Not obstacles, not complexity — not even a worldwide pandemic — could keep NASA’s Mars 2020 Perseverance rover from blasting off on its historic mission to the Red Planet.

On Thursday, July 30, at 7:50 a.m. EDT, Perseverance lifted off aboard a United Launch Alliance (ULA) Atlas V 541 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, bound for a Feb. 18, 2021, arrival to Mars, where it will touch down on the surface of Jezero Crater.

“It was an amazing launch; very successful,” NASA Administrator Jim Bridenstine said during Thursday’s post-launch news conference at NASA’s Kennedy Space Center in Florida. “It went right on time, it is on a trajectory now that has been done with pinpoint accuracy, and it is, in fact, on its way to Mars.”

Due to the alignment of Earth and Mars, the mission’s launch period would have expired on Aug. 15. That placed increased importance on hitting the window; otherwise, the rover would have needed to be stored for two years, until the next favorable alignment.

“(The ULA and Launch Services team) gave us a perfect launch this morning — right down the middle; couldn’t have aimed us any better,” said Matt Wallace, deputy project manager at NASA’s Jet Propulsion Laboratory. “They really pushed hard to keep us on this limited planetary launch window in 2020.”

With its unique and distinct challenges, COVID-19 certainly threatened that timeline. Wallace admitted there have been “very strenuous moments” in the past few months dealing with the pandemic.

“It really took the entire agency to step up and help us; and they didn’t hesitate,” he said. “The team out there — thousands of people — have really made this a special mission. As people have eluded to, ‘Perseverance’ has become a pretty good name for this mission.”

Launch Director Omar Baez of NASA’s Launch Services Program beamed with pride following his team’s flawless effort.

“Fantastic, honored, proud, ecstatic — those are the kind of words I can think of right now,” Baez said. “We hit right at the beginning of the window, and the vehicle performed perfectly. It’s just a proud moment, and I’m glad our program provided what was needed to get this on the way.”

ULA President and CEO Tory Bruno said before the launch that the rocket would leap off of the pad. On a calm, clear, and beautiful Florida day, that’s exactly what happened.

“We ignited, the Atlas performed nominally throughout the mission, and we ended with just an extraordinarily accurate orbital insertion,” Bruno said.

About the size of a car with dimensions similar to the Curiosity rover, Perseverance carries seven different scientific instruments. The rover’s astrobiology mission, developed under NASA’s Mars Exploration Program, will search for signs of past microbial life. It will characterize the planet’s climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.

The mission marks the first time in history that samples will be collected to bring back to Earth from another planet. Another first: Ingenuity, a twin-rotor, solar-powered helicopter attached to the belly of the rover, will become the first aircraft to fly on another world.

Perseverance will spend at least one Martian year, or approximately two Earth years, exploring the landing site region on the Red Planet. Though the mission has a long way to go, Thursday’s launch sent it off to a terrific start.

“I loved it,” said NASA Associate Administrator Thomas Zurbuchen. “It’s like punching a hole in the sky.”

Today’s the Day: Perseverance Being Prepped for Liftoff!

Good morning, and welcome to today’s live blog coverage of NASA’s Mars 2020 Perseverance rover launch! It is a beautiful morning here at NASA’s Kennedy Space Center in Florida.

We are just over an hour away from today’s scheduled 7:50 a.m. EDT liftoff from Cape Canaveral Air Force Station’s Space Launch Complex 41. There is a two-hour launch window. Perseverance will blast off aboard a United Launch Alliance (ULA) Atlas V 541 rocket to embark on its seven-month journey to the Red Planet. NASA’s Launch Services Program, (LSP) based at Kennedy, is managing the launch.

Weather reports have been positive — the U.S. Air Force 45th Weather Squadron predicted an 80% chance of favorable weather conditions for the launch. An updated weather report is expected shortly.

This mission is the culmination of years of dedicated work by thousands of people, including teams from NASA’s Jet Propulsion Laboratory, where the spacecraft was designed and built; Kennedy, where it was assembled; ULA, Lockheed Martin, and scientists from around the world. In the U.S., flight hardware was built in 44 states, involving more than 550 cities, towns and communities.

Perseverance, which will reach Mars on Feb. 18, 2021, is carrying seven different scientific instruments. The rover’s astrobiology mission, developed under NASA’s Mars Exploration Program, will search for signs of past microbial life. Ingenuity, a twin-rotor, solar-powered helicopter attached to the belly of the rover, will become the first aircraft to fly on another world.

NASA Television and the agency’s website will provide live launch coverage starting at 7 a.m. Stay tuned as the mission eclipses multiple milestones — including stage separation, main engine cutoff, and spacecraft separation — or follow along right here at blogs.nasa.gov/Mars2020.

Bursts of Florida afternoon rain showers could not dampen the spirts of NASA leaders on the eve of a much-anticipated mission to Mars.

“I’m exceptionally excited about what we’re about to do because we’re going to launch Mars 2020 with the Perseverance robot,” NASA Administrator Jim Bridenstine said during Wednesday’s briefing at the agency’s Kennedy Space Center. “But there is so much more going on here. This is the first time in history where we’re going to Mars with an explicit mission to find life on another world — ancient life on Mars.”

The briefing was held outdoors near the Florida spaceport’s iconic countdown clock. A temporary structure installed on the Press Site lawn shielded participants and limited media from the typical Sunshine State summer downpour.

The Mars 2020 Perseverance rover is scheduled to lift off aboard a United Launch Alliance Atlas V 541 rocket on Thursday, July 30, from Cape Canaveral Air Force Station’s Space Launch Complex 41 in Florida. The two-hour window opens at 7:50 a.m. EDT. NASA’s Launch Services Program, based at Kennedy, is managing the launch.

Despite dealing with significant challenges associated with COVID-19, Kennedy (and its surrounding area) is hosting the second major launch in two months. SpaceX’s Demo-2 mission, carrying NASA astronauts Douglas Hurley and Robert Behnken to the International Space Station, lifted off from Launch Complex 39A on May 30.

“When we started 2020, we knew we were going to have a big year at the spaceport,” Kennedy Deputy Director Janet Petro said. “And I think the events and the milestones of the next couple days are really going to demonstrate that.”

Developed under NASA’s Mars Exploration Program, the rover will search for signs of past microbial life. Perseverance will reach Mars on Feb. 18, 2021, touching down on the surface of Jezero Crater.

Attached to the belly of the rover and weighing less than four pounds is NASA’s Mars Helicopter, Ingenuity. The twin-rotor, solar-powered helicopter will become the first aircraft to fly on another world.

“Ingenuity is going to transform how we think about exploring worlds in the future,” Bridenstine said.

The rover will collect and store a set of rock and soil samples that could be returned to Earth by future Mars sample return missions. It also will test new technologies to benefit future robotic and human exploration of Mars.

“In 2026, we’re going to launch a mission from Earth to Mars to go pick up those samples and bring them back to Earth,” Bridenstine said. “For the first time in history, we’re doing a Mars sample return mission.”

NASA Television and the agency’s website will provide live launch coverage tomorrow morning, starting at 7. Stay tuned as the mission eclipses multiple milestones — including stage separation, main engine cutoff, and spacecraft separation — or follow along at blogs.nasa.gov/Mars2020. NASA will broadcast a post-launch news conference, beginning at 11:30 a.m.

Weather Outlook Remains Positive for Tomorrow Morning’s Liftoff

With two days to go until NASA’s Mars 2020 Perseverance rover blasts off on its seven-month journey to the Red Planet, everything is proceeding as planned.

On Tuesday, July 28, the rover made the one-third-mile trek from United Launch Alliance’s (ULA) Vertical Integration Facility to Cape Canaveral Air Force Station’s Space Launch Complex 41 in Florida. Now positioned at the pad, Perseverance is scheduled to launch aboard a United Launch Alliance Atlas V 541 rocket on Thursday, July 30. The two-hour window opens at 7:50 a.m. EDT. NASA’s Launch Services Program, (LSP) based at Kennedy, is managing the launch.

Weather reports are positive. The U.S. Air Force 45th Weather Squadron is predicting an 80% chance of favorable weather conditions for the launch. The primary weather concerns are cumulus and thick clouds.

Several obstacles — including navigating a worldwide pandemic — have been overcome to keep the mission on schedule.

“COVID has placed a heck of a burden on us to get through this,” Launch Director Omar Baez, LSP, said during Tuesday’s NASA Edge Rollout show. “So it lives up to its name, Perseverance, and we’re living it every day.”

“It has been quite the learning experience for the whole program — and the agency,” Baez continued. “But now, we’re really excited.”

Also Tuesday, NASA’s Kennedy Space Center hosted a pair of live shows highlighting the importance and impact of Perseverance’s mission: a Mars Sample Return briefing and a Mission Technology and Humans to Mars briefing. The rover will collect and store a set of rock and soil samples that could be returned to Earth by future Mars sample return missions.

“We’re looking to accomplish one of the most complex things humanity has ever attempted,” Mars Sample Return Program Director Jeff Gramling said. “With the launch of Perseverance will be the first step in a mission to bring back samples from another planet.”

Developed under NASA’s Mars Exploration Program, the rover will search for signs of past microbial life and help scientists better understand the geology and climate of Mars. Perseverance will reach Mars on Feb. 18, 2021, touching down on the surface of Jezero Crater. Lessons learned from the mission will pave the way for human exploration of the Red Planet.

NASA’s Mars Perseverance rover is now attached to the rocket that will carry it on its seven-month journey to the Red Planet for the agency’s Mars 2020 mission.

On Tuesday, July 7, a team of engineers fastened the payload fairing, containing the rover and remainder of the spacecraft – the aeroshell backshell, descent stage and cruise stage – to a United Launch Alliance (ULA) Atlas V booster inside the Vertical Integration Facility (VIF) at Cape Canaveral Air Force Station’s Space Launch Complex 41 in Florida. The rocket’s upper stage and spacecraft will remain attached until about 55 minutes after launch, after which the two will separate, sending Perseverance on its solo journey to Mars.

With the spacecraft and booster now connected, final testing of the two – separately and together as one unit – can begin. Once those tests are complete, the rocket will leave the VIF on the morning of July 28 for its journey to the launch pad – just 1,800 feet away.

NASA and United Launch Alliance are now targeting Thurs., July 30, at 7:50 a.m. ET, with a two-hour window, for launch of the Mars 2020 mission. The team identified the cause of the issue with the liquid oxygen sensor line found during Wet Dress Rehearsal (WDR). A small leak was located in the weld of the line, which has been repaired and tested.

The rover, carrying seven different scientific instruments, is slated to arrive at the Red Planet on Feb. 18, 2021, regardless of what day it lifts off during the launch period. During its time on Mars, Perseverance will search for signs of past microbial life and collect rock and soil samples of the Martian surface for future return to Earth.

The mission, managed by NASA’s Science Mission Directorate and the Jet Propulsion Lab (JPL), will provide key insight into some of the challenges associated with future human exploration of Mars. NASA’s Launch Services Program based at Kennedy Space Center is managing the launch.
