    For the past ten years, the Sierra Nevada Corporation and NASA have been developing and testing this next-generation space vehicle. When it is ready, this vehicle will not only provide a more cost-effective way of servicing the ISS, it will also help restore domestic launch capability to the United States. On Saturday, November 11th, the Dream Chaser passed an important milestone by conducting a successful free flight test. This took place at Edwards Air Force Base in California, and verified the spaceplane’s ability to glide and land autonomously. This, in addition to verifying several key avionic and flight systems, is...

    After the E. coli samples arrive at the ISS, the experiment will examine how microgravity affects the bacteria's ability to thrive while exposed to antibiotics. Since humans started using antibiotics in the mid-20th century, pathogens like E. coli have evolved new genes that make them increasingly resistant to antibiotics. ... The NanoRacks CubeSat Deployer at the International Space Station will send the bacteria on their way, and the experiment will be conducted autonomously inside the cubesat.  Both naturally occurring and mutant strains of E. coli will be exposed to different concentrations of antibiotics. "The overall purpose of this is to...
  • NASA Discovers Mantle Plume Almost as Hot as Yellowstone Supervolcano That's Melting Antarctica

    A mantle plume producing almost as much heat as Yellowstone supervolcano appears to be melting part of West Antarctica from beneath. Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago.

    The EmDrive propulsion system might be able to take us to the stars, but first it must be reconciled with the laws of physics. Giulio Prisco is a futurist, theoretical physicist, and computer scientist. He writes about science, technology, and the future. He's also a cofounder of Space Cooperative. A tentative theoretical explanation for the mysterious, "impossible" EmDrive propulsion system was published in the Journal of Applied Physical Science International in August. First proposed by British engineer Roger Shawyer, the EmDrive is an asymmetric box that looks like a truncated cone, with a standing microwave field inside that—apparently violating known...

    If confirmed by the Senate, Griffin could become a key voice in advancing U.S. technology in areas where the United States has long dominated — such as aviation and space — and is now being challenged. WASHINGTON — President Trump tapped former NASA Administrator Michael Griffin for a top Pentagon job, giving him a key role in shaping investments in defense and aerospace technologies at a time when other nations are gaining ground on the United States. Griffin’s nomination to be principal deputy undersecretary of defense for acquisition, technology and logistics had been anticipated for weeks, and the White House...

  • NASA and Germany are about to refresh their climate science satellites

    Cassini might have gotten a very emotional send-off at the close of its 20-year journey, but it's not the only long-term space mission being retired this season. Today, the joint NASA-German Gravity Recovery and Climate Experiment (GRACE) has ended operations after 15 years, three times longer than expected. Its mission: Precisely measure Earth's gravitational field from a pair of satellites. Both satellites were needed for GRACE to perform its mission, so when yet another of GRACE-2's batteries failed and contact was lost in September, the writing seemed to be on the wall. The mission team worked heroically to bring it...

    Space Age, scientists have understood how beyond Earth’s magnetic field, space is permeated by radiation. This includes Galactic Cosmic Rays (GCRs), Solar Particle Events (SPEs) ... NASA is able to protect crews from SPEs by advising them to seek shelter in more heavily shielded areas of the station... GCRs are more of a challenge. These energetic particles, which are primarily composed of high-energy protons and atomic nuclei, can come from anywhere within our galaxy and are capable of penetrating even metal. To make matters worse, when these particles cut through material, they generate a cascade reaction of particles, sending neutrons,...

    If the first-in-a-quarter-century meeting last week of the National Space Council was indeed President Trump’s effort to ramp up our national space program and provide benefits for all, then good.But if it is as some perceived – a gauzy send-up to resume the practice of shoveling taxpayer dollars to Washington’s official Friends of the Industry – then we should have no part of it.David von Drehle of the Washington Post took the low road because the Trump administration is involved, calling the commercial prospects for humans “a distraction” and “all pie in the sky.”But in addition to hundreds of thousands...

    One of the techniques currently under development that it is following is NMN, a compound expected to enter clinical trials after it was shown to rejuvenate elderly mice in laboratory tests. It is also considering making more advanced tweaks or alterations to the DNA of its astronauts, although the moral implications of such a radical step will need to be addressed. This includes epigenetic modifications, which alter the way genes are read by the body without making changes to the underlying DNA code. Using such a technique would allow Nasa's scientists to turn up the volume on one genetic instruction...

    Climate Change. Officials from the former Obama White House are starting to speak out against the corrupt administration now that it is safe to come forward. It’s about time! The most recent official to come forward is Steven Koonin, the former Undersecretary of the Department of Energy. He is accusing President Obama of fabricating scientific evidence proving “climate change”. “What you saw coming out of the press releases about climate data, climate analysis, was, I’d say, misleading, sometimes just wrong,” Koonin told the Wall Street Journal. According to Koonin, multiple departments responsible for environmental science either misrepresented data or completely...

    The crew of four men and two women were quarantined on a vast plain below the summit of the world’s largest active volcano in January. All of their communications with the outside world were subjected to a 20-minute delay — the time it takes for signals to get from Mars to Earth. They are part of a study designed to better understand the psychological impacts that a long-term manned mission to space would have on astronauts. The data they gathered will help NASA better pick crews that have certain traits and a better chance of doing well during a two-to-three...

    Amid a summertime swarm of hundreds of earthquakes underneath Yellowstone National Park, NASA is developing a plan to tame a “supervolcano” that some experts believe is well overdue for a catastrophic eruption. The scientists’ plan: cool down the volcano. Volcanoes erupt when a certain heat threshold is built up within the magma, meaning that if enough heat can be let out of the volcano, it will never erupt. NASA’s idea is to pump water into the volcano after opening up a path via drilling. In theory, the plan would extract heat from the volcano and could even provide a new...

Amid a summertime swarm of hundreds of earthquakes underneath Yellowstone National Park, NASA is developing a plan to tame a “super-volcano” that some experts believe is well overdue for a catastrophic eruption. The scientists’ plan: cool down the volcano . . . Brian Wilcox of NASA’s Jet Propulsion Laboratory at the California Institute of Technology told the BBC an attempt to drill from the top of the magma chamber could accidentally cause the very thing the drilling was designed to prevent. To avoid that risk, he suggested drilling from outside the borders of Yellowstone and coming into the...

    The next head of NASA is likely to be an ex-Navy fighter pilot turned Republican congressman who believes strongly in space exploration but is skeptical about man-made climate change. What’s not to like about about Trump’s nomination of Rep. Jim Bridenstine (R-Oklahoma) for the job of NASA’s administrator? Everything, if you’re a liberal. According to New York Daily News columnist Linda Stasi, Trump just blew the perfect chance to change his “presidency from the chaotic mess of threats, bitterness and bilious paranoia to one of rationality and reasonableness.” Apparently, the job should have gone to a fully-fledged climate alarmist.
