Sirius CEO Mel Karmazin appeared before a newly formed Antitrust Task Force, a sub-committee of the House Judiciary Committee, on Wednesday last week in Washington, D.C. to defend the proposed U.S. merger between XM and Sirius satellite radio services.

The hearing, carried live on C-SPAN, was attended by representatives from various competing broadcast companies. The representatives challenged the merger deal, and some speakers were openly hostile to Karmazin and to satellite radio in general, while other speakers were more civil.

Several times during the debate, the discussion centered on the failed merger deal between the two satellite television networks DirecTV and Echostar. The comparison between this proposed radio merger and the failed television merger was settled to some extent with an understanding that nearly all television viewers now use either cable or satellite to view available programming. Televised programming content is now delivered mainly in the form of a subscription, rather than airwave transmissions.

Unlike television programming, most radio listeners use over the air receivers to listen to free programming content supported advertisers.

“We come to this hearing with an open mind, but we recognize that the companies have the obligation to convince the Congress, the regulators, and most importantly, the American People that this combination will improve the competitive playing field and benefit consumers,” said John Conyers, the sub-committee chairman. To determine the legality of this merger, Congress first needs to decide whether a combined XM and Sirius would be a monopoly, as the only satellite radio provider in the United States, or whether the new company will actually be in competition with other forms of radio-like entertainment, according to Conyers. The hearing focused on alternatives such as Internet radio, terrestrial radio, portable audio devices, and emerging services, such as cell phone services and WiMax.

Naledi Pandor, Minister of Science and Technology in South Africa, publicized results of a study on Tuesday on the role of women in the fields of science and technology in the country. Though women only make up thirty-three percent of publishing scientists in the country, their numbers have increased in recent years. When compared to a similar study from 2004, trends show increased enrollment of women in higher education.

Pandor was disappointed by the dearth of individuals that attended the announcement of the results of the study at the Parliament of South Africa. “It shows the degree to which science does – or doesn’t – matter to South Africans,” said Pandor. Prior to her role as Minister of Science and Technology, Pandor had served as Minister of Education of South Africa.

Professor Anusuya Chinsamy-Turan, a woman scientist in South Africa, commented to News24 that some educational organizations in the country were “really, really hostile to women”.

Pandor highlighted problems affecting women and specifically black women in the country from increased participation in science, including “financial difficulties before and during tertiary studies, gender stereotyping, legacies of disadvantage in black communities, negative dynamics at workplaces, and the lack of attention to women’s specific needs”.

Women in the country are advancing against men in science fields, particularly engineering, agricultural studies and biology. At present there are a greater number of women than men among enrollments for degrees in higher education, and among individuals obtaining those degrees. According to The Times, “their biggest gain has been in health sciences, where women earned more than half the doctorates awarded in 2005”. Pandor emphasized a current need for additional women to enter the fields of technology and engineering.

The announcement at Parliament in South Africa was part of the launch of the “Facing the Facts 2009” booklet, which was published by a sub-committee of the National Advisory Council on Innovation (NACI), Science, Engineering and Technology for Women (SET4W). Dr. Romilla Maharaj of SET4W presented the report to Parliament, and stated that enrollment by women in higher education had increased by one percent from a previous study. Dr. Maharaj noted that women were still currently in the minority among individuals with degrees in higher education.

After having its launch delayed three months due to damage caused by hail stones during a storm, Space Shuttle Atlantis has been given the green light by NASA to launch on June 8.

“NASA’s senior managers have signed the Certification of Flight Readiness confirming that Space Shuttle Atlantis, her flight crew and payloads are fit to fly,” said a statement posted on NASA’s website.

Atlantis’s main engines, orbital maneuvering system and forward reaction control system was pressurized this past weekend and the crew’s equipment has been put into stowage.

NASA plans to launch Atlantis despite a vote reached by the International Association of Machinist and Aerospace Workers, IAMAW, a union that is representing 570 workers that work with the shuttle program, but according to a union spokeswoman, the strike is not going to affect the launching of Atlantis.

“The bottom line is, a strike would not affect the next launch or the next one after that,” said IAMAW spokeswoman, Tracy Yates. The union voted down a contract because the workers believed that NASA’s wage offer is “substandard.”

Atlantis will deliver equipment to the International Space Station and to make repairs to it. Commanding Atlantis for its mission will be Rick Sturckow and Lee Archambault will serve as Atlantis’ pilot. Mission Specialists James Reilly, Steven Swanson, John Olivas and Flight Engineer Clayton Anderson round out the crew to deliver the S3/S4 starboard truss segments, batteries and another pair of solar arrays to the space station.

They are cheap, useful, and very plentiful, and that is exactly the problem, according to researchers. A report issued on Feb. 23 by a cadre of environment and economics researchers suggested that Kenya should ban the common plastic bag that one gets at the checkout counter of grocery stores, and place a levy on other plastic bags, all to combat the country’s environmental problems stemming from the bags’ popularity.

The world’s Large Hadron Collider accelerated its protons to an energy of 1.18 TeV at 00:44 GMT+1 today. This set a new world record, surpassing the 0.98 TeV record set at the Fermi National Accelerator Laboratory‘s Tevatron collider, which was commissioned in Chicago in 2001. The event came ten days after the LHC collider restart.

Yesterday at 20:48 UTC, one proton beam was accelerated to 1050 GeV (1.05 TeV) in LHC. Three hours later, the next record was set by two beams of opposite direction, 1.18 TeV each.

The CERN researchers are delighted with the quick progress and are happy with the excellent performance of the machine. Steve Myers, director of accelerators and technology at the Cern particle physics laboratory near Geneva, commented on LHC optimistically, comparing it with the twenty-year old Large Electron-Positron Collider (LEP): “I was here 20 years ago when we switched on Cern’s last major particle accelerator, LEP. I thought that was a great machine to operate, but this is something else. What took us days or weeks with LEP, we’re doing in hours with the LHC. So far, it all augurs well for a great research programme.”

High proton beam energy is needed to get many proton-proton collisions. However, all elements of the system need to be monitored carefully, and sudden energy increases are undesirable to ensure that the machine operates within normal parameters, in order to avoid a repeat of the superconductive magnet quench and consequent six-tonne liquid helium leak catastrophe on September 19, 2008, nine days after the first start. The damage caused by the leak, and the subsequent repairs and upgrades to the LHC that were needed, caused a delay of more than a year in the commissioning of the collider.

“We are still coming to terms with just how smoothly the LHC commissioning is going. It is fantastic. However, we are continuing to take it step-by-step, and there is still a lot to do before we start physics in 2010” said Cern’s director general Rolf Heuer.

NASA officials have decided to call an end to the Mars Phoenix Mission, after winter took hold of the red planet. NASA calls the mission a total success.

“Phoenix has given us some surprises, and I’m confident we will be pulling more gems from this trove of data for years to come,” said Phoenix Principal Investigator Peter Smith of the University of Arizona in Tucson, Arizona in a statement on NASA’s website.

The Phoenix lander last sent a signal to Earth on November 2. NASA says that colder temperatures, lack of sunlight and increased dust particles on the lander’s solar arrays has stopped its on board batteries from charging, causing the instruments to fail.

Despite the news, Phoenix had operated two months longer than scheduled. The lander had been operating for over five months.

Phoenix was responsible for several discoveries on Mars, including the confirmation of the presence of water-ice, which had previously only been detected from space.

“Phoenix provided an important step to spur the hope that we can show Mars was once habitable and possibly supported life. Phoenix was supported by orbiting NASA spacecraft providing communications relay while producing their own fascinating science. With the upcoming launch of the Mars Science Laboratory, the Mars Program never sleeps,” said Doug McCuistion, director of the Mars Exploration Program.

NASA officials will continue to listen for a signal from Phoenix, in hopes that it will phone home again in the near future.
