Watch and listen to Perseverance's first moments on Mars

When NASA's Perseverance rover landed on Mars Thursday, a set of cameras captured the car-sized spacecraft's descent and landing on the Red Planet.

Why it matters: This is the first time this type of high-quality footage has been captured.


Catch up quick: Perseverance landed on Mars in much the same way as its counterpart on the Red Planet, Curiosity.

  • NASA made use of a supersonic parachute and a small rocket that slowed the rover's descent and used cables to softly lower it to the ground.
  • The rover landed in a crater thought to be one of the best places on Mars to hunt for signs of past life.

Driving the news: The cameras tasked with capturing the landing sent back about 30 gigabytes of footage from Perseverance's landing to waiting scientists on Earth.

  • “This video of Perseverance’s descent is the closest you can get to landing on Mars without putting on a pressure suit,” Thomas Zurbuchen, NASA associate administrator for science, said in a statement.
  • Perseverance also recorded the first sounds from Mars not long after making it to the surface.

The big picture: The video and audio captured from Mars has more than just public value. Scientists are also hoping to use both as diagnostic and scientific tools on Mars.

  • Engineers will be able to pour over the landing video from Perseverance to tease out exactly how the system worked on the Red Planet.
  • Future rovers might carry microphones to Mars "because everybody knows that when you hear something squeaking, it's diagnostic," Justin Maki, Perseverance imaging scientist, said during a press conference Monday. "Maybe you need to check it out."

What's next: NASA is planning to continue uploading photos and turning the rover's microphones on as it gets to work on Mars.

  • "I hope it does survive long enough so that we can hear those wheels crunch over the surface of the planet," Matt Wallace, Perseverance deputy project manager, said during the press conference.

Twitter sues Texas AG Ken Paxton, alleging he launched probe in retaliation for Trump ban

Twitter on Monday filed a lawsuit against Texas Attorney General Ken Paxton (R), saying that his office launched an investigation into the social media giant because it banned former President Trump from its platform.

Driving the news: Twitter is seeking to halt an investigation launched by Paxton into moderation practices by Big Tech firms including Twitter for what he called "the seemingly coordinated de-platforming of the President" days after they banned him following the Jan. 6 Capitol insurrection.

Retiring Republicans could clear the path for GOP troublemakers to join the Senate ranks

Sen. Roy Blunt's retirement highlights the twin challenge facing Senate Republicans: finding good replacement candidates and avoiding a pathway for potential troublemakers to join their ranks.

Why it matters: While the midterm elections are supposed to be a boon to the party out of power, the recent run of retirements — which may not be over — is upending that assumption for the GOP in 2022.

Diversity in Congress is growing steadily, but lags behind the U.S. population

Data: Brookings Institution and Pew Research Center; Note: No data on Native Americans in Congress before the 107th Congress; Chart: Danielle Alberti/Axios

The number of non-white senators and House members in the 535-seat Congress has been growing steadily in the past several decades — but representation largely lags behind the overall U.S. population.

Why it matters: Non-whites find it harder to break into the power system because of structural barriers such as the need to quit a job to campaign full time for office, as Axios reported in its latest Hard Truths Deep Dive.

U.S. grants temporary protected status to thousands of Venezuelans

Venezuelans living in the United States will be eligible to receive temporary protected status for 18 months, the Department of Homeland Security announced Monday.

Why it matters: Tens of thousands of Venezuelans have fled to the U.S. amid economic, political and social turmoil back home. Former President Trump, on his last full day in office, granted some protections to Venezuelans through the U.S. Deferred Enforced Departure program, but advocates and lawmakers said the move didn't go far enough.

Supreme Court declines to hear case on qualified immunity for police officers

The Supreme Court on Monday declined to hear an appeal for a lawsuit brought against Cleveland police officers that challenges the scope of qualified immunity, the legal doctrine which has been used to shield officers from lawsuits alleging excessive force, Reuters reports.

Why it matters: The doctrine has been the subject of scrutiny from civil rights advocates. Eliminating qualified immunity was one of the key demands of demonstrators during nationwide protests in 2020 following the killing of George Floyd.
