    Interstellar Trade Is Possible In this post, we will detail a method for developing interstellar trade using near-future technologies and commercially realistic requirements. We will then look at the various outcomes, challenges and development models that will follow the first interstellar operation. There is now a Summary at the end of the post. A tough taskTravel between stars is hard. The distances are measured in trillions of kilometers and the space between destinations is not really empty. Attempting the crossing at interplanetary speeds is ludicrously slow; the only way is to reach velocities measured in percentages of the speed of...

    “Scott’s telomeres (endcaps of chromosomes that shorten as one ages) actually became significantly longer in space,” NASA researchers wrote in a statement. The space agency added that Kelly had hundreds of “space genes” activated by the year-long flight which reportedly altered the astronaut’s “immune system, DNA repair, bone formation networks, hypoxia, and hypercapnia.” While Scott Kelly’s height and 93 percent of his DNA returned to normal after returning to Earth, NASA confirmed that seven percent of his genes have remained changed and may stay that way. “This is thought to be from the stresses of space travel, which can cause...

    President Trump told a military crowd near San Diego on Tuesday that he believes the U.S. may need to create a new military branch for outer space. "My new national strategy for space recognizes that space is a war-fighting domain, just like the land, air, and sea. We may even have a space force, develop another one: Space Force." Trump said in a speech at the Miramar Marine Corps Air Station. "We have the Air Force; we'll have the Space Force. We have the Army, the Navy," he continued. "You know, I was saying it the other day, because we're...

    An out-of-control Chinese space station with 'highly toxic' chemicals onboard that is currently hurtling toward earth may crash into lower Michigan, it has been revealed. It is believed China's first prototype station, Tiangong-1, will come crashing back to the planet around April 3, experts say. US research organization Aerospace Corporation revealed that parts of southern Lower Michigan are among the regions that have the highest probability of being hit by falling debris, according to
  • What scientists found trapped in a diamond: a type of ice not known on Earth

    Trapped in the rigid structure of diamonds formed deep in the Earth’s crust, scientists have discovered a form of water ice that was not previously known to occur naturally on our planet. The finding, published Thursday in Science, represents the first detection of naturally occurring ice-VII ever found on Earth. And as sometimes happens in the scientific process, it was discovered entirely by accident. Ice-VII is about one and a half times as dense as the regular ice we put in our drinks and skate on in winter, and the crystalline structure of its atoms is different as well. In...

    At the beginning of a cabinet meeting yesterday Trump spent some time talking about the recent successes in commercial space. Not unusually, Trump gets some details wrong but understands the essentials, much to the terror of the big space contractors of SLS (Boeing) and Orion (Lockheed Martin). SpaceX will charge $90 million for the launch of a reused Falcon Heavy (using three reused first stages). Estimates for the cost of a single SLS launch are difficult to estimate.

    China’s Tiangong-1 is expected to re-enter the atmosphere and crash into Earth in just a few weeks, scientists have warned. The Aerospace Corporation, a California-based non-profit research and development organization, predicted the 8.5-ton space station will collide into the earth's atmosphere in the first week of April, with error of margin at a week on either side. The European Space Agency estimates the module will crash sometime between March 24 and April 19. Although experts have not yet determined exactly where the out-of-control module will land, an Aerospace report detailed that it will likely re-enter somewhere in the northern U.S....

    The concept of what would become the Hubble Space Telescope was first envisioned after World War II, when astronomer Lyman Spitzer and a handful of scientists began a fifty year struggle to build the first space telescope capable of seeing beyond Earth's atmospheric veil. Robert Zimmerman, author of "The Universe in a Mirror: The Saga of the Hubble Space Telescope and the Visionaries Who Built It," takes us behind the scenes, explaining how some of Hubble's advocates sacrificed careers and family, and how others devoted their lives to the telescope only to have their hopes and reputations shattered when its...
  • China's Big Space Lab May Fall to Earth This Month

    The European Space Agency (ESA) has issued a new re-entry forecast for China's Tiangong-1 space lab. The 8.5-ton spacecraft is now expected to fall into Earth's atmosphere between March 24 and April 19, though ESA officials stressed that this is a rough estimate. "Re-entry will take place anywhere between 43 degrees north and 43 degrees south (e.g. Spain, France, Portugal, Greece, etc.)" latitude, officials with the Space Debris Office at ESA’s European Space Operations Center in Darmstadt, Germany, wrote in an update last week. "Areas outside of these latitudes can be excluded. At no time will a precise time/location prediction...

    Astronomers have detected a massive stellar flare -- an energetic explosion of radiation -- from the closest star to our own Sun, Proxima Centauri, which occurred last March. This finding raises questions about the habitability of our Solar System's nearest exoplanetary neighbor, Proxima b [an Earth-like planet], which orbits Proxima Centauri.

    How can a rocket engine achieve more than a 100-percent thrust? Well, RS-25 engines were first designed more than 40 years ago, for use with NASA's space shuttle, and the power level they were capable of achieving at the time is the margin known as 100-percent thrust, according to NASA. RS-25 engines are former space shuttle engines that have been modified to perform more powerfully than ever before. "Increased engine performance is crucial for enabling SLS missions to deep space as the rocket evolves to be larger and carry astronauts and heavy cargo on a single flight," NASA officials said...

    Aluminium oxynitride or AlON is a ceramic composed of aluminium, oxygen and nitrogen. It is marketed under the name ALON by Surmet Corporation. AlON is optically transparent (≥80%) in the near-ultraviolet, visible and midwave-infrared regions of the electromagnetic spectrum. It is 4 times harder than fused silica glass, 85% as hard as sapphire, and nearly 15% harder than magnesium aluminate spinel. Since it has a cubic spinel structure, it can be fabricated to transparent windows, plates, domes, rods, tubes and other forms using conventional ceramic powder processing techniques. ALON is the hardest polycrystalline transparent ceramic available commercially. Combination of optical...

    What does a midlife crisis look like in the 21st century? Frittering away your life savings on a red sports car is so last century. Instead, today’s man who is grappling with the limitations of his mortality spends $90 million on a rocket to launch a $100,000 electric car, helmed by a robot by the name of “Starman,” into space. “We want a new space race,” SpaceX founder Elon Musk said in a press conference shortly after the launch of his company’s Falcon Heavy rocket — and his Tesla Roadster — into space earlier in February. Like a child, he...

    NASA's latest tower for launching rockets has a little bit of a lean, which means it may be able to launch just a single rocket. The cost of this tower boondoggle? Almost $1 billion. The tower in question is the Mobile Launcher designed for NASA’s upcoming Space Launch System, which would become the world’s most powerful rocket once completed in a few years. The tower is supposed to keep the rocket stable and upright on the platform during a launch. The system was built for NASA’s now-defunct Ares I rocket and later repurposed for the SLS. The Mobile Launcher is...

    It’s what scientists have termed a ‘grand minimum’ — a particularly low point in what is otherwise a steady 11-year cycle. Over this cycle, the Sun’s tumultuous heart races and rests. At its high point, the nuclear fusion at the Sun’s core forces more magnetic loops high into its boiling atmosphere — ejecting more ultraviolet radiation and generating sunspots and flares. When it’s quiet, the Sun’s surface goes calm. It ejects less ultraviolet radiation. Now scientists have scoured the skies and history for evidence of an even greater cycle amid these cycles. It’s what scientists have termed a ‘grand minimum’...
