Space Missions; Insights from the past

0

Many wondered how these space agencies design a space mission. Well, for the starters, they PLANET (pun intended). Designing and execution of a space mission require vast financial resources, years of planning, hard work, and collaboration of different teams comprising world-class professionals. But before going into these details, we will enlighten you about the history and space missions of NASA and ESA.

NASA was established on October 01, 1958, and has a unique history of space exploration and technological achievements of aeronautics and astronomy since its inception. Decades after its foundation, NASA has successfully landed a human on the moon with Apollo 11 mission in July 1969, explored the atmospheres of planets like Mercury and Jupiter with Voyager 1 and Voyager 2. Cassini Huygens, a joint NASA/ESA spacecraft, launched in 1997, has been orbiting this ringed plant since its landing in 2004 and taking stunning imagery of planet’s rings, moons and planets.

Spirit and Opportunity, the twin Mars Exploration Rovers, landed on opposite sides of the planet in January 2004 and provided evidence of liquid water on the surface of Mars. With the Hubble telescope, astronomers can peer deep into the universe to see the cosmos more clearly. Throughout history, however, there have been several failures along with the many successes. The Challenger and Columbia accidents, being the most tragic of accidents.

The European Space Agency (ESA), an international intergovernmental organization of 20 Member States, was founded on May 30, 1975. The “raison d’être” of ESA is cooperation among the European States in space research and technology and their space applications. ESA started working on the launch of Ariane in 1974 and launched Ariane 1 successfully in 1979, followed by successive launches of Ariane 2, 3, and 4. The Ariane heavy-lift launch vehicle scheduled to launch James Webb Space Telescope in 2018. In 1986, ESA launched the Giotto Space probe to examine the core of Halley’s Comet, and in 1990 Ulysses spacecraft explored the Sun’s Polar Regions.

Joint ESA-NASA Solar observation mission SOHO, launched in December 1995, provides real-time data for space weather forecasting. At the beginning of the 21st century, ESA launched the Mars Express orbiter and its lander, Beagle 2. With the launching of the Columbus laboratory on the International Space Station in 2008, ESA became a full partner in the operation of the station. Huygens probe landed on Titan in 2005 was the first-ever human-made object to land in the outer Solar System. Rosetta, orbiter mission studying comets and their evolution, was launched in March 2004.

In May 2009, Herschel was launched, the Infrared space observatory missions for general astronomy. NASA and ESA are collaborating to detect and accurately measure gravitational waves (tiny ripples in the fabric of space-time) using Laser Interferometer Space Antenna (LISA), which is planned for launch in 2034. For years to come, ESA has many robotic and human spaceflight missions already in the pipeline, such as Jupiter Icy Moon Explorer (JUICE) is planned for launch in 2022 to study Jupiter and its three moons and ExoMars rover launching July 2020 to explore Mars in collaboration with Roscosmos.

When Moon eclipse the Sun

0

A solar eclipse sets in when the Moon moves between the Sun and Earth, and blocks out the Sunlight for a specific period of time and cast a shadow on parts of Earth. Since the Moon’s shadow is not big enough to engulf the whole earth, so the shadow is always limited to a certain area. As Earth and Moon are in constant motion with regards to each other, this area changes during the course of the eclipse. Earth continuously rotates around its axis while it orbits the Sun, and the Moon orbits Earth. This is the reason why solar eclipses seem to travel from one place to another.

A partial Solar eclipse observed around the globe today early morning. There are reports that in some parts like Singapore and UAE, thousands dazzled by rare “ring of fire” which is also coined as “Diamond ring’ sometimes.

Millions gathered, from casual onlookers to astronomy enthusiasts armed with the telescope and captured stunning glimpses of Solar eclipse around the world. Her we are sharing a few astrophotographs.

LARRY PAGE; A computer scientist and Internet entrepreneur.

0

Larry Page, born as Lawrence Page, is an American entrepreneur and computer scientist who, along with Sergey Brin, co-founded Google Inc., the search engine giant that offers a wide range of internet products and services. Google initiated as an online search firm and gradually expanded its operations to other internet related areas. As the son of computer professionals, Larry’s fascination with computers started at an early age. As a child, he showed a keen interest in technology, business, and innovation

While studying Computer Science at Stanford University, he met Sergey Brin with whose assistance he created a search engine that returned results based on relevancy. Larry and Brin launched the company under the name ‘Google Inc’ in 1998. They both served as co-presidents until 2001 when Eric Schmidt was appointed as Chairman and CEO of Google. In 2011, Larry officially became the CEO of Google, while Schmidt continues to serve as executive chairman. Larry is also a member of the Board of Directors of the company. He has an interest in renewable energy technology and philanthropy. Google.org, the philanthropic branch of the company, was set up in 2004. It basically deals with issues of climate change and renewable energy.

Larry Page and Sergey Brin

During his Ph.D. at Stanford, he met fellow researcher Sergey Brin while working on a research project in 1995. By 1996 they had built a search engine – initially called ‘BackRub.’ It was operated on Stanford servers for many months.

Larry and Brin decided to incorporate their project as a company. Sun Microsystems co-founder Andy Bechtolsheim played a significant role in financing the company as he wrote a check for $100,000 to the entity that had not even come into existence as yet.
In September 1998, the project, now renamed as ‘Google,’ was officially incorporated as a company. Eric Schmidt was appointed as the CEO in 2001, while Page and Brin became the presidents of products and technology, respectively.

In 2004, Google launched Orkut, a social networking site, and introduced Google Desktop search. The same year, Google held its Initial Public Offering (IPO), which made Page and Brin billionaires. The philanthropic wing of Google, Google.org, was formed to contribute towards social issues and causes.
The year 2005 was quite productive for Google. Google Maps, Blogger Mobile, Google Reader, and iGoogle were released that year. The next year, Google acquired Youtube and introduced the chat feature in Gmail.
Google entered into a partnership with China Mobile and Salesforce.com in 2007. The company also signed partnerships to make Google Apps for Education freely available to thousands of students in Kenya and Rwanda.
In 2008, Google launched Google Sites and a new version of Google Earth. Google Health, a personal health information centralization service, was also released in the same year, but the service was discontinued in 2011 when it was unable to achieve the desired impact.

iCase for Mac was launched in January 2009, followed by Google Latitude and the latest version of Google Earth. Google Ventures, a venture capital fund for supporting new technology companies, was also introduced the same year.
In 2010, Google acquired Aardvark and Picnik. The Google Apps Marketplace, a new online store for integrated business applications, was launched to enable customers to easily manage cloud applications.
In January 2011, Larry Page was made the CEO. Eric Schmidt, the former CEO, continues to serve the company as Executive Chairman. Google acquired Admeld and Zagat intending to provide improvised services to its clients.

Larry Page’s most prominent work is the formation of Google. Google, founded in 1998, is the world’s leading search engine, serving millions of users worldwide. Besides search, Google offers many other products and services like Gmail, Blogger, Google Maps, Picasa, etc.
The charitable arm of the company, Google.org, was formed in 2004. The organization is dedicated to finding technological solutions to help address global challenges like hunger and poverty.
In 2002, Page and Brin were named in the MIT Technology Review TR100 for being among the top 100 innovators in the world under the age of 35.
The World Economic Forum named Page as a Global Leader for Tomorrow in 2002.

Larry and Brin received the prestigious Marconi Foundation Prize (2004), which is given to honor significant contributions in science and technology. They were also elected Fellow of the Marconi Foundation at Columbia University.

Earth’s Magnetic North Pole Crosses Prime Meridian

0

Scientists have found that the magnetic north pole of the Earth has crossed the prime meridian. It has been in motion at a higher speed than expected and within the past two decades, it has moved on from the Canadian Arctic to Siberia with a rate of more than 50 kilometers.

The data was released on 10 December by the National Centers for Environmental Information and British Geological Survey which along with telling about the current speed, have predicted that the movement of the magnetic north pole will continue, although, at a much slower rate.

There is a need to understand and deeply study the model as it used in the calibration of different equipment for navigation including the GPS (Global Positioning System).

The magnetic north pole has moved on from the Canadian Arctic to Siberia  (NOAA NCEI/CIRES; ScienceAlert)

The magnetic field of our planet is produced when the outer core, which is made of iron, movies, and results in a complex north-south field. It is currently facing a reduction in strength due to unknown reasons. This is also one of the reasons for the movement of the magnetic north. According to the National Centers for Environmental Information, its location in the earlier part of 2019 was found to be at 86.54 N 170.88 E, within the Arctic Ocean.

After every five years, a new version of the World Magnetic Model is released when scientists recalibrate and carefully study the behavior and movement of the Earth’s magnetic field. The expected 2020 model features a “Blackout Zone” as well which is the area around the magnetic north and compasses are unable to give the correct information about the right direction as true north isn’t easily identified. This map also shows magnetic northeast of the prime meridian, which was set as the official point and marker of zero degrees, zero minutes and zero seconds in the geographic coordinate system.

Scientists are working to develop a black hole movie

0

This year, some great achievements were made in the field of science and one such thing was the first-ever image of a black hole and its event horizon. This enigmatic phenomenon has mesmerized and confounded scientists and researchers for decades and more work is being done to understand it better.

To capture the image, a huge telescope was made by connecting seven observatories located in different parts of the world, which helped in stitching together the image of a black hole. It proved the existence of event horizons and Einstein’s theory.

The image focused on a galaxy, M87 whose heavyweight and size made it easy to study. The gases moving around it were slower than those of others and its brightness remained consistent.  For another black hole Sagittarius A, which is located in the center of the Milky Way, there is a need to develop a movie as it changes its appearance very quickly as compared to M87’s black hole.

EHT (Event Horizon Telescope) team member Katie Bouman, a data scientist at Caltech, says that it can be done by breaking up the observations made in a night into different parts and then joining them together. But due to the lack of enough information and data, it is extremely hard to do that.

So, the team is developing other methods that can eliminate the gaps and breaks and provide information on how the black hole moves forward in time. This can help to understand in-depth, the structure and workings of a black hole. The black hole of M87 may also get a movie. Astrophysicist Kazu Akiyama says, “Our observations provided good evidence that M87 is actually changing [within] the timescale of a week.” The changes may also disclose about its rotation and spinning of magnetized plasma.

A great discovery

In the earlier part of 2019, scientists revealed the first-ever direct image of one of the most mysterious things in the universe, the black hole, which was previously unseen and considered to be non-observable. The supermassive black hole seen in the image released is a halo of dust and gas tracing the outline of the accretion discs of the monster body in the core of Messier 87 galaxy, some 55 million light-years away from the earth. The phenomenon itself–a trapdoor from which nothing and absolutely nothing can escape– it is considered that black hole cannot be seen and only the shadowy edges of hot swirling clouds of gas, destined to be sucked in by the monster, are visible.

The breakthrough image was unveiled by a team of more than 200 scientists working on the Event Horizon Telescope (EHT), a network of eight radio telescopes spread from locations in Spain, Chile, Antarctica and other parts of the world. These images will bring revolution in our understanding of one of the most mysterious things in the universe.

Giant Panda Babies Are Born ‘Undercooked,’ and this is still a mystery

Three cubs in a hospital after a few weeks of birth

There are various theories presented why Giant panda babies are born weirdly tiny and underdeveloped? But most of them turned out to be wrong. Some researchers suspect that the newly born pandas are tiny as compared to their moms due to hibernation: At some point, bears started cutting short their pregnancies to avoid gestating during their hibernation, and now that trait is baked into every bear species — even pandas, which don’t hibernate.

Though this theory turned out false and new research shows that Pandas are born exceptionally tiny and underdeveloped which sometimes referred to as “undercooked”. And other bears, including species that do hibernate, are born with robust, mature skeletons.

Peishu Li, the lead author of this research, an undergraduate at Duke University at the time of the research and is now a doctoral student at the University of Chicago, said in a statement that newly born Panda babies weigh just about 3.5 ounces (100 grams), which indicates they are 9 times smaller as compared to their mothers. Only a couple of other species, including kangaroos and echidnas, have similar weight differences at birth. Still, it is nearly possible as a truthful universal bear story.

Li and her co-author, Duke, biology professor Kathleen Smith, researched two of preserved cubs or newly born pandas. They used a CT scanner to build 3D models of the unfortunate critters’ skeletons and scanned newborn grizzlies, sloth bears, polar bears, dogs, a fox, and other animals. Comparing all the skeletons, Li and Smith found that pandas appeared to have uniquely under-developed bones at birth.

Alpha Monocerotids didn’t really live up to the hype

0

Last month, there was the prediction of a beautiful Alpha Monocerotids meteor shower. But, the weak shower left many disappointed.

The prediction was shared by scientists from the SETI Institute and NASA’s Ames Research Center who along with other fellows calculated the estimated time and distance of the outburst. The provided time was 11:50 pm ET (or 04:50 UT) and the shower was predicted to be the brightest at 15 minutes. The total expected time was 40 minutes. The best views were thought to be in South America, Western Europe, etc.

The first time the Alpha Monocerotids was observed in 1925 in Virginia. Witnesses saw “three bright meteors” within a minute and noticed and marked its location around the Orion constellation. It was later observed in 1935 in India and almost 100 meteors were counted in a span of around half an hour. And they have observed quite sometimes in the skies around the world.

Here are some images of the shower.

The Last Cold Moon of The Decade

0

The last full moon of the decade occurred yesterday. It’s called the full “cold moon”. The Moon appeared full all night, first sighted in the east with a saffron-colored tinge as it climbs just above the horizon. The full moons usually brighten since the side catching the sunlight is facing earth. That means the Sun, Moon, and Earth are all in a nearly perfect lineup.

This December full moon was dubbed a “cold moon,” for reasons everybody (well, everyone except folks in Pakistan) can probably guess. Let’s take a tour of some of the fascinating sights of this cold moon, captured worldwide.

While the auspiciously timed the full moon was a beacon of curiosity for some, it’s slated to put a damper on tonight’s Geminid meteor shower, which will outshine many of the fainter meteors.

The ‘Tiger Stripes’ on Icy Saturn Moon Enceladus finally explained

Enceladus, one of the moons of Saturn got overwhelming attention and attraction of scientists in a few years. The data obtained from Cassini spacecraft has been analyzing and with each coming day, some more mysteries are getting resolved. The ‘Tiger stripes’ of Enceladus are one of them, and a piece of good news is that the Weird Physics behind ‘Tiger Stripes’ Finally Explained.

Enceladus has been of particular interest to scientists ever since it was observed by NASA’s Cassini spacecraft. After analyzing Cassini’s data, they detected an icy, subsurface ocean on the moon and strange, tiger stripe markings on Enceladus south pole that are like nothing else known in our solar system. Icy material from Enceladus’ ocean spews into space through these stripes, or fissures, in the moon’s surface. These stripes are parallel and evenly spaced, about 130 kilometers long and 35 kilometers apart, and are continually erupting with water ice.

New research performed at Hemingway and colleagues Max Rudolph of the University of California, two scientists Davis, and Michael Manga of UC Berkeley unveiled the physical forces on the moon that cause these fissures to form and keep them in place. The team was also figured out why these cracks are even spaced and only found on the south pole of the moon. 

The study shows that Enceladus is not a frozen solid, because the gravitational changes caused by its eccentric orbit around Saturn stretch it out slightly. It shapes deformed and causes the ice sheets at the poles to be thinner and more susceptible to splitting open. The team concluded that the fissures that make up these tiger stripes could have formed on the moon’s north pole just like the south pole, but the south pole cracked first.

Pride of the Nation; Dr. A Q Khan

0

Dr. Khan is a Pakistani nuclear scientist, known as the pride of the nation and the father of the Pakistan atomic bomb program. Dr. Khan headed Pakistan’s nuclear program for 25 years. He played a crucial role in strengthening Pakistan’s national security against India and other enemies of the nation. He is the only Pakistani scientist who has been awarded high civil rights twice.

Early Life and Career

This genius and patriot man was born on the land of Bhopal in 1963. After five years of independence, he migrated to Pakistan. He continued his further education at St. Anthony’sAnthony’s High School, and later he joined College of Karachi, where he studied physics and mathematics as major subjects. Later on, He moved to West Germany for higher education. He obtained a Master of Science (Technology) in 1967 from Delft University of Technology and then a doctorate in metallurgy from the Catholic University Leuven (Belgium) in 1972. He excelled in the field of metallurgy- the art of building centrifuges; by attending several courses in metallurgical engineering.

He also served in the URENCO consortium.

From May 1972 to December 1975, Dr. A Q Khan worked as a scientist on a nuclear plant in a Physics Dynamic Research Laboratory (also known as FDO), based in Amsterdam. Meanwhile, he also served in the URENCO consortium, specializing in the manufacture of nuclear equipment.

Contribution to Pakistan’s Nuclear program

Right after India declared their nuclear design, Zulfiqar Ali Bhutto called an urgent meeting of Pakistani scientists on January 20, 1972, and put forward a dire need to carry out the task of nuclear explosions. Pakistan Atomic Energy Commission was appointed to supervise this task. On September 17, 1974, while Dr.Khan was working for URENCO in the Netherlands, he wrote a letter to Zulfiqar Ali Bhutto offering his services as a nuclear scientist, and he also suggested him to adapt the uranium route in building a nuclear weapon. He headed to Pakistan in December 1974, met Bhutto in person, and convinced him to go with his uranium route rather than the plutonium.

Initially, he worked in coordination with Munir Ahmed, head of Pakistan Atomic Energy Commission, which didn’t work for an extended period. Later Bhutto provided A Q Khan full charge of the Kahuta Enrichment Project in July 1976. A Q khan built Engineering Research Laboratories (ERL) and developed the uranium enrichment plant. Later, on May 01, 1981, on the orders of Gen. Mohammad Zia ul-Haq, ERL was renamed as Dr. A.Q. Khan Research Laboratories (KRL). Ultimately this uranium enrichment led to the successful testing of Pakistan’sPakistan’s first nuclear device.

Significant Achievements

Dr. Abdul Qadeer Khan has served in science and technology in several remarkable ways, he published more than 188 scientific research papers in international journals. The significant process was made in uranium enrichment with the successful test-firing of Intermediate-Range Ballistic Missiles, Ghauri 1, in April 1998 and Ghauri II in April 1999, respectively.

For his marvelous contributions, Dr. Khan received the honorary award of Nishan-i-Imtiaz and Hilal-i-Imtiaz.
For his marvelous contributions, Dr. Khan received the honorary award of Nishan-i-Imtiaz and Hilal-i-Imtiaz.

Dr. A Q Khan was also the founder of the Ghulam Ishaq Khan Institute of Engineering Sciences and Tech in Topi, Swat. He was awarded the prestigious degree of doctor of science from the University of Karachi in 1993, from Baqai Medical University in 1998, Doctor of Science from Hamdard University, Karachi in1999, and from the University of Engineering and Technology, Lahore in December 2000. For his marvelous contributions, he received the honorary award of Nishan-i-Imtiaz and Hilal-i-Imtiaz.

In November 2003, the UN’s International Atomic Energy Agency warned the government of Pakistan of possible nuclear leaks. Khan was suspected of playing a significant role in this transfer of information regarding nuclear technology to other counties.

On January 31, 2004, he was arrested for his involvement in nuclear proliferation. Initially, he denied the accusation. Still, on February 4, he made an appearance on the Pakistani television and took the complete responsibility of his actions and exonerated Pakistan military and government from this scandal that rose a lot of questions later. He was held house arrest until 2009.
Despite being a controversial figure, he is still hailed by the masses as the national hero and pride of Pakistan.
