NASA specialists monitored the operation of the MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment) oxygen generator installed on board the Perseverance rover and confirmed its regular operation at all times of the day and in different weather conditions. This success will significantly accelerate the development of life support systems for future Martian colonies, according to the Massachusetts Institute of Technology (MIT).

The MOXIE oxygen generator on the Perseverance rover has performed so well that it will serve as the basis of life support systems for future Martian colonies.

The atmosphere of Mars is very changeable compared to its terrestrial counterpart. The air density on Mars periodically decreases or increases by about half as the seasons change, and its temperature can drop or rise by 100 degrees Celsius. Therefore, one of the main objectives of our mission was to verify that MOXIE will constantly produce oxygen in all conditions.”, – said the head of the MOXIE project Jeffrey Hoffman.

In the past six years, at the suggestion of Elon Musk, scientists have begun to seriously think about how humanity can begin the process of colonizing Mars and other potentially habitable planets. To do this, as researchers now suggest, two problems need to be solved: to learn how to produce energy, as well as oxygen, water and food, using local resources.

As Hofman and his colleagues note, producing oxygen will be one of the most important yet energy-intensive tasks that the first colonists on Mars will face. To solve it, scientists are developing systems that can extract oxygen from the Martian air and soil. One such instrument, MOXIE, was installed on the Perseverance rover.

The MOXIE system absorbs carbon dioxide, heats it up to 800 degrees Celsius and passes it through a special ceramic material that breaks down CO2 into oxygen and carbon monoxide. As a result, the installation produces about six grams of oxygen per hour, which is comparable to the amount of this gas that is released by one tree in the same time.

This is what MOXIE looks like

The work of the oxygen generator was successfully tested on Mars in April last year, however, according to Hoffman and his colleagues, the work of scientists and the system they created did not stop there. Over the next eight months, the researchers activated MOXIE seven more times and tested the operation of this device at different times of the day and at different times of the year on Mars.

These experiments confirmed that NASA’s life support facility successfully produced a standard amount of oxygen both during the day and at night, as well as at high air temperatures (about minus 20 degrees Celsius) and at low air temperatures (minus 74 degrees Celsius). As a result, MOXIE received about 50 grams of oxygen, and its efficiency almost did not decrease after seven inclusions of this device, which indicates its high durability.

In the near future, Hofman and his colleagues plan to conduct new experiments on Mars, as well as create larger-scale oxygen generators similar to MOXIE, the operation of which they will test during long-term experiments in ground laboratories. These installations, scientists hope, will serve as the basis for the life support systems of the first inhabited Martian bases.

Will the new Intel processors really become much more expensive? Prices for new items lit up a few hours before the announcement

Will the new Intel processors really become much more

Intel Raptor Lake processors will be unveiled in a few hours, but now we have the opportunity to look at prices that may be in line with the recommended ones.

Will the new Intel processors really become much more expensive?  Prices for new items lit up a few hours before the announcement

The fact is that the new items were lit up in the NewEgg store, and marked as recently released. Given the size and status of this network, it is possible that the prices listed there now correspond to those that Intel itself will reveal in a few hours.

And if so, then the same price increase that the company warned about earlier will take place.

  • Core i9-13900K – $660 ($70 more than its predecessor)
  • Core i9-13900KF – $630 ($65 more than its predecessor)
  • Core i7-13700K – $450 ($40 more than its predecessor)
  • Core i7-13700KF – $430 ($45 more than its predecessor)
  • Core i5-13600K – $330 ($40 more than its predecessor)
  • Core i5-13600KF – $310 ($45 more than its predecessor)

Thus, we will get a rise in price by 10-15%. If we talk about competition with AMD, then the Ryzen 5 7600X at a price of $300 is 10% cheaper than the Core i5-13600K, the Ryzen 7 7700X at a price of $400 is more than 10% cheaper than the Core i7-13700K, and the Core i9-13900K at a price of $630 is significantly more expensive than the 12-core Ryzen 9 7900X, but significantly cheaper than the top-end Ryzen 9 7950X. We wrote about the performance of new AMD products yesterday.

New Xiaomi 5000 mAh lipstick mobile battery for 18

Together with the Civi 2 smartphone, Xiaomi today introduced a mobile battery in the form of “lipstick” – it’s easier to describe what the device looks like. However, for the “lipstick” it turned out to be quite large: the length is 94.5 mm, weight – 127 grams.

New Xiaomi: 5000 mAh

On the case there is a button, an indicator and a USB-C port. The device uses a battery size 21700 with a capacity of 5000 mAh. Xiaomi says that Civi 2 can be charged up to 80% with this mobile battery. The maximum output power is 20W (9V 2.25A).

10 year old Samsung Galaxy Galaxy S3 and Galaxy Note 2 received

Samsung Galaxy S3 and Galaxy Note 2 smartphones received Android 13, but not official – as part of the LineageOS project and LineageOS 20 firmware.

10-year-old Samsung Galaxy Galaxy S3 and Galaxy Note 2 received Android 13. True, unofficial

We are talking about an early assembly of LineageOS 20, in which a number of functions do not work: NFC, Bluetooth sound transmission during a call, memory card. Known issues are expected to be fixed as the firmware is updated.

The Samsung Galaxy S3 and Galaxy Note 2 are ten years old, and you should not expect older devices running the latest Android 13 to run smoothly. Both smartphones had flagship specs for their time, but the 1GB and 2GB of RAM in the Galaxy S3 and Galaxy Note 2 might not be enough for a full system at the moment.

Recall that the basic versions of the Samsung Galaxy S3 and Galaxy Note 2 were running Android 4.0.4 and 4.1.1, respectively. Android 4.3 and 4.4.4, respectively, were released as the final software versions for these smartphones.
