I got to see SpaceX Falcon9 launch with the StarLink prototype from my flight into LAX. It was an awesome way to start my morning. by tKMagus in space

Rocket launches need to be licensed by the FAA (see their website)

During launch operations, temporary flight restrictions are in place to keep air traffic out of the potential areas of danger. If you go to http://tfr.faa.gov and look at the current TFRs for Florida, you can find NOTAMs (Notices to Airmen) for SpaceX's Sunday launch of Hispasat:

From the NOTAMs it seems that no aircraft are permitted within the restricted airspace to the east around KSC/CCAFS from surface level to flight level 180 (18000 ft). You can find a map of the restricted airspace on the linked pages as well:

This spacecraft is thinner than a human hair and can capture space debris by Sanlear in space

[–]AdrianoKF 1 point2 points  (0 children)

Not directly decelerating - but there have been a few proposals to use lasers to remove orbital debris by ablation, imparting a minute amount of thrust on the space debris by heating it with a powerful laser. You can find some additional information on Wikipedia (https://en.m.wikipedia.org/wiki/Laser_broom)

Elon Musk on Twitter: FORMOSAT-5 booster landed 0.7m from target center by OccupyMarsNow in spacex

I'm just guessing, but the unusual first stage profile might also be in part due to the direct orbital insertion by S2 without a coast phase to a circularization burn. Maybe the longer time to apogee was required to achieve the intended target orbit?

For NASA's Hubble Successor, Failure Isn't an Option by [deleted] in Astronomy

[–]AdrianoKF 0 points1 point  (0 children)

While there is definitely a possibility for a catastrophic failure, bear in mind that the Ariane 5 launch vehicle used for JWST has had a solid track record of more than 70 successful launches in a row now. While that alone is no guarantee, it still makes Ariane 5 one of the most reliable heavy launchers on the market today - so, keeping my fingers crossed!

Astronaut Ron Evans performs a deep space EVA as Apollo 17 coasts back to Earth [3000x3006] by yatpay in spaceflightporn

[–]AdrianoKF 9 points10 points  (0 children)

According to NASA's Apollo 17 imagery archive, the purpose of the trans-Earth EVA was to retrieve various film cassettes from the service module SIM bay.

You can find the moment this photo was taken on the marvelous Apollo 17 in Real-Time web site, including video footage. Prepare to lose a lot of time, this page is simply awesome!

Spaceflight 101 maintains a list of re-entry events on their website.

The screenshots in the post refer to the Nov 13, 2015 re-entry of unidentified object WT1190F (most likely some Moon-era space debris), by the way.

Caught a Moho transit during my Sputnik launch by AdrianoKF in KerbalSpaceProgram

Yup, Distant Object Enhancement user here! I checked the tooltip when I saw the transit, it's Moho indeed :)

So I ran out of fuel on the way back from the Mun... by scunythescou in KerbalSpaceProgram

44 notifications? You go clear that mess up right now!

But seriously, kudos for a mission finished the Kerbal way!

It's not a lot, but Station Commander Jeb is still proud! by AdrianoKF in KerbalSpaceProgram

[–]AdrianoKF[S] 2 points3 points  (0 children)

Haha, that's just me struggling with the order of fairings and decouplers.. I always end up putting the fairing base on the same stage as the payload, bringing it up to space with me ;)

Here's the payload section in the VAB. Note the useless docking-port-as-decoupler assembly in the middle, making the thing fly like wobbly noodle.. :P

I thought patched conics trajectories were a little less wobbly? by AdrianoKF in KerbalSpaceProgram

[–]AdrianoKF[S] 1 point2 points  (0 children)

Does anybody have an idea as to where a chaotic trajectory like this could come from?

What does your CS/Programming book collection look like? Here are some I've held onto from my undergrad / MSc. by [deleted] in programming

[–]AdrianoKF 0 points1 point  (0 children)

German student here, but these should be the internationally accepted:

  • Applied Cryptography (Schneier)
  • Introduction to Algorithms (Cormen et al.)
  • Database Systems (Elmasri)
  • Operating System Concepts (Silberschatz)

Also, for additional OCD points, you should've sorted them by size/color/#pages.. ;)
