NASA's Curiosity rover lands on Mars
The Curiosity rover landed successfully on the surface of Mars, where for the next two years it will carry out investigations to discover if there was ever life on the Red Planet or whether there ever could be.
Word of "touchdown confirmed...we're safe on Mars" from engineer Allen Chen was greeted with cheers and hugs at the control room of the Jet Propulsion Laboratory of the National Aeronautics and Space Administration in Pasadena, California.
The 1-ton robotic device the size of a car reached Mars after traveling 567 million kilometers (352 million miles) in eight months and 17 days, and as it came in to land in the most frighteningly complex maneuver ever attempted with a planetary rover, NASA Associate Administrator for Science John Grunsfeld said that the "Seven Minutes of Terror has turned into the Seven Minutes of Triumph. My immense joy in the success of this mission is matched only by the overwhelming pride I feel for the women and men of the mission's team."

Mexican candidate says any deal must include new elections
There will be no negotiations with rival candidates because the only acceptable option is to invalidate Mexico's July 1 presidential election and hold a new vote, leftist candidate Andres Manuel Lopez Obrador said.
"There is only one agreement, the one that invalidates the presidential election, we are not going to allow any agreement that in any way that gets built over the swamp, over the filth, the main thing is to defend the votes of the citizens," Lopez Obrador told some 4,000 supporters at a rally Sunday in Puebla.
Lopez Obrador met with supporters in Puebla, located about 125 kilometers (77 miles) from Mexico City, and urged them to work with the 32 people's assemblies organized across the country to shed light on "electoral fraud."
A summary of the irregularities committed by the Institutional Revolutionary Party, or PRI, will be submitted to the TEPJF electoral court in the middle of this week, Lopez Obrador said.
Cuba reports 2nd offshore oil well came up dry
For the second time this year, exploratory drilling in Cuban waters of the Gulf of Mexico has failed to find oil and gas in commercially viable quantities, state-owned Cubapetroleo said.
The "active petroleum system" detected by Malaysia's PC Gulf and Russian firm Gazpromneft does not constitute a "commercial discovery," Cubapetroleo said in a statement published in the communist-ruled island's official media.
The effort was conducted at a depth of 4,666 meters (15,298 feet) in waters off the coast of the western province of Pinar del Rio, using the Scarabeo-9 rig.
An earlier foray with the same rig by Spanish oil company Repsol also produced disappointing results.
