Adstoppi Blog | China has deorbited its experimental space station

Published by:


A little over a year after its first space station crashed down over the Pacific Ocean, China has deorbited its second, the Tiangong-2. It entered Earth’s atmosphere and burned up over the South Pacific ocean on Friday.

Unlike the Tiangong-1 station’s uncontrolled descent, China deliberately brought the Tiangong-2 down to Earth in a controlled fashion over the Pacific, where there wasn’t any risk of it hitting people.

China launched the space station in September 2016, and quickly sent up a pair of taikonauts, Jing Haipeng and Chen Dong, to conduct a variety of experiments on a 30 day mission. China launched a second, uncrewed mission in April 2017 to refuel the station to test out a new spacecraft and conduct some “robotic demonstrations.” That was the last mission to the station, which was never intended as a permanent habitat in orbit.

While the station is no longer in orbit, it proved to be a useful project for China, which has been steadily working to gain a better foothold in space in the last decade. Along with the Tiangong-1, the two stations provided the Chinese space program with valuable experience in orbit. They demonstrated not only that they could launch and sustain hardware in space, but also dock crewed and uncrewed vehicles to them — vital lessons for any human spaceflight program. China had proposed a third station, the Tiangong-3, but it was never constructed or launched.

Tiangong-2’s deorbiting doesn’t mean that China’s ambitions in orbit are over. The country is planning on constructing another station in orbit, with the first section, the Tianhe-1 module, scheduled for launch in 2020.

The riches of Silicon Valley have enabled some extravagant and quixotic projects, but they’ve got nothing on what oil money can do. A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia’s biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students. The details are stunning. It’s a mixture of dystopian fiction (AI surveillance cameras everywhere!) and childish imaginings (let’s build a robot dinosaur park!). Taken together, the plans remind of you what a dedicated nine-year-old can achieve in Minecraft. Yes, the scale and ambition are impressive, but it’s not like you could do this in real life, right? These are only proposals, of course,...

President Trump violated the First Amendment by blocking his critics on Twitter, a federal appeals court ruled today, shutting down the White House’s request to overturn a lower court’s decision. Several Twitter users who were blocked by @realDonaldTrump, represented by the Knight First Amendment Institute at Columbia University, filed suit in 2017, arguing that their constitutional right to engage with officials in a public space was being violated. The dispute has turned into whether Trump’s account, which he operated before becoming president, is still a private account or an official one and whether Twitter’s design created a “public forum” for speech. The lower court found last year that Trump used the account in an official capacity and that blocking users was an...

The death toll from the new coronavirus outbreak in China rose Monday as the government, scrambling to contain the epidemic, extended the Lunar New Year holiday to try to stop people from traveling. The death toll stood at 106, according to health officials who have warned that the spread of the virus was accelerating. Officials with China's National Health Commission said there were 4,515 confirmed cases up from 2,744 confirmed cases of which 976 are considered severe.

Cases of the virus have been reported on four continents, including the United States, where a fifth case was confirmed Sunday. All the U.S. cases are patients who have recently traveled from Wuhan in Hubei province....

High cholesterol causes and symptoms

Published by:

Many people are completely unaware that they have high cholesterol, which is why it’s known as the silent killer. “There are no symptoms of high cholesterol,” says Dr. Dermot Neely, who runs a specialist lipid clinic in Newcastle upon Tyne. “The only real symptom is a blocked artery, which causes a stroke or heart attack. In severe cases, you can get cholesterol deposits in the tendons or around the clear part of the eye, but a doctor would rarely notice these during an examination.” So what is it? Cardiovascular diseases are ­responsible for 38% of male and 37% of female deaths before the age of 75, with high cholesterol a serious risk factor. But it’s not all bad. “We all have cholesterol in the blood, and we all need it to be a healthy human,” says Dr. Neely. “It’s...

A U.S. citizen diagnosed with novel coronavirus has died in China in what appears to be the first death of an American from the virus that has sickened tens of thousands of people in China and killed more than 700, a U.S. embassy spokesperson said. "We can confirm a 60-year-old U.S. citizen diagnosed with coronavirus died at Jinyintian Hospital in Wuhan, China on Feb. 6," a spokesperson for the U.S. Embassy in Beijing said. "We offer our sincerest condolences to the family on their loss. Out of the respect for the family's privacy, we have no further comment," the spokesperson said. The New York Times first reported the death of the American in Wuhan. China's national health commission said that as of Saturday morning local time, there had been 722 deaths from the virus in the mainland....

Qualcomm fined $272M in latest EU antitrust fine

Published by:

The EU has fined Qualcomm €242 million (around $272 million) for selling 3G modem chips at predatory prices in an attempt to drive a competing supplier, Icera, out of the market. The European Commission says that the company used its market dominance to sell chips meant for mobile internet dongles at below cost between 2009 and 2011. Today’s announcement marks the end of the EU’s nearly four year long investigation into Qualcomm’s actions. Announcing the fine, the EU’s Competition Commissioner Margrethe Vestager, said that “Qualcomm’s strategic behavior prevented competition and innovation in this market, and limited the choice available to consumers in a sector with a huge demand and potential for innovative technologies.” The EU’s investigation found that Qualcomm sold...

LOS ANGELES Federal investigators on Friday ruled out engine failure as a possible cause of the helicopter crash that killed basketball legend Kobe Bryant, his 13-year-old daughter Gianna, and seven others. The chartered Sikorsky S-76B helicopter that crashed into a hill Jan. 26 had two engines that burned in the aftermath, the National Transportation Safety Board said in an investigative update. "Viewable sections of the engines showed no evidence of an uncontained or catastrophic internal failure," the update states. After the crash, the NTSB has launched a Go Team to the site in an attempt to find the cause. The update reported that a witness to the crash said the area was "surrounded by mist," in the NTSB's paraphrasing, when the Sikorsky was spotted moving fast, descending and...

Apple buys Intel's smartphone modem business

Published by:

Apple will acquire “the majority” of Intel’s smartphone modem business for $1 billion, the two companies announced today. Around 2,200 Intel employees will join Apple, and Apple will acquire IP and equipment from Intel as well. The transaction is expected to close toward the end of the year. Intel won’t be getting out of the modem business entirely. It’ll still be able to develop modems for PCs, Internet of Things devices, autonomous vehicles, and seemingly anything that’s not a smartphone. Intel CEO Bob Swan said the acquisition will allow the company to focus on developing other 5G technologies. The acquisition means that Apple is now well on the way to producing its own 5G modems for its smartphones, rather than having to rely on Qualcomm for the hardware. Apple only...

FogCam, which is believed to be the oldest webcam on the internet, will be shut down at the end of August after 25 years of near-continuous operation. Jeff Schwartz and Dan Wong, who set up the webcam while students at San Francisco State University back in 1994, announced the decision via Twitter, where they thanked their viewers and the university for their support over the years. In an interview with SFGate, Schwartz provided more details on the decision to take the webcam offline. “The bottom line is that we no longer have a really good view or place to put the camera,” he said, “The university tolerates us, but they don’t really endorse us and so we have to find secure locations on our own.” Although the webcam feed will be gone, the site it’s hosted on will stay online...
