Hey, from CNN, I'm Ifeoma Dike with the five things you need to know for Tuesday, June 9th.

President Donald Trump said the US must respond after Iran shot down a US army helicopter off the coast of Oman. The US military said two pilots were rescued by an uncrewed drone boat. Iran's foreign minister has urged U. S. Forces to leave the Strait of Hormuz or be quote, at constant risk. Here's CNN's Kristen Holmes.

So here's what we know so far about the incident itself. An Army Apache was patrolling regional waters when it went down near the coast of Oman. There were two crew members who were rescued by U.S. Forces in two hours. And then, of course, at the time that we got this readout, the cause was still under investigation. We know at least part of that cause is that Iran shot it down, unclear on the intent. We aren't clear if this means military action. President Trump has been pretty clear for the last several weeks that he does not want any kind of increased military action in Iran, but of course, now he is citing this attack. From the Iranians and saying that the US must respond. So, obviously, this is going to put everything that we have heard for the past 24 hours, including President Trump saying that a peace deal was two to three days away, into question.

More news coming up, including the verdict in a school track meeting stabbing trial.

'A jury has convicted a Texas teen of murder, who fatally stabbed a student-athlete from a rival team with a knife during a track meet. The case drew national attention far beyond the Dallas suburb where the two students, Karmelo Anthony and Austin Metcalf, attended different high schools. A jury rejected Anthony's claims of self-defense during a confrontation with Metcals from the stadium's bleachers last year. The 19-year-old Anthony didn't testify. Students who testified described a heated exchange over Anthony refusing to leave a tent belonging to Metcalf's team during a rainy competition. Anthony faces up to life in prison upon sentencing.

Americans could see smaller monthly social security checks in 2032 if Congress doesn't act. The program's retirement trust fund, which helps pay seniors and survivors of deceased workers, is expected to run dry later that year. According to trustees, that's one quarter earlier than previously forecast. Payroll tax revenue and other income sources will only be able to cover 78% of the benefits owed. One reason for the forecast change is due to President Trump's One Big Beautiful Bill Act. Its provisions allow less tax to be paid on Social Security benefits, which means less revenue flowing to the Social Security and Medicare trust funds.

For the first time in 20 years, the FDA approved a new sunscreen ingredient used for years in Europe and Asia. It's called bemaltrizenol. Experts say it's a safer option than many chemical ingredients currently used in the US. A senior scientist says bemaltrisenol provides adequate UVA protection and is not easily absorbed into the skin. While critics say sunscreens in the US today are good at blocking UVB rays that cause visible sunburns instead of UVA rays that are the primary contributor to skin cancer, according to the American Cancer Society. The scientist also says bimitrizenol has the most robust safety data on any UV filter to date.

Coming up, NASA's next big mission.

The Artemis II crew, comrade, hands you the baton. You got the controls.

'NASA has revealed the Artemis III crew that'll take the next step toward a return to the moon for the first time in more than 50 years. It's a four-man team consisting of three Americans and one Italian, and they're set to launch as soon as late next year. Here's CNN's Pete Muntean.

Former test engineer Coast Guard Reserve Commander Andre Douglas will make his first trip to space on Artemis 3. Douglas was selected as an astronaut in 2021. Has been heavily involved in lunar exploration and planning for human landing system development. The other big first here, Italy's Luca Perometino, one of Europe's most experienced astronauts, will be the first European on a moon mission. He will serve as the mission's pilot. Former ISS commanders, flown in space twice, conducted multiple spacewalks during his career. The second mission specialist is Army helicopter pilot and physician, Frank Rubio. He also holds the US record for the longest single space flight. Rubio spent 371 days aboard the International Space Station after an unexpected extension of his mission in 2022 and 2023. And finally, Artemis 3 will be commanded by veteran astronaut Randy Breznik. The former Marine Corps colonel and test pilot has flown in space twice, commanded the International Space Station and logged more than 7,000 flight hours.

That is it for us, we're back tomorrow morning.
