fantastic step forward! does anybody know how much they actually sell/sold the launch? I could not find good data. The only phrase in the article that I doubt is this one "Satellite launches are a lucrative business" ...

The Small Satellites Systems and Services Symposium, the "4S Symposium", is a biennial event that was first held in 1992. The 4S Symposium is a good occasion to present results to an international audience and to learn what's happening worldwide in

Good news for space - bad news for dutch residents...

At a meeting of the American Geophysical Union in San Francisco in December, he reported an average figure that was between 0.005 and 0.008 per cent greater than the value for Earth's mass established by the International Astronomical Union. A disc of dark matter around the equator 191 kilometres thick and 70,000 km across can explain this, he says. Harris has yet to account for perturbations to the satellites' orbits due to relativity, and the gravitational pull of the sun and moon. Maybe relativistic GPS could improve this even further? As a side note however, the Juno spacecraft flyby showed an gravity acceleration which matched the calculations, casting doubts on the earlier calculations.

The Wall Street Journal hears that the search firm is preparing to build 180 "small, high capacity" satellites that will go into low orbit and provide internet connections to underserved areas

sorry, did not see your earlier post ... fully altruistic move of course as they claim

actually I posted about it first :P

Nice gif...

At 8:33 a.m., (Japan Standard Time) January 15, 2017, SS-520 No. 4, JAXA's sounding rocket launched from the Uchinoura Space Center. Through SS-520 No. 4 launch, JAXA sought for research and development of launch vehicles and satellites and the launch demonstration of TRICOM-1, its onboard nanosat that weighs about 3 kilograms. The launch was part of Japanese government's program for development of launch vehicles and satellites in public-private partnerships. Long story short: Space-X has the better fireworks

A team of Russians crowdfunding a satellite to annoy astronomers ;) A satellite that will become the brightest star in the night sky

team? only one person, correct?

according to the website they have a whole team of people working on various aspects of the mission.

The ability to teleport photons through 100 kilometres of free space opens the way for satellite-based quantum communications, say researchers

What's next? Lego satellites!

A vast bubble of hot, rarefied gas has been revealed as a source of cosmic rays - the mysterious particles that batter the Earth continuously. The observation of the so-called superbubble, measuring more than 100 light-years across, was made using gamma rays collected by NASA's Fermi satellite and sheds light on the origin of cosmic rays in regions of massive-star formation.

Earth's irregular natural satellites (NES) that are temporarily captured from the near-Earth-object (NEO) population. --> Possibly interesting for NEO exploration? http://arxiv.org/abs/1112.3781

How early could we detect these coming?

Agency wants to send mini robots into space to recycle and reuse antennas from more than 1,300 dormant satellites in geostationary orbit above the earth.

An international team of researchers have developed a new type of gyroscope that is the first to measure the "wobble" in the rotational axis of the Earth from a ground-based laboratory. Astronomers normally track this wobble by continuously monitoring the position of distant objects, such as quasars. But this new method will provide a much simpler and cheaper alternative to these large-scale astronomical readings, the scientists claim.

is this of any use for spacecraft?

mmm it's like saying that you can replace satellite tracking by accelerometers on-board satellites... for Leo: you'd better put an atomic gyro on a spacecraft these laser gyro are huge !

Out-of-control Russian space probe may be 'most toxic falling satellite ever: A Russian space probe aiming to land on a Mars moon was stuck circling the Earth after equipment failure Wednesday, and scientists raced to fire up its engines before the whole thing came crashing down.

Is it just me, or is uncontrolled space junk re-entry becoming trendy?

this was a fantastic mission - ... what a pity!

New technology (STARE-a constellation of nano-satellites) for tracking satellites and space debris could improve the accuracy from 1km (current by NORAD) to less than 100m. Increasing the reliability of collision detection, preventing 99% of false warnings.
