The International Space Station has two new NASA astronauts after the SpaceX Crew Dragon arrived on Sunday. The newly-expanded Expedition 63 crew will now be ramping up microgravity research in the coming days and weeks.

NASA astronauts Doug Hurley and Bob Behnken are getting up to speed with space station systems and operations on their first full day as Expedition 63 crewmates. The duo is also unpacking the Crew Dragon vehicle today and integrating its systems with the space station.

The duo joined NASA Commander Chris Cassidy, who has been on orbit since April 9, for a news conference today and talked about the historical nature of the first crewed Dragon mission. Hurley and Behnken, who each flew on two space shuttle missions, also described the differences between the Dragon crew ship and the now-retired shuttles.

Cassidy primarily spent Monday on ongoing lab maintenance activities. The veteran astronaut, who also flew on two previous shuttle missions, serviced research hardware and plumbing gear throughout Monday.

The two Roscosmos cosmonauts, Anatoly Ivanishin and Ivan Vagner, focused on science and routine operations in the Russian segment of the orbiting lab. They joined their NASA crewmates in the morning to review Crew Dragon emergency procedures. Afterward, the duo explored advanced Earth photography techniques and ways to improve space exercise.

ISS Daily Summary Report – 6/02/2020

Combustion Integration Rack/Advanced Combustion via Microgravity Experiments (CIR/ACME):

Спойлер

In a continuation of the s-Flame part 2 investigation, the crew performed the necessary activities to change out a mass flow controller and igniter. The mass flow controller allows the ACME experimenters to study combustion under different gas flow regimes. The igniter was changed from a well-used hoop style igniter to a coil style igniter which can deliver more energy to ignite a gas mixture. A minor leak was seen in one of the coolant Quick Disconnect (QD) fittings when it was removed, but this is not expected to be an issue once installed again. The purpose of s-Flame is to advance our ability to predict the structure and dynamics, including extinction and instabilities, of both soot-free and sooty flames. The results may contribute to the development of lean-burn engines for improved efficiency and reduced pollutant emissions here on Earth. S-Flame is one of five experiments hosted by CIR/ACME which is designed to study gaseous flames.

The newly-expanded Expedition 63 crew with NASA astronauts (front row, from left) Bob Behnken and Doug Hurley. In the center, in the back row, is NASA Commander Chris Cassidy flanked by Roscosmos Flight Engineers (from left) Anatoly Ivanishin and Ivan Vagner.

The three NASA astronauts and two Roscosmos cosmonauts that comprise the Expedition 63 crew are keeping the International Space Station humming with space research.

Less than a week into their stay on the orbiting lab, Flight Engineers Doug Hurley and Bob Behnken are still orienting themselves with station systems and operations. Meanwhile, the duo is beginning to step up their advanced science activities to benefit people on and off Earth.

Hurley is getting up to speed with a pair of space physics experiments today. He started research today on space bubbles and microfluids to improve oxygen and medicine delivery systems. He then photographed hardware being set up to research how tiny particles behave in fluids. Results could improve the development of advanced materials and 3D printing techniques.

Behnken is studying how to remove and re-install a plant habitat so he can access and replace life support gear on Thursday. He also tested the SpaceX Crew Dragon's wi-fi system that connects the spacecraft's portable computer tablets.

Both astronauts also joined NASA Commander Chris Cassidy on Wednesday afternoon reviewing station safety procedures and equipment. Cassidy spent the morning setting up science gear that Hurley would later use to begin his space bubbles research.

In the Russian segment of the station, cosmonauts Anatoly Ivanishin and Ivan Vagner split their time between Earth observations, radiation checks and module inspections. The duo also videotaped messages and station activities for audiences on the ground.

The crew installed the EM experiment hardware in the Microgravity Science Glovebox (MSG) and the investigation was initiated. Electrolytic Gas Evolution Under Microgravity (Electrolysis Measurement) examines the influence of gravity on electrolytic gas evolution, a complex electrochemical process with multiple applications on Earth and in space. For example, electrolysis generates bubbles that can be used to create pressure differentials in microfluidic devices, such as skin patches, used to deliver medications. Microgravity makes it possible to single out bubble growth and study its effect on the process.

Для полета на МКС на корабле Маска выбрали первых туристов
МОСКВА, 4 июн - РИА Новости. Первые три туриста для полёта на Международную космическую станцию на корабле Crew Dragon компании SpaceX Илона Маска выбраны, их объявят через месяц, сообщил телеканал CNBC со ссылкой на исполнительного директора фирмы Axiom Space Майкла Саффредини.
В марте Axiom Space заказала у компании SpaceX полёт Crew Dragon на МКС с экипажем в составе профессионального командира и трех туристов во второй половине 2021 года.
Как сообщил Саффредини телеканалу CNBC, три туриста для полёта на МКС, планирующегося в октябре 2021 года, уже определены и будут объявлены примерно через месяц.
По его словам, компания ведёт переговоры с потенциальными туристами для последующих двух полётов, которые будут осуществляться раз в полгода.
В январе Axiom Space сообщила, что планирует создать четыре коммерческих модуля (узловой, исследовательско-производственный, жилой и обзорный) для МКС с запуском первого из них в 2024 году. В будущем после принятия решения о завершении эксплуатации МКС эти модули будут отстыкованы от станции и образуют отдельную коммерческую станцию. Для этого ее дооснастят большой энергетической платформой.
Компания Axiom Space основана в 2016 году бывшим руководителем программы МКС в НАСА Майклом Саффредини.
В 2001-2009 годах на российских кораблях "Союзах" по контрактам с американской компанией Space Adventures на МКС были доставлены семь туристов, в том числе дважды - американец Чарльз Симони.

Обломки взорвавшегося бака "Фрегата" не угрожают МКС и спутникам
16:16 05.06.2020

МОСКВА, 5 июн - РИА Новости. Обломки бака разгонного блока "Фрегат", взорвавшегося в космосе в мае, не угрожают Международной космический станции и российским спутникам, сообщил РИА Новости представитель пресс-службы "Роскосмоса".

Ранее 18-я эскадрилья контроля космического пространства ВВС США сообщила, что бак "Фрегата" взорвался на орбите 8 мая с образованием 65 обломков. Позже в пресс-службе "Роскосмоса" РИА Новости подтвердили разрушение бака и сообщили, что головной научный институт госкорпорации - ЦНИИмаш - уточняет количество и параметры орбит обломков.

В пятницу из данных, размещенных на специализированном сайте ВВС США space-track.org, следовало, что обломки бака "Фрегата" разлетелись на тысячи километров.

"В настоящее время опасных сближений российской орбитальной группировки, в том числе и МКС, с фрагментами разрушения сбрасываемого блока баков разгонного блока "Фрегат-СБ" не выявлено", - сказал представитель пресс-службы "Роскосмоса".

Он отметил, что расчеты проводятся специалистами российской автоматизированной системы предупреждения об опасных сближениях в околоземном космическом пространстве два раза в сутки.

Взорвавшийся объект представлял собой тороидальный сбрасываемый блок баков разгонного блока "Фрегат-СБ", который при выведении спутника на орбиту отделился после израсходования топлива. Разрушившийся блок баков использовался в июле 2011 года для доставки в космос обсерватории "Спектр-Р".

Спойлер

В апреле 2019 года представитель ЦНИИмаша Юрий Колюка сообщил, что около 250 разрушений космических объектов (действующие и недействующие спутники, отработавшие ступени ракет-носителей и разгонные блоки) зафиксировано на орбите с 1961 года, когда произошло первое подобное событие. По его словам, разрушения космических объектов происходили либо в результате их взрывов, либо после столкновения с другими объектами.

Today, it is a mainstay in a diversity of fields, such as metal cutting tools, armor piercing projectiles, automotive engine connecting rods, and self-lubricating bearings. Future applications include use of liquid phase sintering as a means to perform in-space fabrication and repair, and for example using lunar regolith to fabricate structures on the moon or using metal powder to fabricate replacement components during extraterrestrial exploration. The MSL SCA-GEDS-German (NASA Sample Cartridge Assembly-Gravitational Effects on Distortion in Sintering) experiment focuses on determining the underlying scientific principles to forecast density, size, shape, and properties for liquid phase sintered bodies over a broad range of compositions in Earth-gravity (1g) and microgravity (μg) conditions.

Radiation Dosimetry Inside ISS-Neutrons (RADI-N2):

Спойлер

The crew retrieved eight dosimeters from the NOD1O3 Rack Front panel area and handed them over to the Russian crew for processing. 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.

ISS Crew Handover:

Спойлер

The 62S crew continued handover to the Demo-2 crew including on-orbit practices and lessons learned related to ISS systems and payloads. They also reviewed topics that are not limited to a particular module or scheduled activity as well as those that are usually scheduled as separate activities. This will allow the crew to be on the same page regarding various onboard techniques.

Treadmill (T2) Troubleshooting:

Спойлер

During the weekly power cycle of the T2 treadmill on GMT 156, the command to shut down the Command Logic Unit (CLU) failed which prevented the power cycle of the T2 rack. Ground teams attempted several troubleshooting steps yesterday to recover the T2 rack without success and believed the issue was due to a corrupted SD Card. Today, the crew attempted to recover the SD card but were unsuccessful. Discussions are ongoing to determine future recovery steps and T2 is currently declared non-operational.

Quick Response Crew Trainer (QRCT) On Board Training (OBT):

Спойлер

Today the crew utilized a newly developed tool for a training session. The QRCT OBT is training for USOS failures that require crew to perform onboard hardware manipulation and vehicle commanding to protect crew/vehicle safety. In the event of a USOS failure that would impact crew/vehicle safety the prime USOS crew would execute this Quick Response to protect the vehicle from failures that may cause loss of ground communication. Today's OBT session was the beta test run of the QRCT as an onboard trainer.
