    Science fiction space movies can do a poor job of educating people about space. In the movies, hot-shot pilots direct their dueling space ships through space as if they’re flying through an atmosphere. They bank and turn and perform loops and rolls, maybe throw in a quick Immelman, as if they’re subject to Earth’s gravity. Is that realistic?No.In reality, a space battle is likely to look much different. With an increasing presence in space, and the potential for future conflict, is it time to think about what an actual space battle would look like? The non-profit Aerospace Corporation thinks...

    The window for the final round of testing of Virgin Galactic’s rocket-powered spacecraft opens later this week as the company inches toward commercial flights. Virgin Galactic President Mike Moses updated New Mexico lawmakers on the progress during a meeting Monday. He said the space tourism company already has done nine flights from Spaceport America in southern New Mexico, including two glide flights by the spaceship. While the exact date has yet to be determined, the upcoming test will mark the third space flight for Virgin Galactic and the first from New Mexico. Moses called it a big milestone for an...
  • Spacecraft design could get to Titan in only 2 years using a direct fusion drive

    Fusion power is the technology that is 30 years away, and always will be, according to skeptics, at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The concept fusion drive, called a direct fusion drive (or DFD), is in development at the Princeton Plasma Physics Laboratory (PPPL). Though still under development, the engine itself exploits many of the advantages of aneutronic fusion, most notably an extremely high power-to-weight ratio. The fuel for a DFD drive can vary slightly in mass and contains...

    Crew members aboard the International Space Station are dealing with a failed oxygen supply generator located within a Russian module. Thankfully, the astronauts and cosmonauts are not in danger, but this is now the second recent glitch involving a Russian component, which might be cause for concern. The malfunctioning oxygen supply system is located within the Russian Zvezda module and it conked out late yesterday, reports AFP. Sounds scary, but a second oxygen supply system located on the U.S. side is functioning normally and providing breathable air for the ISS crew. Moreover, extra oxygen supplies are stored on the ISS...

Also known as the Sea of Cold, it stretches across the familiar lunar nearside in this close up of the waxing gibbous Moon's north polar region. Dark-floored, 95 kilometer wide crater Plato is just left of the center. Sunlit peaks of the lunar Alps (Montes Alpes) are highlighted below and right of Plato, between the more southern Mare Imbrium (Sea of Rains) and Mare Frigoris. The prominent straight feature cutting through the mountains is the lunar Alpine Valley (Vallis Alpes). Joining the Mare Imbrium...

    While we often discuss expansion into the Solar System as a step leading to interstellar flight, the movement into space has its dark side, as author Daniel Deudney argues in a new book. As Kenneth Roy points out in the review that follows, it behooves everyone involved in space studies to understand what the counter-arguments are. Ken is a newly retired professional engineer who is currently living amidst, as he puts it, “the relics of the Manhattan Project in Oak Ridge, Tennessee.” His professional career involved working for various Department of Energy (DOE) contractors in the fields of fire protection...
  • 5 NASA spacecraft that are leaving our solar system for good

    Most of these interstellar spacecraft carry messages intended to introduce ourselves to any aliens that find them along the way. In 1972, NASA hadn't even finished sending Apollo astronauts to the Moon yet when it started launching the first missions that would ultimately wind up in interstellar space. That wasn't the end goal though. Pioneer 10 and 11 were primarily intended to do humanity's first major reconnaisance of other planets in our solar system. Pioneer 10 achieved the first flyby of Mars, the first trip through the asteroid belt, and the first flyby of Jupiter. And the secret to its...

    NASA chief Jim Bridenstine told lawmakers Wednesday it was crucial for the US to maintain a presence in Earth's orbit after the International Space Station is decommissioned so that China does not gain a strategic advantage. The first parts of the ISS were launched in 1998 and it has been continuously lived in since 2000. The station, which serves as a space science lab and is a partnership between the US, Russia, Japan, Europe and Canada, is currently expected to be operated until 2030. "I'll tell you one thing that has me very concerned—and that is that a day is...

    This August 2020 photo provided by Dr. Se-Jin Lee shows a normal mouse and a "twice-muscled" mouse developed at the The Jackson Laboratory of the University of Connecticut School of Medicine in Farmington, Conn. Findings published on Monday, Sept. 7, 2020, show that muscle-bound mice, similar to the one pictured, held on to their bodybuilder-type physiques during a one month space mission. Bulked-up, mutant "mighty mice" held onto their muscle during a monthlong stay at the International Space Station, returning to Earth with ripped bodybuilder physiques, scientists reported Monday. The findings hold promise for preventing muscle and bone loss...

    Science Alert ^ | 3 SEPTEMBER 2020 | Suzie Neilson
    Officials first noticed a leak last September, but they didn't do anything about it for nearly a year, since the leak wasn't major. Plus, station operations like space walks and crew exchanges kept crew members too busy to collect enough data about the issue. Recently, however, technicians detected an increase to the already elevated leak rate. So NASA announced on August 20 that the three men aboard the station – NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner – would begin a hunt for the source. That search is "taking longer than expected," NASA spokesman Daniel...
  • Another "Oumuamua" Plot Twist: Leading Explanation For Interstellar Object Is Aliens Again

    Last year, an extraordinary thing happened: for the first time in recorded history, astronomers and astrophysicists observed an interstellar object enter and leave our solar system. Over the years, they’ve documented plenty of comets, asteroids, and other cosmic bodies but all have been gravitationally bound to an orbit within our star system. This object, named ‘Oumuamua, came from outside our system, from a star or molecular cloud tens or even hundreds of millions of light-years away, and then left.

    Deinococcus radiodurans is an extremophile microbe capable of surviving freezing cold temperatures, ionizing radiation, ultraviolet light, and dehydration. And as new research published today in Frontiers in Microbiology shows, this bacterium can also survive the harsh conditions of outer space. Dried out samples of Deinococcus were brought back to life after spending over three years on a panel outside the International Space Station. Back in 2008, Yamagishi and his colleagues used aircraft and balloons to detect and document microbes floating in the upper atmosphere. Naturally, samples of Deinococcus radiodurans—a microbe Guinness World Records lists as the most radiation-resistant lifeform—were found...

    Elon Musk has become the fourth-richest person in the world, amassing a fortune worth nearly $85 billion. The mark was crossed on Monday after shares of Tesla Inc. surged more than 11%, boosting the affable tech exec's net worth by nearly $8 billion, according to Bloomberg. At a net worth of $84.8 billion, Musk trails only Facebook CEO Mark Zuckerberg, Microsoft co-founder Bill Gates and Amazon CEO Jeff Bezos on Bloomberg's Billionaires Index. Much of Musk's net worth is tied up in his electric car maker Tesla, which has seen its shares surge more than 300% this year. The car...

    Distant cosmic objects such as planets, galaxies, and nebulae are sometimes referred to by the scientific community with unofficial nicknames. As the scientific community works to identify and address systemic discrimination and inequality in all aspects of the field, it has become clear that certain cosmic nicknames are not only insensitive, but can be actively harmful. NASA is examining its use of unofficial terminology for cosmic objects as part of its commitment to diversity, equity, and inclusion. As an initial step, NASA will no longer refer to planetary nebula NGC 2392, the glowing remains of a Sun-like star that is...

    "One small step for a man, one giant leap for mankind," stated Astronaut Neil Armstrong, JULY 20, 1969, as he became the f irst man to walk on the moon, almost 238,900 miles away from the Earth. The second man on the moon was Colonel Buzz Aldrin, who described it as "magnificent desolation." Aldrin earned a Ph.D. from M.I.T. and helped develop the technology necessary for the mission, especially the complicated lunar module rendezvous with the command module. Buzz Aldrin's popularity was the inspiration for the character "Buzz Lightyear" in Pixar's animated movie Toy Story (1995). Buzz Aldrin shared a...

    Two Indian schoolgirls have discovered an asteroid which is slowly shifting its orbit and moving toward Earth. Radhika Lakhani and Vaidehi Vekariya, both studying in 10th grade, were working on a school project when they discovered the asteroid, which they named HLV2514. The girls, from the city of Surat in the western Indian state of Gujarat, were participating in a Space India and NASA project, which allows students to analyze images taken by a telescope positioned at the University of Hawaii. Aakash Dwivedi, senior educator and astronomer at Space India, told CNN that students across India were taught how to...

    NASA’s Mars 2020 Perseverance Rover has launched on its epic mission to the Red Planet. The rover launched into space atop a United Launch Alliance Atlas V rocket at 7:50 a.m. EDT from Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The Rover lifted off right at the start of the mission’s launch window, which had been planned for when Earth and Mars are in perfect alignment. Lifted by 2 million pounds of thrust, it took the rocket about 5 seconds to clear the launch tower at Cape Canaveral. "We're in touch with the spacecraft, everything is...
