Comments (37) Added to My StoriesA 'space yacht' propelled only by sunlight particles bouncing off its kite-shaped sails is to launch next month.
A rocket carrying the Japanese craft will blast off from Tanegashima Space Center on May 18.
Once in space the short cylindrical pod will separate from the rocket spinning up to 20 times a minute. This will help it to unfold its flexible 46ft sail, which is thinner than a human hair.
Ikaros will harness the power of the Sun using a 46ft sail that is thinner than a human hair The square shaped sail is equipped with thin-film
solar cells and will use resistance created by the Sun's energy in much the same way as wind propels a yacht through water. This will provide
it with enough thrust to hover and rotate.'It is a hybrid technology of electricity and pressure', Japanese Space Agency expert Yuichi Tsuda
said. 'Solar sails are the technology that realises space travel without fuel as long as we have sunlight. The availability of electricity would
enable us to navigate farther and more effectively in the solar system.'
More... 
Blink and you miss it: Shuttle Atlantis and space station pass in front of the Sun Scientists will steer the Ikaros by changing the angle
at which sunlight particles bounce off the silver-coloured sail. During a six-month mission they will head towards our sister planet Venus.
If this is a success Jaxa are planning further missions to the red giant Jupiter and Trojan using sails more than twice as the size of the Ikaros.
The space yacht will unfurl its solar sail several weeks after launch before heading to Venus
The £35million Ikaros will be the first use of such technology in deep space. Past experiments have limited crafts to orbits around Earth.
A Jaxa spokesman said: 'This will be the world's first solar powered sail craft employing both photon propulsion and thin film power generation
during its interplanetary cruise.'
It's name is an acronym for Interplanetary Kite-craft Accelerated by Radiation of the Sun. It also alludes to the Greek mythic hero Icarus
who flew too close to the Sun and fell into the sea.
The space yacht's sail will be deployed and kept flat by its spinning motion'Unlike the mythical Icarus, this Ikaros will not crash,' Mr Tsuda said.
Japan has become a major player in the space industry in recent years. In 2008 they installed a £1billion laboratory on board the International
Space Station.The space agency has proposed that the Japanese government send a wheeled robot to the moon in five years and build the world's first lunar base by 2020.Under the plan, the robot's tasks would include setting up an observation device, gathering geological samples and sending data back to Earth. The robot would also set up solar panels to generate energy.
This would cost Japan around £1billion over the next 10 years. Solar PV and Thermal Classes State of the art Training facility

Adrian ... can I add a few more ... the retrograde force (hopefully produced by the sail) will progressively destroy the angular momentum so that it
is not preserved, merely modified. And g "sun" will increase four fold when at half the distance between sun and earth so this satellite is in for an adventurous journey. The problem with stabilizing it in space ? ... the solar wind exerts a pressure on the sails. The centre of that pressure does
not necessarily pass through the CG so there is a net rotational force that will twist the sail and the satellite. Gyros can maintain give a platform a reference to the "fixed" stars but cannot longterm stabilize directly because you are straight into precession and all those problems. To stop that rotation would require a continuous counter torque that could (only?) be produced by a reaction engine (a mini-ion drive perhaps?). But all that destroys what seems to be presented as a simple concept so I wonder how they do it?

- Paul Townsend, West Bromwich, 01/5/2010 20:30
Jim- Not being a rocket scientist I'm only speculating now, but stabilization is usually done with gyros in satellites so this may be the same here.
The outward force as you correctly point out would appear to push the probe away from the sun. However, as an educated guess, the outward component of the force force like the side component would be very small. This would mean that gravity would dominate in the fight whereas the sideways component is completely unbalanced thus slowing the probe and increasing the effect of the gravitational component. Think of how a helicopter moves forward by pushing the air down and back at the same time. More thrust down than back and the helicopter flies forward but if
the balance is shifted then the helicopter flies forward faster but loses height slowly as well. It is for this reason that the inner planets are probably more suitable than say Mars which would require a much larger accelerating force in both directions.
- Adrian, Nottingham, 01/5/2010 20:13
Adrian ... if you slow the satellite relative to earth orbit then it will migrate into a lower solar orbit ... as you explain. But ... how do you stabilize the craft to present the sail at the correct angle (and stop the whole thing rotating about an axis) and on top of that ... the force excerted by the solar wind on the sail will have at least two components - one hopefully retrograde to the immediate orbit velocity (to slow down the unit) but the other
will be radially outwards from the sun accelerating the unit away from the sun. Will that radial force help or hinder?

jim, ventnor, UK, 01/5/2010 16:43
Sorry I realized my mistake. To make the probe fly on a trajectory to Venus what you need to do is accelerate in a retrograde direction to earth.
This in effect reduces your angular velocity which allows gravity to pull you towards the sun. The acceleration is in a sense a decelerating force with respect to the motion of the planets. Only on earth would the probe appear to accelerate away but in the direction from which we came. This would need the solar sail set at an oblique angle as I mentioned before. As angular momentum is conserved, as the probe moves nearer the sun its
"speed" will increase matching that of Venus, countering the acceleration in the opposite direction.
- Adrian, Nottingham, 30/4/2010 17:18 wouldn't they be better off aiming for a planet away from us and the sun

Posted In: R&D Daily Solar Energy Spacecraft By Jeremy Hsu, Space.com writer Monday, May 17, 2010
An ambitious solar sail mission designed by
Japan
is poised for launch tomorrow could become the first successful mission powered solely by sunlight,
but that's not all. The spacecraft is also aimed at Venus and beyond, and could pave the way for a future hybrid space engine.The solar sail will hitch a ride aboard an H-2A rocket slated for launch on Monday (Tuesday local time) from Japan's
Tanegashima
Space
Center
. That rocket carries the main mission of the Japan Aerospace Exploration Agency (JAXA), the Venus Climate Orbiter called Akatsuki — which means "Dawn" in Japanese.
A handout graphic designed image released from the Japan Aerospace Exploration Agency (JAXA) shows what the Japanese satellite Ikaros might look like in space.
Japan
is to launch a "space yacht" propelled by solar particles that bounce off its kite-shaped sails. But only Akatsuki has a planned meet-up with Venus, even though the sail — called Ikaros (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) — will also launch along the same trajectory toward the mysterious planet. "This will be the world's first solar powered sail craft employing both photon propulsion and thin film solar power generation during its interplanetary cruise," said a JAXA mission website. Venus would mark just a six-month pit stop for the solar sail during a three-year trek toward the far side of the sun. "To me it's a very bold activity to be conducting a technology test like this on an interplanetary mission," said Louis Friedman, an executive director of the Planetary Society in
Pasadena, Calif.
"I think it shows a lot of foresight on their part."
Past solar sail demonstrations have fallen short of achieving actual solar-propelled spaceflight, but that certainly has not stopped JAXA from planning an ambitious technological debut. Even Ikaros itself represents just a stepping stone to a "hybrid" space engine that incorporates solar sail technology, mission planners have said. Space hybrid vehicle The kite-shaped Ikaros relies upon the pressure of sunlight for propulsion, but it also carries thin film solar cells built within its sail. Such cells could generate electricity from the same sunlight pushing the solar sail along. That won't do much good by itself for a solar sail without an engine. But JAXA hopes that the power-gathering demonstration could eventually lead to spacecraft with ion-propulsion engines that draw electricity from solar cells and also take advantage of solar sail propulsion — a hybrid propulsion system. "They want to ultimately have a solar electric [ion propulsion] and solar sail vehicle that would be used for outer planetary missions," Friedman told SPACE.com.

4) Mathematics across the middle passage: Africanisms in American information technology
In the 1940s a debate raged between Melville Herskovits, who had documented the cultural retention of African traditions in the Americas, and E. Franklin Frazier, who argued that slavery had caused American blacks to be "stripped of their social heritage." Phillips (1990), reviewing this debate and its contemporary legacy, suggests a synthesis, noting that in addition to Africanisms among blacks, there are African cultural influences among white Americans, non-African cultural legacies of slavery among black Americans, and various syncretic mixtures of all three. Phillips' interest in de-racializing cultural heritage is particularly appropriate to the history of information technology, where such mixtures can thrive, recombine, and mutate in ways unpredicted by static social codes.
| Figure 7 shows an iron drill bit created around 1821 by Old Solomon, a "Negro blacksmith" in Natchitoches Parish, Lousianna. Christian (1972:23) notes that this double helix is "reminiscent of a piece of sculpture out of African ancestor worship," and indeed the geographic areas that Christian notes as origins for most slaves brought for iron work -- from present day Benin to Angola -- do have helical sculptures; usually in reference to the umbilical cord as a symbol of life (e.g. Swiderski 1970 fig 12). |

What would such cultural and technological syncretism mean to the enslaved blacksmith who created this? Under such circumstances survival itself is an act of resistance, and this is true not only
for physical survival but cultural and technological as well. Taking a line from poet Audre Lourde, "never meant to survive" became the title for Aimee Sand's interview with Evelynn Hammonds, a description of Hammond's experience as a black physics graduate student at MIT. In his aptly titled essay, "Tools of the Spirit," Alton Pollard (1996:1-2) reflects on Africanisms in American slavery as a survival strategy:
It is of course a given that the demeaned and oppressed will develop strategies of subversion, resistance, even armed combat against those who persecute them. But always, beyond the immediate goals of liberation, they also strive to create other images -- cultural signposts, hope-filled intimations of a more just and humane world.Africanisms in American culture include many of the indigenous African technologies, such as waveform representations in textiles, numeric and symbolic doubling, scaling geometries in hairstyles,
and animist concepts of spiritual energy embedded in artifice (contrary to the western stereotype that animism is "nature worship"). If we examine the work of African-American scientists such as Benjamin Banneker, George Washington Carver, and Ernest Everett Just, we can often see possibilties for African cultural survivals in their technological work (Eglash 1995, 1997b). Ernest Everett Just (1883-1941), for example, is often cited in social studies of science because his social critique of the "master-slave" model for nucleus-cytoplasm interactions motivated his discovery of cytoplasm dynamics (e.g. Hess 1994). But these descriptions often overlook the possibility of African influence. Just grew up on James Island, South Carolina, where the black population still spoke Gullah (a mixture of English and west African languages), and had retained a wide variety of African customs and traditions (Manning 1983:15). Just's work was not just a critique of nucleus versus cytoplasm, but also digital versus analog: information transmitted by the genetic code versus information transmitted by the propagation of biochemical waves through the cell. In his technical writing Just used an analogy to music to describe how such analog waveforms could carry information. In his private communication to anthropologists (including Melville Herskovits, who came to Howard University at Just's invitation), Just remarked that music offered the best case for African cultural retentions in American blacks. There was a strong resemblance between the information waves in Just's scientific models and those he heard echoing across the middle passage.
5) Information technologies and African American identity in the modern era
Just's work did not remain isolated; G. Ross Henderson brought his framework to the scientific community that would later become General Systems Theory. This is part of a longer history in which more subtle influences from black culture were also at work, informing, contesting, and appropriating mainstream technologies. Historian Rayvon Fouché, for example, has described the ways in which black inventors used both social and technical strategies to get around Jim Crow restrictions from patent rights. Fouché notes that Granville Woods (1856-1910), inventor of the Synchronous Multiplex Railway Telegraph, developed expertise in patent interference claims to counter corporate attempts to use his race to cheat on contracts. Technology often served as a sign of white priviledge, and it is no surprise that black fiction often played with new visions of technology. In 1938 African American journalist George Schuyler published Black Empire, a science fiction in which a black revolt of "intellectuals, scientists, and engineers" includes a black biologist named "Ransom Just." Even black literature not typically considered science fiction, such as Ellison's Invisible Man or Bambara's Salt Eaters, often have strong technological themes.
Science fiction is also credited by some black scientists as playing a pivotal role in their dedication to technological careers. Derek Harris, the president of the first black-owned computer company, recalled that the Mission Impossible character "Barney Collier," an African American electronics wizard, was a major influence in his childhood fascination with technology. There is, of course, a big difference between black science fiction, and black characters in science fiction written by white authors. Samuel Delany makes this point in an interview where he rejects the figures of the "Rastas"
in Gibson's Neuromancer as providing an oppositional political stance (Dery 1994:194-197). And it is worth keeping in mind how those ficitional roles are filled. During the 1960s, for example, we saw black technological characters restricted to the roles of "communications officer" (read secretary?) -- as in the case of Greg Morris' Barney Collier, Ivan Dixon's "Sgt. Ivan Kinchloe" in Hogan's Heros, and Nichelle Nichols' "Lieutenant Uhura" in Star Trek. But when Nichols announced that she was planning to leave the show at the end of the first season, she was confronted by none other than Dr. Martin Luther King Jr., who told her "you cannot leave… you have opened a door that must not be allowed to close." Decades later, the first African-American woman in space, Dr. Mae Jemison, credited Nichols with her early aspirations towards space.
While the intertwinings between black popular culture, science, and science fiction are an important part of this story (and typically disregarded by the "minorities in science education" efforts), the success of African Americans in information technology is hardly a matter of easy dreaming. Best known is probably John P. Moon, a silicon valley engineer who dedicated years of work to studying memory storage systems, culminating in what is still the most popular transportable storage medium in existance today, the 3.5" floppy disk. At the other end of the high-tech/lowtech spectrum, black appropriations of information technology by members of economically disadvantaged communities have often utilized a bricollage of cast-off hardware, as described in this 1995 message from
a DJ at KPOO radio in San Francisco to the listserv for the National Urban League:
