NASA confirms Curiosity rovers surprising Mars methane discovery

first_img 17 Photos Share your voice A 23rd-century tourist guide to the galaxy Curiosity rover’s discovery is still exciting — it just doesn’t help us confirm life on Mars. Seán Doran/Laura Martínez/CNET Curiosity, NASA’s Mars rover, has had a busy weekend. After detecting the highest levels of methane yet seen on Mars last weekend, NASA put a pause on the rover’s other science activities to follow up on the discovery. On Monday, data from Curiosity’s subsequent experiment filtered back to NASA and the spike in methane levels had disappeared, dropping to background levels.”A plume came and a plume went,” said Paul Mahaffy, principal investigator overseeing Curiosity’s Sample Analysis at Mars (SAM) instrument, during a NASA town hall event at the Astrobiology Science Conference on Monday. “We’re very confident of the measurement.”As the news of Curiosity’s startling finding broke over the weekend, many suggested the high methane could hint at the possibility of life on Mars. Methane is an important molecule on Earth and many living organisms excrete it, including microbes.Mahaffy explained that Curiosity had detected an unusually high level of methane last Wednesday during a routine experiment which tests the concentration of molecules in the atmosphere. The data came back on Thursday and showed a methane level of 21 parts per billion — around three times higher than had ever been seen before. Thus, Curiosity’s weekend plans were scrapped to run the experiment again.”The methane plume went away … it’s back down now to below 1 part per billion,” Mahaffy said, noting the measurement is consistent with what has previously been seen on Mars. NASA cautioned as the news broke over the weekend that the methane detection appears to be from a “transient plume” and Curiosity is not outfitted with the appropriate instruments to tell us whether the plume is biological or geological in origin.What does that mean for life on Mars? Well, not a lot. Although the original finding was confirmed, we’re no closer to discovering its source right now — that will be up to some of the spacecraft orbiting the Red Planet and future Mars missions. Moreover, the methane spike is certainly an unusual phenomenon but it has been seen by scientists before.”The methane mystery continues,” said Ashwin Vasavada, Curiosity’s project scientist at NASA, in a statement. “We’re more motivated than ever to keep measuring and put our brains together to figure out how methane behaves in the Martian atmosphere.”   Comment 1 Sci-Tech Tags NASAlast_img read more

Arrest warrant issued against Shashi Tharoor over controversial Hindu Pakistan jibe

first_img[Representational Image] IANSAn arrest warrant was issued against Congress MP Shashi Tharoor on Tuesday by a Kolkata court over a remark made by him in 2018 on ‘Hindu Pakistan’.A Kolkata Metropolitan Magistrate issued the arrest warrant against Tharoor after Sumeet Chowdhary, a lawyer, filed a case against him under Section 153A/295A of the Indian Penal Code (IPC) and Section 2 of the Prevention of Insults to National Honour Act, 1971, claiming that his controversial comments had hurt the religious sentiments of people and was an insult to India.The Congress MP from Kerala’s capital Thiruvananthapuram had claimed that India would become like Pakistan for Hindus if the Bharatiya Janata Party (BJP) won the 2019 Lok Sabha elections.In July 2018, Tharoor, while addressing an event at Thiruvananthapuram, said that if the BJP won the 2019 LS elections, it will destroy the Indian Constitution and create a new one that will be based on Hindu Rashtra principles, where the rights of minorities will not be respected and it will lead to the creation of a “Hindu Pakistan”.”The new one will be the one which will enshrine principles of Hindu Rashtra, that will remove equality for minorities, that will create a Hindu Pakistan and that isn’t what Mahatama Gandhi, Nehru, Sardar Patel, Maulana Azad and great heroes of freedom struggle fought for,” he had said during the event.”The BJP already has more than 20 states under their belt, so a Rajya Sabha majority looks near… Now if they could muster what they managed during the last Lok Sabha polls, India is done for,” he had added.However, Tharoor did not apologise for his comments even after BJP lashed out against him for the controversial remark. He defended his comment on social media claiming that the BJP and the Rashtriya Swayamsevak Sangh (RSS) idea of a ‘Hindu Rashtra’ was the mirror image of Pakistan. “We want to preserve India and not turn our beloved country into a Hindu version of Pakistan,” he wrote on Facebook on 12 July 2018. The Court had issued a summons to him last year but he did not appear for the hearing, following which the court has issued a warrant against him.last_img read more
