Veteran Astronauts Conclude Spacewalk for Thermal Maintenance

Mark Garcia
Posted May 16, 2018 at 2:26 pm


The Earth passes 250 miles below spacewalker Ricky Arnold today while he is attached to the tip of the Canadarm2 robotic arm in the middle of swapping television camera gear.

Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA completed the fifth spacewalk of this year at 2:10 p.m. EDT, lasting 6 hours, 31 minutes. The two astronauts moved the Pump Flow Control Subassembly (PFCS) from a spare parts platform on the station's truss to the Dextre robotic arm. The PFCS drives and controls the flow of ammonia through the exterior portions of the station's cooling system. The team then removed and replaced a camera group and a degraded Space to Ground Transmitter Receiver Controller, and was also able to complete several get-ahead tasks.

Spacewalkers have now spent a total of 54 days, 16 hours and 40 minutes working outside the station in support of assembly and maintenance of the orbiting laboratory.

Tiny Satellite's First Global Map of Ice Clouds

Looking at Earth from the International Space Station, astronauts see big, white clouds spreading across the planet. They cannot distinguish a gray rain cloud from a puffy white cloud. While satellites can see through many clouds and estimate the liquid precipitation they hold, they can't see the smaller ice particles that create enormous rain clouds.

Although it was only designed to last three months, the tiny CubeSat known as IceCube has been orbiting Earth for a full year, collecting data on a hard-to-study type of cloud. In that time, IceCube has created a global map of these ice clouds around the planet, which could someday help improve models and forecasts.

An experimental small satellite has filled this void and captured the first global picture of the small frozen particles inside clouds, normally called ice clouds.

Deployed from the space station in May 2017, IceCube is testing instruments for their ability to make space-based measurements of the small, frozen crystals that make up ice clouds. "Heavy downpours originate from ice clouds," said Dong Wu, IceCube principal investigator at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Ice clouds start as tiny particles high in the atmosphere. Absorbing moisture, the ice crystals grow and become heavier, causing them to fall to lower altitudes. Eventually, the particles get so heavy, they fall and melt to form rain drops. The ice crystals may also just stay in the air.

Like other clouds, ice clouds affect Earth's energy budget by either reflecting or absorbing the Sun's energy and by affecting the emission of heat from Earth into space. Thus, ice clouds are key variables in weather and climate models.

This is a three-month average of ice clouds. The brightest peak areas represent the largest concentration of ice clouds. They are also the spots with heavy precipitation beneath. They reach up to the top of the troposphere from deep convection, which is normally strongest in the //tropics.

Measuring atmospheric ice on a global scale remains highly uncertain because satellites have been unable to detect the amount of small ice particles inside the clouds, as these particles are too opaque for infrared and visible sensors to penetrate. To overcome that limitation, IceCube was outfitted with a submillimeter radiometer that bridges the missing sensitivity between infrared and microwave wavelengths.

Despite weighing only 10 pounds and being about size of a loaf of bread, IceCube is a bona fide spacecraft, complete with three-axis attitude control, deployable solar arrays and a deployable UHF communications antenna. The CubeSat spins around its axis, like a plate spinning on a pole. It points at Earth to take a measurement then looks at the cold space to calibrate.

Originally a 30-day technology-demonstration mission, IceCube is still fully operational in low-Earth orbit almost a year later, measuring ice clouds and providing data that's "good enough to do some real science," Wu said.

"The hard part about developing the CubeSat is making the commercial parts durable in space," said Tom Johnson, Goddard's Small Satellite manager stationed at NASA's Wallops Flight Facility in Virginia. "We bought commercial components for IceCube and spent a lot of time testing the components making sure each part worked."

Over the past year, engineers tested the satellite's limits while on orbit. They wanted to see if the instrument's batteries stored enough power to run 24 hours. IceCube charges its batteries when the Sun shines on its solar arrays. During the test, safeguards prevented the satellite from losing all its power and ending the mission; however, the test was successful. The batteries operated the IceCube all night and recharged during the day. This change made the CubeSat more valuable for science data collection.

While the IceCube team planned for the mission to operate for 30 days in space, "It does not cost very much to keep it going," Johnson said, "so we extended the mission due to the outstanding science that IceCube is performing. We download data eight to 10 times a week. Even if we miss a week, the CubeSat can hold a couple of weeks of data."

Johnson says he is not surprised by how long IceCube has lasted. "It will last about a year, when it will reenter Earth's atmosphere and burn up in."

The IceCube team built the spacecraft using funding from NASA's Earth Science Technology Office's (ESTO) In-Space Validation of Earth Science Technologies (InVEST) program and NASA's Science Mission Directorate CubeSat Initiative.

Small satellites, including CubeSats, are playing an increasingly larger role in exploration, technology demonstration, scientific research and educational investigations at NASA. They have been used in planetary space exploration, fundamental Earth and space science, and developing precursor science instruments like cutting-edge laser communications, satellite-to-satellite communications and autonomous movement capabilities.

This morning the crew deactivated the TPF experiment equipment in the Multi-Purpose Small Payload Rack (MSPR) for the experiment run completed overnight. The Two-Phase Flow experiment investigates the heat transfer characteristics of flow boiling in the microgravity environment. This experiment provides a fundamental understanding of the behaviors of bubble formation, liquid-vapor flow in a tube, and how heat transfers in cooling systems. Two-phase flow employs a sample cooling loop using perfluorohexane, often used in coolants for electronics, to establish flow rate and heating power in different conditions.

This project is the second of a two-part experiment that seeks to evaluate the involuntary cell contractions of aortic smooth muscle cells in a microgravity environment. This research could lead to a better understanding of the contractile mechanism that operates within these cells to control blood pressure, which could ultimately lead to novel treatments for high blood pressure.

Spire (San Francisco, CA)

Tracking of oceangoing ships is of limited use. Information is gathered and delivered infrequently to those who need it, making it useful almost exclusively for historical understanding. Thus, it loses its value "in the moment" for real applications for both the public and private sectors, which is problematic given that 90% of global trade transits over the ocean. Spire's many small satellites provide close-to-real-time information from anywhere on Earth. In the maritime sector, these satellites increase safety and security across the planet's oceans (for example, search and rescue, piracy prevention, etc.). With results from this research, Spire will begin deployment of its full constellation of satellites to deliver near-real-time updates on maritime and weather data from anywhere on Earth.

The Continuous Liquid-Liquid Separation in Microgravity investigation will use a unique liquid separation system for liquid-liquid extraction. Unlike common separation methods, which rely on liquid sedimentation, the Zaiput Liquid-Liquid Separation system relies on surface forces to accomplish liquid-liquid extraction. Separation based on surface tension is thought to be a method independent of gravity; however, it has never been tested, and the physics of the process remain somewhat unclear. Exploring microgravity's effects on the process could improve understanding of the physics involved. Results fr om this investigation could allow Zaiput to further develop their system and potentially scale up the system to achieve flow rates suitable for chemical production.
