With three days to go until liftoff of NASA’s Mars 2020 Perseverance rover, everything is on track for Thursday’s planned launch to the Red Planet.

“The launch readiness review is complete and we are indeed ‘go’ for launch,” NASA Administrator Jim Bridenstine said during Monday’s news conference at the agency’s Kennedy Space Center in Florida. “This has been an amazing team effort.”

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

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

The historic mission has remained on track, despite unprecedented challenges from a worldwide pandemic.

“We are in extraordinary times right now with the coronavirus pandemic, and yet we have, in fact, persevered,” Bridenstine said. “And we have protected this mission because it is so important.”

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.

From noon to 1 p.m. Wednesday, there will be a briefing featuring Bridenstine, NASA Deputy Administrator Jim Morhard, Kennedy Deputy Director Janet Petro, and astronaut Zena Cardman.

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.

Activities have continued to ramp up with the attachment of the four solid rocket boosters (SRBs) one-by-one to the sides of the Atlas V 541 rocket, followed by the Centaur upper stage. The Centaur can control its orientation precisely, while providing up to 22,300 pounds of thrust. The spacecraft will be mated to the Atlas V rocket on June 22.

The assembly, test and launch operations team from NASA’s Jet Propulsion Laboratory and United Launch Alliance (ULA) engineers have hit multiple key milestones in the past two months, keeping Perseverance on target for its launch to the Red Planet in mid-July. These include attaching the aeroshell backshell and attaching the rover to its rocket-powered descent stage, rotating and spinning the descent stage on two separate measuring fixtures to pinpoint its center of gravity, and attaching NASA’s Mars Helicopter, recently named Ingenuity, to the belly of the rover.

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

The rover, carrying seven different scientific instruments, will lift off from Cape Canaveral Air Force Station. Launch is scheduled for Monday, July 20, at 9:15 a.m. ET, with a two-hour window. NASA’s Launch Services Program based at Kennedy is managing the launch. For more information on Perseverance and its mission, visit the mission website.

Testing on NASA’s Mars Perseverance rover at Kennedy Space Center closed out April on an extremely high note.

The latest activities at the Florida spaceport included attaching the aeroshell backshell on April 29 and attaching the rover to its rocket-powered descent stage on April 23 inside the Payload Hazardous Servicing Facility. The rover and descent stage were the first spacecraft components to come together for launch — and they will be the last to separate when the spacecraft reaches Mars on Feb. 18, 2021.

The backshell carries the parachute and several components that will be used during later stages of entry, descent and landing. The aeroshell will encapsulate and protect Perseverance and its descent stage during their deep space journey to Mars and during descent through the Martian atmosphere, which generates intense heat.

April saw other key rover milestones reached at Kennedy. On April 14, the

descent stage — fully loaded with 884 pounds of fuel (a hydrazine monopropellant) — was rotated and spun on two separate measuring fixtures to pinpoint its center of gravity.  This will help ensure the descent stage remains stable while guiding Perseverance to a safe landing.

On April 6, NASA’s Mars Helicopter, recently named Ingenuity, was attached to the belly of the rover. Weighing less than four pounds, the twin-rotor, solar-powered helicopter will be released to perform the first in a series of flight tests that will take place during 30 Martian days (a day on Mars is about 40 minutes longer than a day on Earth). Ingenuity will become the first aircraft to fly on another world.

Thanks to the enduring efforts of NASA and United Launch Alliance (ULA) engineers, Perseverance remains on track for its targeted launch period, which opens in just six weeks. The rover will liftoff aboard a ULA Atlas V 541 rocket from Cape Canaveral Air Force Station. NASA’s Launch Services Program based at Kennedy is managing the launch.

After the rover enters the thin Martian atmosphere, the descent stage will complete the slowing of Perseverance to less than two miles per hour. At about 65 feet over the Martian surface, the descent stage — utilizing a tether of nylon cords — will lower Perseverance to the surface of Jezero Crater. The rover will then sever the cords and the descent stage will fly away.

About the size of a car with dimensions similar to the Curiosity rover, Perseverance will carry seven different scientific instruments. Developed under NASA’s Mars Exploration Program, the rover’s astrobiology mission 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 twin-rotor, solar-powered helicopter weighs less than 4 pounds; the total length of its rotors is about 4 feet, tip to tip. Its main purpose is a technology demonstration. After Perseverance safely lands on Mars, the helicopter will be released to perform the first in a series of flight tests that will take place during 30 Martian days (a day on Mars is about 40 minutes longer than a day on Earth).

For history’s first flight experimental flight test in the thin Martian atmosphere (less than 1% the density of Earth’s), the helicopter is tasked with hovering in the air a few feet off the ground for 20 to 30 seconds before landing. It is designed to fly on its own, without human control, using minimal commands from Earth sent in advance.

With the helicopter safely tucked away and covered by a shield to protect it during descent and landing, Perseverance will touch down on the Red Planet on Feb. 18, 2021. Liftoff aboard a United Launch Alliance Atlas V 541 rocket is targeted between July 17 and Aug. 5 from Cape Canaveral Air Force Station.

NASA’s Launch Services Program based at Kennedy is managing the launch. For more in-depth information, visit the mission’s website.
