A look at the U.S. National Reconnaissance Office’s NROL-61 satellite launch and payload mate:



Launch is tomorrow from Cape Canaveral’s Complex 41 launch pad at 13:37 BST (08:37 EDT).

awesome full burn there.

getting excited, less than two months till spaceX mars plan reveal (sep 2th) and going by nasa time line for human flight, we may well see their spacesuits as well.

A look at Rosetta’s two year journey around Comet 67P/Churyumov–Gerasimenko.


The animation begins on 31 July 2014, during Rosetta’s final approach to the comet after its ten-year journey through space. The spacecraft arrived at a distance of 100 km on 6 August whereupon it gradually approached the comet and entered initial mapping orbits that were needed to select a landing site for Philae. These observations also enabled the first comet science of the mission. The manoeuvres in the lead up to, during and after Philae’s deployment on 12 November are seen, before Rosetta settled into longer-term science orbits.

In February and March 2015 the spacecraft made several flybys. One of the closest flybys triggered a ‘safe mode’ event that forced it to retreat temporarily until it was safe to gradually draw closer again. The comet’s increased activity in the lead up to and after perihelion in August 2015 meant that Rosetta remained well beyond 100 km distances for several months.

In June 2015, contact was restored with Philae again – albeit temporary, with no permanent link able to be maintained, despite a series of dedicated trajectories flown by Rosetta for several weeks.

Following perihelion, Rosetta performed a dayside far excursion some 1500 km from the comet, before re-approaching to closer orbits again, enabled by the reduction in the comet’s activity. In March–April 2016 Rosetta went on another far excursion, this time on the night side, followed by a close flyby and orbits dedicated to a range of science observations.

The animation finishes at 9 August 2016, before the details of the end of mission orbits were known.

The trajectory shown in this animation is created from real data, but the comet rotation is not. An arrow indicates the direction to the Sun as the camera viewpoint changes during the animation.

Rosetta's journey will end on September 30th when it does a descent to the surface of the comet.

You guys believe the ******** that is nasa ? do yourselves a favour and learn the truth.

It's 2016. You can literally pay money to go into orbit. You can speak to astronauts on the ISS by radio and observe them passing overhead with the naked eye. You can see satellite orbit parameters, and using those stats, see and track them in space as they pass by.

This level of intentional ignorance is astounding.
