Today, we remember Robert H. Goddard as the “father of modern rocketry”, yet during his lifetime he was mockingly called “the moon man”. The scientific breakthroughs carried out by Goddard in rocket engineering have often been compared and to the Wright Brothers’ first flight in terms of significance in their respective fields.

Robert H. Goddard was an American scientist and engineer who dedicated his life to rocketry to make space travel a reality, unfortunately, it could not possible within his lifetime but thereafter and now we are living in an era of space tourism. After successful modeling he experimented in his research lab and came to a conclusion that without air to push, the thrust and the resulting propulsion can happen in a vacuum, by the time, this was considered nearly impossible. Additionally, it provided hope for space-flight that a rocket would be able to propel itself in space (space is also a vacuum). He also pondered on the practical nature of rocket propulsion to reach the moon. A relatively new and unique concept that was unheard of before, that resulted in an outburst of mockery prevail even after his death.

Childhood

Robert H. Goddard was the only child of Fannie Louise Hoyt and Nahum Danford Goddard. He was born on October 5, 1882, in Worcester, Massachusetts. Throughout his childhood, Goddard was always interested in science. Goddard’s father was supportive of his passion and helped by buying microscopes and telescopes for his son. He lived most of his childhood in the countryside, where he was free to explore. His love for physics led him to read all sorts of science-based books. It was such that in 1898 he read “War of the Worlds”, a space-fiction novel by H.G. Wells. This inspired him greatly and led him to ponder space exploration and the possibility of space-flight. On October 19, 1899, Goddard climbed a cherry tree with the intent to cut off the excess dead branches but became mesmerized by the sky. It was then that the thought hit him that “how wonderful it would be to make a device which had even the possibility of landing on the Moon?” Goddard penned down in his personal diary that he for the very first time he found his existence more reasoning”. From then on, Goddard dedicated the rest of his life to the field of rocketry and space exploration.

Likewise most of the genius of his time and hereafter, Goddard had always been a sickly and frail child. However, he quickly made up for the two worthy years of his life being lost and poured himself over books of mathematics and science. He excelled in his schoolwork, made class president twice and class valedictorian in high school. Once in a speech he memorizes his school days and said, “The dream of yesterday is the hope of today and the reality of tomorrow” which accurately represents his beliefs on space travel.

Academics & Professional life

Later on, Goddard spent his college years at Worcester Polytechnic Institute, in Worcester, Massachusetts and graduated in 1908. He got his Ph.D. in Physics from Clark University and joined it physics teacher. While experimenting in a less facilitated laboratory of Clark University, many breakthroughs such as thrust and propulsion can take place in a vacuum and the mathematical ratios of thrust and energy per different types of fuels were made. He started a series of small rocket experiments but being handicapped due to the lack of sufficient funding.

In September 1916, Goddard wrote a letter to Charles Greeley Abbot requesting funds from the Smithsonian Institution to continue rocket experiments. On January 5, 1917, his request was accepted and he was awarded $5000. Despite a series of sarcasm, criticism, and mockery the Institution continued funding for many years.

In the meanwhile, he met Charles A. Lindbergh who find his ideas more attractive and actually believed in the of space travel. Although Goddard tended to be very private with his research because of the public scorn he faced, he opened up to Lindbergh and shared his research. Lindbergh and Goddard shared a strong friendship based on their shared beliefs. Lindbergh helped Goddard procure a Guggenheim sponsorship for greater financial help in Goddard’s experiments.

Consequently, after receiving financial aid, Goddard moved to Roswell, New Mexico in 1930. Where he found large areas of land and also a peaceful atmosphere for his experiments. It was there that he opened a spaced outlet with a crew and did experimental flights. The locals were so respectful of Goddard’s privacy and did not interfere in his rocket experiments. In 1935 at Roswell, Goddard managed to be the first person to launch a rocket faster than the speed of sound.

It was around the time when World War II sat in and Goddard patriotically offered his expertise to the military. He was sure that he could create weapons but the military was not interested in the offer because they could not see a viable future in rocketry. However, the navy contacted Goddard asking him to aid them in building a powerful thrust booster to propel airplanes from the sea directly. Goddard agreed and moved to Annapolis, Maryland to work on its development.

Later, a German missile called V-2 discovered with a liquid-fueled motor similar to Goddard’s. When he happened to inspect that rocket, he quickly realized that they copied him. While the V-2 may not have been copied from Goddard’s design, his work certainly helped the Germans.

He was the first man to theorize and find the mathematical ratios of thrust and energy per different types of fuels. This was especially important as Goddard experimented with liquid fuels such as liquid oxygen and hydrogen. By then, these fuels were uncommon since rockets were fueled with powder. This discovery proved worthwhile. In 1914 Goddard patented his design for the first liquid-fueled rocket and after multiple trials and failure, Goddard had finally built a model of a liquid-fueled rocket. So, on March 16, 1926, in Auburn, Massachusetts on his Aunt Effie’s estate, he launched this rocket. Eventually, the rocket successfully achieved a short lift-off, becoming the first liquid-fueled rocket to take flight. The launch site is now an American national historic landmark, named as the Goddard Rocket Launching Site.

It was during this time in 1914 where he also patented his design for the multi-stage rocket, which had two or three stages using solid fuel. Additionally, his rocket flight in 1929 in which his rocket had a barometer and camera as a scientific payload was the first of its kind.

The New York Times Mockery

Goddard proposed that his rockets might travel through space and reach the moon as well as other planets. The New York Times responded to this with an editorial titled, “A Severe Strain on Credulity”. It thoroughly rejected the notion of space travel being possible to that extent. They believed that a rocket could not propel itself in the vacuum of space and claimed that Goddard “does not know the relation of action to reaction, and of the need to have something better than a vacuum against which to react against”. The editor went to the extent that a rocket traveling through space would, “deny a fundamental law of dynamics, and only Dr. Einstein and his chosen dozen, so few and fit, are licensed to do” and “Of course he [Goddard] only seems to lack the knowledge ladled out daily in highs schools”.

On July 17, 1969, the day after the launch of Apollo 11, 49 years after the editorial ridiculed Goddard, the Times published a retraction. It summarized the previous statements of “A Severe Strain on Credulity” and concluded by saying, “Further investigation and experimentation have confirmed the findings of Isaac Newton in the 17th Century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error” thus, admitting their mistake.

Goddard’s lagacy

Although Goddard was heavily ridiculed and mocked during his lifetime, he has received many awards and accolades after his death for his commendable work in rocket science. In 1959, he awarded the Congressional Gold Medal and on March 16, 1961, NASA opened the Goddard Space Flight Center in his honor that eventually caused a recognition to him, he really deserved to.

Robert H. Goddard once dreamt of an impossible and devoted his life for. Consequently, with hard work and sheer dedication, he proved that there is no limit what one can accomplish unless he limits his own thinking.

Scientists reveal the first-ever direct image of Black Hole

Scientists reveal 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 black hole 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 unveil 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.


The massive swirling clouds of dust and gas are rotating around the black hole at the speeds nearly approaching to that of light. The crescent-shaped appearance of the swirling disc is because the particles in the side of the disc are thrown towards earth faster and appear bright. The dark shadow within the disc is the “event horizon”― a point of singularity. Beyond this singularity point, there is no escape from the enormous gravitational pull of the supermassive black hole from which even the light cannot escape.
The research is also important because it tests the Einstein’s “theory of general relativity” which had predicted the presence of these massive sinkholes out there in the grand cosmos.

A Japanese spacecraft, Hayabusa-2, successfully blasts the surface of an asteroid named Ryugu, creating an artificial crater on the small world’s surface which scientists hope to snag. Japan’s space agency, JAXA, reported that the projectile, a two-kilogram copper cylinder, separated from the Hayabusa-2 spacecraft along with a camera known as DCAM3 to record this
“Small Carry-on Impactor” (SCI) operation. Hayabusa-2 flew to the far side of the Asteroid 162173 Ryugu, simply called Ryugu, to retreat from the debris that would be ejected when the projectile hit. “This is the world’s first collision experiment with an asteroid!” JAXA tweeted after the successful blast.

Hayabusa-2 was launched in 2014 and has been studying the 900 meters wide asteroid Ryugu up close since last June. The mission plan includes a touchdown of the spacecraft inside the crater to pick up a pinch of dust samples of the asteroid. In February this year, Hayabusa-2 had touched down on the asteroid’s surface and successfully collected the samples. But the second upcoming touchdown onto the asteroid, preceded by the latest blast on the surface will provide scientists with samples of subsurface dust which has not been exposed to sunlight or other space radiations for billions of years. Scientists hope to additional knowledge about the origin of inner planets, in particular the origin of water and organic compounds on earth, all relevant to the origin of life on earth.

The methane gas episodically wafts into the Mars’ atmosphere near the Martian equator.

A team of scientists working with the European Space Agency’s (ESA) Mars Express Orbiter has reported that methane gas episodically wafts into the Mars’ atmosphere within Gale crater, a 96-mile-wide crater near the Martian equator.

Mars Twin Rover

This notion once considered perplexing and bewildering is now widely accepted by scientists because NASA’s Curiosity Rover also measured a marked increase in methane gas around the same crater in 2013. However, quite mysteriously, the methane levels decreased within two months which was bewildering as according to the calculations, it would take a few hundred years for Martian atmosphere to breakdown methane molecules.

Mars methane mystery


Scientists are not sure if both, periodic increases and then subsequent decreases, are due to geological or biological processes. Two theories have been used to explain these findings: it might have been created by a geological process known as serpentinization, which requires both heat and liquid water. Or it could be a product of life — specifically methanogens, microbes that release methane as a waste product. Methanogens thrive in places lacking oxygen, such as rocks deep underground and the digestive tracts of animals.

Possible methane sources


The Mars Express findings also point to a possible source of the methane, about 300 miles east of Gale. In that region, ice must exist just below the surface. Dr. Giuranna, principal investigator for the Mars Express instrument that made the measurements, said: “methane could be released
episodically along faults that break through the permafrost due to partial melting of ice”. The findings are especially important as they can help direct future missions and serve as prime locations to search for signs of life.

India joined an elite club of countries with anti-satellite (ASAT) capabilities

India joined an elite club of countries with anti-satellite (ASAT) capabilities after ― USA, Russia, and China ― when it successfully destroyed one of its old satellite from a missile launched from the Abdul Kalam Island off the eastern coast of India. The March 27 test by India was not it’s first but a second attempt after a failed test on February 12, 2019. ASAT technology launches a missile from the surface which tracks and targets a satellite and destroys it with through collision.

GRAPHIC-INDIA-ANTI-SATELLITE-MISSILE

The capability can not only be used to neutralize old or useless satellites but can also be used to target satellites of any adversary, in case of a conflict, thereby crippling enemies’ missile and radar systems. However, the debris created by such a test remains in the earth’s orbit for days or even years (one-third of the debris in the space was created after China’s anti-satellite test in 2007) and poses a threat to hundreds of other satellites in earth’s orbit as well astronauts working on the International Space Station (ISS).

Different stages of anti satellite missile

NASA said that it had identified 400 pieces of orbital debris from that one event and the risk of small debris impacting ISS is above 44% over a period of 10 days. Jim Bridenstine, the NASA administrator, said: “that is a terrible terrible thing to create an event that sends debris in an apogee that goes above the international space station.” He also said that “We are charged with enabling more activities in space than we’ve ever seen before for the purpose of benefiting the human condition”. Referring to various experi-ments and research being done on ISS, he said “whether it’s pharmaceuticalss or printing human organs in 3-D to save lives here on Earth, or manufacturing capabilities in space that you’re not able to do in a gravity well, all of those are placed at risk when these kinds of events happen”

NASA’s 3-D Printed Habitat Challenge

Top three teams, competing in the latest level of NASA’s “3-D Printed Habitat Challenge”, have been awarded a share of $100,000.
Team SEArch+/Apis Corn, who won the first prize in the software modeling, presented a unique shaped habitat which is structurally designed to reinforce itself continuously and allows light to enter through trough-shaped ports on the sides and top. Zopherous won the second price and their design would be autonomously built by a roving printer.

3D-Printing

The roving printer would construct habitat one at a time and then move to the next site. Mars incubators came up with a model consisting of four volumes separated into functional zones which will provide a safe and robust environment for human life on earth.

The teams also made short interactive videos providing detailed insights into their designs and 3-D miniature models to showcase the interiors. The 3D-Printed Habitat Challenge is a competition to create sustainable shelters suitable for the Moon, Mars or beyond using resources available on-site in these locations. The multi-level 3D-Printed Habitat Challenge puts teams to the test in several areas of 3D-printing, including modeling software, material development, and construction. In addition to aiding human space exploration, technologies sought from this competition could also lead to lower-cost housing solutions on Earth and other benefits.

The winning team from Pui Ching Middle School, Macau, presented the idea of Zinc-air batteries, powered from reacting zinc and oxygen. These are not only rechargeable but also have low cost, safe and environment-friendly. But the reaction was carried out in the presence of platinum and palladium which are rare and expensive elements. The team has, therefore, replaced platinum and palladium with Metal-Organic Framework (MOF), a crystalline material composed of a 3D network of metal ions.

Sciencesteins, the runner up team, presented an idea for treatment of polluted water through nanorobots―tiny machines designed to perform a specific task at nano-dimensions. Another team, The Handy-Capable, worked on the challenge of clean and affordable energy: their idea was to place the piezoelectric plates (plates made from materials which accum-ulate electric charge in response to certain mechanical stress) before and after ticket barriers at train stations to power London streetlights.

The winners and runners up won trophies while all participants were given certificates and a Schools Science Competition mug.

NASA’s Spitzer Space Telescope revealed a beautiful red Butterfly Nebula

 

New images released by NASA’s Spitzer Space Telescope have revealed a beautiful red butterfly in space some 1,400 light years away from the sun. But actually it is not a butterfly, but a massive cloud of dust and gas, in shape of a butterfly, which serves as a nursery for hundreds of baby stars. Officially named Westerhout 40 (W40) the butterfly, is a nebula ― a giant cloud of gas and dust in space where new stars are born.

The butterfly’s two “wings” are giant bubbles of hot interstellar gas blowing from the hottest most massive region of stars. Inside the massive clouds of gas and dust, the force of gravity coalesces materials into dense clumps and clusters. Sometimes, when the clumps reach a critical density, stars are formed at the cores of these dense clumps. Radiations and winds spew out millions of tons of gas and dust out into space when those stars eventually explode and subsequently halts new star formation. The Infrared Array Camera (IRAC) on the Spitzer Space Telescope revealed that the red tinge of the W40 nebula is due to the presence of organic molecules of polycyclic aromatic hydrocarbons (PAH) in an excited state.

Some of the youngest stars are surrounded by dusty disks of materials, which glow with a yellow or red hue. The Spitzer Space Telescope is managed by Jet Propulsion Laboratory (JPL) in Pasadena, California while the Science Operations are conducted at Spitzer Science Center at Caltech in Pasadena.

 

All female spacewalk got canceled due to the shortage of outwear

Anne McClain and Christina Koch

The first ever all-female spacewalk, a historical leap for womankind, has been canceled for now due to lack of space-suit of the right size. The spacewalk, although, was not meant to be a historical moment and was scheduled as a routine to change the powerful lithium-ion batteries of the International Space Station (ISS). The significance of the original lineup for the Friday’s “extravehicular activity” (EVA) was recognized only after the schedule was discussed in a meeting, said NASA officials at Johnson Space Center in Houston.


The two astronauts, Anne C. McClain, and Christina H. Koch would both need to wear a medium-size torso―essentially the shirt of the spacesuit― component. Ms. McClain had thought that she would be able to work in a large sized torso, but after her spacewalk last Friday, she wore a medium-size torso and learned that it fit her better. Of the two medium-size torso only one is readily available at the International Space Station. The other one has yet to be configured properly for a spacewalk and could take hours. Instead of that NASA decided to simply switch out the astronauts. The mission itself is unchanged.

On Friday, Ms. Koch is still scheduled to participate, along with a fellow male astronaut Nick Hague. In the end, both women will have done a spacewalk ― just not together. The lithium-ion batteries being installed on this mission store solar energy when the space station, orbiting earth at a distance of 200 miles is not directly receiving sunlight.

Ultima Thule: A trans-Neptunian object at Kuiper belt

NASA’s spaceship New Horizon, launched in 2006, started its voyage with the aim to explore the uncharted territories beyond the solar system. On January 1, 2019, this spaceship threw a New Year gift to astronomy enthusiast across the globe when it flew-by close to a mysterious tiny rock revolving around the sun for billions of years in the dusk. The powerful cameras of New horizon captured closest images of the body, named as Ultima Thule – officially known as MU69. It is the farthest object visited by mankind.

It was reported on March 18th, 2019 at the Lunar and Planetary Science Conference that this double-lobed distant world caught by New Horizon space draft created in the early days of the solar system. That gentle crash, plus the Frankenstein body, suggests that planetesimals like Ultima Thule form from clouds of dust and rock clumping together under the force of their own gravity. Before New Horizons, it wasn’t clear if these proto-planets formed from cloud collapse or from small rocks slowly sticking together to form larger rocks over time.

The further new analyses by a team of researchers show that this tiny space rock formed from a rotating cloud of even smaller rocks that collapsed into two individual objects. Those objects then gently collided in the early days of the solar system. The first map of the space rock’s geology may help explain that flatness. The map shows distinct mounds on both lobes whose borders are still visible today.
