NASA’s Touch-and-Go Mission to Asteroid Bennu a Success


Photography and space exploration have gone hand-in-hand since pretty much the very beginning.

It’s amazing that, no matter how complex some of these missions might be from a technical standpoint, we as humans often value visual confirmation over everything else. After all, the saying is “Seeing is believing” and in the world of photography and beyond, that is very much the truth.

As confirmation of a successful landing on the asteroid Bennu, an object some 220 million miles away from Earth, NASA compiled an 82-image slideshow that shows the whole thing. Formally called the OSIRIS-REx mission, the goal was to land on the surface then launch off of it in order to gain a sampling of material from the asteroid.

As NASA explains in their blog post about the complex operation to make it to Bennu:

“The spacecraft’s sampling arm – called the Touch-And-Go Sample Acquisition Mechanism (TAGSAM) – is visible in the lower part of the frame. The round head at the end of TAGSAM is the only part of OSIRIS-REx that contacted the surface during the sample collection event. In the middle of the image sequence, the sampling head positions itself to contact the asteroid’s surface head-on. Shortly after, the sampling head impacts site Nightingale and penetrates Bennu’s regolith. Upon initial contact, the TAGSAM head appears to crush some of the porous rocks underneath it. One second later, the spacecraft fires a nitrogen gas bottle, which mobilizes a substantial amount of the sample site’s material. Preliminary data show the spacecraft spent approximately 5 of the 6 seconds of contact collecting surface material, and the majority of sample collection occurred within the first 3 seconds.”
