WASHINGTON — The light-lift Vega rocket is Europe’s vehicle of choice for small satellites, but has mainly launched spacecraft weighing hundreds of kilograms. While that’s smaller than what Arianespace normally launches on an Ariane 5 or Soyuz, it’s not the “small” that people generally think of when they think smallsats.

Last week, Arianespace signed a contract with smallsat rideshare organizer Spaceflight Industries of Seattle to conduct two Vega launches with a new adaptor for cubesats and microsats. The first of those launches is expected no sooner than 2019.

Spaceflight will line up the passengers for the Small Spacecraft Mission System (SSMS), an adapter developed by the European Space Agency to accommodate 10 to 15 smallsats ranging from single-digit-kilogram cubesats to microsats up to 400 kilograms.

I guess the anti satellite missiles and lasers are a real threat now.

The Air Force is desperate to replace larger satellites that are vulnerable to attack, and fast.

US military leaders are bullish about small satellites as tools to spy on adversaries and provide secure communications, but there’s just one problem: There isn’t a good way to get them into space, on demand.

Inspired by NASAs partnerships with rocket makers like SpaceX, the Pentagon is turning to private industry, as half a dozen companies, most backed by venture capitalists, are working to launch small satellites more cheaply than ever to meet the demands of a growing number of small-satellite startups.

CAPE CANAVERAL, Fla. (Reuters) — SpaceX said all systems and weather were “go” for blast-off on Wednesday of its first high-priority science mission for NASA, a planet-hunting space telescope whose launch was delayed for two days by a rocket-guidance glitch.

On Monday, April 16, the Transiting Exoplanet Survey Satellite (TESS) will launch from Cape Canaveral Air Force Station in Florida. NASA’s new exoplanet hunter will train its sights on nearer, brighter stars than its predecessors did. If TESS lives up to scientists’ predictions, it could energize our search for life in the cosmos.

When the Kepler space telescope launched in 2009, scientists didn’t know what fraction of stars hosted planets. The Kepler mission was a statistical exploration looking to see how frequently planets occur around stars, Harvard astronomer David Latham told Space.com. “One of the big surprises from Kepler was to find this whole population of planets with sizes between that of Neptune and Earth — and there aren’t any in our solar system, zero — and they’re everywhere out there,” said Latham, who’s worked on the Kepler project for nearly 20 years.

“Kepler is what made us become aware that planets are as common as telephone poles,” SETI Institute astronomer Seth Shostak told Space.com.” But the stars that Kepler was staring at for four years … they were all somewhere between 500 and 1,500 light-years away.” TESS will survey the local neighborhood for planets like Earth.

Tracking methane in the air is hard because it rises and spreads from the source. Measurements taken on the ground and from planes vary all over the place.

Hamburg says the satellite, called MethaneSAT, is the best thing yet for quantifying and tracking the gas: “It will be able to see where it’s happening [and] how much, across the globe — not just the big sources, but all the sources collectively, and understand the scale of the problem. That’s the kind of data we don’t have anywhere in the world.”

The satellite will be about the size of a beer keg and is due for launch in three years. It’s funded with money raised from wealthy philanthropists.

A trio of satellites studying our planet’s magnetic field have shown details of the steady swell of a magnetic field produced by the ocean’s tides.

Four years of data collected by the European Space Agency’s (ESA) Swarm mission have contributed to the mapping of this ‘other’ magnetic field, one that could help us build better models around global warming.

Physicist Nils Olsen from the Technical University of Denmark presented the surprising results at this year’s European Geosciences Union meeting in Vienna, explaining how his team of researchers managed to detail such a faint signature.

NASA wants to go to Mars. SpaceX wants to go to Mars. Michio Kaku wants humanity to go to Mars so we can avoid extinction. The rest of us just want to see our species actually set foot on Mars. But first, the moon.

Think of the moon as a launchpad for the Red Planet. As LiveScience found out, Boeing’s Crew Space Transportation (CST)-100 Starliner is going to take advantage of our satellite as a blast-off point for the next frontier. Starliner (the name is about as sci-fi as you can get) is what happens when Boeing, which probably makes everyone think airplanes not spaceships, joins forces with NASA to develop a reusable space capsule that will be able to fly up to seven astronauts to the ISS. It will also be the world’s first commercial space vehicle.

Starliner is even autonomous. Meaning crews will spend less time on training and take off sooner. It only needs one astronaut to fly it, or more like assist it in flight, using tablets and touch screens.

Okay, if you’ve got some spare time, check out this amazing website called Stuff in Space. It’s a simulation of every satellite (alive or dead), space station, and large piece of space junk orbiting the Earth right now.

You can zoom in and out, rotate the Earth and its satellites around. Pick any one object and discover more information about it. Or just leave it running and watch all the objects buzz around in real time. Humans have been busy launching a lot of stuff, and it’s only going to increase.

The simulation was made by James Yoder, an incoming Electrical and Computer Engineering freshman at the University of Texas at Austin, and it’s based on data supplied by Space Track, which is a service of the Joint Space Operations Center. They have a bunch of handy data feeds and APIs that you can use track orbital objects, but I’ve never seen anything as creative as this.
