Posted Jun 4, 2019 at 10:18 am


Four spaceships are docked at the space station including Northrop Grumman's Cygnus space freighter and Russia's Progress 72 resupply ship and the Soyuz MS-11 and MS-12 crew ships.

A pair of U.S. and Russian resupply ships have departed at the International Space Station this week. Russia's Progress 71 (71P) cargo craft undocked this morning and the SpaceX Dragon returned to Earth Monday.

The 71P, packed with trash and unused hardware, undocked from the aft end of the Zvezda service module today at 3:40 a.m. EDT. It reentered Earth's atmosphere and safely burned up over a remote portion of the Pacific Ocean. This completes a mission that began when the 71P launched Nov. 16 and delivered almost three tons of cargo two days later to the Expedition 57 crew.

Amidst all the cargo transfers and spaceship departures, the Expedition 59 crew found time for continuing space research. Monday saw astronauts David Saint-Jacques and Christina Koch explore the possibility of fueling satellites in space and separating gases and fluids in advanced life support systems. Flight Engineer Anne McClain cleaned an incubator after the completion of an experiment that observed altered gene expressions occurring in space.

Today, the crew is conducting a variety of biomedical research and space botany.

NASA astronaut Nick Hague examined the eyes of cosmonauts Oleg Kononenko and Alexey Ovchinin today using optical coherence tomography hardware. Saint-Jacques had his leg artery remotely scanned by a doctor on the ground studying cardiovascular health in space.

Koch set up botany hardware today in Europe's Columbus laboratory module for ongoing research into growing a continuous supply of fresh food in space. McClain continued incubator closeout activities in Japan's Kibo laboratory module.

Closing out a 30-day mission, a SpaceX Dragon cargo capsule departed the International Space Station on Monday for a fiery trip back to Earth, culminating in re-entry back into the atmosphere and a parachute-assisted splashdown in the Pacific Ocean southwest of Los Angeles.

The station's Canadian-built robotic arm pulled the Dragon spacecraft from its berthing port on the Harmony module early Monday, and ground controllers in Houston commanded the arm to release the supply ship at 12:01 p.m. EDT (1601 GMT). A series of three thruster firings by the Dragon's Draco control jets pushed the capsule away from the station, setting up for a deorbit burn nearly five hours later.

The deorbit burn set up the Dragon for re-entry, slowing the craft's velocity enough to dip into the atmosphere over the Pacific Ocean. Fitted with a protective heat shield, the capsule plunged back to Earth before deploying a series of parachutes to slow for splashdown in the Pacific Ocean around 202 miles (325 kilometers) southwest of Long Beach, California, at 5:48 p.m. EDT (2148 GMT; 2:48 p.m. PDT).

The unpiloted supply ship returned to Earth with more than 4,200 pounds (1,900 kilograms) of equipment.

SpaceX recovery teams were on station in the Pacific to hoist the capsule aboard a boat for the trip back to the Port of Los Angeles, wh ere time-sensitive human and animal research specimens will be turned over to science teams around the world.

The mission was SpaceX's 17th resupply flight to the space station under a $3.04 billion contract with NASA. The capsule arrived at the orbiting complex May 6, two days after a predawn launch from Cape Canaveral aboard a Falcon 9 rocket.

The automated Dragon cargo capsule delivered 5,472 pounds (2,482 kilograms) to the space station, including a $110 million NASA instrument mounted outside the space station to monitor carbon dioxide in Earth's atmosphere. The cargo mission also carried a payload package sponsored by the U.S. Air Force with experiments in X-ray communications, space-based supercomputing, plasma measurements, and attitude control and determination.

Before re-entering the atmosphere Monday, the Dragon jettisoned its unpressurized trunk to burn up during re-entry with a pair of decommissioned NASA instruments loaded into the external payload bay of the SpaceX cargo craft.

NASA's Cloud-Aerosol Transport System, or CATS, instrument was fastened outside the space station after its delivery on a previous SpaceX cargo mission in January 2015. The CATS instrument measured clouds and tiny particles in the atmosphere that play a role in Earth's climate and weather.

NASA's SCaN Testbed experiment, which arrived at the station in 2012, was also tagged for disposal during re-entry of the Dragon's trunk Monday. During its mission, SCaN Testbed demonstrated the use of software-defined radios for space communications.

SpaceX is gearing up for its next resupply mission to the space station, which is set for launch from Cape Canaveral in July.

Студенты Амурского госуниверситета вышли на связь с космонавтами на МКС
14:57

БЛАГОВЕЩЕНСК, 5 июн - РИА Новости. Студенты "космических" специальностей Амурского госуниверситета (АмГУ) в среду из Амурского центра управления полетами (АЦУП) вышли на связь с российскими космонавтами Олегом Кононенко и Алексеем Овчининым, которые находятся на МКС, рассказал РИА Новости инженер центра Герман Лебедев.

Сеанс начался в 16.50 (10.50 мск), когда, по словам Лебедева, МКС находилась в зоне радиовидимости АЦУП.

"Сеанс длился 10 минут, прошел отлично, была отличная слышимость, студенты успели задать семь вопросов. В том числе спрашивали, каким, по мнению космонавтов, остается срок безопасной эксплуатации МСК. Овчинин и Кононенко ответили, что этим вопросом занимаются наземные службы", - сказал Лебедев РИА Новости.

Собеседник агентства добавил, что в октябре 2018 года на первом сеансе связи из АЦУП студенты спрашивали космонавта Сергея Прокопьева про бытовые условия и эксперименты на МКС.

 Скрытый текст:

В 2009 году АмГУ совместно с Московским авиационным институтом и Южно-Уральским государственным университетом начал готовить инженеров по специальностям "Космические летательные аппараты и разгонные блоки" и "Стартовые и технические комплексы ракет и космических аппаратов", с 2016 года совместно с Самарским национально-исследовательским университетом имени академика Королева идет обучение по направлениям "Ракетные комплексы и космонавтика" и "Проектирование, производство и эксплуатация ракет и ракетно-космических комплексов".

В научно-образовательном центре АмГУ сейчас занимаются созданием спутника формата CubeSat. Первые выпускники университета начали работать на космодроме Восточный в Амурской области в 2014 году.

Первый на Дальнем Востоке Амурский центр управления полетами был открыт на базе инженерно-физического факультета АмГУ 10 апреля 2015 года. Он позволяет осуществлять оперативно-техническое руководство работами по приему телеметрической информации, управлять университетскими малыми космическими аппаратами и проводить радиосвязь с космонавтами.

ISS Daily Summary Report - 6/04/2019

71 Progress (71P) Undock:

 Скрытый текст:

Progress undocked from the Service Module (SM) Aft Port at 3:40 AM CT. After a successful de-orbit burn, the vehicle completed its mission following destructive re-entry over the Pacific Ocean at 7:22 AM CT.

ISS Experience:

 Скрытый текст:

The crew set up the ISS Experience hardware in the Node 1 starboard hatch area. Today's targets included post sleep discussions and a spacesuit scene. The ISS Experience creates a virtual reality film documenting daily life aboard the ISS. The 8 to 10 minute videos created from footage taken during the six-month investigation cover different aspects of crew life, execution of science aboard the station, and the international partnerships involved. It uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

Photobioreactor File Download:

 Скрытый текст:

This is a continuation of the software upd ate troubleshooting efforts. It is hoped that the file downlink will allow verification of a successful software load and pave the way for a successful experiment start later this week. The algae used in the system is expected to start degrading around June 6. Today the life support systems that sustain astronauts in space are based on physicochemical processes. The Photobioreactor aims to demonstrate that microalgae (i.e. biological processes) can be used together with existing systems to improve recycling of resources, creating a hybrid life support system. This hybrid approach could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth, and will first be tested in space on the ISS.

Radi-N2 Deploy:

 Скрытый текст:

The crew retrieved the 8 bubble detectors from the Russian crew and deployed 6 detectors in the CUPOLA, one detector in a crew sleep area sleeping area, and one detector in a pouch to be worn by a crew member for the next 7 days. The objective of this Canadian Space Agency investigation is to better characterize the ISS neutron environment, define the risk posed to the crew members' health, and provide the data necessary to develop advanced protective measures for future spaceflight. It's been recognized that neutrons make up a significant fraction (10-30%) of the biologically effective radiation exposure in low-Earth orbit. The bubble detectors used in the investigation are designed detect neutrons and ignore all other radiation.

Standard Measures:

 Скрытый текст:

The crew completed their postsleep questionnaires and saliva collections and insertion into MELFI. The aim of the investigation is to ensure consistent capture of an optimized, minimal set of measures from crewmembers until the end of the ISS Program to characterize the adaptive responses to and risks of living in space.

Vascular Echo:

 Скрытый текст:

The crew participated in a Vascular Echo science session which included arterial blood pressure measurements and ultrasound scans of the neck, thigh, portal vein and heart. Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) examines changes in blood vessels, and the heart, while crew members are in space, then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crewmember health, and quality of life for everyone.

Veg-04A Experiment:

 Скрытый текст:

The crew se t up and initiated the Veg-04A investigation in the 2 Veggie facilities. Veg-04A is a Human Research Program sponsored experiment which will growMizuna mustard, a leafy green crop, for 28 days under two different light quality treatments. The Pick-and-Eat Salad-Crop Productivity, Nutritional Value, and Acceptability to Supplement the ISS Food System (Veg-04A, Veg-04B, and Veg-05) investigation is a phased research project to address the need for a continuous fresh-food production system in space. A healthy, nutritious diet is essential for long-duration exploration missions, which means that the typical pre-packaged astronaut diet needs to be supplemented by fresh foods during flight; the Veggie Vegetable Production System (Veggie) has begun testing aboard the space station to help meet this need, and validation tests have demonstrated that leafy greens can be grown in spaceflight. The research of Veg-04A focuses on the impact of light quality and fertilizer on leafy crop growth, microbial food safety, nutritional value, taste acceptability by the crew, and the overall behavioral health benefits of having plants and fresh food in space.

Environmental Health System (EHS) Microbial Air and Surface Sampling:

 Скрытый текст:

The crew took surface and air samples for microbial analysis using the Microbial Air Sampler (MAS) and Surface Sample Kit (SSK). These samples will be incubated in Petri dishes, giving medical personnel a gauge of microbial growth in the air and on surfaces of the ISS. The EHS monitors the atmosphere for gaseous contaminants from nonmetallic materials off-gassing, combustion products, and propellants, microbial contaminants from crewmembers and Station activities, water quality, acoustics, and radiation levels.

Eye Exams:

 Скрытый текст:

In preparation for their return to Earth later this month, the 57 Soyuz (57S) crew completed routine Optical Coherence Tomography (OCT) eye exams. OCT is an imaging technique analogous to ultrasound imaging that uses light instead of sound to capture micrometer-resolution, two- and three-dimensional images of tissue; In this case, the objects of interest are the crewmember's eyes. Eye exams are performed regularly onboard to monitor crewmembers eye health which can be affected by long-duration stays in a microgravity environment.

The six-member Expedition 59 crew gathers for a portrait inside of the vestibule between the SpaceX Dragon cargo craft and the Harmony module the day before the commercial space freighter's departure.

The International Space Station residents continued exploring today what living off the Earth for long periods is doing to their body. The Expedition 59 crew also researched ways to improve life in space and even filmed a virtual experience aboard the orbiting lab.

NASA astronauts Nick Hague and Christina Koch took turns serving as Crew Medical Officer during a round of ultrasound eye exams Wednesday morning. The duo scanned the eyes of Commander Oleg Kononenko and Flight Engineers Anne McClain and David Saint-Jacques ahead of their homecoming June 24. Astronauts have reported vision issues during and after their missions. The eye imaging helps doctors understand how microgravity impacts the cornea, lens, optic nerve and the shape of the eyeball.

Saint-Jacques once again had his blood pressure checked and arteries scanned with an ultrasound device to investigate how weightlessness affects the cardiovascular system. Arterial stiffness has been observed in space and the study may help offset the negative effects improving life in space and on Earth. The astronaut from the Canadian Space Agency also recorded a virtual reality video of his biomedical activities for later viewing on Earth.

McClain monitored a small cube-shaped robot called the Astrobee and tested its ability to float around the Kibo laboratory module autonomously. Engineers are assessing the free-flying device's potential to perform routine maintenance duties and provide additional lab monitoring capabilities.

Koch wrapped up the day in Europe's Columbus laboratory module setting up a fluid physics study that has been observing sloshing and waves on the station since 2016. The Fluidics study uses a motorized instrument to slosh fluids in tanks with video and data downlinked to researchers on the ground. Results could optimize the design of satellite fuel systems and increase the understanding of Earth's oceans and climate.

NASA astronaut Nick Hague assembles and installs the Water Storage System inside the U.S. Destiny laboratory module.

The International Space Station's BEAM opened up today for environmental sampling and cargo stowage activities as NASA continues to test the commercial module. The Expedition 59 crew also explored biotechnology and fluid physics to improve Earth applications and space habitability.

Astronauts Anne McClain, Christina Koch and David Saint-Jacques checked out BEAM, the Bigelow Expandable Activity Module, today to sample the air for microbes and stow spare hardware inside. BEAM had its stay at the station's Tranquility module extended in November 2017 after a successful installation and expansion in the spring of 2016. The soft material module is providing extra storage space at the orbiting lab and additional technology demonstrations that may inform future missions.

After the BEAM work, McClain sampled algae grown inside the Photobioreactor to explore the viability of closed, hybrid life-support systems in space. Koch wrapped up a study observing how fluids slosh and wave in space to improve satellite fuel systems and increase knowledge of Earth's oceans and climate.

Flight Engineer Nick Hague spent the majority of Thursday installing Water Storage System components in the U.S. Destiny laboratory module. The space plumbing work consisted of installing a variety of hoses including power and data cables to the main Potable Tank Assembly.

Commander Oleg Kononenko and Alexey Ovchinin started the morning taking breath and blood pressure measurements for a cardiopulmonary study. Next, they tested communication systems in the Soyuz MS-11 crew ship and spent the rest of the afternoon on a variety of Russian science and maintenance activities.

#НовостиИзНевесомости от экипажа МКС-59

На прошлой неделе весь мир следил за выходом в открытый космос Олега Кононенко и Алексея Овичинина. Однако отдыхать нашим космонавтом некогда, рассказываем про дела космической важности, которые происходили на МКС в последние дни. 

На орбитальной станции освободились сразу два «парковочных места». 3 июня от модуля «Гармония» американского сегмента отстыковался грузовой корабль Dragon SpX-17, а на следующий день космонавты закрыли переходные люки модуля «Звезда» и проводили российский «Прогресс МС-10». 

«Космические грузовики» поработали на славу -- доставили для экипажа по несколько тонн необходимого груза (еду, воду, оборудование для научных экспериментов, топливо), а «Прогресс» еще и провел 5 коррекций орбиты МКС: один в 2018 году и четыре -- в 2019 году. 

До возвращения на Землю экипажа Олега Кононенко остается меньше трех недель. Поэтому командир станции и его коллеги Давид Сен-Жак и Энн Макклейн начинают готовить корабль к завершению экспедиции... и себя  

Олег Кононенко специально для наших подписчиков заснял процесс посещения «космического салона», в роли парикмахера выступил Алексей Овчинин. На борту нет каких-то невероятных приспособлений для стрижки -- процесс аналогичен земному, только на машинку надет шланг пылесоса, чтобы волосы не разлетелись по станции.

ISS Daily Summary Report - 6/06/2019

Fluidics:

 Скрытый текст:

As a continuation of the Fluidics session which began on Wednesday, the crew performed 3 additional experiment runs (2A, 2B, 3). The measurement of liquid displacement within a sphere in microgravity relates to a given kinematic representation of a spacecraft's fuel tank. This investigation evaluates the Center of Mass (CoM) position regarding a temperature gradient on a representation of a fuel tank. The observation of capillary wave turbulence on the surface of a fluid layer in a low-gravity environment can provide insights into measuring the existing volume in a sphere.

Fiber Optic Production (FOP):

 Скрытый текст:

As a continuation of the troubleshooting for the FOP system, the crew inspected and cleaned 3 of the ZBLAN preforms, attached new Teflon tails and ins erted one of them into the FOP for a processing attempt. The preforms are cylinders of ZBLAN stock material from which the fiber is drawn after heating. FOP is designed to create optical fibers with high commercial value aboard the ISS using a blend of zirconium, barium, lanthanum, sodium, and aluminum called ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF). It operates within the Microgravity Science Glovebox (MSG). Extensive theoretical studies along with a limited number of experimental studies suggest that ZBLAN optical fibers produced in microgravity should exhibit far superior qualities to those produced on Earth. The resulting optical fiber from Fiber Optic Production is expected to help verify these studies and guide further engineering efforts to manufacture high value optical fiber in large volume aboard the ISS.

HELIOS (Hardened Extremely Long-life Information in Optical Storage):

 Скрытый текст:

As part of the Bigelow Expandable Activity Module (BEAM) ingress today, the HELIOS hardware was transferred to the BEAM and stowed. HELIOS tests whether a data storage medium is resistant to space radiation. It contains samples of the media, which is applied to a glass substrate, and stowed in this location for approximately 6 months. On Earth, the atmosphere protects humans and electronics from radiation that, in space, can damage electronics, including memory devices such as hard drives and memory disks. This technology, similar to that used in early photography, could replace conventional solid state memory for recording critical data on spacecraft.

ISS HAM Pass:

 Скрытый текст:

Today the crew participated in an ISS HAM pass with Moriah Central School, Port Henry, NY USA. This is a K-12 public school with nearly 800 students and 50 teachers. Some of the questions the students asked involved the purpose and val ue of the ISS, types of computers and operating systems used by the crew on ISS, favorite science experiment on ISS, and many more. ISS Ham Radio provides opportunities to engage and educate students, teachers, parents and other members of the community in science, technology, engineering and math by providing a means to communicate between astronauts and the ground HAM radio units.

PBR (Photobioreactor):

 Скрытый текст:

Following some past difficulties, which were corrected with a software update, today the crew filled the PBR hardware with medium and algae to begin the experiment. The life support systems that sustain astronauts in space are based on physicochemical processes. The Photobioreactor investigation aims at demonstrating that microalgae (i.e. biological processes) can be used together with existing systems to improve recycling of resources, creating a hybrid life support system. This hybrid approach could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth.

Water Storage System (WSS) Assembly Part 2:

 Скрытый текст:

In May, the crew installed shelf panels, ground straps, and rack internal power/data cables after rotating the Zero-G Stowage Rack (ZSR) shell at the LAB1D4 location. Rack rotation took longer than expected and several tasks had to be deferred. Today the crew completed the remaining tasks. WSS will add new capabilities to the existing Environmental Control and Life Support System. (ECLSS) Water Recovery and Management System (WRM) by providing an additional 75 liters of iodinated water storage as well as new methods of transporting water in the potable waterbus.

Bigelow Expandable Activity Module (BEAM) Hardware Transfer:

 Скрытый текст:

The crew gathered hardware from the Permanent Multipurpose Module (PMM) to be stored in BEAM. After a successful ingress of the module, they retrieved the failed T2 treadmill Remove and Replaced (R&Rd) last month for disposal on NG-11 and swapped various stowage to increase accessibility to key on-orbit spare hardware. The crew also took surface and air samples of the BEAM module for environmental analysis and stowed the hardware removed from BEAM after egressing the module.

In Flight Maintenance (IFM) Hatch Guide Installation:

 Скрытый текст:

After the crew had ingressed BEAM, a Hatch Handle Guide Ring was installed onto the Node 3 Aft hatch. Designed to prevent the Hatch Handle from being stowed incorrectly, this guide was developed to prevent the crew from inadvertently isolating themselves from their return vehicle.

H-II Transfer Vehicle (HTV) 8 Proximity Communication System (PROX) Checkout:

Today the crew configured the PROX system for an initial set of systems checkouts in preparation of the upcoming HTV 8 mission in September. HTV missions use the PROX system for communication between HTV and ISS. Crew commanding to HTV via PROX utilizes a Portable Computer System (PCS) version of the Hardware Command Panel (HCP).

Астронавты на МКС установили знаки для покидания станции в случае аварии
16:17

МОСКВА, 7 июн - РИА Новости. Астронавты завершили установку внутри модулей американского сегмента МКС светящихся указателей, которые в случае аварии помогут им найти спасательный корабль для эвакуации со станции, сообщило НАСА.

На сайте НАСА отмечается, что на днях экипаж МКС завершил установку фотолюминесцентных знаков в модуле Harmony. В будущем такие маркеры в случае аварии на станции и при отсутствии света укажут астронавтам путь к американским пилотируемым кораблям для покидания МКС.

В настоящее время на борту МКС находится экипаж из россиян Олега Кононенко и Алексея Овчинина, американцев Энн Макклейн, Ника Хейга и Кристины Кук, а также канадца Давида Сен-Жака.

Сейчас в США создаются пилотируемые космические корабли: Starliner - компанией Boeing, Crew Dragon - компанией SpaceX. В марте корабль Crew Dragon совершил первый испытательный беспилотный полет на МКС. В августе намечается первый испытательный беспилотный полет корабля Starliner на МКС. До конца 2019 года планируются первые полеты кораблей Starliner и Crew Dragon с экипажем на борту.

This view from the International Space Station looks from northeast to southwest, from Greece, Italy and across the Mediterranean Sea to Libya. The Soyuz MS-12 spacecraft is pictured in the foreground.

Four Expedition 59 astronauts are taking a three-day weekend aboard the International Space Station after packing a U.S. space freighter for return to Earth. The two cosmonauts focused on exercise studies, physics research and life support maintenance on the Russian side of the orbiting lab.

NASA astronauts Christina Koch, Anne McClain and Nick Hague and Canadian Space Agency astronaut David Saint-Jacques are relaxing today following last weekend's SpaceX Dragon cargo loading and closeout activities. The quartet spent the first part of the week cleaning and stowing hardware after Dragon returned to Earth Monday full of completed experiments and station gear for analysis.

Station Commander Oleg Kononenko attached sensors to Flight Engineer Alexey Ovchinin today monitoring his vital signs during an exercise study to determine the most effective workouts in space. Ovchinin cleaned up afterward then researched plasma crystals, or highly charged micro-particles that form self-organized structures in microgravity. The duo also checked life support systems, configured communications gear and inspected the structural integrity of the station's Russian segment.

NASA releases ISS commercialization plan

WASHINGTON -- NASA unveiled a multi-pronged effort June 7 to increase commercial use of the International Space Station, from changes in policy to making a docking port available for commercial modules.

The plan, announced at an event at the Nasdaq stock exchange in New York, is the latest push by NASA to encourage both increased commercial use of the ISS while building up a supply of commercial facilities that could eventually succeed the station.

"We need to think of a different way of doing business," said Bill Gerstenmaier, NASA associate administrator for human exploration and operations. "We have no idea what kinds of creativity and literally out-of-this-world ideas can come from private industry."

The initiative announced by NASA features five elements. One is a new commercial use policy for the station that will allow activities ranging from manufacturing to marketing to take place on the station. That includes a pricing schedule for cargo to and from the station and services there.

Those activities must fall into one of three categories, said Robyn Gatens, deputy director of the ISS program at NASA Headquarters: a "connection" to NASA's mission, stimulation of the LEO economy or needs to make use of the unique environment of microgravity.

NASA will also allow commercial crew providers to transport private astronauts to the station. The agency will allow two such astronauts per year on the station for missions no longer than 30 days each. Those astronauts will be charged about $35,000 per day by NASA for use of station resources, like life support, as well as the fees charged by the companies arranging the flights.

NASA plans to release a long-awaited solicitation to give companies access to a docking port on the Harmony module of the station to which they could attach a commercial module. That request for proposals, part of NASA's Next Space Technologies for Exploration Partnerships (NextSTEP) program, will be released June 14, and Gatens said NASA expects to sel ect a company by the end of the year. A separate NextSTEP solicitation, to be released on July, will focus on studies of free-flying commercial space stations.

NASA had discussed offering that port to companies as far back as 2016, but held off on a formal solicitation until now. Gerstenmaier said the upcoming competition is informed by studies that NASA awarded last year to a dozen companies examining LEO commercialization concepts, and why it was now rolled into this broader initiative.

"We thought it was important that, rather than doing this piecemeal, one at a time, it was good to put it all together," he said. "It took us a little bit of time to get that all together."

The final two elements of the initiative focus on demand. NASA will seek proposals for studies on commercial uses of the station as well as identification of "real and perceived" barriers to using the station. It also released a forecast of its minimum long-term demand for services and activities in LEO.

NASA is encouraging greater commercial use of the station as part of a long-term vision that sees a gradual transition from the ISS to commercial space stations, of which NASA would be one of many customers. That would, in turn, free up NASA resources for its exploration plans, such as returning humans to the moon.

NASA, though, has backed away from proposals last year to end direct federal funding of the ISS by 2025. The end of station is less certain now, although there have been efforts in Congress to extend NASA's authorization to operate the station through 2030.

The main principle in NASA's eventual transition fr om the ISS, Gatens said, "is that there will be no gap in human spaceflight in low Earth orbit." With this new initiative, "we're hoping that new capabilities can develop that can one day take over for the space station, and we will begin to do that transition when those capabilities become available."

This approach, though, still leaves open questions about commercial utilization of the ISS. One issue is whether companies that perform research on the station can retain all their intellectual property (IP). "We think there's enough protection there" in the new policy, Gerstenmaier said.

However, Mike Gold, chairman of the regulatory and policy committee of the NASA Advisory Council, said that the policy alone likely can't address all industry concerns about IP rights, as NASA can't waive the IP rights for other federal government agencies. His committee has raised that issue in their previous work, including at the council's most recent meeting May 31.

"It has substantial chilling effects," he said, particularly for those in the pharmaceutical industry. He said he hopes that an upcoming NASA reauthorization act will include language resolving those concerns.

Gerstenmaier said that NASA will be open to change policies or pricing in response to industry input. "This is the beginning of us actively starting an open dialogue with industry to figure out how we can open up space to commercial activities."
