On 12 November, Rosettas Philae probe is set to make the first-ever landing on a comet when it touches down on Comet 67P/ChuryumovGerasimenko.

 

Separation of the lander is planned for about 09:03 GMT (10:03 CET), and touch down should follow about seven hours later, at 16:02 GMT (17:02 CET).

This will be fucking cool. We'll learn shit tonnes about comet composition (and by extension, learn a lot about the composition of Kuiper Belt / Oort Cloud objects in general, and thus solar system formation etc etc). It's also fun to see how wound-up the Electric Universe cranks are getting over this mission.

 

Also look out for New Horizons' flyby of Pluto, which is late next year I think? That will be similarly groundbreaking / IDM

During checks on the lander’s health, it was discovered that the active descent system, which provides a thrust to avoid rebound at the moment of touchdown, cannot be activated.

At touchdown, landing gear will absorb the forces of the landing while ice screws in each of the probe’s feet and a harpoon system will lock Philae to the surface. At the same time, the thruster on top of the lander is supposed to push it down to counteract the impulse of the harpoon imparted in the opposite direction.

“The cold gas thruster on top of the lander does not appear to be working so we will have to rely fully on the harpoons at touchdown,”says Stephan Ulamec, Philae Lander Manager at the DLR German Aerospace Center.

“We’ll need some luck not to land on a boulder or a steep slope.”

“There were various problems with the preparation activities overnight but we have decided to ‘go’. Rosetta is lined up for separation,” says Paolo Ferri, ESA’s head of mission operations.

First comet first served

 

First contact :w00t:

 

*edit*

 

But this is proper cool, if it works and we can nail the technology then the scope for "hitching a ride" on comets in the future will be immense. Let the comet do all the work and we just sit there anchored into place chillin' in cryo sleep

Yeah indeed man - seems like that might significantly reduce its chances of a successful landing. We'll know in 1.5 hours! Nearly completed its descent.

This is awesome. Thank you.

      Superb spacey experimental techno from Zachary Lubin
      Out on Jeff Mills imprint AXIS records.
      I absolutely LOVE the first intro beatless track especially.

      if any of you follow space travel, you will know this Thursday marks the first orbital test flight of NASA's new manned deep space rocket, the Orion Space Vehicle.  it will be perched atop one of the largest rockets ever assembled, the Delta 4, and by now actually is, it's completely assembled on Launch Complex 37B at Cape Canaveral.  this site has a ustream feed and a countdown clock, so check it out.  the next era of manned space travel is about to begin, after the retirement of the beloved Space Shuttle.
       
      "A United Launch Alliance Delta IV will herald a new era in manned Space Flight with the launch of the Orion capsule for the new Space Launch System (SLS)."

      "The Delta IV will be in the heavy configuration with a common core booster and two identical strap-on boosters. This will be the seventh Delta IV Heavy to launch from the Cape Canaveral launch site and the ninth overall."

      Had a jam with some hardware stuff yesterday. I plan to do more these in future, just combining various gear in different combinations and see what comes out. The sequences were made earlier but the arrangement was fairly improvised.

      This is not  "new" as far as it's been produced between 2005 and 2014, but exept giving some cd-r when having live gigs, this have never been released or uploaded on the internet so far.
      Almost everything is hardware, raw 2-tracks recording out of analogue mixing desk (no daw multitrack mixing, no editing, no post-prod, just go and rec,  just a bit of mastering process).
      If you go for a listen, I suggest you to start by the most recent ones (coz' more interesting i.m.o.)   though, if you're into ambient, you should try the older "venale suite" or "etorpe winter harvest".
      I also have some more  jungle / drumn bass stuff, that I still have to pack and upload.
      Last recent years I was more busy working with another project in duet with a friend, (live techno / breakbeat / rave stuff), that I will post a bit later.
      Well also last years I was very busy working and raising kids... but I'mactually back in the studio so I hope I will soon put out some more music !
      Feedback is welcome ! Cheers !
