It was in 1950s when mission to the moon caught the fancy of several countries. But in sometime they were abandoned. In fact, the moon itself became an abandoned planet, said M. Annadurai, former Director, U.R. Rao Satellite Centre (URSC), Indian Space Research Organisation (ISRO).

Lately, the moon is back into trend again. And this could be credited to India’s first moon mission Chandrayaan-1 in 2008 which found water molecules on the moon, Annadurai, who was the key man behind that mission, told IANS.


The former Soviet Union (now Russia) and the US had undertaken several moon missions since 1958.

However, it was the Soviet mission in September 1959 that succeeded first when its lunar impactor carried by its rocket Luna landed on the moon’s surface. The next month Russia followed it by a flyby mission.

After that, there were several failed attempts made by Russia and the US to land on the moon.

In July 1964, the US achieved success with its impactor landed on the moon surface. The spacecraft Ranger-7 was carried by its rocket Atlas LV-3 Agena B.

In 1966, Russia’s Luna-9 became the first spacecraft to land on the moon. The same year, the US made a successful landing with its lander on the moon.

The first crewed mission to the moon was by the US in December 1968. The spacecraft Apollo-8 orbited the moon and returned back to Earth.

The first human moon landing mission was launched by the US on July 16, 1969 with Neil Armstrong becoming the first man to step on the moon on July 21, 1969.

Later, Japan sent up its lunar mission in 1990, followed by the European Space Agency in 2003.

Asian giant China started its moon mission in 2007 with its orbiter. The country landed its rover on the moon in 2013. Earlier this year, China landed its spacecraft on the far side of the moon.

On its part, India began its moon mission on October 22, 2008 with its spacecraft Chandrayaan-1. The country also landed its Moon Impact Probe on November 14, 2008, thereby becoming the fourth country to have a touch down on the moon surface.

The most notable finding of the mission was the presence of water molecules on moon which in turn has revived the interest on moon missions. (IANS)

Surgeons attached a pig kidney to a pair of large blood vessels outside the body of a deceased recipient so they could observe it for two days, and the kidney did what it was supposed to do.

Scientists temporarily attached a pig's kidney to a human body and watched it begin to work, a small step in the decades-long quest to one day use animal organs for lifesaving transplants.

Pigs have been the most recent research focus to address the organ shortage, but among the hurdles: A sugar in pig cells, foreign to the human body, causes immediate organ rejection. The kidney for this experiment came from a gene-edited animal, engineered to eliminate that sugar and avoid an immune system attack.

Killer Smog in Delhi.

Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, a Decision Support System (DSS) that extends the ability of the existing air quality early warning system (AQEWS) to have decision-making capability for air quality management in Delhi-NCR was launched on Tuesday.

The website for the DSS (https://ews.tropmet.res.in/dss/) is designed to help the Commission for Air Quality Management for NCR and Adjoining Areas (CAQM) by delivering quantitative information about the contribution of emissions from Delhi and its 19 surrounding districts; the contribution of emissions from eight different sectors in Delhi; and the contribution from biomass-burning activities in the neighbouring states.

These information would assist in managing the air quality in a timely manner, a release from the Ministry of Earth Sciences said.

The need was stated by the CAQM, which was formed by the Ministry of Environment, Forest and Climate Change, during a meeting held in January 2021.

Recently, the Commission reviewed the progress made by IITM and had in principle approved the current version of DSS for air quality management in the Delhi-NCR. The IITM has also developed a new website for DSS with the entire system made operational, the release said.

Union Minister of State for Earth Sciences, Jitendra Singh, while launching the website for AQEWS on the occasion of 'Azadi Ka Amrit Mahotsav' week organised by the Ministry of Earth Sciences, said, "DSS is a significant contribution to 'Azadi Ka Amrit Mahotsav' on behalf of MoES and IITM and suggestions are invited on this issue."

The website also has a feature whereby the users can create their own emission reduction scenarios (from 20 different districts, including Delhi) so as to examine the possible projected improvement in air quality in Delhi for the next five days.

"This information would explicitly highlight the most important emission sources responsible for the degradation of air quality in Delhi and suggest possible solutions to ameliorate the same. With a plethora of quantitative data, the AQEWS integrated with DSS could become a user-friendly tool for air-quality management in and around Delhi," the release said. (IANS/JB)
