On April 27 in history: the opening of the item Dubna, completion of programmes of Apollo 16 and the first flight of the Airbus A380

April 27, 1970 American physical society organized a meeting, dedicated to the discovery of the chemical element number 105. The main task was the choice of the name to open, and the American community has adopted Gani – in honor of the German physicist Otto Hahn. The element was discovered during the work of albert Ghiorso in the radiation laboratory of the University of California at Berkeley. However, in the modern edition of the periodic table of Mendeleev element written as Dubna.

It turned out that around the same time, the element was independently opened in Dubna near Moscow. In the Soviet science city the item was received in a particle accelerator by bombarding 243Am nuclei 22Ne ions. Russian scientists have put forward the name of Dillsboro – in honor of Niels Bohr, but it was not approved finally. In 1993, the working group of the International Union of pure and applied chemistry (IUPAS) concluded that the honor of the opening element must be divided between groups from Berkeley and Dubna, and the final name became Dubna.
27 April 1972, the mission “Apollo 16 returned safely to Earth. It was the tenth manned mission in the framework of the program “Apollo” and the fifth landing men on the moon. The mission is intended purely scientific research, and for ease of movement available to the astronauts was the lunar Lunar Rover car, left there from a previous mission.

After completing the lunar program Lunar Rover remained on the moon
Main crew, consisting of three American astronauts: John young, Thomas Mattingly and Charles Duke, returned to earth in the module “Casper”. Splashdown took place in the Pacific ocean, 5.5 km from the estimated points and 5 kilometres from the search and rescue ship of the U.S. Navy.

It should be noted that the Apollo 16 was the penultimate flight in the framework of the lunar program and has set several records. So during the flight, was delivered a record (at the time) cargo to lunar orbit – 34 518 kg. it consisted of a detector of cosmic rays and ultraviolet camera. And on the last flight of the mission “Apollo” Apollo-1 belonged to the record of the longest stay on the lunar surface 71 hours 2 minutes) and the highest weight collected and delivered to Earth samples of lunar rocks (to 95.7 kg).
27 April 2005 the Airbus A380, the largest passenger plane in the world, made its first flight. Commercial operation began after two and a half years, October 25, 2007 on the route Singapore–Sydney. Actually, the first operator of the largest Airbus was Singapore Airlines. 18 Mar 2008 the first copy of the aircraft received the Australian Quantas, putting it on the route between Sydney and London.

Today the largest Explant A380 is Emirates, already have 77 planes and another 63 will be released in the future. Then there is Singapore Airlines, which has 19 instance A380, Lufthansa – Quantas 14 and – 12. None of the Russian flight company still has not placed orders for the A380.
We will remind, before the advent of the A380, the largest passenger aircraft remains the Boeing 747, which today competes with it. However, Singapore airlines has completely abandoned 474 in favor of the A380, but by the number of units produced Boeing in the lead by a wide margin – to date, produced more than a thousand copies of the Boeing 747 in different versions, while the A380 exists in the amount of 187 instances.
