OSIRIS-REx Spacecraft Check Out and Early Cruise Phase Activities

It has been awhile since I posted anything to this site. The launch of OSIRIS-REx was such an amazing, emotional experience; it took me about a month to come back down to Earth (pun intended). I have now settled into a normal work routine in Tucson and the team has been busy operating the spacecraft […]

OSIRIS-REx – Day 2 in Space

       Our spacecraft continues to operate flawlessly. Kudos to the operations team members who have been tracking and operating the spacecraft since separation! Here are some details on recent status.      After a flawless launch day, day 2 has also progressed as planned.      We have completed the Countup Procedure and the spacecraft has […]

39 Days to Launch – What’s Left to Get Done?

With only 39 days to go until we launch OSIRIS-REx our schedule is packed with activities. Here is a quick rundown of what the team has left to do to get ready to blast this asteroid-sampling robot into space. 8/2: Mission Event Readiness Review – DSN/JPL The Deep Space Network (DSN) is a critical component […]

The Journey to Kennedy Space Center

The OSIRIS-REx project continues to progress seamlessly through the Assembly, Test, and Launch Operations (ATLO) phase. We are now done with the AT portion of this phase and have started LO. The test phase ended with the completion of the last major environmental test: the thermal vacuum test. With the test program complete, the team […]

OSIRIS-REx – Seeking Answers to the Sweet Mystery of Life

Guest Blogger: Jason Dworkin   The nature of the origin of life is a topic that has engaged people since ancient times. Where did we come from? What was the first life? How are we related? Are we alone? The study of biologic remains and environments preserved in rocks (fossils) and biochemical pathways and structures […]

OVIRS Development – Rising From the Ashes

Guest Bloggers: Jason Hair, Dennis Reuter, and Amy Simon Building a mission or an instrument is not for the faint of heart. While engineering teams develop plans to avoid major mishaps, sometimes even the best laid plans aren’t enough. A case in point is a series of unfortunate events that happened to the OVIRS instrument […]

Bennu's Journey is a 6-minute animated movie about NASA's OSIRIS-REx mission, asteroid Bennu, and the formation of our solar system.

The Science of “Bennu’s Journey”

This week the OSIRIS-REx project released Bennu’s Journey, a movie describing one possible history of our target asteroid – Bennu. The animation is among the most highly detailed productions created by Goddard’s Conceptual Image Laboratory. It is the result of an exciting collaboration between the OSIRIS-REx Science Team, Walt Feimer and Michael Lentz, from the […]

The OSIRIS-REx Visible and near-IR Spectrometer (OVIRS) – Measuring the chemistry and reflectance of Bennu

Guest Blogger: Amy Simon – OVIRS Deputy Instrument Scientist OSIRIS-REx will map the entire surface of asteroid Bennu to pick a site that is most accessible and likely to yield a sample, but is also scientifically interesting. Choosing the best site requires understanding both the local geology and the local composition; a prime goal of […]

A Successful Critical Design Review!

Yesterday marked the final day of the OSIRIS-REx Critical Design Review (CDR). This review began on April 1, 2014 and spanned nine days – with one day off in the middle. Over 60 OSIRIS-REx team members presented almost 1,600 PowerPoint charts in 56 hours. Since a CDR is required for all elements (i.e., spacecraft, instruments, […]

Sampling an Asteroid – A Game of Laser TAG

Every spacecraft mission has at least one moment of terror. For OSIRIS-REx, mission success comes down to the five seconds when our Touch-and-Go Sample Acquisition Mechanism (TAGSAM) “kisses” the surface of asteroid Bennu to acquire a sample. Our TAG-based sampling approach is the result of over ten years of research and development efforts. To Land […]
