******************************************************************************* Revised: Oct 23, 2023 OSIRIS-REx/APEX Spacecraft / (Sun) -64 http://www.asteroidmission.org https://directory.eoportal.org/web/eoportal/satellite-missions/o/osiris-rex http://www.nasa.gov/sites/default/files/atoms/files/osiris-rex_press_kit_0.pdf NOTE: 2024-Apr-19 A preliminary extension from 2026 through Apophis encounter has been added. There is large jump at the 2026 merge right now. 2023-Sep-18 The OSIRIS-REx project indicates the June 1 trajectory remains accurate, no update prior to flyby is expected. 2022-Apr-25 Mission was approved for 18-month Apophis rendevous, to be renamed "OSIRIS-APEX" 2017-Sep-22 Earth gravity-assist flyby: Closest-approach is nominally at 16:51:46 UTC, 23592 km from Earth center, over 271.89346 deg. E, -74.80121 deg. (South). This is over Antarctica, south of the tip of South America, about 420 km north of Vinson Massif, the highest point in Antarctica. BACKGROUND OSIRIS-REx ("Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer") explored 101955 Bennu (1999 RQ36), a carbonaceous B-type asteroid whose regolith may provide insights on the early history of the solar system. After the sample was returned to Earth, in 2023, the mission was retargeted to encounter asteroid Apophis in 2029 and renamed OSIRIS-APEX ("APophis EXplorer"). MISSION EVENT SUMMARY (UTC) 2016 Sep 08 23:05 Launch from Cape Canaveral; daily 120 minutes windows from Sep 8 - Oct 12. Atlas V w/Centaur upper stage. 2017 Sep 22 16:52 Earth flyby and gravity assist 23,592 km from geocenter over {-74.80121 deg. S, 271.89346 deg. E} 2018 Aug Bennu approach phase Oct Rendevous with asteroid Nov Estimate mass, shape, and spin state models Dec 3 Proximity ops began 2019 Jan Begin detailed mapping; identify candidate sample sites May Sorties to examine 4 candidate sample sites Oct Fly over candidate sample sites 2020 Apr First sample-collection rehearsal Aug Second sample-collection rehearsal Oct 20 Collect sample > 60 grams 2021 May 10 Start return cruise and transport sample back to Earth 2023 Sep 24 Sample Return Capsule (SRC) recovery on Earth 2023 Oct 24 Retargeting maneuver for Apophis (OSIRIS-APEX) MISSION OBJECTIVES * Map the asteroid * Return and analyze a sample of Bennu's surface * Document the sample site * Measure the orbit deviation caused by small non-gravitational forces * Compare observations made at the asteroid to ground-based observations SPACECRAFT PHYSICAL DATA: Length : 20.25 ft (6.2 m) with solar panels deployed Width : 8 ft (2.4 m) x 8 ft (2.4 m) Height : 10.33 ft (3.2 m) TAGSAM Length : 11 ft (3.4 m) ("Touch-and-Go Camera System") Dry mass (unfueled): 1,940 lbs (880 kg) Wet mass (fueled) : 4,650 lbs (2,110 kg) Power : Two solar panels 91 ft^2 (8.5 m^2) generate 1226 to 3000 watts, depending on distance from the Sun SPACECRAFT TRAJECTORY Updated as the mission progresses. NOTE: To generate ephemerides OF destination asteroid Bennu as a target using the final reconstructed solution (Farnocchia et al, 2021), look-up with integer code "2101955" (NO semi-colon). To instead use asteroid Bennu as an observing point (produce ephemerides relative TO Bennu), set the coordinate center to "@ 2101955". Similarly, the Sample Return Capsule can be accessed as object '-64090', Apophis mission trajectory as object '2099942' Trajectory name Start (TDB) Stop (TDB)

******************************************************************************* TIME Barycentric Dynamical Time ("TDB" or T_eph) output was requested. This continuous coordinate time is equivalent to the relativistic proper time of a clock at rest in a reference frame co-moving with the solar system barycenter but outside the system's gravity well. It is the independent variable in the solar system relativistic equations of motion. TDB runs at a uniform rate of one SI second per second and is independent of irregularities in Earth's rotation. CALENDAR SYSTEM Mixed calendar mode was active such that calendar dates after AD 1582-Oct-15 (if any) are in the modern Gregorian system. Dates prior to 1582-Oct-5 (if any) are in the Julian calendar system, which is automatically extended for dates prior to its adoption on 45-Jan-1 BC. The Julian calendar is useful for matching historical dates. The Gregorian calendar more accurately corresponds to the Earth's orbital motion and seasons. A "Gregorian-only" calendar mode is available if such physical events are the primary interest. REFERENCE FRAME AND COORDINATES Ecliptic at the standard reference epoch Reference epoch: J2000.0 X-Y plane: adopted Earth orbital plane at the reference epoch Note: IAU76 obliquity of 84381.448 arcseconds wrt ICRF X-Y plane X-axis : ICRF Z-axis : perpendicular to the X-Y plane in the directional (+ or -) sense of Earth's north pole at the reference epoch.
