It’s been months since China’s Zhurong Mars rover entered a “hibernation” to wait out the cold and harsh winter on planet&nbsp;Mars’ northern hemisphere and its alien landscape. However, the slumber which was planned to end in December of last year still continues. Now the question is, will the rover ever wake up? There’s still hope.

What is Zhurong?

Zhurong is part of Tianwen 1, China’s ambitious Mars mission, and the nation’s first interplanetary mission. The mission, which includes a Mars rover, touched down on the Red Planet’s Utopian Planitia in May of the year 2021.

Why is a rover ‘sleeping’?&nbsp;

Following its landing, it conducted a range of scientific and exploration activities before retreating into a so-called hibernation or dormant state to survive the barren planet’s winter, during which, as per space.com, temperatures can fall down to minus 195 degrees Fahrenheit (minus 125 degrees Celsius).&nbsp;

It went to sleep on May 18 of last year.

What conditions are needed for it to wake up?

Talking to reporters in September 2022, Jia Yang, a Tianwen 1 mission deputy chief designer, revealed that Zhurong would wake up by itself when two conditions are met: it can generate energy greater than 140 watts and the planet’s temperature, or rather the region where the rover is, reaches the somewhat warmer, 5 degrees Fahrenheit (minus 15 degrees Celsius).

When was it supposed to rise up again?

Zhurong slumber was expected to end in December when the red planet experiences its spring equinox. However, this did not happen. So far, it’s just silence.

What went wrong?

As per a January 9 report by Space News, China’s first interplanetary mission may be in trouble “with the rover potentially lost on the surface after winter hibernation”. There is also speculation that maybe the temperatures just aren’t warm enough.

What is the temperature on Mars currently?

As per NASA’s Perseverance Rover, which is also wandering Mars’s surface, the temperature in the planet’s Jezero Crater has only briefly risen higher than Zhurong’s lowest heat requirement.&nbsp;

But given that Perseverance is nearer to the red planet’s equator - located around seven degrees latitude south of its Chinese counterpart - it may be experiencing slightly more favourable conditions than Zhurong.

How is Perseverance awake?

NASA's 2020 rover Perseverance, meanwhile, is not asleep. It is nuclear-powered and doesn’t need to hibernate.

What else could be plaguing the Chinese rover?

Zhurong generates its power using solar arrays. Mars is known for its sand storms and there is concern that the dust from them may be hindering the rover and its solar arrays’ ability to generate power.

While Zhurong’s panels are made using anti-dust material and it has a vibration setting to shake off the dust, even that feature requires some power. The rover has to be active to “shake it off”.

What now?

The rover's mission with which China achieved the status of being the second country to reach the surface of Mars is already a great success.

But only time can tell if it will wake up to achieve bigger and better things.

Explained | Zhurong's slumber continues for months. Has China's Mars rover fallen 'silent' forever?

The Giant Metrewave Radio Telescope (GMRT) which is located in India’s Pune, has detected a radio signal originating from an extremely distant galaxy.

Astronomers from McGill University in Canada and the Indian Institute of Science (IISc) are behind the detection of these signals.&nbsp;The findings have been published in the scientific journal Monthly Notices of the Royal Astronomical Society.&nbsp;

With the signal travelling across the largest astronomical distance to reach us, this discovery marks a historical point in humanity’s astronomical journey.

“The astronomical distance over which such a signal has been picked up is the largest so far by a large margin. This is also the first confirmed detection of strong lensing of 21 cm emission from a galaxy”, said the IISc in a statement.

The signal reportedly originated from the atomic hydrogen of an ‘extremely’ distant galaxy. As per IISc, atomic hydrogen is the basic fuel required for star formation in a galaxy.

As per the information available on the IISc website, “when hot ionised gas from the surrounding medium of a galaxy falls onto the galaxy, the gas cools and forms atomic hydrogen, which then becomes molecular hydrogen, and eventually leads to the formation of stars. Therefore, understanding the evolution of galaxies over cosmic time requires tracing the evolution of neutral gas at different cosmological epochs.”

The radio signal was reportedly extremely weak.

However, it is still significant due to the fact that it is nearly impossible to detect emissions from a distant galaxy using the technology which is currently available. The telescopes currently have limited sensitivity.

“Until now, the most distant galaxy detected using 21 cm emission was at redshift z=0.376, which corresponds to a look-back time – the time elapsed between detecting the signal and its original emission – of 4.1 billion years,” said IISc in its statement.

Here, ‘Redshift’ refers to the change in wavelength of the signal depending on the object’s location and movement. Furthermore, the greater the value of z, the farther the object is.

India-based telescope detects faint radio signal from an extremely distant galaxy

NASA’s largest and most powerful space science telescope, the James Webb Space Telescope (JWST) has made the groundbreaking discovery of a planet that is around 99 per cent the size of Earth. It is located in the constellation Otans, and is just 41 light years away from our home planet. The newly discovered exoplanet has formally been classified as LHS 475 b., and currently not much is known about its atmosphere and whether it is fit to be inhabited by humans. While researchers have ruled out a thick methane-dominated atmosphere similar to that of Saturn’s moon Titan, they say that atmospheric compositions like a pure carbon dioxide atmosphere have not been ruled out.

The newly discovered space object has been classified as an exoplanet as it orbits another star and is terrestrial, i.e., it is a rocky planet, composed primarily of silicate rocks or metals. As per a Daily Mail report, it completes the orbit in two days.

IANS reports that the planet is a few hundred degrees warmer than Earth.

As per the team behind this discovery, the James Webb telescope has proven just how powerful its technology is. Talking to the press, Mark Clampin, Astrophysics Division director at NASA Headquarters in Washington, DC, said that the find opens the door “to many future possibilities for studying rocky planet atmospheres with Webb.”

He remarked that the telescope “is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started.”&nbsp;
