Signs of Water Found on Asteroid Bennu

NASA's OSIRIS-REx spacecraft has discovered ingredients for water on a relatively nearby skyscraper-sized asteroid, a rocky acorn-shaped object that may hold clues to the origins of life on Earth.
The probe, on a mission to return samples from the asteroid to Earth for study, was launched in 2016. Bennu, roughly a third of a mile wide, orbits the sun at roughly the same distance as Earth.
There is concern among scientists about the possibility of Bennu impacting Earth late in the 22nd century.

China to Uncover Moon's Dark Side

China launched a rover destined to land on the far side of the moon, a global first that would boost Beijing's ambitions to become a space superpower.
The Chang'e-4 lunar probe mission, named after the moon goddess in Chinese mythology, was launched on a Long March 3B rocket from the southwestern Xichang launch centre.
Chang'e-4 is humanity's first probe to land on and explore the far side of the moon.

First Vibration Sound on Mars

Humans can now hear the haunting, low rumble of wind on Mars for the first time, after NASA's InSight lander captured vibrations from the breeze on the Red Planet.
The strong gusts of wind, blowing between 10 to 15 mph (five to seven meters a second), were captured as they moved over the solar panels on InSight, an unmanned lander that touched down on Earth's dusty, desolate neighbour on November 26.

World's first Telerobotic Coronary Intervention

India became the first country to perform a telerobotic coronary surgery on human. The "first-in-human" telerobotic coronary intervention was performed by Padma Shree and noted cardiologist Dr. Tejal Patel on a middle-aged woman who had volunteered for the first experimental coronary stenting.
Gujarat Chief Minister Vijay Rupani was present at the console in the Akshardham Temple in Gandhinagar from where Dr. Patel with remote control was conducting the surgery on the patient 32 km away at Apex Heart Institute in Ahmedabad.
It took just 15 minutes to complete the telerobotic coronary intervention.

Womb Transplant from Dead Donor

As per reports, a woman in Brazil who received a womb transplanted from a deceased donor has given birth to a baby girl in the first successful case of its kind.
It comes after 10 previously known cases of uterus transplants from deceased donors, in the United States, the Czech Republic and Turkey, failed to produce a live birth.
Dani Ejzenberg, a doctor at Brazil's Sao Paulo University hospital who led the research, said that the transplant carried out in September 2016 when the recipient was 32, shows the technique is feasible and could offer women with uterine infertility access to a larger pool of potential donors.

Scientists Discover New Exoplanets

Scientists have discovered a cache over 100 new exoplanets using data from NASA's Kepler Space telescope as well as ground-based observatories.
The diverse planets are expected to play a large role in developing the research field of exoplanets and life in the universe.
Exoplanets, which revolve around stars other than the sun, have been actively researched in recent years.

India Launches Heaviest Satellite

India's heaviest satellite GSAT 11 was successfully launched by the European commercial launch provider Arianespace from Kourou space centre, French Guiana.
GSAT 11 is an advanced communication satellite. It is the largest and heaviest satellite built by ISRO. It will fulfil most needs of providing broadband connectivity to rural and inaccessible gram panchayats under the "BharatNet project."
The satellite is the third of the four satellites that will give high-speed broadband connectivity to all parts of India, bridging the rural and urban divide. Two satellites, the GSAT 19 and 29, have already been launched and the fourth GSAT 20 will be launched later next year.
