Postponement again: NASA postponed the launch of the Artemis 1 mission to September 27 with a “rezeov” on October 2

NASA has postponed the launch of the Artemis 1 mission to September 27, with a backup date of October 2. This is done to carry out repair and test work before launch.

During pre-launch diagnostics, technicians will test all systems, verify repair results and leaks, as well as test the system for bleed on hard start and correct pre-boosting.

This is not the first transfer. As early as August 29, problems arose with the water of the four engines, which did not cool to the desired temperature due to a hydrogen leak. Then the problem was eliminated, but the start was postponed to September 3.

That day, the launch was canceled 2.5 hours in advance because a fuel leak was discovered. This problem could not be corrected locally.

As part of the mission, it is planned to launch the Orion spacecraft in unmanned mode with 10 cubesats. If everything goes well and the launch is not postponed again, then the ship is planned to be sent to the Moon, where it will spend about 37 days, after which it will return to Earth and splash down in the Pacific Ocean. During the flight of the ship, the level of radiation on board will be monitored.

And earlier, a NASA probe flying to the moon was transferred to a safe mode of operation due to malfunctions.

NASA “landed” the unique Boeing 747SP SOFIA. For 8 years he watched the universe from the stratosphere

NASA landed the unique Boeing 747SP SOFIA For 8 years

Since first flying in 2007, a Boeing 747SP tail number N747NA, modified by NASA into a large flying telescope, has been circling the stratosphere observing the universe in infrared (just like James Webb). But the work of SOFIA (Stratospheric Observatory for Infrared Astronomy, Stratospheric Observatory for Infrared Astronomy) came to an end: on September 28, a unique aircraft completed its last flight.

The SOFIA project at one time proved to be an innovative way to look at the Universe in the infrared. Unlike ground-based telescopes, which find it difficult to “see” through the water vapor of the earth’s atmosphere, SOFIA observed space from a height of more than 12.5 km, which provided a better view compared to ground-based objects.

The SOFIA project started in 1996. The first flight with a 2.7 m telescope installed on board took place in 2010, but the device was fully operational only in 2014. From 2014 to 2019, the flying observatory completed its five-year mission, but the operation of the unique telescope was extended for another three years. All this time, SOFIA has been observing the Moon, planets, and stars. This telescope was able to detect water on the moon’s sunlit surface in 2020.

2022 has been a very productive year for SOFIA. According to FlightRadar24.com, the 44-year-old aircraft made 143 flights.

So, this year, the stratospheric observatory visited South America for the first time: within two weeks, the telescope was deployed in Chile to observe celestial objects that can only be seen in the latitudes of the Southern Hemisphere.

In July, during a storm in New Zealand, the aircraft received frontal damage due to the displacement of a ladder placed outside. After that, the aircraft returned to the base in Palmdale in California, but later performed several more flights. The project is closed due to the fact that its scientific productivity no longer justifies the operating costs.

Nvidia, where are the normal prices for inexpensive video cards? In Europe, prices fell by half of the Radeon RX 6000 models and just two RTX 30 models

Nvidia where are the normal prices for inexpensive video cards

Despite the fact that a few months ago the average prices for video cards were at the level of recommended values, individual models have room for cheaper prices and they are getting cheaper.

Nvidia, where are the normal prices for inexpensive video cards?  In Europe, prices fell by half of the Radeon RX 6000 models and just two RTX 30 models

In particular, affordable AMD models were actively getting cheaper in the first half of the year and now they are generally not getting cheaper, but the more expensive ones continue to fall.

RX6400 RX6500XT RX6600 RX6600XT RX6650XT RX6700 RX6700XT RX6750XT RX6800 RX6800XT RX6900XT RX6950XT
Minimum price on July 26, euro 169 189 279 374 399 439 469 559 659 749 869 1173
Minimum price for today, euro 169 199 269 375 359 429 469 497 589 679 769 899
GTX 1630 RTX 3050 RTX 3060 RTX 3060 Ti RTX 3070 RTX 3070 Ti RTX 3080 RTX 3080 Ti RTX 3090 RTX 3090 Ti
Minimum price on July 26, euro 175 309 379 469 569 669 779 999 1323 1449
Minimum price for today, euro 175 300 379 459 578 679 799 999 1050 1199

For example, as you can see, the Radeon RX 6950 XT, instead of 1173 euros a couple of months ago, now costs only 900 euros, and this is the most productive AMD card and, together with the GeForce RTX 3090 Ti, one of the most productive on the market in general. At least until the start of sales of the RTX 4090. At the same time, just a couple of months ago, the RX 6900 XT cost the same as the RX 6950 XT now, the RX 6800 XT, like the RX 6900 XT, and so on.

Things are not so good with Nvidia cards. Here, only two top models fell in price, however, both are very significant. The situation is worse with other adapters. For example, the popular RTX 3060 is now worth as much as the significantly more powerful RX 6650 XT, and the RTX 3080 Ti is 100 euros more expensive than the RX 6950 XT.

There may be alien life The Juno spacecraft flew just

The Juno spacecraft sent back new photos of Jupiter’s moon Europa. The new ones differ from the previous ones in that they were made during the flight of the apparatus over Europe at a distance of only about 350 km. For comparison, the ISS is above the Earth at an altitude of 417 km.

It is not known how many photographs were taken in total, but if we talk about the closest approach, the device swept past Europe at a speed of 23.6 km / s, so it is unlikely that many photographs were taken during this time.

Now astronomers will be able to compare recent images with earlier ones and see if there are any changes on the surface of the satellite. Unlike many other bodies in the solar system, the surface of Europa can indeed change slightly over a fairly short period, since, according to current ideas, there is a huge ocean under the thick ice crust, and sometimes due to tidal forces, the ice can crack and move.

In addition, scientists need as much data as possible about Europe, since in 2024 the Eupora Clipper should be launched – the first mission to this particular satellite of Jupiter, where, given the available data, there can be the most optimal conditions for the emergence and development of life.
