NASA’s Mars 2020 Perseverance rover mission: Live updates



Post-landing update coming soon from NASA

Pasadena, Calif. — PERSEVERANCE LANDED! Here at JPL, scientists, engineers, administrators and members of the media (like me) are cheering and celebrating. It’s almost unbelievable that it’s real, it’s so exciting to see the joy here at JPL, the Mars2020 team could not be more thrilled about how today went and where this mission is headed.

NASA will hold a press conference at 5:30 p.m. EST (2230 GMT) to discuss how the landing went. You can watch it live here on Space.com, courtesy of NASA TV.

The “7 minutes of terror” start NOW!

The Perseverance rover hit the top of the Martian atmosphere at 3:48 p.m. EST (2048 GMT), marking the beginning of the entry, descent and landing sequence, which NASA calls the “seven minutes of terror.” The rover is expected to touch down in Jezero Crater at around 3:55 p.m. EST (2055 GMT).

But keep in mind: These are the times that mission controllers in NASA’s Jet Propulsion Laboratory will receive signals from Mars confirming that these events have taken place. Because the radio transmissions travel at the speed of light and communications are not instantaneous, it takes about 11 minutes and 22 seconds for a signal to travel from Mars to Earth. This means that the “seven minutes of terror” actually started at 3:37 p.m. EST (2037 GMT).

“The team of engineers that piloted NASA’s Mars 2020 spacecraft, with the Perseverance rover and NASA’s Ingenuity Mars Helicopter inside, during the cruise from Earth to the Red Planet has handed over the reins to the entry, descent, and landing (EDL) team,” NASA officials said in an update

Next stop: MARS! 


The landing is looking good from NASA JPL

Pasadena, Calif. — Space.com senior writer Chelsea Gohd here reporting LIVE from NASA’s Jet Propulsion Laboratory, where the agency’s Mars 2020 team is hard at work getting its Perseverance rover down to the Red Planet’s surface. 

All around me are scientists, engineers and other NASA personnel who have been bustling around campus all morning, masked up and socially distanced for safety during the ongoing coronavirus pandemic. I spoke with a few of them, including Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate, who shared how proud he is of the teams that made today’s landing possible despite the challenges that the pandemic threw their way.

The excitement in the air is palpable and I even saw a few people walking into buildings toting boxes of Krispy Kreme doughnuts (containing what I can only assume are the new Mars-themed treats the company rolled out just for today’s landing). 

I am holding my breath as we have just about an hour until the rover lands in Jezero Crater on the Martian surface. Keeping my fingers crossed and eagerly anticipating celebrating a successful landing. 


Perseverance rover ready to land on Mars

NASA’s live webcast for today’s Perseverance Mars rover is under way. You can watch it live above. 

Perseverance’s flight controllers have switched off the rover’s transmitter, leaving it on its own for today’s landing. From here on out, Perseverance will be flying by its onboard computer. 

It’s next stop: Jezero Crater. 


NASA science chief talks Mars landing

NASA’s Perseverance rover is just hours away from landing on Mars and Space.com’s Chelsea Gohd caught up with the Thomas Zurbuchen, NASA’s Associate Administrator for science missions, to find out how the mission team is feeling. 

It’s safe to say the team is excited, and maybe a bit anxious. 

Once Perseverance lands on Mars, the engineers and scientists running the mission will have to work on “Mars time” for a while. That means they’ll have to work, live and sleep on the daily schedule on Mars, which has a longer day than the Earth. Here’s how life on “Mars Time” works for NASA.

Less than 24 hours til touchdown!

In less than 24 hours, NASA’s latest rover, named Perseverance, will land on the Red Planet as part of the agency’s Mars 2020 mission. 

The rover will touch down at 3:55 p.m. EST (2055 GMT) on Feb. 18, if everything goes according to plan. 

Perseverance, nicknamed “Percy,” is an ambitious rover, slightly bigger and heavier than the Curiosity rover, with an impressive suite of instruments and experiments. With its tools, “Percy” will cache samples to be returned by a future mission as part of the first-ever Mars sample return mission. It will also search for signs of ancient life on the planet, which is why scientists decided to land the craft in Jezero Crater, which once held an ancient lake and delta, where they think life could have existed billions of years ago. 

“Percy” will also deploy Ingenuity, a Mars helicopter stored in its belly, which is set to make the first powered flight on another world, an “extraterrestrial Wright brothers moment,” Thomas Zurbuchen, NASA associate administrator for science at NASA Headquarters, said during the news conference Feb. 16. 

You can follow the action in (almost) real-time as NASA will provide coverage of the event beginning at 2:15 p.m. EST (1715 GMT) Feb. 18. You can watch it live here at Space.com, courtesy of NASA, or directly at NASA TV.

Perseverance closes in on Mars

Perseverance’s journey through interplanetary space is nearly over. The rover is now just three weeks away from its long-awaited touchdown on the floor of Mars’ Jezero Crater.

NASA is riding an impressive streak of successful Mars landings (knock on wood), but you can’t take Perseverance’s touchdown for granted.

“Success is never assured,” Allen Chen of NASA’s Jet Propulsion Laboratory in Southern California, the entry, descent, and landing lead for Perseverance’s mission, said on Wednesday (Jan. 27). “And that’s especially true when we’re trying to land the biggest, heaviest and most complicated rover we’ve ever built in the most dangerous site we’ve ever attempted to land in.”

After blasting off on July 30, NASA’s Mars 2020 Perseverance rover is on its way to Jezero Crater on the Red Planet where it’s scheduled to land Feb. 18, 2021. Now, thanks to a new, interactive NASA web application called Eyes on the Solar System, you can follow the industrious spacecraft on its interplanetary journey. 

“Eyes on the Solar System visualizes the same trajectory data that the navigation team uses to plot Perseverance’s course to Mars,” Fernando Abilleira, the Mars 2020 mission design and navigation manager at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, said in a statement. “If you want to follow along with us on our journey, that’s the place to be.”

Rover-naming teens are “over the moon”

July 30, NASA’s Mars 2020 Perseverance rover successfully lifted off from Earth, bound for the Red Planet, where it is set to land Feb. 18, 2021. Of the many people excited to see the rover lift off, two teenagers watching the launch in Florida had a special connection. These two teens actually named the rover and its onboard helicopter. 

Alex Mather, a 7th-grade student from Virginia, and Vaneeza Rupani, a high-school senior from Alabama, named the Perseverance rover and the helicopter Ingenuity, respectively.

Spotting Percy en route to Mars

Since NASA’s Mars 2020 Perseverance rover launched to the Red Planet July 30, both a weather satellite and a robotic telescope have spotted the craft on its way to its dusty destination. 

The weather satellite GOES-16 spotted the smoke plume coming from the Florida launch and The Virtual Telescope Project spied the booster from the Atlas V rocket which launched the rover-holding spacecraft.

Mars rover Perseverance out of ‘safe mode’

NASA’s Mars rover Perseverance, which went into a protective “safe mode” shortly after its launch yesterday, is back to normal operations and cruising toward the Red Planet. 

In an announcement today, July 31, NASA officials reported that Perseverance is healthy and out of “safe mode” following a temperature variance that prompted the rover’s onboard computer to enter the protective state. The spacecraft got a bit colder than expected when it zoomed through Earth’s shadow.

“With safe mode exit, the team is getting down to the business of interplanetary cruise,” Mars 2020 deputy project manager Matt Wallace, of NASA’s Jet Propulsion Laboratory in Pasadena, California, said in an update. “Next stop, Jezero Crater.”

You can read our full story here.

Here is full explanation of the issue by Wallace in a previous NASA update on July 30:

“First, the proximity of the spacecraft to Earth immediately after launch was saturating the ground station receivers of NASA’s Deep Space Network. This is a known issue that we have encountered on other planetary missions, including during the launch of NASA’s Curiosity rover in 2011. The Perseverance team worked through prepared mitigation strategies that included detuning the receivers and pointing the antennas slightly off-target from the spacecraft to bring the signal within an acceptable range. We are now in lock on telemetry after taking these actions.

“The second issue was a transient event involving temperature on the spacecraft. The mission uses a liquid freon loop to bring heat from the center of the spacecraft to radiators on the cruise stage (the part that helps fly the rover to Mars), which have a view to space. We monitor the difference in temperature between the warm inlet to the radiators and the cooler outlet from the radiators. As the spacecraft entered into Earth’s shadow, the Sun was temporary blocked by Earth, and the outlet temperature dropped. This caused the difference between the warm inlet and cooler outlet to increase. This transient differential tripped an alarm and caused the spacecraft to transition into the standby mode known as ‘safe mode.’

“Modeling by the team predicted something like this could happen during eclipse – the time when the spacecraft is in Earth’s shadow – but we could not create this exact environment for tests prior to launch. Nor did we have flight data from Curiosity, because its trajectory had no eclipse. We set the limits for the temperature differential conservatively tight for triggering a safe mode. The philosophy is that it is far better to trigger a safe mode event when not required, than miss one that is. Safe mode is a stable and acceptable mode for the spacecraft, and triggering safe mode during this transitional phase is not problematic for Mars 2020.

“With the understanding of the causes of these issues, we are conducting the operations necessary to move the spacecraft back out of safe mode and into normal cruise mode.”


Percy’s first day to Mars

Today (July 31), NASA’s Mars 2020 Perseverance rover begins its first full day in its roughly seven-month trip to the Red Planet. Perseverance, or “Percy,” is now one of three craft traveling to Mars and slated to arrive in February 2021. 

The first to launch was the United Arab Emirates’ “Hope” orbiter, the second was China’s Tianwen-1 orbiter/lander/rover combined mission and now, Percy is well on its way to Mars where it will land in an ancient Martian Lake — Jezero Crater.

However, is this a space race to Mars? Not quite — here’s why.

While Hope will orbit Mars and Tianwen-1 will attempt to orbit around, land on the planet and explore, Percy will study Mars in a number of unique ways. One of the things Percy will do that has never been done before is the rover will cache samples of Martian material that will be picked up and transported to Earth with a future mission.

Update on Perseverance rover in Safe Mode

Space.com has new details on the Perseverance Mars rover’s “safe mode” event that occurred shortly after launch. 

Matt Wallace, deputy project manager for Mars 2020 with NASA’s Jet Propulsion Laboratory, told Space.com contributor Amy Thompson at the Kennedy Space Center in Cape Canaveral, Florida, that Perseverance’s safe mode condition has been traced to temperature fluctuations in the cooling system for its nuclear battery. Here’s her report: 

The rover’s power source is a nuclear powered generator known as an MMRTG. It’s attached to the rover, which is cocooned inside the entry capsule of the vehicle. When the rover is out in the breeze on the Martian surface, it’s fine. However, when it’s in the entry capsule (which will protect Perseverance during entry, descent and landing on Mars), things can get a bit warm. 

The Mars 2020 rover's power system, called a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG), will be inserted into the aft end of the rover between the white panels with gold tubing.

To help mitigate this issue, the vehicle relies on a cooling system that pumps freon from the MMRTG to a set of radiators. While this process is cycling, computers monitor the temperature differences to make sure the rover stays within preset parameters. 

As the spacecraft transitioned into its brief eclipse period — a part of its flight when the sun is being blocked by the Earth — that temperature difference increased rapidly, triggering the craft to enter safe mode.  

Wallace explained that since engineers cannot duplicate the space environment here on Earth, they estimate what the temperatures should be and set very conservative parameters. 

“Unfortunately, our analysis is never really perfect,” he told Space.com. “Curiosity didn’t have an eclipse in its flight trajectory so we didn’t have flight data to know what was going to happen.”

“The spacecraft was never in jeopardy,” he added. “Our philosophy is to be overly conservative on the parameters because we’d much rather trigger a safing event we didn’t need, than miss a safing event we do need.”

The team will continue to analyze the telemetry data that the vehicle has sent so far and double check that this is indeed the hiccup. Once that is complete, the team can put the rover back in an operational status.

Wallace says he expects for the spacecraft to return to normal operations mode tomorrow (July 31). But the team is not in any rush and are taking their time to carefully review all the data. Wallace says there’s plenty of time before the next big phase of the mission.  


Perseverance rover in ‘safe mode’ after launch

NASA officials just confirmed that the Mars 2020 Perseverance rover entered a protective “safe mode” after its launch today due to an unexpected temperature condition on the spacecraft. 

The rover’s launch was successful, with Perseverance on the right path to Mars. But shortly after liftoff, telemetry indicated the rover entered a “safe mode” due to unexpectedly cold temperatures, NASA officials said. 

“Data indicate the spacecraft had entered a state known as safe mode, likely because a part of the spacecraft was a little colder than expected while Mars 2020 was in Earth’s shadow,” NASA officials said in a statement. “All temperatures are now nominal and the spacecraft is out of Earth’s shadow.”

“Safe mode” is a protective state for spacecraft and rovers in which they shut down non-essential systems until receiving new commands from Earth. 

“An interplanetary launch is fast-paced and dynamic, so a spacecraft is designed to put itself in safe mode if its onboard computer perceives conditions are not within its preset parameters,” NASA officials wrote in the statement. “Right now, the Mars 2020 mission is completing a full health assessment on the spacecraft and is working to return the spacecraft to a nominal configuration for its journey to Mars.”


Mars rover Perseverance mission in good health

NASA’s Mars rover Perseverance post-launch briefing has ended. The rover is in good shape after launch, even as flight controllers work on a minor communications issue related to the rover’s stronger-than-expected signal strength, NASA officials said.

Read our launch wrap story here!

Thomas Zurbuchen, NASA associate administrator for science missions, said he’s thrilled with the launch. 

“I’m relieved. It’s a space mission now,” Zurbuchen said. The communications glitch is something the rover team is working on, but that’s part of the job when it comes to space missions, he added. 

Here’s some more amazing launch photos.

Matt Wallace, NASA’s deputy project manager for Perseverance, said Perseverance may have experienced a  “temperature transient” event after launch that could have placed its computer in a protective safe mode, but more time is needed to confirm the telemetry. It should take about an hour to wrap that up, he said. 

In the meantime, Perseverance has now begun a 6.5-month cruise to Mars. This concludes on launch coverage, but updates will be posted as news on Perseverance is available throughout the mission. 

Thanks for joining us!


NASA gets Perseverance rover telemetry

NASA’s post-launch press conference for the Perseverance rover is under way. 

Matt Wallace, NASA’s deputy project manager for Perseverance, reports that the Deep Space Network has established a telemetry lock with the rover. As of 11:50 a.m. EDT (1550 GMT), it should take about 30 to 60 minutes to verify the rover’s condition, but all signs point to good health, Wallace said. 

Perseverance’s signal is extremely strong, and a bit overwhelming for the Deep Space Network’s sensitive receiver. A similar issue occurred after the Curiosity rover launch in 2011, he said. The signal is being modulated so the DSN can process it, he added.


Signal issues

Shortly after signal acquisition, NASA teams had an issue with matching signal strengths between the spacecraft and ground stations. However, this is seen as a temporary issue and one that is not only easily solvable, but that has been solved before, NASA Administrator Jim Bridenstine shared on Twitter. 

“We had a good launch this morning, we’re right on course for Mars and signal from @NASAPersevere is strong. We are working to configure the ground stations to match the strength of the spacecraft signal. This scenario is one we’ve worked through in the past with other missions,” Bridenstine tweeted

Perseverance is also carrying a meteorite from Mars back to Mars as part of an experiment, according to collectSPACE.com editor Robert Pearlman. Pearlman also brings us this story about a piece of spacesuit material on Perseverance, which NASA  will use to test spacesuit technology for future astronaut missions.

Space.com’s Chelsea Gohd took a look at how Perseverance will help the search for life on Mars. Check it out here

Meanwhile, our senior writer Meghan Bartels dives in to the history of nuclear power on Mars and across the solar system. You can read that powerful story (see what we did there) here.

Finally, if you missed Space.com’s Summer of Mars panel today, don’t fret. You can catch the replay with Jim Watzin, director of NASA’s Mars Exploration Program, and Jim Bell, President of the Planetary Society. Check that out here.


NASA’s Dr. Z talks Mars rover Perseverance

We caught up with Dr. Thomas Zurbuchen, the Associate Administrator for the Science Mission Directorate at NASA, one day before NASA’s Mars 2020 Perseverance rover takes off for the Red Planet.  

In the video chat (check it out above!) he detailed the incredibly innovative tools that Perseverence, nicknamed “Percy,” will carry to Mars and what makes the rover and mission so unique and important. He also highlighted some of his favorite aspects of the mission, which will collect and cache samples that researchers hope will be carried to Earth with a future mission.


One day from launch

We are less than 24 hours away from the launch of NASA’s Mars 2020 Perseverance rover! The rover will scour Mars for signs of ancient, microbial life. 

Tomorrow at 7:50 a.m. EDT (1150 GMT), Percy will begin its journey to the Red Planet aboard a United Launch Alliance Atlas V rocket which will launch from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

It’s time to get excited and prepare yourself to watch and enjoy the historic launch.

Today, you can hear NASA Administrator Jim Bridenstine’s thoughts about the Mars-bound mission in a live-streamed video on NASA Live, which will begin at noon EST (1600 GMT.)

Also today, beginning at the same time, you can join Space.com for our “Summer of Mars” webinar, in which you’ll be able to connect with the Space.com community to discuss and learn about Perseverance, Mars, the search for life and so much more. 

Go here for up-to-date information on how to watch the launch tomorrow live.

Perseverance, formerly known as the Mars 2020 rover, passed its launch readiness review, NASA officials announced today (July 27.) This was the last major hurdle before the rover is launched on Thursday (July 30) and so, with a pretty good weather forecast and this major obstacle behind it, the mission is making serious progress towards the Red Planet.
