Scientists Discuss Interstellar Space Mission

Scientists Discuss Interstellar Space Mission 86

A space probe designed to venture into the interstellar void could launch within as little as ten years.

To date only two spacecraft have ever gone beyond the confines of our solar system – Voyager 1 and Voyager 2 – a pair of historic probes that have been traveling now for over four decades.

While these ageing machines have already taught us more than anyone could have hoped for, their functionality is now very limited and it remains unclear how long they will continue to operate.

Most spacecraft are not designed to run for decades and neither of the Voyager probes were built with long-term interstellar travel in mind – their original objective was to explore the gas giants.

But what if we could build a probe specifically designed to leave the solar system ?

During this year’s International Astronautical Congress on October 25th, scientists discussed how such an adventurous undertaking could be achieved using today’s technology.

To reach the necessary speeds, the spacecraft would need to perform multiple planetary flybys.

Its goal would be to study interstellar space, investigate Kuiper Belt objects beyond the orbit of Neptune and to examine our solar system as a singular entity from far, far away.

It would be mankind’s first dedicated venture into the depths of interstellar space.

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 93

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!

A giant asteroid worth $ 17.4 billion is approaching Earth

A giant asteroid worth $ 17.4 billion is approaching Earth 95

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.

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 96

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.
