TopHeavy11 Posted December 7, 2016 Share Posted December 7, 2016 (edited) @IonStorm, I have to say that your challenge is legit. I will certainly be trying this out (for fun) as soon as unmanned asteroid sampling is added to the game via updates or mods!

I may open a new challenge during the Bennu encounter. Until then, here is the last video of the bottom of the spacecraft which will ever be taken and the first image of the sample return capsule taken in space.

MarkoeZ Posted January 6, 2017 Share Posted January 6, 2017 hmm, never posted this here i see. I bump in and out of kerbal activity a lot... But a late thanks to @IonStorm !! And i feel obliged to try again now, with Gilly mass though or between gilly and real... I really did spend hours irl hunting for the bloody thing with modded real mass... Currently doing some Jool stuff but will update here when there is something new to report. Cheers! Quote Link to comment Share on other sites More sharing options...
VaPaL Posted January 19, 2017 Share Posted January 19, 2017 (edited) A quick update: OSIRIS-REx successfully performed it's first Deep Space Maneuver on December 28th and yesterday (January 18th) also successfully performed a Trajectory Correction Maneuver. On February it will serach for Earth Trojans and on September it will do and Earth fly-by. http://spaceflight101.com/osiris-rex-aces-deep-space-maneuver/ EDIT: Well, I just notice that this is not on Science & Spaceflight, but in Challenge & Mission Ideas, but oh well...

insert_name Posted February 3, 2017 Share Posted February 3, 2017 Looks like Osiris rex will be used to map earth Trojans before EGA http://spaceflightnow.com/2017/02/01/nasas-osiris-rex-probe-moonlights-as-asteroid-sleuth/ Quote Link to comment Share on other sites More sharing options...
IonStorm Posted February 3, 2017 Author Share Posted February 3, 2017 Indeed! It is an opportunity to rehearse some of our procedures and perhaps get some science at the same time.

Thanks! Which design: dinosaur, shield, or triangle logo? Sadly, the "Kiss my asteroid!" mugs were limited edition. P.S. Breaking Bad fans will also appreciate that searching for chiral compounds is an OSIRIS-REx objective. In our case, not D-methamphetamine (dangerous drug) vs. L-methamphetamine (mild decongestant) but compounds important for the origin and evolution of life, e.g. http://www.labnews.co.uk/features/reaching-origins-life-22-10-2015/ http://pubs.acs.org/doi/abs/10.1021/acscentsci.6b00074 Quote Link to comment Share on other sites More sharing options...

This is really cool, couple questions though, how much delta v did you gain? also how did you determine when the gravity assist ended as it reached perigee earlier today ?

We got a 6° plane change, not a speed increase. The effective ∆V imparted to the spacecraft by the angular momentum exchange with Earth as a result of this flyby is 3.778 km/s. This is about 90% more than the 1.986 km/s ∆V capability in the spacecraft’s monoprop system. This velocity change does not mean that the spacecraft either speeds up or slows down by this amount, since much of this change is used change the orbit inclination. There is no EGA event, but the countdown clock was at closest approach. The observing campaign lasts 10 days after with downlinks at EGA +1, +3 and +10. The navigation team breathed easier after contact with Goldstone was re-established after crossing into the western hemisphere with no errors or interruptions.

I always wondered why some High gain antennas are covered like the one on OSIRIS-REx and Juno, where as older Spacecraft don't seem to be build that way. What is the purpose or Advantage of these covers? Quote Link to comment Share on other sites More sharing options...
Ultimate Steve Posted September 22, 2017 Share Posted September 22, 2017 Good gravy, it's already been a year? Anyway, good luck with the mission to everyone working on it (particularly @IonStorm). Hopefully the spacecraft will have another encounter with Earth in a few more years, bearing space-rocks. Quote Link to comment Share on other sites More sharing options...

We use Germanium Black Kapton (GBK) which provides better electrostatic dissipation than the gold kind. Quote Link to comment Share on other sites More sharing options...
IonStorm Posted September 27, 2017 Author Share Posted September 27, 2017 Data! Science! Gravity! The Earth Gravity Assist went perfectly with the trajectory right down the middle (blue line, the green, yellow, and red are 1, 2 and 3 sigma errors to the 2-way X-band Doppler residuals during the EGA). And the images and spectra look great. http://www.asteroidmission.org/?latest-news=osiris-rex-views-earth-flyby Now on to Bennu, http://52.222.55.61/ http://www.lizard-tail.com/isana/orb/misc/osiris_rex/ Quote Link to comment Share on other sites More sharing options...

I'd be happy to if there is enough interest. I can create a new challenge at arrival in RSS if someone makes a Bennu model based on real data.
