Washington: NASA is all set to test its low-density supersonic decelerator (LDSD) – a flying saucer designed to check out landing technologies for future Mars missions – over Hawaii.


If weather permits, the LDSD test vehicle will be carried aloft by a large weather balloon at 10 p.m. (Indian standard time) on Tuesday from the US Navy’s Pacific Missile Range Facility in Kauai, Hawaii.

For more than two hours, the balloon will carry the test vehicle to an altitude of 120,000 feet.

The tracking cameras NASA has employed for the test are expected to keep the balloon and test vehicle in their sights for about 30 minutes after launch, the US space agency said in a statement.

After reaching a height of 180,000 feet, a doughnut-shaped airbag will inflate around the saucer for its descent to earth.

The saucer is expected to splash down in the Pacific Ocean about two hours and 15 minutes after launch.

“The test is centred on how our newly-designed supersonic parachute will perform. We think we have a great design ready for the challenge, but the proof is in the pudding and the pudding will be made live for everyone to see,” said Mark Adler, project manager for LDSD at NASA’s Jet Propulsion Laboratory in Pasadena, California.

In order to support a human mission to the Red Planet, NASA needs technologies capable of landing between 20 to 30 metric tonnes on the Martian surface.

The LDSD supports payloads of two to three tonnes, doubling the current capabilities.

During the test flight, viewers will see live, low-resolution images from high over the Pacific Ocean off the west coast of Kauai, Hawaii.

Four cameras aboard the test vehicle will provide the LDSD mission team with different perspectives on the test.

The LDSD mission will test breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, and also will allow access to more of the planet’s surface by enabling landings at higher-altitude sites. (IANS)

Swastika, one of the sacred symbols used by many religions like Hinduism, Jainism, and Buddhism.

The symbol of Swastika is known to signify peace, prosperity, and good fortune in the religious cultures of Eurasia. In fact, this symbol is considered very significant in Hinduism, Buddhism, and Jainism. But, at the same time, it has become one of the most misunderstood religious symbols and has been globally banned in many countries.

The reason why the symbol of Swastika is banned in many countries is because of its association with Adolf Hitler's extreme political ideology, Nazism, as Swastika as its official symbol.

Since emerging into the public eye with a historic gold medal at the junior world championships in 2016, he has maintained a high level of performance

India celebrated a historic day on August 7, as 23-year-old Neeraj Chopra became the first Indian to win an Olympic gold medal in athletics. In the men's javelin throw event, he achieved his greatest triumph, throwing the javelin 87.58 meters on his second try.

Neeraj Chopra was born on December 24, 1997, in Khandra village in Haryana's Panipat district. He grew up in a Haryanavi family of farmers. He is the brother of two sisters. He graduated from Dayanand Anglo-Vedic College in Chandigarh and is now enrolled in Lovely Professional University in Jalandhar, Punjab, pursuing a Bachelor of Arts degree. Chopra was bullied due to his obesity as a kid, which prompted his father to enroll him in a nearby gym. He then joined a gym in Panipat, where Jaiveer Choudhary, a javelin thrower, noticed his potential and coached him. When the 13-year-old Chopra finished training under Jaiveer for a year, he was enrolled at the Tau Devi Lal Sports Complex in Panchkula, where he began training under coach Naseem Ahmed.

Gothic dresses displayed in a store

The emergence of the Industrial Revolution in Victorian England brought with it many apprehensions and fears that translated into a new genre in literature: the gothic. Today, the idea of the gothic does not have to much with literature as much as it is associated with fashion.

The Victorians began to wear black more often during the Industrial Revolution to hide the stains of soot on their clothes. Many of the working class were employed in factories. They were newly introduced to technology, the idea of coal as fuel, and the working of machines to serve a certain purpose. This kind of work was hard and messy. Wearing light colours burdened the tired folk when the stubborn stains did not get washed away.
