How NASA plans to bring back samples from Mars
Washington, Dec 11 (IANS) NASA has revealed how it plans to bring back Martian samples to Earth for the first time with the help of its next rover mission to the Red Planet, Mars 2020.
After landing on Mars, a drill will capture rock cores, while a caching system with a miniature robotic arm will seal up these samples. Then, they will be deposited on the Martian surface for possible pickup by a future mission, NASA said.
“Whether life ever existed beyond Earth is one of the grand questions humans seek to answer,” said Ken Farley of NASA’s Jet Propulsion Laboratory in Pasadena, California.
“What we learn from the samples collected during this mission has the potential to address whether we’re alone in the universe,” Farley said.
Mars 2020 relies heavily on the system designs and spare hardware previously created for Mars Science Laboratory’s Curiosity rover, which landed in 2012.
Despite its similarities to Mars Science Laboratory, the new mission has very different goals – it will seek signs of ancient life by studying the terrain that is now inhospitable, but once held flowing rivers and lakes, more than 3.5 billion years ago.
To achieve these new goals, the rover has a suite of cutting-edge science instruments.
It will seek out biosignatures on a microbial scale.
An X-ray spectrometer will target spots as small as a grain of table salt, while an ultraviolet laser will detect the “glow” from excited rings of carbon atoms.
A ground-penetrating radar will look under the surface of Mars, mapping layers of rock, water and ice up to 10 metres deep, depending on the material.
The rover is getting some upgraded Curiosity hardware, including colour cameras, a zoom lens and a laser that can vaporise rocks and soil to analyse their chemistry, NASA said.
The mission will also undertake a marathon sample hunt.
The rover team will try to drill at least 20 rock cores, and possibly as many as 30 or 40, for possible future return to Earth, NASA said.
Site selection has been another milestone for the mission. In February, the science community narrowed the list of potential landing sites from eight to three.
All three sites have rich geology and may potentially harbour signs of past microbial life. But a final landing site decision is still more than a year away.
“In the coming years, the 2020 science team will be weighing the advantages and disadvantages of each of these sites,” Farley said.
“It is by far the most important decision we have ahead of us,” Farley said.
The mission is set to launch in July/August 2020.

The mission focuses on helping families of terminally ill patients in hospitals by providing food and shelter. It also works to fulfill essential needs like education, jobs, and care for the elderly.
For the last 16 years, the Vijay Sri Foundation has been providing free services, benefiting thousands of people. Vishal Singh highlighted that the mission aims to gain global recognition like other organizations such as WHO, WWF, and Red Cross, which work for social causes.
During this meeting, Vishal Singh was appointed as the Chairman of the Hunger Free World Mission by representatives from various countries. They also discussed holding regular meetings in different countries to push the mission forward.
Business tycoon Dr. Abhishek Verma has also supported this humanitarian mission, vowing to promote the idea of “Seva Parmo Dharma” (Service is the highest duty) worldwide. Vishal Singh praised him, stating that people like Dr .Abhishek Verma inspire others to work for the betterment of society.
Recently, Romania’s Ambassador, Mr . Daniela Sezonov Ţane, invited Vishal Singh to the Romanian Embassy in Delhi, where they discussed the mission in detail. Impressed by his humanitarian work, she honored Vishal Singh and invited him to Romania to take the mission forward .
Food man Vishal Singh has been serving the people of India for the past 16 years. Through the Vijay Sri Foundation, he provides free meals to cancer patients & their families ,shelter, and education for women & children along with running free old-age homes in Lucknow.
In addition to his humanitarian work, Vishal Singh also addresses issues like crime and corruption through his role as Chairman of Seva Path Media and Managing Director of Vijay Sri Foundation.
During the COVID-19 pandemic, Vishal Singh and his team worked tirelessly to provide food and help to the needy, including starving children, elderly citizens, and pregnant women. Despite contracting the virus himself, he continued to assist others after his recovery. He even created a life-saving oxygen regulator using household items, which was praised by doctors both in India and abroad.
In his address at the meeting, Vishal Singh spoke about his mission to create a hunger-free world. He pointed out that India’s large population, along with issues like unemployment and poverty, has caused the country to fall on the Hunger Index. He urged people to contribute just one handful of grains daily to help create a hunger-free world.
He concluded by saying that through social participation, we can empower the people around us, meet their basic needs, and work together to build a stronger, more prosperous, and developed society.
