========================================================================== Humanity's most sophisticated rover launched with the Ingenuity Mars
Helicopter at 7:50 a.m. EDT (4:50 a.m. PDT) Friday 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 viaNASA's Deep Space Networkat 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.
==========================================================================
The 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 exploration.
"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." The 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.
An 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.
==========================================================================
Also 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 instruments.
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 Mars.
"Perseverance 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.
"There 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.
