India sets new world record, launching 104 satellites at once.

Creating a new world record in the process, India successfully kicked off their 217 launch calendar February 14 by launching a Polar Satellite Launch Vehicle with 104 satellites. The rocket launched at 10:58pm EST from the Satish Dhawan Space Center.

Lofted into a sun-synchronous orbit by the rocket’s fourth stage, 101 cubesats accompanied three larger satellites on the mission. CartoSat-2D is the fourth in a series of high-resolution Earth-imaging satellites domestically designed by India. Less than ten seconds after CartoSat-2D was deployed, the INA-1A and 1B satellites were released. These two satellites are technology demonstrators for a new, smaller satellite bus that India hopes can attract universities and small businesses for space-based payloads.

Of the 101 cubesats deployed, 88 belonged to the Planet company, which - when combined with 100 identical satellites already in polar orbit- will photograph the entire surface of the Earth every day. Eight other cubesats belonged to Spire Global, and will measure atmospheric conditions and global shipping traffic. The remaining five are scientific and communication technology demonstrators

ISRO - the Indian Space Research organization - released a stunning video of the PSLV launch, the first time footage from onboard rocket cameras have been released. Key events in the rocket’s ascent can be seen, including the jettisoning of its six strap-on solid rocket motors, separation of its second and third stages, and jettisoning of the payload fairing.

On July 5, 2016, the moon passed between NOAA’s DSCOVR satellite and Earth. NASA’s EPIC camera aboard DSCOVR snapped these images over a period of about four hours. In this set, the far side of the moon, which is never seen from Earth, passes by. In the backdrop, Earth rotates, starting with the Australia and Pacific and gradually revealing Asia and Africa.

SpaceX just filed for a constellation of 4,425 satellites to provide Internet from orbit

Space Exploration Holdings, LLC seeks operating authority (i.e., approval for orbital deployment and a station license) for a non−geostationary orbit satellite system in the Fixed−Satellite Service using the Ku and Ka frequency bands. 

The SpaceX non-geostationary orbit (“NGSO”) satellite system (the “SpaceX System”) consists of a constellation of 4,425 satellites (plus in-orbit spares) operating in 83 orbital planes (at altitudes ranging from 1,110 km to 1,325 km), as well as associated ground control facilities, gateway earth stations and end user earth stations.

Earlier this week, NASA released a number of their videos of Earth, other planets, and rockets, in newly shareable form - added through their own pages at giphy and pinterest for people to use.

This clip combines 6 months of observations of Africa and the middle east from space into one short clip.

“From both the kinetic energy table and visualization you can tell visually that mode 5 is a major mode of the trackers and calorimeters. This sort of understanding can be determined rather effectively from the modal effective mass and visualization as you can see here.
