    Starman Suits in Demo-2 Mission

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Demo 2 Mission

    Mains level: Not Much

    NASA’s SpaceX Demo-2 test flight has now been rescheduled for May 31, due to weather conditions. Apart from the test flight itself, what’s getting attention are the spacesuits that the astronauts will wear while travelling in the SpaceX capsule, called Crew Dragon.

    Try this question from CSP 2014:

    Q. Which of the following pair is/are correctly matched?

    Spacecraft Purpose
    1. Cassini-Huygens Orbiting the Venus and transmitting data to the Earth
    2. Messenger Mapping and investigating the Mercury
    3. Voyager 1 and 2 Exploring the outer solar system

    Select the correct answer using the code given below.

    a) 1 only

    b) 2 and 3 only

    c) 1 and 3 only

    d) 1, 2 and 3

    The SpaceX spacesuit

    • The so-called “Starman suits” the astronauts will wear on the Demo-2 mission have been designed by a famous Hollywood costume designer.
    • The SpaceX spacesuits are different from other spacesuits typically worn by astronauts because of their sleek design and are being described as resembling a tuxedo.
    • These spacesuits are meant to be lighter and more flexible, are equipped with touchscreen gloves, have vents that allow astronauts to be cooler while maintaining pressure inside the suit, and have an incorporated helmet and visor.
    • The helmets of these suits are 3D printed with touchscreen-sensitive gloves and the suit is all in one piece, customised for the wearer.

    How are launch-and-entry spacesuits different from EMUs?

    • The SpaceX suits are only meant to be worn inside the space shuttle and are not suitable for carrying out spacewalks.
    • Spacesuits for spacewalks, called Extravehicular Mobility Units (EMUs), are heavier than launch-entry suits (LES) and are already present aboard the ISS.
    • While inside the spacecraft, the atmosphere can be controlled, to explore and work in space, humans require that they take their environment with them because there are atmospheric pressure and no oxygen to sustain life.
    • Such spacesuits – EMUs are worn for spacewalks or extravehicular activities (EVA) conducted outside a space shuttle.
    • These provide astronauts with oxygen supply and protect them against extreme temperatures, radiation and space dust.

    What are Cicadas?

    • Cicadas are insects that spend most of their lives underground and emerge from the soil mainly to mate.
    • Once out of the ground, their life span is fairly short, somewhere between two-four weeks.
    • At present, there are about 15 active broods of these cicadas as some have gone extinct.
    • The insects are found in America’s as well as New Zealand and Australia.
    • The name 13 and 17 year refers to the number of years that cicada nymphs take to reach adulthood.
    • It is not clear why their development period is so long, researchers suspect that it may be linked to avoiding predators above the soil.

    How are the fed?

    • During this time underground the nymphs feed on sap from plant roots.
    • After this developmental period, the cicada nymphs construct a “cicada hut” and burrow their way out from the soil and climb onto any nearby tree or vegetation.

One of the earliest modernists in Indian art, he assimilated the idioms of the European modern visual language and yet was rooted in his own Indian ethos.”

    Who is the imminent personality discussed?

    Who was Ramkinkar Baij?

    • Ramkinkar Baij (1906-1980), one of the most seminal artists of modern India, was an iconic sculptor, painter and graphic artist.
    • He was born in Bankura, West Bengal, into a family of little economic and social standing and grew by his sheer determination into one of the most distinguished early modernists of Indian art.

    His works

    • One of the earliest modernists in Indian art, he assimilated the idioms of the European modern visual language and yet was rooted in his own Indian ethos.
    • His themes were steeped in a deep sense of humanism and an instinctive understanding of the symbiotic relationship between man and nature.

    Grand Ethiopian Renaissance Dam on Nile and Various Issues

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nile River, GERD

    Mains level: Not Much

    Africa’s longest river, the Nile, has been at the centre of a decade-long complex dispute involving several countries in the continent who are dependent on the river’s waters. At the forefront of this dispute, however, are Ethiopia and Egypt.

    Note: You never know when UPSC might switch map based questions away from the Middle East and SE Asia.

    Considering this news, the UPSC may ask a prelim question based on the countries swept by River Nile/ various dams constructed/ landlocked countries in the African continent etc.

    Grand Ethiopian Rennaissance Dam (GERD)

     

    • GERD is a gravity dam on the Blue Nile River in Ethiopia that has been under construction since 2011.
    • At 6.45 gigawatts, the dam will be the largest hydroelectric power plant in Africa when completed, as well as the seventh-largest in the world.
    • Once completed, the reservoir could take anywhere between 5 and 15 years to fill with water, depending on hydrologic conditions during the filling period and agreements reached between Ethiopia, Sudan, and Egypt.

    Issues with the Dam

    • While the main waterways of the Nile run through Uganda, South Sudan, Sudan and Egypt, its drainage basin runs through other countries in East Africa, including Ethiopia.
    • Egypt has objected to the construction of this dam and in Sudan has found itself caught in the midst of this conflict.
    • Due to the importance of the Nile as a necessary water source in the region, observers are concerned that this dispute may evolve into a full-fledged conflict between the two nations.
    • The US has stepped in to mediate.

    How can this lead to conflict?

    • The mega project may just allow the country to control the river’s waters, and this is essentially what concerns Egypt because it lies downstream.
    • Egypt has objected to these plans and has proposed a longer timeline for the project because it does not want the water level of the Nile to dramatically drop as the reservoir fills with water in the initial stages.
    • For the past four years, triparty talks between Egypt, Ethiopia and Sudan have been unable to reach agreements. Egypt isn’t alone in its concerns.
    • Sudan is hardly a passive observer caught in the conflict just because of its location.
    • It too believes Ethiopia having control over the river through the dam may affect its own water supplies.

    Why does Ethiopia want this dam?

    • Ethiopia believes this dam will generate approximately 6,000 megawatts of electricity when it is done.
    • 65% of Ethiopia’s population suffers due to lack of access to electricity.
    • This dam will reduce those shortages and help the country’s manufacturing industry.
    • The country may also be able to supply electricity to neighbouring nations and earn some revenue in exchange.
    • Neighbouring countries like Kenya, Sudan, Eritrea and South Sudan also suffer from electricity shortages.
    • If Ethiopia sells electricity to these nations, they may also reap benefits.

    What is happening now?

    • In the latest developments on this front, Egypt announced that it is willing to resume negotiations with Ethiopia and Sudan concerning the dam.
    • Ethiopia has however proceeded with the first stage of filling the dam saying that it does not need Egypt’s permission to fill the dam.
    • In the letter to the UNSC, Egypt also implied that the dam would cause armed conflict between the two countries.

    Back2Basics: River Nile

    • The Nile is a major north-flowing river in northeastern Africa.
    • It is the longest river in Africa and the disputed longest river in the world as the Brazilian government says that the Amazon River is longer than the Nile.
    • The Nile is about 6,650 km long and its drainage basin covers eleven countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of Sudan, and Egypt.
    • In particular, the Nile is the primary water source of Egypt and Sudan.
    • The Nile has two major tributaries – the White Nile and the Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself.
