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.

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.

“I just couldn’t be happier to be here today and have this amazing mission on top of a rocket and ready to go,” said Thomas Zurbuchen, associate administrator, NASA’s Science Mission Directorate. “From this launch readiness review … all the issues are addressed and we are in fact ready now; we’re just counting down and really celebrating with the team.”

Perseverance will collect samples from the Red Planet that could be returned to Earth on a future mission. These samples would provide unprecedented information about the Martian climate and weather.

“We’re doing transformative science; really for the first time, we’re looking for signs of life on another planet,” said Matt Wallace, deputy project manager, NASA’s Jet Propulsion Laboratory.

The mission has involved thousands of people in a cross-agency effort that included scientists from around the world. In the U.S., flight hardware was built in 44 states, involving more than 550 cities, towns and communities.

“So no matter where you are in this country, you don’t have to go very far probably to find somebody who has been a part of this mission,” Wallace said. “It’s a tremendous team effort.”

Multiple events will be broadcast Tuesday on NASA Television and the agency’s website: NASA Edge Rollout show, from 10 to 11 a.m.; Mars 2020 Mars Sample Return briefing, from 2 to 3 p.m.; and Mars 2020 Mission Tech and Humans to Mars briefing, from 4 to 5 p.m.

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.
