NASA's Southern California-Built Perseverance Rover Lands on Mars

The Perseverance rover, built in Pasadena at JPL, touched down gently on Mars Thursday after a nearly seven-month journey through space.

What to Know

  • A Southern California-built NASA rover landed on Mars Thursday after a nearly seven-month voyage through space.
  • After a harrowing descent through the Martian atmosphere, the Perseverance rover was lowered to the surface in a skycrane maneuver.
  • The rover began taking photos of its landing spot and, eventually, it will deploy a small helicopter for further exploration.

NASA landed its fifth rover on Mars Thursday after a nearly seven-month journey that ended with a 12,000-mph blast through the Martian atmosphere and a gentle touchdown on the Red Planet.

Moments after touchdown, word came from mission control: "Perseverance is alive on the surface of Mars.

Then, the rover provided a jubilant mission crew with its first image of its landing spot. More will follow in the coming days as the SUV-sized rover begins unpacking its suite of scientific equipment.


Ground controllers at the space agency’s Jet Propulsion Laboratory in Pasadena, California, settled in nervously Thursday morning for the descent of Perseverance to the surface of Mars, long a deathtrap for incoming spacecraft. The craft was to reach speeds of 12,000 mph during its blast through the super-heated Martian atmosphere.

It takes a nail-biting 11 1/2 minutes for a signal that would confirm success to reach Earth. The mission crew conducted a series of high-stakes maneuvers, part of the "seven minutes of terror" that ended with a gentle touchdown on the Martian surface.

The landing of the six-wheeled vehicle marks the third visit to Mars in just over a week. Two spacecraft from the United Arab Emirates and China swung into orbit around the planet on successive days last week. All three missions lifted off in July to take advantage of the close alignment of Earth and Mars, traveling some 300 million miles in nearly seven months.

NASA’s Perseverance rover touched down on Mars in a feat of human engineering and science. But… how does it work? LX News host Tabitha Lipkin helps explain how the rover is built to fulfill its mission to explore Mars and collect samples to return to Earth.

Perseverance, the biggest, most advanced rover ever sent by NASA, became the ninth spacecraft to successfully land on Mars, every one of them from the U.S. It carries a small helicopter, a first for Mars exploration, called Ingenuity that will eventually deploy to provided a whole new view of Mars.

There's a lot onboard the Mars Perseverance rover. NBC4's Belen De Leon takes a look at what's inside.

The plutonium-powered rover was aiming for NASA’s smallest and trickiest target yet: a 5--by-4-mile strip on an ancient river delta full of pits, cliffs and fields of rock.

Scientists believe that if life ever flourished on Mars, it would have happened 3 billion to 4 billion years ago, when water still flowed on the planet.

Among the rover's features is Percy, as it is nicknamed, an arm designed to drill down with its 7-foot (2-meter) reach and collect rock samples that might hold signs of bygone microscopic life. The plan called for three to four dozen chalk-size samples to be sealed in tubes and set aside on Mars to be retrieved by a fetch rover and brought homeward by another rocket ship, with the goal of getting them back to Earth as early as 2031.

Scientists hope to answer one of the central questions of theology, philosophy and space exploration.

“Are we alone in this sort of vast cosmic desert, just flying through space, or is life much more common? Does it just emerge whenever and wherever the conditions are ripe?” said deputy project scientist Ken Williford. “Big, basic questions, and we don’t know the answers yet. So we’re really on the verge of being able to potentially answer these enormous questions.”

China’s spacecraft includes a smaller rover that also will be seeking evidence of life — if it makes it safely down from orbit in May or June.

Perseverance’s descent has been described by NASA as “seven minutes of terror,” in which flight controllers can only watch helplessly. The preprogrammed spacecraft was designed to hit the Martian atmosphere at 12,100 mph (19,500 kph), then use a parachute to slow it down and a rocket-steered platform known as a sky crane to lower the rover the rest of the way to the surface.

Mars has proved a treacherous place: In the span of less than three months in 1999, a U.S. spacecraft was destroyed upon entering orbit because engineers mixed up metric and English units, and an American lander crashed on Mars after its engines cut out prematurely.

NASA is teaming up with the European Space Agency to bring the rocks home. Perseverance’s mission alone costs nearly $3 billion.

Microphones will record the landing and the rocks, seeking evidence of past life on Mars. NBC4 Meteorologist Anthony Yanez reports for the NBC4 News on Wednesday, Feb. 17, 2021.

The only way to confirm — or rule out — signs of past life is to analyze the samples in the world’s best labs. Instruments small enough to be sent to Mars wouldn’t have the necessary precision.

“The Mars sample return project is probably the most challenging thing we’ve ever attempted within NASA,” said planetary science director Lori Glaze, “and we don’t do any of these things alone.”
