LBT snags first glimpse of OSIRIS-REx since launch

OSIRIS-REx is  a NASA spacecraft traveling to a near-Earth asteroid called Bennu to bring a small sample back to Earth for study. The mission launched Sept. 8, 2016, from Cape Canaveral Air Force Station. As planned, the spacecraft will reach Bennu in 2018 and return a sample to Earth in 2023.

The spacecraft is currently approaching Earth for its gravity assist maneuver, which will change its trajectory and set it on course to rendez-vous Bennu. Its closest approach to Earth is scheduled for 12:52 p.m. EDT on Friday, Sept. 22.

The Large Binocular Telescope Observatory (LBTO) used the LBCs (Large Binocular Cameras), a pair of wide-field cameras at the prime focus of each of its two 8.4m mirrors, to image the field around the predicted position of the spacecraft on the night of September 1.

The animation above (three images - LBCB - 300s exp. time - V filter) centered on OSIRIS-REx (red square).  2017 September 2 at around 11:00 UTC. The spacecraft was 11-million kilometers away from Earth at the time of the observation. The spacecraft was  28% illuminated with a magnitude V~25.


On that night, LBTO was back on sky after a long period of shutdown which started on June 15 due to the Frye fire, followed by its seasonal monsoon shutdown (Jul 10 - Aug 31). OSIRIS-REx was an excellent target of opportunity at the beginning of a 12-night period dedicated to a full restart of the facility. A good way to come back to observing after 2.5 months of closed dome!


Thanks go to V. Reddy and A. Conrad for proposing the target, B. Rothberg, O. Kuhn, J. Hill and S. Allanson for observing, C. Veillet and C. Hergenrother for the data reduction, and the whole LBTO staff for a great shutdown work!

  7. ...space-elevator (orbital station bike wheel-1g)... geostationary orbit, a huge "bike-wheel" is gyrating around its own axis for have 1g-centrifugal. Wheel held in place with 4 CABLES (each cable with a track for Train, for both trains crossing ↓↑) FORMING THE STRUCTURE OF A RHOMBUS♦ (minor diagonal of rhombus is the gyration-axis of the Station-Wheel)...rhombus´s below, the carbon nanotubes Track towards Earth...rhombus´s above, the Cable towards a higher counterweight... if...WHEEL´s RADIUS = 250 mts... Wheel gyration´s Axis length = rhombus´s minor diagonal = ½ Wheel´s radius = 125 mts (axis could be a resistant hollow tube with for example 20 mts in diameter with an adequate wall´s thickness, hollow which could serving how tank of anything, e.g. air, or tank of frozen water storage no totally full, for volume expansion from liquid to ice without tank, Axis, breaking, thawing using solar-heat)... Cable´s length of the rhombus´s side = Wheel diameter = 500 mts ((also how Wheel´s supporting, instead of a rhombus, can be a narrow Rectangular structure ▄▄▄▄▄▄ of rigid girder with dimension sides slightly majors than Wheel´s diameter and wide, e.g. Wheel´s diameter 500 mts and wide 50 mts...rectangle´s sides: 510 mts length, 60 mts wide. Rectangle with a cable/track (length=Wheel´s diameter) in each vertex, forming a long isosceles triangle ───◄at both rectangle´s minor sides►───)). Wheel´s ZONE-1g: habitable length = 1571 mts*50 mts wide (separation at both sides between Cable and Circumference of the gyratory Wheel, approx.= 5 mts, adjusting this separation installing an Axis with major or minor length, as much as shorter Axis...stronger and, for easy train´s passing, and angle nearer to 180º value in both rhombus´s-vertx, minor diagonal, where are the Big Soundless-♫-Bearings of Axis´s-insertion...a few Electrical Motors fed with Solar-Energy maintain automatically the gyration-speed counteracting the slow braking by friction from the Bearings...besides or Bearings: main Maglev system also for the gyration and Axis´s supporting, leaving the Bearings only how secondary security system...with a slight roominess between each Bearing and its exterior subjection, into the roominess all around...little solid Pistons radial extensible and retractable... Axis´s subjection: extensible ON, with Bearings; extensible OFF, with Maglev. With a sufficient cables tension coming from the counterweight, if Axis resists: the rhombus structure is undeformable)*10 Floors with 25 mts in height each one, gyrating 360º each 31 seconds, angular-speed = 11.61º/sec, linear-speed (tangential) = 182 kms/h... Station-Wheel´s GYRATION: AXIS IN PERPENDICULAR (90º) ORIENTATION TO THE ORBITAL TRAJECTORY...and so, while Station-Wheel follows its geostationary orbit, the Wheel does Not change the spatial-orientation of its axis, and thus there are Not Precession forces actuating (and thus there is Not torsion´s force against Track)...

  8. (2)...space-elevator (orbital station bike wheel-1g)... Wheel with maneuver´s tangential-rockets for gyration´s start, or...gyration emergency stop...and maneuver´s axial-rockets for reorientation of Wheel´s axis, if it is necessary: because the Earth´s axis slightly and very slowly goes oscillating cyclically due to nutation and precession...that oscillation evidently produces transversal traction pulling of the Track towards aside from its anchoring on equator, thus would have an also slight pendular movement side to side and it would produce precession´s movements of the Wheel´s axis and thus a not wished torsion of the Track...but the system must supporting lateral charges, in the same orbital plane and thus without precession´s problems on the Wheel´s axis, of acceleration against W→Track←E produced by the Coriolis effect when movement´s direction is perpendicular to the gyration´s axis, that lateral charge is maximum on equator (there, a vertical movement is perpendicular tø Earth´s axis) and zero on poles (there, a vertical movement is parallel tø Earth´s axis); upwards charge to West, downwards charge to East; the gyroscopic-rigidity contributes for maintaining the gyration-axis perpendicular to the orbital trajectory... When the Maglev Train slowly arrives (Train with one opened ╚╝ side in its technical maglev-zone train´s all along over Track for can passing for both tracks: main-Track/rhombus-track/again Maglev-Track), using now cogwheels on Zipper-Track (zippers installed on the same Maglev-Track), Train stops in Geo 0g-Station placed over one Extreme of the Gyration-Axis, next to «Port for Spacecrafts»... Passengers disembark and entering into gyratory circular corridor, they take now the interior-elevator of one of the Wheel´s hollow-radius (also could be an exterior-elevator running for a simple zipper-radius), and tunnel "descending" till Hotel into the final Zone-1g...where while Station-Wheel goes turning, the immense O2 producer Hydroponics Garden receives a filtered Sun light...and there are Earth´s awesome views.

  15. ...interstellar travel constant acceleration (return to Moon)... "We do not can return to Moon"...recent declarations of an astronaut. In reality is: We do not can return to Moon, because on Moon there are Extraterrestrials, or they did stay in times past and remain their city ruins. Apollo astronaut transmission from Moon (TV): "...they are here, on aside crater, watching us...". We do not can return to Moon because still the religious are who command in the shadow over the World and their "gods" only "are" on Earth. When the Extraterrestrials will coming to Earth: Goodbye religion and its Lies. For that reason "We do not can" return to Moon, because "God" is the same Universe, a mineral and insensitive Being who permits the suffering of the innocents in that "Third World" intentionally maintained because WITHOUT POOR AND IGNORANTS THERE IS NOT RELIGION. For that reason "We do not can" return to Moon, because there is no other Life in none "life-beyond", the unique Immortality it is coming from We self: Technological Immortality. For that reason "We do not can" return to Moon...yet.
