At the Service of Science / Rockot Multiple Orbit Mission hits different Orbits

Bremen/Germany, 13 May 2003. At the end of June 2003, Eurockot Launch Services, Bremen, will perform the Multiple Orbit Mission from Plesetsk Cosmodrome in Northern Russia. Eurockot will launch a total of eight scientific micro- and nano-satellites for different agencies and institutes by deploying them into an elliptical as well as into a sun-synchronous orbit. Additionally a mock-up of the Russian MONITOR satellite will be mounted on Breeze. Eurockot will perform this mission based on the multiple re-ignition capability of its Breeze upper stage. This will be the first sun-synchronous mission (SSO) of Rockot. The flight will initially deploy one satellite into an elliptical orbit. After another impulse maneuver of the main engine, Breeze will then deploy seven further spacecraft into a sun-synchronous orbit at pre-determined intervals.

Satellites and their Operators

The Czech MIMOSA satellite, with a total mass of 66 kg will be the first satellite to be deployed during the Multiple Orbit Mission, going into an elliptical orbit. MIMOSA, the acronym for MIcroMeasurements Of Satellite Acceleration, will provide new data on the density of the upper atmosphere using the highly sensitive MACEK accelerometer. The orbit will have an apogee of 820 km and a perigee altitude of 320 km. 

Following the release of MIMOSA, Breeze will re-ignite its main engine in the apogee to reach a sun-synchronous orbit (SSO) of 820 km altitude.

The Canadian Space Agency`s (CSA) satellite MOST will be the first to be released. Its mass is 51,3 kg. MOST (Microvariability & Oscillations of STars) will be carryingCanada's first space telescope, the result of a co-operative Canadian scientific partnership. The telescope will help to set a limit on the age of the Universe and probe the properties of planets around other stars.

After deploying the prime payloads MIMOSA and MOST, 6 nano-satellites will be deployed at pre-determined intervals into an SSO as well.

Two student-built educational nano satellites, namely CubeSat XI of the University of Tokyo Intelligent Space Systems Laboratory (ISSL) and CUTE-I of the Tokyo Institute of Technology Laboratory for Space Systems (LSS) will be released first.

Following these deployment maneuvers the four NLS-1/2 satellites will be deployed. The University of Toronto Institute for Aerospace Studies UTIAS leads the Nanosatellite Launch System NLS-1/2. NLS-1 combines three 1 kg satellites using a launch tube. These satellites will be operated by different institutes, namely CanX-1 by the University of Toronto, Canada; AAU Cubesat by Aalborg University, Denmark and DTUsat by the Danish Technical University. The main purpose of the satellites is star imaging. Next will be the NLS-2 satellite with QuakeSat of the US QuakeFinder Institute. QuakeSat weighs 3 kg and is also accommodated in a launch tube. The satellite’s mission is an earthquake detection experiment. 

The mockup of Monitor, the Khrunichev-designed Russian earth observation satellite, will transmit mission profile simulation data during its entire flight. This mockup will remain on the Breeze upper stage and will also de-orbit with it. For this final maneuver the upper stage will be re-ignited once more.
