After Chandrayaan-2, the ISRO has planned launch of its solar mission, Aditya-L1, in the first half of 2020 to study the Sun’s corona, according to the space agency.

Aditya-L1 is meant to observe the corona, which are the outer layers of the Sun, extending to thousands of kilometers.

India on Monday successfully launched its second lunar mission Chandrayaan-2 onboard its powerful rocket GSLV-MkIII-M1 from the spaceport here to explore the unchartered south pole of the celestial body by landing a rover.

In a news conference last month, Indian Space Research Organisation (ISRO) K Sivan had said, “It is 1.5 million kilometres from the Earth. It will always look at the Sun and give analysis of the corona because it has a major impact on climate change.”

He said the mission is planned for launch in the first half of 2020.

Another interplanetary mission to Venus will be launched in the next 2-3 years, Sivan, who is also the secretary, Department of Space, had said.

Aditya-L1, with additional experiments, can provide observations of the Sun’s photosphere, chromosphere and corona.

In addition, particle payloads will study the particle flux emanating from the Sun, it added.

These payloads have to be placed outside the interference from the Earth’s magnetic field and cannot be useful in the low earth orbit, the ISRO added.

San Francisco: Facebook has added a new login feature that will notify users whenever they log into a third-party app or website using their account.

This login notification will alert the user every time a third-party application will access user data and will be sent via mail, zdnet.com reported on Wednesday.

“The design and content of the Login Notifications remind users that they have full control over the information they share with third party apps, with a clear path to edit those settings,” the report quoted Puxuan Qi, a Software Engineer Facebook.

This notification will show what kind of information the Facebook user has shared with the third-party application.

After receiving a notification, the user can click on the edit settings button to remove the app’s access to personal information.

The notification will help users detect unlicensed access or use of their credentials, but will also help educate them about the data they’re sharing with these apps.

The feature is already live and Qi said Facebook will continue to improve it throughout the year.
