The Perseverance rover just encountered a problem on Mars

Published

on

On Mars, NASA’s Perseverance rover continues to search for traces of ancient life in Jezero crater. Currently, the rover is in the midst of taking samples for analysis on Earth. But recently, Perseverance encountered a problem with its direct debit system, a problem that could delay further operations.

According to reports, the rover had just taken its sixth sample last month. But the robot then detected that debris from Martian rocks was obstructing its robotic arm which therefore cannot proceed to the storage of the sample.

Fortunately, no permanent damage was caused by the presence of the debris. According to Louise Jandura, chief engineer in charge of sample collection at NASA’s Jet Propulsion Laboratory, the rover behaved as expected. He paused the procedure and contacted Earth for instructions.

Debris to be removed

According to NASA scientists, Perseverance sensors began registering resistance earlier than expected due to the additional debris. Indeed, the rover’s system was designed to take into account the presence of debris during operations, as Jandura explains.

Jandura said it was the first time they had to carry out debris removal. They want to take the time necessary to ensure that the stones are removed in a controlled manner.

The difficulty of the task

It won’t be easy for the engineers to remove the debris stuck inside the Perseverance system. The task will be all the more difficult as the data transmissions are delayed because of the distance between the two planets, but also because of the times when the Earth and Mars are not synchronized.

Jandura explains that this isn’t the first challenge they’ve encountered on Mars, it’s just the latest. When the engineering problem is hundreds of millions of miles away, she says, you have to take your time and be thorough.

So let’s hope that Perseverance will succeed in getting rid of the debris that is stuck in its system and that it can continue its mission of searching for traces of an old life.

“A little closer to Mars” – Elon Musk showed record tests of the largest SpaceX rocket

A little closer to Mars Elon Musk showed record

Elon Musk has confirmed that SpaceX has completed a lengthy static fire test of the Booster 7 Raptor 2 engines on the orbital launch pad at Starbase.

On Tuesday, SpaceX tested its super-heavy rocket for about 12 seconds, making it the longest launch to date. The test, which fired 11 of the 33 Raptor 2 rocket engines, passed without any explosions or other problems, which is an excellent result.

Earlier this month, SpaceX fired 14 Raptor 2 engines on that booster for a few seconds, so yesterday’s test didn’t set a new record for most engines tested. However, this “long” test was the longest ever to run so many Raptor 2 engines at the same time.

Earlier, SpaceX founder Elon Musk said the next step would be to fire some of the Super Heavy engines for about 20 seconds to test autogenous boost. This method of pressurizing fuel tanks uses gases generated aboard the rocket rather than a separately loaded inert gas such as helium.

It looks like SpaceX still has a couple of key tests to complete before the super-heavy Starship rocket launches from the Starbase site in South Texas. SpaceX is expected to conduct at least a brief test run of all 33 Raptor engines at the same time to ensure that the entire complex is fueled and pressurized in the rocket’s propulsion system. The Starship will then be installed on top of the Super Heavy for final testing.

Samsung is preparing a smartphone that will be weaker than its predecessor two years ago. Galaxy M54 will receive SoC Exynos 1380

Samsung is preparing a smartphone that will be weaker than

Smartphone Samsung Galaxy M54 lit up in the Geekbench database. Unfortunately, as previously reported, he will not receive any SoC Snapdragon 888, although this is expected.

Samsung’s mid-budget novelty will receive the same platform as the Galaxy A54. Probably, the Galaxy A34 will also receive it.

We are talking about the not yet presented Exynos 1380, which will replace the Exynos 1280. In the benchmark, the new SoC scores 750 and almost 2700 points in single-threaded and multi-threaded modes, respectively. And this is almost the level of Snapdragon 778G, that is, this is an excellent result for a mid-budget smartphone. True, we are only talking about processor performance, and we do not yet know which GPU the new SoC will receive.

It is also worth noting that the Galaxy M52 was also based on the Snapdragon 778G, and the Galaxy M53 received a slightly less productive Dimensity 900. Thus, the Galaxy M54 model, at least in terms of the processor part, will be slightly inferior even not to its predecessor, but to the device two years ago.

Bullitt Group and MediaTek want to launch a satellite enabled smartphone

The British manufacturer Bullitt Group, which produces devices under the brands CAT and Motorola, intends to release a smartphone with satellite communications. They want to implement this project together with the Chinese chipmaker MediaTek.

It is assumed that the new smartphone will provide calls and text data via satellite, although it is not yet clear how this will work. The device itself will be released in the first quarter of 2023.

The novelty has been developed for two years, so the project is nearing completion. According to Bullitt Group co-founder Richard Wharton, previously the seamless integration of satellite communications into a smartphone was accompanied by problems, but now they are solved.

The new phone will be the first to use MediaTek’s 3GPP NTN chipset. The software will keep track of what type of connection is currently being used – Wi-Fi or cellular network. The connection to the satellite will be carried out only in the absence of both of these options.

It is claimed that the time to connect to the satellite and send a message is about 10 seconds. This is longer than a regular connection, but still pretty fast.

Note that Apple already has this and Samsung will soon have it.
