Output: An Italian court says it convicted Amanda Knox and her former boyfriend of murdering her onetime roommate in part because of evidence showing that more than one person killed the British student. The Florence appeals court released its explanation Tuesday, less than three months after it convicted Knox and Raffaele Sollecito in Meredith Kercher's 2007 death in a retrial. In the more than 300-page document, the court said that a third person convicted in the murder, Rudy Guede, did not act alone, and cited the nature of the victim's wounds. Ruling Judge Alessandro Nencini, who presided over the second appeal in the case, said Kercher, 21, and Knox disagreed over the payment of the rent in the house they shared in Perugia and that "there was an argument, then an elevation and progression of aggression." The Florence court in January said that Knox, who also was convicted of slander, was sentenced in absentia to 28Â½ years in prison. Sollecito's sentence was 25 years. They were first convicted of murder in 2009, but the verdicts were overturned on appeal in 2011. Through her attorney, Knox released a statement proclaiming her innocence. "I have stated from the beginning of this long ordeal that I am innocent of the accusations against me. I was found innocent by the only court in Italy that retained independent forensic experts to review my case. "I want to state again today what I have said throughout this process: I am innocent of the accusation against me, and the recent Motivation document does not -- and cannot -- change the fact of my innocence," she said. Now that the explanation of the verdict has been released, defense lawyers have 90 days to appeal to Italy's high court. In the document, Nencini focuses on the perceived errors of the appellate court that set Knox and Sollecito free, accusing it of the "absence of logic rigor" when evaluating evidence. He wrote that some evidence, including a prison diary Knox wrote in the early days of her incarceration, was used to support her innocence when it was "convenient, but at the same time devalued when she incriminated herself." The judge also reasoned that Knox's false accusation of her former boss, Patrick Lumumba, whom she accused of the killing the night she was arrested, proved her guilt. Lumumba spent nearly two weeks in prison without Knox correcting her false accusation. He was released when Guede was arrested after his fingerprints were found in at the murder scene. Nencini wrote that the accusation against Lumumba was "indispensable in understanding the crime" and that the accusation "cannot be separated from the murder." Nencini also considered credible forensic testimony that the first appellate court dismissed, including traces of mixed blood and DNA belonging to both Knox and Kercher that were identified in the bathroom that the women shared. "Guede, Knox and Sollecito left traces of their movements in the blood of the victim that was flowing profusely from her wounds," the judge wrote. Nencini excluded the idea that Guede climbed into the apartment through a window after breaking it with a rock as the Knox and Sollecito defense teams presented in earlier trials. He also excluded the idea put forth by Guede's defense that Kercher let him in for a prearranged meeting. Instead, he wrote: "The court accepts the position that only Amanda Knox was in possession of the other key to the apartment" and that she let him in. Nencini dismissed all theories related to a sex game gone wrong. Prosecutors had argued Kercher was stabbed to death after she rejected attempts by Knox, Sollecito and Guede to involve her in a sex game. Instead, Nencini wrote that the suspects did not need to "share a motive." He said a knife with Knox's DNA on the handle found in Sollecito's apartment was the weapon that killed Kercher and that Knox left her DNA on the handle when she "plunged the knife into the left side of Kercher's neck, causing the fatal wound." In the initial trial, a tiny spot of DNA identified on the blade of that knife was attributed to Kercher, but the sample was too small to double test. Nencini nonetheless considered it the primary weapon. He reasoned that Sollecito used another knife and took it with him when he left. "The English girl was attacked by Amanda Marie Knox, by Raffaele Sollecito, who was backing up his girlfriend, and by Rudy Hermann Guede," Nencini wrote. Guede is the only person in jail for the slaying, and many aspects of the crime remain unexplained. Knox and Sollecito have maintained their innocence, and their 2009 convictions led to questions about the effectiveness of Italy's justice system. The trial revealed widespread doubts over the handling of the investigation and key pieces of evidence. But in March 2013, Italy's Supreme Court overturned their acquittals and ordered a retrial. That proceeding resulted in the convictions being reinstated. Knox's conviction has raised questions about her possible extradition to Italy to serve her sentence; she was in the United States and did not attend the retrial.

assistant: Nass and MIT has given a spacecraft orbiting the moon a super high speed internet connection far faster than most users on Earth. The team admit they were stunned by the results, which pave to way for 3D video and remote robotic exploration of other moons and planets. The team say their groundbreaking test 'worked like gangbusters'. Scroll down for videos... ESA's Optical Ground Station (OGS), which houses the Lunar Lasercom Optical Ground System used in the experiment. The test, in October of last year, beamed data, via laser, at speeds reaching 622 megabits per second, to Earth from a spacecraft orbiting the moon. Radio-frequency systems used for space communications today are usually tens of times slower. 'It worked like gangbusters,' Don. Boroson, who led the LLCD design team at Lincoln Lab, and presented the. demo’s results at the SPIE Photonics West conference said. NASA and Lincoln Lab engineers tested the first-ever two-way laser link between the moon and the earth for about a month, according to Spectrum IEEE. 'The system did what it needed to do,' Boroson said. 'The concept is right, and the system is reliable. We think it’s ready for prime time.' NASA’s follow-up laser communication mission, the Laser Communication Relay Demonstration (LCRD), which is scheduled for launch in 2017, will attempt to establish laser links at a rate of over 1 gigabit per second between Earth and a satellite in geosynchronous orbit (which is ten times closer than the moon). Nasa is planning to ditch primitive radio transmissions and start communicating with lasers in space. The experiment is part of the Lunar Laser Communication Demonstration (LLCD) mission which will be hosted aboard  LADEE satellite (pictured) The LCRD will operate for five years in order to demonstrate the reliability of laser communication technology. As well as HD video it could, for instance, also allow humans to remotely control machines for tasks such as asteroid mining or building structures on the moon. LLCD is Nasa’s first dedicated system for two-way communication using laser instead of radio waves. ‘The goal of the LLCD experiment is to validate and build confidence in this technology so that future missions will consider using it,’ said Don Cornwell, LLCD manager. VIDEO: An overview of the LLCD mission. ‘We can even envision such a laser-based system enabling a robotic mission to an asteroid,’ he added. ‘It could have 3D, high-definition video signals transmitted to Earth providing essentially “telepresence” to a human controller on the ground.’ Since Nasa first ventured into space, radio frequency (RF) communication has been the communications platform used. But it is now reaching its limit as demand for more data capacity increases. According to Nasa, laser communication would be less likely to suffer from interference, another limitation of radio frequency (RF) signals. ‘LLCD is designed to send six times more data from the moon using a smaller transmitter with 25 per cent less power as compared to the equivalent state-of-the-art radio (RF) system,’ said Cornwell. A primary ground terminal at Nasa's White Sands Complex in New Mexico will receive and transmit signals. ‘Lasers are also more secure and less susceptible to interference and jamming.’ The LLCD experiment is hosted aboard Nasa’s LADEE: a 100-day robotic mission designed, built, integrated, tested and will be operated by Ames. The LADEE spacecraft will take 30 days to reach the moon because of its flight path. LLCD will begin operations shortly after arrival into lunar orbit and continue for 30 days afterward. LLCD’s main mission objective is to transmit hundreds of millions of bits of data per second from the moon to Earth. This is equivalent to transmitting more than 100 HD television channels simultaneously. LLCD receiving capability will also be tested as tens of millions of bits per second are sent from Earth to the spacecraft. An MIT team designed, built, and tested the terminal. They will be responsible for LLCD's operation at that site. There is a primary ground terminal at Nasa’s White Sands Complex in New Mexico, to receive and transmit LLCD signals. An MIT team designed, built, and tested the terminal. They also will be responsible for LLCD’s operation at that site. There are two alternate sites, one located at NASA’s Jet Propulsion Laboratory in California, which is for receiving only. The other is being provided by the European Space Agency on the Spanish island of Tenerife, off the coast of Africa. It will have two-way communication capability with LLCD. 'Having several sites gives us alternatives which greatly reduces the possibility of interference from clouds,' said Cornwell. Nasa engineers believe this technology is even more exciting for communications beyond Earth’s orbit. In the past, Nasa has experimented with sending low amounts of individual pulses to cameras on far-away space probes near Jupiter, Mars, and Mercury. Recently, an image of Leonardo da Vinci’s painting, the Mona Lisa, was transmitted to Nasa’s Lunar Reconnaissance Orbiter (LRO) spacecraft orbiting the moon. ‘But this was done at only hundreds of data bits per second,’ said Cornwell. ‘LLCD will be the first dedicated optical communication system and will send data millions of times faster.’
