Russian anti-satellite missile test endangers space station crew – NASA

By Idrees Ali and Steve Gorman

WASHINGTON (Reuters) -An anti-satellite missile test Russia conducted on Monday generated a debris field in low-Earth orbit that endangered the International Space Station and will pose a hazard to space activities for years, U.S. officials said.

The seven-member space station crew – four U.S. astronauts, a German astronaut and two Russian cosmonauts – were directed to take shelter in their docked spaceship capsules for two hours after the test as a precaution to allow for a quick getaway had it been necessary, NASA said.

The research lab, orbiting about 250 miles (402 km) above Earth, continued to pass through or near the debris cluster every 90 minutes, but NASA specialists determined it was safe for the crew to return to the station’s interior after the third pass, the agency said.

The crew was also ordered to seal off hatches to several modules of the International Space Station (ISS) for the time being, according to NASA.

“NASA will continue monitoring the debris in the coming days and beyond to ensure the safety of our crew in orbit,” NASA chief Bill Nelson said in the statement.

Experts say the testing of weapons that shatter satellites in orbit pose a space hazard by creating clouds of fragments that can collide with other objects, setting off a chain reaction of projectiles through Earth orbit.

THOUSANDS OF FRAGMENTS

The Russian military and ministry of defense were not immediately available for comment. A message posted on Twitter by the Russian space agency Roscosmos downplayed the danger.

“The orbit of the object, which forced the crew today to move into spacecraft according to standard procedures, has moved away from the ISS orbit,” Roscosmos tweeted. “The station is in the green zone.”

The direct-ascent anti-satellite missile fired by Russia into one of its own satellites generated more than 1,500 pieces of “trackable orbital debris” and would likely spawn hundreds of thousands of smaller fragments, the U.S. Space Command said in a statement.

“Russia has demonstrated a deliberate disregard for the security, safety, stability and long-term sustainability of the space domain for all nations,” space command chief U.S. Army General James Dickinson said.

The debris from the missile test “will continue to pose a threat to activities in outer space for years to come, putting satellites and space missions at risk, as well as forcing more collision avoidance maneuvers,” he said.

U.S. Secretary of State Antony Blinken condemned the missile test as “reckless and irresponsible.” At the Pentagon, spokesman John Kirby said the test showed the need to firmly establish norms of behavior in space.

“It is unthinkable that Russia would endanger not only the American and international partner astronauts on the ISS, but also their own cosmonauts,” Nelson said. He said the cloud of debris also posed a threat to a separate Chinese space station under construction and the three-member crew of “taikonauts” aboard that outpost.

The incident came just four days after the latest group of four space station astronauts – Americans Raja Chair, Tom Marshburn and Kayla Barron of NASA and European Space Agency crewmate Matthias Maurer of Germany – arrived at the orbiting platform to begin a six-month science mission.

They were welcomed by three space station crew members already on board – U.S. astronaut Mark Vande Hei and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov.

“Thanks for the crazy but well-coordinated day. We really appreciated all the situational awareness you gave us,” Vande Hei said in a Monday radio transmission to NASA posted online by Space.com. “It was certainly a great way to bond as a crew, starting off our very first workday in space.”

The space station, spanning the size of an American football field end to end, has been continuously occupied since November 2000, operated by an international partnership of five space agencies from 15 countries, including Russia’s Roscosmos.

Russia is not the first country to conduct anti-satellite tests in space. The United States performed the first in 1959, when satellites were rare and new.

In April Russia carried out another test of an anti-satellite missile as officials have said that space will increasingly become an important domain for warfare.

In 2019, India shot down one of its own satellites in low-Earth orbit with a ground-to-space missile.

These tests have raised questions about the long-term sustainability of space operations essential to a huge range of commercial activities, from telecommunications and weather forecasting to banking and GPS services.

Australians shelter from bushfires as political heat climbs

By Colin Packham

SYDNEY (Reuters) – Firefighters battled hundreds of bushfires across Australia on Thursday as scores of blazes sprang up in new locations, triggering warnings that it was too late for some residents to evacuate.

As Thick smoke blanketed the most populous city of Sydney for a third day, residents were urged to keep children indoors, stepping up pressure on Prime Minister Scott Morrison to tackle climate change.

By early afternoon, dozens of fires were burning across the southeastern state of Victoria and temperatures of 40.9 Celsius (105.6 F) in Melbourne, its capital, matched the hottest day on record in 1894, Australia’s weather bureau said.

Authorities warned residents of towns about 50 km (31 miles) north of Ballarat, the state’s third largest city, that it was too late for them to evacuate safely.

“You are in danger, act now to protect yourself,” fire authorities said in an alert. “It is too late to leave. The safest option is to take shelter indoors immediately.”

Blazes across several states have endangered thousands of people, killing at least four people this month, burning about 2.5 million acres (1 million hectares) of farmland and bush and destroying more than 400 homes.

The early arrival and severity of the fires in the southern hemisphere spring follows three years of drought that experts have linked to climate change and which have left bushland tinder-dry.

With 10 days remaining to the official start of summer, extreme temperatures and high winds have sparked wildfires in new areas, even as firefighters tracked the crisis across the mainland, the Northern Territory and the island of Tasmania.

In Victoria, power to more than 100,000 homes was knocked out amid lightning strikes and strong, gusty winds of more than 110 kph (68 mph) that knocked tree branches into power lines, ahead of a cool change expected to bring relief in the evening.

The extensive damage was likely to leave some customers without power through the night as utilities worked to restore networks and fix downed powerlines, a spokeswoman for power provider Ausnet said.

State authorities issued its first Code Red alert in a decade, signifying the worst possible bushfire conditions, warning that should a fire start it would be fast moving, unpredictable and probably uncontrollable.

In the state of New South Wales, strong winds blew smoke from 60 fires still burning over much of Sydney, shrouding the harbor city and its famous landmarks in thick smog.

The state imposed tough new water curbs in Sydney from Dec. 10, when a key dam is expected to be down to 45% capacity. Residents face fines if they use hoses to water their gardens and wash their cars.

CLIMATE POLITICS

The unrelenting conditions have sharpened attention on the climate change policies of Prime Minister Scott Morrison, who rejected any link.

“Climate change is a global phenomenon, and we’re doing our bit as part of the response to climate change,” Morrison told ABC radio.

“To suggest that, with just 1.3% of global emissions, that Australia doing something differently – more or less – would have changed the fire outcome this season, I don’t think that stands up to any credible scientific evidence at all.”

Morrison’s conservative government has committed to the Paris Agreement for a cut in emissions from 26% to 28% by 2030, versus 2005 levels. Critics say current projections suggest it will miss that target and have urged remedial steps.
