NASA's newly selected Dragonfly mission to Saturn’s largest moon Titan will mark a new way of exploring the solar system for the space agency.

The big picture: Dragonfly's unique design will allow scientists to get a full picture of Titan's various environments over the course of its mission. Instead of staying in one place like a lander or driving along the surface like a rover, Dragonfly will be able to fly through Titan's thick atmosphere, land and then take off again.

  • This kind of mission will allow scientists to piece together whether the moon could be a friendly place for life today or in the past.

Details: Once it arrives at the moon in 2034 after launch in 2026, Dragonfly will descend through the world's atmosphere underneath a parachute before flying free using its 4 rotors and heading to its first destination at Titan's equator.

  • The spacecraft will then land, study the area — which has a number of interesting dunes — and then eventually take off again, taking flights of up to 5 miles, according to NASA.
  • Over the course of its 2.7-year mission, Dragonfly is expected to fly up to 108 miles.
  • The spacecraft will be able to collect and analyze samples from Titan's surface and beam home photographs to Earth while gathering data about the world’s atmosphere during flights.
  • Eventually, mission controllers want the spacecraft to fly to the Selk impact crater where researchers think there could be evidence of all the components needed for life.

Yes, but: There are always risks when trying something new out in the solar system. NASA is planning to draw from technologies that are currently in use on Earth and Mars to make sure Dragonfly has its best chance at a successful mission.

CNN crew arrested live on air while reporting on Minneapolis protests

CNN's Omar Jimenez and his crew were arrested Friday by Minneapolis state police while reporting on the protests that followed the death of George Floyd, a black man who died in police custody in the city.

What happened: CNN anchors said Jimenez and his crew were arrested for not moving after being told to by police, though the live footage prior to their arrests clearly shows Jimenez talking calmly with police and offering to move wherever necessary.

First look: Trump courts Asian American vote amid coronavirus

The president's re-election campaign debuts its "Asian Americans for Trump" initiative in a virtual event tonight, courting a slice of the nation's electorate that has experienced a surge in racism and harassment since the pandemic began.

The big question: How receptive will Asian American voters be in this moment? Trump has stoked xenophobia by labeling COVID-19 the "Chinese virus" and the "Wuhan virus" and equating Chinatowns in American cities to China itself.

How the U.S. might distribute a coronavirus vaccine

Now that there are glimmers of hope for a coronavirus vaccine, governments, NGOs and others are hashing out plans for how vaccines could be distributed once they are available — and deciding who will get them first.

Why it matters: Potential game-changer vaccines will be sought after by everyone from global powers to local providers. After securing supplies, part of America's plan is to tap into its military know-how to distribute those COVID-19 vaccines.
