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 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.

How to get more space in your Google storage

For large numbers of us, Google stockpiling is the advanced hard drive. It’s where our most significant contemplations, archives, and recollections live. In any case, much the same as with a customary hard drive, the space isn’t endless, and running out of room can be a genuine issue.

Of course, Google gives you 15GB of space to use for everything related with your record. (In the event that you have a paid G Suite account, your cutoff’s conceivable higher.) That incorporates content associated with Gmail, Google Drive, and all Google Photos saved after June first. Obviously, information includes quick.

You can check your present stockpiling status by visiting this page, and when it’s all said and done, you can buy more space there, as well, for just $2 per month for an extra 100GB. Be that as it may, dishing out more cash probably won’t be essential. A speedy round of antiquated housekeeping could be sufficient to clean up your virtual webs and give yourself plentiful space to develop. Here’s the means by which to do it.

Delete Drive debris

Google Drive is a common place for space-sucking files to build up and wear down your quota, but tidying things up doesn’t take long.

  • Open this link, which will show you a list of all of your Drive files sorted by size with the largest items at the top
  • Look through the heftiest offenders and delete anything you no longer need
  • Click the gear-shaped icon in Drive’s upper-right corner, and select “Settings,” followed by “Manage Apps”
  • For any apps that have a note about hidden data, click the gray “Options” box to the right, and select “Delete hidden app data”

Apps associated with your Google Drive storage can sometimes have hidden data, but all it takes is a couple of clicks to remove it.

Free up Photos storage

Unless you currently have a Pixel phone (in which case, you will, for now, keep the unlimited “high quality” option), as of June 1st, 2021, every photo and video backed up to Google Photos is going to count against your Google storage. If you’ve been saving photos at their original sizes, you can free up tons of space by converting them to Google’s “high-quality” option, which compresses images down to 16MP and videos to 1080p (a change that’s unlikely to be noticeable for most people and purposes).

  • Go to the Photos settings page, and select “High quality (free unlimited storage)”
  • When you make that selection, you’ll be asked whether you want to switch to the “high quality” format and compress your existing photos. If there are any photos you don’t want to compress, click on the “Learn how to keep original files” link for instructions on saving those photos to your device.

 

Say goodbye to Gmail junk

Emails don’t take up a ton of space, but you know what does? Attachments. Odds are, you’ve got plenty of old attachments sitting in your Gmail account that you don’t really need.

Here’s how to address that:

  • Go to the Gmail website and type “has:attachment larger:10M” into the search box at the top
  • Identify any messages with disposable attachments and delete them. (There’s no great way to get rid of an attachment without also deleting the associated email, unfortunately, but you can always forward a message back to yourself and manually remove the attachment before axing the original.)
  • Open your Spam folder, and click the link to “Delete all spam messages now”
  • Open your Trash folder, and select “Empty Trash now” to send everything away for good

Feeling lighter is liberating, isn’t it?

NFL insider figures Eagles will exchange Carson Wentz this week | What it implies for Jets’ Sam Darnold

Day 42 of the endless Carson Wentz exchange gossipy tidbits adventure brings us Les Bowen sharing what he’s finding out about the Philadelphia Eagles’ quarterback circumstance. Here’s the understanding he shared subsequent to talking with an alliance source:

Reports show that the Chicago Bears have pushed more enthusiastically to exchange for Wentz than the Indianapolis Colts have. However, in the event that Wentz would not like to go to the Windy City, which is reasonable from a stance of Indy being more best, at that point it doesn’t appear as though he will wind up visiting Lou Malnati’s at any point in the near future. Indeed, the Eagles can exchange him without wanting to … in any case, are the Bears in any event, presenting a genuine offer on the off chance that they realize Wentz would not like to play in Chicago?

Thus if the Eagles are really determined to exchanging Wentz, as still seems, by all accounts, to be the situation, they’ll most likely need to take what the Colts are advertising. Indy’s offered was recently answered to be two second-round picks, however I’ve heard things that cause me to accept the proposition may really be even less rewarding than that. The Colts obviously just need to gain Wentz at a value that coordinates their solace level.

Getting to that last line of what Bowen initially tweeted, it shouldn’t come as a stun that drafting a quarterback will be on the table for an association that named itself a “QB industrial facility.” If the Eagles were able to draft Jalen Hurts with a second-round pick a year ago when they thought they really had an establishment quarterback, is there any valid reason why they wouldn’t draft one when they couldn’t say whether they have such an answer? Damages has potential, perhaps, yet he’s a long way from a slam dunk.

There’s a contention the Eagles should brave it with Hurts for a year and see what he has. On the off chance that he’s awful, the group can zero in on drafting a quarterback one year from now. 2021 is turning out to be a lost season in any case.

Simply trusting Hurts can be the appropriate response is certainly not a genuine system, however. On the off chance that you don’t have an establishment quarterback, you need to take the necessary steps to get one.

The issue is, it’s difficult to have the confidence in this system distinguishing such an ability and effectively working around him in the long haul. The Eagles plainly neglected to do as much with Wentz.

ESA said it anticipates the “parastronaut attainability project” to “open a chance of trip for at least one people” while likewise bringing “advancements and different advantages to the security and proficiency of future groups.”

Recruiting ESA’s 2021-2022 astronaut class

Since its beginning, ESA has enlisted new space explorers only multiple times. The primary enlistment crusade occurred somewhere in the range of 1978 and 1979 and the latest somewhere in the range of 2008 and 2009.

Applications for the main period of the 2021-2022 ESA space traveler determination interaction will be acknowledged from March 1 to May 28. Candidates will be needed, at least, to be a resident of an ESA part state or partner part state, hold a Master’s certificate in regular sciences, medication, designing or math, have in any event three years proficient experience, and communicate in English smoothly.

Notwithstanding the base prerequisites, the organization depicts an ideal up-and-comer as a person that can function admirably inside a multicultural group, invest significant length of energy away from loved ones, go through incredible actual preparing, and stay quiet under tension.

The new class of ESA space travelers will be drafted into the organization’s space explorer corps at perhaps the most momentous occasions in its set of experiences. Notwithstanding proceeding to send space travelers to work and live on board the International Space Station, ESA’s commitments to NASA’s Artemis program and lunar Gateway space station has empowered the organization to tie down seats for the principal European space travelers to go past low Earth circle, situates that could be loaded up with space explorers enlisted over the course of the following two years.

The 2021-2022 ESA space traveler determination interaction will comprise of six phases following introductory choices. The interaction is relied upon to start May 28 and close with the declaration of the most current ESA space traveler class in the second 50% of 2022.

Need to put resources into Nothing? Carl Pei opens speculation freedom to local area

Carl Pei, co-founder of OnePlus, knows a thing or two about communities. At the Chinese smartphone maker, Pei fielded product and feature ideas from fans and held frequent gatherings to hear their feedback. At his new venture, Nothing, Pei is going a step further.

The London-headquartered firm said on Tuesday it will allow its community to invest $1.5 million in the company through a community equity round early next month. One community member will be elected to Nothing’s board of directors to always keep the firm in “check” and remind it of “what users want,” said Pei.

The startup, which recently raised a $15 million Series A round from Alphabet’s GV, said it will raise money from the community at the same valuation as implied in the Series A round. (The startup has raised an additional $7 million from high-profile executives including Kunal Shah of Cred, Tony Fadell, principal at Future Shape and inventor of the iPod, well-known YouTuber Casey Neistat, Kevin Lin, co-founder of Twitch, and Steve Huffman, chief executive of Reddit.)

“We want our community to be part of our journey from the very start and play an active role in it,” said Pei, who serves as the chief executive of Nothing. Pre-registrations to the financing option will open on February 16 at 10 a.m. GMT, and the campaign will go live on March 2 at 10 a.m. GMT.

Pei has yet to share what products he wants to tackle at his new venture. So far he has said the startup plans to develop a pair of wireless headphones and smart and connected consumer electronics devices.

Science News18 asked him why he couldn’t do all of this at OnePlus. “When you want to build something new and different, the best way is to start off on a clean sheet and with a change of environment,” he said.

This week, 9to5Google reported that Nothing had acquired some trademarks from Android creator Andy Rubin’s now-defunct Essential.
