International Space Station Maneuver to Avoid Satellite Junk

The International Space Station will conduct a brief maneuver on Wednesday to dodge a fragment of an inactive Chinese satellite, the Russian space agency Roscosmos said.

Roscosmos said the station crewed by seven astronauts will climb 1,240 meters high and settle into orbit 470.7 km (292 mi) above Earth to avoid a close encounter with the fragment. It did not say how big the debris was.

“To dodge ‘space junk,’ (Mission Control) experts have calculated how to recover the orbit of the International Space Station,” the agency statement said.

The station will rely on the engines of the Progress Space Truck that is docked to carry out the move.

Satellites hovering around Earth are threatened by an ever-increasing amount of space debris, with insurers offering coverage to equipment that transmits texts, maps, video and scientific data.

The document reaffirms goals in Paris in 2015 to limit warming to “well below” 2 °C (3.6 °F) since pre-industrial times, with an effort to keep 1.5 °C (2.7 °F) warmer. There are more stringent goals to achieve. ) was preferred because it would “significantly keep” the damage from climate change.

Highlighting the challenge of meeting those goals, the document expresses “alarm and concern that human activities have caused approximately 1.1 C (2 F) of global warming to date and that this effect is already in every region.” being felt.”

Small island nations, which are particularly vulnerable to warming, worry that little is being done to stop warming at the 1.5-degree target – and that allowing temperatures to rise by 2 degrees is catastrophic for their countries. Will happen.

“For the Pacific (small island states), climate change is the single biggest, single biggest threat to our livelihoods, security and well-being. We don’t need much scientific evidence or targets without a plan to reach them or shop ,” the Marshall Islands Minister of Health and Human Services told fellow negotiators on Wednesday. “The limit of 1.5 is not negotiable.”

Separate draft resolutions were also issued for debate in negotiations on other issues, including rules for international carbon markets and the frequency by which countries are to report on their efforts.

The draft calls on nations that do not have national targets that will fit with a 1.5- or 2-degree range to come back with stronger goals next year. Depending on how the language is interpreted, the provision may apply to most countries. Analysts at the World Resources Institute count that element as a victory for weaker countries.

“This is important language,” David Vasco, director of the WRI International Climate Initiative, said on Wednesday. “Countries are really expected and on the hook to do something in that time frame to adjust.”

Greenpeace’s Morgan said it would have been even better to set the need for new goals each year.

For one of the bigger issues for poor countries, the draft vaguely “urges” developed countries to compensate developing countries for “loss and damage”, a phrase that some rich countries do not like. But there is no concrete financial commitment.

“It’s often the most difficult moment,” Achim Steiner, head of the United Nations Development Program and former head of the United Nations Office for the Environment, said of the state of the two-week talks.

“The first week is over, you suddenly recognize that there are many fundamentally different issues that simply cannot be resolved. The clock is ticking,” he told the Associated Press.
