SMART-1’s journey to the Moon is now fully under way. After the initial test firing of the ion engine in Earth orbit, there was a series of further tests to measure the engine’s behaviour. These have now been completed.

At this time, the engine is being fired as planned for about 90% of each orbit to gradually raise it away from the Earth on its spiralling trip out to the Moon. The engine can’t be fired during certain parts of the orbit when the spacecraft is in the shadow of the Earth, because then the solar arrays will not generate electrical power.

Since its launch, the size of the spacecraft orbit has already increased by 500 kilometres and all systems on-board are functioning well. “As a newborn in space, SMART-1 is progressively waking up to its new environment,” said Bernard Foing, ESA’s SMART-1 Project Scientist. “Like caring parents, ESA engineers and scientists are monitoring its position, temperature and health signals around the clock.”

SMART-1’s scientific instruments are also in good health, and have been checked in what is called the ‘Pre-commissioning’ phase. Andrea Marini, ESA’s SMART-1 Payload Engineer said: “After these years of development and testing of the SMART-1 payload, what an emotional time it has been to be able to communicate with the instruments, and receive their signals as expected.”

As part of its mission objectives, SMART-1 is collecting interesting data about the behaviour of the ion engine during its passages (or 'transits') in and out of the Earth’s Van Allen radiation belts, which will continue for the next two months. These radiation belts surround the Earth with a stormy environment of energetic particles that could affect the electronic systems and computers on board the spacecraft.

The engine, however, is already working well in these transits. When SMART-1 is safely out of the Van Allen belts also its instruments will be able to operate fully and provide more sophisticated data. They will be calibrated to improve their vision in the visible, infrared and X-ray wavelengths, and to test further the technologies on board this clever space baby.

30 September
The launch of ESA’s SMART-1 spacecraft to the Moon onboard an Ariane 5 rocket from Kourou, French Guiana successfully took place on 28 September at 1 hour 14 Central European Summer Time. The satellite separated from the launcher 42 minutes after lift-off and was placed into a geostationary transfer orbit with 654 km perigee and 35.885 km apogee. First signals of the satellite were received 2 minutes later at 1 hour 58 over the Perth ground station in Western Australia. The solar arrays had both been deployed by 2 hours 24 local time. Telemetry received confirms a nominal satellite performance in all subsystems. The first Electric Propulsion Firing is planned for tomorrow, 30 September.

28 September
Separation of SMART-1 41:31 minutes into the flight.

Arianespace Flight 162 has lifted off from the Spaceport in French Guiana, carrying a three-satellite payload, including ESA's SMART-1. Its fellow passengers are the Eutelsat e-BIRD broadband services satellite, and the Indian Space Research Organisation's INSAT-3E telecommunications/video broadcast platform

01:17 CEST. Lift-off of Ariane 5 with SMART-1.

27 September
23:00 CEST. Everything is fine in the main control room of ESOC in Darmstadt. All systems are green - we are expecting the launch as planned. The SMART-1 flight team is relaxed, in the starting blocks, waiting for the launch of SMART-1 from Kourou.

16:00 CEST. Final preparations for tonight's liftoff of Flight 162 are nearly complete following yesterday's transfer of the Ariane 5 to the launch zone, reports Arianespace.

SMART-1 factsheet

Testing solar-electric propulsion and other deep-space technologies

Name SMART stands for Small Missions for Advanced Research in Technology.  

Description SMART-1 is the first of ESA’s Small Missions for Advanced Research in Technology. It is heading for the Moon using solar-electric propulsion and carrying a battery of miniaturised instruments. As well as testing new technology, SMART-1 will make the first comprehensive inventory of key chemical elements in the lunar surface. It will also investigate the theory that the Moon was formed following the violent collision of a smaller planet with Earth, four and a half thousand million years ago.


Launched 27 September 2003


Status En route for the moon.


Notes SMART-1 is the first European spacecraft to travel to and orbit around the Moon.

This is only the second time that ion propulsion has been used as a mission's primary propulsion system (the first was NASA's Deep Space 1 probe launched in October 1998).

SMART-1 will look for water (in the form of ice) on the Moon.

To save precious fuel, SMART-1 will use 'celestial mechanics', that is, tricks like 'Moon resonances' and swing-bys.
