A NASA mission is due to land in the US with “pristine” samples from an asteroid which scientists warned could one day hit Earth.
The OSIRIS-REx spacecraft gathered rocks and dust from the Bennu asteroid’s surface in 2020.
The spacecraft was launched in 2016 as part of NASA’s first mission to collect samples from an asteroid.
It will land with the sample in the Utah desert on Sunday.
NASA has said the “pristine material from Bennu” will offer generations of scientists a window into the time when the sun and planets were forming about 4.5 billion years ago.
Bennu, which was discovered by NASA in 1999, is thought to have been around within the first 10 million years of our solar system’s formation.
It has a diameter of around 490m (1,600ft), weighs 85.5 million tonnes, and is covered in boulders of rock.
The OSIRIS-REx spacecraft briefly touched the surface of Bennu and collected a sample before propelling off the asteroid in October 2020.

Could Bennu ever hit Earth?

Bennu passes near Earth every six years and has had three close encounters with the planet in 1999, 2005, and 2011, NASA has said.
In 2021, scientists with the OSIRIS-REx team said the asteroid could possibly drift into the Earth’s orbit and hit the planet by September 2182.

There is a 1 in 2,700, or 0.037% chance that Bennu could hit Earth in that year, scientists said.
The asteroid would release 1,200 megatons of energy, around 24 times the energy of the most powerful nuclear weapon ever built, if it hit the Earth, according to IFLScience.
However, this is substantially less than the six-mile wide asteroid which killed the dinosaurs – which scientists said in 2019 was as powerful as 10 billion atomic bombs.
Donald Trump has said he would try to return territory to Ukraine as he prepares to meet Vladimir Putin and lay the groundwork for a deal to bring an end to the war.
“Russia has occupied a big portion of Ukraine. They’ve occupied some very prime territory. We’re going to try and get some of that territory back for Ukraine,” the US president said at a White House news conference ahead of Friday’s summit in Alaska.
Mr Trump also said: “There’ll be some land swapping going on. I know that through Russia and through conversations with everybody, to the good of Ukraine.”
He said he’s going to see what Mr Putin “has in mind” to end the three-and-a-half-year full-scale invasion.

And he said if it’s a “fair deal,” he will share it with European and NATO leaders, as well as Volodymyr Zelenskyy, who have been liaising closely with Washington ahead of the meeting.
Asked if Mr Zelenskyy was invited to the summit with Mr Putin in Alaska, Mr Trump said the Ukrainian leader “wasn’t a part of it”.
“I would say he could go, but he’s gone to a lot of meetings. You know, he’s been there for three and a half years – nothing happened,” Mr Trump added.

The US president said Mr Putin wants to get the war “over with” and “get involved” in possible talks but acknowledged Moscow’s attacks haven’t stopped.
“I’ve said that a few times and I’ve been disappointed because I’d have a great call with him and then missiles would be lobbed into Kyiv or some other place,” he said.
Mr Trump said he will tell Mr Putin “you’ve got to end this war, you’ve got to end it,” but that “it’s not up to me” to make a deal between Russia and Ukraine.

Zelenskyy says Russia ‘wants to buy time’
Ukrainian President Volodymyr Zelenskyy has said Russia “wants to buy time, not end the war”.
“It is obvious that the Russians simply want to buy time, not end the war,” he wrote in a post on X, after a phone call with Canada’s Prime Minister Mark Carney.

“The situation on the battlefield and Russia’s wicked strikes on civilian infrastructure and ordinary people prove this clearly.”
Mr Zelenskyy said the two “agreed that no decisions concerning Ukraine’s future and the security of our people can be made without Ukraine’s participation”, just as “there can be no decisions without clear security guarantees”.
Sanctions against Russia must remain in force and be “constantly strengthened,” he added.
European leaders meet ahead of call with Trump
Meanwhile, European officials have been holding meetings ahead of a phone call with Mr Trump on Wednesday.
The European Union’s foreign policy chief, Kaja Kallas, has been speaking to foreign ministers virtually, saying on X that work “on more sanctions against Russia, more military support for Ukraine and more support for Ukraine’s budgetary needs and accession process to join the EU” is under way.

‘Russians want to carry on fighting’
Over the weekend, European leaders released a joint statement, welcoming Mr Trump’s “work to stop the killing in Ukraine”.
“We are convinced that only an approach that combines active diplomacy, support to Ukraine and pressure on the Russian Federation to end their illegal war can succeed,” read the statement.
It was signed by UK Prime Minister Sir Keir Starmer, French President Emmanuel Macron, Italian Prime Minister Giorgia Meloni, German Chancellor Friedrich Merz, Polish Prime Minister Donald Tusk, Finland’s President Alexander Stubb, and European Commission President Ursula von der Leyen.
“We underline our unwavering commitment to Ukraine’s sovereignty, independence and territorial integrity,” they said.
Despite Donald Trump’s efforts to convince Vladimir Putin to commit to a ceasefire and negotiations, Russian attacks on Ukraine have only intensified in the past few months.
Ukraine’s president has said that, in the past week, Russia launched more than 1,000 air bombs, nearly 1,400 drones and multiple missile strikes on Ukraine.
On 9 July, Russia carried out its largest aerial attack on Ukraine since the start of the war, launching more than 740 drones and missiles, breaking its records from previous weeks.
Furthermore, Mr Zelenskyy has said Russia is preparing for new offensives.
He described it as a “feel out” meeting “to see what the parameters” are, and stressed “it’s not up to me to make a deal.”
A strategic preemption perhaps, setting expectations low, and preparing the public for failure.
But he remains wedded to the notion that “land swapping” will shape any deal to end the war in Ukraine.
“Good stuff” and “bad stuff” for both sides, he said, positioning himself as the pragmatic mediator between the two.
He expressed irritation with Mr Zelenskyy’s assertion that he doesn’t have the constitutional power to concede land, though did say he hopes to get “prime territory” back for Ukraine.

The dealmaker-in-chief
Mr Trump promised to brief the Ukrainian president and European leaders immediately after his meeting with Mr Putin.
And he voiced confidence in his ability to quickly assess the potential for a deal, boasting his business acumen.
“At the end of the meeting, probably the first two minutes, I’ll know exactly whether or not a deal can be made,” he said.
Asked how he would know, he replied: “That’s what I do, make deals.”
Donald Trump has announced he is going to deploy National Guard troops to Washington DC to make the US capital’s streets safer.
At a White House news conference on Monday, the president said the city’s police would come under federal control as he said the murder rate in DC was “higher than” in some of the “worst places on earth”.
He said he was sending in the troops to “re-establish law, order, and public safety”.

Mr Trump said he was announcing a “historic action to rescue our nation’s capital from crime, bloodshed, bedlam and squalor and worse.
“This is liberation day in DC and we are going to take our capital back.”
The president continued: “So today we are declaring a public safety emergency in the district of Columbia.”
He added it is not just about safety but also the “beautification” of the city.

“Washington DC should be one of the safest, cleanest and most beautiful cities anywhere in the world and we’re going to make it that.”
Last week, the Republican president directed federal law enforcement agencies to increase their presence in Washington for seven days, with the option “to extend as needed”.

On Friday night, federal agencies including the Secret Service, the FBI and the US Marshals Service assigned more than 120 officers and agents to assist in Washington.
National Guard troops usually belong to individual states and personnel in many cases are trained to help with emergencies that those states have to deal with, such as natural disasters.
Since they are the reserve force of the US military, National Guard troops are usually part-time, meaning that they have other jobs as well.
Minority leader of the US House of Representatives, Hakeem Jeffries, responded to Mr Trump’s announcement on Monday with a post on X which read: “Violent crime in Washington, DC is at a thirty-year low.
“Donald Trump has no basis to take over the local police department. And zero credibility on the issue of law and order.
“Get lost.”
In a social media post on Sunday, Mr Trump emphasised the removal of Washington’s homeless population, though it was unclear where the thousands of people would go.

“The Homeless have to move out, IMMEDIATELY,” Mr Trump wrote.
“We will give you places to stay, but FAR from the Capital. The Criminals, you don’t have to move out. We’re going to put you in jail where you belong.”
