\u201cWithout the shuttle, we need all these vehicles coming and going in order to support the research on-board and to keep the crew healthy and well-sustained,\u201d said Frank Culbertson, Orbital\u2019s executive vice president of advanced programs and a former NASA astronaut. \u201cIt is a logistics problem as well as an operational problem for the program to solve, but that\u2019s part of what we do in the space program as we continue to increase capabilities.\u201d<\/p>\n

Monday\u2019s launch is the third operational resupply flight to the space station managed by Orbital Sciences. Known as Orb-3, the mission will be the ninth commercial cargo delivery by Orbital and SpaceX, including demonstration flights.<\/p>\n

\u201cAs they have demonstrated, they are very capable of bringing all the cargo needs that the station has,\u201d said Gerald Esquivel, NASA\u2019s Cygnus integration manager. \u201cThe HTV and the ATV vehicles provide some other unique capabilities, but getting the day in and day out needs met with our commercial providers has been key, and we see that continuing on with our future contracts, as well as eventually when we go with crew transport.\u201d<\/p>\n

\u201cIt\u2019s gratifying to see it all going so well,\u201d said Culbertson, who lived on the space station for four months in 2001.<\/p>\n

\u201cI think it\u2019s a testament to both the program as well as the suppliers than we can interweave all these capabilities, coordinate between the various entities and international partners, and still keep it flowing fairly smoothly and keep the research going,\u201d Culbertson said. \u201cI think you\u2019ll see even more complicated scenarios in the future as we go forward and try to move beyond low Earth orbit.\u201d<\/p>\n

Once the Cygnus mission gets to the station Nov. 2, astronauts will open hatches leading to the spacecraft\u2019s pressurized cargo module \u2014 built by Thales Alenia Space in Italy \u2014 and unpack its contents.<\/p>\n

The cargo load features more than two dozen small CubeSats for deployment outside the space station, a Japanese experiment to gauge the performance of materials in space for future use on solar sails, and investigate the impact of space travel on the human immune system.<\/p>\n

Astronauts will mount a camera system from the Southwest Research Institute on an Earth-facing window in the space station\u2019s Destiny laboratory to look at meteors streaking through the atmosphere below.<\/p>\n

The experiment will mark the first detailed space-based observations of meteors from space.<\/p>\n

\u201cThis analysis will include characterizing the size, the density and the chemical composition of the meteors,\u201d Alleyne said. \u201cInvestigating these compositions of the meteors adds to our understanding of how planets are developed. Continuous measurements of the meteors\u2019 interaction with Earth\u2019s atmopshere also can spot previously unseen meteor [showers].\u201d<\/p>\n

A contribution from the Italian Space Agency, or ASI, will study the blood flow between the brain and heart in microgravity. A special neck collar worn crew space station crew members will collect the data.<\/p>\n

\u201cUnderstanding this blood flow makes it possible for researchers to develop countermeasures to treat headaches and other neurological symptoms that have been reported by crew members living on the space station,\u201d Alleyne said.<\/p>\n

The experiment, dubbed Drain Brain, could also help doctors on the ground develop screening tests for cognitive disorders like Alzheimer\u2019s disease, according to Alleyne.<\/p>\n

Eighteen student teams from California, Louisiana, Michigan, Missouri, New Jersey, New York, South Carolina, Tennessee, Texas, Washington, D.C., and British Columbia also have payloads launching Monday.<\/p>\n

Ranging from fourth-graders to college juniors, the students worked on experiments involving the growth of bacteria and crystals, the development of mosquitos in microgravity, the response of shrimp to space, and the effectiveness of composting in orbit.<\/p>\n

The students also provided payloads with soybean seeds and chia plants to measure how their behavior changes in space.<\/p>\n

The student payloads are managed by the Student Spaceflight Experiments Program, a non-profit which partners with private sector financial backers, including the Center for the Advancement of Science in Space and Subaru of America Inc.<\/p>\n

Items aboard the Cygnus spacecraft\u2019s Orb-3 mission needed for upkeep of the space station include a high-pressure nitrogen tank designed to help revitalize the air inside the complex, keeping the atmosphere similar to Earth\u2019s.<\/p>\n

The nitrogen \u2014 stored at 6,000 psi inside a high-pressure gas tank \u2014 will be transferred to reservoirs outside the space station\u2019s Quest airlock.<\/p>\n

A jetpack that could be used to rescue an astronaut who got detached from the space station during a spacewalk is also inside the Cygnus spaceship, along with a data recorder to be packed inside a European Space Agency Automated Transfer Vehicle when it burns up in Earth\u2019s atmosphere early next year.<\/p>\n

Provided by the Aerospace Corp., the data recorder will measure the conditions the ATV encounters as it falls back to Earth, then transmit its findings back to engineers via satellite before hitting the ocean.<\/p>\n

NASA and ESA officials are devising a special re-entry plan for the end of the ATV mission to gather data and prepare for the destruction of the space station itself when it concludes its operational lifetime some time in the 2020s.<\/p>\n
