NASA's laser-powered spacecraft will fly to Mars in 72 hours - Mars exploration compilation

Domino's presents the path to Mars NASA postpones Flying Saucer test due to wins in Hawaii NASA was forced to cancel six attempted launches of a saucer-shaped Mars landing test vehicle in early June because of unusually strong winds at the hawaiian test site landing heavier spacecraft on Mars presents a challenge as Mars's atmosphere is around 100 times thinner than Earth meaning that it cannot provide sufficient resistance to slow down a spacecraft first safe landing to combat the problem nASA has developed a low density supersonic decelerator a 3048 kilogram flight vehicle which has the potential to overcome the obstacles of a Martian landing the first step of the test requires launching the vehicle using a helium balloon which will take the lander up to an altitude of 36,000 600 meters the balloon will then detach from the craft which could continue its ascent by igniting solid fuel engines when the vehicle reaches 50 4800 meters it will be traveling at a maximum speed of Mach 4 as it slows down from mark 4 to mark 3.8 it will deploy a device called a supersonic inflatable aerodynamic decelerator which looks like an inflatable hula-hoop to further reduce its speed from mark 3.8 to lap 2.5 a parachute will then be deployed to further reduce the flight vehicles velocity on its journey back to earth the vehicle will then be recovered from the Pacific Ocean off Hawaii the test is now rescheduled for late June NASA's laser powered spacecraft aims to reach Mars in 72 hours NASA scientist Phillip Lubin is working on perfecting laser technology that could propel a light spacecraft to Mars in as little as three days photons emitted from excited atoms in a laser have energy and momentum which forms the basis of laser based propulsion photons are released in a beam from a laser when photons from a laser array reflect off an object their energy is translated into a push that's capable of moving objects like a spacecraft rather than using a giant laser all of the Death Star's researchers imagine an array made up of a large number of amplifiers that sync up and act like one big laser the spacecraft launched with this technology will include a robotic probe and a large reflective sail the spacecraft will be light because no fuel is needed and this base craft could be accelerated to 30% the speed of light which was previously unheard of this technology could produce enough momentum to get a robotic spacecraft to Mars in three days and send a man shuttle to Mars in a month using photonic propulsion interstellar travel may be possible and we could get a probe to Earth's nearest star Alpha Centauri in as little as 15 years in comparison our current technology takes four to eight months to get to Mars it took 37 years for the Voyager 1 spacecraft to reach the edge of our solar system NASA developing inflatable heat shield that could be used for manned missions to Mars NASA is developing an inflatable heat shield that could one day be used to send astronauts to Mars designed by NASA's Langley Research Center the inflatable shield could help overcome the difficulties of landing on the red planet where the atmosphere is too thin for modern rockets or parachutes to safely land large spacecraft the heat shield was inspired by the idea of a stacking ring of toy donuts inside the heat shield our inflatable segments covered in thermal blankets upon entering the Martian atmosphere the Rings would be inflated with nitrogen and the heat shield would slow the descent of the spacecraft in an atmosphere that is 100 times thinner than that of the Earth's NASA plans to test the technology on the next flight of the Antares rocket in 2016 because the heat shield is inflatable and lightweight it would free up more room inside a spacecraft it could also allow for spacecraft large enough to carry humans to land safely on Mars unlike current heat shields which can only land rover's the same inflatable technology could also one day be used to help spacecraft land on other planets and moons in the solar system like Venus and Titan NASA funded scientists a fusion rocket engines could take a manned crew to Mars in 30 to 90 days the fusion rocket pulses at a rate of one blast for minute causing exhaust to exit the divergent magnetic nozzle at 30 km/s solar energy will provide electricity needed to charge the capacitors which then power the fusion rockets magnets for each pulse of the rocket engine powerful magnets crush a series of lithium metal rings around a ball of tritium deuterium plasma an exothermic reaction occurs providing thrust the fusion rocket engine will only be active for 10% of the voyage half of the time to speed away from the Earth and the other half to slow down upon arrival near Mars unlike a conventional chemical rocket the fusion Rockets lithium fuel takes up only 50% of its mass compared to 98% for a liquid fuel Saturn 5 rocket the fusion rocket should also be more cost effective than a chemical rocket whose primary cost was transporting fuel to space space works believes the key to space travel may be artificially induced sleep a NASA funded study written by aerospace engineering company Space Works says that keeping astronauts unconscious during long flights in space cuts down the equipment and resources needed on the shuttle and also eliminates the negative psychological effects of long hauls in space according to the NASA funded study on cryogenic sleep a human body can be placed in hibernation by simply lowering the body temperature to 93 degrees Fahrenheit the lowered body temperature causes the body's heart rate and metabolism to decrease the body will subsist on intravenous feeding tubes that pump the necessary nutrients into the body other tubes will drain urine as well as monitor the body according to mock ups a torpor status habitat can hold six astronauts at once in robotic arms will ensure everyone's basic needs are met so far humans are only able to maintain stasis for 14 days although the trip from Earth to Mars is expected to take up to nine months or about 274 days nASA has declined to fund the second stage of the research though in space work citing as potential therapeutic benefits is now looking into using the technology here on earth US Space Agency NASA will have to find creative solutions to overcoming the hazards of space radiation for future manned missions to Mars radiation readings from the Curiosity rover on route 2 and while on Mars revealed levels dangerous to humans exposure to solar radiation would be highest during the 182 253 day journey to the Red Planet current spacecraft radiation shielding is insufficient for such long journeys walls filled with hydrogen rich water offer one solution electromagnetic shields could provide even more protection astronauts would need this protection to survive the mission an average CT scan gives a dose of around 10 millisieverts whereas a round trip to Mars would expose a human to 554 to 770 millisieverts of radiation excessive exposure to radiation can cause cataracts cancer of the thyroid glands lungs stomach and sterility NASA aims to send you Touma's sometime in the 2030s NASA prepares to roll out Orion spacecraft NASA is entering the final stages of preparation for testing its new Orion spacecraft the US Space Agency NASA launched space shuttles 134 times from 1981 to 2011 but budget cause forced the program's retirement but NASA says it's almost ready to launch a new space vehicle one that borrows extensively from the Apollo program that sent humans to the moon in 1969 the new Orion spacecraft will have a range of updated features for 21st century space exploration and is capable of remaining in space for about six months the Orion will also be roomier with a larger crew and service module the launch escape system has also been updated in the event of trouble on the launch pad or during launch a smaller rocket will propell the crew module away from the main rocket deploy parachutes and land safely NASA plans a late 2014 test of the entire system that will see Orion fly 15 times farther into space than the International Space Station before returning to Earth at speeds of more than 30,000 km/h and splashing down in the Pacific Ocean with the Orion NASA is taking a Back to the Future approach by updating technologies that are decades old but have proven themselves to be cost-effective and reliable NASA descender Ryan spacecraft on unmanned flight tests the Orion spacecraft which is designed to carry astronauts to Mars will undergo an unmanned flight test in early December an Orien capsule will be launched into space on a delta 4 rocket from Cape Canaveral on December 4th the lower stage and the launch abort system will separate from the upper stage Orion will orbit twice around the earth when it reaches an altitude of 5800 kilometers it will be 15 times higher above the planet than the International Space Station Orion's upper-stage will then separate and its crew module will return to earth its heat shield is designed to ensure it will be able to withstand temperatures of almost 4,000 degrees Fahrenheit during reentry when the spacecraft returns to the atmosphere parachutes will deploy in different stages to slow its descent scientists will retrieve the capsule after it falls into the ocean nASA has allocated 375 million dollars for the first test flight and subsequent tests the Orion will be mounted on a new rocket named a Space Launch System NASA's Orion spacecraft prepares her first test launch the capsule that will bring cam is one step closer to setting foot on Mars is slated to make his first flight in 2018 five months ago NASA technicians began the first assembly weld on the Orion multi-purpose crew vehicle or MPCV spacecraft the Orion's pressure vessel the part filled with air for astronauts started out in seven pieces those pieces were fused together by mid-january the pressure vessel was then transported from the Michoud assembly facility in Louisiana to the Kennedy Space Center in Florida it traveled on a super guppy cargo aircraft equipped with a compartment that is 25 feet tall 25 feet wide and 111 feet long and it arrived on February 1st at the Kennedy Space Center the Orion will be equipped with subsistence outer layers and a heat shield everything it needs to complete is fresh mission which nASA has announced will be an unmanned test flight to the moon and 2018 to check a structural integrity the little guys already being Harold America's next great leap in space exploration that's a lot of pressure for your first assignment but you got this Orion NASA confirms existence of liquid water flowing on Mars nASA has confirmed that there is liquid water flowing on Mars which is a potential breakthrough in the quest to search for life beyond Earth according to NASA scientists liquid water runs down canyons and crater walls on Mars leaving dark stains in the terrain these stains known as the recurring slope lineae or RSL occur when temperatures rise above minus 10 degrees Fahrenheit the stains disappear during the cold season scientists discovered perchlorate salts on Mars's surface by looking at infrared light waves reflected from the RSL the salt is crucial in keeping water in liquid form by lowering the freezing point of water one possible theory of the origin of the flow of water is deliquescent a process where salt absorbs water from the air it remains to be seen whether this discovery will prove the life exists on Mars NASA researchers will now focus on where the water comes from the Curiosity rover sends back photos showing evidence that there may have been a lake on Mars NASA's Curiosity rover has sent home photos showing evidence of water currents and sediments on Mars nASA says this implies the planet may have maintained a climate that could have produced long lasting lakes NASA's Curiosity rover has been taking photos of the lowest sedimentary layers at Mount sharp a section of rock 500 feet tall inside the 96 mile wide Gale Crater the photo shows signs of water currents and sediments on rocks inside the crater nASA says this implies Mars may have been able to support long lasting lakes that could have supported microbial life for millions of years scientists speculate that in the ancient past runoff from the crater rim could have created a lake in which sediment gradually settled and built up to form Mount sharp NASA has long speculated that Mars once held water NASA previously theorized that gravel like rocks found on Mars could have been smoothed by water and pushed into the shape of an alluvial fan the longest running Mars rover Opportunity has covered a record-breaking 22 miles as it approached his tenth year on the red planet NASA Mars rover Opportunity launched from Cape Canaveral on July 7th 2003 after traveling 283 million miles through space over seven months opportunity - landed on Mars on January 25th 2004 the rover rolled to a stop in Eagles crater opportunity was designed for a 90-day mission to search for evidence of liquid water that may have supported life-forms on Mars within weeks the rover found mineral crystallization 'he's left behind by the passage of water ten years later opportunity is still collecting data on Mars the rover runs on solar power and uses a panoramic camera for navigation collected data is sent back to earth via low and high gain antennas Opportunity is equipped with a microscopic imager and spectrometer to study Mars's surface geology the rover takes pictures of Mars's terrain and calculates the best route for traversing the planets rocky surface it is endured a sand trap and a sunless dust storm it continues to run on a damaged right front wheel currently Opportunity is heading to sul and a point where tens of metres of geological layering are exposed for analysis in May opportunity broke the u.s. record for the greatest total mileage covered on a surface apart from Earth it is expected to surpass the world record held by the Soviet Luna cod2 lunar rover opportunity's sister rover spirit stopped running on Mars in 2011 NASA's Mars science exploration laboratory rover Curiosity landed on the planet in August 2012 and has since been exploring the Gale Crater area mad scientist Elon Musk once tecnique Mars Stephen Colbert recently compared Elan musk to a real-life Tony Stark during an interview in which the entrepreneur set out his vision to make Mars habitable now how exactly will this mad scientist make this foreign land habitable good old American Way mom's terraforming is the hypothetical process of altering a planet's environment to make it livable Tesla CEO Elon Musk recently floated the idea that Mars could be terraformed through nuclear strikes to destroy its polar ice caps the average temperature on Mars is similar to dark Takai in winter destroying the poles may warm the planet but scientists told the Los Angeles Times this may not warm Mars enough and could lead to unknown changes in its terrain naturally Twitter had something to say user Jim Royce asked can must get any cooler while Jackalope asked why does must wanna nuke Mars another slower method musk suggested would be heating the planet through greenhouse gases but this also faces problems as Mars current levels of carbon dioxide are potentially suitable for plants but poisonous to animals what do you think of Musk's ideas are they science fiction what do you think he may actually have a point the European Space Agency is launching a test run on February 11 of its new reusable spacecraft this mission is unique as ASA's unmanned experimental spaceship will maneuver itself back through Earth's atmosphere the Vega rocket containing ASA's intermediate experimental vehicle or ixv will launch from kourou french guiana on wednesday the rocket will open its two-piece shell at an altitude of 320 kilometers in release to ixv dye XPS 300 sensors will collect various data throughout the spacecraft's 100 minute mission rocket thrusters and flaps will control xbase descent back to earth and that sensors will continue to calculate data throughout the reentry process the spacecraft will deploy parachutes in order to slow itself down before landing balloons released from the side of the spacecraft will keep the XV afloat until it's recovered die X via CSA's first step towards creating reusable spacecrafts that may one day return from missions to Mars or shuttle astronauts back from space stations the Indian Space Research Organization has announced the launch date for its most ambitious project yet the Mars orbiter mission India's mangalyaan satellite has moved from its testing center in Bangalore to Sri Hari Kota on the East Coast where it will launch on October 28th the spacecraft will orbit earth for several weeks before beginning at 10 month 400 million kilometer journey to the Red Planet under its own propulsion when it reaches Mars's orbit the mangalyaan will separate from its rock and deploy its solar panel the satellites elliptical orbit will take it 372 kilometers from Mars at his closest point and 80,000 kilometers at its farthest it's 15 kilogram payload includes a methane sensor to study the evolution of the planet's atmosphere a camera for detailed photographs of the surface and a thermal infrared spectrometer to gather mineral composition data the 83 million dollar Mars orbiter mission is the country's boldest step in the global space race the program's last project five years ago found evidence of water on the moon
