  • New Shephard Rocket System

    New Shephard, a rocket system meant to take tourists to space successfully completed its seventh test launch.

    Note the features of the Karman Line. It is a new terminolgy in our recent space vocab.

    What is New Shephard?

    • New Shephard has been named after astronaut Alan Shephard, the first American to go to space, and offers flights to space over 100 km above the Earth and accommodation for payloads.
    • Essentially, it is a rocket system that has been designed to take astronauts and research payloads past the Karman line – the internationally recognised boundary of space.
    • The idea is to provide easier and more cost-effective access to space meant for purposes such as academic research, corporate technology development and entrepreneurial ventures among others.
    • It is built by Amazon founder Jeff Bezos’s Space Company called Blue Origin.
    • In 2018, Blue Origin was one of the ten companies selected by NASA to conduct studies and advance technologies to collect process and use space-based resources for missions to the Moon and Mars.

    How does it work?

    • The rocket system consists of two parts, the cabin or capsule and the rocket or the booster.
    • The cabin can accommodate experiments from small mini payloads up to 100 kg.
    • The cabin is designed for six people and sits atop a 60-feet tall rocket and separates from it before crossing the Karman line, after which both vehicles fall back to the Earth.
    • The system is a fully reusable, vertical takeoff and vertical landing space vehicle that accelerates for about 2.5 minutes before the engine cuts off.
    • After separating from the booster, the capsule free falls in space, while the booster performs an autonomously controlled vertical landing back to Earth.
    • The capsule, on the other hand, lands back with the help of parachutes.

    Back2Basics: Karman line

    • The Karman line is an attempt to define a boundary between Earth’s atmosphere and outer space.
    • The line is named after Theodore von Kármán (1881–1963), a Hungarian American engineer and physicist, who was active primarily in aeronautics and astronautics.
    • He was the first person to calculate the altitude at which the atmosphere becomes too thin to support aeronautical flight and arrived at 83.6 km (51.9 miles) himself.

    Locating the line

    • The Fédération Aéronautique Internationale (FAI) defines Karman Line as the altitude of 100 kilometres (62 miles; 330,000 feet) above Earth’s mean sea level.
    • However, other organizations do not use this definition. There is no international law defining the edge of space, and therefore the limit of national airspace.
    • For instance, the US Air Force and NASA define the limit to be 50 miles (80 km) above sea level.
    • The line is approximately at the turbopause, above which atmospheric gases are not well-mixed.

  • Mars ‘Opposition’ Event

    Due to an event referred to as “opposition”, which takes place every two years and two months, Mars will shine the brightest.

    Try this question from CSP 2017:

    Q.Which region of Mars has a densely packed river deposit indicating this planet had water 3.5 billion years ago?

    (a) Aeolis Dorsa (b) Tharsis (c) Olympus Mons (d) Hellas

    What is the Opposition Event?

    • ‘Opposition’ is the event when the sun, Earth and an outer planet (Mars in this case) are lined up, with the Earth in the middle.
    • The time of opposition is the point when the outer planet is typically also at its closest distance to the Earth for a given year, and because it is close, the planet appears brighter in the sky.
    • An opposition can occur anywhere along Mars’ orbit, but when it happens when the planet is also closest to the sun, it is also particularly close to the Earth.
    • It will outshine Jupiter, becoming the third brightest object (moon and Venus are first and second, respectively) in the night sky during the month of October.

    When does opposition happen?

    • Earth and Mars orbit the sun at different distances (Mars is farther apart from the sun than Earth and therefore takes longer to complete one lap around the sun).
    • In fact, the opposition can happen only for planets that are farther away from the sun than the Earth.
    • In the case of Mars, roughly every two years, the Earth passes between sun and Mars, this is when the three are arranged in a straight line.
    • Further, as the Earth and Mars orbit the sun, there comes a point when they are on the opposite sides of it, and hence very far apart. At its farthest, Mars is about 400 million km from the Earth.
    • In case of opposition, however, Mars and Sun are on directly opposite sides of the Earth. In other words, the Earth, sun and Mars all lie in a straight line, with the Earth in the middle.

    Logic behind the name

    • As per NASA, from an individual’s perspective on the Earth, Mars rises in the east and after staying up all night, it sets in the west just as the sun rises in the east and sets in the west.
    • Because from the perspective on Earth, the sun and Mars appear to be on the opposite sides of the sky, Mars is said to be in “opposition”.
    • Essentially, the opposition is a reference to “opposing the sun” in the sky.

  • Indian Sat: Another satellite made by students

    An experimental satellite developed by three students of Karur (TN) has been selected for launch in sub-orbital space by NASA.

    Try this PYQ:

    Q.The term ‘IndARC’, sometimes seen in the news, is the name of:

    (a) An indigenously developed radar system inducted into Indian Defence

    (b) India’s satellite to provide services to the countries of Indian Ocean Rim

    (c) A scientific establishment set up by India in Antarctic region

    (d) India’s underwater observatory to scientifically study the Arctic region

    Indian Sat

    • The Indian Sat is made of reinforced graphene polymer. It is 3 cm in size and weighs 64 gm.
    • It has its own radio frequency communication to transmit and receive a signal from earth to outer space. The solar cells attached to the satellite generate power for it.
    • The photographic film will absorb and measure the cosmic radiation inside the rocket.
    • It would study the effect of reinforced graphene polymers in microgravity. It would be in sub-orbital space flight for a few minutes before landing in the ocean.

    What is micro-gravity?

    • The term micro-g environment is more or less synonymous with the terms weightlessness and zero-g, but with an emphasis on the fact that g-forces are never exactly zero—it is just very small.
    • On the ISS, for example, the small g-forces come from tidal effects, gravity from objects other than the Earth, such as astronauts, the spacecraft, and the Sun, and, occasionally, air resistance.

    Back2Basics: Femto-satellites

    • Femto-satellites are satellites with a mass lower than 100 grams.
    • These new categories of satellites are, by concept, low cost devices if they are based on Commercial-of-the-Shelf (COTS) components.
    • Some examples of applications are related to low-cost missions with a short time of development.

     Kalamsat

    • Kalamsat was a communication satellite with a life span of two months launched in 2017.
    • The nanosatellite is a 10cm cube weighing 1.2 kg.
    • It will be the first to use the rocket’s fourth stage as an orbital platform.
    • The fourth stage will be moved to higher circular orbit so as to establish an orbital platform for carrying out experiments.
    • It is named after former Indian president Dr APJ Abdul Kalam and was built by an Indian high school student team, led by Rifath Sharook, an 18-year-old from the Tamil Nadu town of Pallapatti.
    • It is the world’s lightest and first-ever 3D-printed satellite.

  • Physics Nobel for discoveries about Black Holes

    Three scientists won this year’s Nobel Prize in Physics for advancing our understanding of black holes, the all-consuming monsters that lurk in the darkest parts of the universe.

    Try this PYQ:

    Q.Recently, scientists observed the merger of giant ‘blackholes’ billions of light-years away from the Earth. What is the significance of this observation?

    (a) ‘Higgs boson particles’ were detected.

    (b) ‘Gravitational waves’ were detected.

    (c) Possibility of inter-galactic space travel through ‘wormhole’ was confirmed.

    (d) It enabled the scientists to understand ‘singularity’.

    Who are these laureates?

    • Briton Roger Penrose received half of this year’s prize for the discovery that black hole formation is a robust prediction of the general theory of relativity.
    • German Reinhard Genzel and American Andrea Ghez received the second half of the prize for the discovery of a supermassive compact object at the centre of our galaxy.

    What are black holes?

    • A black hole is formed when stars collapse and can be defined as a space in the universe with an escape velocity so strong that even light cannot escape it.
    • Escape velocity is the speed at which an object must travel to override a planet or an object’s gravitational force.
    • For instance, for a spacecraft to leave the surface of the Earth, it needs to be travelling at a speed of about 40,000 km per hour.
    • Since light cannot get out, black holes are invisible and can only be tracked with the help of a space telescope or other special tools.
    • And the reason light cannot escape is mainly that the gravity inside a black hole is very strong as a result of a lot of matter being squeezed into a small space.

    Their contributions

    • Penrose has been awarded the prize for the discovery that black hole formation is a robust prediction of the general theory of relativity.
    • Genzel and Ghez have been awarded the prize for the discovery of a supermassive compact object at the centre of our galaxy.
    • Penrose’s work has shown that black holes are a direct consequence of Albert Einstein’s general theory of relativity.
    • Einstein himself did not believe that black holes exist and presented his theory in November 1915, providing a new way to look at and understand the gravity that shapes the universe “at the largest scale”.
    • Penrose used Einstein’s general theory of relativity in order to prove that the process of formation of black holes is a stable one.
    • Genzel and Ghez, on the other hand, have discovered that an invisible and an extremely heavy object governs the stars’ orbit at the centre of the Milky Way.

  • [pib] UVIT: India’s first multi-wavelength astronomical observatory

    The satellite that detected the first extreme-UV rays in the Universe from the cosmic noon celebrated its 5th birthday today.

    Try this PYQ:

    Q.“Event Horizon” is related to:

    (a) Telescope

    (b) Black hole

    (c) Solar glares

    (d) None of the above

    Ultra-Violet Imaging Telescope (UVIT)

    • The UVIT is a remarkable 3-in-1 imaging telescope.
    • Weighing all of 230 kg, the UVIT can simultaneously observe in the visible, the near-ultraviolet (NUV) and the far-ultraviolet (FUV).
    • UVIT comprises of two separate telescopes. One of them works in the visible (320-550 nm) and the NUV (200-300 nm).
    • The second works only in the FUV (130-180 nm).

    Its achievement

    • It has carried out 1166 observations of 800 unique celestial sources proposed by scientists both from India and abroad.
    • It has explored stars, star clusters, mapping of the large and small satellite galaxies nearby to our own Milky Way galaxy called the Magellanic Clouds.
    • It is an energetic phenomenon in the Universe such as the ultra-violet counterparts to gamma-ray bursts, supernovae, active galactic nuclei, and so on.
    • Its superior spatial resolution capability has enabled astronomers to probe star formation in galaxies as well as resolve the cores of star clusters (3 times better than the last NASA mission, GALEX).
    • Observations from UVIT has recently led to the discovery of a galaxy located at a distance of about 10 billion light-years from Earth and emitting extreme ultraviolet radiation that can ionize the intergalactic medium.

  • NASA’s Sonification Project

    While telescopes offer glimpses of outer space by translating digital data into stunning images, NASA’s Chandra X-Ray Center (CXC) has gone a step further by unveiling a new ‘sonification’ project that transforms data from astronomical images into audio.

    Don’t get confused with the ‘Chandra‘ considering it as an ISRO Project.

    What is the project?

    • Users can now ‘listen’ to images of the Galactic Centre, the remains of a supernova called Cassiopeia A, as well as the Pillars of Creation Nebula, which are all located in a region around 26,000 light-years away from Earth.
    • The data has been collected by NASA’s Chandra X-Ray Observatory, Hubble Space Telescope and Spitzer Space Telescope — each of which is represented by a different musical ‘instrument’.

    What is data sonification?

    • Data sonification refers to the use of sound values to represent real data. Simply put, it is the auditory version of data visualization.
    • In NASA’s recent Chandra project, for instance, data is represented using a number of musical notes.
    • With this data sonification project, users can now experience different phenomena captured in astronomical images as an aural experience.
    • The birth of a star, a cloud of dust or even a black hole can now be ‘heard’ as a high or low pitched sound.

    How did NASA translate astronomical images into sound?

    • NASA’s distant telescopes in space collect inherently digital data, in the form of ones and zeroes, before converting them into images.
    • The images are essentially visual representations of light and radiation of different wavelengths in space, that can’t be seen by the human eye.
    • The Chandra project has created a celestial concert of sorts by translating the same data into sound. Pitch and volume are used to denote the brightness and position of a celestial object or phenomenon.
    • So far, the astronomers behind Project Chandra have released three examples made using data collected from some of the most distinct features in the sky — the Galactic Centre, Cassiopeia A, and Pillars of Creation Nebula.

    (1) The Galactic Centre

    • The first example is that of the Galactic Centre, which the rotational centre of the Milky Way galaxy is.
    • It comprises a collection of celestial objects — neutron and white dwarf stars, clouds of dust and gas, and most notably, a supermassive black hole called Sagittarius A*, that weighs four million times the mass of the sun.
    • Based on data gathered by the Chandra X-ray Observatory, and the Hubble and Spitzer Space Telescopes, an image is rendered using X-ray, visible and infrared light before being translated into sound.
    • The translation begins on the left side of the image and then moves to the right.
    • Stars and other compact sources are represented using individual short notes, while a longer humming sound is used to denote clouds of gas and dust.

    (2) Cassiopeia A

    • Located around 11,000 light-years away from Earth in the northern Cassiopeia constellation, Cassiopeia A is one of the most well-known remnants of a once-massive star that was destroyed by a supernova explosion around 325 years ago.
    • The image shows the supernova remnant as a ball of different coloured filaments.
    • Each colour represents a particular element — red is used for silicon, yellow for sulfur, purple denotes iron, while green is used for calcium. Each of these filaments is also assigned its own unique sound.
    • Unlike with the sonification of the Galactic Centre, where the translation plays from left to right, here the sounds move outwards from the centre of the circular structure.

    (3) The Pillars of Creation

    • The iconic Pillars of Creation is located in the centre of the Eagle Nebula, which is also known as Messier 16.
    • The Hubble Star Telescope was used for images of the celestial structure, which comprises wispy towers of cosmic dust and gas.
    • Here too, different colours are used to represent elements — blue for oxygen, red for sulphur and green for both nitrogen and hydrogen.
    • Like with the Galactic Centre, this sound translation also plays from left to right. However, the sound has an eerie effect, with sharp whistles representing stars and low howls indicating the presence of gas clouds.

    Significance of the project

    • The sonification project aims to “incorporate NASA science content into the learning environment effectively and efficiently for learners of all ages”.
    • Over the years, NASA has been working towards making data about space accessible for a larger audience.
    • The projects like this allow audiences — including visually-impaired communities — to experience space through data.

    Back2Basics: Chandra X-Ray Observatory

    • The Chandra X-ray Observatory (CXO) is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999.
    • Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors.
    • Since the Earth’s atmosphere absorbs the vast majority of X-rays, they are not detectable from Earth-based telescopes; therefore space-based telescopes are required to make these observations.
    • Chandra is an Earth satellite in a 64-hour orbit, and its mission is ongoing as of 2020.
    • The telescope is named after the Nobel Prize-winning Indian astrophysicist Subrahmanyan Chandrasekhar.

  • Explained: Solar Cycle 25

    NASA and the National Oceanic and Atmospheric Administration (NOAA) has announced the commencement of solar cycle 25.

    Try this PYQ:

    Q. Which one of the following reflects back more sunlight as compared to the other three?

    (a) Sand desert

    (b) Paddy cropland

    (c) Land covered with fresh snow

    (d) Prairie land

    What is the Solar Cycle?

    • Like seasons on Earth, the Sun follows a cycle of 11 years, during which solar activities fluctuate between solar minima and maxima.
    • Depending on the number of sunspots detected on the Sun, scientists term it is as solar maxima (highest number of sunspots) or solar minima (lowest number of sunspots).
    • Sunspots are small and dark, yet cooler areas formed on the solar surface, where there are strong magnetic forces.
    • They start appearing at Sun’s higher latitudes and later shift towards the equator as a cycle progresses.
    • In short, when the Sun is active, there are more sunspots in comparison to fewer sunspots during the lesser active phase.
    • Maxima or minima is not a specific time in the 11-year cycle but is a period that can last for a few years.

    How are solar cycles determined?

    • One of the important elements researchers look out for on the Sun’s surface is the number of sunspots.
    • A new cycle commences when the Sun has reached its lowest possible minima phase.
    • Every time the cycle changes, the Sun’s magnetic poles reverse.

    Monitoring solar cycles

    • Since the Sun is a highly variable star, data of sunspot formation and its progress need close monitoring.
    • Data of six to eight months are required to confirm whether the star has undergone a minima phase.
    • Traditionally, telescopes were used to record sunspots and recorded data since 1755 is available.
    • With the advance in technology in recent decades, satellites are also used to make real-time sunspot observations.
    • On this basis, scientists announced the completion of solar cycle 24, which lasted between December 2008 and December 2019.
    • With the Sun’s activities having reached its lowest minima between the two cycles, the new solar cycle 25 has now commenced.

    How has the transition between solar cycles 24 and 25 been?

    • The Sun’s activities were notably lesser during 2019 and early 2020. There were no sunspots for 281 days in 2019 and 181 days in 2020.
    • Since December 2019, the solar activities have slowly picked up, corroborating the beginning of the news cycle.
    • The panel termed solar cycle 25 to be a weak one, with the intensity similar to that of Solar cycle 24.

    What solar activities affect us on Earth?

    • Solar activities include solar flares, solar energetic particles, high-speed solar wind and Coronal Mass Ejections (CME).
    • These influence the space weather which originates from the Sun.
    • Solar storms or flares can typically affect space-dependent operations like GPS, radio and satellite communications, besides hampering flight operations, power grids and space exploration programmes.
    • CMEs pose danger to space weather. Ejections travelling at a speed of 500km/second are common during solar peaks and create disturbances in Earth’s magnetosphere, the protective shield surrounding the planet.
    • At the time of spacewalks, astronauts face a great health risk posed by exposure to solar radiation outside Earth’s protective atmosphere.

     

  • Life signature on Venus

    Scientists have detected in the harshly acidic clouds of Venus a gas called phosphine that indicates microbes may inhabit Earth’s inhospitable neighbour, a sign of potential life beyond Earth.

    Try this PYQ:

    Q.Which phenomenon has Venusian winds rotating 60 times faster than the planet below on the dark side?

    (a) Super rotation

    (b) Monrotation

    (c) Dual rotation

    (d) Macrrotation

    Phosphine

    • Phosphine – a phosphorus atom with three hydrogen atoms attached – is highly toxic to people.
    • It is known to be produced only through a biological process, and not through any naturally occurring chemical process.
    • Phosphine was seen at 20 parts-per-billion in the Venusian atmosphere, a trace concentration.
    • Researchers examined potential non-biological sources such as volcanism, meteorites, lightning and various types of chemical reactions, but none appeared viable.
    • There are some other ways in which this chemical might be produced, for example, in the underbelly of volcanoes or meteorite activity, but that would have shown in much lower concentrations.

    Why study Venus?

    • Venus is Earth’s closest planetary neighbour. Similar in structure but slightly smaller than Earth, it is the second planet from the sun. Earth is the third.
    • Venus is wrapped in a thick, toxic atmosphere that traps in heat. Surface temperatures reach a scorching 880 degrees Fahrenheit (471 degrees Celsius), hot enough to melt lead.
    • Existence of phosphine is the most credible evidence yet for the possibility of life away from Earth.

    Hosting life on Venus

    • There are several things that we know about Venus that make life, as we know it, unsustainable on that planet.
    • The temperature of Venus is too high, and its atmosphere is highly acidic, just two of the things that would make life impossible.
    • It is too early to consider this as evidence for extraterrestrial life.

    Paving way for future mission

    • Missions to Venus are not new. The finding can further ignite interest in space missions to Venus.
    • Spacecraft have been going near the planet since the 1960s, and some of them have even made a landing.
    • In fact, the Indian Space Research Organisation (ISRO) is also planning a mission to Venus, tentatively called Shukrayaan, in the near future.
    • As of now, the plan is still on the drawing board. All future missions to Venus would now be attuned to investigating further evidence of the presence of life.

  • Black Holes Merger

    Billions of years ago, a collision between two black holes sent gravitational waves rippling through the universe. In 2019, signals from these waves were detected at the gravitational wave observatory LIGO (United States) and the detector Virgo (Italy).

    Try this PYQ:

    Q.Recently, scientists observed the merger of giant ‘blackholes’ billions of light-years away from the Earth. What is the significance of this observation?

    (a) ‘Higgs boson particles’ were detected.

    (b) ‘Gravitational waves’ were detected.

    (c) Possibility of inter-galactic space travel through ‘wormhole’ was confirmed.

    (d) It enabled the scientists to understand ‘singularity’.

    Why in news?

    • The cause of curiosity is the mass of one of the parent black holes, which defies traditional knowledge of how black holes are formed.

    What exactly was detected?

    • It was a signal from a gravitational wave, a relatively new field of discovery.
    • Gravitational waves are invisible ripples that form when a star explodes in a supernova; when two big stars orbit each other; and when two black holes merge.
    • Travelling at the speed of light, gravitational waves squeeze and stretch anything in their path.

    Detecting gravitational waves

    • Gravitational waves were proposed by Albert Einstein in his General Theory of Relativity over a century ago.
    • It was only in 2015, however, that the first gravitational wave was actually detected — by LIGO. Since then, there have been a number of subsequent detections of gravitational waves.
    • The signal detected at LIGO and Virgo, as described by the LIGO Collaboration, resembled “about four short wiggles” and lasted less than one-tenth of a second.

    Where did it come from?

    • Subsequent analysis suggested that GW190521 had most likely been generated by a merger of two black holes. The signal likely represented the instance that the two merged.
    • It was calculated to have come from roughly 17 billion light-years away, and from a time when the universe was about half its age.

    Some questions to verify

    • The findings led to further questions.
    • One of the two merging black holes falls in an “intermediate-mass” range — a misfit that cannot be explained by traditional knowledge of how black holes form.

    Why is it unusual?

    • All the black holes observed so far belong to either of two categories.
    • One category ranges between a few solar masses (one solar mass is the mass of our Sun) and tens of solar masses. These are thought to form when massive stars die.
    • The other category is of supermassive black holes. This range from hundreds of thousands, to billions of times that of our sun.
    • According to traditional knowledge, stars that could give birth to black holes between 65 and 120 solar masses do not do so — stars in this range blow themselves apart when they die, without collapsing into a black hole.

    Observing for the first time

    • In the merger leading to the GW190521 signal, the larger black hole was of 85 solar masses —well within this unexpected range, known as the pair-instability mass gap.
    • It is the first “intermediate-mass” black hole ever observed. (In fact, the smaller black hole to is borderline, at 66 solar masses.)
    • The two merged to create a new black hole of about 142 solar masses. Energy equivalent to eight solar masses was released in the form of gravitational waves, leading to the strongest ever wave detected by scientists so far.

    Possible reasons for its formation

    • The researchers suggest that the 85-solar-mass black hole was not the product of a collapsing star, but was itself the result of a previous merger.
    • Formed by a collision between two black holes, it is likely that the new black hole then merged with the 66-solar-mass black hole — leading to gravitational waves and the signal received by LIGO and Virgo.

  • Space industry and challenges

    The article analyses opportunities and challenges the outer space technology offers to us.

    Emerging trends in space industry

    • The price for reaching low Earth orbit has declined by a factor of 20 in a decade.
    • It enhances human space travel possibilities by leveraging new commercial capabilities.
    • According to a Bank of America Report, the $350 billion space market today will touch $2.7 trillion by 2050.
    • Starlink, the constellation being constructed by SpaceX to provide global Internet access, plans more than 10,000 mass-produced small satellites in low Earth orbit. 
    •  In a decade, 80,000 such satellites could be in space compared to less than 3,000 at present.
    • Companies such as Planet, Spire Global and Iceye are using orbital vantage points to collect and analyse data to deliver fresh insights in weather forecasting, global logistics, crop harvesting and disaster response.
    • Space could prove attractive for high-tech manufacturing too.
    • In short, an exciting new platform is opening up for entrepreneurs.

    3 Challenges

    1) Governance of outer space

    • Framework for governance of outer space as it becomes democratised, commercialised and crowded is becoming obsolescent.
    • The Outer Space Treaty of 1967 enshrines the idea that space should be “the province of all mankind” and “not subject to national appropriation by claims of sovereignty”.
    • The Rescue Agreement, Space Liability Convention, and the Space Registration Convention expanded provisions of the Outer Space Treaty.
    • The Moon Treaty of 1979 was not ratified by major space-faring nations.
    • Space law does not have a dispute settlement mechanism, is silent on collisions and debris, and offers insufficient guidance on interference with others’ space assets.
    • These gaps heighten the potential for conflict in an era of congested orbits and breakneck technological change.

    2) Acknowledging role of non-state entities

    • The legal framework related to outre space is state-centric, placing responsibility on states alone.
    • However, non-state entities are now in the fray for commercial space exploration and utilisation.
    • Some states are providing frameworks for resource recovery through private enterprises.
    • Some scholars and governments view this as against the principle of national non-appropriation, violating the spirit if not the letter of the existing space law.
    • The lack of alignment of domestic and international normative frameworks risks a damaging free-for-all competition for celestial resources involving actors outside the space framework.

    3) The arms race in outer space

    • The space arms race is difficult to curb, especially since almost all space technologies have military applications.
    • For example, satellite constellations are commercial but governments could acquire their data to monitor military movements.
    • Investment in technologies that can disrupt or destroy space-based capabilities is under way.
    • Despite concerns about military activity in outer space for long, not much progress has been made in addressing them.
    • The UN General Assembly passes a resolution on Prevention of an Arms Race in Outer Space since 1982.
    • The current geopolitical situation does not hold hope for addressing concerns of a space arms race.

    Need for space legislation in India

    • India has invested enormous resources in its space programme through the Indian Space Research Organisation.
    • More importantly, our space assets are crucial for India’s development.
    • The proposed involvement of private players and the creation of an autonomous body IN-SPACe for permitting and regulating activities of the private sector are welcome efforts.
    • However, the space environment that India faces requires us to go beyond meeting technical milestones.
    • We need a space legislation enabling coherence across technical, legal, commercial, diplomatic and defence goals.

    Consider the question “Outer space technology is expanding its horizon day by day. However, there are certain challenges the expansion of the space technology faces. What are these challenges and suggest ways to deal with such challenges.”

    Conclusion

    Our space vision also needs to address global governance, regulatory and arms control issues. As space opens up our space vision needs broadening too.
