Featured B Space Stuff and Launch Info

  1. Jul 17, 2016 #1
    Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile:

    Moving right along, this is a great write up with a lot of potential.
    As a side note, the first image of the Columbia crew in the article is taken from a piece of digital tape recovered after the crash. This tape has some interesting footage of the reentry, If anyone knows where (website or whatever) this can be viewed could you please let me know, thanks.
    ( the footage is of the reentry plasma flashes not the actual crash)
    Also along with the other experiments on CRS9
    This cool device. http://www.bbc.com/news/science-environment-36824897

    And the K2 mission has had a very good day.:smile:

    This is probably the best quality one... that I have seen.

    Also, click the "SHOW MORE" box for some explanation...

    Excellent, that's the one I was thinking of. It's hard not to get a sense of impending doom as that plays.
    Here is a pretty cool view of the latest ISS crew arrival, this is the roughest docking I have ever watched.

    Thought I'd throw in this one also.

    One down...http://spaceflight101.com/progress-ms-03-links-up-with-iss-for-orbital-cargo-delivery/
    A cool view,
    One to go,
    From https://blogs.nasa.gov/spacestation/2016/07/19/dragon-prepares-for-wednesday-morning-arrival/
    "The International Space Station and SpaceX Dragon flight control teams are proceeding toward
    rendezvous and grapple of the unpiloted Dragon cargo craft Wednesday, July 20, following
    Monday’s launch of the spacecraft atop a Falcon 9 rocket from Cape Canaveral Air Force Sta-
    tion in Florida.

    Capture of Dragon is scheduled at 7 a.m. EDT. Installation of the Dragon to the Earth-facing
    port of the Harmony module will begin several hours later."

    This is some interesting "space & stuff", the theory on the cause is great reading, some fascinating physics going on there.
    from, http://www.nasa.gov/feature/jupiter-s-great-red-spot-likely-a-massive-heat-source
    NASA's Juno spacecraft, which recently arrived at Jupiter, will have several opportunities during its
    20-month mission to observe the Great Red Spot and the turbulent region surrounding it. Juno will
    peer hundreds of miles downward into the atmosphere with its microwave radiometer, which passively
    senses heat coming from within the planet. This capability will enable Juno to reveal the deep
    structure of the Great Red Spot, along with other prominent Jovian features, such as the colorful
    cloud bands.

    The study, in the July 27 issue of the journal Nature, concludes that the storm in the Great Red Spot
    produces two kinds of turbulent energy waves that collide and heat the upper atmosphere. Gravity
    waves are much like how a guitar string moves when plucked, while acoustic waves are compressions
    of the air (sound waves). Heating in the upper atmosphere 500 miles (800 kilometers) above the
    Great Red Spot is thought to be caused by a combination of these two wave types crashing, like
    ocean waves on a beach.

    Here is a bit of an anomaly in the "star formation department". A stellar nursery without the nursery.
    From, http://www.jpl.nasa.gov/news/news.p..._campaign=NASAJPL&utm_content=daily20160727-1

    "When CX330 was last viewed in August 2015, it was still outbursting.
    Astronomers plan to continue studying the object, including with future
    telescopes that could view it in other wavelengths of light."

    "Most puzzling to astronomers, FU Orionis and the rare objects like it -- there
    are only about 10 of them -- are located in star-forming regions. Young stars
    usually form and feed from their surrounding gas and dust-rich regions in
    star-forming clouds. By contrast, the region of star formation closest to CX330
    is over a thousand light-years away."

    Also good news for the ExoMars mission, they are on track for an orbital insertion, October 19th.

    This is very promising, I think the government cooperating with private industries is going to do wonders for advancing science. The "I got mine sorry about yours" mindset is one of the biggest hurdles we face developing in technologies, I'm hoping this trend catches on in an international way.
    "From, https://spaceflightnow.com/2016/07/29/nasa-spells-out-support-for-spacexs-red-dragon-mars-mission/

    Manning said SpaceX has already shared data from their Falcon 9 booster stages, which fire up their
    Merlin engines for a series of re-entry and landing burns. The rocket conducts those maneuvers while
    flying at up to 4,000 mph (6,300 kilometers per hour), depending on each launch’s specific profile.

    We find out that, indeed, it’s possible to do, to fly your engines backwards, and all the mysteries we
    thought about flying your engines backwards have really gone away," Manning said. "One of the things
    we thought is, so what are the dynamics? What is the flow? Is the vehicle going to be batted around by
    this high-speed flow? Well, it turns out that thrusters actually produce a vacuum bubble around the
    vehicle, and it looks terrible on the outside... But it looks great on the inside."

    I hadn't heard of this one, should make a nice companion for JWST
    From, http://www.nasa.gov/feature/goddard/2016/nasas-tess-the-next-exoplanet-explorer
    Among the stars TESS will observe, small bright dwarf stars are ideal for planet identification,
    explained Joshua Pepper, co-chair of the TESS Target Selection Working Group. One of the TESS
    science goals is to find Earth- and super-Earth-sized planets. These are difficult to discover
    because of their small size compared to their host stars, but focusing TESS on smaller stars makes
    finding these small planets much easier. This is because the fraction of the host star's light that a
    planet blocks is proportional to the planet’s size.

    From, http://www.planetary.org/explore/sp...tunity-nears-end-of-marathon-valley-tour.html

    "Along the way, the rover that loves to rove has
    broken robot records and established new
    milestones, including finishing the first marathon
    and becoming the longest-lived robot on another
    planet years after surviving a planet encircling dust
    storm she wasn’t designed to survive. The MER
    ops team in the process has become the tightest,
    most experienced Mars rover team on Earth. And
    now the mission is getting ready to embark on
    what ultimately may be the most exciting
    adventure of all."

    "The rover planners at JPL will drive Opportunity
    down steep, rugged slopes, and over more Martian
    hills and dales to places where geological features
    beckon the scientists, rousing visions of discovery
    that dance in their heads. First, the rover has a
    little more work to do to wrap the science
    campaign in Marathon Valley."

    "We saw some higher than expected currents and out
    of an abundance of caution we did some diagnostics,"
    said Seibert. "With a 12-and-a-half year old rover,
    we don't cowboy it if we see something on the drive
    train behaving out of bounds."

    This study really surprised me, I never imagined a Venus with these kind of conditions.

    It appears China's lunar rover is in a sort of "Schrodinger's box, http://spaceflight101.com/chinese-yutu-moon-rover-pronounced-dead/" or http://www.planetary.org/blogs/emily-lakdawalla/2016/08100543-yutu-is-not-dead-probably.html We may have to wait for Lunar morning when its wave function may or may not collapse. :smile:

    I also found this to be an interesting "long term look" at future programs as well as the way they are funded. http://www.space.com/33694-could-commercial-space-solve-the-astronomy-funding-wall.html

    Quantum com satellites, this is going to catch on fast.
    From, http://spaceflight101.com/qss-launch-success/
    China sent a ground breaking
    scientific experiment into orbit on
    Monday to build the foundation for
    secure communications technology of
    the future.

    The Quantum Science Satellite -
    nicknamed Micius - is the first
    spacecraft to establish quantum
    communications between space and
    Earth by creating entangled photon
    pairs over great distances and testing
    the principles of quantum teleportation.

    Very interesting ...

    Yes, very, I didn't know Quantum networks were to this point.

    The install of the IDA-2 is going well at the ISS, http://www.ustream.tv/nasahdtv
    This is video of the removal from the Dragon.

    Cool view of mars in this video link
