This is part of the story Welcome to mars, Our series explores the red planet.

It’s been july An exceptionally busy month for Martian robot explorers. UAE’s Hope Probe On 19 July, left Earth for the Red Planet and China’s Tianwen-1, which had a trio of robots, Shortly after. Now, it’s NASA’s turn. On Thursday, it Defectively launched two robot explorers For Red Planet: A next generation rover, known as the Perseverance, And a helicopter, known as Ingenuity.

Ingenuity is a technical demonstration aimed at the first vehicle to achieve powered-flight on another planet. Persistence has a big, folder mission – on it can change our understanding forever. It will hunt for signs of past life on the red planet.

The dry, dusty Mars we know today was very different from the deep past. Humanity’s latest rover is building a beeline for an area of ​​Mars that was once home to the lake, an ideal place to look for signs of ancient microbes.

Since Sojourner in 1997, NASA has sent a succession of increasingly sophisticated wheel explorers to Mars. Perseverance is the latest and greatest and in July 2020, it launched on an epic journey into space.

Firmness Will do much more than amazing pictures of Mars. These are some important mission objectives:

  • Watch for signs of ancient microbial life.
  • Collect samples of Martian rock and dust to return to Earth later.
  • Deliver an experimental helicopter.
  • Study the climate and geology of Mars.
  • Demonstration of technology for future Mars missions.

The mission is planned to last at least one Mars year, which works on Earth for about 687 days (Mars takes longer to get around the Sun). However, NASA has a good track record with expanding its robot Mars missions. We can see long-lived opportunities and curiosity rovers as role models for this.

Hello mars

NASA conducted extensive tests of the parachute system that would reduce the persistence on Mars.

Mars arrival of the rover is scheduled for February 18, 2021. The landing process will include some of the most difficult minutes of the entire mission.

A new approach will be strongly tried that NASA hopes will deliver it as close to its target landing site as possible. NASA calls it “range trigger” technology and is about deploying parachutes at exactly the right time.

“If the spacecraft was going to meet the landing target, the parachute would have already been deployed,” NASA said. “If it was going to fall short of the target, the spacecraft would deploy later, as the spacecraft flew a little closer to its target.”

Earth observers can await an unprecedented view of the entry, descent and landing process. The mission is equipped with cameras and a microphone to capture all of the excitement and tension as NASA attempts to land strongly on the surface of Mars.

Jagero crater

Jagero crater Located just north of the equator of Mars and was once home to the river delta. That history of water makes it a prime place to look for signs of past microbial life. On Wheels seems like the perfect landing site for a science lab.

NASA’s Thomas Burbchen said it was announced in 2018, “The landing site at the Jagero crater provides geologically rich terrain, which is 3.6 billion years old.”

Vital data

The car’s Persistence Rover looks similar to its predecessor, the Curiosity, but still represents quite a bit of technological advancement after the Curiosity was designed. These numbers are:

Length: 10 ft (3 m)
Weight: 2,260 lb (1,025 kg)
Wheels: Six aluminum wheels with titanium spokes
top speed: Just under 0.1-mph (152 mph)

Science tools

The Persistence Rover is stocked with equipment that it will use to examine the Jazero crater on Mars.

Fortitude is loaded with seven instruments chosen to help achieve the objectives of its mission. You can get the full bandan from NASA, but here are some key points:

Mastcam-Z: The camera system mounted on the rover’s mast is equivalent to a head-on eye. According to NASA, its main work is to “take high-definition video, panoramic colors, and 3D images of the Martian surface and features in environments with zoom lenses to enhance distant targets.” The Mastcam will be our main viewing window on the Zzero crater.

Moxie: The Mars Oxygen In-situ Resource Utilization experiment is one of the ways that are strongly helping humans prepare to go to Mars. This device is designed to produce oxygen from the carbon-dioxide atmosphere. This capability will be necessary to help future human explorers breathe, but it will also help us make propellants for rockets on site. This is a necessary step to bring our Mars astronauts back to Earth after their mission.

SuperCam: When you put a camera, laser, and spectrometer together, you get a Supercam, a device that will help in the search for organic compounds, an important part of the search for signs of past microorganism life. “It can identify the chemical and mineral makeup of a target as small as a pencil point at a distance of more than 20 feet (7 m),” NASA said.

Sherloc: “Scanning Habitable Environment” with Raman & Lumination for Organics & Chemicals, affectionately known as the instrument, will search for signs of life on the red planet. The device and its companion camera (nicknamed Watson) are capable of taking microscopic images of Mars and analyzing them. Equipped with a laser it can fire on the surface, capable of measuring chemicals present in soil and rock using a technique called Sherlock spectroscopy.

Helicopter on board

The NASA Mars helicopter team attaches a piece to the flight model in early 2019.

“Let’s send a helicopter to Mars” may sound a bit far-fetched, but NASA is doing it anyway. Simplicity, A small helicopter designed to operate in challenging conditions on the Red Planet, is all tucked into the rover’s belly where it will ride the journey.

Ingenuity is a high-risk, high-reward technology demonstration. It will hang under the rover for a few months until NASA finds a suitable place to deploy it. Perseverance will leave it on the surface of Mars and then move away.

The helicopter will make its first attempt at a flight operated on another planet. NASA hopes that Ingenuity climbs and becomes a model for a new way to investigate other worlds.

Connecting with your siblings

NASA currently operates two machines on the surface of Mars, the Stable Insight Lander and the Mars Rover Curiosity. Insight is located in an area known as ileum planitia, which is a large plain area. Curiosity hovers around the Gayle crater, a huge moat with a huge mountain inside it. Strongly a very different part of the planet will exit as it continues the legacy of NASA’s discovery of Mars.

The last time we had two working rovers on Mars was in 2018. Opportunity Rover lost contact with home Due to the impact of a global dust storm. There will not be the same issues of persistence as opportunity. Like curiosity, it uses a nuclear power source that does not require sunlight to keep it running.

‘Explore as one’

This plate has the names of approximately 11 million people and a coded message.

NASA / JPL-Caltech

Perseverance will go a long way from Earth, but it will carry poignant memories of its home planet. Over 10.9 million people signed up to travel with their namesake rover Send your name to Mars public outreach program through NASA. The names are etched on small silicon chips that NASA has installed on a rover on an aluminum plate under a protective shield.

The plate also has a depiction of the Earth, our Sun and Mars. Hidden in the sun’s rays The message is “written in morse code, explore as one”.

a Separate aluminum plates pay tribute to health care workers And his efforts to aid humanity during the coronovirus epidemic. The plate depicts a snake wrapped around a rod with the earth at the top.

These names and messages remind that NASA’s robot explorers never actually travel alone. Perseverance is the culmination of years of NASA efforts, but it is also a messenger for humanity, expanding our curiosity and sense of wonder and a little bit of Earth on Mars.
