Summary of functions and missions of NASA’s “Perseverance” spacecraft with Mars landing in countdown

The Mars rover ” Perseverance “, which NASA successfully launched in July 2020, was launched before 16:00 on February 18, 2021 (19th Japan time ) in eastern US time. We will arrive on Mars before 6 o’clock). Therefore, the journal “IEEE Spectrum”, which specializes in electrical engineering technology, summarized the differences between perseverance and conventional spacecraft and the mission to be carried out on Mars. You Need To Everything Know About NASA’S Perseverance Rover Landing On Mars – IEEE Spectrum Https://Spectrum.Ieee.Org/automaton/aerospace/robotic-exploration/nasa-perseverance-rover-landing-on-mars-overview parser via lance , Mars exploration mission “that NASA has implemented Mars 2020 as part of the” Mars helicopter ” Ingenuity (Ingenuity) ” along with the Mars exploration Rovers, which was launched in July 2020. NASA’s site ” Eyes on the Solar System ” that displays the major celestial bodies of the solar system and space exploration missions in real time

NASA Perseverance landing today: When & how to watch the Mars rover

If you access, you can see that the Mars 2020 rocket equipped with Perseverance is approaching 430,000 km from Mars at the time of writing the article.

IEEE Spectrum explained the perseverance that is about to enter Mars, focusing on the following seven points.

1.Purpose and function

of perseverance NASA said about perseverance, “The ultimate goal of this exploration rover is to investigate a specific point in detail to find traces of life that existed in the past. To achieve this, Perseverance will identify and collect materially valuable rock cores and soil samples for future missions to bring them back to Earth. Perseverance will also take place in the future. It also tests the technology needed for Mars exploration. ” Perseverance

is a camera capable of panoramic and stereoscopic photography, ” Mastcam-Z “, ” SuperCam ” equipped with remote sensing equipment such as a laser and a spectrometer that evaporates rocks, and a sensor specializing in the discovery of organic molecules. “group SHERLOC “, “measurement tools equipped with microscope PIXL ” underground 10m water or ice can be detected by the radar ” RIMFAX “, temperature, pressure, humidity, wind speed, wind direction and atmospheric composition dust etc. ” MEDA ” for observing, ” MOXIE ” for testing the technology to generate oxygen from carbon dioxide, ” Sample Caching System ” for long-term storage of collected samplesIt is said that they will make full use of these to investigate Mars and prepare for future missions.

2. Differences between Perseverance and conventional Mars spacecraft

NASA launched the Mars spacecraft ” Curiosity ” in 2011, from the start of the Mars mission in 2012 to the time of article creation. It continues to operate.

Curiosity (left) and Perseverance (right) are similar in terms of overall design and the use of radioactive isotope-based atomic batteries as the power source, but they are significantly more functional and durable. There is a difference.

According to the Caltech IEEE Spectrum, Perseverance is about the same size as Curiosity, but weighs nearly 100 kg. Most of this weight difference comes from the weight difference of the robot arm full of SHERLOC, PIXL, drilling drills, etc. mentioned above. In addition, Perseverance is equipped with a total of 23 cameras, five more than Curiosity, and is the first Mars probe to be equipped with a microphone for capturing the “sound of Mars.”

It also overcomes the problem of “wheel wear” that Curiosity had. Curiosity is equipped with aluminum wheels, but they wear faster than expected, resulting in unexpected holes and dents in the wheels.

On the other hand, the wheels of Perseverance (right) are 1mm thicker than the wheels of Curiosity (left), which improves resistance to wear while maintaining performance. ..

In addition, by strengthening the software, it has acquired higher autonomy than Curiosity, and it is also possible to find a driving route independently and move more efficiently than Curiosity. ..

3. Destination of Perseverance Perseverance

will land on a crater called Jezero on the Syrtis Major Planum on Mars . Jezero has a lake-like terrain as it means “lake” in Slavonic, and there is also a delta . From this, it is speculated that Jezero had liquid water for a long time, and if you are looking for traces of life on Mars, Jezero is considered to be the best choice.

4. Landing method of

perseverance When the descent unit containing the perseverance approaches the surface of Mars, the parachute first opens and decelerates. After that, a power descent is performed in which the landing stage injects propellant to decelerate, and then the “sky crane system” is adopted in which the perseverance is hung by a rope and lands on the ground surface. The aforementioned Curio City also landed on Mars in this way.

5. What is the Mars helicopter “Ingenuity”?

The bottom of the Perseverance is also equipped with a heat shielded ingenuity, which will be deployed after the successful landing of the Perseverance and will carry out five flights in 30 days. Ingenuity’s main purpose is to test flights on Mars, so unlike Perseverance, it is not used for scientific research, but there are various engineering aspects such as achieving autonomous flight for the first time in the atmosphere of Mars. It is expected to accomplish great things.

6. How to see the moment of perseverance landing?

NASA will broadcast live the appearance of Perseverance landing. The distribution will start on the following YouTube page from 14:15 on February 18th, Eastern Time.

7. What will happen when the landing is successful or unsuccessful?

Perseverance is scheduled to land on Mars at around 15:55 EST on February 18 (around 5:55 EST on 19th), but because the Earth and Mars are so far apart, they are far from Earth. It is not possible to know the success or failure of landing and its appearance in real time. Perseverance signals NASA’s Jet Propulsion Laboratory (JPL) at each stage of landing, from which you can see if the landing is successful.

The IEEE Spectrum says, “The most likely sign that something is going wrong is that no signal is being sent, but that negative information is not very well communicated and is simply overlooked. It’s possible that the problem isn’t so big just because it’s done. If something goes wrong, there will be a time lag of minutes, hours, or even days before it becomes known. ” Said.

If Perseverance successfully lands on Mars, Perseverance will send you a photo of Mars, but as mentioned above, it will take minutes to hours for the image to reach Earth from Mars. It is a prospect. Also, the photo immediately after landing will be taken with a Perseverance emergency camera, and the camera is likely to have a protective cover attached, so it’s not like a great sight. And that. IEEE Spectrum said, “The high-resolution photos sent by Curiosity were taken after the rover’s mast was unfolded, so it will be a while before Perseverance sends similar photos. “.

In addition, Perseverance has its own official Twitter account, so if you want to know the latest information, it seems good to follow it.

NASA Perseverance landing today: How to land on Mars [UPDATED with livestream]

It is one of the big day the plucky Mars 2020 rover Perseverance has been waiting for, with NASA preparing a nail-biting descent to the red planet today. If all goes to plan, it’ll be a successful end to a very long journey: Mars is currently 127 million miles away from Earth, with Perseverance blasting off to begin its trip on July 30, 2020.

Perseverance isn’t the first Mars rover, of course, but it’s definitely NASA’s most complex and adept. Its payload of seven scientific instruments and 19 cameras will give scientists unprecedented views both of the Martian surface, and underneath, as the rover attempts to help unlock the secrets of the planet’s origins. However arguably the most exciting part of the mission is designed to detached.

Perseverance will also take a helicopter, named Ingenuity, down to the surface. It’s designed to come away from the rover and then take to the skies, beaming down imagery of the Jezero crater in which NASA intends to land, and helping plan for future missions. If successful, it’ll be the first example of powered flight on another planet that humankind has achieved.

Though Perseverance is designed to run for some time on Mars, its legacy will be even longer-lasting. One of the mission goals is to collect samples from the surface and underneath it, package them up into special containers, and then leave them for a future Mars mission to collect. They’ll then be returned to Earth for analysis, though that’s not expected to take place until some time in the 2030s.

Before that, of course, the rover has to make it down in one piece. If all goes to plan, that’ll begin at around 3:48pm EST (12:48pm PST) today, February 18, 2021. According to the schedule, touchdown should take place at around 3:55pm EST.

How to land on Mars

Though the Martian atmosphere is thin, it will nonetheless provide a majority of the resistance to slow Perseverance down. Within about 80 seconds of entering the Martian atmosphere, temperatures outside the aeroshell are expected to reach 1300° Celsius.

About four minutes after encountering the atmosphere, the vehicle’s parachutes will deploy. Shortly after, the protective aeroshell will fall away, its job done. Then, when the vehicle descends to about 4km above the planet’s surface, it will activate its Terrain Navigation System. Up until this point, Perseverance’s trip will be very similar to that of the Curiosity rover, which underwent a similar “seven minutes of terror” during its successful landing in August 2012.
