A giant asteroid worth $ 17.4 billion is approaching Earth

A giant asteroid worth $ 17.4 billion is approaching Earth 86

NASA announced the imminent flight of a potentially dangerous asteroid will pass the Earth. The website of the Center for the Study of Near-Earth Objects says that a celestial body ranging in size from 370 to 820 meters will approach the planet on November 29.

The asteroid, consisting of nickel, iron and cobalt, is approaching the Earth. The cost of minerals in its composition reaches $ 17.4 billion, with reference to the Asterank database, which contains data on 600 thousand asteroids.

The distance between the asteroid 153201 (2000 WO107) and the Earth will be more than 4 million kilometers, the Space Reference specified with reference to NASA data. It is noted that the distance from the Earth to the Moon is 10 times less, and the asteroid is considered dangerous because it crosses the orbit of our planet.

According to the NASA Center for the Study of Near-Earth Objects, the celestial body will approach the Earth on November 29. 

It is noted that this time the asteroid does not pose a threat to the planet, however, it belongs to the group of potentially dangerous ones, since its trajectory crosses the Earth’s orbit.

In 2021, the Moon will host a car race driven by schoolchildren

In 2021, the Moon will host a car race driven by schoolchildren 87
MAPP project

In 2021, a remote controlled rover race will take place on the lunar surface. At the same time, the development of these cars will be carried out by the famous auto designer Frank Stephenson, who worked with BMW, Ferrari and other whales of the automotive business, and … schoolchildren. Such an amazing statement was made by representatives of the Moon Mark project.

On October 11, 2021, the launch of the Nova-C device, developed by Intuitive Machines, is planned. This probe is slated to land softly on the surface of Selene in the Ocean of Storms.

If successful, it will be the first soft-landing probe designed and manufactured by a private company (not with private money, though).

Nova-C is capable of delivering up to one hundred kilograms of payload to the moon. Most of it is NASA’s scientific instruments, which funded the project. By the way, NASA allocated $ 77 million for the creation and launch of the spacecraft . However, the contract stipulates a certain payload limit, which Intuitive Machines has the right to spend at its discretion.

And eight kilograms of this limit will be allocated to … racing rovers from the Moon Mark company. Each vehicle will weigh 2.5 kilograms, and another three kilograms will be a system for deploying them on the surface of Selena.

This is a very extravagant decision (although how is it worse than sending a car on an interplanetary trip by Elon Musk ?).

Recall that over the past 40 years there have been only five attempts at soft landing on the moon. Of these, two ( Israeli and Indian ) ended in failure. And now it turns out that 8% of the space on the device flying to Selena (and the cost of this 8%, based on the project budget, will amount to more than $ 6 million) will be spent on entertainment for children.

In this place, any scientist who for decades dreamed of delivering his device to the moon for certain scientific research could start banging his head against the wall.

But the project developers have their own reasons. The race will attract the attention of society to space exploration, and above all of the younger generation. But these are future astronomers, engineers, entrepreneurs, and also voters and even politicians. If today’s children light up with the dream of exploring the Universe, and then carry it into their hearts into their adult life, then this $ 6,000,000 (by the way, not such a large amount by the standards of modern astronautics) will turn out not to be a reckless waste, but a very profitable investment in the future of humanity.

What will this project look like in practice? The lunar surface races will be the main prize of the Moon Mark’s Mission 1 competition, which will feature six teams of high school students. Schoolchildren will compete in drone races, space mission design and other fun things.

The two winning teams will receive the right to operate the racing moon rovers (from Earth, of course). But first, they will take part in their development. The chassis, controls and other important systems will of course be designed by specialists.

It is known for certain that the schoolchildren will work out the body design (here the famous Frank Stevenson will help them). This is also not an easy task. After all, the body must protect the device from damage in accidents and save it from the ubiquitous moon dust. In addition, when designing it, the mass distribution and many other technical parameters must be taken into account.

The prototype of the racing lunar rovers will be the MAPP project from the Lunar Outpost company (it is covered in more detail in the video below). True, the concept will have to be finalized, because the MAPP devices weigh 10 kilograms and move at a speed of only 360 meters per hour, which is by no means dizzying.

Note that the actual pace of the races is a separate issue. The speed of future rovers has not yet been announced. However, the radio signal takes 1.3 seconds to reach the moon and the same time to return. It is unlikely that this way you can control something really fast in real time.

The route of future races is also yet to be laid.

“There is a trail that designs Hermann Tilke, who designed all the latest track,” Formula 1 “around the world” – says Stevenson material New Atlas.

Of course, the path will not be marked in any way on the lunar surface. Perhaps the route will be shown as a line on the screens where young operators will follow the movement of their vehicles.

In any case, the feast of technical thought will not be long. The Nova-C device is not equipped with heaters, which means that the life of its entire payload is one lunar day (about two Earth weeks).

In December, Earth’s inhabitants will be able to see a rare cosmic phenomenon

In December, Earth's inhabitants will be able to see a rare cosmic phenomenon 89

At the end of the year, astronomers expect to see a rare cosmic phenomenon dubbed the “Christmas star” in the sky. It will be caused by the fact that Saturn and Jupiter come close to each other at a minimum distance and almost collide to become one super-bright point of light.

These two planets became one straight line in the solar system a few weeks ago, but at the end of December they will be on it for observers from Earth. This will happen on December 21, 2020, on the day of the winter solstice, when the daylight hours are the shortest and the night is the longest. Jupiter and Saturn will look like a “double planet” for the first time since the Middle Ages, Forbes writes.

“The conjunctions of the two planets are extremely rare, but this particular conjunction is especially rare because the planets will be very close to each other,” Patrick Hartigan, astronomer at Rice University, USA said. “In order to observe a closer conjunction of these planets in the night sky, we would have to return on March 4, 1226.”

It is noted that the unusual celestial phenomenon can be observed from anywhere on the planet. The main thing is that the sky is clear. The “Christmas Star” can be seen in the western sky about an hour after sunset when viewed from the northern hemisphere.

“On the evening of their closest approach, December 21, they will appear as a twin planet, separated by less than 1/5 the diameter of the full moon,” Hartigan said. “For most amateur astronomers looking at the night sky through a telescope, both planets and several of their largest satellites will be in the same field of view this evening.”

Those who want to see Jupiter and Saturn converge in the sky as close, but will be higher above the horizon, will have to wait until March 15, 2080, Hartigan said. After that, a similar configuration for this planetary pair will not be observed until 2400.

Astronomers are already preparing equipment to analyze in detail the upcoming event. Everything is very serious, because the second such rapprochement between Jupiter and Saturn cannot be expected.

Of course, there will not be a collision of planets. You just get the impression that something terrible is about to happen in the solar system. Astronomers have assured that there is no reason to worry.

Is the “Christmas Star” an omen of things to come? Mark your calendars!

Intrusive buzzing. The Perseverance rover recorded the space sounds of its flight to Mars

Intrusive buzzing. The Perseverance rover recorded the space sounds of its flight to Mars 91

NASA’s new rover is equipped with a microphone to record sounds during landing on the Red Planet.

NASA’s Perseverance rover, which is en route to Mars, has recorded its flight to the planet.

The new rover is equipped with a microphone designed to record sound when entering the atmosphere, descent and landing. The device should arrive on the Red Planet in February 2021.

But before the rover reached its destination, NASA’s Jet Propulsion Laboratory (JPL) released an audio file recording what the rover “hears” during its interplanetary voyage.

The 60-second recording, posted on SoundCloud, was captured on Oct.19 while checking the rover’s EDL and microphone system.

Experts explain that the buzzing sound comes from a pump that pumps fluid to regulate the rover’s temperature.

NASA compares the new hit for your playlist to the noise you hear on wired headphones when the wire rubs against your clothing. It was these mechanical vibrations that the Perseverance microphone picked up.

“Located at the rear of the starboard side of the Perseverance, the pump is part of the unit’s heat system that maintains operating temperatures for the equipment, even in the coldest locations,” JPL said in a statement.

“I apologize to the person who came up with the slogan for the film” Alien “(” No one in space will hear your scream “- ed.), Perhaps no one will hear the scream, but perhaps a pump to remove heat will be heard,” says a leading engineer at JPL Dave Gruel.

He added that the microphone picks up the hum of the pump through mechanical vibration.

The Perseverance rover is supposed to land on Mars on February 18, 2021 in the Jezero crater – it is believed that a riverbed used to pass through this area. This is one of those places where traces of living organisms on the planet could be preserved.

The main mission of the rover is to detect signs of life in order to advance the study of the ancient history of Mars. In addition, the device will become part of a mission to deliver samples from the surface of the red planet: it will dig out rock at certain points, and then another device will pick them up, which will send them to Earth.
