U.S. rocket launched to bring NASA cargo to ISS

WASHINGTON: A U.S. rocket was launched on Wednesday from NASA’s Wallops Flight Facility on Virginia’s Eastern Shore, carrying cargo with the space agency’s resupply mission for the International Space Station (ISS).

The Antares rocket built by Northrop Grumman lifted off at 4:46 p.m. EDT, carrying the Cygnus cargo spacecraft to the ISS. The spacecraft successfully separated from the rocket about nine minutes after the blastoff, flying on its way to the space station, according to NASA’s live broadcast.

The spacecraft is expected to dock with the space station early Friday morning.

The spacecraft carried about 7,600 pounds (3,450 kg) of supplies and scientific experiments to the station. Some instruments it transports will examine astronauts’ health in microgravity.

A Canada-made instrument will perform on-orbit detection and quantification of cell surface molecules on a per cell and assess soluble molecule concentration in a liquid sample such as blood, saliva, or urine, thus sparing sample freezing and storing, according to NASA.

Another two new experiments will scrutinize aging-like changes in many astronauts on the space station, including changes to their arteries, and examine effects of spaceflight on the function of antibody production and immune memory.

A NASA-coordinated study published on April 11 showed that long-duration spaceflight may change astronauts’ gene expression and pose other health risks. NASA said it is necessary to take actions to prevent any damage to astronauts in a planned three-year space travel to Mars in 2030s.

Also on this mission, the spacecraft demonstrated for the first time its ability to load cargo 24 hours before a scheduled launch. Previously, cargo had to be put in place about four days prior to the liftoff, making some experiments challenging.

The spacecraft will remain attached to the space station for approximately two months before departing with up to 7,700 pounds (about 3,500 kg) of cargo for disposal, according to Northrop Grumman.

Fight vaccine hesitancy as ‘contagious disease’

Published

on

GENEVA: Faced with a global resurgence of measles, health experts called today for countries to step up the fight against vaccine resistance, warning the movement was spreading like a contagious disease.
World Health Organization chief Tedros Adhanom Ghebreyesus joined experts and health ministers from a range of countries at an event on “promoting vaccine confidence”, amid rising concerns that resistance to immunization is allowing preventable diseases to flourish.
“No country can afford to be complacent about immunization,” Tedros told the meeting in Geneva, where the WHO is hosting its main annual gathering.
The WHO says cases of measles — a highly contagious viral infection that can prove fatal — surged 300 percent in 2018.
The resurgence of the once all-but-eradicated disease is linked to the growing anti-vaccine movement in richer nations, which has been identified as a major global health threat.
“It’s a contagious disease,” Seth Berkley, who heads the GAVI Vaccine Alliance, told AFP, warning that misinformation about vaccine safety “spreads at the speed of light.”
The anti-vax phenomenon has adherents across Western countries but especially in the US, where it has been fuelled by the spread on social media of medically baseless claims, debunked 20 years ago, that the jab could cause autism.
The United States, which sponsored Tuesday’s event with the EU and Brazil, lamented the “misinformation” causing vaccination rates in the country to decline.
“Vaccines are some of the most thoroughly tested medical products we have. Vaccines are safe, effective, and lifesaving,” US Health and Human Services Secretary Alex Azar told the meeting.
He slammed “social media conspiracy groups (that) confuse well-meaning parents so they hesitate to get the recommended vaccinations.”This misinformation has real impacts,” he said, pointing to the more than 700 measles cases in the US so far this year.
Azar dismissed questions about whether past statements by President Donald Trump in support of some anti-vaccination movement claims may bear some responsibility for the problem.
Pointing to recent comments by the president urging Americans to “get your kids vaccinated”, he stressed Trump was “extremely firm” in his support of vaccination.
EU Health Commissioner Vytenis Andriukatis meanwhile suggested that vaccine skepticism was in part linked to the fact that vaccines have been so effective that most people have no concept of how devastating the diseases they prevent can be.
“We have become victims of our own success,” he said.
Among the measures being taken to inoculate populations against the spread of misinformation about vaccine safety was putting pressure on social media companies like Facebook and Twitter to remove or flag demonstrably false information.
“This is wrong information that is killing people,” Berkley said.
According to WHO, vaccines save some three million lives annually.
“Vaccines do not cause autism. Vaccines actually cause adults,” said Katherine O’Brien, who heads WHO’s immunization department.

Eiffel Tower climber ‘admitted to psychiatric unit’

Published

on

PARIS: A man, believed to be Russian, who sparked a mass evacuation of the Eiffel Tower by scaling the iconic Paris landmark, has been admitted to a psychiatric unit, legal sources said today.
The man caused chaos Monday and the closure of the monument to tourists by spending six hours clinging to the outer metal framework of the Eiffel Tower. His identity has not been disclosed. He was questioned by police on Tuesday and had now been admitted to the psychiatric hospital of the police, legal sources told the Media. An investigation had been opened for unauthorized entry into a cultural monument, a judicial source said.
“It is a Russian man, who has suicidal tendencies,” said a source close to the case, asking not to be named. Firemen, who had rappelled down from the tower’s third-floor observation deck to near the black-clad climber, managed to persuade him to come down. Some 2,500 people, who had come to visit the Eiffel Tower, had to be evacuated Monday but it reopened as normal on Tuesday.
