NASA will attempt to fly the Ingenuity mini-helicopter, currently attached to the belly of the Perseverance rover, on Mars on April 8, in the first such attempt on another planet.

However, before the 1.8- kg rotorcraft attempts its first controlled flight, both it and its team back home must meet a series of daunting milestones.

“When NASA’s Sojourner rover landed on Mars in 1997, it proved that roving the Red Planet was possible and completely redefined our approach to how we explore Mars. Similarly, we want to learn about the potential Ingenuity has for the future of scientific research,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters.

“Ingenuity is a technology demonstration that aims to be the first powered flight on another world and, if successful, could further expand our horizons and broaden the scope of what is possible with Mars exploration,” Glaze said in a statement on Wednesday.

On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing.

The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly.

Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign.

Flying in a controlled manner on Mars is far more difficult than flying on Earth.

The Red Planet has significant gravity (about one-third that of Earth’s) but its atmosphere is just 1 percent as dense as Earth’s at the surface.

During Martian daytime, the planet’s surface receives only about half the amount of solar energy that reaches Earth during its daytime, and night-time temperatures can drop as low as minus 90 degrees Celsius, which can freeze and crack unprotected electrical components.

To survive the frigid Martian nights, it must have enough energy to power internal heaters.

“Every step we have taken since this journey began six years ago has been uncharted territory in the history of aircraft,” said Bob Balaram, Mars Helicopter chief engineer at JPL.

“While getting deployed to the surface will be a big challenge, surviving that first night on Mars alone, without the rover protecting it and keeping it powered, will be an even bigger one,” Balaram added.

The helicopter deployment process will take about six sols (six days, four hours on Earth).

While Ingenuity will attempt the first powered, controlled flight on another planet, the first powered, controlled flight on Earth took place on December 17, 1903, on the windswept dunes of Kill Devil Hill, near Kitty Hawk, North Carolina.

Orville and Wilbur Wright covered 120 feet in 12 seconds during the first flight. The Wright brothers made four flights that day, each longer than the previous. (IANS/KB)

Between zoom meetings, webinars, you're walking a tight rope to balance work from home and domestic chores, in all this its easy to forget about taking care of yourself. It's imperative to squeeze in a few hours to indulge in yourself, whether its a massage or a hair spa treatment.

It comes with a range of accessories which includes the 40mm Airwrap long barrels, 30mm Airwra barrels, a Firm smoothing brush, a Soft smoothing brush, a Round volumising brush, the Pre-styling dryer, a non-slip heat-resistant mat to place your styler on, a Storage case and even a Filter cleaning brush. A Storage bag (Iron/Fuchsia) securely stores your Dyson Airwrap when you're on the move.

"The discovery of each new world provides a unique glimpse into the physics that play a role in planet formation," said lead author Jon Zink, a UCLA postdoctoral scholar.

An international team of astronomers has identified 366 new exoplanets, using data from the NASA Kepler Space Telescope's K2 mission. The findings, described in a paper published in the Astronomical Journal, showed a planetary system that comprises a star and at least two gas giant planets, each roughly the size of Saturn and located unusually close to one another.

The discovery is significant because it's rare to find gas giants -- like Saturn in the solar system -- as close to their host star as they were in this case. The researchers cannot yet explain why it occurred there, but it makes the finding especially useful because it could help scientists form a more accurate understanding of the parameters for how planets and planetary systems develop.

New moms can follow the given tips to take care of their little ones and protect them from the harmful effects of harsh winds blowing outside.

By Dr Anil Batra

The winter comes with its own set of hassles. New moms have to be careful because they have to take care of themselves and their babies. It becomes imperative to protect babies from the harsh season. The immune system of newborn babies is developing, which makes them susceptible to respiratory infections. But, you can take preventive measures to keep your child warm and safe. Newborn babies need extra care until their immune system becomes stronger to protect their bodies from the harmful effects of viruses and bacteria that usually become more active in the winter season. A drop in the temperature can aggravate different processes in the body, therefore, moms need to take extra care of newborn babies during winters.

New moms can follow the given tips to take care of their little ones and protect them from the harmful effects of harsh winds blowing outside.
