NASA, ULA Launch Mars 2020 Perseverance Rover Mission to Red Planet

The agency’s Mars 2020 mission is on its way. It will land at Jezero Crater in about seven months, on Feb. 18, 2021.

NASA’s Mars
2020 Perseverance rover mission is on its way to the
Red Planet to search for signs of ancient life and collect samples to send back
to Earth.

Humanity’s most sophisticated rover launched with the Ingenuity Mars Helicopter at 7:50 a.m. EDT (4:50 a.m. PDT)
Thursday on a United Launch Alliance (ULA) Atlas V rocket from Space Launch
Complex 41 at Cape Canaveral Air Force Station in Florida.

“With the launch of Perseverance, we begin
another historic mission of exploration,” said NASA Administrator Jim
Bridenstine. “This amazing explorer’s journey has already required the
very best from all of us to get it to launch through these challenging times.
Now we can look forward to its incredible science and to bringing samples of
Mars home even as we advance human missions to the Red Planet. As a mission, as
an agency, and as a country, we will persevere.”

The ULA Atlas V’s Centaur upper stage initially placed the Mars 2020 spacecraft into a parking orbit around Earth. The engine fired for a second time and the spacecraft separated from the Centaur as expected. Navigation data indicate the spacecraft is perfectly on course to Mars.

Mars 2020 sent its first signal to ground controllers via NASA’s Deep Space Network at 9:15 a.m. EDT (6:15 a.m. PDT). However, telemetry (more detailed spacecraft data) had not yet been acquired at that point. Around 11:30 a.m. EDT (8:30 a.m. PDT), a signal with telemetry was received from Mars 2020 by NASA ground stations. 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. All temperatures are now nominal and the spacecraft is out of Earth’s shadow.

When a spacecraft enters safe mode, all but essential systems are turned off until it receives new commands from mission control. 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. 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.

Perseverance rover’s astrobiology mission is to seek out
signs of past microscopic life on Mars, explore the diverse geology of its landing
site, Jezero Crater, and demonstrate key
technologies that will help us prepare for future robotic and human

“Jezero Crater is the perfect place to
search for signs of ancient life,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission
Directorate at the agency’s headquarters in Washington. “Perseverance is
going to make discoveries that cause us to rethink our questions about what
Mars was like and how we understand it today. As our instruments investigate
rocks along an ancient lake bottom and select samples to return to Earth, we
may very well be reaching back in time to get the information scientists
need to say that life has existed elsewhere in the universe.”

Martian rock and dust Perseverance’s Sample Caching System collects could answer
fundamental questions about the potential for life to exist beyond Earth. Two future
missions currently under consideration by NASA, in collaboration with
ESA (European Space Agency), will work together to get the samples to an orbiter for
return to Earth. When they arrive on Earth, the Mars samples will undergo
in-depth analysis by scientists
around the world using equipment far too large to send to the Red Planet.

To get ready for the launch of the Mars 2020 Perseverance rover, NASA invited the public to join a global, collective #CountdownToMars project.

Eye to a Martian Tomorrow

While most of
Perseverance’s seven instruments are geared toward learning more about the
planet’s geology and astrobiology, the MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment)
instrument’s job is focused on missions yet to come. Designed to demonstrate
that converting Martian carbon dioxide into oxygen is possible, it could lead
to future versions of MOXIE technology that become staples on Mars missions,
providing oxygen for rocket fuel and breathable air.

future-leaning is the Ingenuity Mars Helicopter, which will remain attached to
the belly of Perseverance for the flight to Mars and the first 60 or so days on
the surface. A technology demonstrator, Ingenuity’s goal is a pure flight test – it carries no science

Over 30 sols (31 Earth days), the helicopter will attempt
up to five powered, controlled flights. The data acquired during these flight
tests will help the next generation of Mars helicopters provide an aerial dimension to Mars explorations – potentially scouting for
rovers and human crews, transporting small payloads, or
investigating difficult-to-reach destinations.

The rover’s technologies for entry, descent,
and landing also will provide information to advance future human missions to

is the most capable rover in history because it is standing on the shoulders of
our pioneers Sojourner, Spirit, Opportunity, and Curiosity,” said Michael
Watkins, director of NASA’s Jet Propulsion Laboratory in Southern
California. “In the same way, the descendants of Ingenuity and MOXIE will
become valuable tools for future explorers to the Red Planet and beyond.”

About seven
cold, dark, unforgiving months of interplanetary space travel lay ahead for the
mission – a fact never far from the mind of Mars 2020 project team.

is still a lot of road between us and Mars,” said John McNamee, Mars 2020
project manager at JPL. “About 290 million miles of them. But if there was
ever a team that could make it happen, it is this one. We are going to Jezero
Crater. We will see you there Feb. 18, 2021.”

The Mars 2020 Perseverance mission is part of America’s larger Moon to
Mars exploration approach that includes missions to the Moon as a way to
prepare for human exploration of the Red Planet. Charged with sending the first
woman and next man to the Moon by 2024, NASA will establish a sustained human
presence on and around the Moon by 2028 through NASA’s Artemis program.

JPL, which is managed for NASA
by Caltech in Pasadena, California, built and will manage operations of the
Mars Perseverance rover. NASA’s Launch Services Program, based at the agency’s
Kennedy Space Center in Florida, is responsible for launch management, and ULA
provided the Atlas V rocket.
