Living and Working in Space: Radiation

NASA

Опубликовано: 15 апр. 2019 г.

Living and working in space requires human perseverance. Future missions will focus on exploration at greater distances from Earth; to the Moon and then to Mars. These missions will mean humans will stay in space for extended durations. To ensure that these goals are achieved, NASA's astronauts must be able to perform at peak productivity under even the most daunting conditions.
Our research and science enables human spaceflight exploration to expand the frontiers of knowledge, capability, and opportunity in space.

Космонавты Роскосмоса Олег Кононенко и Алексей Овчинин установили в модуле «Рассвет» аппаратуру для проведения нового биологического эксперимента «Ряска». 

Объектом для исследования стала болотная трава, которая плавает на поверхности воды. Его цель — демонстрация механизмов ориентации в невесомости фоточувствительных органов высших растений на водную и воздушную фазы их среды обитания. 

Новизна заключается в том, что параллельно исследованию в космосе, учащиеся школ, под руководством сотрудников ИМБП РАН, проводят точно такой же эксперимент и на Земле. Результаты предполагается использовать в учебном процессе и подготовке образовательного материала, демонстрирующего выявление особенностей развития растений в условиях микрогравитации.

На борту МКС для реализации исследования используется устройство «Фаза» с тремя сосудами, в которых содержится вода, воздух и ряска. Для имитации солнечных лучей была установлена светодиодная система локального освещения.

The Northrop Grumman Antares rocket carrying a Cygnus resupply spacecraft is seen during sunrise on Pad-0A, Tuesday, April 16, 2019 at NASA's Wallops Flight Facility in Virginia

The U.S. Cygnus resupply ship from Northrop Grumman is encapsulated atop the Antares rocket and standing at its launch pad in Virginia. The Expedition 59 crew is training for its capture at the end of the week in the midst of ongoing life science aboard the International Space Station.

Cygnus will blast off Wednesday at 4:46 p.m. EDT from NASA's Wallops Flight Facility. It will deliver about 7,600 pounds of science, supplies and hardware to the orbital residents. Flight Engineer Anne McClain, with astronaut David Saint-Jacques backing her up, will command the Canadarm2 robotic arm to reach out and capture Cygnus Friday about 5:30 a.m.

The duo continued sharpening their robotics skills today as they practiced Friday's Cygnus capture maneuvers and techniques on a computer. NASA TV will broadcast the space freighter's launch and capture activities live.

McClain started the day setting up a mouse habitat that will house rodents to gain insight into the immune system's response to long-term spaceflight. Saint-Jacques set up the 360° camera in Tranquility module for more virtual reality filming of crew life on the station.

Flight Engineer Christina Koch started Tuesday collecting and spinning her blood samples in a centrifuge for the Myotones muscle study. She then joined NASA astronaut Nick Hague for body measurements and ultrasound scans to research how microgravity impacts the biochemical properties of muscles.

ISS Daily Summary Report – 4/15/2019

Sally Ride Earth Knowledge Acquired by Middle Schools (EarthKAM):

Спойлер

Today EarthKAM mission 66 concluded with a shutdown and stow of the related hardware. As of the latest report, a total of 225 schools representing 24,512 students and 31 countries had signed up to request images; 22,123 image requests had been submitted, 10,278 images had been downlinked, and 9,982 images had been posted to the web (earthkam.org). A total of 5 Russian schools representing 64 students participated in this mission. EarthKAM allows thousands of students to photograph and examine Earth fr om a space crew's perspective. Using the Internet, the students control a special digital camera mounted on-board the ISS. This enables them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest fr om the unique vantage point of space. The EarthKAM team then posts these photographs on the Internet for viewing by the public and participating classrooms around the world.

Fluids Integrated Rack (FIR)/Light Microscopy Module (LMM)/Biophysics-6 experiment start:

Спойлер

The crew removed a LMM/Biophysics-6 (Bio-6) plate fr om MELFI and allowed it to thaw. When the crew performed an inspection of the thawed plate, they reported a possible broken capillary. The plate was bagged and stowed appropriately and ground teams will assess a forward plan. LMM/Bio-6, more formally known as Growth Rate Dispersion as a Predictive Indicator for Biological Crystal Samples Wh ere Quality Can Be Improved with Microgravity Growth, studies ground-based predictions of which crystals benefit from crystallization in microgravity, wh ere Earth's gravity does not interfere with their formation. In this experiment, two proteins of interest in cancer treatment and radiation protection are to be studied. Observing crystallized proteins via X-ray crystallography on the ground allows scientists to determine how they are built, which can explain how they work or how other molecules, such as drugs, might interact with them.

The ISS Experience:

Спойлер

The crew set up the ISS Experience hardware with the goal of capturing the crews' evening Daily Planning Conference evening meal. These are both Human interactions targets of interest for the ISS Experience team. 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. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

SUBSA (Solidification Using a Baffle in Sealed Ampoules) Sample Exchange:

Спойлер

The crew removed the completed InI (Indium Iodide) sample cartridge #1 and ins erted sample cartridge #7 to be processed. Both of these are solidification-from-melt samples and require up to 50 hours to be fully processed. The experiment currently running in SUBSA is the Detached Melt and Vapor Growth of InI. InI is ideal for space experiments in the SUBSA Transparent Furnace because it is non-toxic, has a relatively low melting point of only 365°C, and does not react or stick to the silica crucible. Directional solidification of InI from the melt can be performed at a rate of 5 mm/hr, and growth from the vapor can be performed at ~5 mm/week. This work advances the process of fabricating high-quality InI and other crystals on Earth for use as better and less expensive detectors of nuclear radiation.

Cygnus On-board Training:

Спойлер

Crewmembers scheduled to capture NG-11 (Cygnus) performed a Robotics Onboard Trainer (ROBoT) session. ROBoT is an on-orbit version of the ground-based Dynamics Skills Trainer (DST) that simulates robotics operations with graphical feedback. NG-11 is on track to launch on April 17 and berth to ISS on April 19.

Microgravity Experiment Research Locker Incubator (MERLIN)-1 Recovery:

Спойлер

Last week the MERLIN-1 cooler used by the crew in the Galley as a refrigerator, experienced a Disk on Chip (DOC) failure. The crew was able to recover the MERLIN on Saturday by temporarily connecting it to a Space Station Computer (SSC) for a specialized ground recovery procedure. This is the first time this failure has been recovered on orbit. Previous units needed to be returned to the ground for repair.

Portable Emergency Provisions (PEPS) Inspection:

Спойлер

The crew inspected Portable Fire Extinguishers (PFEs), Extension Hose Tee Kits (EHTKs), Portable Breathing Apparatuses (PBAs) and Pre-Breathe Masks for damage. They also ensured each item was in a useable configuration and fully functional. Considered routine maintenance, this inspection is scheduled every 45 days.

[свернуть]

Mobile Servicing System (MSS) Operations:

Спойлер

On Friday, Robotics Ground Controllers powered up MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) for SPDM to grasp the Robotic Refueling Mission (RRM) 3 tool pedestal and retrieved it from the Japanese Experiment Module (JEM) Airlock (AL) after it had been extended. MSS was maneuvered over the Express Logistic Carrier (ELC) 1 wh ere the RRM3 payload is located.

Controllers commanded the SPDM to ins ert the tool pedestal in to the RRM3 interface. Once mated, the connector was extended to provide a power and date connection to the tools. Once this was confirmed, the SPDM released the tool pedestal and backed away. The MSS was then configured in preparation of a Mobile Transporter (MT) translation from worksite 7 to worksite 3.

Following translation, Controllers repowered the MSS. SSRMS stowed SPDM onto Mobile Base System (MBS) 2. After a base change, the SSRMS released the SPDM and was configured for a walkoff to Node 2 Power Data Grapple Fixture (PDGF). Upon successful base change, the SSRMS released MBS PDGF 1 and was parked in preparation for the crew offset grapples scheduled on Tuesday, April 16. Finally ROBO performed SSRMS checkouts for NG-11 capture on April 19.

Robotic "Bees" Are About to Join Astronauts in Space

There are some things only humans can do in space. The rest can be left to robots. To free up valuable time for astronauts living and working aboard the International Space Station, we're sending three robotic helpers to the orbiting outpost. Developed and built at our Ames Research Center in California's Silicon Valley, the cube-shaped Astrobee robots will each stay as busy as a bee flying around the space station and assisting crew with routine tasks like maintenance and tracking inventory. The robots will also help researchers on the ground carry out experiments, test new technologies and study human-robot interaction in space. Learning how robots can best work with humans in close proximity will be key for exploring the Moon and other destinations. Get to know more about our new robots headed to space:

The Astrobee robots were tested inside a special lab at our Ames Research Center where researchers created a mockup of the space station's interior.

Спойлер

The flying robots are propelled by fans. They can move in any direction and turn on any axis in space.

Each robot is equipped with cameras and sensors for navigating inside the space station and avoiding obstacles.

Claw power! Astrobees have a robotic arm that can be attached for handling cargo or running experiments.

Astrobee is battery powered. When its battery runs low, the robot will autonomously navigate and dock to a power station to recharge.

The robots can operate in either fully automated mode or under remote control by astronauts or researchers on Earth.

Astrobee builds on the success of SPHERES, our first-generation robotic assistant that arrived at the space station in 2006.

Two of the three Astrobee robots are scheduled to launch to space this month from our Wallops Flight Facility in Virginia! Tune in to the launch at www.nasa.gov/live.

Did you know that cargo vehicles don't autonomously dock to @Space_Station? Instead, they park close by and we capture them with #CanadaArm2 – called a "grapple." We're practicing that maneuver a lot this week to be ready for Friday's planned arrival of #Cygnus NG-11.
