In 2018, being available at all times is critical. But you aren’t truly available if your mobile device, laptop, or desktop loses power, right? There are portable battery packs and power backup devices abound nowadays, but many of them are designed for recharging only smartphones and smaller devices. Typically, battery packs provide between 3,000 and 5,000 […]

The Chinese Space Station Has Crashed in the Pacific. Why Was It So Hard to Track?

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

If a massive space station falls out of the atmosphere into the Pacific Ocean, with no one there to witness it, does it make a sound?

That’s no hypothetical question. We’re asking about Tiangong-1, the Chinese space station that finally “de-orbited” from space and into the Pacific around 8 PM Eastern time on April 1.

Let’s be honest — “de-orbited” is a polite way of saying “free-fall.” Scientists could neither alter nor even really track Tiangong-1’s descent. That could be a problem in a future — an atmosphere more packed with spacecraft presents a (slightly) higher risk for humans on the ground.

We’ve anticipated Tiangong-1’s homecoming since 2016, when abnormalities in the space station’s orbit suggested that the Chinese space agency had lost control of it. It took a few months for authorities to admit that the craft was out of their reach. Normally, a space agency will retire a satellite by purposely guiding it into the atmosphere, at an angle and speed such that it burns up completely or re-enters Earth’s atmosphere far from human populations.

That makes Tiangong-1’s spinning, erratic descent less than ideal.

Scientists weren’t exactly sure when and where the craft would land until the moment it did so. Indeed, the space station’s case highlights the fact that scientists still don’t have the capacity to wrangle the significant number of variables that factor into tracking and modeling such situations.

Around noon Eastern time on April 1, seven hours before the craft actually fell, the European Space Agency (ESA) had reached the limit of what it could forecast. And there still a pretty big window for when and where the station would re-enter.

“With our current understanding of the dynamics of the upper atmosphere and Europe’s limited sensors, we are not able to make very precise predictions,” said Holger Krag, head of ESA’s Space Debris Office, in an agency blog about Tiangong-1.

Note: we do not want to overstate the odds of being hit by falling spacecraft. Space junk falls out of the atmosphere all the time, and only one person has ever been hit by it. For the Tiangong-1, the odds that the falling space station would have hit any single human on Earth were still 1 in 1 trillion, lower than your yearly odds of being struck by lightning.

But that may change in the coming years. The growing space industry has promised to put a number of new spacecraft into orbit around Earth in the next decade, including thousands of new satellites. As we increase the number of objects in space, the overall probability of something falling out of the sky into a populated area will increase. At the moment, nobody has a way to zap space junk (or incoming meteors, for that matter) that might pose a threat, and it doesn’t seem likely that we’ll get one anytime soon.

Instead, as ESA’s Krag implies, research could help a lot. If we could better understand how the upper atmosphere behaves, we could better model where a falling object would land, and potentially warn people in the area if needed.

Unfortunately, that doesn’t seem likely. The sort of basic research that would improve scientists’ understanding of the atmosphere is chronically under-funded, and in the U.S., happens in agencies to which the White House doesn’t allocate many resources.

Basic research into the upper atmosphere isn’t nearly as sexy as as falling space junk, but it could one day save a lot of people some logistical — and potentially physical — headaches.

China’s out-of-control space station harmlessly breaks up over the Pacific Ocean

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

China’s out-of-control space station — Tiangong-1 — has at last plunged through Earth’s atmosphere and landed somewhere over the southern Pacific Ocean. The spiraling spacecraft made its descent at around 8:16PM ET on April 1st, according to US Strategic Command, which was able to confirm the exact point of reentry along with organizations in eight other countries. The vehicle’s fall puts an end to the space station’s seven years in orbit, and it managed not to hit any populated areas on the way down.

It was hard to know exactly where Tiangong-1 was going to make its final descent, which is the case for most falling space debris. Sunday afternoon, trackers were able to narrow down the time of the vehicle’s reentry to a three- to…

China’s spiraling space station will plunge to Earth in about a week

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

After a couple years of anticipation, China’s first human space station — Tiangong-1 — will drop out of its orbit in about a week and plunge into Earth’s atmosphere. The European Space Agency has pinpointed the vehicle’s reentry date to sometime between March 30th and April 2nd, with the event most likely happening on April Fools’ Day. Once the station descends, it will finally put an end to all of the anxiety over the location of this vehicle’s landing.

Tiangong-1’s fall has caused a lot of concern because China no longer has control of the space station. The country’s engineers can’t just fire up the vehicle’s engines again and deposit it over open ocean. Tiangong-1 is pretty heavy, too. It weighed nearly 19,000 pounds (8,500…

Apple Hosting Developer Workshop at Station F Parisian Incubator

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

Apple next week plans to host a workshop for developers at the Station F startup incubator in Paris, France. The event will take place on Friday, March 23 according to French site Mac4Ever.

A limited number of French developers have been invited to attend the workshop, which will consist of a two hour workshopping session followed by a question and answer period.

This special workshop will teach you to create amazing apps for Apple platforms and make the most of your presence on the App Store. After the workshop, you’ll have the opportunity to speak with Apple experts and fellow participants.

Station F is one of the largest centers for entrepreneurs in Europe, and Apple first became involved with the incubator in October of 2017 following Apple CEO Tim Cook’s visit to Paris.

Apple reportedly has a small team at Station F to help developers create, validate, and manage their iOS apps. Station F memberships start at €195 per month, but there are discounted yearly memberships available along with a free program for those who can’t afford the fee.

Tesla files permit for ‘restaurant and Supercharger station’ in Santa Monica

Elon Musk’s dream of building a 1950s-themed Tesla Supercharger station, complete with rockabilly music and roller skates, is closer to becoming a reality after The Drive noticed a permit filed with the city of Santa Monica for a “Tesla restaurant and supercharger station.”

A Tesla spokesperson wouldn’t confirm whether an “old school drive-in, roller skates & rock restaurant” was indeed the plan for this particular location, but allowed that it was possible. (Tesla’s PR department spends an inordinate amount of time scrambling to explain their boss’s enigmatic tweets.)
