Although some argue that life after 40 is only just beginning, it probably can not say the same for the popular poll of space, because all indications are that age gives her strongly felt.We remind you that Voyager 2 is an unmanned space probe sent into space in 1977 by the US space agency NASA’s Voyager program, whose aim was to explore Jupiter and Saturn systems. The probe quickly tackled with this task, so it was decided to extend the work of Uranus and Neptune. Later, she expanded exploration of the heliosphere and marginal areas beyond the heliopause to reach the local interstellar medium – the stage was held in November 2018, and then estimated how NASA had enough power for Voyager 2 2025. Could it was to prove that the estimates were somewhat inflated? It is difficult to judge clearly, but NASA just announced that there were some problems, due to which a probe passed into the security mode, and the engineers are doing what they can to eliminate them and restore the functioning of the Voyager. NASA says that Voyager 2 failed to perform the maneuver scheduled for January 25, which rotates 360 degrees to calibrate the instrument to measure the magnetic field. This means that the two systems with high energy cost worked at the same time, which exhausted the available energy resources.And that place, away 18.5 billion kilometers, you can not just send experts, the probe is designed so that in case of trouble to go to low power consumption mode, to protect against damage. Engineers are currently engaged in so communication with the probe to find out what happened – only that everything is very slow, because the signal reaches the probe in 17 hours, and as many takes to get answers. Either way, specialists are working on the problem and how we learned on January 28 was able to turn off one of these high energy cost systems, allowing for the inclusion of part of the scientific instruments. Engineers now analyze the data collected to check the status of the probe and turn off the other systems that Voyager 2 could return to normal operation. Will it work? It’s hard to say, but we must be prepared for the fact that this was the last gasp of historical probe.
Owned by BMW, the British company involved in the production of luxury cars, he shared what his new plans, which assume going in nuclear energy and the construction of several nuclear Minipower.In an interview with BBC Radio 4’s technological head of Rolls-Royce, Paul Sterin, announced that the company leads a consortium, the aim of which is to produce the factory modular nuclear reactors supplied to the construction site by a traditional truck. The company therefore build on the UK nuclear Minipower 15, the first of which is to start work already for nine years. There’s no denying that it fits well in the global trend of nuclear energy, because it is worth noting that currently operates 448 worldwide civil nuclear power plants, and another 53 had just built.And of course there are the opponents of this solution, which often falls as an argument in political disputes, but what’s interesting is increasingly comes not about the safety of this source of energy, but the high cost of power plant construction. This is where the action includes Rolls-Royce, which claims that the situation can be changed by the development of small reactors, mass produced in factories that you can bring to the place of conventional trucks, then fold in order to secure access to cheap electricity free of carbon.Of course, this method has its drawbacks, but the company believes that its consortium everything well planned and policzyło that with 15 mentioned reactors modular Small Modular Reactors (SMR) will bring the British economy 52 billion pounds, another 250 billion pounds in exports and over 40 thousand new jobs, all before 2050. Each station is designed to work 60 years and generate 440 MW of electricity, or enough to power the city the size of Leeds. The estimated cost of the generated electricity is 78 US dollars per MWh. According to Paul Stein: – Our goal is to release this energy into circulation in 2029. The ideal places to place our reactors are, where they still rely on outdated or decommissioned nuclear power plants. There are two places in Wales and one in the north-west of England. Ultimately, we want to have in the UK 10-15 such reactors. We also count on the strong interest in export, because it can be a huge industry. As we read in the press release, the idea will finance the British government, which has promised 18 million pounds.
It seems that this fabulous land inhabited not only huge parrot with a height of 1 meter and weighing up to 7 kg, which we learned recently, but penguins and huge, equaling growth of man.Set of bones found by an amateur paleontologist last year in the greensand Waipara was just belong to an entirely new species of bird, and more specifically the giant penguin, which reached up to 1.6 meters tall and 80 kg weight! What’s interesting, however, a new species, named Crossvallia waiparensis is not the first big penguin found in New Zealand, so scientists are of the opinion that all the penguins at a very early stage of its evolution, ie. Some 66-56 million years ago, were simply giants. Crossvallia waiparensis is one of the oldest known to us penguins and a great example of how many species of animals, especially living on the islands, after the extinction of dinosaurs shone in the unlikely environmental niches. According to the researchers C.waiparensis is closely related to other giant penguin, Crossvallia unienwillia, who long ago lived in Antarctica, where in 2000 his remains were found – indicates not only that once New Zealand and Antarctica were connected, but as both very changed. How to claim: – When veins Crossvallia species, New Zealand and Antarctica were much different than now – Antarctica was covered with forest, and both were much warmer than today. It should also be noted that although C.waiparensis was very large penguin when it comes to this stage, is firmly behind its modern relatives. Leg bones indicate that he used to swim in the foot more than the current penguins, may not be able to achieve a more upright position and engage their wings.Scientists also believe that it is not only new species discovered in Waipara greensand and are convinced that among the accumulated debris is more exotic cases that are just waiting to describe. Researchers have in fact hope that these will help us to better understand the process of hiding many mysteries of evolution penguins. If you want to see the remains of the giant C waiparensis own eyes, it’s the end of the year, they can be seen Canterbury Museum.
