Europe's first moon mission blasts off successfully

Anyone have any more details on the mission or an ESA website we can monitor during the upcoming months for news of its progress?

Anyone know what the tasks are for the Indian and French satelites that are aboard?

Do you think this new solar-charged electrical propulsion is the first stepping stone to a manned flight to Mars?





Europe's first moon mission blasts off

KOUROU, French Guiana (Reuters) --Europe's first mission to the moon blasted off late on Saturday aboard a European Ariane rocket, space officials said.

The Ariane-5 rocket carrying the SMART-1 moon exploration probe and two commercial satellites blasted off at 8.14 p.m. (2314 GMT) from the European Space Agency (ESA) launch center at Kourou, in French Guiana on the northeast coast of South America.

Forty-one minutes after launch, the rocket released SMART-1 into space to begin a 15-month journey to reach lunar orbit. The 370 kg (815 lb) probe will scan the moon for up to 30 months.

SMART-1 will cover a distance of 100 million kilometers (62 million miles) to reach the moon with only 60 liters of fuel," Giuseppe RACCA, ESA Project Manager said before the launch.

"The main form of propulsion will be electric, charged by the satellite's solar panels," he said.

The probe will provide data on the still uncertain origin of the moon and has been described by ESA as an important instrument "to unraveling some of the secrets of our neighboring world."

"Thirty-five years after Apollo and the Russian missions, there remains much we don't know about the moon," David Southwood, ESA's Director of Scientific Programs, told a news conference in Kourou.

"With SMART-1 we can test propulsion in deep-space orbit. The next step, I hope, will be a Mars mission," he said.

ESA has hailed SMART-1 as an example of a 'faster, better, cheaper' mission costing only 110 million euros ($126 million) -- about one-fifth of a major ESA science mission. It is designed to operate in lunar orbit for up to 30 months.

The rocket also carries an INSAT 3-E satellite for the Indian Space Research Organization and e-bird for the Paris-based satellite operator Eutelsat.

Originally scheduled for launch earlier in the year, the mission was postponed due to technical problems aboard INSAT 3-E.

Well, most recent informations are to be found on ESA's own website

Hmm, I scanned through the ESA website on SMART but didn't find any information about the Indian and French satelites. Wonder if this is similar to when the US makes no mention of details of satelites in Shuttle payloads that have a set of military objectives.

After reading the details about the ion propulsion technology, I have doubts about it ever being for manned space exploration. The cost savings in fuel would be offset by the extra costs for life support necessities for the extended travel time. Maybe when we have onboard food replicators like they do on the Enterprise it will be a viable technology for manned exploration.

It's a first step with an interesting technology. Not sure about decreased fuel requirements being offset by greater weight of life support equipment. Remember that rocket propelled vessels are under boost for a very short time. Ion propulsion could be applied almost continuously, though the available power may diminish as the distance to the sun increases.

The French satellite is obviously a (tele-)communication satellit, has at least a similar name like the others. (e-BIRDTM).
I think -and as far as I remember- it's the same with the Indian INSAT-3E.

The present first stage available has too little power to get to Mars or elsewhere with humans and supplies unless we use an ion engine. Options are to launch from ISS which might contaminate the International Space Station or design and build much more powerful first stages which may be dangerious or unreliable. In theory an ion engine is best for very long missions such as men to the Oort cloud, which might require a first stage a mile tall and 100 yards in diameter. Neil
