ESA Looking for People to go to Mars. Are You Such a Person?

Astrobiology Magazine has a great article on the European Space Agency looking to recruit people for a mission to Mars. They want to send a manned mission to search for biological evidence that Mars once had life.

They feel there may be a wealth of archaeological information to be had that robotic explorers are unable to search for.

The people chosen to participate will have to be sociologically evaluated. Because they will be on board a two year round trip.

This is a big ask upon any individual - the waiting time in a small space capsule while it made such a journey is very daunting to say the least. Once there, the work begins in earnest, but the depressing thought of an equally long journey back must be horrendous. For the complete article; click the link below.

Europe plans to build world's biggest X-ray telescope

This is from: SPACEFLIGHT NOW - an online magazine of current space exploration news

A half-year after the European Space Agency formally prioritized high-energy astrophysics for its next flagship-class science mission, officials announced Friday the selection of a European-led X-ray observatory named Athena for launch in 2028.

The huge telescope will replace ESA's XMM-Newton mission and NASA's Chandra X-ray Observatory, collecting data on the interplay between matter and black holes, halos of enigmatic hot gas enveloping faraway galaxies, distant gamma-ray bursts, and other phenomena.


Athena will see objects fainter than XMM-Newton or Chandra, and it is the only X-ray telescope in its class slated for launch in the 2020s, ensuring high demand for Athena's data haul, according to scientists.

The telescope will launch on a heavy-lifting rocket, possibly Europe's Ariane 5, and fly to the gravity-stable L2 Lagrange point a million miles from Earth for a five-year mission.

Athena will weigh about five metric tons, or about 11,000 pounds, at launch. Its telescope will measure about 12 meters, or 39 feet, long with ultra-lightweight silicon pore optics, a new technology comprising stacks of silicon wafers to reflect high-energy X-ray light to the mission's two instruments.

Missions like Athena must launch into space to see the universe in X-rays, which are absorbed by Earth's atmosphere, rendering observations from the ground impossible.

Athena will look back in time to observe how galaxies and galactic clusters assembled a few billion years after the Big Bang, according to the mission's backers.

The telescope will also resolve the flows of matter falling into black holes, contribute to exoplanet research, and survey the wider universe to map large-scale cosmic structures.

"Athena will be a state-of-the-art observatory that will provide a significant leap forward in scientific capabilities compared with previous X-ray missions, and will address fundamental open questions in astrophysics," said Alvaro Gimenez, ESA's director of science and robotic exploration. "Its selection ensures that Europe's success in the field of X-ray astronomy is maintained far beyond the lifetime of our flagship observatory XMM-Newton."

Officials announced in November that the next two large-class missions in Europe's Cosmic Vision program would be an X-ray telescope and a mission to confirm the existence of gravitational waves.
The Cosmic Vision program is a strategic architecture for the selection of Europe's space science missions through a judicious process involving proposals, reviews and recommendations by the European research community.

But the November decision in favor of X-ray and gravity wave missions did not come with a selection of specific mission concepts.

For the first large-class, or L1, Cosmic Vision mission, ESA is working on an orbiter to be launched to Jupiter in June 2022.

ESA's Science Program Committee last week signed off on the Athena mission for the L2 opportunity, and an endorsement of a concept for the L3 gravity wave research mission will come in 2020, with launch to follow in 2034.

Athena was the only proposal submitted for consideration by the committee, officials said.
Next comes detailed study and definition phases to mature technologies required for the Athena mission.
ESA will also begin negotiations with potential partners, such as the United States and Japan, to contribute to the Athena mission. NASA officials have already stated their interest to provide components for Athena's scientific sensors.

European Space Agency officials will meet again around 2019 for formal adoption of the Athena mission, setting a budget, plan and other details before industry begins construction of the spacecraft and its instruments.

Another Look at Orion Spacecraft at NASA



The Orion spacecraft is the new big project under development. The US government had cold feet about expense for some time and probably still does - understandably. The costs of building such a spacecraft must be colossal and the US electorate would want their taxes spent elsewhere. 

However, funding from private enterprise could be the answer as many firms re-invest in such a project to get their own space ideas into the cosmos and onto Mars. Private enterprise is beginning to find advantages in space exploration.

Warp Drive Theory - Is it Fantasy or could it be real?


Now that private funded firms are looking at ways to travel in space, there are all sorts of new innovations and speculative theories getting air time from sponsors. In the past governments were very careful on what projects they would adopt and pursue. With private enterprise, the inventors have a wider range of organisations to take their inventions to. They have more hits at trying to sell ideas. As government spending is geared more towards getting vehicles out into space as cheaply as possible, private enterprise began hitching rides with CubeSats and other innovations, but soon, more companies will look at funding space vehicles into the cosmos and ideas of travelling further into space and quicker. Warp drive is now being taken more seriously even though it is still theoretical for the moment. Ships are actually being put to design.

NASA's Design for a New Warp Drive Monster - Star Trek Become a Reality.

I was spellbound by this piece from CNN news. I have pasted it here because there is so much info I would like to keep on the blog. This is a mega Wow!



(CNN) -- Thanks to a NASA physicist, the notion of warp speed might just travel out of sci-fi and into the real world.

NASA's Harold White has been working since 2010 to develop a warp drive that will allow spacecraft to travel at speeds faster than light -- 186,000 miles per second.

White, who heads NASA's Advanced Propulsion Team, spoke about his conceptual starship at a conference last fall. But interest in his project reached a new level this week when he unveiled images of what the craft might look like.

Created by artist Mark Rademaker, who based them on White's designs, the images show a technologically detailed spacecraft that wouldn't look out of place in a "Star Trek" movie. Rademaker says creating them took more than 1,600 hours.

For now, warp speed is only possible in TV and movies, with both "Star Trek" and "Star Wars" referencing an idea that was completely speculative at the time. White has fittingly named the concept spacecraft IXS Enterprise, for the starship famously piloted by Captain James T. Kirk in the "Star Trek" TV series and movies.

At the SpaceVision 2013 Space Conference last November in Phoenix, White talked about his design, the concepts behind it and the progress that's been made in warp-drive development over the decades. He discussed the the idea of a "space warp," a loophole in the theory of general relativity that would allow for massive distances to be travelled very quickly, reducing travel times from thousands of years to days.

In his speech, White described space warps as faraway galaxies that can bend light around them. They work on the principle of bending space both in front of and behind a spacecraft. This would essentially allow for the empty space behind the craft to expand, both pushing and pulling it forward at the same time. The concept is similar to that of an escalator or moving walkway.

"There's no speed limit on the expansion and contraction of space," White said at the conference. "You can actually find a way to get around what I like to call the 11th commandment: Thou shall not exceed the speed of light."

It's the idea of space warps that inspired physicist Miguel Alcubierre in 1994 to first theorizes a mathematical model of a warp drive that would be able to bend space and time. While studying Alcubierre's equations, White decided to design his own retooled version of the Alcubierre Drive. His recently unveiled design has much less empty space than the first concept model, increasing its efficiency.


The warp drive that White's team has been working on would literally transcend space, shortening the distance between two points and allowing the craft to break the speed of light. This would be a spaceship with no speed limit.

Because travel into space has been extremely limited due to existing means of propulsion, such technology could blow open the possibilities of space exploration. It could allow for the study of the farthest reaches of space, parts that scientists once considered unimaginable.

Although the technology to create the spacecraft or the warp the drive doesn't yet exist, the artistic renderings Rademaker created could potentially be a model of what's to come -- the first spacecraft to break the speed-of-light barrier and journey beyond our solar system.

In his design, White says he drew from Matthew Jeffries' 1965 sketches of the Enterprise from "Star Trek," saying parts of that the ship was mathematically correct. He worked with Rademaker and graphic designer Mike Okuda to update the math and produce what he believes to be a viable spacecraft.

According to NASA, there hasn't been any proof that a warp drive can exist, but the agency is experimenting nonetheless. Although the concept doesn't violate the laws of physics, that doesn't guarantee that it will work.

"We're starting to talk about what the next chapter for human space exploration going to be," White said at SpaceVision.

Exciting New SpaceX Ferry Vehicle.

I read this exciting new article in the Los Angeles Times. It is a new innovative space transporter for astronauts and it can take personnel to space stations. This space vehicle is called SpaceX and it can be used again and again - a low-cost ferry service from Earth to the space station. It can also land, upon return to Earth, touching down under its own rockets like a helicopter can land.
This new craft is very exciting as the U.S. looks for ways of cutting costs to send its astronauts and scientists into space. SpaceX is a Dragon Capsule with Falcon 9 rockets attached. It looks pretty basic, but then some of the expensive problems can often be eliminated with simple ideas. If it works and it works well; why not go for it. The sky is never the limit for these people who have left footprints on the moon.
We wanted to take a big step in technology," Musk said. "It really takes things to the next level."
Before a massive white curtain dropped to unveil the capsule, a fast-moving, animated video showed the white, cone-shaped spaceship blasting into orbit atop a rocket. It zoomed to the space station, docked with it, then returned to Earth, gently touching down under its own rocket power.
"That's how a 21st-century spaceship should land," Musk said to a cheering crowd, noting that it would have the landing accuracy of a helicopter.

The capsule, dubbed Dragon V2, is designed to carry seven people and, unlike the Apollo craft, will be reusable, he said. The company expects to make its first manned test flight by the end of 2016.
Having the ability to reuse the spacecraft is a big factor, Musk said, because it will cut costs.
"As long as we continue to throw away rockets and spacecraft, we will never truly have access to space," he said. "It'll always be incredibly expensive."
To emphasize the point, Musk asked the audience to imagine what would happen if a commercial jetliner were thrown away after each flight. Very few people would be able to afford the trip, he said.
Since NASA's fleet of space shuttles was retired in 2011, the space agency has had no way to get its astronauts to the space station other than paying the Russian government $71 million a seat.
The arrangement with Russia, though, is showing some strain. This month, Russian Deputy Prime Minister Dmitry Rogozin suggested that his nation might halt U.S. access to its launch vehicles and may use the International Space Station without American participation.


From the outset three years ago, NASA wanted to turn over-shuttling operations to American industry. The agency has handed out hundreds of millions of dollars in seed money to private companies to develop launch vehicles to take astronauts into outer space by 2017.
The NASA contracts set off a private space race. SpaceX has already sent a version of its craft into orbit in outer space and had it return intact.
SpaceX builds its Dragon capsules and Falcon 9 rockets in a vast complex in Hawthorne, where fuselage sections for Boeing's 747 jumbo jets once were built. The company is expanding its complex, near Los Angeles International Airport, and has more than 3,000 employees.

At the time of the test in 2011, the Dragon capsule was empty, but it was a technological and financial feat that had been accomplished before only by government entities. The capsule has since delivered cargo to the space station three times.
SpaceX, short for Space Exploration Technologies Corp., has a $1.6-billion contract with NASA for a total of 12 deliveries.
The company won additional contracts from the space agency worth more than $500 million to develop its hardware to be astronaut-ready.
Others with contracts were Boeing Co., which has built nearly every manned spacecraft in U.S. history, and Sierra Nevada Corp. of Sparks, Nev., which is building a space plane that closely resembles a mini space shuttle.
SpaceX's Dragon V2 spacecraft looks like a sleek, modern-day version of the Apollo capsules that astronauts used in trips to the moon in the 1960s. Those capsules splashed down in the ocean and couldn't be reused.

Swedish Scientists of Gothenburg University Identify that Water Once Flowed on Mars



New research has suggested that water was flowing across the surface of Mars some 200,000 years ago. The nature of rock formations in a Mars crater suggests the sediment deposits and channels it contained were formed by ‘recent’ flowing water.
Swedish scientists from the Department of Earth Sciences at the University of Gothenburg identified“Very young …and well-preserved deposits of water bearing debris flows in a mid-latitude crater on Mars,”according to the study published in the journal Icarus. 

It was previously estimated that liquid water flowed across the Red Planet during its last ‘ice-age’, some 400,000 years ago. However, the young age of the crater means the features signifying water must have appeared since. 

The scientists drew comparisons between the geomorphological land formations and the Norwegian archipelago of Svalbard. The crater had features of areas on earth where debris flow had caused material to be deposited by fast-flowing water. 

“Our fieldwork on Svalbard confirmed our interpretation of the Martian deposits,” stated Andreas Johnsson, a spokesperson for the research team. 

“Our study crater on Mars is far too young to have been influenced by the conditions that were prevalent then. This suggests that the meltwater-related processes that formed these deposits have been exceptionally effective also in more recent times,” said Johnsson. 

“If we find on Mars evidence for a second genesis, that changes everything,” Johnsson added. 

A debris flow takes place when liquid water soaks through debris lying on an incline to the point that it becomes saturated and heavy, causing it to descend down the incline. 

On earth, debris flow can result in material destruction and sometimes casualties, depending upon their severity. 

When the flow stops, new landforms are made, including lobate deposits and paired levees. It is these that Johnsson has identified on the planet. 

“Gullies are common on Mars, but the ones which have been studied previously are older, and the sediments where they have formed are associated with the most recent ice age. Our study crater on Mars is far too young to have been influenced by the conditions that were prevalent then,” Johnson said.

Exciting New Star Cluster Photos Taken by Nasa Hubble Space Telescope

Clip Taken From Independent Newspaper
NASA
Nasa has released a stunning image of a brightly coloured ancient cluster containing more than 100,000 stars captured by the Hubble Space Telescope.

This description suggests Messier believed M5 was a nebula, a cloud of dust, hydrogen and other gases, when developments in observation technology later revealed it was actually a cluster of stars.

Nasa said: “Though it appeared to Messier to be fuzzy and round and without stars, Messier 5 (M5) is now known to be a globular star cluster, 100,000 stars or more.”


NASAM5 is one of the oldest globulars and its stars are believed to be almost 13 billion years old, making it one of the oldest globulars to be associated with the Milky Way Galaxy.

“Even close to its dense core at the left, the cluster's aging red and blue giant stars and rejuvenated blue stragglers stand out in yellow and blue hues in the sharp color image”, Nasa added.



The Hubble Telescope was launched from the Kennedy Space Centre on 25 April, 1990 and celebrated its 24th year in orbit on Friday. The telescope's orbit outside of the Earth's atmosphere allows it to take high resolution images within almost no background light.

New Earth Type Planet Discoverd - Earth 2 Kelper - 186f

From Metro News

Earth 2.0 discovered, may be capable of supporting life

A planet bearing strikingly similar characteristics to Earth and potentially capable of supporting life has been discovered in the Milky Way.
Dubbed ‘Earth 2.0’, Kepler-186f is the closest match to our own planet ever discovered and renews hopes that life in outer space may be a reality.
Slightly bigger and colder than Earth, the planet is said to be in the ‘Goldilocks zone’ because it sits at just the right distance from its star where temperatures allow water, and therefore potentially life, to exist.
‘Kepler-186f is the first validated, Earth-size planet in the habitable zone of another star,’ said Elisa Quintana of the SETI Institute and Nasa’s Ames Research Center.
‘It has the right size and is at the right distance to have properties similar to our home planet.’
Dr Quintana is the lead author of a scientific paper detailing the planet’s discovery, 500 light years from Earth, in this week’s issue of the Science journal.
The group of scientists have been keeping watch over 150,000 stars in the universe looking out for slight drops in brightness when a planet passed in front, according to the New York Times.
Further analysis of the planet will now take place to determine whether indeed it does hold water.
Over 2,000 planets outside our own solar system have been found in the last 20 years but Kepler is particularly good news because the star it orbits is similar to 70 per cent of those in the Milky Way and therefore finding other similar planets is now a real possibility.

Life on Mars Search Continues



I love the report of the Martian Robot explorations that come from NASA in the quest to find life on Mars. This is a new report from the Space Reporter.

NASA’s Opportunity rover is celebrating ten years since it landed on Mars, on January 24, 2004. In the rover’s 24-mile journey from its landing site to the rim of Endeavour Crater, it has uncovered evidence that is helping to elucidate the early history of Mars. The latest findings have been analyzed by a team led by Opportunity Deputy Principal Investigator Ray Arvidson of Washington University.
According to a NASA statement, Opportunity has analyzed rocks older than any others encountered by the rover. The Opportunity team at NASA’s Jet Propulsion Laboratory employed an instrument on the Mars Reconnaissance Orbiter that is designed to map minerals on the Martian surface. This instrument, the Compact Reconnaissance Imaging Spectrometer for Mars, began scanning the vicinity of Opportunity in 2010, and detected the signature of a clay mineral called iron-rich smectite at a site on Endeavour’s rim known as Matijevic Hill.
 
The Opportunity team steered the rover in a loop, guided by the orbiter, until it arrived at the promising outcrop. There, Opportunity had the chance to study the smectite in its proper context and determine how its location and position in the Martian geological record relate to those of other minerals and rock layers.
 
Arvidson and team’s analysis of the new data indicates that the warmer, wetter conditions in which the iron-rich smectite formed existed before Endeavour Crater was gouged out approximately 4 billion years ago. This environment also predates acidic and oxidizing conditions represented in rocks previously studied by the rover. The environment would have been suitable for microbial life. The new research has been published in the January 24 issue of the journal Science.
 
Although Opportunity’s twin rover, Spirit, ceased to function in 2010, Opportunity is still working well in conjunction with the larger, newer Curiosity rover half a planet away. Both rovers are guided by data gathered by the Odyssey and Mars Reconnaissance orbiters.
 
I can't help wondering if some of the conditions that destroyed Mars might have been around the time when the believed meteorite hit Earth destroying the dinosaurs. Its only a thought, but maybe the solar system had a rain fall of meteorites many billion years ago along a scale more intense then we get at present.
 
Of course I'm no scientist and my dates could be way off and I'm sure NASA scientists have explored such a possibility. I will watch the continuous reports of the Martian exploration robots. Its very exciting stuff and I hope they find some fossil evidence of life, even if its the minutest form of life that once was.

European Space Agency's Rosetta spacecraft to be a Comet Chaser at 24,600mph

ESA Spacecraft to be woken for Big Mission

Report by Independent Newspaper



A spacecraft will begin one of the most daring missions ever attempted on Monday - landing on a comet which is hurtling through space at 24,600 mph.
As it is impossible for it to achieve the speed needed alone, the spacecraft has completed three flybys of Earth and one of Mars to build up pace using the planets' gravitational pulls.
Operating on solar energy alone, the spacecraft was placed into a deep sleep in mid-2011 in order to conserve energy as it cruised far away from the Sun’s gaze and out towards the orbit of Jupiter. It has been out of contact with Earth ever since.
At 10am on Monday, what the ESA is calling the ‘most important alarm clock in the solar system’ will sound to awaken the vessel. It will then take up to six hours for the vessel’s star trackers to warm up - only then can it attempt to reconnect with mission control on Darmstadt, Germany.
Due to Rosetta’s vast distance from Earth – just over 807 million kilometres – it will take 45 minutes for the signal to reach home, meaning controllers will be tentatively listening out for the signal between 17:30 and 18:30 GMT.
It is hoped that the Rosetta will finally catch up with the comet in August when it will spending a couple of months studying and mapping the 2.5 mile wide ball of ice and dust, before dropping a small robot on its surface to gather samples and take pictures.
European Space Agency project scientist Matt Taylor compared the mission to the film 'Armageddon’ - in which Bruce Willis’s character lands lands on an asteroid to to prevent it from destroying Earth.
“We look at comets as being a time capsule, they are relics from the beginning of the solar system,” added Mr Taylor, speaking to The Sunday Telegraph. “We felt we had to go to one.”
Fred Jansen, ESA’s Rosetta mission manager, added: “We’re very excited to have this important milestone in sight, but we’ll be anxious to assess the health of the spacecraft after Rosetta has spent nearly 10 years in space.”

Human Travel To Mars


More and more, people are looking at the notion of a manned expedition to Mars. Different scientific teams from all over the world are looking to Mars in the hope of finding evidence of past alien life. The concept of ship design to make the journey and the ideas of return continue to be thought about. It will not be long before someone take on the quest.

The Boundries are Limitless





We are beginning to branch of in all sorts of exciting directions with space exploration involving a multitude of projects. Soon these things will be open to more and more people with new ideas. There seems to be endless new boundaries to overcome, yet the prospect excites us. I believe it is in our instinct to go to the stars.


Soon everyday people from all sorts of mundane backgrounds will be involved with space. Not just people of universities. There will become new and increased needs for all sorts of workers. The sliding window is only ajar but slowly it get wider and more people will want to pass through the window of opportunity in the near future.

CubeSat Launch Initiative (CSLI.)

CubeSat Launch Initiative (CSLI.)


There are small remote-controlled research spacecraft known as CubeSats. They are nano-satellites. These little cube-shaped outposts get released into orbit and are no more than half the size of a shoebox. This is a U-1 CubeSat but they can be clipped together. Two or three together may contain more monitoring and comlinks. Thus we get U-2 or U-3, depending on how many are clipped together.

Multiple CubeSats are stored in a large container that is attached to the main launch vehicle when it goes into space. This holder acts like a giant candy tin called a Nanosatellite Launch Adaptor System (NLAS.) When it opens, one can imagine these small CubeSats being released like sweets from a tube. They float out over the stratosphere or where ever else the project owner might wish them to go.

CubeSats have been used to patrol around space stations or satellites. They search for malfunctions or other damage. They can gently breeze the length of solar panels and check all is well, even report minor irregularities that can be tackled promptly, in case a fault becomes more substantial.

Now NASA has a programme called CubeSat Launch Initiative (CSLI.) This innovative idea allows free-thinking projects within CubeSats. These projects are independent but hitch a ride, into space, upon a NASA rocket launch. A room for passengers appeals where space exploration is concerned.

Once in space, the NLAS releases its CubeSat passengers out and into orbit. Off they go on their own little adventures, leaving the NASA magic bus to do its own thing, while the little CubeSat goes about its self-indulgent quest for knowledge, in a field of its owner’s choosing. It might take photographs of Earth to study weather conditions, scan space for asteroids, survey the moon, Mars, Venus, or watch material test samples in a space vacuum. There are all sorts of things. These little undertakings can be controlled from a university classroom by students on Earth.

For a university to win the prized chance of controlling a CubeSat, they have to pass stringent tests via NASA monitors who judge each project for viability. The agency gets to filter the financially lucrative bidders for the choice of those most useful on the knowledge acquisition front. This is because NASA will have access to all information gathered before the reports go down to the students in control of the CubeSat project.

There are many CubeSats in orbit already and a growing number of projects waiting in line. NASA will be paid for getting this free information as a transport provider for independent CubeSats, which are just paying passengers on the main launch project.

Everyone wins when this experimental information starts to come in. The CubeSat can cost between $65,000 and $80,000. If there is a launch that can carry four or five CubeSats, NASA gets a little of the cost back towards the main mission and a potential amount of updated and free information. It also ensures that they have a growing and enthusiastic candidates for future space exploration technology.

These delightful little parasitical spacecraft will develop over the decades and all launches might be able to lower funding costs by accommodating CubeSat projects. NASA may find ways to lower costs of building launch projects too, especially developing re-usable craft like the Orion MPCV. Every time an Orion launch goes up it will have CubeSat minor projects paying for a lift. Depending on how many CubeSat projects at $65,000 + it can get aboard; could re-launchable MPCV claw back substantial finances against original costs of building main launch projects in the future.

Imagine the return in the shape of these four-inch cubes. Not to forget long term and constant free information updates. NASA has stumbled upon a large number of independent projects lining up to be selected and waiting to hand over their money to get a CubeSat into space.
How long before large multi-corporate organisations offer large sums of money for their own space exploration tests, lowering the cost on the US taxpayer? Space exploration will cast away all national industry commitment and begin to pay for itself. Privatisation, once again, paves the way.

Eighth Grade Students Doe CubeSats for Space Exploration




Today, eighth grade students are making their own CubeSats - miniature satellites that can go to space on board any rocket and be released into orbit, allowing students to run their own programmes from computers in their classroom. There are so many of these tiny satellites now and they are growing by the day. 

China tested a missile to see if she had the technology to destroy a satellite. This test was successful and prompted other nations to look at ideas to overcome this. CubeSats was the answer - hundreds and soon thousands of them, scattered in orbit.

It seems young wizz kids all over the world are getting into CubeSats and these sorts of technologies are bringing nations together all over the world.

CubeSat Launch Initiative projects - Wonderful nano satellite parasites



CubeSats are a class of research spacecraft that are a sort of nano-satellite. The cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh about 3 pounds. They sometimes clip two or three together to contain more monitoring and comlinks. A U-1 CubeSat is just one 3 pounds four-inch square satellite, while a U-2 or U-3 is the number of CubeSats clipped together. It is housed in a big square container at the outer side of the main launch vehicle once in space. This container acts like a sort of pea pod called a Nanosatellite Launch Adaptor System (NLAS.) When it opens, these small CubeSats are released like peas floating out over the stratosphere or where ever else the project owner’s might wish to take them. CubeSats have been used to patrol around space stations or satellites to search for malfunctions or other damage. They can gently breeze the length of solar panels and check that all is well, even report minor cracks that can be tackled more immediately in case a blemish develops and becomes more substantial.

NASA’s CubeSat Launch Initiative(CSLI) provides opportunities for small satellite payloads (CubeSats) to fly on rockets planned for upcoming launches. These CubeSats are flown as auxiliary and minor ventures upon previously planned and ulterior missions. They are a collection of small independent auxiliary projects that may leave the host launch and go off in search of knowledge in a number of fields. They might photograph Earth and study weather conditions, search independently for asteroids, look at the moon, Mars, Venus. Watch test samples in a space vacuum. There are all sorts of things. For a school or university to win the chance of controlling a CubeSat, they have to pass stringent tests via NASA monitors - people that judge how each project is viable, and also of use to NASA. For they will have access to all information gathered by each CubeSat before the information goes down to the school or university that wins the project.

There are already many CubeSats in orbit and a growing number of projects already in motion. NASA gets useful free information by allowing these independent CubeSats, which are really just parasite travellers on the main launch project. In return, many good things in small packages come NASA’s way. Everyone wins when this experimental information starts to come in. They can cost between $65,000 and $80,000 a CubeSat. If there is a launch that can carry four or five CubeSats, NASA gets a little of the cost back towards the main mission and a potential amount of updated and free information. It also ensures that they have growing and enthusiastic candidates for future space exploration technology.


These wonderful little parasitical spacecraft will develop over the decades and all launches might be able to lower funding costs by accommodating CubeSat projects. NASA may find ways to lower costs of building launch projects too, especially with developing re-usable craft like the Orion MPCV. Every time an Orion launch goes up it will have the main project, but depending on how many CubeSat projects at odd $65,000 + it can get aboard; I wonder if re-launchable MPCV could claw back substantial finances against original costs of building main launch projects. Imagine the return in the shape of four-inch cubes. Also not to forget long-term return and free information updates. NASA may have stumbled upon large numbers of independent projects lining up to be selected and waiting to hand over the money to get a CubeSat into space.
