NASA’s Opportunity rover’s science operations have been temporarily suspended as it waits out a growing dust storm on Mars, the US space agency said in a statement.

First detected by NASA on June 1, the storm ballooned to more than 18 million square.km and included the Opportunity’s current location at Perseverance Valley in the Red Planet by June 8.


The swirling dust has raised the atmospheric opacity, or “tau”, — the veil of dust blowing around, which can blot out sunlight — in the valley in the past few days.

As the rover uses solar panels to provide power and to recharge its batteries, the rover was required to shift to minimal operations.

The storm’s atmospheric opacity is now much worse than a 2007 storm that Opportunity weathered. The previous storm had an opacity level, or tau, somewhere above 5.5; this new storm had an estimated tau of 10.8 as of morning on June 10.

Despite the worsening dust storm, Opportunity also sent a transmission to NASA engineers on the same day, the report said.

Data from the transmission let engineers know the rover still has enough battery charge to communicate with ground controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California.

However, still science operations remain suspended, the report said.

Opportunity’s team has also requested additional communications coverage from NASA’s Deep Space Network — a global system of antennas that talks to all the agency’s deep space probes.

The latest data transmission showed the rover’s temperature to be about minus 20 degrees Fahrenheit (minus 29 degrees Celsius).

Engineers will monitor the rover’s power levels closely in the week to come. The rover needs to balance low levels of charge in its battery with sub-freezing temperatures.

Its heaters are vitally important to keeping it alive, but also draw more power from the battery. Likewise, performing certain actions draws on battery power, but can actually expel energy and raise the rover’s temperature.

The rover has proved hardier than expected by lasting nearly 15 years, despite being designed for a 90-day mission.

Full dust storms though one are not surprising, but are infrequent. They can crop up suddenly but last weeks, even months.

During southern summer, sunlight warms dust particles, lifting them higher into the atmosphere and creating more wind.

According to the World Health Organization, in 2020 itself, there were 2.3 million women diagnosed with breast cancer in the world.

Over the last one-and-a-half-year, people have been vocal about both mental and physical health in relationships. Even while miles away from one another, people kept checking on the health and well-being of their loved ones. However, one issue, i.e., breast cancer has been affecting women throughout the world, and it still needs much more focus and attention.

According to the World Health Organization, in 2020 itself, there were 2.3 million women diagnosed with breast cancer in the world. A report published by National Cancer Registry Programme (NCRP) estimates that breast cancer cases are likely to increase by nearly 20 per cent. Throughout the world, the tenth month of the year is recognized as the month of "Pink October" to raise awareness about breast cancer. The month should also be a celebration of encouraging the women in our lives to take the first step in this journey of staying in "Pink of Health". happen, an international dating app, conducted an in-app survey to understand how Indians discuss health issues like breast cancer with their partners. The survey gave a glimpse of whether health issues are impacting the life and relationships of singles.

41 per cent of users are not aware of examinations related to women's health


Forty-one per cent of users shared that they did not encourage the women in their life (mother, sister, friend, etc.) to go for checkups for issues related to health. Sixteen per cent of the respondents confessed that they did not remind women in their life to take examinations for their own health. It is important to note that regular self-examination is likely to detect breast lumps early. One in eight women will develop breast cancer in her lifetime. If it is detected in time, it will be cured in nine out of 10 cases.

Saudi Aramco engineers and journalists look at the Hawiyah Natural Gas Liquids Recovery Plant, June 28, 2021, in Hawiyah, in the Eastern Province of Saudi Arabia.

One of the world's largest oil producers, Saudi Arabia, announced Saturday it aims to reach "net zero" greenhouse gas emissions by 2060, joining more than 100 countries in a global effort to try and curb man-made climate change.

The announcement, made by Crown Prince Mohammed bin Salman in brief scripted remarks at the start of the kingdom's first-ever Saudi Green Initiative Forum, was timed to make a splash a little more than a week before the start of the global COP26 climate conference being held in Glasgow, Scotland.

Apple's App Store app is seen on a smartphone in Baltimore, March 19, 2018.

Apple has updated its App Store rules to allow developers to contact users directly about payments, a concession in a legal settlement with companies challenging its tightly controlled marketplace.

According to App Store rules updated Friday, developers can now contact consumers directly about alternate payment methods, bypassing Apple's commission of 15 or 30%.
