Solar Sail Fails Again

Re:This will probably get bad press...

The full text of the quote in question is:

"We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."

It is from an address given at Rice University in Houston (where Mission Control is located) on September 12, 1962. This is also the speech that contains the phrase "We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people."

I look up to Kennedy because he was so truly enthusiastic about the space program like no President since has had the guts to be.

The True Importance of the Solar Sail

[Buran]

While this mission was not a success in that the spacecraft did not separate from the third stage of the launcher -- currently, it is believed that the separation command was overridden by the control computers due to excessive vibration in the vehicle, which is by design -- it is a success in other, more important ways.

First, it helps to bring the concept of the solar sail as a valid idea to the public eye. Solar sails have been something of a mainstay in some science fiction series as a way of getting to other planets and have even shown up in some popular sci-fi series (one episode of Deep Space Nine, for instance, showed an old Bajoran solar sail vessel, albeit with far too little sail area to accelerate as "fast" as more serious concepts would). However, other more conventional systems (by far the chemical rocket, but followed to a lesser extent by nuclear rockets (does anyone recall the NERVA program that might have sent humans to Mars by the 1980s?) and ion propulsion: how many of you knew that the term TIE Fighter from Star Wars stands for "Twin Ion Engine"? Star Wars never stated what gas was used in those systems, but the gas that has been used in the Deep Space 1 mission and in the Artemis commercial spacecraft. Now that the Planetary Society, which is a well-respected organization, has attempted to actually fly a solar sail, the public will become aware of the possibility.

It helps to bring the existence of such organizations into the spotlight as well. The Planetary Society has been active for decades -- it was founded by Carl Sagan -- and there are others, including what is perhaps the best-known of these groups: the National Space Society. Others, far less well known, exist, ranging from fan clubs for shows like Babylon 5 (which I applaud for showing what space exploration will be like in perhaps a few decades once we've gotten the hang of building spacecraft with rotating gravity sections to avoid the problems that long stays in microgravity cause) to other grassroots groups that give more or less anonymously (that is, they don't get press coverage) to serious efforts.

And it also helps to give people like us the idea that we might eventually actually get to go to space ourselves. If someone can spend $20 million for a ride on a Soyuz capsule, and if a non-profit organization can launch a solar sail, then what could happen in fifty years?

This was, like Apollo 13, a "successful failure".
