- What is OSIRIS-REx and where is it going?
- Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer
- Why? What is the scientific goal?
- Why this particular asteroid?
- Easy to reach
- or scientifically especially interesting.
- What sensors does the spacecraft have for the science?
- What's new? What will OSIRIS-REx do that's never been done before?
- When did it launch? How long do we expect the trip to be?
- The spacecraft itself
- sizes, weights
- bus systems (not scientific)
- Electronics, Processors, Software, Languages.
- Trajectory overview.
- Slingshot. Explain.
- What is the required precision wrt. to timing, locations, etc. to make such a slingshot work?
- Can a slingshot change the orbital plane/inclination?
- Bennu is six degrees off ...
- I thought one can only boost "in plane"?
- How have previous missions helped NASA perfect the art of the gravity assist?
- Which kinds of trajectory-altering burns are necessary
- How do you monitor, control, the trajectory?
- Longer "sleep" phases?
- What kind of propulsion? Chemical vs. Electric?
-
More like a "docking" as in Rosetta? Or real "landing"?
- What is the gravitational situation like?
- How does it "anchor" itself to the asteroid?
-
How do you technically grab the sample?
- Drill?
-
Why not do the science there?
- is it easier to get material back vs.
- bringing the lab there for in-situ analysis?
-
What kind of science do we hope to gain from studying Bennu, especially with samples here on Earth?
-
How do you determine when and where to get the sample from Bennu?
-
How to get back?
- "Reverse" the trajectory to get there feasible?
- How long will it stay? The asteroid will have moved on wrt. earth at the time of return. Different trajectory?
-
When back? arrive at Earth in 2023.
- map the asteroid in exquisite detail
- study its orbit and interior
- coincidental? Pictures of Jupiter.
