New Horizon – Journey to Pluto



On July 4, 2015, a NASA spacecraft called New Horizons was 5 billion kilometers away from Earth. It was only 10 days away from Pluto, after flying for 9.5 years, when it suddenly dropped out of contact.  But let’s back up a little.

As of 1989, mankind had successfully sent a craft to every known planet in the solar system except one—Pluto. You may have heard that astronomers don’t consider Pluto or its brethren to be planets. However, most planetary scientists still do, which is why we’re using that terminology here. There’s a limited amount we can learn about Pluto from Earth because it’s so far from us.

Pluto, however, is a scientific goldmine. It’s located in a region called the Kuiper Belt, home to many small planets, hundreds of thousands of ancient icy objects, and trillions of comets. This mysterious region holds clues to the  formation of our solar system, and it was long, tantalizingly beyond our reach.

New Horizon

Until New Horizons. Its objectives were to explore Pluto, collect as much scientific data as possible, transmit it back to Earth, then explore farther out in the Kuiper Belt. To achieve this, the New Horizons team outfitted their craft with even state-of-the-art scientific instruments. Those included Ralph, a set of cameras powerful enough to capture features the size of city blocks in Manhattan from tens of thousands of kilometers away. And REX, designed to use radio waves to measure Pluto’s atmospheric pressure and temperature. All of the onboard equipment had to be built to be both reliable and lightweight because New Horizons had an additional challenge; it had to reach its target as fast as possible. Why?

Around 2020, Pluto will reach a point in its orbit where its atmosphere could freeze. And due to the tilt of its axis, more and more of Pluto’s surface is shrouded in darkness every year. Pluto completes a full orbit once every 248 Earth years, so it would be a long wait for the next prime opportunity to visit. To see how New Horizons got to Pluto in time, let’s jump to its launch.

The launch of New Horizon

Its three rocket stages accelerated New Horizons to such great speeds that it crossed the 400,000 kilometers to the moon in just nine hours. About a year later, the craft reached Jupiter and got what’s called a gravity assist. That’s where it flies close enough to the gas giant to receive a gravitational slingshot effect. New Horizons was then flying at around 50,000 kilometers per hour, as it would for the next eight years to cross the remaining gulf to Pluto. Going at such an astonishing speed meant that slowing down to get into orbit or land would’ve been impossible. That’s why New Horizons was on a flyby mission, where it would get just one chance to scream by Pluto and make its observations. The flyby would have to be fully automated since, at that distance, any signals to guide it from Earth would take 4.5 hours to reach it. So the team loaded the ship’s computer with a series of thousands of commands, called the core load, that would begin to execute when the craft was 6.5 days from Pluto.

But when New Horizons was just ten days out, disaster almost struck. Ground control lost contact with the spacecraft. After two nerve-wracking hours, New Horizons came back online, but mission control discovered that its main computer had rebooted, losing the entire core load and other critical data. Without that, it would soon whizz by Pluto with virtually nothing to show for the mission. Alice Bowman, the mission’s Operations Manager, led a team for 72 sleepless hours to get the instructions loaded back into New Horizons in time. Without room for a single error, she and her team pulled it off, and New Horizons began taking and broadcasting breathtaking images.

Those observations have revealed a delightfully varied world, with ground fogs, high altitude hazes, possible clouds, canyons, towering mountains, faults, craters, polar caps, glaciers, apparent dune fields, suspected ice volcanoes, evidence for past flowing liquids, and more. One of the most exciting discoveries is the 1000-kilometer-wide Sputnik Planitia glacier.

Sputnik Planitia Glaciers

Sputnik Planitia is mainly composed of slowly churning frozen nitrogen, and we’ve never seen anything like it in our solar system. It is around 1050 by 800 kilometers of patch full of ice. It is assumed that it was created by an impact basin which helped in collet all the ice and makes those glacials.

The exploration of Pluto was a great success, but New Horizons isn’t done yet. On January 1, 2019, it’ll break its own record for the furthest explored object when it visits a Kuiper Belt Object called 2014 MU69, which is orbiting the sun another billion kilometers farther away than Pluto. The world is holding its breath to see what it’ll find there.

Beginning of Apollo Space Program



In the shadow of the atomic bomb, science and politics became entwined. And as World War II progressed, countries began to capitalize on the power of technology. This shift in wartime strategy gave way to rapid advancements in weaponry like the development of the world’s first long-range, self-guided ballistic missile. And unlike those before it, this rocket had the potential to go to space and its creation would ultimately lead to a man on the moon. In the final years of the war, Nazi scientists successfully tested the V-2 rocket, the world’s most sophisticated missile and the first man-made object to cross the Karman line which is commonly represented as the start of space. When the war ended in 1945, the new world powers were dead set on acquiring the Nazi’s V-2 technology. This man, Wernher von Braun, was known as the brains behind the rocket.

He, along with other Nazi scientists, surrendered to the Americans and were transported to the US under a top secret project known as “Operation Paperclip”. The Germans were put to work, helping American scientists design and build military missiles that would ultimately be used in the beginnings of the space program. Meanwhile, Soviet scientists were repurposing the remains of Nazi rockets, and they were working much faster than the Americans. By the mid-1950s, the USSR developed an intercontinental ballistic missile equipped with a multi-stage design and multi-engine propulsion system making it capable of reaching orbit. On October 4th, 1957, the Soviet Union used its new missile to launch the first artificial satellite into space. The satellite known as Sputnik sent a wave of paranoia over the United States. Its Cold War enemy now had a vantage point from space, increasing the fear of a nuclear attack.

 The Space Race had officially begun. The US quickly tried to match the Soviet’s success by launching the Vanguard satellite. But the rocket only made it about a meter off the ground before its embarrassing explosion, earning the nickname, “flopnik”. Now in full Sputnik crisis mode, the government shifted its priority to the space race. President Dwight D. Eisenhower accelerated the 1958 launch of Explorer 1 – the first US satellite to reach space and established the National Aeronautics and Space Administration. Within eleven days, NASA launched its first spacecraft and within six months it announced the United States’ first man-in-space program.

Project Mercury had three objectives:

1. orbit a manned spacecraft around Earth
2. Investigate man’s ability to function in space

3. recover both man and spacecraft safely.

In the late 1950s, these were seemingly improbable tasks considering this was all happening around the same time the first computer hard disk was used, the electric printer was invented. Needless to say, technology had a long way to go. On top of that, NASA’s first astronauts had never actually been to space. They did, however, meet all the other necessary qualifications for a job that hadn’t been done before. The candidates were all military pilots, were highly educated and physically fit and they were the right height and weight to squeeze into the one-man Mercury spacecraft. The seven astronauts chosen for Project Mercury were painted as American heroes. And for a country inundated with a fear of nuclear attack, they provided much-needed hope and distraction. After a series of errors, tests and a brave chimp named HAM, in May 1961 astronaut Alan Shepard became the second human in space. The US came up short… again. Less than one month earlier, Russian Astronaut, Yuri Gagarin became the first man to complete an orbital mission. But the trajectory of the Space Race was about to change.

NASA President said, “I believe that this nation should commit itself to achieve the goal before this decade is out of landing a man on the moon and returning him safely to the Earth.” Under pressure to catch up to the Soviet Union at the height of the Cold War, President John F. Kennedy set an ambitious deadline. And from that moment forward, NASA’s human spaceflight efforts were guided by a single goal. NASA’s second man in space program acted as a bridge to the moon.

Project Gemini had four main objectives:

1. test an astronaut’s ability to fly long-duration missions

2. understand how spacecraft could rendezvous and dock in orbit

3. perfect re-entry and landing methods

4. further understand the effects of long space flight on astronauts.


All the while, Project Mercury was achieving major milestones. And on February 20, 1962, astronaut John Glenn became the first American to orbit Earth. By 1965, the first crewed Gemini mission took flight. The missions to follow set a series of firsts not just for the United States but for the world.
A new race was on for the United States. But now it was a race against time. In under five years, NASA needed to land a man on the moon. The Apollo Program would become one of the country’s biggest challenges, costing billions of dollars and risking dozens of lives. But if the decades of war and innovation leading up to this moment proved anything, it was that some of the biggest breakthroughs unfold when pressure is at its highest. And, just like challenges before it, Apollo would redefine the boundaries of possibility, taking humanity on a ride to an entirely new world.

This was how the Apollo program started. Stay tuned to know about the Apollo 11. Turn on the notification to get reminded.

CIMON – AI Robot onboard at ISS



Early morning on Friday, SpaceX has launched its 15th cargo shipment to the International Space Station (ISS) on its Falcon 9 rocket. This supplies included food and water for the six astronauts at the ISS and also an AI-powered robot which is to be a ‘crew member’ at ISS.

This robot is named as CIMON which stands for Crew Interactive Mobile Companion. Taking a look at this AI robot, it is designed like a volleyball which has a computer screen on it. This screen displays a cartoon face which will be helpful in interaction with the astronauts. CIMON includes 14 fans in it which will function to take the air of space station in and expelled it to move in the direction it wants. And it is due to this propeller like fans that CIMON will be able to float or levitate in the space station.


CIMON is combinedly developed by IBM and Airbus to be used in Germany’s national space station and aims to see that can AI robots and astronauts can cooperate in the space station to make their living easy. Before sending CIMON on board to ISS it has been tested in a parabolic flight which is like an airplane which moves in a particular path to create moments of weightlessness. CIMON is also trained with onboard ISS astronaut Alexender Gerst many times which will help AI robot in identifying his face and voice more effectively. Moreover, according to makers, CIMON can easily interact with all the astronauts easily without any hassle.

Once CIMON is onboard at ISS, Gerst will be taking help of CIMON for a couple of science experiments as a guide by displaying pictures and videos related to it. CIMON can be asked questions related to experiments. For now, CIMON is just meant to test the AI companion technology and for this reasons, CIMON will be interacting with the crew for just three hours.

Alongside CIMON, theirs also an instrument send to ISS which will help in monitoring the temperature of plants on Earth once attached outside the space station. This instrument will help us in monitoring the stress level of plants and also their water requirement fulfillment. Also, there will be a latching arm mechanism which will be attached to Canada’s robotic arm.


For this mission, SpaceX is using Falcon 9 rocket and Dragon. This will be the third time when SpaceX is using the refurbished Falcon 9 and Dragon. The dragon was last used in July 2016 and Falcon 9 was used in April this year. For SpaceX, it will be a record that it is able to make Falcon 9 ready for flight in just two and a half month after it was landed on one of the companies drone ships. This is will if the last flight for Falcon 9 Block 4, after this it will be replaced by a much powerful Falcon 9 Block 5 rocket which is even more efficient at launching, landing and reusing.

SpaceX has scheduled the launch of Falcon 9 Cape Canaveral Air Force Station in Florida at 5:42 AM ET on Friday and Dragon will be set out for space station after three days on Monday at 7 AM ET. If the weather conditions are not favored for the launch on Friday, the backup launch is scheduled on Sunday at 4:54 AM ET.

NASA’s live stream for this launch will start at 5:15 AM ET on Friday while that of SpaceX’s broadcast will start before 20 minutes of launch.
