NASA has approved the Mars Sample Return (MSR) multi-mission effort to advance to the next phase in preparation to bring the first pristine samples from Mars back to Earth.

During this phase, the programme will mature critical technologies and make critical design decisions, as well as assess industry partnerships, NASA said on Friday.

The first endeavour of this campaign is in progress as the NASA's Mars 2020 Perseverance rover, launched in July, is set to land on the Red Planet February 18, 2021.

The car-size rover will search for signs of ancient microbial life.

Using a coring drill at the end of its robotic arm, Perseverance has the capability to gather samples of Martian rock and regolith (broken rock and dust), and hermetically seal them in collection tubes.

Perseverance can deposit these samples at designated locations on the Martian surface or store them internally.

In the next steps of the MSR campaign, NASA and the European Space Agency (ESA) will provide respective components for a Sample Retrieval Lander mission and an Earth Return Orbiter mission, with launches planned in the latter half of this decade.

The Sample Retrieval Lander mission will deliver a Sample Fetch Rover and Mars Ascent Vehicle to the surface of Mars.

The rover will retrieve the samples and transport them to the lander.

The Perseverance rover also provides a potential capability for delivery of collection tubes to the lander.

A robotic arm on the lander will transfer the samples into a container embedded in the nose of the Mars Ascent Vehicle.

Once sealed, the system will prepare for the first launch from another planet.

In Mars orbit, the Earth Return Orbiter will rendezvous with and capture the sealed sample container, and then place the samples in an additional high-reliability containment capsule for return to Earth in the early 2030s.

"Returning samples of Mars to Earth has been a goal of planetary scientists since the early days of the space age, and the successful completion of this MSR key decision point is an important next step in transforming this goal into reality," Thomas Zurbuchen, Associate Administrator for science at NASA Headquarters in Washington, said in a statement.

Bringing Mars samples back to Earth will allow scientists across the world to examine the specimens using sophisticated instruments too large and too complex to send to Mars, and will allow future generations to study them using technology not yet available.

Curating the samples on Earth will allow the science community to test new theories and models as they are developed, much as the Apollo samples returned from the Moon have done for decades.

The Mars Sample Return campaign also advances NASA's efforts to send humans to the Red Planet, NASA said.

When the ground violently shook beneath his feet, Prem Kishore Mohanty, an Indian expatriate in Bangkok, was attending his five-year-old daughter's school sports day. What began as a routine event—children competing, parents cheering—quickly turned into a moment of panic as tremors struck.

"I felt my head spinning and had to sit down. The overhead lights swayed, and chairs moved," said Mr. Mohanty, 44. The school's PA system quickly announced an emergency evacuation, directing everyone to the outdoor field while warning against using nearby lanes lined with high-rise towers.

Water from rooftop swimming pools, including those at the InterContinental Bangkok, cascaded down buildings, as captured in viral videos.

Fear and Chaos as Bangkok Shakes
The 7.7-magnitude earthquake, with its epicenter in Myanmar, sent powerful tremors into Thailand, bringing Bangkok to an abrupt standstill. Public transport was suspended, traffic snarled, and people evacuated buildings, waiting anxiously for the all-clear.

Earthquakes are rare in Bangkok, a city more accustomed to heat and monsoons than seismic shocks. For the Mohanty family, who live in a high-rise apartment in Sukhumvit, confusion and fear gripped them as the evacuation began.

"It was terrifying. We were told to take the fire escape stairwell and wait outside. There was no time to think," Mr. Mohanty recalled.

Now safe, he remains shaken by the unexpected jolt that turned a normal day into a moment of chaos for his family and thousands across the city.

In a country that brands itself the “Land of the Free,” pro-Palestine students are being treated like enemies of the state. The United States—once hailed as a beacon for academic freedom—is now using deportation threats, visa revocations, and AI surveillance to silence dissenting voices on its university campuses. What started as peaceful protest against the genocide in Gaza has turned into a full-scale purge of international students who dare to speak out. As global outrage grows, America's hypocrisy on free speech has never been more glaring—or dangerous.

Point-by-Point Summary:

•    Momodou Taal Forced Out:
British-Gambian activist and former Cornell PhD student Momodou Taal has left the U.S. after facing threats of deportation. His only “crime”: suing the Trump administration for policies targeting pro-Palestine students.

•    Bold Words from Exile:
Taal called out the U.S. for suppressing dissent and ignoring its own laws:
“Is imprisoning those who speak against genocide the kind of nation you want?”

•    300+ Visas Revoked:
Trump-era directives have led to mass deportations of foreign students who participated in or supported Gaza solidarity protests.

•    Rubio's Harsh Justification:
Secretary of State Marco Rubio defended the move, calling student protesters “lunatics” and stressing the government’s right to “remove you from our country.”

•    ACLU Slams Hypocrisy:
ACLU's Ben Wizner warned that the U.S. is now driving away the world’s brightest minds by criminalizing intellectual dissent.

•    Targeted Individuals:

•    Iranian student Alireza Doroudi arrested without cause.

•    Turkish student Rumeysa Ozturk lost her visa for an op-ed criticizing the Israeli regime.

•    Indian scholar Ranjani Srinivasan fled after agents showed up unannounced.

•    Korean resident Yunseo Chung, a green card holder, is still fighting deportation.

•    Professor Rasha Alawieh was deported despite holding a valid visa.

•    AI Used for Surveillance:
Reports confirm U.S. authorities are using artificial intelligence to flag students based on social media activity—even likes or shares.

•    Selective Freedom:
No pro-Israel lobbyist or supporter has faced deportation, even amid cases of inciting violence and harassment.

•    Global Consequences:
Calls to boycott U.S. universities are growing. The crackdown has undermined America’s status as a hub of academic freedom and global talent.

•    Final Warning:
The U.S. now risks not only its academic integrity but its moral standing. In defending a genocide abroad, it’s committing a slow-motion purge at home.

Mangaluru: A routine midnight tea run turned into a horrifying tragedy when a motorcycle carrying three young men — in clear violation of traffic rules — slammed into an open divider on National Highway 66 at SKS Junction in the early hours of April 8. Two of them lost their lives, while the third is recovering from injuries.

The victims have been identified as Sankeerth, who was riding the motorcycle (KL-58-Q-6381), and Dhanurved C, the first pillion rider. Sibi Sam, the second pillion rider, was injured but survived the crash.

According to the FIR registered at the Traffic East Police Station (Crime No. 48/2025), the friends had set out from Lohith Nagar around 2:30 am, heading towards Pumpwell for tea. While Rohan Joby and Meghnath rode separately on a different bike (KL-13-AH-2388), Sankeerth was accompanied by two pillion riders — a clear case of triple riding, which is both illegal and dangerous.

As they sped along NH-66, Sankeerth reportedly lost control near SKS Junction and collided with the edge of an open road divider at approximately 2:50 am. The impact threw all three men onto the highway with violent force.

Sankeerth and Dhanurved suffered critical head and facial injuries and died while being rushed to the hospital. Sibi Sam is undergoing treatment for his injuries.

The FIR invokes Sections 281, 125(a), 106(1) of the Bharatiya Nyaya Sanhita, and 128(a) read with 177 of the Motor Vehicles Act, which include provisions related to rash driving and traffic violations.

The police have launched a full investigation. The accident has reignited public concern about reckless driving, triple riding, and the hazards posed by poorly maintained road dividers, especially during low-visibility hours.
