NASA was flummoxed last week when the Perseverance rover attempted to collect its first rock core sample only to find the sample tube empty. The missing core was nowhere to be found, so the team had to take a step back and assess the situation on Mars. Now, NASA believes it has , and it’s ready to set course for the next sampling location. The Perseverance rover has a suite of advanced instruments to study the red planet, including 23 cameras, an ultraviolet spectrometer, and ground-penetrating radar. However, you can’t send every possible instrument to Mars. Some of them won’t fit on a rover, and the team might not think to add others until the robot is already off on its mission.
Protecting your expensive hardware from viruses is vital. Without appropriate protections, such as antivirus software, the integrity of your devices can be compromised, making your computer near unusable, and if you can’t fix it yourself, the only options are expensive professional fixes – if it can be fixed at all. Installing a suite of basic protective software is common sense, and will allow you to protect both your private data (files, passwords, browsing history, location, documents, etc) and your hardware from attack. And it’s easy to get started quickly with quality antivirus software. Right now, you can get for the reduced price of $29.99, a hefty reduction of 37 percent off the full purchase price of $47.
Boeing will miss its Starliner launch window, the company has confirmed after a week of uncertainty. Four of the 13 stuck valves that are still not working, so Boeing and NASA have decided to unstack the spacecraft and rocket. Starliner will go back to Boeing’s factory for “deeper-level troubleshooting,” and that means a delay of at least several months. Depending on the root cause of the hardware failure, it could be much longer. Luckily, Starliner won’t have to go far to get disassembled. It’s destined for a facility at Kennedy Space Center very near to the Vertical Integration Facility (VIF) where the spacecraft is currently sitting atop an Atlas V rocket.
Dell’s newly released Vostro 7510 laptop was built for business but has a versatile feature set that just about anyone will enjoy. It has a fast Intel Core i7 processor that can multitask with ease and an Nvidia GeForce RTX 3050 to accelerate image editing work or for playing games, and best of all the system is all sell for just $1,249.00. This high-end Vostro notebook was designed as a high quality work machine. It has powerful processing hardware including an octa-core processor and Nvidia GeForce RTX 3050 GPU. This hardware enables the system to quickly run multiple applications and render content with ease, and it can run games quite well too.
The asteroid known as Bennu is one of a precious few that have been explored by human spacecraft. NASA’s OSIRIS-REx mission spent more than two years hanging around Bennu, and that has allowed scientists to more accurately model its orbit. The bad news is it’s . The good news; it’s still much more likely to miss us. Bennu is a carbonaceous asteroid discovered in 1999 and is generally believed to be the second most dangerous near-Earth . That’s one of the reasons NASA chose it as the target for . Scientists now believe Bennu might have a “rubble pile” structure held together by the modest gravity.
ARM server CPUs have gotten a lot of attention over the last decade, as multiple companies attempted to bring competitive products to market without much success. In the past few years, the situation has changed somewhat. While ARM accounts for just a fraction of the overall server market, companies like Ampere and Marvell are starting to carve out a place for themselves. It’s going to be a few years, however, before they’re much of a threat to x86. That’s the conclusion reached by TrendForce, which also reports that while both AMD and Intel launched new platforms earlier this year, these systems have reportedly only shipped in limited volume.

The old focus on clock speed ended in 2004, when Intel canceled Tejas, Jayhawk, and the 4GHz Pentium 4. One could call 2004-2011 the first multi-core era. The median high-end enthusiast CPU core count rose between 4x and 6x in seven years. From 2011-2017, Intel held core counts steady and focused on improving power consumption at lower TDPs. In 2017, AMD effectively kicked the core count war off again. The growth in six-core and eight-core CPUs has really been something to see.

Over the last few days, Netflix subscribers worldwide have begun to notice that some of their favorite content is missing, and the streaming giant’s so-called “anti-piracy” policies are to blame. Netflix first began cracking down on VPN use , when movie studios began to complain about subscribers’ ability to bypass geographical restrictions by looping through encrypted third-party networks. Many VPN users responded by implementing networks that use residential IP addresses to make it look like they’re legitimate ISP subscribers.
Learning to play music and then reliving your favorite songs with added creativity is a worthwhile pursuit. Creativity can help to soothe stress and give you feelings of accomplishment, allowing for a calmer life with less anxiety. But if you have any skill with music – whatever your instrument might be, from guitar and percussion to singing with just your voice – learning to record and produce your own music is particularly rewarding. Music production is also its own form of art, allowing you to take existing clips and rework them into new creations, and is rewarding in and of itself.
