On Monday shortly before noon US west coast time (2000 UTC), NASA’s InSight lander successfully touched down on Elysium Planitia on Mars. It sent a signal beep and image of the surface of Mars to the Jet Propulsion Laboratory in California.
The lander used aerobraking with a heat shield, then a parachute and finally rockets to achieve a soft landing on the surface. It used similar entry, descent, and landing sequence to the Phoenix spacecraft.
Insight project manager Tom Hoffman said, “We hit the Martian atmosphere at 12,300 mph [miles per hour; 19,800 kilometres per hour], and the whole sequence to touching down on the surface took only [six and a half] minutes […] During that short span of time, InSight had to autonomously perform dozens of operations and do them flawlessly — and by all indications, that is exactly what our spacecraft did.”
InSight stands for Interior exploration using Seismic Investigations, Geodesy and Heat Transport. The lander’s two-year mission is to assess what Mars is like underground, determining the planet’s heat flow and listening to the reverberations of groundquakes and meteorite impacts.
Acting director of NASA’s Planetary Science Division Lori Glaze said, “We’ve studied Mars from orbit and from the surface since 1965, learning about its weather, atmosphere, geology and surface chemistry […] Now we finally will explore inside Mars and deepen our understanding of our terrestrial neighbor as NASA prepares to send human explorers deeper into the solar system.”
InSight is expected to begin its mission in a few months, once it has placed the equipment on the surface of Mars. Its solar panels are now open, catching sunlight and powering the spacecraft. It is equipped to drive a device up to 16 feet (5 meters) down into Mars’s surface, a record for Mars probes. This is to help characterize heat flow from the planet. Insight also has ultra sensitive seismometers which it is to use to detect Mars earthquakes for the first time. By recording the seismic waves from these quakes, InSight would help scientists infer things about the interior of Mars, such as how seismically active it is. InSight has as single seismometer, with which NASA plans to assess signals from different types of vibrational wave, triangulate their sources, and so derive information about the planetary interior.
InSight was launched May 5 of this year and traveled reportedly 301,223,981 miles (somewhat over 484,773,000 kilometres) between planets followed by two suitcase-sized cube satellites called Mars Cube One, individually MarCO-A and MarCO-B, which relayed information to Earth during the landing process.
Previous successful landers on Mars include Viking 1, Viking 2, Pathfinder, Spirit, Opportunity, Phoenix, and Curiosity. Of these, only Curiosity is still in communication with Earth, after NASA lost communication with Opportunity in June. InSight’s landing spot in the Elysium Planitia is about 600 km from Curiosity’s landing site in Gale Crater.

Thailand’s prime minister, Abhisit Vejjajiva, has ruled out a compromise offer by anti-government protest leaders for parliament to be dissolved in thirty days, with elections to be held in 90 days.
In a televised address on Sunday, with army chief General Anupong Paochinda at his side, the prime minister dismissed the offer made by the National United Front of Democracy Against Dictatorship (UDD), saying such issues could not be resolved in such a short period of time, and “because they use violence and intimidation. I cannot accept this.”
Abhisit said the government stood by an offer made during earlier talks with the UDD for the house to be dissolved within the next nine months.
In reaction, the UDD, also called the Red Shirts, maintained an earlier call for parliament to be dissolved immediately. The UDD also withdrew from any further negotiations with the government. UDD leaders have repeatedly warned supporters rallying in central Bangkok’s retail and business areas of the threat of a new government crackdown.
There have been two large incidents of street violence in the past month or so, resulting in 26 deaths and injuries to hundreds of people. The Red Shirts primarily consist of supporters of former prime minister Thaksin Shinawatra, ousted in a 2006 coup. He was later given a two-year prison term on charges of corruption, although Shinawatra left the country in self-exile to avoid being jailed.

Dutch adventurer Ralph Tuijn has reached the halfway point of his attempt to be the first person to row across the Pacific Ocean unaided.
The 16,000 kilometre journey from the coast of Peru to the seaside city of Brisbane, Australia, the widest section of the Pacific, has never been crossed absolutely unaided by a rower, and Tuijn says just nine people have rowed it even with assistance.
Tuijn reached the central point of his crossing, an insignificant point of water in the ocean, 111 days after setting off from Peru in March. He has been making good progress, and has since cut his estimated time of arrival in Brisbane by a month.
The Dutchman, who now expects to reach his destination on October 20, has kept in touch with those tracking his movements through daily internet postings from his laptop computer, including his wife Winnie. His boat, the Zeeman Challenger, is a seven-metre custom plywood vessel.
Tuijn has overcome a variety of obstacles to reach the halfway point. He is suffering from the constant attention of sharks, who often bump his boat and disrupt his attempts at sleep. One particular shark, dubbed ‘Gomulka’ by Tuijn, has been trailing the adventurer’s boat for extended periods.
He has also accidentally burnt himself when he spilled hot water on his foot whilst trying to make coffee, apparently also from a shark ‘bump’. He is also forced to manually pump water for cooking and drinking after his automatic water pump broke down not long into his journey.
| “Physically everything feels great and I can’t help feeling that I could do this for 500 days, but mentally it’s still hard to be on your own for such a long time” | ||
His vessel has no motors or sails, but relies on his physical rowing power to move. The boat does have a solar power system to provide energy for his laptop, a telephone and a global positioning system.
Tujin, who is raising money for a children’s home in Mumbai, India, is rowing at an average speed of 58 kilometres each day. His diet consists of freeze-dried foods and fish, which are keeping him physically well-conditioned despite tiring mentally.
Tuijn is a serial adventurer and experienced rower. He has rowed across the Atlantic Ocean and the North Sea, as well as cycled across Russia and the icy terrain of Greenland.

An Australian has been shot in the abdomen in Thailand. The 22-year-old man from Wagga Wagga, Lee Burkinshaw, was shot in the Chantaburi province during a drive by shooting. He was evacuated to Bangkok hospital after receiving some treatment at a local hospital. An operation is needed to remove the bullet from his abdomen. He is expected to make a full recovery.
His spleen was removed but no vital organs have been damaged.
His father received a call at 2 a.m. AEST.
Lee went to Thailand to study the gem cutting.
“It is the gem capital of the world, and a lot of the rough cut gemstones come into there to be cut and styled,” Mr. Burkingsaw said.
He is undeterred from revisiting Thailand.
“This is purely a one-off incident … Thailand is a wonderful country, it’s just an unfortunate incident,” said Lee.
This is the second incident in recent weeks in which an Australian had been shot in Thailand. Last week a nurse was killed when she was shot in the neck near a bar.
Sunday, February 13, 2005Cordon-bleu chef Homaru Cantu has announced a technique which allows him to create dishes made of edible, inkjet printed paper. Cantu, a head chef at the Moto restaurant in Chicago, has modified an ink-jet printer with the help of computer specialists from local firm Deep Labs and loaded it with cartridges containing concoctions of fruit and vegetables. Using this modified printer Cantu then prints onto edible sheets of soybean and potato starch tasty images downloaded from the web.
“You can make an ink-jet printer do just about anything,” says Cantu. Once the items have been printed they are dipped into a powder made of soy sauce, sugar and vegetables before then being further processed by frying, freezing, or baking them.
Cantu has applied the technique to the printing of menus so that diners can further flavor their soups by ripping up the menu and adding it to the dish.
He hopes that his idea may find its way into popular media. “Just imagine going through a magazine and looking at an ad for pizza. You wonder what it tastes like, so you rip a page out and eat it,” says the chef who is working at perfecting the flavors and has applied for a patent on the technique.
Cantu also has plans for further culinary innovations. He plans to cook steak using a handheld laser that will sear the inside of the steak well done whilst leaving the outside medium rare. He also plans to use the laser to produce bread baked from the inside out thus producing a crust on the inside.

JetBlue Flight 292, en route to New York’s JFK Airport from Burbank, California, encountered nose gear malfunctions shortly after takeoff. It safely landed three hours later at Los Angeles International Airport (LAX) with no apparent injuries.
The pilots first realized something was wrong when the landing gear failed to retract; television footage showed that the plane’s front wheels were pointing sideways, perpendicular to the plane’s body. The plane was diverted to Long Beach Airport, where it tried and failed to land, and then on to LAX, which has better emergency facilities. The aircraft circled near the airport for several hours to burn fuel; the Airbus A320 aircraft is not designed to dump fuel.
Commentators predicted that the nose gear would either snap off, immediately twist to parallel upon touch down, or withstand the friction from the landing while remaining at a 90 degree angle.
At approximately 6:19PM local time, almost three hours after takeoff, the aircraft successfully managed to touch down. The pilot landed the plane first on its two rear wheels, keeping its nose in the air as long as possible until it slowed enough that the nose could be safely lowered. The front tires remained at a 90 degree angle and were incinerated through the friction. A cloud of white smoke and sparks burst out from behind the nose gear as the plane traveled down the runway. As the airplane finally stopped, the pilot had managed to keep the plane no more than 6 inches from the runway’s centerline. Officials were prepared with a brigade of fire engines as well as fire retardant foam in case the front wheel ignited. The plane was evacuated a few minutes later.
Reports indicate that the pilots acted in a “calm and professional manner.”
JetBlue flight 292 was in a unique situation as each seat in the plane was equipped with live TV through DirecTV. Several of the stations carried on the LiveTV system had cameras trained on the plane and were monitoring the situation. It has been established that the televisions were operating as the plane circled the airfield, though there are conflicting reports on whether or not the televisions were in operation during the landing. For a time, passengers on board were able to watch their own airplane circle the airfield in a precarious situation.
139 passengers and 6 crew were on board Flight 292.
