#Spire wants to improve weather forecasting with tiny satellites will need you a raincoat or shorts tomorrow?

Chances are the weather data you use to determine the answer comes from the roughly 20 satellites orbiting Earth that monitor weather systems.

Spire, a San francisco startup that is currently testing a small group of shoebox-sized satellites, will announce Thursday that it will put its soon-to-launch fleet of commercial satellites to work collecting an unprecedented amount of weather data.

Spire will have 20 satellites orbiting Earth by the end of this year, and at least 100 3. 5 years from now if all goes according to plan.

the satellites will eventually provide 100 times more information. e want to take advantage of technology that available,

With more satellites, the experience will be more akin to pulling up Google maps on a mobile device.

Spire satellites will measure the humidity temperature and pressure the three main ingredients of weather forecasting of Earth atmosphere.

The sensors are attached to satellites designed to only last a few years. There are so many that if one fails it doesn take down the entire system,

Spire is among a growing number of startups to be launching large constellations of satellites into space.

#How to cash in on cheap Earth-watching satellites THERE ARE some big plans brewing for small satellites. With hordes of cheap orbiters filling the skies researchers

The satellite's design is an iteration of the diminutive 10-centimetre Cubesats that have been used for scientific research since 2003.

It wants to hire satellites already in orbit to prospect landfill sites for potentially valuable materials.

That's where satellites come in. If the satellite gives us 1000 potential sites from the 25000 in the UK we would then use drone reconnaissance to get a richer picture of say the wood cover

and surface profile Terra Recovery cofounder Greg Fitzgerald said last week at a meeting of the UK government's space business advocacy group in London.

Initially the firm plans to use information collected by European space agency satellites which have a 1-metre resolution.

But it could later switch to satellites like the 28 imaging cubesats that the firm Planet Labs of San francisco already has in orbit.

Planet Labs ultimately wants a fleet of 100 of the tiny satellites enough to refresh its imagery of the entire planet once a day says Arin Jumpasut a Planet Labs imaging engineer.

#Space station poised to launch open-source satellites Want to do your own space experiment? From next week you will be able to run science projects on the world's first open-source satellites.

And it won't break the bank. Ardusat-1 and Ardusat-X were launched to the International space station (ISS) on 3 august aboard a Japanese resupply vehicle

Known as Cubesats each mini satellite packs an array of devices including cameras spectrometers and a Geiger counter into a cube just 10 centimetres to a side.

and the satellites will then be deployed using a robotic-arm technique tested last year. The method can put several small satellites into orbit around Earth eliminating the need for dedicated launch vehicles and making citizen-science missions like Ardusat more affordable.

No one has given people access to satellites in the same way that we're doing with Ardusat says Chris Wake of Nanosatisfi the San francisco company that builds

and operates the satellites. The maiden launch was funded partially by a Kickstarter campaign with backers buying some of the satellites'time slots to run experiments.

If there are enough extra time slots paying customers will also be able to program controls on the satellites

and run experiments for three days for $125 or for a week for $250. The satellites run Arduino an open-source platform popular with hobbyists which will let anyone write code for an app game

or research project that uses the onboard instruments. Projects that will run on the first two Ardusats are yet to be announced

The first two satellites will orbit for three to seven months before burning up as they fall to Earth.

with fleets of satellites delivering broadband to under-served areas of the world THE race is on to build a new kind of internet.

with the ultimate goal of ringing the planet with satellites that will allow anyone, anywhere,

But while this ensures the satellites are always in the same spot above Earth it means there is a large time lag in the service,

as radio waves take a quarter of a second to make the round trip up to a geosynchronous satellite and back.

To speed up the service firms are looking at using satellites closer to Earth. This month, Virgin galactic and chip-maker Qualcomm announced their backing of a venture called Oneweb.

This plans to put 648 satellites in orbit about 1200 kilometres above Earth's surface, where the round trip time for radio waves is just a few thousands of a second, fine for any online application.

building and launching 4000 satellites to a similar altitude. That would more than double the number of satellites in orbit.

The race has attracted more than just newcomers. Iridium Communications based In virginia, has provided satellite telephone services and low-bandwidth internet since the late 1990s.

Its existing network of 66 satellites is set to be replaced by a new one called Iridium NEXT.

the new satellites will be capable of delivering high-speed internet on a par with what Oneweb and Spacex envisage.

And O3b, a sister company to Oneweb, already has 12 satellites at an altitude of 8000 kilometres.

an alternative route to customers via satellites will be invaluable. It's not the only reason."

"Will the space around Earth become crowded with all these satellites vying to route our data?"

"I'm not worried about the physical interaction of the satellites as much as what they're using for the transmission.

"Beaming down Radio transmission is the most common way to communicate between satellites and Earth.

lower powered satellites that can still talk to the ground easily.""Radio has been the de facto,

"Companies like O3b and Spacex are planning to launch internet satellites with masses of hundreds of kilograms,

lightweight satellites that can piggyback on the launches of other vehicles.""That way every rocket that goes up is kicking off Cubesats,

Instead of building large satellites On earth and then fighting gravity to get them in orbit, the components themselves would be launched,

then come together in space to form a light, powerful satellite. A network of such orbiters should be able to provide coverage that is similar to the signals terrestrial cellular towers already pump out."

these satellites perform valuable functions for humans on earth. Since the launch of Telstar in 1962, satellites have relayed terrestrial communications,

and today both cars and smartphones rely on GPS satellites to know exactly where they are.

Japan's proposed space force would monitor Earth's orbitals with radar and telescopes, looking for harmful debris that threatens satellites.

This isn't an inherently apolitical, altruistic task. In 2007, regional rival China blew up one of its own satellites,

proving that it can in fact destroy satellites, and creating harmful debris for other geostationary machines.

In May Japan's Aerospace Exploration Agency signed an agreement with the United states where they promised to give information on space debris to U s. Strategic Command.

#The first satellite powered entirely by ion engines is online Getting a satellite into orbit is only the first step in making it a useful piece of equipment.

but more modern satellites have relied upon a mix of chemical and electric propulsion. Now Boeing has announced the first all-electric ion propulsion satellite is fully operational.

The satellite in question doesn have a snappy name it a communications satellite called ABS-3a 702sp.

It was launched last March aboard a Spacex Falcon 9 rocket. It has just recently been handed over to its owner

meaning it can remain operational much longer than a similar satellite with conventional thrusters. ABS expects the satellite to remain active for about 15 years.

Ion thrusters are also considerably lighter than chemical engines making launches cheaper. The drawback is the very low thrust of an ion engine.

That why past satellites have carried conventional thrusters as well. Upon delivery to orbit, ABS-3a used its ion thrusters to reach a geosynchronous orbit at 3 degrees west longitude.

the satellite was turned over to ABS on August 31st. Now that the design has proven itself viable,

Boeing is forging ahead with a second satellite for ABS using the same XIPS engines.
