Attitude Control: less than 1 arcsec pointing error using a star tracker, Sun sensor, magnetometer, reaction wheels and magnetic torque rods
Telescope design The optical telescope design is based on the MOST (Microvariability and Oscillations of STars) space telescope [4]. The telescope is a 15cm diameter Maksutov Cassegrain design with two identical E2V frame transfer CCDs sharing the focal plane. One CCD is used for science purposes, while the other CCD is used as a star tracker to maintain the high pointing stability required of NEOSSat. The choice of a MOST-derived telescope design was based on a desire to a) minimize expenses while b) reducing mission risks by using a flight proven telescope design. The design of the telescope differs from MOST’s in that it includes an internal shutter (for sun protection) and field-flattening lenses to improve image quality across the focal plane. CCDs In another attempt to minimize costs a decision was made to use the flight-spare CCD’s from MOST. These flight spares had been used to test the design of MOST’s imaging electronics and to test the behavior of the CCDs under the expected on-orbit radiation environment. A technical assessment of the CCD’s was conducted and concluded that the CCDs were still acceptable for the science team’s needs.
It always makes me laugh when it's demonstrated that orbits can be maintained electromagnetically, but as far as the sun/planets/moons are concerned their overlapping electromagnetic fields have apparently no effect.

Thing about that for a few minutes.

They didn't want to re invent the wheel, so there has been success with the telescope.
The MOST microsatellite has made a major astronomical discovery. The small space telescope has revealed that the star Procyon does not oscillate. This contradicts previous observations made from Earth-based telescopes. The discovery suggests that long-held theories on the formation and aging of the Sun and other stars need to be reconsidered.
GaryN wrote..With measuring stellar oscillations yes, but there are no images from MOST. And it did discover information which overturned some long held beliefs and proves that there is a difference between Earth and space based observations, which must be an effect of Earths atmosphere.

Wavelengths 350-750 nm (Visible light)
The effective wavelength range of the instrument is limited in the red by the sensitivity of the detector and in the blue by the transmission properties of the glass used for the lenses. The filters were designed such that for a star of 10,000 K (average temperature for all BRITE target stars) both filters would generate the same amount of signal on the detector. The blue filter covers a wavelength range of 390-460 nm and the red filter 550-700 nm; both are assumed to have a maximum transmission of 95%.

Researchers at the Center for Robust Speech Systems (CRSS) in the Erik Jonsson School of Engineering and Computer Science (ECS) received a National Science Foundation grant in 2012 to develop speech-processing techniques to reconstruct and transform the massive archive of audio into Explore Apollo, a website that provides public access to the materials. The project, in collaboration with the University of Maryland, included audio from all of Apollo 11 and most of the Apollo 13, Apollo 1 and Gemini 8 missions.

How could this be verified or proved false.
Jets of material have been spewing from its nucleus, sometimes waving back and forth, as clouds of blue gas billow down the comet's strangely-formed tail.
