SpaceX launches 10 satellites from California air base

A SpaceX rocket carries 10 satellites orbiting California Sunday, two days after the company successfully launched a Florida satellite.

The Falcon 9 rocket exploded through the low fog at 13:25. PDT from the Vandenberg Air Force Base in northwest Los Angeles.

It carried a second batch of new Iridium communications satellites, which replaced its fleet in orbit with a constellation of satellites for the next generation.

Approximately 7 minutes after takeoff, the first rocket actuator returned to earth and landed on a floating platform on a ship in the Pacific Ocean, while the second stage of the rocket continued to carry satellites into orbit.

A SpaceX Falcon 9 was launched this Friday by Cape Canaveral in Florida and launched a communications satellite in orbit for Bulgaria. His first step was recovered after landing on an unmanned drone ship in the Atlantic.

California-based Hawthorne SpaceX founder Elon Musk believes that re-using rocket components will reduce the cost of space launches.

Iridium plans to create 75 new satellites for the mobile voice and data system in mid-2018, which requires six launches, all for SpaceX.

McLean, Virginia’s 3 billion effort involves complex procedures to replace 66 operational satellites used for many years. Some of the new satellites will be called spare orbiting satellites or else remain in orbit waiting to use if the latter do not work properly.

The old satellites exchange and deorbitation have already begun, said Matt Desch, CEO of Iridium, during a pre-release call with the press.

Several former satellites have moved to lower orbits to use their remaining fuel and set up solar panels for maximum drag resistance to fit the atmosphere and burn.

The first round took place on June 11, according to Desch.

“It’s hard to celebrate something like that, but these satellites have almost 20 years of service and ensuring that we were cleaned up after ourselves as we make use of our new constellation is a priority,” he said.

The new satellites also carry payloads for space monitoring and surveillance through the airline Aerion aircraft, which has implications for efficiency, economy and safety, especially in distance air space in the oceans.

“This will make a truly revolutionary aspect of air traffic control,” said Don Thomas, CEO of Aireon.

The technology, which requires the aircraft to be equipped with some equipment, is undergoing testing involving eight of the initial lots of Iridium NEXT.

The NEXT Iridium program will also put an end to so-called “Iridium flares,” whose space enthusiasts have been watching for years. New satellites do not create visible flashes of reflected light as they pass overhead.

It’s not about privilege, but accountability

It’s not about privilege, but accountability

The current stop in Karnataka between the legislature and the media reflects the “gray areas” in the functioning of Indian democracy. To be fair, we must recognize that this is not the first time these conflicts have arisen.

This may be the last. Our democracy seems more eager to present the “privileges” of focusing on “responsibilities.”

It is assumed that these privileges are enjoyed to allow one to exercise and fulfill their responsibilities for oneself.

In this controversy, both sides seem to have turned the battle into a “rights and privileges” rather than “accountability and responsibility.”

During the launch of The National Herald Benglauru, Rahul Gandhi said, “the government requires everyone to be silent,” referring to the Center. These criticisms of the position adopted by the state legislature could also argue that Gandhi’s words were not heard by his party mates.

In the same sense, we also have to ask who will “keep our guard”? What happens if the press that exists to freely and equitably articulate the different contours of the public debate, does not respect and does not respect the norms of fair play. The “fence” that can afford to eat the harvest?

The current situation of stagnation in Karnataka, where the President of the Assembly ordered the police to arrest two journalists for defaming the legislature and its members, has many facets.

First, what constitutes the “privilege” of a chosen house? Can a legislative office, by itself, prevent the press from violating the privileges and the question that must be arbitrated by an institution independent of the two? Opposition MPs have already made assumptions about the President’s motion and asked if the house wanted.

It was also reported that the House’s privilege committee would hesitate to demand the arrest of journalists. In addition, one of the complaints against journalists was presented by the President, when it was the home of a private member.

It is important to ask yourself, when you can have the “power” to take action, does not prudence encourage “to act in moderation” in relation to “the exercise of power”? We must also recognize that the media investigative journalism and the unilateral presentation of various issues leaves much to be desired.

Many reports in the media address a problem or event, either as “black” or “white,” and it is in this context that the article raised the issue of ‘keeping watch. ”

While we respect the unequivocal freedom of the press, it may be useful to think of moderation and the most powerful ombudsman means to deal with the media.
Institutions in a democracy must be respectful, do not require it. Will all the parties involved be willing to go beyond prestige and exercise greater moderation in the interest of the common good?

This does not seem likely, but it is a movement that must begin immediately, so over time, various institutions recognize and respect the role of each as the pillars of mutual democracy.

Studying asteroids that approach Earth

Studying asteroids that approach Earth

1908, there was a big explosion near the Tunguska River in Russia at the beginning of the day. There was no causality, but the witnesses reported a bright blue flash followed by thunder and a flash of glass. Almost 10 years later, scientists have led an expedition. They observed unusual features, such as trees that appeared to have been burned, standing and without branches.

The team was disappointed to have not found a crater or meteorites.
Since then, much research has focused on “impact” – it is important to be the only test case for the impact hypothesis.

Periodic reports that appeared in the days following impact were collected to establish side effects – an earthquake occurred on the Richter 5 scale. Shock waves were detected.

The devastated area was about eight kilometers wide. Atmospheric effects have also been reported. People saw about 100 km of a cylindrical pillar of light blue fire down near the horizon just before the earthquake shook buildings.

Impact is a concern for all of us. Such a study is important so that we can survive. Several hypotheses have been developed. Although it is stated that these are comets, another said that it was a sudden release of natural gas from the earth itself.

The possibilities of these studies are rare. A collision of an asteroid in Chelyabinsk February 15, 2013 provided another opportunity: the asteroid much less the size of a small plane and exploded without creating a crater. The effect of the impact was 500 kilotons in the air blast.

Eugene Shoemaker, an Americangeologist and one of the founders of the field of planetary science, who proposed the Impact theory of lunar craters has also made estimates of impact energy. The effects on the atmosphere, the biosphere have been well studied. It states that the impact was responsible for the massive extinction of dinosaurs 65 million years. The impact crater is identified by a huge circular area known as the KT boundary near Mexico.

The importance of studying these asteroids approaching Earth was made some time ago and special research projects have been initiated. Tracking near-Earth asteroids (NEAT), researching near-Earth asteroids of Lincoln (linear) and similar uses robotic telescopes to explore the sky so that the body moves quickly near the ground. Near-Earth asteroids may be too small to be seen even with moderately sized telescopes. A record of potentially dangerous asteroids near Earth (Phnea) is maintained and these objects are tracked.

The Phnea list increases rapidly with the arrival of new sensors and new tracking telescopes.

There are still a million identified asteroids that could be derived from this list. The approximation distance is usually given in LD units, which represents the lunar distance (384,000 km). For example, the designated asteroid 2014 BS5 moved to land at a distance of 3.12 LD July 23. This is approximately 30 to 50 m in diameter (if circular), and will be a good target for study using radar images.

Therefore, Phnea pose a risk to the Earth, and the consequences of an impact can be serious. We have the technological ability to detect.

The most recent ideas about surveillance and diversion of dangerous people away from the impact of the earth are experienced.
There are a handful of asteroids crash on earth was known. Some of them had names like Lost City, Pribram, Peekskill and Innisfree. They were very small and their impact has not done serious damage.

However, there is a larger body that is known as long as they are land once every three or five years. The nearest approach to Apophis, about 370 km is scheduled for 13 April 2029, when it is likely to be at a distance of 36 000 km.

June 30 is observed as an asteroid day and commemorates the anniversary of the impact of a Tunguska asteroid.
