China probe readies to land on dark side of the moon

China probe readies to land on dark side of the moon

The Chang'e 4 is very similar to the Chang'e 3, which was China's very first Moon landing success, and its successor is actually a backup version of the previous model that has been modified to carry out new mission objectives. Chang'e 4's lunar rover has been improved, engineers said, meaning it could work "for at least a few years on the moon". The moon's far side has a different composition than sites where missions have been conducted on the near side of the moon. Consulte Mais Informação

New Horizons set for historic flyby TOMORROW — NASA announcement

New Horizons is now operating on one extended mission for the Ultima Thule running through 2021 at a cost of $81 million. The close encounter comes 3½ years after the spacecraft swung past Pluto . "I was inspired by the idea that this is the furthest that the hand of man has ever reached, it will be by far the most distant object we have ever seen at close quarters, through the images which the space craft will beam back to Earth".

Trump EPA says limits on mercury emissions from coal plants not necessary

Trump EPA says limits on mercury emissions from coal plants not necessary

The 2011 Obama administration rule, called the Mercury and Air Toxics Standards , led to what electric utilities say was an $18 billion clean-up of mercury and other toxins from the smokestacks of coal-fired power plants. Mercury can cause brain damage, learning disabilities and birth defects in children, as well as problems for women during pregnancy. The EPA on Friday proposed a new rule that challenges the basis for the Obama regulation. Consulte Mais Informação

Cosmonaut Says ISS Hole Was Drilled From the Inside

Cosmonaut Says ISS Hole Was Drilled From the Inside

One of the unique things that the astronauts are doing is playing "Elf on the Shelf", the popular Christmas children's game that involves placing a small elf-like doll around your home - or for these astronauts - around the space station. They determined the source was a 2-millimeter hole in the Soyuz capsule and instantly filled it up with epoxy. The hole didn't pose a danger to Prokopyev and crewmates Serena Aunon-Chancellor of NASA and Alexander Gerst of the European Space Agency during ... Consulte Mais Informação

Japan’s resumption of commercial whaling may kill industry

Japan’s resumption of commercial whaling may kill industry

In 2014, the International Court of Justice ruled that Japan should halt its Antarctic whaling. "The government of Japan must urgently act to conserve marine ecosystems, rather than resume commercial whaling". Prior to this Japan hunted whales for "scientific research" - but also for the meat, a highly controversial practice. Japan suspended its hunt for one season to re-tool its whaling program with measures such as cutting the number of whales and species targeted, but resumed hunting in ... Consulte Mais Informação

Pluto explorer ushering in new year at more distant world

Flying beyond Pluto , the spacecraft will whish into the space streaming to the ancient relic of the solar system.

It's the first in a series and nicknamed Vespucci after the 15th-century Italian explorer who calculated Earth's circumference to within 80 kilometres. Consulte Mais Informação

Apollo 8 Astronauts Captured World's Attention In 1968 Moon Mission

Apollo 8 Astronauts Captured World's Attention In 1968 Moon Mission

Three-hundred-and-ninety-eight years later, on December 21, 1968, the three astronauts Frank Borman, James Lovell and William Anders entered Apollo's chariot. The mission may be best remembered for a photo that shows our planet as seen from the moon. And here came "Earthrise": a photo at once ideal and humanly imperfect - the tilted horizon, Earth slightly off-center, a rare moment of imprecision during a mission that relied on exact measurements from its military-trained astronauts.
