Yesterday, NASA announced their spacecraft Juno has reached Jupiter orbit. It was launched almost five years ago to investigate the largest planet of the Solar System, especially its past.

Charles Bolden, NASA administrator, said, “Independence Day always is something to celebrate, but today we can add to America’s birthday another reason to cheer — Juno is at Jupiter”. He also added the spacecraft would help study the evolution of the Solar System and explore Jupiter’s radiation belts.

NASA spent US$1.1 billion for Juno. The Jet Propulsion Laboratory (JPL) reported Juno was confirmed in Jupiter’s orbit at 0353 UTC. Including the camera, the probe has nine scientific instruments. Juno has covered 2.7 billion kilometres (1.7 billion miles) to reach Jupiter.

NASA said non-essential equipment was turned off for the approach. They expect photos in some days. The first orbital revolution period is 53 days. Juno is expected to orbit the planet 37 times keeping an altitude of 5000 kilometres (3100 miles) above the Jovian clouds and then fall into the planet in 2018.

NASA’s Galileo, launched in 1989, found evidence of saline water on Jovian satellites Europa, Ganymede, and Callisto.

The electronics have been encased in titanium to protect them from high-energy radiation.

In the lead-up to the 2008 Canadian federal elections much speculation was made about environmental issues and initiative, with various parties maneuvering to claim some portion of the green mantle. But it was the Liberal party which first brought a full-blown policy to the public.

In the months since the Green Shift initiative was brought forth, the political pundits and activists have both talked about this year as the first election where the environment would be a major issue on the minds of voters, and possibly a decisive one for the electorate.

It’s indeed true the environment ranks very high in minds of voters across the country, particularly among young voters. One national survey of Canadians between 18 and 25 finds the environment is the top issue. A poll of all voters found it to be the third most important single issue over all, behind the economy and health care, but the poll suggested that no one issue has really caught the attention of the electorate with many issues gaining similar attention.

The parties themselves seem indecisive, trying to claim a focus on environmental issues but rarely making specific proposals or promises, with the notable exception of the Liberals whose platform has been targeted by opponents and commentators as “wildly experimental” and “doesn’t go deep enough” by turns.

Examining the platforms of the New Democratic Party regarding air pollution and global warming as available on their website, one is struck by a lack of substance. Reference is made to C-377, the Climate Change Accountability Act, which the NDP calls “Layton’s Kyoto-Plus Bill”, which was passed in 2006. The party believes Canada can achieve its Kyoto requirements by 2012, though no mention is made of how a Layton government would do so.

In June of 2008 the Liberals tabled a plan, the Green Shift, which they claim would reduce Canada’s greenhouse gas emissions 20% under 1990 emissions – well below the 6% required by Canadian law when Canada ratified the Kyoto Accord – by 2020, which is rather after the 2008-2012 phase-in period required by that same law. The method of performing this reduction would be to shift the Canadian tax system, reducing income and revenue taxes by replacing them with taxes on greenhouse gas emissions. The plan generated considerable discussion and opposition, and the party has back-pedaled in some portions and added on in others, as well as announcing a couple of separate initiatives to soften the effects for farmers, homeowners, and fishermen among others.

A more diverse approach than solely a “Carbon Tax” is proposed in the Green Party’s platform, which presents an almost holistic approach of adherence to the Kyoto obligations, “Cap and trade” of carbon emissions, industry development with both green technology R&D and regulation as well as consumer subsidies, and their own version of a carbon tax. Alone of the parties they specifically mention the role of international diplomacy/trade as a part of their approach.

Such an approach appears to be anathema to the Conservatives, whose mantra since their election has been that Kyoto cannot be complied with without forcing an economic recession on the country, and used the Throne Speech of 2007 to reiterate that position. They have opposed cap-and-trade schemes in the past, but their platform for this election states their plan to reduce greenhouse gas emissions includes emissions caps for “four air pollutants commonly associated with smog and acid rain,” as well as “tough emission reduction targets”.

In contrast to the laundry-list of unconnected initiatives on the Conservative’s website, the clean platform pamphlet created by the Bloc Québécois makes a simple and apparently heartfelt statement on the environment:

La lutte aux changements climatiques est devenue un enjeu fondamental pour l’humanité et le Québec est déterminé à apporter sa contribution, à sa façon. À Ottawa, c’est le Bloc Québécois qui mène la lutte en faveur de l’application du protocole de Kyoto dans le respect des choix du Québec.

Tackling climate change has become a fundamental issue for all of humanity and Québec is determined to make its contribution, in its own way. In Ottawa, the Bloc Québécois, respecting Québec’s choices, is leading the fight to enforce the Kyoto Protocol.

Just how they plan to enforce the Kyoto obligations is not stated, though they do discuss a carbon market, and tax incentives for home heating upgrade and transportation.

There seems to be a wide if somewhat shallow interest in the electorate as to just what each party is offering on the environmental file. But with sketchy platforms regarding environmental issues, it’s no wonder some of the parties have turned to the subject of economics in recent days.

A US Coast Guard official said today that BP’s latest effort to plug the Gulf of Mexico oil spill has been successful in slowing the amount of oil leaking from the well.

The official, Admiral Thad Allen, said that the procedure, known as a “top kill” operation, has been able to block some of the leaking oil at the source, the top of the damaged well. The operation involves pumping material into the well to plug the leak before cement is used to permanently seal the leak. Allen said the operation has “been able to force mud down and not allow any hydrocarbons to come up.”

BP hasn’t confirmed the success of the top kill operation, saying only that the “operation is proceeding as we planned it,” and that there had been no major incidents thus far. Although the possibility of failure is still present, experts say that the longer the procedure continues, the less likely it will be that anything goes wrong.

The procedure began yesterday afternoon, after diagnostics on the damaged equipment on the ocean’s surface indicated that it could withstand the added pressure of the mud being pumped into the well. Although engineers involved with the operation wore concerned that the pressure of the mud might not be able to overcome that of the oil, that has thus far not been the case.

Separately, a group of US scientists announced new estimates of how much oil was flowing from the well, ranging from 12,000 to 25,000 barrels a day, far higher than BP’s original estimate of 5,000 barrels a day, a figure which BP warned was possibly inaccurate.

In a press conference Thursday afternoon, US president Barack Obama also announced new measures in response to the spill, which include:

• Suspending off-shore test drilling for six months
• Extending the moratorium on issuing drilling permits for an additional six months
• Cancelling the sale of leases for off-shore drilling.

In statements, Obama criticized the “scandalously close relationship” between government officials and oil companies in the past, saying that the Mineral Management Service, which is the agency responsible for monitoring off-shore drilling, had been corrupt for years.

Tuesday, February 8, 2005 Microsoft has announced that it plans to purchase antivirus firm Sybari Software in order to expand its market within the computer security market. The takeover comes after Microsoft purchased Romanian security firm GeCad in 2003 and two months after an announcement that it is to acquire anti-spyware vendor Giant-Company Software.

Sybari is a private company based in East Newport, New York that develops antivirus software which can be used with Microsoft’s Exchange software, as well as with the Lotus Notes system.

This takeover is seen by analysts to be hostile move on Microsoft’s part, as it places the software giant in direct competition with market leaders Symantec and McAfee. Sterling Auty, an analyst with JP Morgan, told Reuters that he estimated that Microsoft could be competing for up to five percent of Symantec’s business and up to eight percent of McAfee’s revenue.

Microsoft’s shares rose $0.10 at midday to $26.26, while both McAfee and Symantec shares fell.

The discovery of the presence of airborne asbestos in a middle school in Montclair, New Jersey Friday prompted the evacuation of over 200 students from the school and the school’s closure. Renaissance Middle School, part of the Montclair Public Schools in New Jersey, was closed Monday and remains closed Tuesday while undergoing asbestos testing and cleaning.

According to a letter sent home to parents by the Superintendent’s Office of Montclair Public Schools on Friday, “plaster may have been disturbed” during construction on new fire doors at the Renaissance School building on Thursday.

An inspection arranged by the school district indicated asbestos was present in the plaster, and a subsequent inspection performed by asbestos consultant Detail Associates revealed “a level of airborne asbestos fibers that exceeded the acceptable range” in the third floor hallway of the school. Montclair Public Schools business administrator Dana Sullivan told The Star-Ledger that testing conducted on March 31 revealed the presence of asbestos in a brown undercoating of plaster at the Renaissance School building.

The affected area was sealed off, and some students were moved to other areas of the building while others were moved to off-site locations. District Public Information Officer Laura Federico told The Montclair Times that sixth and seventh graders were transported to Hillside Elementary School, and eighth graders were bussed to Montclair High School. “The safety of our students and staff is always our first concern,” said Federico.

According to The Montclair Times, Detail Associates conducted a cleaning protocol at the school on Saturday and tested the building to make sure it did not contain unacceptable levels of asbestos fibers. The letter sent to parents Friday by the Superintendent’s Office said that Detail Associates had told the district that the building would be “cleaned, tested and cleared for occupancy by Monday morning”. The school remained closed Monday, and a meeting was held between parents and school district officials. A Parent-Teacher Association meeting is planned for Wednesday night.

The Star-Ledger reported that the ongoing asbestos cleanup of the school is being supervised by the state Department of Environmental Protection. At the meeting Monday morning between parents and school district officials, parents demanded that the inside of lockers be included as part of the asbestos cleanup. This additional step in the asbestos inspection process prompted the school’s closure Tuesday. A Monday statement by the Business Office of Montclair Public Schools said that the Renaissance School would remain closed Tuesday for sixth and seventh grade students “so that an extensive cleanup and additional asbestos testing can be completed”. Eighth grade students did not have classes scheduled as a trip to Washington, D.C. had previously been planned; the school trip is unaffected by the recent asbestos incident.

Steve Jaraczewski of Detail Associates was present at the district meeting Monday, and said that one of four test samples taken at the school was positive for the presence of airborne asbestos at over six times acceptable levels. Jaraczewski was critical of the asbestos management plan provided by Roman Catholic Archdiocese of Newark, which owns the school’s building and leases it to Montclair Public Schools.

Jaraczewski said that the state Department of Environmental Protection has required asbestos management plans since 1988, but that the company that drafted the asbestos plan for the Archdiocese of Newark is out of business. Representative for the archdiocese Jim Goodness emphasized that the building would be back open for classes soon. “The kids will be able to go back to school soon, and that’s the important part,” said Goodness.

Exposure to airborne asbestos can lead to mesothelioma, a cancer which develops in the sac surrounding the lungs and chest cavity, abdominal cavity, or the sac surrounding the heart. Exposure to disturbed asbestos fibers can also lead to lung scarring, a condition called asbestosis, and lung cancer. Patients with malignant mesothelioma generally do not have positive outcomes, and once diagnosed have six months to a year to live.

Space transport services company SpaceX launched their fifth Dragon resupply vehicle to the International Space Station yesterday. The spacecraft — containing more than 2,200kg (5,000 pounds) of food, experiments, and spare parts — successfully decoupled from the launch rocket and should reach the station early tomorrow.

The launch was postponed from Tuesday because of a technical issue on the second stage of the rocket. The shipment includes replacements for cargo aboard the spaceship Cygnus, destroyed during a failed launch in October. Cygnus belonged to the rival Orbital Sciences Corporation.

SpaceX tried unsuccessfully to land the Falcon 9 delivery rocket for reuse. The rocket reached an unmanned barge in the Atlantic, but landed too hard. SpaceX CEO Elon Musk said the landing “bodes well for the future, though”. The attempted salvage of the rocket was experimental, using new retractable fins. Next time they will add extra hydraulic fluid, Musk said.

The ship’s support equipment was damaged but, according to Musk, the barge is intact. Last year saw two successful SpaceX splashdowns but landing on such a small target as a ship is unique.

Brazil —Former advisors to Brazilian Minister of Finance Antonio Palocci have claimed that three million US dollars from Cuba were used in the 2002 political campaign of Luiz Inácio Lula da Silva. The accusation was printed by the Brazilian magazine Veja in its issue circulating this week.

According to Veja, Rogério Buratti, Palocci’s secretary in the early 1990s during the period when Palocci was mayor, claims that Ralf Barquete (another advisor to Palocci) had asked him to find a way to bring money from Cuba.

Another source, economist Vladmir Poleto who had also worked for Palocci, claimed to have brought the three million from Brasília to Campinas by plane. He stated the money was hidden in whiskey boxes: Johnnie Walker Red Label and Black Label and Havana Club (a Cuban brand of rum). Barquete received the money at the Campinas airport Viracopos. Afterwards he claims the money was transferred by car to São Paulo and delivered to Workers’ Party treasurer Delubio Soares.

Workers’ Party President Ricardo Berzoini has responded saying that the accusation is false. And Lula’s aide Gilberto Carvalho has said the story is “absurd”.

According to the blog of Folha de S. Paulo reporter Josias de Souza, Palocci and Lula are worried about the interviews being aired on Brazilian television.

The president of the PPS, federal deputy Roberto Freire (Pernambucostate), has stated that his party will ask the Electoral Justice investigatory agency and the Public Ministry to begin a investigation into the charge. The parties PFL and PSDB are also considering demanding an investigation.
