Mars rover engineers have built a test bed simulating the condition of the Mars Rover Opportunity, which became stuck in a Martian sand dune on April 26. The test bed uses a combination of materials including play sand for children’s sandboxes, diatomaceous earth for swimming pool filters, and mortar clay powder.

Opportunity dug into soft sand to wheel-hub depth as it drove over a dune about one-third meter (one foot) tall and 2.5 meters (8 feet) wide. “We’ve climbed over dozens of ripples, but this one is different in that it seems to be a little taller and to have a steeper slope, about 15 degrees on part of its face,” said Mark Maimone, a Jet Propulsion Laboratory (JPL) rover mobility engineer. Tests will be conducted using an Earth-bound twin of the rover and the simulated Martian dune to determine how to best maneuver Opportunity out of the predicament before transmitting commands to the actual vehicle.

“We choose to proceed cautiously, so we don’t expect to begin actually driving out of the dune before next week, possibly later,” said Jim Erickson, rover project manager at JPL. “Both Opportunity and Spirit have already provided many more months of scientific exploration than anyone expected. By taking good care of them, we hope to keep them exploring for more months to come. Tests so far have sustained our optimism about Opportunity’s ability to drive out of this dune, but we have more testing ahead to understand how robust that capability is.”

Engineers constructed a simulated dune last week using sand that was already at JPL’s rover testing facility and put a test rover into a similar dug-in position. The test rover had no difficulty driving away, even when sunk belly-deep. However, that sand offered better traction than the finer, looser material that appears to make up the surface at Opportunity’s current position. “We needed to do tests using material more like what Opportunity is in, something that has a fluffier texture and cakes onto the wheels,” said JPL rover engineer Rick Welch, who is leading the tests.

Based on images of wheels and wheel tracks from Mars, Dr. Robert Sullivan of Cornell University, a rover science team member, working with engineers in the JPL test bed, helped match the properties of the test sand as closely as possible with those of the sand beneath Opportunity, “We found that when the wheels dig in, the material we’re using does stick to the wheels and fills the gaps between the cleats, but it doesn’t stick when you’re just driving over it. That’s good because it’s the same as what we see in the images from Opportunity,” Sullivan said. Experiments show that the test rover, after some initial wheel-spinning, can drive out of the more powdery material.

The team went to several home supply and hardware stores to find enough bags and boxes of the ingredients to make more than 2 tons of the simulated Mars sand for the more realistic mobility tests, according to JPL rover mobility engineer Jeff Biesiadeckia.

New Paltz, New York — More than 350 U.S. students took part in a demonstration Friday outside the SUNY New Paltz Student Union Building where student leaders used a bullhorn from the rooftop to rally the gathering on the concourse below. University police dispersed student leaders from the roof which was followed by more than 100 students storming the Haggerty Administration Building (HAB).

During the 2004–2005 academic year, students lobbied for a $10 million renovation project for their Student Union Building, which has not been renovated since its construction more than 30 years ago.

HAB spokesman Eric Gullickson said that the supplemental appropriation for the project is the largest in the history of the college and that the six-member advisory committee includes three students but that; “the Student Association, which was offered the first seat on this committee, declined the opportunity,” Gullickson said.

Student leaders, including Student Body President R.J. Partington III and Student Senate ChairJustin Holmes, who played a role in organizing this demonstration, testified during the Spring 2005 semester before the New York State Assembly Committee on Higher Education, eventually winning the renovation project. Holmes says that Gullickson’s assertions are; “an out-and-out lie. The SA was never offered such a seat. We were offered 1 seat on a seven seat committee, with the administration selecting the other six members.”

The major arguments for a capital project on the Student Union Building were that it:

• did not accommodate organizations and organization office needs
• lacked crucial technology for student mobilization
• was built for a student population less than half the size of 2005, and
• was one of the longest standing Student Unions in the SUNY system which had not undergone a renovation

During the Fall 2005 semester the HAB claimed that it would oversee the renovation project, citing the need for a larger lobby and bookstore.

The Kingston Daily Freeman reported:

The crystallizing issue for the demonstration was the upcoming $10 million renovation of the Student Union building. The renovation, scheduled to begin in about two years, will be the first major change to the building since it was built 34 years ago, according to college spokesman Eric Gullickson, who said the supplemental appropriation for the project in the state budget is the largest in the college’s history.

Gullickson also said that a six-member committee had been formed to guide the design process, but student leaders, including Partington, were told that the proposed committee would be seven members, including four non-students and two students who were appointed by the HAB.

“No matter the size and makeup of the HAB’s so-called renovation committee, it has nothing to do with the actual renovation process, which will be administered by a student committee, with input from other parties of course considered,” responded Holmes.

During the Fall 2005 semester, Student Body President R.J. Partington III attempted to negotiate with Administrators, including HAB President Steven G. Poskanzer, over the project.

The HAB refused to concede to student demands.

At this point, the Student Senate passed legislation proclaiming that the project would be overseen by a committee where students constitute a majority, and Partington announced that he “did not recognize and would not sit on” any committee that did not meet the needs of students.

Vice President of Acacdemic Affairs & Governance, Stephanie Adika said, “If the HAB won’t even listen to us about our own building, how are they going to listen to us about all the other problems the students have with SUNY New Paltz.”

Pirates in Somalia have released the MV Faina, a Ukrainian ship carrying a cargo of 33 T-72 tanks, along with 20 of its crew of 21, the Russian captain having been killed by hypertension during the hijack.

A ransom of US$3.2 million was paid for the ship’s release, compared to the $20 million previously demanded and also down from the initial request for $35 million after the capture in September. By January 16 the ransom sought was $5 million, with negotiations occurring directly between the pirates and the ship’s owner. In October the pirates threatened to blow the ship up unless this was paid within days, and stated they were willing to die and take the crew with them, but this threat was never carried out.

The ransom came in on Wednesday, and after counting the money the pirates left the vessel on Thursday. One pirate, Segule Ali, said of the payment that “no huge amount has been paid, but something to cover our expenses.”

The ownership of the cargo, which includes ammunition, rocket launchers, small arms and spare parts as well as tanks, is uncertain. Although the shipment was said to be for Kenya, as acknowledged by the Kenyan government, the pirates claim to have documents proving they were destined for Sudan, currently the subject of a United Nations arms embargo. Sudan denies this.

At one point, with the ship anchored off Harardhere, the pirates claimed they had put down an attempted revolt by the crew. However, the Faina’s owner has expressed doubts about the veracity of this report, which originated with the pirates themselves.

The remaining crew are reported to be healthy by the Ukrainian Presidency and the ship is now heading to Mombasa under US Navy escort. There are 17 Ukrainians, two Russians and a Latvian on board.

Neverland Valley Ranch, owned by Michael Jackson, is to be sold at auction on March 19, 2008, unless Jackson pays over US$24 million.

Financial Title Company, the trustee of his Santa Barbara County, California, home and amusement park, has foreclosed on the property. They notified Jackson of the foreclosure and sale on Monday. Jackson had only just recently paid an overdue property tax bill of $600,000.

The court filing, addressed to Jackson, says, “You are in default of a deed of trust … Unless you take action to protect your property it may be sold at a public sale.” Fox News published the filing.

The foreclosure includes the ranch and all possessions on the property, inside or out.

The foreclosure auction will take place in front of the Santa Barbara County Courthouse in Santa Barbara. Jackson has until then to pay $24,525,906.61 he owes the title company.

In 2006, Jackson refinanced previous loans that had been bought up by Fortress Investment Group. The $300-million loan was secured with the aid of Sony Music Entertainment. However, the Neverland property was not part of that deal.

Jackson has not lived at Neverland since June 30, 2005, when he moved to Bahrain after a rape charge and subsequent acquittal.

Rumours in London and Merseyside have linked Paul and Oliver Collyer, creators of the football management series Championship Manager, with a possible bid for Premiership football team Everton.

The Goodison Park club, under the chairmanship of former Coronation Street actor Bill Kenwright, were subjects of a failed takeover bid in August 2004. After suffering the blow of failing to get beyond the qualifying stage of the Champions League, Kenwright is known to have recently sought additional investments in the club.

While a move is not thought to be imminent, the recent takeover of the brothers’ games development company Sports Interactive by game giant SEGA could well prove the catalyst for action by the lifelong Evertonians. The company’s PR guru Miles Jacobson was forced into an official denial of the story soon after the takeover news broke on Tuesday morning. The Collyers themselves have as yet been unavailable for comment.

New currency notes are being introduced in Ghana today. The new currency, to be called the Ghanaian cedi, replaces the previous cedi which has been in circulation since 17 February, 1967.

The Ghanaian cedi will be exchanged at 10,000 old cedis to one new Ghanaian cedi. The exchange rate against the U.S. dollar starts at GH¢0.92 to one U.S. dollar. The new ISO code for the currency is GHS, and the new symbol, GH¢.

The change, which was originally scheduled by the Bank of Ghana to start on July 1, 2007, will instead start on Tuesday July 3, as the original date is Ghana’s Republic Day.

Monday, July 2, was declared a public holiday as the actual Republic Day fell on a Sunday. July 3, is thus the first day that the currency will be available to the public as banks open to the general public. This is because ATMs were shut down over the weekend so that the currencies could be checked and replaced in all of them nationwide. The old and new currencies will be used concurrently until the end of December 2007, when the old currency will cease to be legal tender.

This is the third Ghanaian cedi to be introduced in the country since 1965.
