Ready for the Earth Gravity Assist!

It is hard to believe that OSIRIS-REx has been in space for over one year. We celebrated the first anniversary of our launch on September 8, 2017. I celebrated this milestone by visiting my hometown Boys and Girls Club in Phoenix, AZ, where I grew up. As the plaque in this image shows, I was […]

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).

We are now less than one year to launch and only eight months away from shipping the spacecraft down to Kennedy Space Center for integration with the Atlas V launch vehicle. As I recently reported, the spacecraft is in great shape and is almost complete. […]

The OSIRIS-REx Heavy Launch Opportunity

As recent press articles have discussed, the OSIRIS-REx team has been busy performing a special study related to our launch mass and propellant load. The objective of this study is to look at ways to increase the OSIRIS-REx spacecraft delta-V capability as much as possible without impacting the current spacecraft or launch vehicle designs. Delta-V […]
