Ready for First Pass (E. Atz, Sep. 25, 2021)
The CuPID team has gotten the ground station computers and accompanying software prepared for launch on Monday the 27th! After spending two days fighting with motors on the antenna, the ground station is fully functional and ready for PI Brian Walsh to establish contact as soon as we get orbit... More
Integration at Vandenberg Space Force Base! (E. Atz, Aug. 12, 2021)
Last week, CuPID was integrated into the flight deployer and ESPA ring at Vandenberg Space Force Base in Lompoc CA. The team hand carried CuPID over commercial airline to LA, and then via rental car to Lompoc. Integration went smoothly, there were no problems with cleanliness checks, travel, or the... More
CuPID Survives Vibe… Again! (E. Atz, Jul. 9, 2021)
Last week, requirements for the Cubesats riding on this launch changed unexpectedly. We were required to re-test the satellites to higher vibration levels to guarantee that our satellites will behave during launch, and will do no harm to the launch vehicle. On Friday July 2nd, with incredible assistance from our co-workers... More
CuPID Survives Vibration Testing! (E. Atz, Apr. 6, 2021)
Last week, CuPID underwent vibration testing as part of its environmental test requirements from the launch provider. CuPID survived the extreme vibrations we gave it, and showed nominal operation after the test. Accelerometers are mounted to the vibration plate to define the driving forces, as well as specific location on CuPID... More
Star Tracking in the Winter in Boston (R. Nutter, Jan. 13, 2021)
Like many spacecraft, CuPID uses a star tracker to identify its pointing or attitude. The star tracker uses a catalog of stars and compares with observations of measured star patterns to identify pointing at a given moment in time. After a brief failed attempt at viewing through the light pollution from... More
CuPID’s first time outside (R. Nutter, Jun. 2, 2020)
The past few weeks have been full of X-ray calibration testing. But this week we shifted to a test of CuPID’s ability to track GPS satellites. If successful, the ability to track GPS satellites will allow us to triangulate CuPID’s position at any given time. To best do this test... More
The testing must go on! (E. Atz, Apr. 26, 2020)
Individually, CuPID's structure and electrical components have been tested, but now integrated, we are requiring CuPID to go through many more tests to fully confident that CuPID will work as designed once in orbit. From just confirming functionality of all sub-systems to calibrating the instruments, CuPID has been spending a... More
Integration! (E. Atz, Feb. 17, 2020)
In the recent weeks, the CuPID chassis and avionics met for integration. This process involved mounting the avionics into the chassis and then wiring all the components together through the spacecraft. After many hours of work with screwdrivers, wire crimpers and lacing cord, we powered the spacecraft on. With much... More
Glasses for CuPID? (E. Atz, Oct. 15, 2019)
Optics in a telescope are just like glasses to improve someone's sight. In the case of visible light, the glass lens refracts the light to the desired pattern. With x-rays, the optics can only deflect the incoming light because the x-rays would pass right though! These optics, called slumped micro-pore... More
The Instruments Meet Each Other! (E. Atz, Aug. 30, 2019)
This week, Brian, Jef and I delivered the CuPID micro-dosimeter to Nick , Norm and Michael at Goddard Space Flight Center where the CuPID chassis and X-ray instrument currently reside. Until now, the instruments have been built and tested separately. After some individual testing that morning to document functionality, the... More
