The Russian Federal Space Agency, Roscosmos, was formed in 1992 to perform numerous civilian activities such as Earth monitoring and running the astronaut program, as well as coordinating with the Defense Ministry of the Russian Federation for military launches into space. In 2016, it opened a new launch complex called Vostochny that intended to eventually take over most of the duties of the Baikonur Cosmodrome, its current primary launch facility in Kazakhstan. The main objective of the forming of Roscosmos was the Soviet-U.S. Don’t waste time! Our writers will create an original "Roscosmos: Russian Space Exploration" essay for you Create order Space Race. This section of the Russian government made many space exploration devices such as Sputnik (1957), Soyuz 1,Luna 1, and Soyuz 11. The Luna 1 was the technology to fly by the sun. The Soviets also failed in many areas of space exploration, in 1960 a R-16 missile detonated at Baikonur and killed 150 people. The details werent known by the public, or even the affected families, for many decades due to the secrecy of the Soviet-U.S. Space Race. Another failure of the Russian Space Missions was in 2013, when a fragment of a Chinese satellite collided with the Russians small laser-ranging satellite called BLITS. The crash knocked BLITS from its original orbit and broke it into at least two fragments. The Russian Federal Space Agency over the years have had many successes and failures, but in the future they plan to make a Mars mission which is expected to launch in 2020. The idea of space exploration was started by the Russian and America, as well as other countries, in the mid 1900s as a competitive race. But today, that same competitive nature although subsided, launched a world-changing curiosity into space. Without the competition of the Soviet-U.S. Space Race, the Russians would probably never have made as many space explorations and space technologies as we have now. I believe the Soviets Federal Space Agency, Roscosmos, was the leading force of space agencies due to the competitive nature installed by the Soviet-U.S. S pace Race. Due to this driving force, Russians created the basis of space knowledge and inspires and educates scientists to explore space into the 21st century.

Alzheimers Disease - 945 Words

Alzheimer’s Disease Alzheimer’s Disease is a progressive neurological disease; it often attacks the brain tissues causing memory loss of one’s identity and regular behaviors. Statistics indicates that the rate of predicted people to get Alzheimer’s will increase briskly as time goes on. There are currently no cures for such disastrous disease, but there are currently approved treatments available that can help people within the early stages of Alzheimer’s. Once the disease is too far along, deteriorated brain cells are nearly impossible to revived or regenerate without stem cells, which have not been successfully ascertain.

Gale Opposing Viewpoint In Context on Alzheimer’s disease notifies, â€Å"[†¦] the disease threaten to bankrupt families, busines ses, and the U.S. health care system† (Gale, Paragraph 24). Consequently, without any cure for Alzheimer’s a continuation of large amount of currency is spent on medical care for people with AD. For example, Medicare, Employment Health Benefits, and families are spending an abundant amount of money for around the clock care and medications. Predicting if the assumption of the disease rate continue to rise over the years and left uncured, imagine how much more money would have to be spent for health care. If those with AD gene volunteer and participate in clinical trials for personal purposes before symptoms present, it would help researches understand the disease’s development more and create a little prospect for a cure in the near-term future. In conclusion, Alzheimer’s disease is fatal if left untreated. It should be dealt with as quickly as possible. If immediate action is taken before symptoms of AD appear, it will lessen anxiety among loved ones, pro long life span expectancy, and help further studies for a cure. Work Cited Alzheimer s Disease.

Aurora Borealis – Northern Lights

Question: Describe about the Article for Aurora Borealis Northern Lights. Answer: The coloured lights display across the night sky in the upper latitudes of the northern hemisphere are referred to as Aurora Borealis. It is imperative to underlying the physics behind these beautiful natural lights. The source of these lights is the solar wind which generates from the sun about 93 million miles away from earth. The solar winds caused in huge solar storms tend to travel huge distances in space and tend to even enter the earths atmosphere. The basic principle of auroras production is ionization of the atoms and molecules present in the magnetosphere (a component of earths atmosphere) caused due to the charged particles present in the solar wind. The excitation of the magnetospheres atoms is caused when the charged particles arising from the solar wind tend to transfer their energies to these on collision. Excitation of atoms implies that the electrons orbiting in the lower state stable energy orbits tend to jump into the higher state unstable energy orbits. However, d ue to lower stability of atoms, the electrons tend to shift to lower energy orbits for enhancing the overall stability and in turn tend to release energy in the form of visible light which is seen as the beautiful auroras. A schematic diagram of the above explanation is as shown below(Imster). In principle, the aurora light is produced by a principle which is used in the production of neon lights. The only major difference being for causing excitation of atoms the energy is provided by external electricity source. In case of aurora, this is achieved through the charged particles of the solar winds which act as natural source(Imster). This ionisation of the constituents of the atmosphere tends to emit various colours of light depending on the exact constituents and energy of the solar wind particles. At different heights, the air would contain different percentages of oxygen and nitrogen which impacts the exact colour of light produced. For instance, high amount of oxygen in the atmospheric air gives rise to red emissions whereas lower proportion of oxygen gives rise to a blue colour due to abundance of nitrogen(Akasofu). The aurora forms that occur in the polar region primarily depend on the underlying acceleration levels that are given to the precipitating particles. The optical emission is usually produced by precipitating protons at higher latitudes unlike proton auroras that are produced at comparatively lower latitudes. These auroras are normally limited to the particular zone called as auroral zone. This particular zone is approximately 3 to 6 degree wide in terms of latitude and 10 to 20 degree wide in terms of longitude. At lower latitudes, this phenomenon is not visible since the earths magnetism deflects these charged particles that are part of the solar wind to the magnetic poles that are concentrated in the polar regions(Savage). Thus, these charged particles of the solar winds do not enter the atmosphere of the lower attitudes which are free of auroras. References Akasofu, Syun-Ichi. Secrets of the Aurora Borealis.
