Rosetta comet mission falls into trouble
...
Ecstasy turned into worry when it emerged that the lander, which was supposed to use harpoons to tether itself to the comet's surface, was unable to fire them and appeared to be moving around, a Daily Mail report said.

Stephan Ulamec, who ran the landing programme, said early tests suggested that the craft had bounced before turning and settling again.

“It touched down and was re-bouncing. So maybe today, we didn't just land, we landed twice,” he was quoted as saying.

Ulamec added that scientists were still not sure about the status of the project.

Seashore Weather Update - сеуште нема ir-фотки

http://blogs.esa.int/rosetta/2014/11/14/rosetta-mission-results-from-comet-landing-14-nov-1300-gmt/

14.11.2014 - European probe plants thermometer on comet

The European Space Agency says its Philae lander is doing well and has succeeded in planting a thermometer in the comet where it touched down this week.
The agency said Friday that scientists have received a steady stream of data from the lander, which on Wednesday became the first spacecraft to touch down on a comet. However, their job is complicated by the fact that Philae landed next to a cliff that is blocking sunlight from its solar panels.
Planting a thermometer in the surface was Philae's first so-called "mechanical operation" but ESA says it will hold off on any more for now. The lander's primary battery only has power for another day or so and scientists are contemplating realigning it so that the solar panels can charge the craft [1]

    за греота

    се прашувам дали се волку вицкасти и кинезите

    Danger: What should astronauts avoid doing?

    Do you want the funny answer or the serious answer? Not sure...? Well let me give you a little of both!

    There are obvious things an astronaut shouldn't do. For example, you shouldn't put your spacewalking boots on the wrong feet. Also, you should not forget to attach your safety tether to the tether point immediately outside the hatch before exiting said hatch on your spacewalk. You should not --upon receiving coupons for a lifetime's worth of free pizza at a speaking appearance-- toss the coupons out into your audience, creating a mass "feeding frenzy" that may ultimately put the owner of the pizzeria out of business when numerous patrons show up at the same time for free pies.

    ~

    Many of you may now be thinking... okay, enough with the jokes, tell us some real stuff. Well, according to my "sources" (and they are pretty darned reliable), everything I listed above is TRUE...

    ~

    In short, as an astronaut you must realize that everyone is watching you; all the time. Always follow the mantra of "... keep your head down and keep coloring." Yet eventually, we're all going to gooch up something and as an astronaut it's hard to know when and if your actions will carry severe --or no-- consequences. The so-called "bar" is a variable; set high for some, and quite low for others. In reading Canadian Astronaut Col. Chris Hadfield's Book, "An Astronaut's Guide to Life on Earth," he related ways he thought being an astronaut provided life lessons for those not in the profession. He didn't tell you about this one. It exists in every walk of life.

    Still, being an astronaut... I wouldn't trade a second. It's the greatest job in the universe!

    19.11.2007 - Руси на Марс пред Американците

    Рускиот вселенски брод со човечки екипаж би можел да слета на Марс веќе во 2025 година, или десетина години пред Американците.

    Трошоците на руската вселенска експедиција, според најновите процени на експертите, ќе бидат околу 100 милијарди долари, што е петпати помалку од цената на истиот проект на НАСА.

    Руската агенција за космички истражувања (РОСКОСМОС) и НАСА претходно ја утврдиле 2035 година како рамковен рок за праќање вселенски брод со човечки екипаж на Марс.

    Руските експерти сметаат дека нивната земја има предност во понатамошната реализација на тој меѓупланетарен проект.

    18 Feb 2016 - ‘Jump in knowledge’: EU & Russia space teams merge for ExoMars - https://www.rt.com/news/332929-exomars-drill-mission-pischel/

    17 Jan 2016 -  Institut iz Srbije pravi letjelicu za misiju na Jupiter 

    Institut Biosens iz Novog Sada ima sve više patenata i sve više zaposlenih naučnika, a svemirske tehnologije samo su dio inovacija te firme.

    Mala budžetska izdvajanja i nedostatak sredstava najčešće su zamjerke naučnika u Srbiji, ali situacija je znatno drugačija u jednom novosadskom naučnom centru.

    Institut Biosens ima sve više patenata i sve više zaposlenih naučnika.

    Evropska svemirska agencija uveliko priprema misiju na Jupiter, ali zbog ekstremnih temperatura i radijacije, izazov je napraviti letjelicu koja će godinama raditi bez oštećenja.

    Dio tog posla povjeren je i naučnicima Biosensa iz Srbije, koji su osmislili novu vrstu metala koji će služiti kao motor za pokretanje dijelova buduće letjelice.

    “To radi kao motor bez ikakvih pokretnih dijelova, može da se zgužva. Evo ga, ja sam ga zgužvao, baciću ga u vodu, on se sam popravi ispravi“, kaže istraživač Jovan Matović.

    Svemirske tehnologije samo su dio inovacija instituta Biosens. Najveći broj patenata usmjeren je ka primjeni IT tehnologija u poljoprivredi. Jedan uređaj dovoljno je okrenuti u pravcu biljke, a za nekoliko sekundi na ekranu se ispisuju sva njena svojstva.

    U kombinaciji sa satelitskim snimcima, poljoprivrednici dobijaju precizan uvid u stanje i potrebe svojih zasada.

    Antares rocket producer orders 8 more Russian engines - https://www.rt.com/usa/334994-russian-engines-antares-rocket/

    https://www.rt.com/news/223383-rd181-antares-rocket-engine/

    Gross Mismanagement of American Rocket Science Beginning to Show?

    The fact that so many U.S. launch programs have resorted to Russian engine technology is a giant red flag in an aerospace industry struggling to shrug off recent failures, political setbacks and accusations about the premature retirement of the Space Shuttle Program. The loss of the Shuttle, in particular, has forced the U.S. to bear the humiliation of being dependent on Russian launch vehicles for rides to the Space Station at a geopolitically hostile time.

    The headline’s suggestion that Russian sales girls are responsible for these problems is tongue-in-cheek, of course, though vodka might have been a factor. I (the author) have worked on the Atlas V program alongside Russian rocket engineers, and I greatly admired their professionalism and skill. They are geniuses, every one. But aside from that, I don’t know how to explain the strategically inexcusable decisions that have made U.S. access to space totally dependent on Russian cooperation. This seemed a mistake when the first moves were being made in the 1990s, and it seems the full weight of those mistakes are becoming clear now. The U.S. is simply unprepared to supply all the affordable, dependable rocket engines it now needs, and that is due to catastrophic mismanagement and a drought of foresight. Fixing that will take some time. [1]

    Maybe it’s not surprising that in those early days, Nike crossed paths with NASA; at that time, just about every new invention seemed to trace itself back to the Apollo missions somehow. Nike Air was no exception.

    ...

    in 1978, Nike revealed the next big thing:  

    First produced for the Honolulu Marathon, the Nike Air Tailwind included new technology developed by former NASA engineer M. Frank Rudy. Rudy’s innovation repurposed an aeronautics technique called blow rubber molding. It was once used to create astronaut helmets for the Apollo missions and later enabled Rudy to design a hollowed-out midsole in which he embedded polyurethane pouches filled with dense gases.

    The idea—as well as the branding strategy—hinged upon the assumption that running on air would provide superior cushioning, since the sacks of gas wouldn’t wear out after repeated use. Nike Air was initially marketed to elite runners, though that strategy shifted over time to include anyone with $100 or more to spend on sneakers.

    Move over Nasa: Russia reveals plans for 2018 test of nuclear engine that could get cosmonauts to Mars in SIX WEEKS
  • This compares to 18 months spacecraft currently need to get to Mars

  • Nuclear propulsion weighs almost half as much as a chemical rocket

  • Nasa is also are planning to build rockets powered by nuclear fission

  • They hope it could be used to carry astronauts to the red planet in 2033

  • Russia has announced that it will test a nuclear engine in 2018 that could help cosmonauts reach Mars in just six weeks.
    This compares to the 18 months spacecraft currently need to get to Mars, and could make Russia the first nation to land humans on the red planet.
    The country is betting on nuclear propulsion because it weighs almost half as much as a chemical rocket without reducing thrust.

    This means larger payloads of cargo can be carried on the spacecraft and they can also be made to travel far faster.
    And unlike existing technology which uses defined trajectories, a nuclear engine also allows a spacecraft to manoeuvre throughout the flight.
    The $274 million project, which was originally overseen by the space agency RosCosmos in 2010, has now become the responsibility of nuclear group, Rosatom.
    'A nuclear power unit makes it possible to reach Mars in a matter of one to one and a half months, providing capability for manoeuvring and acceleration,' Sergey Kirienko, head of Rosatom told RT .
    'Today's engines can only reach Mars in a year and a half, without the possibility of return.'
    Russia currently has used over 30 fission reactors in space, the US has flown only one - the SNAP-10A (System for Nuclear Auxiliary Power) in 1965.
    HOW NUCLEAR PROPULSION WORKS
    Nuclear rockets are rocket engines that use a nuclear fission reactor to heat propellant.

    Fission entails the splitting of atoms of uranium in a nuclear reactor

    The idea is relatively simple; a nuclear reactor will be used, similar to the ones used for power generation today.

    However, rather than using the reactor to heat water into steam, it will heat propellant instead and run it out of a rocket nozzle for thrust.

    Engineers at Nasa have also been drawing up plans to use nuclear thermal propulsion in a mission to Mars in 2033.
    According to the space agency's design, uranium-235 nuclear reactions are used to heat liquid hydrogen inside a reactor, turning it into ionized hydrogen gas, or plasma.
    This plasma is then channeled through a rocket nozzle to generate thrust.









    Dr Stanely Borowski, an engineer at Nasa's John Glenn Research Centre, last year outlined how this could then be used to propel a space with its crew through space in a official Nasa paper.
    He said the spacecraft, called Copernicus, would consist of separate cargo and crewed transfer vehicles, each powered by a nuclear thermal propuslion stage.
    These would be constructed from a 'core' that use three engines each capable of producing thrust of around 25,000 lbs of force.
    He estimates that these vehicles could make the 40 million mile trip to Mars within 100 days.
    It took the Mars Science Laboratory spacecraft carrying Nasa's Curiosity Rover to Mars 253 days to reach the red planet.
    Writing in his paper, Dr Borowski said: 'The analysis presented here indicates transit time reductions as much as 50 per cent are possible.'
    Nasa first began researching nuclear thermal rockets as part of its Nuclear Engine for Rocket Vehicle Application (NERVA) programme in 1959.

    However, the project, which was a collaboration between Nasa and the US Atomic Energy Comission, was officially ended in 1973.
    During that time, engineers produced several prototypes, the most advanced of which was known as a Pewee engine. None of the engines were ever used for flight.
    Proposals to use nuclear powered rockets were also discussed in a presentation last year by Dr Michael Houts, nuclear research manager at Nasa's Marshall Space Flight Centre.
    He described the nuclear propulsion was a 'game changing technology for space exploration'.
    He said they hoped to prove the viability and affordability of the technology within the next three years.
    Dr Houts said: 'Nuclear thermal propulsion is a fundamentally new capability - the energy comes from fission not chemical reactions.
    'Advanced nuclear propulsion systems could have extremely high performance and unique capabilities.'
    ASA'S NUCLEAR HISTORY

    Nasa has been using nuclear material to power spacecraft for decades.

    In 1960 a satellite programme called TRANSIT, used to guide missiles from space, was the first to use plutonium isotopes to create batteries.

    These work by wrapping the plutonium with thermoelectrics, that turn the heat given off by the decaying isotope into electricity.
    Nasa also used plutonium batteries on its failed Nimbus B1 satellite, which blew up on launch.

    In 1972 and 1973 Nasa then launched its Pioneer space probes, which used 155-watt nuclear batteries to keep them powered as they travelled to the very edge of the solar system.

    The Viking landers, which touched down on Mars for the first time in 1976, also used plutonium batteries to power their experiments.

    The Voyager probes, which have become the first manmade objects to leave the solar system, also relied upon three plutonium-238 batteries that have allowed them to communicate with Earth for 36 years.

    The Ulysses sun probe also used a nuclear battery to keep the spacecraft operating while it performed a slingshot around Jupiter.

    The Galileo spaceprobe to Jupiter's moons also used two nuclear batteries to give it 570 watts of power.

    The Cassini space probe to Saturn carried the largest nuclear battery every launched, weighing 72lbs.

    In 1959, Nasa began work with the US Atomic Energy Commission to develop a nuclear powered rocket to carry astronauts into space, but the project was ended in 1973 at the same time as the Apollo space missions.

    06.08.2016 - Во Русија проработи првиот систем за контрола на вселенскиот простор

    Првиот од четирите планирани системи за контрола на вселенскиот простор почна со работа во Алтајскиот крај во оптичко-ласерскиот центар „Титов". Ова го изјави генералниот генералниот директор на научно-производствената корпорација „Системи за производство на прецизни прибори“ Јуриј Рој, пренесува „Взгљад“ во саботата, 6 август.

    Татковината на шпионските сателити

    „Останатите три системи ќе бидат распоредени во Калининград, на Далечниот Исток и на Крим. Системот на Алтај е управуван заеднички од воен и цивилен персонал. Создаден е да открива вселенски апарати, наносателити, вселенски отпад – сѐ што може да ги загрози вселенските летала и, особено, Меѓународната вселенска станица“, објасни Рој.

    Новиот систем е пуштен во работа по повод 55 години од летот на вториот космонаут на планетата Герман Титов.

    SpaceX successfully launches and lands a used rocket for the second time

    The seventh at sea, and the 12th successful landing overall

    by Sean O'Kane@sokane1 

    SpaceX has successfully launched and landed a recycled Falcon 9 rocket for the second time. The rocket’s first stage — the 14-story-tall core that houses the fuel and the rocket’s main engines — touched down on one of the company’s autonomous drone ships in the Atlantic Ocean shortly after taking off from a launchpad at nearby Cape Canaveral, Florida. It’s the 12th time SpaceX has successfully landed one of these rocket stages out of 17 attempts, and the seventh time it’s performed the feat at sea.

    This particular rocket previously flew in January, when it was used to put 10 satellites into orbit for communications company Iridium. The rocket then landed on a drone ship in the Pacific Ocean. SpaceX retrieved the rocket and spent the next few months refurbishing it in preparation for today’s launch. This afternoon, it was used to launch Bulgaria’s first communications satellite for TV service provider Bulsatcom.

    The landing wasn’t easy, though. Because the rocket had to push BulgariaSat-1 to such a high orbit, the first stage experienced more force and heat during reentry than any other Falcon 9, according to a tweet from SpaceX CEO Elon Musk. Musk even warned that there was a “good chance [the] rocket booster doesn't make it back.”

    Shortly after the landing, though, Musk returned to Twitter to add that the rocket booster used “almost all of the emergency crush core,” which helps soften the landing. It was the first time SpaceX has landed one rocket on both of its drone ships. (SpaceX keeps one in California for launches from Vandenberg Air Force Base.)

    Rocket is extra toasty and hit the deck hard (used almost all of the emergency crush core), but otherwise good

    Being able to reuse parts of the Falcon 9 rocket has long been a goal for Musk. He’s been trying to get the company to a point where it can reuse things like the rocket’s main stage, or the payload fairing (the cone at the top), instead of building a new rocket for each new launch. Reusing rockets is a great way to bring down launch costs; previously, they were discarded after each launch, and building them from scratch costs millions of dollars.

    To that end, SpaceX launched and landed a reused Falcon 9 for the first time back in March, and it also recovered that rocket’s fairing — a first for the company. Then, earlier this month, SpaceX sent a used Dragon cargo capsule back to space for the first time ever.

    But it’s the company’s strides towards sticking these rocket landings that finally made this all possible. While many of its early landing attempts were met with fiery ends, SpaceX hasn’t lost a rocket in a landing attempt since early last summer. With today’s success, the company has now landed eight rockets in a row dating back to that June explosion, save for a few launches where there wasn’t enough leftover fuel for a landing attempt.
