On September 22, 2016, two weeks after launch, the OSIRIS-REx spacecraft switched on the Touch and Go Camera System (TAGCAMS) to demonstrate proper operation in space. This image of the spacecraft was captured by the StowCam portion of the system when it was 3.9 million miles (6.17 million km) away from Earth and traveling at a speed of 19 miles per second (30 km/s) around the Sun. Visible in the lower left hand side of the image is the radiator and sun shade for another instrument (SamCam) onboard the spacecraft. Featured prominently in the center of the image is the Sample Return Capsule (SRC), showing that our asteroid sample’s ride back to Earth in 2023 is in perfect condition. In the upper left and upper right portions of the image are views of deep space. No stars are visible due to the bright illumination provided by the sun. Credit: NASA

No stars are visible because 1) the exposure time was too short to see any, and 2) Stowcam is focused on the SRC and stars would be way out of focus.

Oh, and thanks for the image credit. rolleyes.gif

Pretty!
Images from a spacecraft showing both part of itself and the background of space are always so cool to me, and I imagine many others. Philae's image of the Rosetta solar panels with 67P (or Mars) in the background was emblematic of the whole mission. Can't wait for Bennu to make a background cameo...

Looks like a search for Earth trojans is going to be done in February during the trip to Bennu (can the thread title be changed with the new name?)

Admin- Yep! Done. smile.gif

Here is an article about the upcoming search for earth trojans at the L4 point which is just about to get underway:

Asteroid sleuth

QUOTE
Between Feb. 9 and Feb. 20, the spacecraft’s mapping camera will take 145 pictures per day of the volume of space where Earth-Trojans are expected to reside, according to Lauretta.
“It’s a big cloud, and there should be material there,” Hergenrother said at a Jan. 12 meeting of NASA’s Small Bodies Assessment Group. “We should be able to detect stuff down to 100 meters (330 feet), and possibly even smaller, depending on the performance of our cameras, and the albedo (reflectivity).
“If we don’t find anything, it either means there’s a lot less objects out there than we were thinking, or they’re a lot smaller,” Hergenrother said.

MapCam view of the Jupiter system from the Earth Trojan asteroid search. From left to right, Callisto, Jupiter, Io and Europa. Released on Valentine's Day nonetheless! Is OSIRIS-REx sending a message to Juno? wink.gif

You can see the belts in this one! Another reminder that Polycam is powerful!

Spacecraft spotted! http://www.asteroidmission.org/?latest-new...ft-since-launch

I'm sure it must be mentioned somewhere, any plans for the spacecraft to do some imagery of its own?

At 4:52 p.m. EDT, four hours after closest approach, OSIRIS-REx will begin science observations of Earth and the Moon to calibrate its instruments.

Closest approach has passed, and according to DSN, they made contact and are downlinking...

First Earth image released! https://www.nasa.gov/image-feature/goddard/...th-during-flyby

And for comparison, an image from EPIC on board DSCOVR, around the same time: https://epic.gsfc.nasa.gov/archive/natural/...70922224114.png

I have to admit a bit of surprise at the quality. Are these images actually circular rather than rectangular? And can we expect those drop outs (?) as the "norm"?
