The Cassini spacecraft has found features that look like methane lakes in the northern latitudes of Titan (see JPL press release). The large dark patches, some about 30 miles across with rounded edges, appear to be associated with fluid channels. Radar echoes cannot determine for sure whether the surface is liquid (dark means smooth, light means rough); the dark features could represent dry lakebeds like those found by the Huygens Probe. Still, the surfaces appear extremely flat, although some of them may show evidence of waves. Since these large, rounded dark features did not appear at equatorial latitudes, a comparison with the south pole at a future flyby will be instructive. The radar images were obtained during the T16 flyby on Saturday, July 22. Amateur enthusiasts are abuzz with excitement and interpretations at Unmanned Spaceflight, and Emily at the Planetary Society is sure they are lakes, comparing them to other lakes in the solar system. They could be calderas from cryovolcanism – or just remnants of long-gone lakes. A report on Science Now says the dark areas show higher temperatures, as would be expected from liquids, and reside north of 70° where methane rains would more likely occur. Another Titan story comes from the European Space Agency. By analyzing interference patterns in the radio signal from the Huygens probe to the Cassini orbiter, researchers calculated that the surface the probe landed on is covered with pebbles 5-10cm in diameter. Also from the Saturn system, another view of Enceladus was released, paired with the moon Rhea. Taken from 2.5 million miles away, the jets of Enceladus (en-SELL-a-dus) are clearly visible (see 07/11/2006 story). A processed image was released July 21 allowing details of the outer plume to be shown feeding the E-ring. The next close flyby won’t be till March 12, 2008 near the end of the prime mission (see timeline). Since Enceladus has proven extraordinarily interesting, it will doubtless become a prime target for any extended mission if the spacecraft continues its nine-year record of good health. Heads Down: Cassini is now increasing its inclination over the next few orbits (plot, the 180-degree transfer). By fall through spring, we should get unprecedented views looking down over Saturn’s rings from high overhead. This will provide a welcome change of view after months of seeing the rings as thin lines (example). The edge-on views have reminded us that, for all their vast extent, the rings are only about 100m thick. The new vantage point, showing the ring system’s full breadth and detail of color and structure (example) is sure to inspire artists and poets as well as scientists (see overhead diagram).Titan appears to be showing a distinct regional difference between the equator and the poles. Being cooler, the poles may be condensing out more of the liquid methane and ethane that is believed to be constantly produced in the upper atmosphere. The current radar SAR image strip represents only a tiny fraction of Titan’s surface, so it is impossible to say if this region with its dark patches represents much of the polar regions or not. The last two radar passes have been exceptionally intriguing (see also the July 19 press release about the April 30 flyby). Titan presents a few familiar landscapes, but many unique ones. Impact craters are rare, and there are no high mountains (as detected on the smaller moons like Iapetus). It’s going to take awhile to sort all this out. Too much theorizing too early might spoil the fun of discovery.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
US President Donald Trump. THE US airline industry has urged President-elect Donald Trump to make the nation’s air traffic control a priority as part of any plan to boost infrastructure.It remains unclear what aviation policies, if any, the private aircraft operator and former owner of the failed Trump Shuttle has up his sleeve.But that didn’t stop airline lobby groups from moving quickly to establish a position in the wake of his protectionist campaign and his comments about boosting American industry.In a congratulatory statement, industry lobbyist A4A noted comments in the billionaire’s acceptance speech and during his campaign that a $US1 trillion plan to improve infrastructure would by priority in the first 100 days.“We look forward to working with the Transition Team on strengthening our infrastructure in the sky to meet the nation’s growing demands on the ground,” said A4A chief executive Nicholas E. Calio. “The current U.S. Air Traffic Control system, while safe, is an inefficient relic of the 1940s.“We’re eager to work with President-elect Trump to transform it to reduce delays for the 2.2 million passengers and 50,000 tons of cargo that fly every day, while accommodating future growth and demand for travel and shipping.”A4A estimates the US airline industry supports 10 million jobs and drives 5 percent of the total U.S. economy each day.“Our ability to create more jobs and help fuel economic growth is possible only if we’re operating within a National Airspace (NAS) infrastructure that is designed for the future,” Calio said. “Our vision for a modernized NAS includes reforming the Air Traffic Control (ATC).“A service provided under appropriate authority to promote the safe, orderly and expeditious flow of air system so that politics don’t impede hiring and training more air traffic controllers and equipping our facilities with technology used by more than 50 countries around the world.“We want to see a reliable ATC funding model – funded by the system users, not political gamesmanship – so that we can plan for the long-term capital improvements the system needs to grow.”Air Traffic control improvements are not the only issue about which US airlines will be lobbying: passenger rights regulations and access by foreign carriers are also on the agenda.The “big three”’ — Delta Air Lines, American Airlines and United Airlines — have been conducting a running battle with Gulf carriers with allegations of billions of dollars of unfair subsidies. Gulf airlines Emirates, Etihad and Qatar has rejected the allegations and launched counter accusations that US airlines were protected by the Chapter 11 bankruptcy process.A lobby group formed by the US carriers and labor unions, the Partnership for Fair and Open Skies, has quickly seized on Trump’s rhetoric about protecting US industry against unfair competition.“We look forward to briefing President-elect Donald Trump and his new administration on the massive, unfair subsidies that the UAE and Qatar give to their state-owned Gulf carriers,” spokeswoman Jill Zuckman said in a statement. “The Gulf carrier subsidies threaten the jobs of 300,000 U.S. aviation workers and the American aviation industry as a whole, and we are optimistic that the Trump administration will stand up to the UAE and Qatar, enforce our trade agreements and fight for American jobs.”However, an analysis by the CAPA Centre for Aviation warned that a move toward greater protectionism could hurt US carriers.It estimated the abandonment of the Trans-Pacific Trade Partnership Agreement could see the industry forgo new route developments and 5 to 10 per cent in traffic growth the trade deal would have otherwise have generated.And it cautioned that the already clouded open skies issue could “darken further’’ if a Trump administration accepts the premise that open skies have passed their zenith.“Aviation policy typically does not feature high in the priorities of prospective Presidential candidates,’’ it said “” Yet the nationalistic appeal of the airline pilots’ unions struck a chord with both populist candidates – both Mr Trump’s and Mr (Democratic contender Bernie) Sanders’ campaigns expressly attacked Norwegian Airlines International’s moves to operate into the US.“The often-misplaced arguments fell squarely into the category of appealing to voters concerned for their jobs, and who see all the perceived negatives of foreign trade – without recognising the positives.“For US airlines and the US industry generally this is dangerous territory as it is the US airlines who have – at least in the medium term – the most to gain from liberal market access. The likely overall outcome: slower growth and less foreign airline competition.’’CAPA also warned that Trump’s aggressive stance against China could undermine the ability of US airlines to capitalise on one of the world’s biggest aviation markets and said “shotgun effect” of proposed visa restrictions could not avoid affecting air traffic, particularly from Mexico.

We have to stick together and show great commitment and desire.“The players didn’t let me down today, they tried everything and gave their heart. We just weren’t effective enough in using our chances. Carrow Road will be a fortress again next week. We have to go through this difficult time together.”He added: “There were some crucial periods in the game. We had to stand strong in the first 15 minutes and not allow them to have many chances. There was no need to concede the penalty because the striker was facing away from our goal. We have to be a bit more calm.”

Paul Scholes has revealed that Manchester United’s performances are making it difficult for him to watch his former club playUnited once again failed to win any of their last 4 games across all competitions and are struggling to win a home fixture since their triumph over Leicester City.However, Red Devil’s legend Paul Scholes went further to suggest the Old Trafford outfit are no longer an exciting side to watch.“We talk about them being dull and we talk about the first 10 games (of this season), but you go into last season as well,” he said.“It’s been dull to watch. I don’t know how many times we’ve sat in the studio watching games and we end up watching the other screens looking at the other games to find some goals. That’s just the way it is.“But they’re still in a strong position in the group, they’ll still go through the group. But hopefully, that Juventus game (the next one in the group) will liven it up a bit.”Mourinho: “Lionel Messi made me a better coach” Andrew Smyth – September 14, 2019 Jose Mourinho believes the experience of going up against Barcelona superstar Lionel Messi at Real Madrid made him a greater coach.Before the match, Scholes was critical of Mourinho’s tactics for the defeat at West Ham on Saturday.“I’m surprised he survived after Saturday,” he said.“The performance was that bad. The attitude and performance were nowhere near.“He’s coming out in press conference, he is constantly having a go at players, he’s having a go at people above him because he is not getting what he wants.“I think his mouth is probably out of control and I think he’s embarrassing the club.”
Barcelona boss Ernesto Valverde doesn’t seem convinced by the possibility of his side bringing Neymar back to Camp Nou anytime soon.The 26-year-old Brazilian part company with the Catalans last year to join Paris Saint-Germain in a world-record busting transfer just when Valverde took charge of the team.The Parisians had to splash out a staggering €222 million to secure the services of tricky forward, who at the time wanted to escape Leo Messi’s shadow.However, it seems that Neymar’s fortune let him down again, as he now finds himself in a shadow of Kylian Mbappe, the most talented youngster on the planet.Therefore, the ex-Santos star would like to leave Parc des Princes, and it appears that PSG president Nasser Al-Khelaifi has put a release clause in his contract, which will become active in the summer of 2020.According to the Spanish news outlet, Marca, Valverde is still skeptical about Blaugrana’s chances of landing the former talisman in the forthcoming period.Quiz: How much do you know about David Villa? Boro Tanchev – September 14, 2019 Time to test your knowledge about Spanish legendary forward David Villa.“I coached him for 15 days.“Any time of the season is a good one to ask these questions but Neymar is at another team, it’s all speculation.“We aren’t in the market to sign players.“It’s a good topic for speculation, but we don’t know what could happen.“It’s difficult, I don’t know… We’ll see.”As things stand, in case the current La Liga holders decide to rehire Neymar, they would have to allocate nothing less than £190 million to make the deal go through.
After a positive season such as Tottenham’s 2017/18 campaign, Pochettino explains that the determination to be better is paramount.The 46-year old Tottenham manager insists that working hard together as a squad is very important as they hope to produce the same result as they did in last season.“Across all areas, we need to improve [at Tottenham],” Pochettino says via Skysports.“It’s a very powerful thing to keep all the squad together but at the same time you need to understand that the power is only important if you are clever and use that power to push harder, work harder and to be better.Pochettino: ‘Happy’ Christian Eriksen ready for Spurs action Andrew Smyth – September 12, 2019 Mauricio Pochettino insists Christian Eriksen is “happy” and in the right frame of mind for Tottenham despite his failed summer exit.“When you add new players and some players leave, it is easy to refresh the squad and to have a different challenge.“Because last season we were good or the World Cup was good, we are going to repeat the same this season? It’s not like this in football. You always need to try to improve and that is the challenge that we need the players to realise: they need to work harder than last season.“Of course, there are the different circumstances and the World Cup and the pre-season was completely different. But that makes us as coaches think and provide the best tools to them to keep them performing in the way we need to win games.”
