ERS-2 satellite in orbit for 30 years crashes into Pacific between Alaska and Hawaii

A European satellite that has been in orbit for nearly three decades crashed into the North Pacific Ocean, between Alaska and Hawaii, on Wednesday.

The European Space Agency (ESA) said that the defunct satellite European Remote Sensing 2 (ERS-2) re-entered the atmosphere and that "no damage to property was reported".

ERS-2 was an Earth observation satellite, launched in 1995, and provided insights into the planet, including the chemistry of the atmosphere, behaviour of the oceans and the effects of human activity on the environment.

“Having far exceeded its planned lifetime of three years, ESA took the decision to deorbit ERS-2 in 2011 in light of growing concern over the long-term hazard that orbital debris poses to current and future space activities," the agency said in a statement.

Photos of the satellite's journey home were taken by Australian company HEO using its own satellites over the past month.

While modern missions by ESA are designed to ensure that satellites are disposed of more responsibly, older missions were not created that way.

“ESA’s space debris mitigation policy has been updated multiple times since 2008, as recently as November 2023,” the agency said.

“Our missions in Earth orbit are now increasingly designed to conduct controlled re-entries at the end of their life that allow operators to accurately target over which region on Earth they re-enter.

“However, ESA continues to make efforts to dispose of its older satellites (such as ERS-2, Aeolus, Cluster and Integral) in more sustainable ways than were originally planned.”

Over the years, there have been several large defunct rocket body parts that have made uncontrolled re-entries into Earth.

Some of these include China's rocket boosters that have tumbled back into the oceans, as well as debris from SpaceX's Dragon capsule that was found in an Australian farmland in August, 2022.

What is hepatitis?

Hepatitis is an inflammation of the liver, which can lead to fibrosis (scarring), cirrhosis or liver cancer.

There are 5 main hepatitis viruses, referred to as types A, B, C, D and E.

Hepatitis C is mostly transmitted through exposure to infective blood. This can occur through blood transfusions, contaminated injections during medical procedures, and through injecting drugs. Sexual transmission is also possible, but is much less common.

People infected with hepatitis C experience few or no symptoms, meaning they can live with the virus for years without being diagnosed. This delay in treatment can increase the risk of significant liver damage.

There are an estimated 170 million carriers of Hepatitis C around the world.

The virus causes approximately 399,000 fatalities each year worldwide, according to WHO.

Day 1, Abu Dhabi Test: At a glance

Moment of the day Dimuth Karunaratne had batted with plenty of pluck, and no little skill, in getting to within seven runs of a first-day century. Then, while he ran what he thought was a comfortable single to mid-on, his batting partner Dinesh Chandimal opted to stay at home. The opener was run out by the length of the pitch.

Stat of the day - 1 One six was hit on Day 1. The boundary was only breached 18 times in total over the course of the 90 overs. When it did arrive, the lone six was a thing of beauty, as Niroshan Dickwella effortlessly clipped Mohammed Amir over the square-leg boundary.

The verdict Three wickets down at lunch, on a featherbed wicket having won the toss, and Sri Lanka’s fragile confidence must have been waning. Then Karunaratne and Chandimal's alliance of precisely 100 gave them a foothold in the match. Dickwella’s free-spirited strokeplay meant the Sri Lankans were handily placed at 227 for four at the close.
