India's manned space mission in December 2021: ISRO

Bengaluru, Jan 11: India's maiden manned space mission 'Gaganyaan' is set for December 2021 launch and is likely to include a woman astronaut, Indian Space Research Organisation Chairman K Sivan said Friday.

Gearing up for the mission, announced by Prime Minister Narendra Modi, the ISRO has set up a new centre to facilitate the manned voyage involving a three-member crew, he said.

"We have put everything in place. Gaganyaan has highest priority for 2019. We are planning to have first unmanned mission in December 2020 and second for July 2021. Once we complete this the manned mission will happen in December 2021. The entire team is geared up to achieve this target," Sivan said.

The Union Cabinet gave its nod for the Rs 9,023 crore programme recently, he said, briefing reporters about the achievements of the city-headquartered ISRO in the previous year and the future programmes.

In his Independence Day address last year, Modi had announced that the mission would be undertaken by 2022 using ISRO's own capabilities.

"We have resolved that by 2022, when India celebrates 75 years of Independence or maybe even before that, certainly some of our young boys and girls will unfurl the Tricolour in space," he had said in his speech from the ramparts of the Red Fort 

To a question, the ISRO chief said, "We want women astronauts also should be there. That is our aim. In my opinion, we have to train both men and women. The PM has told brother and sister (boys and girls). We will be happy to do that... but it involves training and other things." 

He said a major expansion was in the offing with the launch of Gaganyaan.

"There are two aspects to Gaganyaan -- engineering and human. This is a major expansion because it is not only launching human into the space but a space station. Human programme is a major turning point," Sivan said.

He said the objective of the mission is to carry a three-member crew to low earth orbit and return them safely to a predefined destination on earth.

Sivan said ISRO had launched the Human Space Flight Centre to take care of all the things related to the manned space programme.

The centre will have senior scientist Unnikrishnan Nair as its director while the project director would be Dr R Hutton, the ISRO chief said.

He said the crew members for Gaganyaan would be from India and include one from the Indian Air Force.

Gaganyaan initial training will be in the country but advanced training might be abroad, maybe in Russia, Sivan said.

On successful completion of the mission, India would become the fourth nation in the world to achieve the feat, he said.

Paris, Jul 2: Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Universite).

The scientists analysed the star's motion and concluded that it hosted two planets, WASP-148b and WASP-148c. The observations showed that the two planets were strongly interacting, which was confirmed from other data.

Whereas the first planet, WASP-148b, orbits its star in nearly nine days, the second one, WASP-148c, takes four times longer. This ratio between the orbital periods implies that the WASP-148 system is close to resonance, meaning that there is enhanced gravitational interaction between the two planets. And it turns out that the astronomers did indeed detect variations in the orbital periods of the planets.

While a single planet, uninfluenced by a second one, would move with a constant period, WASP-148b and WASP-148c undergo acceleration and deceleration that provides evidence of their interaction.

The study will shortly be published in the journal Astronomy & Astrophysics.

Consumer watchdog Which? has claimed that more than one billion Android phones and tablets are vulnerable to hackers as they no longer supported by security updates.

According to the research report, the most at-risk phones are any that run Android 4 or older and those smartphones running Android 7.0 which can not be updated are also at risk.

Based on data from Google analysed by Which?, two in five android device users around the world are no longer receiving the important updates. Currently, those devices are unlikely to have issues, but the lack of security leaves them open to attack.

"It is very concerning that expensive Android devices have such a short shelf life before they lose security support, leaving millions of users at risk of serious consequences if they fall victim to hackers," Kate Bevan editor Which? said in a statement.

"Google and phone manufacturers need to be upfront about security updates with clear information about how long they will last and what customers should do when they run out. The government must also push ahead with planned legislation to ensure manufacturers are far more transparent about security updates for smart devices and their impact on consumers," Kate added.

Android phone released around 2012 or earlier, including popular models like the Samsung Galaxy S3 and Sony Xperia S, are particularly at risk to hackers.

Which? has made suggestions to Android users on what to consider if they have an older phone that may be at risk.

Any Android device which is more than two years old, check whether it can be updated to a newer version of the operating system. If it is on an earlier version than Android 7.0 Nougat, try to update via Settings> System>Advanced System update.

In case a user is not able tto update the phone, the device could be at risk of being hacked if it is running a version of Android 4 or lower.

A user also need to be careful about downloading apps outside the Google Play store and should also install a mobile anti-virus via an app.

The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.
