Do You Have What It Takes To Be NASA’s Next Planetary Protection Officer?

Do You Have What It Takes To Be NASA’s Next Planetary Protection Officer?

Do You Have What It Takes To Be NASA’s Next Planetary Protection Officer?

The survival of life on Earth (and other parts) can rest on the shoulders of the next head of NASA’s Planetary Protection – and they are having the applications.

The job offer has provoked headlines on how the space agency is looking for a person to defend our planet against foreigners. But he is more concerned about microorganisms than the little green men.

And it is true that the role is to prevent the Earth from being contaminated with extraterrestrial material, for example from samples taken from the mission, work was also focused on preventing the pollution of Earth planets and moons that humans to explore.

Ari Shapiro from NPR talked about working with someone who knows what is needed – former planetary protection chief Michael Meyer. He is now the chief scientist of NASA’s Mars Exploration Program.

Gradually, as researchers explore places that could harbor life, “when you do samples, there is a possibility that you bring something into the life of another planet,” Meyer said.

“In this case, care must be taken to maintain these samples until it can be determined whether or not they can be dangerous in these samples.”

Explain that “the same kind of work is that you have to be conservative,” because we can not know if an alien sample is dangerous or not.

In the same way, scientists look for life, which does not want to confuse an underground microbial Earth with a revolutionary discovery of life on another planet.

That’s why Meyer has spent his time “to make sure the ship was traveling somewhere else was actually pretty clean, so you do not mind polluting the planet we’re trying to explore.”

It also highlights a number of potentially unexpected skills that are useful: diplomacy.

The planetary protection officer “is in charge of other countries also sending spacecraft to the targets of opportunity like Mars and [the moon of Jupiter] Europe.” The European Space Agency also has a similar role, but other countries with space programs do not.

“We are not in the business of telling other countries how to run their business, but we must be careful what they do because when we work with them, it is our responsibility for NASA to ensure as we explore safely,” added Meyer .

However, all missions do not require the same level of cleanliness. He explains that “planetary protection has a gradation of concerns.”

For example, sending a spacecraft to an asteroid that is not considered to have life potential requires a less conservative approach than sending a spacecraft to Mars. In places that could harbor life, Meyer said, “you have to sterilize spacecraft or sterilize instruments that can affect the region.”

Will Swift-Tuttle hit or miss?

Will Swift-Tuttle hit or miss?

Have you heard of the comet called 109P / Swift-Tuttle? Although the P indicates that this is a periodic comet (orbital period of less than 200 years), Swift-Tuttle is the two individuals who discovered the comet at the same time, days between them.

Comets are usually named after their discoverer or telescope or the Observatory used in the discovery.

In the case of this comet, however, Lewis Swift was discovered on July 16, 1862, and Horace Parnell Tuttle did the same ways July 19, 1862. Therefore, it was just that the comet is the name of the two.

Taking 133 years to orbit the Sun once, Swift-Tuttle kite is large with a core that exceeds 26 km. A ball of ice dust, rock and a dark organic matter like any other comet, follows a very pronounced inclination with respect to the planets of the solar system.

Consequently, this comet brings much speed as it passes through the Earth as it plunges into the solar system to approach the sun and go. In fact, the spectacular meteor shower that you see every August in mid-August is created by the dust and debris of the Swift-Tuttle.

Despite the kite that takes 133 years to traverse Earth, star rain, which is among the most popular for spectators in the northern hemisphere every year occurs as a result of the earth moving in the orbit track of the Kite.

This connection between the comet and meteor shower was discovered within three years after the discovery of the comet – by Giovanni Schiaparelli in 1865.

Catastrophic forecast

While everything was fine for more than a century after its discovery, a catastrophic prediction was made in 1973.

With limited observational data available and based on comet orbit calculations, astronomer Brian Marsden of the Harvard-Smithsonian Center for Astrophysics predicted that comet Swift-Tuttle might collide with Earth in 2126.

Observation in 1992

This meant that the observation of the comet during its approach in 1992 became even more important. With the technology available to them, astronomers were able to obtain accurate measurements during their last visit.

Based on these data, and the incorporation of complex calculations to take into account the gravitational effects of the sun and other planets of the comet, a revised model was obtained for its movement.

The observation in 1992, and relatives of data close to Earth, have allowed astronomers to be convinced, without a doubt that the collision in 2126 will be virtually impossible. Having said that, however, it is not possible to exclude the collision forever.

Oldest known asteroid family discovered

Oldest known asteroid family discovered

Astronomers have identified the oldest known family of asteroids, which extends throughout the interior of the main asteroid belt, using a new research technique.

The main belt contains a large number of irregularly shaped asteroids, also called planetesimals that orbit the Sun between Mars and Jupiter.

As technology improvement telescopes are smaller and more distant asteroids, astronomers at the Southwest Research Institute (SwRI) in the United States identified bodies similar groups grouped in similar orbits.

These familiar objects are probably fragments of catastrophic collisions among the largest asteroids long ago, the researchers said.

Finding and studying families of asteroids allows scientists to better understand the history of asteroids in the main belt.

“By identifying all the families of the main belt, we can determine which asteroids were formed by collisions that could be some of the original members of the asteroid belt,” said Kevin Walsh, the astronomer SwRI.

“We have identified all known families and their members and found a huge gap in the main belt, inhabited by a handful of asteroids,” said Walsh, co-author of the research published in the journal Science.

“These relics should be part of the original asteroid belt. This is the real price, to see what the main belt looks like right after its formation,” he said.

The identification of the oldest families of asteroids, a billion years, is difficult, because over time, an extension of the family, according to researchers.

When asteroids in orbit around the sun, their surfaces heat up during the day and cool at night. This creates waves that can be a kind of mini-propeller, causing the asteroid to drift widely over time.

After thousands of years, family members would be almost impossible to identify until now.

The team used a new technique, looking for data on asteroids from the inner region of the tape to the old and separated families. They looked for the “edges” of the families, these fragments have moved away.

“Each family member is derived from the family center in a way that depends on their size, with young children getting faster and farther than the older,” said team leader Marco Delbo, an astronomer Observatory of the French Riviera in Nice, France.

“If you are looking for size and distance correlations, you can see the shape of the old families,” Delbo said.

“The family we have identified has no name because it is unclear what the asteroid father is,” Walsh said.

“This family is so old it seems to have formed there more than 4 billion years ago before the gas giants in the outer solar system moved to their current orbits,” a-t said.

The team plans to apply this new technology to the entire asteroid belt to reveal more about the history of the solar system by identifying primordial asteroids and fragments of collisions.

South China Sea dispute: Vietnam challenges China at security talks

South China Sea dispute: Vietnam challenges China at security talks

South China Sea dispute: Vietnam challenges China at security talks

MANILA: Vietnam has urged other Southeast Asian countries to take a stronger stand against Chinese expansionism in the South China Sea, while a tense regional security forum began on Saturday with North Korea also criticized for Its nuclear program.

Prior to the launch of the 10-member ASEAN East Asian Foreign Ministers’ annual meeting, Vietnam has made a bold play against China with a series of suggested changes to a planned joint communique.

It paved the way for a few days of diplomacy in the Philippine capital, Chinese diplomats, the US, Russia and North Korea have joined their counterparts from ASEAN and other countries Asia and the Pacific for talks Of security Sunday.

The meetings will be held when the UN Security Council will vote this weekend in a resolution drafted in the United States to reinforce sanctions against North Korea to punish the isolated regime for its missile tests.

The United States said it will also seek to create unified pressure in the North, in the case of Manila – known as the ASEAN Regional Forum.

Following their own day of Saturday meetings, ASEAN Foreign Ministers issued a joint statement expressing “serious concerns” over the first two North Intercontinental Ballistic Missile tests conducted last month.

“These developments seriously threaten peace, security and stability in the region and the world,” the statement said.

But the conflict in the South China Sea – one of the other powder problems in Asia – did not have much less consensus with Vietnam that resisted Philippine efforts to appease Beijing, diplomats told AFP.

On Friday night, Vietnam has tried to insert a difficult language against China in an ASEAN statement, which was to be released after Southeast Asian ministers have completed their own talks Saturday.

According to a copy of a draft obtained by the AFP, Vietnam has pressed for ASEAN to express its deep concern about the “construction” at sea, in reference to the construction of ramps built in China by artificial islands in the waters in Dispute in recent years.

Vietnam also wanted ASEAN underlined in the statement that a code of conduct intended for the sea with China would be “legally binding” that Beijing opposes.

Chinese media thinks PLA can annihilate Indian Army. Can they? A fact check

Chinese media thinks PLA can annihilate Indian Army. Can they? A fact check

Chinese media thinks PLA can annihilate Indian Army. Can they? A fact check

Doklam broadcast between the Indian Army and the Chinese Liberation Army began in the month of June. In July, a report from the CAG (Comptroller and Auditor General), presented in Parliament, said that the Indian army has no ammunition to fight in a war for more than 10 days.

And now – in August – Chinese state media said the Chinese PLA could “destroy” the Indian army if a war broke out between two armed Asian neighbors.
A Global Times – a spokesman for the Chinese government’s hardline – section said: “If the war extends, PLA is fully capable of annihilating all Indian troops in the border region.”

The article in Global Times described the Indian Army as “far behind” the force compared to the PLA. He said: “It is a war with an obvious result because the PLA has done enough preparation for the military confrontation. The government of Prime Minister Narendra Modi must be aware of the power of the car and the logistics of the PLA.”

The pretension of Chinese state media demands a glimpse of how the armies of India and China are stacked. According to the Global Firepower website – following the military forces of more than 100 countries – India and China are ranked among the 4 and 3 133 military powers of the world.

China’s PLA is the largest military power in terms of number of troops employed by the latter followed by the Indian army. China has approximately 22.6 lakh soldiers in its army, while the Indian army has 13.6 lakh troops active. This gives China a specific numerical advantage over India, but there are other factors at play.

If the elements of the reserve army are taken into account, China’s relative position weakens relative to India. The Indian Army has about 28.44 lakh soldiers from the reserve while the Chinese PLA has about 14.52 lakh soldiers in the reserve elements.
According to statistics of global firepower, total military personnel in the Indian Army is about 42.07 lakh while for the Chinese PLA, the total force is at 37.12 lakh. The Indian Army has 4,426 tanks while the Chinese PLA 6457.

This number seems larger on paper, but in reality, Chinese tanks should be made in a much larger border area compared to India. On the other hand, the Indian army has 6,704 armored combat vehicles, while PLA has only 4788.

China has a numerical advantage in self-propelled artillery with 1710 to 290 from India. China also has 1,770 rocket projectors compared to 295 in the Indian Army. But in towed artillery, the Indian Army is still numerically superior Chinese PLA. The Indian Army has 7414 artillery towed, while PLA has 6246 this type of vehicles.

China has 1,271 fighter jets and interceptor while the Indian Army has 676 jets of this type. Similarly, China has 1,385 aircraft then attack the Indian air army has 809 combat aircraft. But the critical point here again is that the area over which China has put its service department is almost three times that of India.

Ugust 5 étant le délai pour produire la déclaration d’impôt sur le revenu (ITR) pour l’exercice financier 2016-17, il vous reste seulement quelques heures pour le faire sans pénalité. Le gouvernement a prolongé le délai de dépôt de la déclaration de revenus (ITR) pour l’exercice financier 2016-17 au 5 août à partir du 31 juillet précédent.

Hier, le service de l’impôt sur le revenu a ajouté que ses bureaux extérieurs resteraient ouverts jusqu’à minuit aujourd’hui pour faciliter le dépôt de l’impôt sur le revenu (ITR).

Vous avez également la possibilité de déposer votre déclaration de revenus en ligne. Le dépôt en ligne de la déclaration de revenus est très pratique et assure également le secret de vos informations personnelles. (Lire: Comment déposer un relevé d’impôt sur le revenu en ligne)

10 choses à savoir sur la déclaration de revenus de cette année:

1) La liaison du numéro Aadhaar avec le PAN (Numéro de compte permanent) d’un contribuable a été rendue obligatoire pour le dépôt d’un ITR, à compter du 1er juillet. Bien que les déclarations de revenus puissent être déposées avant le 5 août, le lien Aadhaar-PAN peut Soit jusqu’au 31 août.

2) Aux fins du dépôt électronique, il suffirait maintenant de citer Aadhaar ou le numéro d’accusé de réception pour avoir demandé Aadhaar sur le site de dépôt électronique.

3) Le service fiscal a néanmoins averti que les retombées (ITR) ne seront pas traitées tant que le lien d’Aadhaar avec PAN n’est pas terminé. (Lire: Comment associer PAN-Aadhaar en 3 voies)

4) Cette année, le service des impôts a également demandé aux contribuables de déclarer les dépôts en espèces effectués dans des comptes bancaires cumulés à Rs. 2 lakh ou plus, après la démonetisation entre le 9 novembre et le 30 décembre de l’année dernière, dans leur retour.
5) Les experts disent que les contribuables doivent faire preuve de prudence tout en réclamant des prestations HRA. On s’attend à ce que les réclamations d’HRA soient étroitement examinées compte tenu de l’introduction constante de mesures au cours des dernières années, affirme Sandeep Sehgal, directeur de la fiscalité et de la réglementation chez Ashok Maheshwary & Associés LLP.

“En fait, les chances sont plus grandes si la réclamation n’apparaît pas dans le Formulaire 16 mais réclamé dans le retour”, ajoute-t-il. (Lire: Pouvez-vous réclamer les avantages fiscaux d’HRA sans PAN du propriétaire?)

6) Le dépôt de la déclaration de revenus (ITR) a changé cette année en ce qui concerne les formulaires à utiliser. Le Département de l’impôt sur le revenu a prescrit de nouveaux formulaires pour le dépôt des déclarations de revenus.

Un formulaire simplifié d’une page, appelé «ITR-1 Sahaj», a été introduit pour les personnes ayant un revenu provenant du salaire, de la pension, des biens d’une maison et des revenus provenant d’autres sources. Le service fiscal a supprimé des colonnes qui ne sont pas fréquemment utilisées par les contribuables. (Lire: Changements clés à connaître cette année)

7) Après avoir envoyé le retour, vous devez le vérifier. Selon les lois fiscales actuelles, vous pouvez vérifier votre retour dans les 120 jours suivant le dépôt. Une fois qu’un retour est déposé par e-filed, le service de l’impôt sur le revenu envoie l’ITR-V à l’identifiant du courrier électronique enregistré.
La vérification peut être effectuée tant hors ligne que en ligne. En mode hors connexion, vous devez signer l’ITR-V et l’envoyer au service des impôts. Le mode de vérification en ligne est plus facile et peut se faire instantanément via les modes Aadhaar OTP et Internet banking entre autres.
