© EPA/NASA
НЬЮ-ЙОРК, 20 июня. /Корр. ТАСС Игорь Борисенко/. Космический грузовой корабль Dragon компании SpaceX, доставивший 6 июня 2,7 тонны груза на Международную космическую станцию, будет отстыкован от МКС 2 июля. Об этом сообщил в беседе по телефону с корреспондентом ТАСС представитель пресс-службы Центра космических полетов имени Джонсона в Хьюстоне (штат Техас) Дэниел Хот.
"Отстыковка произойдет 2 июля в 11:43 по времени восточного побережья США (18:43 мск)", - сообщил он. Dragon, как ожидается, на парашютах приводнится в Тихом океане у побережья Калифорнии.
Корабль был запущен с помощью ракеты Falcon 9 с космодрома на мысе Канаверал (штат Флорида). Помимо продовольствия на борт МКС доставлены материалы для проведения более 250 научных экспериментов, в том числе для работ в рамках совместного проекта NASA и Европейского космического агентства (ЕКА) по изучению влияния света и микрогравитации на семена растений, а также для эксперимента для изучения процесса горения газообразных веществ в условиях невесомости. Такие эксперименты нацелены на улучшение эффективности топлива и снижение образования вредных для экологии продуктов его сгорания. Отдельный опыт будет посвящен изучению степени воспламеняемости различных современных материалов и в том числе ориентирован на повышение противопожарной безопасности на борту МКС.
Грузовик также доставил на станцию прибор SEXTANT (Station Explorer for X-Ray Timing and Navigation). Он предназначен для измерения периодичности рентгеновского электромагнитного излучения нейтронных звезд и испытания новейшей технологии навигации.
Сейчас на борту МКС работают российский космонавт Федор Юрчихин, американские астронавты Джек Фишер и Пегги Уитсон.

NASA Science to Return to Earth aboard SpaceX Dragon Spacecraft

SpaceX's Dragon cargo spacecraft is scheduled to splash down in the Pacific Ocean on Sunday, July 2, west of Baja California, with more than 4,100 pounds of NASA cargo, science and technology demonstration samples fr om the International Space Station.

Спойлер

The Dragon spacecraft will be taken by ship to Long Beach, wh ere some cargo will be removed immediately for return to NASA. Dragon then will be prepared for a return trip to SpaceX's test facility in McGregor, Texas, for final processing.

A variety of technological and biological studies are returning in Dragon. The Fruit Fly Lab-02 experiment seeks to better understand the effects of prolonged exposure to microgravity on the heart. Flies are small, with a well-known genetic make-up, and age rapidly, making them good models for heart function studies. This experiment could significantly advance understanding of how spaceflight affects the cardiovascular system and could help develop countermeasures to help astronauts.

Samples from the Systemic Therapy of NELL-1 for osteoporosis will return as part of an investigation using rodents as models to test a new drug that can both rebuild bone and block further bone loss, improving crew health. When people and animals spend extended periods of time in space, they experience bone density loss, or osteoporosis. In-flight countermeasures, such as exercise, prevent it from getting worse, but there isn't a therapy on Earth or in space that can restore bone density. The results from this ISS National Laboratory-sponsored investigation is built on previous research also supported by the National Institutes for Health and could lead to new drugs for treating bone density loss in millions of people on Earth.

The Cardiac Stem Cells experiment investigated how microgravity affects stem cells and the factors that govern stem cell activity. The study focuses on understanding cardiac stem cell function, which has numerous biomedical and commercial applications. Scientists will also look to apply new knowledge to the design of new stem cell therapies to treat heart disease on Earth.

Dragon is the only space station resupply spacecraft able to return a significant amount of cargo to Earth. The spacecraft lifted off from Launch Complex 39A at NASA's Kennedy Space Center in Florida on June 3 carrying about 6,000 pounds of supplies and scientific cargo on the company's eleventh commercial resupply mission to the station.

For more than 16 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 2,000 research investigations from researchers in more than 95 countries.

After delivering about 6,000 pounds of cargo, a SpaceX Dragon cargo spacecraft is set to leave the International Space Station on Sunday, July 2. NASA Television and the agency's website will provide live coverage of Dragon's departure beginning at 11:15 a.m. EDT.

Flight controllers will use the Canadarm2 robotic arm to detach the Dragon capsule, which arrived at the station June 5, from the Earth-facing side of the station's Harmony module. After they maneuver Dragon into place, Expedition 52 Flight Engineers Jack Fischer and Peggy Whitson of NASA will command release of the spacecraft at 11:38 a.m.

Dragon's thrusters will be fired to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn. The capsule will splash down about 5:16 p.m. in the Pacific Ocean. Deorbit burn and splashdown will not air on NASA TV.

Recovery forces will retrieve the capsule and its more than 4,100 pounds of returning cargo, including science samples from human and animal research, biotechnology studies, physical science investigations and education activities. NASA and the Center for the Advancement of Science in Space, the nonprofit organization that manages research aboard the U.S. national laboratory portion of the space station, will receive and process research samples, ensuring they are distributed to the appropriate facilities within 48 hours of splashdown.

In the event of adverse weather conditions in the Pacific, the backup departure date is Monday, July 3, with NASA TV coverage beginning at 2 a.m. and spacecraft release at 2:28 a.m.

Dragon, the only space station resupply spacecraft able to return to Earth intact, launched June 3 on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA's Kennedy Space Center in Florida, for the company's 11th NASA-contracted commercial resupply mission to the station.

Dragon SpX-11 targets Pacific Landing on Monday to return valuable ISS Science
July 2, 2017

The SpaceX Dragon is working towards a Monday homecoming after a very busy cargo-delivery mission to the International Space Station that brought plenty of experiments for the crew to perform as well as three high-profile external payloads, two of which have taken residence on the Station while one was jettisoned overboard.

Dragon's parachute-assisted splashdown landing in the Pacific Ocean was pushed fr om an original target of Sunday due to unfavorable sea states in the offshore landing area. The one-day delay provides time for weather to improve and the natural shift of the Space Station's orbit also moves the landing zone closer to shore, aiming for a box 420 Kilometers south west of the Californian coast line.

Per the revised plan, Dragon will depart the Space Station at 6:41 UTC Monday morning, embarking on several hours of free flight before firing up its Draco thrusters for a ten-minute braking maneuver to drop out of orbit, aiming for re-entry over the Pacific to set up for what is hoped to be another pin-point landing by the spacecraft, enabling a fast recovery and return to shore. The Dragon is loaded with close to two metric tons of science samples and performed experiments that scientists are eager to get their hands on as soon as possible after splashdown.

Dragon takes flight atop Falcon 9 – Photo: SpaceX

The eleventh regular Dragon mission started back on June 3 with a successful launch atop a Falcon 9 rocket, marking the 100th liftoff from Kennedy's Launch Complex 39A, the former on-ramp to the Moon and launch site for the majority of Shuttle missions. Dragon SpX-11 is the first re-use mission for the SpaceX Dragon, employing the C106 spacecraft that visited ISS back in September 2014 on the SpX-4 mission and underwent refurbishment after returning, continuing SpaceX's drive to implement re-usability across its rocket and spacecraft fleet.

The refurbishment process between Dragon's two missions included the replacement of a number of components like the heat shield, some external panels, avionics boxes and other equipment for which lifetime concerns existed. The pressure vessel, thrusters and general majority of systems remained unchanged between the two missions and SpX-11 acted as a validation for future re-use missions that will enable SpaceX to close down Dragon 1 production and focus on the Dragon 2 vehicle that will take over cargo missions after the Commercial Resupply Services 1 contract round and also fly in a crewed configuration as part of NASA's Commercial Crew Program.

Loaded with 2,708 Kilograms of cargo, Dragon arrived in the vicinity of the Space Station two days after launch, approaching ISS from directly below for a robotic capture by the Station's Canadarm2. Dragon was bolted in place on the Harmony module later that day and was opened for business by the crew to access 1,665kg of pressurized cargo delivered by the Dragon.

It was a busy month for Peggy Whitson and Jack Fischer who are currently holding up the fort aboard the U.S. Segment of the Station. They had plenty of cargo to move over to ISS and their plan included dozens of experiments that rode uphill on the Dragon and were planned to return aboard the same spacecraft after being performed in orbit.

Within two days of Dragon's arrival, the crew transferred 40 mice to their residence on ISS to participate in the fifth Rodent Research experiment which studies a novel drug that promises to halt or even reverse bone loss encountered by astronauts in space and patients with Osteoporosis on Earth. Twenty of the mice were loaded back into Dragon for return to Earth, the first live mice to return under Rodent Research to check their post-flight progress. Their former companions are not as lucky and get to live in orbit for another five weeks before being euthanized for future return to Earth.

The crew also set up Fruit Fly Labs on ISS holding thousands of flies that are part of an experiment using the flies as model organisms to examine the effect of microgravity on human heart function. Fischer and Whitson also activated crystallization studies, student payloads, stem cell research and DNA experiments.

Operations were equally busy outside the International Space Station with the Station Robots, the 18-meter long Canadarm2 and the two-armed Dextre, in action for the better part of the four-week stay to deal with the three external payloads on the Dragon Spacecraft.

First to be pulled out of the Dragon Trunk Section was MUSES, the Multi-User System for Earth Sensing – a high-fidelity articulated bench that can hold four Earth-pointed instruments for easy 'plug-and-play' installation & removal while providing payloads with electrical connectivity, data handling and precise Earth pointing. Developed by Teledyne Brown, MUSES was installed June 6 through June 10 on Express Logistics Carrier 4, establishing a new prime Earth-watching facility on ISS for high-resolution imagers, spectrometers, magnetic sensors and various other payloads.


NICER completes initial checkouts – Photo: NASA TV

Next up was NICER – the Neutron-Star Interior Composition Explorer, a high-profile X-ray observatory that will collect precise spectral and timing data on ultra-dense Neutron Stars to reveal their internal composition and uncover mechanisms for dynamic phenomena like ultra-energetic particle acceleration at Neutron Stars.

NICER took its position on ELC4 Site 2 on June 14 and was deployed on June 16 after overcoming initial trouble with its launch locks. After range of motion checks with its large Optical Bench, NICER headed into initial calibration measurements that will continue into mid-July before the instrument begins its science phase of at least two years.

The last item to be moved out of Dragon's Trunk was ROSA – the Roll Out Solar Array, a technology demonstration of a new type of deployable solar array that could be the answer for the power-hungry satellites of the future.

Beginning its pathfinder mission, ROSA was unrolled on June 18 for a weeklong checkout looking at structural dynamics, power characteristics and thermal behavior to retire risks for future satellite missions. When ROSA failed to lock back in its retracted position, a prepared Plan B went into motion and the deployed array was jettisoned from its attachment mechanism on June 26 to undergo a natural orbital decay over a period of months; the Active FRAM was placed back into the Dragon trunk and will be disposed of on Monday via re-entry.

With Dragon's stay on ISS winding down, the crew was in charge of final cargo loading this week with an estimated 1,860kg of hardware returning aboard the Dragon, including one Animal Transporter with 20 lucky mice, the Fruit Fly Lab and four Polar freezers with various experiments including stem cell research. Dragon missions are a welcome opportunity to empty the Station's laboratory freezers that hold everything from crew members' bodily fluids, rodent organs to plant parts. Dragon will be carrying hundreds of tubes of blood, urine and saliva from the crew to support various studies looking into how the body responds to prolonged exposure to space.

Dragon was buttoned up on Sunday with the crew closing the hatch to the spacecraft and going through the usual process to outfit the cavity between ISS and Dragon by removing power/data jumpers and installing drive controllers for the berthing mechanism bolts. Leak checks were completed once the ISS hatch was shut to clear the way for an overnight unberthing for an early morning release.

Four sets of four bolts will be driven followed by the opening of four capture latches to free the Dragon, giving Canadarm-2 full control of the vehicle for a ground-controlled maneuver to the release position. Jack Fischer and Peggy Whitson will take over from ROBO controllers after an early wake up time to support the release of the spacecraft, scheduled for 6:41 UTC with snares releasing the craft's grapple fixture and Canadarm2 retreating to a safe distance.

Recovering from Free Drift, the Dragon will make an initial departure burn three minutes after release to depart ISS along the R-Bar or radial vector. Another short pulse of the Draco thrusters comes 90 seconds after the first maneuver to accelerate Dragon's departure along the R-Bar.

Once outside the Keep Out Sphere, Dragon will make its third and largest departure maneuver to depart the Approach Ellipsoid, pulling out in front of ISS to enter a five-hour free flight toward a rocket-powered braking maneuver to drop out of orbit.

One of the critical events of the Free Flight is the closure of the GNC Bay Door to protect the navigation sensors inside from the harsh re-entry environment. Firing the Draco thrusters for around ten minutes, Dragon will be slowed by around 100 meters per second, placing it on a path toward the dense atmosphere for a fiery re-entry.

Four minutes before hitting the atmosphere, Dragon will drop its Trunk Section, disposing of the solar arrays and trunk via destructive re-entry. During the Re-Entry Process, Dragon's PICA-X Heat Shield has to withstand temperatures of up to 1,600°C, making use of an adaption of NASA's phenolic impregnated carbon ablator heat shield.

About 10 minutes before Splashdown, at an altitude of 13.7 Kilometers, Dragon opens its dual Drogue Chutes slowing the vehicle down for the opening of the three orange-and-white main chutes around three Kilometers in altitude. Flying under the Main Chutes, Dragon is slowed to its landing speed of 17 to 20 Kilometers per hour.

Splashdown is expected 420 Kilometers south-west of the Californian Coast wh ere recovery forces will be awaiting the arrival of the vehicle. In previous cases, Dragon's landing was very close to the bulls-eye target, allowing teams on the recovery ships to track a large portion of the vehicle's descent under its three main parachutes.

After being recovered from the ocean, Dragon will be brought to the Port of Long Beach for initial post-saving steps and the removal of time-critical cargo from the spacecraft. Critical cargo retrieved from Dragon will be shipped back to NASA within 48 hours of landing for post-flight analysis and distribution to the participating scientific institutions.
