China’s Chang’e-5 probe returns to Earth with lunar samples

China’s Chang’e-5 probe landed after a mission to grab samples from the moon.

Published

on

For the first time since the 1970s, Reuters reports a mission has brought samples from the moon back to Earth. China’s capsule separated from its orbiter and landed in Inner Mongolia at about 2 AM local time. According to China’s Xinhua news agency, its parachute opened as planned and the capsule has been recovered by a search team.

It’s being airlifted to Beijing where it will be opened. China’s space agency saw this mission as a step toward crewed lunar missions, and the establishment of a base on the moon. This mission launched in late November, aiming to collect four pounds of samples from an area that’s younger than the area Apollo astronauts visited in the 60s and 70s.

LG’s OLED smart TVs are some of the best you can get, but you’ll have to shell out quite a bit of money for one. While the company will begin rolling out its 2021 OLED TV sets later this quarter, a solid 2020 model is hundreds off at Amazon. Now you can get the 55-inch LG CX OLED smart TV for $1,350 — that’s $650 off and close to the lowest price we’ve seen it. Amazon’s default sale price is $1,396, but there’s a coupon on the product page you can clip for an extra $47 off, bringing the final cost down to $1,350. If you’re a My Best Buy member (it’s free to sign up), you can get the same price there, too.

The CX TVs are part of LG’s midrange OLED collection and they feature the company’s a9 Gen 3 AI Processor 4K, 120Hz refresh rates and support for NVIDIA G-SYNC, AMD FreeSync, Dolby Vision IQ, Dolby Atmos and more. They run webOS and come with a “magic remote” that supports voice commands, but if you have an Alexa or Google Assistant device in your home, you can control the TV with either of those virtual helpers, too. And being OLED sets, these TVs have some of the best color reproduction and blackest blacks you’ll find.

But as mentioned at the top, LG’s latest OLED sets will be coming out soon and they do have a number of new features that the CX line doesn’t have. The new C1 series, the new version of the CX family, will have a Gen 4 processor, updated LG Sound Pro, a new version of webOS with enhanced ThinkQ AI and a new Game Optimizer that promises 1 millisecond response times, low input lag and HDMI 2.1 support.

If you’re serious about getting the best OLED set possible that also has all of the latest gaming technology, you may want to wait for the 2021 models to come out. US pricing is unclear right now, but we do know that a 55-inch C1 set will run €2000 in Europe (which converts to $2,420 in the US, but we expect the starting price to be a bit lower than that). But if the 2020 CX OLED sets have all of the features you were looking for in a new TV, now’s a good opportunity to grab one at a great sale price.

SpaceX launched 60 more Starlink satellites but failed to stick the landing

SpaceX successfully launched another 60 Starlink internet satellites today, but the first stage missed its drone ship landing.

Published

on

SpaceX successfully launched another 60 Starlink internet satellites today for 1,145 in total, bringing it close to its initial goal of 1,440. However, in a rare miss, the Falcon 9’s first stage booster failed to land on the “Of Course I Still Love You” drone ship, presumably falling into the ocean instead. “It is unfortunate that we did not recover this booster but our second stage is still on a nominal trajectory,” said SpaceX engineer Jessica Anderson.

SpaceX has yet to say what happened to the booster (B1059, RIP), but it appeared to encounter an issue near the end of its landing burn. It had already flown two ISS resupply missions, launched a US spy satellite and Argentina’s Earth-observing satellite, and boosted another Starlink mission. While B1059 failed to come home for its sixth mission, SpaceX has always said that the primary launch mission is key and the landings are more or less a bonus.

Despite the failure, SpaceX may launch another 60 Starlink satellites as early as this Wednesday. Elon Musk said that around 500-800 satellites would need to be in orbit before its internet service could roll out. While the initial goal was around 1,440 satellites, SpaceX eventually plans to launch 12,000 in total.

Public beta tests for Starlink internet began in late 2020 for people in the US, Canada and the UK, with more than 10,000 customers already using the service in the span of three months, according to a SpaceX FCC filing. SpaceX has started taking $99 deposits for the service and recently told the Australian government that it would be able to cover the main continent in early 2021 and external territories by 2022.

Hubble researchers find a gaggle of small black holes

Hubble telescope researchers have found a concentration of small black holes — the first studied in significant detail.

Published

on

Larger black holes may be the usual attention-getters, but the smaller ones may be at least as important. A team using the Hubble Space Telescope has discovered a concentration of small black holes in the NGC 6397 globular star cluster (pictured above) 7,800 light-years away — the first to have its mass and extent recorded. While the researchers had hoped to find an elusive intermediate-mass black hole, this represents a breakthrough of its own.

Part of the challenge came from determining the mass. Scientists used the velocities of stars in the cluster, gathered over several years from both Hubble and the ESA’s Gaia observatory, to find the masses of the black holes. The normally invisible bodies tugged stars around in “close to random” orbits rather than the neatly circular or elongated paths you’d normally see with black holes.

The group likely formed as the black holes fell toward the cluster’s center through gravitational interactions with smaller stars. Heavier stars tend to gravitate toward the middle even when they haven’t collapsed into black holes.

The findings could expand humanity’s understanding of black holes and the phenomena they create. A bunch like this may be a key source of gravitational waves, for instance. So long as researchers can collect more data, this surprise discovery might pay plenty of dividends.
