World's first mission to touch the Sun lifts off

Washington, Aug 12: NASA's Parker Solar Probe, mankind's first mission to 'touch' the Sun, has been launched on Sunday on a seven-year-long journey to unlock the mysteries of our star's fiery outer atmosphere and its effects on space weather.

Liftoff took place from Space Launch Complex 37 at Cape Canaveral Air Force Station in the US early on Sunday.

The launch of the United Launch Alliance Delta IV Heavy rocket carrying the spacecraft was scrubbed yesterday due to a violation of a launch limit, resulting in a hold.

The car-sized spacecraft will travel directly into the Sun's atmosphere, about four million miles from its surface - and more than seven times closer than any spacecraft has come before, thanks to its innovative Thermal Protection System.

The USD 1.5 billion mission will perform the closest-ever observations of a star when it travels through the Sun's outer atmosphere, called the corona.

It will make 24 passes through the corona during its seven-year mission. The mission will rely on measurements and imaging to revolutionise our understanding of the corona and how processes there ultimately affect near-Earth space.

The Parker Solar Probe carries a lineup of instruments to study the Sun both remotely and in situ, or directly. Together, the data from these instruments should help scientists answer three foundational questions about our star.

A Sun-skimming mission like Parker Solar Probe has been a dream of scientists for decades, but only recently has the required technology - like the heat shield, solar array cooling system, and fault management system - been available to make such a mission a reality.

Parker Solar Probe will explore the corona, a region of the Sun only seen from Earth when the Moon blocks out the Sun's bright face during total solar eclipses.

The corona holds the answers to many of scientists' outstanding questions about the Sun's activity and processes.

Ottawa, Mar 16: An Indian-origin couple and their teenage daughter were killed in a "suspicious" fire which tore through their home last week in Canada's Ontario province, police said on Friday.

A fire engulfed a home at the Big Sky Way and Van Kirk Drive area of Brampton on March 7, a press release by the Peel Police said.

After the blaze was put out, investigators located what was believed to be human remains within the gutted house, but the number of people killed couldn't be ascertained at the time.

The charred remains were on Friday identified as those of three family members: 51-year-old Rajiv Warikoo; his wife, 47-year-old Shilpa Kotha; and their 16-year-old daughter, Mahek Warikoo.

Police said that they resided at the address before the fire.

Peel police Constable Taryn Young on Friday said the fire had been deemed suspicious, the CTV news channel reported.

"At this time, we are investigating this with our homicide bureau, and we are deeming this as suspicious as the Ontario Fire Marshal has deemed that this fire was not accidental," the report quoted Young as saying.

"There's not much left to it," Young said when asked about the possible cause of the fire.

"Looking into something like that as a fire marshal, I'm sure it's very tough when there is not much left to look at. But we are exhausting all avenues," she said.

The deceased family's neighbour, Kenneth Yousaf, said that the family had lived on the street for about 15 years, and he never noticed any problems with them.

Yousaf said he was alerted to the fire last week by a family member, who heard a big "bang." "When we came out, the house was on fire. So sad. Within a few hours, everything was down to the ground," the report quoted Yousaf as saying.

In a press release, police said they are continuing to investigate the deaths of the three family members and urged anyone with information to come forward.

"The circumstances surrounding the house fire remains the focus of an active investigation, and anyone with information or video footage (dashcam or otherwise) is urged to contact Homicide detectives," police said.

The Enforcement Directorate on Friday produced Delhi Chief Minister Arvind Kejriwal before the Rouse Avenue court and sought a 10-day custody in the excise policy-linked money laundering case. "Kejriwal was the kingpin of the scam," the ED reportedly told the court after the AAP chief was produced before Special Judge Kaveri Baweja around 2 pm amid tight security. 

ASG S V Raju was appearing for the agency, while Senior Advocate Abhishek Manu Singhvi is representing Kejriwal. 

Raju in his argument said Kejriwal was "directly involved in formulation of the (liquor) policy... he was involved in handling of proceeds of crime as well in the Goa election campaign."

"The expert committee was constituted but it was a sham committee. The policy was made in such a manner that it would enable the taking of bribes and recoupment of people who gave the bribes," the ED counsel said. 

Kejriwal was produced in the trial court shortly after he withdrew from the Supreme Court his plea against arrest by the Enforcement Directorate in the excise policy-linked money laundering case. Kejriwal's counsel said he would contest the remand proceedings before the trial court and then come back to the apex court with another petition.

Bengaluru: Prime Minister Narendra Modi would formally kickstart the BJP's Lok Sabha election campaign in Karnataka on Saturday from Congress President Mallikarjun Kharge's home turf— Kalaburagi.

He is scheduled to address a mega public meeting at the district headquarters town's N V Ground at 2 pm.

Kharge, who had represented Kalaburagi (Gulbarga Lok Sabha segment) twice in the past, lost to BJP's Umesh Jadhav by a margin of 95,452 votes in the 2019 general elections here— the octogenarian leader's first electoral loss in his political life spanning several decades.

BJP has once again fielded Jadhav from the segment.

Speculations are rife that the Leader of Opposition in Rajya Sabha, who has the role of managing the party nationally and coordinating with the opposition I.N.D.I.A bloc, may not contest the coming polls and, instead, the Congress is likely to field his son-in-law Radhakrishna Doddamani, a businessman, who also manages educational institutions.

On March 18, Modi will be in Shivamogga, the home district of veteran BJP leader B S Yediyurappa, and is scheduled to address a huge public meeting at 2 pm.

Yediyurappa's son B Y Raghavendra is the sitting MP from Shivamogga and has been re-nominated by the party. Yediyurappa's other son B Y Vijayendra, who represents Shikaripura assembly constituency in the district, is the state BJP President.

BJP has announced candidates for 20 seats in the State, which has a total of 28 constituencies.

After being ousted from power by the Congress in the 2023 Assembly polls, the BJP now is making a strong bid to regain the lost ground in Karnataka.

The BJP won 25 out of total 28 seats in the previous elections, and had ensured the win of a party supported independent candidate in Mandya. The then ruling Congress-JD(S) alliance had come a cropper winning just one seat each.

It is a role reversal of sorts for JD(S), which joined the NDA last September and has forged an electoral alliance with the BJP. The regional party is expected to contest in three seats— Mandya, Hassan and Kolar.

Sharing details of Modi's visit, state BJP General Secretary Sunil Kumar on Wednesday said BJP National President J P Nadda, Union Home Minister Amit Shah, Chief Minister of Uttar Pradesh Yogi Adityanath along with other leaders will visit different Lok Sabha constituencies for campaigning in the coming days.

Speaking about the party's poll preparations, he said: "We have divided 28 Lok Sabha constituencies into eight clusters for Lok Sabha elections. Keeping in view the local political and geographical background, programmes and strategies are being worked out in those eight clusters."

Several senior leaders including Shah and Nadda have already visited one of these clusters, Kumar said, adding, "Workers' convention, well-wishers' contacts have been made and election preparations are on in all these eight clusters. In the second phase, large public meetings will be held."
