Watch a Record 104 Satellites Tumble Into Orbit

An Indian rocket delivered a record-setting 104 satellites into orbit Tuesday night.

A camera on board the Polar Satellite Launch Vehicle captured the spacecraft, most of them tiny CubeSats, as they tumbled into orbit—the most placed into orbit by a single vehicle. A majority of the satellites belong to a U.S.-based company called Planet which hopes to establish a network of tiny satellites to provide near-real-time imaging of Earth.

An Indian cartography satellite and two experimental nanosatellites, weather-monitoring CubeSats and student-built experimental craft were also on board. The 101 CubeSats took flight shortly after the rocket entered orbit in a carefully orchestrated maneuver involving 25 “Quadpacks.” Packed with four tiny probes apiece, the Quadpacks used a spring-assisted delivery system to eject the probes into orbit two at a time.

The 88 satellites from Planet, called Doves, will join 12 others already in orbit to form a string of small imaging probes that completely encircles the globe. Placed in a Sun-synchronous orbit that reaches from pole to pole, their network should allow them to take pictures of Earth multiple times an hour once they are all in place. And, because their orbit takes them over the same place every day, it allows for day-by-day comparisons of specific areas.

The company says that with this launch they are operating the largest fleet of satellites ever assembled. The CubeSats they use are only about a foot long, and are often utilized as a low-cost way of testing preliminary technologies and running experiments. The satellites are small enough that they can often squeeze onto launches as secondary payloads, allowing for cheaper rides into orbit.

    Data glut? Does it have any real value, does it matter?

      It matters!

      Only 50 years ago a successful satellite launch was a big deal, now they are pushed out like cheap TVs.

      Imagine if they were nuclear tipped!

        Serious “nuclear tipped” minimum masses about 340 kg. A nuclear artillery shell is about 25 kg (Davy Crockett Weapon System, M-388 shell). it was primarily a radiation weapon.

    Maybe India is building their own version of a ‘wall’. Except this one will keep humans out of the rest of the universe. Kind of reminds me of that old joke about the “Bozone Layer”. Built by aliens to protect the universe from us.
