A Burst of Spring
Spring has sprung on Mars, bringing with it the disappearance of carbon dioxide ice (dry ice) that covers the north polar sand dunes. In spring, the sublimation of the ice (going directly from ice to gas) causes a host of uniquely Martian phenomena. In this image streaks of dark basaltic sand have been carried from below the ice layer to form fan-shaped deposits on top of the seasonal ice. The similarity in the directions of the fans suggests that they formed at the same time, when the wind direction and speed was the same. They often form along the boundary between the dune and the surface below.

As a team was working on better ways to detect hazardous gases on the shuttle launch pad, they found out they also could build something to find hazardous gases venting from a volcano.
Tim Griffin, foreground, and designer Richard Arkin miniaturized the leak detector system used by the space shuttle and then found out it could be used for volcano studies. Working with Costa Rican officials, the mobile detector has been used to find out what gases volcanoes give off and how much. With enough information, the detectors are expected to be able to predict a volcanic eruption in time to allow safe evacuations of nearby areas.

The International Space Station Program has received the 2010 Aviation Week Space Laureate Award. This year’s winners were recognized for extraordinary accomplishments in the aerospace and defense industries. In announcing the Space Laureate award, Aviation Week noted that the space station, currently orbiting 220 miles above the Earth with a multicultural crew of three on board, is “essentially complete after 25 years of political upheavals, redesigns, technical problems and the loss of the space shuttle Columbia. “In 2009, the final major pressurized modules were attached to the orbiting laboratory, and its life support and other systems upgraded to support a full-time crew as large as six,” the announcement continued. “The five partner agencies are working to win funding to operate the station until 2020, and engineers already are recertifying its structure until 2028. It has become the model for international cooperation on future human exploration deeper into the Solar System.” Representing the five space agencies in the partnership – and the thousands of men and women who have built the space station – were partner program managers Michael Suffredini, NASA; Pierre Jean, Canadian Space Agency; Bernardo Patti, European Space Agency; Yoshiyuki Hasegawa, Japan Aerospace Exploration Agency, and Alexey Krasnov, Roscosmos. “We are honored to accept this award,” Suffredini said. “The International Space Station is an unbelievable tribute to teamwork and cooperation. We want to thank not only the space station team – including our international partners and contractors -- but also the entire shuttle and mission support teams, which are making assembly and continued operations possible.” The International Space Station is a joint project of five space agencies and 15 countries that is nearing completion and will mark the 10th anniversary of a continuous human presence in orbit later this year. The largest and most complicated spacecraft ever built, the space station is an international, technological and political achievement that represents the latest step in humankind’s quest to explore and live in space.

Credit: NASAUpon completion of assembly later this year, the station’s crew and its U.S., European, Japanese and Russian laboratory facilities will expand the pace of space-based research to unprecedented levels. Nearly 150 experiments are currently under way on the station, and more than 400 experiments have been conducted since research began nine years ago. These experiments already are leading to advances in the fight against food poisoning, new methods for delivering medicine to cancer cells and the development of more capable engines and materials for use on Earth and in space. The international partner agencies provide crew members, control centers and support teams that train and provide uninterrupted support for systems operations and coordinate the on-orbit research. The station has a mass of almost 800,000 pounds and a habitable volume of more than 12,000 cubic feet – approximately the size of a five-bedroom home, and uses state-of-the-art systems to generate solar electricity, recycle nearly 85 percent of its water and generate much of its own oxygen supply. Nearly 190 humans have visited the space station, which is now supporting its 23rd resident crew. Boeing, prime contractor, responsible for design, development, construction and integration of the ISS, recently handed over the “keys” to the station’s U.S. On-Orbit Segment to NASA at the conclusion of an Acceptance Review Board that verified the delivery, assembly, integration and activation of all hardware and software required by contract.

Commander Jeff Williams and Flight Engineers Max Suraev, Oleg Kotov, T.J. Creamer, and Soichi Noguchi are expected to snap a total of 100,000 images by the end of their mission in Earth orbit.
If a picture is worth a thousand words, then the Expedition 22 crew aboard the International Space Station is about to complete the generation of 100 million words worth of information. That’s because Commander Jeff Williams and Flight Engineers Max Suraev, Oleg Kotov, T.J. Creamer, and Soichi Noguchi are expected to snap a total of 100,000 images by the end of their mission in Earth orbit. Williams is setting a record that surpasses his own previous record of 83,856 images taken during Expedition 13 in 2006. “This week we broke my old Exp. 13 record for number of Earth photos,” Williams “tweeted” from the station. “Later, after landing and recovery, I will post some of best.” Among those digital still images is this spectacular nighttime image taken of Houston, Texas, the home of Mission Control and astronaut training, and the hub of the International Space Station Program that unites five space agencies and 15 countries in peaceful exploration and scientific research. Williams and Suraev will end their five-and-a-half-month stay on the station Thursday, when they undock their Soyuz spacecraft and head for a landing in Kazakhstan. They were part of both the Expedition 21 and 22 crews. Kotov, Creamer and Noguchi will stay on orbit, snapping more photos, for two more months before returning home after being part of both the Expedition 22 and 23 crews. All told, space station crews so far have amassed a total of almost 639,000 images. Those images include photos that document life and work aboard the space station, and photos that document the condition of the home planet from its unique perspective 220 miles above Earth. Their efforts are part of a larger collection that began with Earth observations photos during the Gemini Program of the 1960s. Many of the images are used in scientific research about the Earth, its climate, its resources and the effects humans are having on both.
The recent STS-130 space shuttle mission delivered a new observation deck known as the cupola that offers the largest window ever flown on a spacecraft, and the upcoming STS-131 shuttle mission to the station will deliver the Window Observational Research Facility (WORF), which will provide a new facility dedicated to multi- and hyper-spectral remote sensing and high resolution Earth observation photography to enhance the use of the best optical-quality window ever flown in space, in the U.S. Destiny Laboratory.

Soaring high over the Earth in the International Space Station, the astronauts and cosmonauts of the Expedition 22 crew began a new week Monday, the final week in space for two of their number. Commander Jeff Williams and Flight Engineer Maxim Suraev will depart the station Thursday aboard the Soyuz TMA-16 spacecraft. They will undock from the orbiting complex and take a three-and-a-half-hour ride that will culminate in a parachute-assisted landing on the steppe of Kazakhstan early that morning. Williams and Suraev began their final week in orbit by testing the Soyuz spacecraft’s motion control system and recharging the satellite telephone they will carry with them in the unlikely event that they land off course in the barren landing region and need to contact search and recovery forces. They also spent three hours going over procedures for their homeward flight with specialists on the ground. As members of the Expedition 21 and 22 crews, Williams and Suraev will have spent 169 days in space. Including his time on the Expedition 13 and STS-101 crews, this will give Williams a total of 362 days in space, placing him fourth on the all-time U.S. list of space travelers behind Peggy Whitson with 377 days, Mike Foale with 374 and Mike Fincke with 366. Williams will be 26th on the all-time endurance list for all space travelers. Expedition 22 Flight Engineers Soichi Noguchi, T.J. Creamer and Oleg Kotov will continue their stay on the station becoming the new Expedition 23 crew. Kotov will become the new station commander when the departing Williams enters the Soyuz vehicle and closes the hatch. On April 4, Expedition 23 will expand to a six-member crew. Arriving in the Soyuz TMA-18 spacecraft will be new station crew members Alexander Skvortsov, Tracy Caldwell Dyson and Mikhail Kornienko. On April 7, space shuttle Discovery is scheduled to arrive for a thirteen day mission to supply the station with new science racks and ammonia tanks. STS-131 will feature three spacewalks and the delivery of the Leonardo Multi-Purpose Logistics Module. In preparation for the joint spacewalks to be performed during STS-131, Creamer and Noguchi packed up equipment for Discovery to return to Earth and Noguchi performed maintenance on the cooling loops in the U.S. spacesuits housed in the station’s Quest airlock. Controllers on the ground operated Canadarm2, the station’s robotic arm, to remove the Special Purpose Dextrous Manipulator, known as Dextre, from the Mobile Base System (MBS) on the complex’s truss structure. Tuesday they will move it to the outside of the Destiny laboratory in order to make the MBS available for use during STS-131.
ABOUT AMATEUR RADIO
Amateur radio service is defined in the Communication and Multimedia (Spectrum) Regulations 2000 as a radiocommunications service (covering both terrestrial and satellite) in which a station is used for the purpose of self traning, intercommunication and technical investigations carried out by authorized persons who are interested in radio technique solely with a personal aim and without any pecuniary interest.
AMATEUR RADIO OPERATOR'S CERTIFICATE
Regulation 27(1) of the Communications and Multimedia (Technical Standards) Regulations 2000 states that no person shall undertake or conduct any activity in designated skil area unless that person is certified. Amateur radio operator has been gazetted as a designated skill area category under the regulation, hence to operate an amateur radio station a person needs to have an appropriate proficiency and skill i.e. certified in this area.
INTERFERENCE
Please ensure that the radio transmision does not cause interference to any other radio services. Regulation 15(1) of the Communications and Multemedia (Technical Standards) Regulations 2000 states that no person shall intentionally design, install, operate, maintain or modify any communications equipment in a manner is likely to cause interference with, impairment, mulfunction of, or harm to any communications equipment or any other equipment.
Regulation 15(2) of the regulation denotes that a person who contravenes this regulation commits an offence and shall, on conviction, be liable to a fine not exceeding three hundred thousand ringgit (RM 300,000.00) or to imprisonment for a term of not exceeding three years or to both.
To eliminate the potential of interferences, the following procedures must be followed strictly:-
a) Ensure that suffient equipment, tools and test gear is available and can used to monitor and verify that your transmission does not cause any interference to other radio services.
b) You must responsible if your amateur radio is found to be the caused of interference. Immediate remedy action must be taken to rectify the problems in case of interference.
c) Ensure that the transmission do not exceed the level of over deviation.
d) Ensure that the radiated energy is always within the narrowest posible frequency bands for any class of emission in use.
e) The radiation of harmonics and spurious emissions should be suppressed to minimize interference.
Historical Description of Amateur Radio: From the Encyclopedia Britannica:-
Interest in amateur radio arose around the turn of the century, shortly after the Italian inventor Guglielmo Marconi successfully sent the first transatlantic wireless signal in 1901. The interference of amateur broadcasts with commercial and military transmissions led to the institution of government control in 1911. After World War I, amateurs became active in radio experimentation, contributing to developments in long-distance broadcasting and becoming the first radio operators successfully to exploit the upper medium-frequency and lower high-frequency radio bands. Over the years, amateur radio operators have also provided emergency communications during forest fires, floods, hurricanes, and other disasters. They serve as an important link between stricken communities and the outside world until normal communications are reestablished.Amateur radio operators in the United States are subject to international and federal regulations. There are five classes of licenses. Competence in the use of the International Morse Code and a knowledge of radio theory and regulation are required to obtain the advanced-level licenses. Amateur radio is allocated frequencies at the extreme high-frequency end of the medium-wave band, five groups of frequencies in the shortwave band, two groups in the veryhigh-frequency band, three in the ultrahigh-frequency band, and seven in the superhigh-frequency band for telegraphic and telephonic communication using amplitude and frequency modulation. There are restrictions on the power of the transmitters, and certain of the frequencies must be shared with due regard for the needs of other users.
