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.

A day after National Commission for Women said no woman from Hassan approached the national body to file complaints against Karnataka MP Prajwal Revanna, a new FIR accusing BJP leader Devaraje Gowda of abusing and assaulting a woman has come to light.

The FIR against Gowda was filed by a woman at the Holenarasipura town police station on April 1, after her husband had filed a complaint against the BJP leader on March 30. 

The purported victim's husband has alleged in his plaint that Gowda barged into their home, and threatened the couple while the BJP leader also abused the woman.

Gowda, notably, flagged Prajwal Revanna's case to the saffron party.

Reacting to the allegations levelled against him, the BJP politico posted a video on Facebook where he details how he met the woman and her husband in his office. He also claims that the allegations against him are a plot and false.

It must be noted here that a Special Investigation Team is currently probing the sexual assault cases against Prajwal Revanna who along with his driver Karthik is no longer in the country. A Blue Corner notice is also in place to apprehend the son of H D Revanna who himself is placed under judicial custody till May 14.

In a major twist to the entire case— the woman in the FIR alleged that Devaraje Gowda who apprised BJP of the sex videos involving Prajwal Revanna— has been harassing her for the past 10 months under the guise of helping her sell a property.

The woman also said that she came in contact with Gowda during the process involving the property that she wanted to sell. However, on the pretext of guiding her, the woman alleged that the whistleblower BJP leader physically assaulted and harassed her while Gowda also threatened the couple.

The woman has now sought police protection for herself and family. Further levelling allegations against Gowda in her plaint, she said that the politico had taken her to an isolated place where he assaulted her and threatened to kill the couple.

Former chief minister of Karnataka and Prajwal Revanna's uncle H D Kumaraswamy recently demanded a CBI probe in the Prajwal Revanna matter. However, Home Minister G Parameshwara turned down the demand for the investigation to be handed over to CBI.

US riot police have dismantled an anti-war and pro-Palestinian protest camp at the University of California at Los Angeles, a day after it was attacked by pro-Israel supporters.

At least 200 pro-Palestine protesters were arrested during the pre-dawn raid, led by a phalanx of California Highway Patrol officers carrying shields and batons, early on Thursday.

The protesters tried to block the officers' advance by their sheer numbers, shouting "push them back", while hundreds of pro-Palestinian activists who assembled outside the tent city were heard chanting "Shame on you" at the police.

According to estimates of local television station KABC-TV, 300 to 500 protesters were hunkered down inside the camp, while about 2,000 more had gathered outside the barricades in support.

The raid took place about a day after police watched on as pro-Israel groups violently attacked the encampment. Late Tuesday night, masked counter-demonstrators mounted a surprise assault on the camp, using sticks to beat the peaceful activists.

The assault went on for three hours into early Wednesday morning until police intervened and restored order.

The authorities’ slow response drew wide criticism from political leaders, including a spokesperson for California Governor Gavin Newsom who said "limited and delayed campus law enforcement response" to the unrest is "unacceptable."

The Pro-Palestine demonstrations began at Columbia University in New York City on April 17, and have spread across other campuses in the US in a student movement unlike any other this century.

US police arrested about 2,200 people during pro-Palestinian protests at college campuses across the country in recent weeks, the Associated Press reported.

A tally by the news agency recorded at least 56 incidents of arrests at 43 different US colleges or universities since April 18.

The students are calling for an end to Israel’s genocidal war on Gaza and demanding schools divest from companies that support the Israeli regime.

Israel launched the war on Gaza on October 7 after the Palestinian resistance movement Hamas waged the surprise Operation Al-Aqsa Storm against the occupying entity in response to the Israeli regime's decades-long campaign of bloodletting and devastation against Palestinians.

Tel Aviv has also blocked water, food, and electricity to Gaza, plunging the coastal strip into a humanitarian crisis.

Since the start of the offensive, the Israeli regime has killed at least 34,596 Palestinians and injured 77,816 others.

Bengaluru: In a fresh development in the alleged Hassan sex abuse case, JD(S) MLA H D Revanna, who was accused of sexually harassing his house help, has been booked for kidnapping a victim allegedly sexually assaulted by his son, Hassan MP Prajwal Revanna. The case was filed late Thursday evening at the KR Nagar police station in Mysuru.

The 20-year-old complainant from KR Nagara accused one Sathish Babanna of taking his mother away forcibly and keeping her in an unknown location at the behest of Revanna.

As per the FIR, Revanna has been named as accused 1 while Babanna was accused 2. The duo were booked under IPC Sections 364A (kidnapping for ransom), 365 (kidnapping or abducting with intent secretly and wrongfully to confine a person) and 34 (acts done by several persons in furtherance of common intention).

The complainant claimed that his mother, whose name and age were not revealed, had worked as a help in Revanna’s house and farm in Holenarasipura for six years, quit the job three years ago and returned to KR Nagara. She then worked for daily wages.

“Nearly three to four days before the Lok Sabha election, Sathish Babanna, who is known to us and hailed from our native place, took my mother to Holenarasipura after saying that Bhavani Revanna, the wife of MLA Revanna, had asked for her,” the complainant alleged, adding that Babanna dropped her back on the day of the polls.

Babanna allegedly told the victim’s mother and father to remain silent and evade the police if they came looking for them and to inform him of the developments.

On April 29, at around 9 pm, when the complainant was home, the suspect Babanna arrived, told the complainant’s mother that Revanna had asked for her and took her away on his motorcycle. The complainant claimed that he wasn’t aware of where Babanna took his mother and he had told him that if the police found her, a case would be registered and they would all go to jail.

On May 1, two of the complainant’s relatives called him on the phone and told him that there was a video of his mother being sexually assaulted by Prajwal and that it was a huge case, the FIR noted. He was also informed by his two friends of his "mother's videos being circulated".

When he asked Babanna later that night, he was allegedly told that there was a photo of his mother standing with a stick when Prajwal had quarrelled with someone earlier and an FIR had been registered. Babanna told the complainant that his mother would have to be released on bail, the FIR noted.

“Babanna told me not to speak on the matter on my phone and asked me to talk from a different phone,” he said, seeking action from the police.

The case has been transferred to the Special Investigation Team (SIT) set up to probe the Hassan sex scandal as per the government order.
