NASA's Perseverance rover launched on a journey to Mars Thursday to hunt for signs of past alien life on the Red Planet.

Why it matters: The rover is the third spacecraft lofted to Mars this month, with the first two sent by the United Arab Emirates and China.

Details: The car-sized rover launched atop a ULA Atlas V rocket at 7:50 a.m. ET from Cape Canaveral, Florida.

  • The rover is now separated from the top of the rocket and is on its way to Mars.

The big picture: Once Perseverance makes it to its landing site in Jezero Crater in about seven months, the rover will set out on a mission to investigate interesting rocks for possible signatures of biology and life.

  • Scientists think the area of Mars that Perseverance will investigate is actually the remnant of an ancient lake and delta rich in deposits that might help preserve signs of life.
  • The rover's instruments will record sound, take photos and use a laser to analyze the chemical compositions of interesting rocks the rover comes across.
  • Perseverance will also cache small samples of rock and dirt in tubes to one day be delivered back to Earth on a future robotic mission.

Some fun things: Perseverance is carrying 10.9 million names submitted by people to the Red Planet etched into three silicon chips.

  • The rover also comes equipped with a plate honoring the first responders on the frontlines of the novel coronavirus pandemic.
  • And a small helicopter called Ingenuity is hitching a ride to Mars to prove out new technology for future missions.

What's next: China's Mars mission, the UAE's Hope orbiter and Perseverance are all expected to make it to the Red Planet in February.

  • The three missions, all designed to perform different tasks to piece together Martian history, will help contribute to a more holistic picture of our cosmic neighbor.

Perseverance will carry new tech to Mars that represents major technological advances since NASA's last rover — Curiosity — landed on the Red Planet in 2012.

Why it matters: These new experiments and technology demonstrations will fill in gaps in knowledge scientists have about the world and set up future robotic missions in the process.

Rep. Rice demands Cuomo resign after third woman accuses him of misconduct

Rep. Kathleen Rice (D-N.Y.) on Monday evening called for New York Gov. Andrew Cuomo (D) to resign, after a third woman accused him of inappropriate behavior.

Driving the news: Anna Ruch told the New York Times Monday that Cuomo asked to kiss her at a New York City wedding reception in September 2019.

Scoop: Inside the GOP's plan to retake the House

House Republicans will reclaim their majority in 2022 by offering candidates who are women, minorities or veterans, a memo obtained by Axios says.

Why it matters: The document, drafted by a super PAC blessed by House Minority Leader Kevin McCarthy, names top Democrats to target — Jared Golden of Maine, Matt Cartwright of Pennsylvania and Ron Kind of Wisconsin — and the type of Republican candidates to beat them.
