Earlier today, the China National Space Administration's Chang'e 4 landed a rover on the far side of the moon for the first time. Blocked from direct communication with the Earth, the lander and rover will depend on China's Queqiao communication satellite launched in May. From the New York Times:
“This is a major achievement technically and symbolically,” said Namrata Goswami, an independent analyst who wrote about space for the Defense Department’s Minerva Research Institute. “China views this landing as just a steppingstone, as it also views its future manned lunar landing, since its long-term goal is to colonize the moon and use it as a vast supply of energy.”
The place the probe is exploring, Dr. Goswami said, could become a future refueling base for missions deeper into space in the way “navies viewed coaling stations, for purposes of refueling and resupply.”
The instruments aboard the lander and the rover include cameras, ground-penetrating radar and spectrometers to help identify the composition of the area, which was formed by a meteorite. Scientists hope the rocks and dirt in the area will add to the understanding of the moon’s geology.
The lander will also conduct a biology experiment to see if plant seeds will germinate and silkworm eggs will hatch in the moon’s low gravity.
In a new interview with the Journal of the American Medical Association above, Anthony Fauci, National Institute of Allergy and Infectious Diseases (NAID), said he expects the US will have 100 million doses of a COVID-19 vaccine before the end of the year. “Then, by the beginning of 2021, we hope to have a couple […]
Just for kicks, Paul Rule, 66, participated in a study launched by the Cambridge Natural History Society that enlisted citizen scientists and nature-lovers to help deepen knowledge of the flora and fauna in Cambridge, England. Rule recorded nearly 600 different animal species in his “ordinary” city garden, including an elephant moth like the one seen […]
Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)
The world is holding its collective breath. As states begin cautiously reopening, no one is sure exactly what to expect. But one thing is clear: most Americans are worried about their bank accounts. By the end of March, the average American household was spending 40 percent less on their credit cards than they were one […]
Over 25 years, eBay has carved out its space as the commerce hub of choice online. With 182 million users worldwide, that works out to about 35 percent of all US mobile users who shop those eBay storefronts. But did you know there are usually around 1.3 billion — with a B — active for-sale […]
Software apps are a dime a dozen. Well, if you’re going by their actual monetary cost, maybe not really. But considering how useless some poorly conceived, poorly executed apps are at doing the job you actually downloaded them to accomplish, it isn’t a stretch to think that many apps aren’t even worth a free download.
