NASA is planning a mission to a massive metallic asteroid valued at 7,700 quadrillion pounds ($ 10,000 quadrillion). The diameter of the asteroid, called 16 Psyche, About 140 miles, and it’s one of the most massive objects in the main asteroid belt orbiting between Mars and Jupiter.

Dr. Tracy Baker, planetary researcher at the Southwest Research Institute, said, “We have seen meteorites, most of them metal, but 16 Psyche It might be unique in that it is an asteroid made entirely of iron and nickel in that planet Earth is a metal core, cap, and crust and it is possible that during the formation of a first planet with one another object collided in our solar system and lost its mantle and shell.

Experts predict that iron alone accounts for 16% Psyche It could be worth $ 10,000 quadrillion – if it could be brought to earth for comparison, the global economy was valued at $ 80,934,771,028,340 (£ 62,388,972,921,051.02) in 2017.

This means the asteroid could be worth 123,556.29 times the economy Global news In 2017 she said Lindy Elkins-Tanton NASA mission senior scientist and director of the College of Earth and Space Exploration at Arizona State University: “Even if we could take a big coin and move back here, what would you do?” Could you sit down and hide it and the Control global resources as diamonds are institutionally controlled – and protect your market? What if you decide to return it one more time and solve mankind’s mineral resource problems at any time? It is clear that this is wild speculation.

NASA plans to visit the asteroid in 2022 in hopes of understanding how terrestrial planets like Earth first formed.

The spacecraft is scheduled to launch in 2022 before it reaches orbit Psyche In 2026, to orbit the asteroid for 21 months, map and study properties PsycheBefore they send their results back to Earth.

And NASA stated, “In the depths of the rocky and terrestrial planets – including the Earth – scientists infer the presence of metal cores, but these are far fetched under the rocky crusts of the planets and since we cannot see the heart of the planets Earth or measure it directly, Psyche It provides a unique window into the violent history of collisions and agglomerations that created the planets of the earth. ”

Watch unreal drone footage of Arecibo Observatory's catastrophic collapse – CNET

Published

 on


The National Science Foundation released stunning video footage Thursday capturing the exact dramatic moment the Arecibo Observatory’s 900-ton platform fell into the 1,000-foot wide dish below. A drone happened to be performing an up-close investigation of the cables that still held the platform above the dish as the cables snapped on Tuesday.

The video of the massive radio telescope shows both the drone footage and the view from a camera in the visitor center that shows the platform falling into the dish just above the jungle floor in Arecibo, Puerto Rico. Two massive chunks of the cement towers that the cables were attached to can also be seen falling.

Two of the cables had previously broken, one in August and another in November, destabilizing the telescope.

A drone was inspecting the site atop one of the towers, where one of the previous cable breaks had occurred, when the rest suddenly snapped. 

The NSF had recently decided to decommission the telescope after a second cable broke in November.

“It was a dangerous situation,” John Abruzzo, who is with an engineering consulting firm called Thornton Tomasetti that was contracted by the NSF, told reporters Thursday. “Those cables could have failed at any time.” 

On Tuesday, they did.

The NSF reports that no one was injured in the collapse and that the visitor center sustained only minor damage.

The telescope, which functioned for nearly 60 years, was the backdrop to a dramatic fight scene in the 1995 James Bond movie GoldenEye with Pierce Brosnan. It also appeared in the 1997 Jodie Foster movie Contact. But Arecibo’s true legacy lies in the many scientific discoveries it made possible. It explored pulsars, expanded our knowledge of Mercury, spotted exoplanets and found fast radio bursts.

Unfurling China's flag on moon_china.org.cn – China.org.cn

The China National Space Administration Friday released images showing China’s national flag unfurled from the Chang’e-5 probe on the moon.

The images were taken by a panoramic camera installed on the lander-ascender combination of the probe, before the ascender blasted off from the moon with lunar samples late Thursday.

In one of the images, a robotic arm to collect lunar samples can be seen next to the flag.

On Dec. 15, 2013, color images showed the Chinese flag on the country’s first moon rover Yutu, the first time the five-star red flag had been pictured on an extraterrestrial body.

Unlike the flags in China’s previous lunar missions, the flag on Chang’e-5 was made of real fabric, rather than a spray coating. Chinese engineers and technicians revealed the advanced engineering behind the special flag.

A flag made from traditional fabrics would most likely lose color and disintegrate in the harsh lunar environment of abrasive dust, unfiltered cosmic rays and solar flares.

The flag must also be as light and compact as possible, as the spacecraft has very little room for anything more than scientific equipment.

Last but not least, how to make the flag stay perfect en route to the moon and look good on camera?

The flag team from China Aerospace Science and Industry Corporation Ltd. chose a scroll design, so the flag unfurls smooth and flat and not wrinkled and drooping.

It took them more than a year to find a new composite material that could stand the harsh environment and be dyed in China’s vivid national colors. After being rolled up, the fabric will not stick together in temperatures ranging from 150 degrees Celsius to 150 degrees below zero. The flag made from the fabric only weighs 12 grams.

Li Yunfeng, director of the flag system, said the flag system used a mechanical structure that has been applied to the unfolding of solar panels on satellites and spacecrafts. The structure also makes the system weighing no more than 1 kg.

At the top is a hollow ball structure to fix the flag. Engineer Huang Min and lathe operator Liao Guangheng were inspired by Gashapon capsule toys in making it so light.

A flag represents the dignity and honor of a country, said Huang and Liao: “We have to make sure it’s spotless and infallible.”

A detonator unfurls the flag. To make sure it unfurled in one second sharp, the team simulated the lunar environment with a massive temperature difference between day and night, and carried out dozens of tests.

Liu Haigang, a veteran milling machine operator, said the parts he was responsible for were the most difficult challenge of his career.

He said he felt so proud when he finally put the finished pieces in the box as it was like looking at a work of art.

“When it lands on the moon, I’ll tell my grandson ‘Grandpa made this’.”

China’s Chang’e-5 probe was launched on Nov. 24, and its lander-ascender combination touched down on the north of the Mons Rumker in Oceanus Procellarum, also known as the Ocean of Storms, on the near side of the moon on Dec. 1.

After the samples were collected and sealed, the ascender of Chang’e-5 took off from the lunar surface late Thursday, and is expected to carry out unmanned rendezvous and docking with the orbiter-returner in lunar orbit, an unprecedented feat.

Chang’e-5 is one of the most complicated and challenging missions in Chinese aerospace history, as well as the world’s first moon-sample mission in more than 40 years.

Chinese Chang'e-5 Is Returning From Moon With Rocks, Left A Flag To Celebrate – KCCU

Published

 on


China’s lunar probe Chang’e-5 is on its way back to Earth after a brief visit to the moon Thursday. The craft collected soil and rock samples over the course of about 19 hours and then left the lunar surface.

The samples are expected to land on Earth around the middle of the month.

Before it left, the spacecraft planted a flag there — making China only the second country to leave its national banner on the moon. China hadn’t deployed one in two previous landings.

Getting a flag to the moon isn’t easy and solar radiation has likely bleached out the ones planted by U.S. astronauts, according to NASA.

For China, its most recent accomplishment has a nostalgic feel, aerospace expert and TV commentator Song Zhongping told China’s Global Times. It has been more than half a century since the NASA Apollo 11 crew walked on the moon.

“Yesterday’s memory is still fresh and clear, when the U.S. astronauts stepped outside their cabins and planted the first flag in human history, an American national flag, on the moon in 1969,” Zhongping said. “But China is about to showcase our own national flag as well, which I believe is a recognition of achievements and breakthroughs that we have made, which will be the most valuable thing.”

The Soviet Union was the first country to leave its mark on the moon, intentionally smashing the Luna 2 probe there in 1959.
