Mission to Triton: the new and exciting destiny of NASA

Mission to Triton: the new and exciting destiny of NASA 86

Scientists believe that Triton, Neptune’s largest moon, could be an “aquatic world” with liquid water, and perhaps with alien life.

Exciting times are approaching as far as astronomy and knowledge of the universe are concerned. Soon we can enjoy new and revealing images of Triton.

NASA’s Jet Propulsion Laboratory proposed Tuesday at a conference in Texas to send a spacecraft named Trident to Triton, to investigate whether it harbors a docile or hostile habitat.

Instead of spending a billion dollars, Tridente aims to reduce costs for the American taxpayer, so that carrying out this mission involves an expense similar to what would be a routine mission to the Moon.

“Now is the time to do it at low cost,” said the director of the Houston Planetary and Lunar Institute and mission leader, Louise Prockter, during the Planetary and Lunar Science Conference that took place in Texas. “We will investigate and discover if Triton is a habitable world, which is of great importance . 

In addition to orbit Triton, Trident will also travel to the moon IO that orbits the giant Jupiter and is one of the most interesting moons of our solar system because of the adverse conditions it suffers from being so close to the planet.

During your trip through space, Trident will also pass through our neighbor Venus. This planet has not been visited since the Cassini spacecraft was literally squeezed by its atmosphere. Although Cassini was destroyed in a few seconds, it was able to send to NASA very relevant data on the conditions that occur there.

The last good image we got from Neptune was during a 1989 flyby of NASA’s Voyager 2, and it was also the first time a human-directed spacecraft visited this planet.

Thanks to Voyager 2 we discover immensity of data about our solar system and the bodies that orbit it.

Triton is 4500 million kilometers from the Sun. It is one of the coldest stars of the solar system (-235 ° C). and was discovered by William Lassell on October 10, 1846, only 17 days after Neptune’s own discovery.

It owes its name to the god Triton of ancient Greek mythology and has a diameter of 2,707 kilometers. Triton is the largest satellite of Neptune and the seventh of the solar system.

In addition, it is the only large moon that has a retrograde orbit, that is, an orbit whose direction is contrary to the rotation of the planet (something exceptional in a body of such size).

Because of this retrograde orbit and its composition similar to that of Pluto, it is considered that Triton was captured from the Kuiper belt by the gravitational force of Neptune.

“We are comparing this mission with the mission of Voyager in 1989, which was carried out with technology from the early 1970s, with a television camera connected to a fax machine,” added Karl Mitchell, project scientist. the proposed mission.

Mitchell augurs fascinating discoveries and surprising facts that will reveal new secrets and mysteries that still await in the confines of the universe.

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 91

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 93

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 94

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.
