Astronauts Ready for Final Spacewalk
Mon, 27 Jul 2009 02:44:41 -0500

The crew of space shuttle Endeavour was awakened by the song “On the Sunny Side of the Street,” performed by Steve Tyrell and played especially for Commander Mark Polansky.

Spacewalkers Tom Marshburn and Chris Cassidy head outside to begin STS-127’s final spacewalk at 8:28 a.m. EDT. They first will secure multi-layer insulation around the Special Purpose Dexterous Manipulator known as DEXTRE. On the Zenith 1 patch panel, they will split out power channels for two of the four space station Control Moment Gyroscopes, which provide non-propulsive attitude control for the station. Currently two of the gyros are fed from the same power channel, and this activity will prevent a failure on one channel from disabling both of the gyros. Next, Marshburn and Cassidy will install video cameras on the front and back of the new Japanese Exposed Facility. And their final task will be to deploy a Payload Attach System on the Starboard 3 truss that will provide storage capability for spare space station hardware. The spacewalk is planned to last no more than six hours, 30 minutes.

MEMRISTOR INVENTED "FINALLY"- THE NEW ANALOG REVOLUTION

MEMRISTOR

A memristor /ˈmemrɪstər/ ("memory resistor") is any of various kinds of passive two-terminal circuit elements that maintain a functional relationship between the time integrals of current and voltage. This function, called memristance, is similar to variable resistance. Specifically engineered memristors provide controllable resistance, but such devices are not commercially available. Other devices like batteries and varistors have memristance, but it does not normally dominate their behavior. The definition of the memristor is based solely on fundamental circuit variables, similarly to the resistor, capacitor, and inductor. Unlike those three elements, which are allowed in linear time-invariant or LTI system theory, memristors are nonlinear and may be described by any of a variety of time-varying functions of net charge. There is no such thing as a generic memristor. Instead, each device implements a particular function, wherein either the integral of voltage determines the integral of current, or vice versa. A linear time-invariant memristor is simply a conventional resistor.

Memristor theory was formulated and named by Leon Chua in a 1971 paper. Chua extrapolated the conceptual symmetry between the resistor, inductor, and capacitor, and inferred that the memristor is a similarly fundamental device. Other scientists had already used fixed nonlinear flux-charge relationships, but Chua's theory introduces generality.

On April 30, 2008 a team at HP Labs announced the development of a switching memristor. Based on a thin film of titanium dioxide, it has a regime of operation with an approximately linear charge-resistance relationship. These devices are being developed for application in nanoelectronic memories, computer logic, and neuromorphic computer architectures.

Fourth Spacewalk Begins at 9:54 a.m. EDT
Fri, 24 Jul 2009 08:59:05 -0500

Spacewalkers Chris Cassidy and Tom Marshburn began the STS-127 mission’s fourth spacewalk at 9:54 a.m. EDT when they switched their spacesuits to battery power.

They will replace four of the remaining Port 6 truss batteries in a planned seven and a half hour spacewalk. Two of the six original P6 batteries were changed out during the mission’s third spacewalk on Wednesday before work was cut short because of anomalous carbon dioxide levels in Cassidy’s suit. The lithium hydroxide canister that scrubs CO2 from the suit was replaced for today’s spacewalk.

The new batteries are stored on the Integrated Cargo Carrier – Vertical Light Deployable, or ICC-VLD positioned near the Port 6 truss. Cassidy and Marshburn will work together to remove insulation from the old Port 6 batteries, install scoops to gently remove them, pass the batteries back and forth to a stowage location on the ICC-VLD, and repeat the process to replace them with the new batteries.

Each new battery assembly consists of 38 lightweight Nickel Hydrogen cells and associated electrical and mechanical equipment. Two battery assemblies connected in series are capable of storing a total of 8 kW of electrical power. This power is fed to the space station via the Battery Charge/Discharge Unit and Direct Current Switching Unit respectively. The batteries have a design life of 6.5 years and can exceed 38,000 charge/discharge cycles at 35% depth of discharge. Each battery measures 40” by 36” by 18” and weighs 375 pounds.

NEW JUPITER COLLISION DEDUCTED

Hubble Space Telescope Captures Rare Jupiter Collision
07.24.09
Jupiter
This Hubble picture, taken on July 23, by the new Wide Field Camera 3, is the sharpest visible-light picture taken of the atmospheric debris from a comet or asteroid that collided with Jupiter on July 19. This is Hubble's first science observation following its repair and upgrade in May. The size of the impactor is estimated to be as large as several football fields.

NASA's Hubble Space Telescope has taken the sharpest visible-light picture yet of atmospheric debris from an object that collided with Jupiter on July 19. NASA scientists decided to interrupt the recently refurbished observatory's checkout and calibration to take the image of a new, expanding spot on the giant planet on July 23.

Discovered by Australian amateur astronomer Anthony Wesley, the spot was created when a small comet or asteroid plunged into Jupiter's atmosphere and disintegrated. The only other time such a feature has been seen on Jupiter was 15 years ago after the collision of fragments from comet Shoemaker-Levy 9.

"Because we believe this magnitude of impact is rare, we are very fortunate to see it with Hubble," said Amy Simon-Miller of NASA's Goddard Space Flight Center in Greenbelt, Md. "Details seen in the Hubble view shows a lumpiness to the debris plume caused by turbulence in Jupiter's atmosphere."

The new Hubble images also confirm that a May servicing visit by space shuttle astronauts was a big success.

"This image of the impact on Jupiter is fantastic," said U.S. Sen. Barbara A. Mikulski, D-Md., chairwoman of the Commerce, Justice and Science Appropriations Subcommittee. "It tells us that our astronauts and the ground crew at the Goddard Space Flight Center successfully repaired the Hubble telescope. I'm so proud of them and I can't wait to see what's next from Hubble."

For the past several days, Earth-based telescopes have been trained on Jupiter. To capture the unfolding drama 360 million miles away, Matt Mountain, director of the Space Telescope Science Institute in Baltimore, gave observation time to a team of astronomers led by Heidi Hammel of the Space Science Institute in Boulder, Colo.

"Hubble's truly exquisite imaging capability has revealed an astonishing wealth of detail in the impact site," Hammel said. "By combining these images with our ground-based data at other wavelengths, our Hubble data will allow a comprehensive understanding of exactly what is happening to the impact debris."

Simon-Miller estimated the diameter of the impacting object was the size of several football fields. The force of the explosion on Jupiter was thousands of times more powerful than the suspected comet or asteroid that exploded over the Siberian Tunguska River Valley in June 1908.

The image was taken with the Wide Field Camera 3. The new camera, installed by the astronauts aboard space shuttle Atlantis in May, is not yet fully calibrated. While it is possible to obtain celestial images, the camera's full power has yet to be seen.

"This is just one example of what Hubble's new, state-of-the-art camera can do, thanks to the STS-125 astronauts and the entire Hubble team," said Ed Weiler, associate administrator of NASA's Science Mission Directorate in Washington. "However, the best is yet to come."

Kibo Robotics Work Planned Today

The combined STS-127 and Expedition 20 crew was awakened at 5:33 a.m. EDT with the song “Tiny Dancer,” performed by Elton John. The song was selected for Endeavour Commander Mark Polansky.

At 9 a.m. EDT NASA Television will air a news conference introducing the crew of Expedition 21, astronaut Jeff Williams, Russian cosmonaut Maxim Suraev and spaceflight participant Guy Lalibert� of Canada.

The Kibo robotic arm will be used for the first time operationally to move space station hardware. Koichi Wakata and Tim Kopra will transfer two experiments and a communication system from the Japanese Exposed Section to the Japanese Exposed Facility. The Inter-orbit Communication System (ICS) is the Kibo-specific communications system for uplinking and downlinking data, images and voice between Kibo and the Mission Control Center at Tsukuba Space Center by way of Japan’s own relay satellite, the Data Relay Test Satellite, or DRTS. The two experiments are Monitor of All-sky X-ray Image (MAXI) and Space Environment Data Acquisition equipment – Attached Payload (SEDA-AP).

Kibo Japanese Experiment Module
The Japanese Experiment Module, or JEM, called Kibo -- which means "hope" in Japanese -- is Japan's first human space facility and enhances the unique research capabilities of the International Space Station.

09140005 -- KiboExperiments in Kibo focus on space medicine, biology, Earth observations, material production, biotechnology and communications research. Kibo experiments and systems are operated from the Mission Control Room at the Space Station Operations Facility, or SSOF, at Tsukuba Space Center in Ibaraki Prefecture, Japan, just north of Tokyo.

Image to right: Kibo's Pressurized Module, shown here at its manufacturing facility in Nagoya, Japan, is 11.2 meters (36.7 feet) long. Photo courtesy of JAXA.

Kibo consists of six components: two research facilities -- the Pressurized Module and Exposed Facility; a Logistics Module attached to each of them; a Remote Manipulator System; and an Inter-Orbit Communication System unit. Kibo also has a scientific airlock through which experiments are transferred and exposed to the external environment of space. The various components of JEM will be assembled in space over the course of three Space Shuttle missions. The missions are designated assembly flights 1J, 1J/A and 2J/A.

Pressurized Module

09140003 -- Kibo Pressurized ModuleThe Pressurized Module, or PM, provides a shirt-sleeve environment in which astronauts conduct microgravity experiments. There are a total of 23 racks, including 10 experiment racks, inside the PM providing a power supply, communications, air conditioning, hardware cooling, water control and experiment support functions.

Image to left: Kibo's Pressurized Module. Photo courtesy of JAXA.

The PM is 11.2 meters (36.7 feet) long and 4.4 meters (14.4 feet) in diameter, about the size of a large tour bus.

Exposed Facility

The Exposed Facility, or EF, is a unique platform on the ISS that is located outside of the Pressurized Module and is continuously exposed to the space environment. Astronauts exchange experiment payloads or hardware from the Pressurized Module through the scientific airlock using the Kibo Remote Manipulator System. Items positioned on the exterior platform focus on Earth observation as well as communication, scientific, engineering and materials science experiments.

The EF is a platform that can hold up to 10 experiment payloads at a time and measures 5.6 meters (18.4 feet) wide, 5 meters (16.4 feet) high and 4 meters (13.1 feet) long.

Experiment Logistics Modules (Pressurized and Exposed Sections)

The Experiment Logistics Modules, or ELMs, serve as on-orbit storage areas that house materials for experiments, maintenance tools and supplies. The Pressurized Module and the Exposed Facility each have an ELM.

Pressurized Section:The Experiment Logistics Module - Pressurized Section, or ELM-PS, is a short cylinder attached to the top of the Pressurized Module that can hold eight experiment racks. It measures 4.4 meters (14.4 feet) in diameter and 3.9 meters (12.8 feet) long.

Exposed Section: The Experiment Logistics Module - Exposed Section, or ELM-ES, is a pallet that can hold three experiment payloads. It measures 4.9 meters (16.1 feet) wide, 2.2 meters (7.2 feet) high and 4.2 meters (13.8 feet) long.

Remote Manipulator System

STS085-E-5030 -- Small Fine Arm PrototypeThe Remote Manipulator System, or RMS, consists of two robotic arms that support operations on the outside of Kibo. The Main Arm can handle up to 6.4 metric tons (14,000 pounds) of hardware and the Small Fine Arm, when attached to the Main Arm, handles more delicate operations. Each arm has six joints that mimic the movements of a human arm.

Image to right: A prototype for the Small Fine Arm was tested during a Space Shuttle mission in 1997.

Astronauts operate the robot arms from a remote computer console inside the Pressurized Module and watch external images from a camera attached to the Main Arm on a television monitor at the RMS console. The arms are specifically used to exchange experiment payloads or hardware located on the Exposed Facility and Experiment Logistics Module - Exposed Section and from inside the Pressurized Module through a scientific airlock, support maintenance tasks of Kibo and handle orbital replacement units.

The operations of a prototype Small Fine Arm were evaluated as part of the Manipulator Flight Demonstration experiment conducted during the STS-85 Space Shuttle mission in 1997.

The Main Arm measures 9.9 meters (32.5 feet) long, and the Small Fine Arm measures 1.9 meters (6.2 feet).

Inter-Orbit Communication System

The Inter-Orbit Communication System, or ICS, allows the operators in the Mission Control Room at the SSOF at Tsukuba Space Center to send commands to Kibo and receive system, payload and video data from Kibo for scientific payload operations. The Mission Control Room uses the Tracking and Data Relay Satellite System, or TDRSS, to communicate with the ICS. An external ICS unit handles communications with TDRSS, while an internal ICS unit located in the Pressurized Module handles data exchange throughout the Kibo facilities.

Mission Control Room

The Mission Control Room, or MCR, is the hub of round-the-clock, real-time operations of Kibo. Ongoing control of Kibo systems such as the electric power distribution system and the thermal control system, monitoring the condition of Japanese experiment equipment, sending control commands, and real-time operations planning is conducted here. A flight director oversees all operations in the MCR.


Communication with other control centers and the Space Station crew occur in the MCR. Flight controllers in Japan work in cooperation with controllers at NASA's Mission Control Center in Houston, Texas, the Russian Mission Control Center near Moscow and the Payload Operations Center, Huntsville, Ala.

Experiment status and measurement data are distributed to users from the MCR. Researchers and those in charge of experiment operations are located in a User Operations Area at the SSOF, where they monitor, control and analyze experiment data, as well as support and carry out on-orbit experiments from the ground

NASA STUDENTS PROGRAM
NASA Student Airborne Research Program Takes Flight
EDWARDS, Calif. -- Twenty-nine undergraduate and graduate students are participating in a six-week NASA Airborne Science field experience designed to immerse them in NASA's Earth Science research. The students represent 26 colleges and universities across the U.S. and nine foreign countries.

NASA's Student Airborne Research program runs from July 6 to Aug. 14 in California. The program began with lectures from university faculty members, research institutions and NASA scientists at the University of California, Irvine. One of the speakers is Sherwood Rowland of the University of California, Irvine, a Nobel Laureate in chemistry, who is a long-time user of NASA's DC-8 airborne capabilities for his research on atmospheric chemistry.

Using the DC-8 flying laboratory based at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif., the students will get a rare behind-the-scenes look at instrument integration, flight planning and payload testing that is the basis of every successful Earth Science airborne campaign carried out by NASA. These airborne research campaigns play a pivotal role in the calibration and validation of NASA's space-borne Earth observations, remote sensing measurements and the high-resolution imagery for Earth system science.

Divided into the investigative groups of atmospheric science, algal blooms and crop classification, students will have the opportunity to fly aboard one of two six-hour DC-8 flights departing from NASA's Palmdale facility. The aircraft will travel north over the San Joaquin Valley for an air-quality investigation, over the Sacramento-San Joaquin River Delta to observe vegetation, and south over Monterey Bay to research algae blooms.

The student program is one of NASA's tools for training future scientists for Earth Science missions that can assist with studies and the development and testing of new instruments and future satellite mission concepts. The program's goal is to stimulate interest in NASA's Earth Science research and aid in recruitment of the next generation of engineers and scientists. Through this and the agency's other college and university programs, NASA is developing critical skills and capabilities needed for the agency's engineering, scientific and technical missions.

The Student Airborne Research Program is managed through the National Suborbital Education and Research Center at the University of North Dakota, with funding and support from NASA's Airborne Science Program. The center was established through a cooperative agreement between the University of North Dakota and NASA.

CHANDRAYAAN SENSOR FAILURE

“Chandrayaan’s first sensor failed much earlier”
The remainder of the two-year mission will be completed using a gyroscope
— Photo: ISRO

Part of RICCO Crater (North Polar Region of the Moon) as viewed by Chandrayaan’s Terrain Mapping Camera after the orbit was raised to 200 km.

BANGALORE: Even as the failure of Chandrayaan’s ‘star sensor’ continues to make news, top officials at the Indian Space Research Organisation (ISRO) have revealed that the April 26 snag, announced on Friday, was the second sensor failure — the first one having occurred “much earlier.”

The lunar spacecraft had on board two star sensors, with one as back-up, to determine the orientation or “attitude” while in orbit. Although the ISRO maintained that the “spacecraft started malfunctioning on April 26,” necessitating a switch-over to a contingency gyroscope, it appears that the malfunction had taken place earlier.

At a press conference on Friday, ISRO chief Madhavan Nair said the star sensor failure was due to “excessive radiation from the sun.” It was detected on May 16. As the sensor could not be recovered at this stage, the remainder of the two-year mission would be completed using a gyroscope, an electro-mechanical device that was used in Indian Remote Sensing satellites.

Gyroscopes, however, needed regular intervention to stabilise their orientation, and the ISRO’s ground stations had begun weekly attitude corrections, the official said. With the failure of the two star sensors, the number of technical glitches Chandrayaan has encountered in its eight-month lunar orbit stands at three — the third being the failure of a Bus Management Unit, which has been replaced with a back-up unit.

The public relations office at the ISRO did not confirm that the April 26 sensor snag was the second of its kind.

Thermal heating

The Rs.400-crore satellite encountered problems of thermal heating also. In one instance in January, the temperature within the spacecraft rose to 80 degrees Celsius, according to another ISRO official. The optimal temperature for electronic packages and payloads is zero to 40 degrees.

Chandrayaan was launched on October 22 carrying 11 payloads (scientific experiments), including the moon impact probe that crash-landed on a designated location near the moon’s South Pole in November.

Five payloads were developed by international space agencies, including the National Aeronautics and Space Administration (NASA) and the European Space Agency.

International Space Station flight controllers have set aside about 2.5 hours this morning to replace components of the toilet in the U.S. Destiny lab, the Waste and Hygiene Compartment (WHC). Sunday, the system’s dose pump failed and most likely contaminated internal parts when about six liters of pre-treated water flooded the separator pump. The pump introduces the correct amount of chemicals into the system to help separate liquids from solid waste.

Space station Commander Gennady Padalka and Flight Engineer Frank De Winne donned protective gear to install the replacement parts.

This is one of three toilets available to the 13-member crew, which has been using a similar toilet in the Russian Zvezda module and Endeavour’s toilet, the Waste Collection System, or WCS. The temporary shutdown of the Destiny toilet has no significant impact on joint docked operations.

STS-127 lead spacewalker Dave Wolf and Endeavour Mission Specialist Tom Marshburn began the mission’s second spacewalk at 11:27 a.m. EDT, when they switched their spacesuits to battery power. The space walk is expected to last 6.5 hours.

The pair will retrieve three hardware spares from the Integrated Cargo Carrier – Vertical Light Deployable, or ICC-VLD, and place them in a long-term storage location on the outside of the station’s Port 3 truss. On Sunday, robotic arm operators moved the cargo carrier to a location where Wolf and Marshburn can easily access it.

First, Wolf and Marshburn will retrieve a Ku-Band Space-to-Ground Antenna from the ICC-VLD and place it in the Port 3 External Stowage Platform, ESP-3. Next, they will transfer a Pump Module that is part of the station’s exterior thermal control system, and a Linear Drive Unit that helps the mobile transporter move along the truss backbone, to ESP-3. Marshburn will take a fixed grapple bar and preposition it on an ammonia tank assembly in preparation for its replacement on STS-128 in August. Finally, both spacewalkers will move a television camera that was launched on the Japanese Exposed Facility (JEF) to its final location on JEF. The spacewalkers will be assisted by Julie Payette and Doug Hurley, who will help move Wolf from the ICC-VLD to the ESP-3 on the space station robotic arm.

Spacewalkers Dave Wolf and Tom Marshburn wrapped up a six hour, 53 minute spacewalk at 6:20 p.m. EDT.

Wolf and Marshburn completed most of their planned tasks, deferring a video camera setup to a future spacewalk. Wolf removed three hardware spares – a Ku-Band Space-to-Ground Antenna, a Pump Module and a Linear Drive Unit, from the Integrated Cargo Carrier – Vertical Light Deployable (ICC-VLD). With each spare in hand, Wolf rode the space station robotic arm from the ICC to the Port 3 external stowage platform (ESP-3), where he and Marshburn attached them for long-term storage. Julie Payette and Doug Hurley operated the robotic arm. Marshburn mounted a grapple bar onto an ammonia tank assembly so that the STS-128 space shuttle mission in August can move the tank by robotic arm. Marshburn also attached two insulation sleeves for the Station to Shuttle Power Transfer System.

This was the second of five STS-127 spacewalks, the 127th in support of International Space Station assembly and maintenance, totaling 792 hours, 31 minutes. It was the 215th American spacewalk in history. It was Wolf’s sixth spacewalk, totaling 38 hours, 44 minutes and placing him 19th on the all-time list. It was Marshburn’s first excursion.

At 11:06 a.m. EDT Endeavour Pilot Doug Hurley and Mission Specialist Koichi Wakata used the space station's robotic arm to grab the Japanese Exposed Facility (JEF), nestled in the shuttle payload bay. They will lift it out of the bay at 1:43 p.m., hand it to the shuttle robotic arm at 2:43 p.m., and move the station's arm into position for installation at 3:53 p.m. The shuttle arm will hand the Exposed Facility back to the station arm at 5:23 p.m., and finally the station arm will move the JEF into position for installation to the Kibo laboratory at 5:38 p.m.

Wolf and Kopra's spacewalk is scheduled to start at 11:58 a.m. They will remove insulation from Kibo's berthing mechanism, disconnect power cables providing electricity to the shuttle's Integrated Cargo Carrier, use a specially designed tool to release the station's Earth-facing Unpressurized Cargo Carrier Attachment System, secure covers on the Harmony and Unity modules' common berthing mechanisms, and set up a payload attach system on the station's backbone. Mission Specialists Chris Cassidy and Tom Marshburn will help coordinate the spacewalk from inside.

STS-127 Commander Mark Polansky will help out with the Exposed Facility's arm-to-arm handoffs and work with cargo, water and nitrogen transfers, and Mission Specialist Julie Payette will assist with robotic and camera operations.

Crew Inspects Shuttle, Prepares for Docking

Astronauts aboard Space Shuttle Endeavour spent their first full day in space conducting a routine inspection of their thermal protection system ahead of docking Friday.

While inspections take place to ensure Endeavour’s wing leading edge panels and nosecap are in good shape, imagery experts will continue to assess the overall health of the shuttle’s thermal protection system. The early review indicates only a few minor dings in some tiles is present in video due to some unexpected losses of small foam pieces from the external tank.

Endeavour’s crew also checked out spacesuits that will be used during the five spacewalks planned during the docked phase of the mission. In preparation for docking, the crew tested rendezvous equipment, installed an orbiter docking system “centerline” camera and extended the docking ring atop the docking system before heading for its eight hour sleep period beginning about 9 p.m. EDT.
