Osiris-Rex: Nasa confirms return of asteroid Bennu samples
Dusty samples from the “most dangerous known rock in the Solar System” have been brought to Earth.
The American space agency Nasa landed the materials in a capsule that came down in the West Desert of Utah state. The samples had been scooped up from the surface of asteroid Bennu in 2020 by the Osiris-Rex spacecraft.
Nasa wants to learn more about the mountainous object, not least because it has an outside chance of hitting our planet in the next 300 years. But more than this, the samples are likely to provide fresh insights into the formation of the Solar System 4.6 billion years ago and possibly even how life got started on our world.
There was jubilation when the Osiris-Rex team caught sight of their capsule on long-range cameras.
Touchdown on desert land belonging to the Department of Defense was confirmed at 10:52 local time (14:52 GMT), three minutes ahead of schedule.
The car-tyre-sized container had come screaming into the atmosphere over the western US at more than 12km/s (27,000mph). A heatshield and parachutes slowed its descent and dropped it gently, perfectly on to restricted ground.
“This little capsule understood the assignment,” said Tim Priser, the chief engineer at aerospace manufacturer Lockheed Martin. “It touched down like a feather.”
Cleanliness was the watchword out in the desert. When the recovery teams caught up with the capsule on the ground, their objective was to bring it back to a temporary clean room at the nearby Dugway army base as quickly as possible.
If, as researchers think, the sample contains carbon compounds that may have been involved in the creation of life then mixing the rocky material with present-day Earth chemistry has to be avoided.
“The cleanliness and preventing contamination of the spacecraft has been a really stringent requirement on the mission,” said Mike Morrow, the Osiris-Rex deputy project manager. “The best way that we can protect the sample is just to get it from the field into the clean lab that we’ve set up here in a hangar as quickly as possible and get it under a pure nitrogen gas purge. And then it’s safe.”
This was achieved just before 13:00 local time, a mere four hours after touchdown. The lab team disassembled the capsule, removing its heat-shield and back cover but leaving the sample secure inside an inner canister.

Tharanga storms past 92m in Zurich
World-leading javelin thrower Rumesh Tharanga underlined his status as the man to beat in world athletics with another sensational performance, winning the men’s javelin at the prestigious Weltklasse meeting in Zurich with a massive 92.07 metres.
Tharanga’s best effort came in the final round and left him just 21 centimetres short of the meeting record of 92.28m, which has stood for three decades.
The 23-year-old first overcome first round challenge from two-time world champion Anderson Peters of Grenada. Peters took the early lead with a first-round throw of 86.93m, but Tharanga responded in the second round with 88.23m to move ahead.
He then increased his advantage in the third round before producing his best effort of the night in the final round, sending the javelin soaring to 92.07m.
Peters had to settle for second with 86.93m, while Poland’s Dawid Wegner was third with 85.16m. Trinidad and Tobago’s Keshorn Walcott finished fourth with 83.02m, followed by Kenya’s Julius Yego (81.66m) and American Marc Anthony Minichello (80.38m).
The Zurich victory further strengthens Tharanga’s position at the top of the world javelin hierarchy at a crucial stage of the season. With the Wanda Diamond League Final in Brussels just a week away and the World Athletics Ultimate Championship looming, he has emerged as the athlete everyone will be watching.
Tharanga’s latest 92-metre-plus throw also provides a timely reminder of his extraordinary consistency at the highest level, as he continues his remarkable rise among the world’s elite javelin throwers. (RF)

Iran, Qatar hold Hormuz talks amid int’l hopes dialogue with US will resume
Qatar’s prime minister has held meetings in the Iranian capital, discussing key issues including the future of the Strait of Hormuz, amid international hopes that dialogue between the United States and Iran on ending the war will resume.
Iran’s Foreign Minister Abbas Araghchi and Qatar’s Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani on Thursday discussed a proposed framework that includes the creation of a temporary shipping corridor through the Strait of Hormuz, as well as a possible “joint project” to clear the strait of mines, the Qatari Ministry of Foreign Affairs said in a statement. Iran says the mines were laid during the war.
The two officials also reviewed “the latest developments in the regional situation … along with the efforts being made to reduce escalation and create appropriate conditions for dialogue, contributing to the enhancement of regional security and stability”, the statement added.
Sheikh Mohammed, who is both prime minister and foreign minister of Qatar, later met separately with Iranian President Masoud Pezeshkian and parliament speaker and top negotiator, Mohammad Bagher Ghalibaf.
Ghalibaf emphasised the need to de-escalate regional tensions, according to Iran’s Tasnim news agency. He and Sheikh Mohammed also exchanged views on the current developments in the region and efforts to create suitable conditions for resuming dialogue, the report added.
“Qatar believes that dialogue and diplomatic solutions remain the optimal path for addressing disputes and overcoming crises,” Sheikh Mohammed said in a post on X, adding that his discussions in Tehran serve as “confirmation of our continued efforts to de-escalate tensions … while opening the door to peaceful solutions – including underscoring the importance of respecting freedom of navigation in the Strait of Hormuz in accordance with international law.”
Sheikh Mohammed also met with Iran’s security chief, Mohsen Rezai.
Rezai told him the “US must first take practical steps to fulfil Iran’s conditions and then Iran will proceed to open the Strait of Hormuz”, the Islamic Republic News Agency (IRNA) reported.
Rezai also reiterated previous pledges by Tehran that if Washington “starts any evil”, Iran would “bring disaster to its military and economic interests”.
Sheikh Mohamed’s visit follows a week of intense diplomacy in Iran involving separate meetings with Oman’s Foreign Minister Badr Albusaidi and senior Pakistani officials seeking ways to end the US-Israel war on Iran and reopen the strategic waterway through which about 20 percent of the world’s oil passes in peacetime.
