The Aging Spacecraft of Deep Space
The twin Voyager spacecraft took off in 1977, carrying scientific instruments and golden records stuffed with information. Millions of miles away, they still communicate with Earth. They still collect data. But they are aging. The spacecraft, traveling in slightly different directions, weaken every year. Their thrusters, which keep them steady, are degrading. Their power generators produce about 40 percent less electricity than they did at launch.
It's not realistic to cut US-China economic ties. We should compete and win instead.
A common mistake in Washington is thinking about U.S.-China competition through a Cold War mentality that views Beijing as an adversary that we can contain and isolate like the Soviet Union. The United States and China are economically intertwined in a way that America and the Soviet Union never were and that America and Russia are not today. Regardless of presidential tweets saying that "we don't need China" andthatU.S. companies should find alternative markets, decoupling from China in the global economy is simply unrealistic and would be in neither country’s interest.
Earth's Atmosphere Could Become the Lens of a Massive Telescope
The conventional wisdom is that if you want to look at more distant objects in the universe, you need a bigger telescope. What if you didn’t have to build one, though? A new analysis claims it may be possible to use the Earth’s atmosphere as a giant lens to observe far-away stars and galaxies on the cheap. The process may even work in reverse to send signals to distant locales.
5 things Leonardo da Vinci invented that we still use today
Leonardo da Vinci was the ultimate Renaissance man. That’s true in the literal sense, because da Vinci did, in fact, live and create during the Renaissance. But it’s true figuratively as well. He achieved so much and across such a wide variety of disciplines that it boggles the mind.
The moon rock that turned out to be from Earth
All is not what it seems in the world of lunar samples. If you put a moon rock alongside one from Earth, they usually don't have a lot in common. So when Curtin University planetary scientist Professor Alexander Nemchin looked closely at a moon rock in his laboratory, he realized something wasn't right.
Air Force Tests Contraption That Can Turn Any Plane Into a Robot Plane
Air Force scientists have announced that they had tested a robot kit that can turn virtually any plane into a self-piloting drone, through a program called ROBOpilot. Why is that important? For starters, planes and drones are expensive. The drone shot down over Iran last month cost $220 million.
New Hope for Cancer Patients Through Photobiomodulation (PBM)
A new era of cancer treatment just dawned, giving hope to America's 15.5 million cancer survivors, and the estimated 1.8 million who will be diagnosed with cancer this year. On June 22, 2019, the Multinational Association of Supportive Care in Cancer (MASCC) recommended the use of Photobiomodulation (PBM) as the standard of care for preventing and treating the side effects of radiotherapy and chemotherapy.
Huawei faces a 'life or death crisis,' CEO says as he lays out 'battle' strategy amid US pressure
Huawei is facing a “life or death crisis” amid continued pressure from the U.S. government, its founder and CEO told employees, as he laid out a strategy for the Chinese telecommunications giant going forward. In a memo to employees of Huawei’s networking division seen by CNBC, Ren Zhengfei described the company’s current situation as a “battle.”
A massive collision may have made Jupiter's core so weird
A giant impact 4.5 billion years ago could be the reason Jupiter’s core is stranger than astronomers expected. Astronomers thought that Jupiter began as a rocky and icy planetary embryo that later formed its massive gaseous envelope, drawing in hydrogen and helium from the solar nebula by virtue of its huge gravity. This would mean there was a relatively clear delineation between the solid core and the gas surrounding it.
Looks Like Elon Musk Is Serious About Nuking Mars
SpaceX's billionaire founder and CEO teased the idea in 2015 during an appearance on "The Late Show with Stephen Colbert," explaining that vaporizing Mars' ice caps would be a good way to warm the planet enough for human colonists to live relatively comfortably. Musk floated the concept again last week via Twitter, initially saying simply "Nuke Mars!" and then "T-shirt soon."
