Giant Fossilised Footprint Of Dinosaur Found in China
(CTN News) – A team of palaeontologists believes they have discovered fossilized footprints of one of China’s largest raptors. The collection of five fossilized dinosaur footprints is half the length of a school bus.
The footprints were discovered in a dinosaur trackway in south-east China in 2020. Scientists believe dinosaurs walked over the muddy river during the Cretaceous period, leaving footprints. Some footprints have been preserved for tens of millions of years.
The dinosaur trackway was unearthed in Longxiang and is around the size of a hockey rink. Some of the footprints are unusually formed, with intact imprints of only two toes.

Raptors, or predatory birds, are often small and referred to as deinonychosaurs. For example, a Velociraptor is around the size of a turkey. Few raptors, such as the Utahraptor and Dakotaraptor, increased in size significantly, reaching lengths of 5 to 6 metres. The Triassic ichthyosaur was the largest raptor known until now.

According to the scientists, the predator would have attacked its prey with a pair of huge “killing claws” on each foot.
What scientists discovered recently in China is massive, far larger than the largest superpredator known to date.
Scott Persons of the College of Charleston in South Carolina, and his colleagues, added another large raptor to the list. They named it Fujianipus, and they believe it lived in East Asia some 96 million years ago.

Persons and his colleagues are currently working on areas of Fujianipus’ skeleton, therefore little is known. The investigators only discovered a few of its 36-centimetre-long imprints.
“Preservation conditions were right for footprints but not so great for bones,” Persons said. However, scientists are certain that the footprints belong to a raptor because each one contains the imprint of only two toes, which corresponds to the foot anatomy of raptors. Raptors generally have three toes, but they keep one off the ground to preserve the big claw at the tip from wear and tear.
People believe Fujianipus demonstrates that raptors had the ability to grow much larger and compete with the largest predatory dinosaurs on the landscape at the time – allosauroids, some of which exceeded 10 metres or more in length.
According to Persons, raptors had an advantage over allosauroids in terms of speed. However, without fossilized leg bones, the researchers cannot correctly measure Fujianipus’ speed.
NEW YORK — To save power, NASA turned off another scientific equipment on its long-running Voyager 2 spacecraft.
NASA Switches Off Instrument On the Spacecraft To Save Power
The space agency announced on Tuesday that 2’s plasma science instrument, meant to study the movement of charged atoms, was turned off in late September to allow the spacecraft to continue exploring for as long as possible, which is estimated to be into the 2030s.
NASA turned off a suite of instruments on Voyager 2 and its twin, Voyager 1, after exploring the gas giant planets in the 1980s. Both are currently in interstellar space or the region between stars. The plasma instrument on Voyager 1 stopped working years ago and was finally shut off in 2007.
The remaining four instruments on 2 will continue to collect data on magnetic fields and particles. Its mission is to investigate the regions of space beyond the sun’s protective sphere.

It launched in 1977, is the only spacecraft to have visited Uranus and Neptune. It is now more than 12 billion miles (19.31 billion kilometers) from Earth. 1 is more than 15 billion miles (24.14 billion kilometers) beyond Earth.

MIAMI — Hurricane Kirk’s waves could generate life-threatening surf and rip current conditions this weekend throughout the United States East Coast, as well as in Bermuda, the Greater Antilles, and the Bahamas, according to forecasters.
Kirk was a Category 3 hurricane in the middle Atlantic Ocean that might grow further but was predicted to stay away from land, according to the Miami-based National Hurricane Center on Thursday.
Hurricane Kirk Could Cause Dangerous Surf Conditions Along The US East Coast
Kirk-generated swells were forecast to reach parts of the Leeward Islands on Friday, Bermuda and the Greater Antilles on Saturday, and the East Coast and the Bahamas on Sunday, according to the center.
No coastal watches or warnings were in effect. The major storm was around 1,130 miles (1,820 kilometers) east of the Leeward Islands, with maximum sustained winds of 125 mph (205 km/h).
Meanwhile, Tropical Storm Leslie formed late Wednesday in the eastern Atlantic and is expected to strengthen into a hurricane in the following days, forecasters said. It was also not considered a threat to the land.

The storm was about 540 miles (870 kilometers) southwest of Cabo Verde’s southernmost tip, with maximum sustained winds of 45 mph (75 kph), according to the center.
The storms raged in the Atlantic as rescuers in the United States Southeast sought for missing persons after Hurricane Helene struck last week, leaving a trail of death and devastation.

NASA has announced astronauts Butch Wilmore and Suni Williams are safely in orbit on the first crewed flight test of Boeing’s Starliner spacecraft heading for the International Space Station.
As part of NASA’s Boeing Crew Flight Test, the astronauts launched a ULA (United Launch Alliance) Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida at 10:52 a.m. EDT Wednesday for an end-to-end test of the Starliner system.
“Two brave NASA astronauts are well on their way to this historic first test flight of a brand-new spacecraft,” stated NASA Administrator Bill Nelson. “Boeing’s Starliner represents a new era of American exploration. Human spaceflight is a risky endeavor, but it is worth it. It is an exciting time for NASA, our commercial partners, and the future of space exploration. “Go Starliner, Butch, and Suni!”
The flight test is part of NASA’s Commercial Crew Program and will help validate the transportation system, launch pad, rocket, spacecraft, in-orbit operations capabilities, and return to Earth with astronauts aboard as the agency prepares to certify Starliner for rotational missions to the space station. Starliner has already completed two uncrewed orbital missions, including a test to and from the space station, as well as a pad abort demonstration.
Boeing Starliner Makes Orbit
“With Starliner’s launch, separation from the rocket, and arrival in orbit, Boeing’s Crew Flight Test is right on track,” said Mark Nappi, vice president and program manager for Boeing’s Commercial Crew Program. “Everyone is focused on giving Suni and Butch a safe, comfortable, ride and performing a successful test mission from start to finish.”
Boeing’s mission control center in Houston will supervise a sequence of autonomous spacecraft maneuvers while Starliner is in flight. NASA teams will supervise space station activities from the Mission Control Center at the agency’s Johnson Space Center in Houston.
“Flying crew on Starliner represents over a decade of work by the Commercial Crew Program and our partners at Boeing and ULA,” said Steve Stich, Commercial Crew Program Manager at NASA’s Johnson Space Center in Houston. “For many of us, this is a career-defining occasion, ushering in a new crew transportation capacity for our agency and our country. We will take it one step at a time, putting Starliner through its paces and remaining watchful until Butch and Suni safely land back on Earth at the end of this test journey.”
At about 12:15 p.m., Starliner will dock autonomously to the forward-facing port of the station’s Harmony module. Thursday, June 6, and will remain at the orbital laboratory for almost a week.
Wilmore and Williams will help ensure that the spacecraft is functioning properly by testing the environmental control system, the displays and control system, and moving the thrusters, among other things, during flight.
Wilmore and Williams will join the Expedition 71 crew, which includes NASA astronauts Michael Barratt, Matt Dominick, Tracy C. Dyson, and Jeanette Epps, as well as Roscosmos cosmonauts Nikolai Chub, Alexander Grebenkin, and Oleg Kononenko.
