Hours after NASA dunked the news of asteroid hitting the earth, asteroid smashes in the Caribbean

The asteroid in question has been identified as the 2019 MO. It was shooting towards the earth at a speed of 14.9 km/sec and NASA didn’t know about it. NASA has admitted that when it came to know about the asteroid, it was too late to do anything about it. The width of the fireball has been approximated to be 16 feet. Luckily, because of its small size, the asteroid burned up in the atmosphere before reaching the earth’s surface. According to reports, the remnants of the asteroid broke up and scattered over the Caribbean.

In its defense, NASA has established that it had detected the asteroid but not taken any measures against it as it was sure the asteroid would do no harm. The space agency admitted that the rock was first spotted when it was 500,000 km from Earth, just before it hit the earth’s surface. To quote the agency-“ this was roughly equivalent of spotting something the size of gnat from a distance of 310 miles( 500 kilometers).

The asteroid entered the Caribbean in the evening of 22 June, and generated energy worth 3 to 5 thousand TNT, according to some astronomers.

NASA has also recently reported that on Friday, an asteroid roughly equivalent to the size of Eiffel tower would shoot past the earth. In July, it was reported that a mammoth space rock flew by “uncomfortable proximity” with the earth. Scientists feared that if it collided with the earth, it would be equal to the destruction caused by a very large nuclear weapon.

NASA’s shock claim reveals Apocalyptic risk of sudden meteor strike

Our Earth and a meteor is on a collision course and has the potential to be apocalyptic. This is not a fanatic speaking but claimed by NASA. It has issued a terrifying warning, proclaiming that the Earth is under threat of a meteor strike amid growing concerns of an imminent asteroid impact.

NASA’s chief scientist Jim Bridenstine issued one of the agency’s most alarming warnings yet – claiming that the Earth is “about to face its biggest threat from outer space”. His doom-laden remarks came during a conference organised to better equip humans with ways to defend the planet against a meteor strike.

This week scientists from around the world have been meeting at the 2019 Planetary Defense Conference in College Park, Maryland. The exercise has become a regular event among the international community of “planetary defense” experts.

This year, the conference has been scrambling to develop methods of combating imminent asteroid impact, as well as emergency evacuation plans.

Popular television scientist Bill Nye also warned about the existential threat to humanity during the conference.

He told reporters: “The Earth is going to get hit with another big asteroid. The problem is, we don’t know when. It’s a very low probability in anyone’s lifetime, but it’s a very high-consequence event. If it happens, it would be like control-alt-delete for everything.”

NASA Chief Scientist Jim Green echoed Bill Nye’s remarks: “It’s not a matter of if; it’s only a matter of when.”

During a role-playing simulation exercise, NASA scientists tried and failed to stop a meteor crashing into the earth – despite being given eight years to prepare in the simulation.

In this scenario, the meteor was heading for New York City, which was eventually forced to evacuate under the simulation scenario.

The asteroid blast destroyed everything within a 15 kilometer “unsurvivable” with an energy 1,000 greater than the nuclear bomb dropped on Hiroshima.

NASA is currently working with Elon Musk’s Space X company to develop a Double Asteroid Redirection Test in a bid to stop a future collision. It seems like they are the last hope for the earth’s survival if the threat proves to be true.

NASA claims that the Aluminium fraud caused satellite failures costing $700 Millions

0

A metals manufacturer faked test results and provided faulty materials to NASA, causing more than $700 million (roughly Rs. 4,900 crores) in losses and two failed satellite launch missions, according to an investigation by the US space agency.

The fraud involved an Oregon company called Sapa Profiles, which falsified thousands of certifications for aluminium parts over 19 years for hundreds of customers, including NASA.

The bad parts were used in the making of Taurus XL, a rocket that was supposed to deliver satellites studying the Earth’s climate during missions carried out in 2009 and 2011. The launch vehicle’s fairing, a clamshell structure that carries the satellite as it travels through the atmosphere, didn’t fully open, causing the unsuccessful launch, according to a statement from NASA.

News of the satellite failures comes a week after Norsk Hydro ASA, the current parent company of Sapa, agreed to pay $46 million to NASA, the Department of Defense and others to resolve criminal charges and civil claims related to the fraud, which took place from 1996 to 2015.

The company admitted that employees had faked test results related to the metal’s strength and reliability under pressure. Sapa Profiles, now known as Hydro Extrusion Portland, also agreed to plead guilty to one count of mail fraud and is barred from US federal government contracting.

A spokesman for Norsk Hydro said the case has been settled. Last week, it said it has invested “significant time and resources to completely overhaul our quality and compliance organisations.”

India’s Mission Shakti increased risk to International Space Station: NASA

0

Mission Shakti was a remarkable event in Indian History. India became only the 4th nation to unlock and prove the capability of Anti-Satellite weapons. But, this event increased the vulnerability of impact to International Space Station by 44%.

Speaking at a townhall on Monday, Bridenstine, NASA administrator, in a response to a question from a colleague, said that the risk to the ISS (due to possible collision with the space debris) had gone up by 44 per cent after the Indian anti-satellite test, though he added that both the ISS and the astronauts were safe.

“Here is what we know about the most recent direct ascent anti-satellite test done by India. We know that we have identified 400 pieces of orbital debris from that one event. That is what has been identified. Now, all of it cannot be tracked. What we are tracking right now, objects big enough to track and we are talking about objects 10 cm or bigger … about 60 pieces have been tracked. They have got tracking number… Out of those 60, we know that 24 of them are going above the apogee of ISS. That is a terrible terrible thing to create an event that creates debris that goes above the apogee of ISS,” Bridenstine said.

But he also said that the threat from the Indian test was much smaller compared to that created by a similar test by China in 2007, and that no harm was likely to be done to the ISS or the astronauts.

“The good thing is that it is low enough and over time this will all dissipate. You go back in time, 2007, (the) direct ascent anti-satellite test by the Chinese, a lot of the debris is still in the orbit,” he said.

The International Space Station, or ISS, is the world’s only permanent facility in space, and is always manned by one or more astronauts. The ISS serves as a platform to carry out a variety of experiments in space, especially those that require zero gravity, and also for testing new space systems and technologies.

Remembering Kalpana Chawla who dared to Rise

0

Kalpana Chawla was the first Indian-born woman to reach space, tragically died on 1st February 2003. She was the second Indian to fly in space after Rakesh Sharma. The Haryana-born astronaut died along with six others — just 16 minutes before landing as the Space Shuttle Columbia disintegrated over Texas during its re-entry into the Earth’s atmosphere.

Early Life and Education

Kalpana Chawla was born on 17th March 1962 in Karnal, Haryana.  She graduated from the Tagore School in 1976 and then went on to complete her bachelor’s in Aeronautical Engineering from the Punjab Engineering College in 1983. Later, she moved to the United States for higher studies. She completed her master’s in Aerospace Engineering in 1984 from the University of Texas at Arlington. After that, she moved to Boulder, Colorado in order to pursue a doctorate in aerospace engineering, which she completed in 1988.

After earning her doctorate, she started working at NASA, where she did computational fluid dynamics (CFD) research on vertical and/or short take-off and landing (V/STOL) concepts. She later became a naturalized U.S. citizen in 1991 and then applied for the NASA Astronaut Corps. She joined the corps in 1995 and then NASA selected for her first flight in 1996.

Space flights

Kalpana became the first Indian woman to reach space on November 17, 1997, when her first space mission began. She was a part of the six-astronaut crew who flew the Space Shuttle Columbia flight STS-87. On her first mission, Chawla traveled over 10.4 million miles (16737177.6 km) in 252 orbits of the earth, logging more than 372 hours (15 Days and 12 Hours) in space.

Kalpana was selected for her second flight in 2000. She became a part of the crew of STS-107. Due to various technical and scheduling conflicts, NASA had to delay the mission several times. Then on 16th January 2003, Kalpana’s mission was launched. The crew performed nearly 80 experiments which included studying earth and space science, advanced technology development, and astronaut health and safety.

The accident and tragic death of Kalpana

It all started during the launch of STS-107. It was Columbia’s 28th mission and a piece of foam insulation broke off from the Space Shuttle external tank and struck the left wing of the orbiter. NASA thought that it was a minor issue as previous launches had seen such incidents and everything went fine. Some engineers suspected that the damage is quite serious but it was too late as they reasoned that the crew could not have fixed the problem if it had been confirmed.

When Columbia re-entered the atmosphere of Earth, the damage allowed hot atmospheric gases to penetrate and destroy the internal wing structure. This caused instability of the spacecraft. The Spacecraft disintegrated into pieces resulting in the death for 7 crew members including our Kalpana Chawla.

After this incident, NASA suspended all its space operations for the next two years. She was made for the sky and she died in the sky. Though Kalpana died, we still remember her as the lady who dared to fly. She will keep inspiring the generations to come.

The Smiley in the New Galaxy

NASA’s Hubble Space Telescope has captured a formation of galaxies that looks like a smiling face. On Saturday, NASA posted an image on its Instagram handle that showed two yellow orbs above an arc of light — painting a smiley face in space. The image boasts an unprecedented resolutio of Hubble’s telescope. The American space agency Asked its followers to find the face. NASA explained that using unprecedented resolution of the Hubble’s camera it was able to locate and study regions of star formation. 

The arc of light is a galaxy whose shape has been distorted and stretched as a result of passing a massive gravity source, according to the NASA. 

The lower, arc-shaped galaxy has the characteristic shape of a galaxy that has been gravitationally lensed — its light has passed near a massive object en route to us, causing it to become distorted and stretched out of shape.

The smiling face is located in the galaxy cluster SDSS J0952+3434, and was shot with the Hubble Space Telescope’s Wide Field Camera 3 (WFC3). The Hubble telescope returned to normal operations on October 26 after successfully recovering a backup gyroscope replacing a failed in October. Hubble was set to last 15 years, but even after 28 years, it is active in making scientific discoveries.
