SpaceX launches four astronauts to International Space Station******

SpaceX Falcon 9 rocket with the Crew Dragon spacecraft lifts off with four astronauts on board from launch pad 39A at the Kennedy Space Center on November 10, 2021, in Cape Canaveral, Florida.。

After a series of delays, Elon Musk's private company SpaceX launched four astronauts to the International Space Station on Wednesday night on the "Crew-3" mission.。

The orbital outpost is currently operating with just one NASA astronaut in the US segment to welcome the incoming crew, after the astronauts of the earlier Crew-2 mission splashed down in the Gulf of Mexico on Sunday night.。

Crew-3's Raja Chari, Kayla Barron and Tom Marshburn of the United States and Matthias Maurer of Germany blasted off aboard a Crew Dragon capsule fixed to a Falcon 9 rocket at 9:03pm local time (2:03am GMT on Thursday) from the Kennedy Space Center in Florida. The launch was greeted by applause in the SpaceX control room.。

The spaceship, called Endurance, will dock with the ISS at 7:10pm on Thursday (0:10am GMT on Friday).。

NASA associate administrator and former astronaut Bob Cabana described the launch as "fantastic."

"I think it's an amazing time for America's space program. We are definitely at an inflection point," he added.。

The flight was initially postponed from October 31 first for weather, then a "minor medical issue" affecting one of the crew. NASA did not say who it was but said it was not COVID-19 related.。

'American ingenuity'

Chari, a US Air Force colonel, is commanding the mission and making his first trip to space, along with Barron and Maurer.。

Marshburn, a medical doctor, flew aboard a Space Shuttle in 2009 and a Russian Soyuz spacecraft in a mission from 2012-13.。

Barron, who along with Chari was selected for the NASA astronaut corps in 2017, the most recent recruitment, previously served as a submarine warfare officer for the Navy, while Maurer, a materials science engineer, will become the 12th German in the cosmos.。

Crew-3 is part of NASA's multibillion-dollar partnership with SpaceX that it signed after ending the Space Shuttle program in 2011 and aims to restore US capacity to carry out human spaceflight.。

NASA chief Bill Nelson said on Twitter he had attended the launch.。

"We're seeing the power of American ingenuity right before our eyes," he wrote after the rocket took off, hailing the NASA-SpaceX partnership.。

"Godspeed, Crew-3 – I can't wait to see all that you accomplish!"

The quartet will spend six months on the orbital outpost and conduct research to help inform future deep space exploration and benefit life on Earth.。

Scientific highlights of the mission include an experiment to grow plants in space without soil or other growth media, and another to build optical fibers in microgravity, which prior research has suggested will be superior in quality to those made on Earth.。

The Crew-3 astronauts will also conduct spacewalks to complete an upgrade of the station's solar panels and will be present for two tourism missions, including Japanese visitors aboard a Russian Soyuz spacecraft at the end of the year and the Space-X Axiom crew, set for launch in February 2022.。

Germany arrests two suspects in double police killing******

German police on Monday arrested two suspects in a major manhunt triggered by the fatal shooting of two police officers during a routine traffic stop.

A 38-year-old suspect was taken into custody in the western state of Saarland shortly after police issued a wanted notice and shared his photo with the media.

He was arrested by special forces in the town of Sulzbach, Saarland police said in a statement.

A 32-year-old man was separately detained "without resisting arrest" during police searches of several premises, they added.

The shooting happened at around 4:20 am (0320 GMT) on a rural road in the Kusel district of neighbouring Rhineland-Palatinate state.

A 24-year-old female police officer and her 29-year-old male colleague were killed.

The officers were able to report that they had pulled over a car and that shots were being fired before radio contact broke off.

The shooting, for which the motive remains unclear, sent shockwaves through Germany.

Interior Minister Nancy Faeser likened the crime to an "execution" and said it showed "that police officers risk their lives every day for our security".

The crime triggered a major search operation, with police initially saying they neither had a description of the vehicle in question nor knew in which direction it had sped off.

In an update with the Kaiserslautern prosecution's office on Monday afternoon, police announced they had identified 38-year-old Andreas Johannes Schmitt as a suspect.

A photo shared with reporters showed a brown-haired, bearded man posing for the camera in what appeared to be a bakery.

The suspect was said to hail from Saarland, which borders Luxembourg and France.

German police closed off roads and deployed helicopters and sniffer dogs in the manhunt.

They also urged residents in the Kusel area to avoid picking up hitchhikers.

Saarland police said the twin arrests were the result of "intensive, undercover search methods" carried out jointly with Rhineland-Palatinate police.

German police on Monday arrested two suspects in a major manhunt triggered by the fatal shooting of two police officers during a routine traffic stop.

Still in training

The early morning shooting occurred on a country road surrounded by forest and fields.

The two officers were both in uniform but were patrolling in an unmarked car.

After radio contact was lost, backup police arrived at the scene and found one officer dead and the other fatally injured.

The young woman who was gunned down was still in police training, according to Rhineland-Palatinate Interior Minister Roger Lewentz.

Germany's Bild newspaper quoted unnamed sources as saying the two officers had pulled over a "suspicious vehicle" and radioed in to say they had found dead game in the trunk, before shots were fired.

The female police officer's gun was found still in its holster, according to Bild, suggesting she had not had time to open fire.

Her colleague managed to draw his weapon before being killed, Bild added.

Germany's GdP police union expressed "deep shock and sadness" over the shooting.

The last time a police officer was killed on duty in Rhineland-Palatinate state was in 2010, when a special task force officer was shot dead by a Hells Angels biker during a raid.
