NASA on Saturday scrubbed the scheduled launch of its historic small car-size probe to “touch the Sun” from Cape Canaveral Air Force Station in Florida.
The agency is now targeting Sunday for the launch of the spacecraft which is designed to NASAgo all the way to the Sun’s atmosphere, or corona — closer to the Sun than any spacecraft in history.
“This morning’s launch of @NASASun’s #ParkerSolarProbe was scrubbed. Launch teams will attempt to launch on Sunday morning,” NASA said in a tweet on Saturday.
The probe is named after Eugene Parker, a solar physicist who in 1958 first predicted the existence of the solar wind, the stream of charged particles and magnetic fields that flow continuously from the Sun.
Nestled atop a United Launch Alliance Delta IV Heavy — one of the world’s most powerful rockets — with a third stage added, Parker Solar Probe will blast off toward the Sun with a whopping 55 times more energy than is required to reach Mars.
Weighing just 635 kgs, it is a relatively light spacecraft, Andy Driesman, project manager for the mission at the Johns Hopkins University Applied Physics Laboratory in the US, said in an earlier statement issued by NASA.
“And it needs to be, because it takes an immense amount of energy to get to our final orbit around the Sun,” Driesman added.
Zooming through space in a highly elliptical orbit, the Parker Solar Probe will reach speeds of up to 700,000 kms per hour, setting the record for the fastest spacecraft in history.
During its nominal mission lifetime of just under seven years, the Parker Solar Probe will complete 24 orbits of the Sun — reaching within 3.8 million miles of the Sun’s surface at the closest approach.
In an orbit this close to the Sun, the real challenge is to keep the spacecraft from burning up.

“Recent advances in materials science gave us the material to fashion a heat shield in front of the spacecraft not only to withstand the extreme heat of the Sun, but to remain cool on the backside,” said Adam Szabo, the mission scientist for the Parker Solar Probe at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The heat shield is made of a 4.5-inch thick carbon composite foam material between two carbon fibre face sheets.
At the Parker Solar Probe’s closest approach to the Sun, temperatures on the heat shield will reach nearly 1,371 degrees Celsius, but the spacecraft and its instruments will be kept at a relatively comfortable temperature of about 29.4 degrees Celsius. (IANS)
The new variant of the coronavirus Omicron is a variant of "concern" not "despair," Brazil's Health Minister Marcelo Queiroga said, adding that the country's health system is prepared for an eventual new Covid-19 wave.
"It is not a variant of despair because we have health authorities committed to providing quality care to our population," the Minister said.

A Brazilian citizen coming from South Africa was quarantined in the south American country after testing positive for Covid-19, since it was not known which variant had infected him, Xinhua news agency reported.
The first case of the Omicron variant was detected in South Africa and reported to the World Health Organization on November 24.

The new variant has a number of previously unseen mutations, mainly in the spike protein the virus uses to invade human cells.
Over the weekend, Queiroga asked Brazilians to remain calm, saying that measures against the new variant are the same, and the main weapon against Covid-19 is vaccination.
Brazil had accumulated 22,080,906 Covid-19 cases and 614,278 deaths from the virus as of Sunday.

Amit Rai Jain, a Baghpat-based businessman, has found 16 coins made of silver and copper which have a bull and a horseman engraved on them.
He found the coins from a mound, known locally as the 'Katha mound' in Khekhra, close to the Delhi-Saharanpur highway, on Sunday.

Jain told reporters that some of the coins are from the late 12th century AD, which is the era of Rajput king Prithviraj Chauhan.
"I keep frequenting the area, which is rich in archaeological finds. This time, it revealed something considered fascinating in Indian numismatics. The coins which I found belong to a series of Rajput rulers who remained dominant in the region comprising Rajasthan, Haryana, and the western Gangetic plains from the eighth century to 12th century AD," he said.
Jain, is a member of the Culture and History Association, an organisation comprising historians from western Uttar Pradesh.
K.K. Sharma, head of the department of history, Multanimal Modi College, Modinagar, confirmed the antiquity of the coins.

"This is an interesting find as the area remained with the Rajput kings for a couple of centuries. Horse and bull inscriptions on coins were quite common in those days. Horses used to be the primary vehicle of soldiers during battles and their depiction on coins is not a surprise. In fact, close to two dozen rulers between the seventh and 17th centuries used horses in some form or the other on their coins," he said.
Baghpat is well-known for the discovery of interesting historical artifacts, the most sensational being three chariots unearthed during the Archaeological Survey of India excavation held in Sinauli in June 2018, which marked the 'first-ever' physical evidence of Bronze Age chariots in India.
In 2006, Sinauli had revealed Harappan-era burial grounds where several discoveries were made such as that of painted grey ware pottery, skeletons, bronze swords, and copper vessels.

Featuring over 18 artists, the intention is to present a range and variety of sculptural expressions and encourage viewer participation and physical engagement with artworks once again, as the city opens up to mobility from the studios of Arunkumar HG, Ashiesh Shah, Gigi Scaria, G. R. Iranna, L. N. Tallur, Narayan Biswas, Mrinalini Mukherjee, Manjunath Kamath, Pooja Iranna, Himmat Shah, Jagannath Panda, Rajesh Ram, Riyas Komu, Sangam Vankhade, Sumedh R, Subodh Gupta, Sudarshan Shetty, Valay Shende, Vibha Galhotra and Vipul Kumar, the exhibition studies their involvement with the influences probing the limits and possibilities inherent in a sculpture's inescapable three-dimensional physicality.
One of the highlights of the show includes a selection of the rare hemp works by artist Mrinalini Mukherjee. Known for her distinctly contemporary style and use of dyed and woven hemp fibre, she worked with an unconventional material in the world of sculpting. Her four-decade-long career was an exemplar of a practice dedicated to formulating a language that was a mix of abstraction and figuration.
