#BUSYCONTACTS VS DAYLITE FULL#
This work summarizes the current status of the ALEXIS project, its scientific goals, and the prospects for full mission recovery. Scientific results from data already in hand and those to be collected will not be possible until this task is complete. Faster-Cheaper satellite, with a 1 year nominal and a 3 year design limit. Constructed from high-quality bluesign approved recycled fabrics, GRS-certified recycled polyester and a PFC-free DWR coating. Reach for it when running everyday errands, going for a quick hike or heading out of town. In order to fully analyze the telescope data, a new algorithm implementation to determine telescope pointing information is under development. Lightweight, simple, durable and comfortable, the Daylite is well-loved for a reason.
However, the damage to the spacecraft has rendered unusable the original scheme for obtaining spacecraft attitude solutions. By mid July, ground station operators had regained full control of the satellite and scientific operations were initiated at that time. Attempts at communicating with the satellite were unsuccessful until a surprised ground crew received a short transmission on on June 2. (It later turned out that the solar paddle was still attached to the spacecraft but only through some cable bundles). Images from a video system on the rocket seemed to indicate that ALEXIS has been severely damaged during launch with one of the 4 solar panels breaking away from its mounting. ALEXIS satellite was launched by a Pegasus booster into a 400 nautical mile, 70 degree inclination orbit on April 25, more » 1993. The spacecraft is controlled exclusively from a ground station located at Los Alamos. The ALEXIS satellite contains the two experiments: the ALEXIS telescope array, (which consists of six EUV/ultrasoft x-ray telescopes utilizing multilayer mirrors, each with a 33 degree field-of-view), and a VHF ionospheric experiment called Blackbeard. The Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite is Los Alamos' first attempt at building and flying a low cost, rapid development, technology demonstration and scientific space mission. ALEXIS was originally designed to be a high risk, single string. Now 4 years later is still collecting more than 100 MB of mission data per day. Science operations with the two onboard experiments began at that time. By late July, full satellite operations had been restored through the implementation of new procedures for attitude control. Due to damage sustained at the time of launch, ground controllers did not make contact with the satellite until late June.
The 113-kg Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite was launched from the fourth flight of Pegasus on 25 April, 1993 into a 750 x 850 km, 70 degree inclination orbit.
