Major gravity experiment recreated aboard a satellite
Posted by Genevieve Klien in category: space travel
A spacecraft was used to “drop” two objects and test their rate of fall. The new, super-precise findings confirm objects will fall at the same rate (in the absence of air resistance) — and that when it comes defining the effects of gravity, Einstein got it right.

Skycorp planning to make space industries
Posted by Klaus Baldauf in category: space travel
The moon is largely made up of metal oxides that could yield new supplies of platinum — perhaps enough to drive prices for the precious metal down to $300 from $1,400 an ounce today. Processing metals on the moon does not require chemicals. Different levels of heat can be used to make different metals. Cheaper platinum will make fuel cells that are so much more effective than combustion engines.

NASA X-Ray Navigation System Aims to Be a Galactic GPS for Space Exploration
Posted by Genevieve Klien in category: space travel
The navigation system uses x-ray light emitted from pulsars the same way global positioning systems use atomic clocks, which could eliminate the need for costly ground-based guidance systems.

Astronomers Detect Almond-Scented Molecule That Will Help Solve Interstellar Radiation Mystery
Posted by Genevieve Klien in categories: particle physics, space travel
There’s an unidentified source of infrared throughout the universe. By looking at the specific wavelengths of the light, scientists think that come from carbon—but not just any carbon, a special kind where the atoms are arranged in multiple hexagonal rings. No one has been able to spot one of these multi-ring “polycyclic aromatic hydrocarbons,” or PAHs in space—even though the infrared emissions imply that these PAHs should make up 10 percent of the universe’s carbon. Now, scientists have found a new hint.
A team of researchers in the United States and Russia are now reporting spotting a special single-carbon-ring-containing molecule, called benzonitrile, with a radio telescope in a part of space called the Taurus Molecular Cloud-1. Benzonitrile only has one hexagonal ring of carbon, so it’s not a poly cyclic aromatic hydrocarbon itself. But it could be a potential precursor and could help explain the mysterious radiation.
Before you even ask, yes, this “aromatic” benzonitrile molecule has a smell. “I can tell you from personal experience it smells like almonds,” study first author Brett McGuire from the National Radio Astronomy Observatory told Gizmodo, who has encountered the molecule in the lab.

America’s space program has long held a special place in the public’s imagination, but NASA missions are limited by budget constraints. NASA must use its funding wisely to implement balanced, cost-efficient programs to develop enabling technologies, such as technologies to power future NASA missions. Speaking as the former project manager of three successful missions — Voyager, Galileo, and Cassini — and the canceled Prometheus-Icy Moons Orbiter, I have a unique perspective to share.

Sorry Sci-Fi Fans, Real Wars in Space Not the Stuff of Hollywood
Posted by Klaus Baldauf in categories: law, military, space travel
WASHINGTON — The public’s idea of a war in space is almost entirely a product of Hollywood fantasy: Interstellar empires battling to conquer the cosmos, spaceships going head to head in pitched dogfights.
The reality of how nations will fight in space is much duller and blander. And some of the key players in these conflicts will be hackers and lawyers.
Savvy space warriors like Russia’s military already are giving us a taste of the future. They are jamming GPS navigation signals, electronically disrupting satellite communications links and sensors in space. Not quite star wars. [The Most Dangerous Space Weapons Concepts Ever].
