NASA has chosen two new missions to unlock the mysteries of Earth's evil twin: Venus.
Why it matters: This marks the first time the space agency will send dedicated missions to the cloudy planet in more than 30 years.
What's happening: The agency announced Wednesday it plans to launch both the DAVINCI+ and VERITAS missions to Venus between 2028 and 2030.
- DAVINCI+ is designed to learn about the composition of the planet's thick atmosphere to assess how it has changed over time and whether the world once played host to oceans.
- The spacecraft will also drop a probe into the planet's atmosphere to collect data about why the world's runaway greenhouse effect took off.
- VERITAS, on the other hand, is expected to use a special kind of radar imager to peer through the planet’s clouds and map Venus’ surface to confirm whether the planet has active plate tectonics or volcanism.
What they're saying: "This is, to my knowledge, an unprecedented decision by NASA: to pick two missions to a single world, designed to take complementary measurements to understand the past climate and present activity of the Earth-size world next door... is absolutely remarkable," planetary scientist Paul Byrne told Axios via Twitter. "We are going to learn things we haven't even thought of yet."
- "We hope these missions will further our understanding of how Earth evolved, and why it's currently habitable and others and our solar system are not," NASA administrator Bill Nelson said during a press briefing.
Transcripts show George Floyd told police "I can't breathe" over 20 times
Section2Newly released transcripts of bodycam footage from the Minneapolis Police Department show that George Floyd told officers he could not breathe more than 20 times in the moments leading up to his death.
Why it matters: Floyd's killing sparked a national wave of Black Lives Matter protests and an ongoing reckoning over systemic racism in the United States. The transcripts "offer one the most thorough and dramatic accounts" before Floyd's death, The New York Times writes.
The state of play: The transcripts were released as former officer Thomas Lane seeks to have the charges that he aided in Floyd's death thrown out in court, per the Times. He is one of four officers who have been charged.
- The filings also include a 60-page transcript of an interview with Lane. He said he "felt maybe that something was going on" when asked if he believed that Floyd was having a medical emergency at the time.
What the transcripts say:
- Floyd told the officers he was claustrophobic as they tried to get him into the squad car.
- The transcripts also show Floyd saying, "Momma, I love you. Tell my kids I love them. I'm dead."
- Former officer Derek Chauvin, who had his knee on Floyd's neck for over eight minutes, told Floyd, "Then stop talking, stop yelling, it takes a heck of a lot of oxygen to talk."
