New Shepard lands for the fourth time (image © Blue Origin)
Very nice to see Blue Origin join the club with a very nice live webcast of the fourth flight of the same New Shepard rocket and capsule. The combination of the double sonic boom and the incredible speed at which the booster comes down always impresses me. This flight also proved that the capsule could land safely if one parachute fails to open, as planned — Blue Origin seems to be advancing steadily towards human qualification for its rocket and capsule.
I find it amazing that we live in a time where not one, but (at least) two companies are now actively working on landing rockets after their missions. And even though New Shepard’s flight profile is much easier on the rocket than Falcon 9’s, it’s pretty great to see the same hardware fly four times!

For the past three years I’ve found myself incredibly lucky: for the first time, I’m happy to go to classes because what I’m learning, what I do for coursework is a passion of mine. I like programming, I love learning about computer architecture, I enjoy cryptography (nerd).
I’ve always thought that it could be the best thing to happen to anyone. Not worrying about going to work everyday, because you know you’re going to love it. Of course, it can only a blessing, right?

A simple wallpaper set I made from the design painted on the decks of SpaceX’s Autonous Spaceport Droneships. I made a version for each of the ships, Of Course I Still Love You (used for launches out of Cape Canaveral and Kennedy Space Center) and Just Read The Instructions (used for launches out of Vandenberg).

I was crossing all ten fingers yesterday night when the first stage of Falcon 9 came into view. By the time it touched down and the engine turned off, I was jumping on the spot (and maybe crying a little). I’d missed their first landing in December, and that tall, skinny stage aiming for an autonomous barge just looks straight out of Science Fiction. I think what’s most impressive about this launch and landing is that SpaceX made it look effort-less, which it definitely can’t have been. Congratulations to every person that spent months making it work!
According to Elon Musk during the press conference after the launch (and landing), this stage will be test-fired around ten times. If that goes well, then it’ll go through qualification to hopefully fly on a new orbital mission in June. Reusability is not a done deal yet, but yesterday’s landing felt like a historic moment.

Had the RD-180 engine shut one second earlier than it did, Centaur would not have been able to compensate and Cygnus would have ended up in a lower orbit. With Shutdown another 1.3 seconds earlier, there would not have been a mission for Cygnus as perigee would have remained within the atmosphere, even when using all of Centaur’s performance.
– Spaceflight 101
SpaceFlight101 breaks down Atlas’s launch from last week in amazing detail. It shows how little margin you get when you hurl things towards space. Tip of the hat to Centaur, which did an admirable job saving the mission, and good luck to ULA’s teams for the next step — figuring out what went wrong and fixing it and make Atlas V even more reliable.
2015 has been pretty crazy. I’ve stalled a bit lately when it comes to creative stuff, so I thought it would be a good idea to look back on things I’ve done and seen this past year (the idea came from Susan Lin’s very similar post).
This is a bit less formal than I usually post here, but that’s one thing I really want to do in 2016: use this blog more often, without having to (badly) write long pieces every time: I want to be able to use it more as a log than a place to post nice writing — which I won’t stop posting when I feel like it. Happy New Year!

The band opens the Family Jewels act with Mowgli’s Road.
After Marina released her last album, Froot, I managed to get a ticket for the Neon Nature concert in Glasgow (at the O2 abc, a pretty small, nice venue) before everything sold out. The show was organised in three acts — one dedicated to Froot, of course, but also one of each of her previous albums.
Seconds before Electra Heart steps on stage.
Everything was great: the setlist was a pretty good mix of old & new, dancing & slow-paced. The whole band was great, from the frantic drummer to the ever-happy guitarist. Marina was glowing and energetic, putting a smile on everyone’s face. The audience was lovely too — the whole venue singing Happy with Marina during the encore was very touching.
After the Electra Heart act, going into Froot.
I had an amazing time — I can’t remember another concert that put me in such a happy, cheerful mood. It’s hard to thing it was a month ago already. My only regret? The absence of some songs (Better Than That, Starring Role…) from the setlist. Too bad, I’ll have to go to the next one!
Something you don’t see every day: a rocket coming home after a job well done
After a hiatus of six months following the failure of the CRS-7 mission last may, SpaceX returned to flight yesterday. Falcon 9 Full Thrust not only placed its 11 Orbcomm satellites in orbit — the first stage executed its return sequence perfectly, and came to perfect stop on SpaceX’s Landing Complex 1. I was impressed by Blue Origin’s landing in November, but this is on a whole new level.
