PSLV Successfully Launches 31 Satellites in a Single Flight

ISRO’s Polar Satellite Launch Vehicle, in its forty second flight, successfully launched the 710 kg Cartosat-2 Series Remote Sensing Satellite along with 30 co-passenger satellites today (January 12, 2018) from Satish Dhawan Space Centre SHAR, Sriharikota.  This flight is designated as PSLV-C40.

The lift-off of PSLV-C40 occurred at 0929 hrs (9:29 am) IST from the First Launch Pad.  After a flight lasting 16 minutes 37 seconds, the satellites achieved the polar Sun Synchronous Orbit of  503 km inclined at an angle of 97.55 degree to the equator. In the succeeding seven minutes, Cartosat-2 series satellite, INS-1C and 28 customer satellites successfully separated from the PSLV in a predetermined sequence. The fourth stage of PSLV-C40 fired twice for short durations to achieve a polar orbit of 365 km height in which India’s Microsat  successfully separated.

After separation, the two solar arrays of Cartosat-2 series satellite deployed automatically and ISRO's Telemetry, Tracking and Command Network (ISTRAC) at Bengaluru took over the control of the satellite. In the coming days, the satellite will be brought to its final operational configuration following which it will begin to provide remote sensing data using its panchromatic (black and white) and multispectral (colour) cameras.

The 11 kg INS-1C and and the 100 kg class Microsat, the two Indian co-passenger satellites of Cartosat-2, are also being monitored and controlled from ISTRAC, Bengaluru. The 28 international customer satellites belong to  Canada, Finland, France, Republic of Korea, UK and the USA.

So far, PSLV has successfully launched 51 Indian satellites and 237 customer satellites from abroad."

The rapid satellite separations in PSLVs are something to behold. Not to mention the very little time (and space!) interval between separating Cartosat-2F, the enclosure of the secondary payloads and the subsequent satellites... ain't nobody got time for CAMs!

Planetary Resources reports has received telemetry from Arkyd-6.

https://www.planetaryresources.com/2018/01/planetary-resources-launches-latest-spacecraft-in-advance-of-space-resource-exploration-mission/

Redmond, Wash. – January 12, 2018 – Planetary Resources today announced the successful launch of the Arkyd-6, a 6U CubeSat, containing a demonstration of technology designed to detect water resources in space. The team has already begun to receive telemetry from the spacecraft. The data obtained from the Arkyd-6 will be valuable in the development of the Arkyd-301, Planetary Resources’ next spacecraft platform and the beginning of the company’s space resource exploration program.

In the process of engineering the Arkyd-6, the Planetary Resources’ team was able to modify commercial hardware to be used in space, allowing for the possibility of deep-space missions at greatly reduced costs. This process also allows for control at every stage of development and production resulting in a reliable and innovative product.

“The success of the Arykd-6 will validate and inform the design and engineering philosophies we have embraced since the beginning of this innovative project,” said Chris Lewicki, President and CEO, Planetary Resources. “We will continue to employ these methods through the development of the Arkyd-301 and beyond as we progress toward our Space Resource Exploration Mission.”

Out of 17 elements that will be tested during Arkyd-6’s flight, one of the most crucial technologies is the onboard mid-wave infrared (MWIR) imager. The technical team qualified a commercial sensor to collect pixel-level data and integrated custom optics, creating the world’s first commercial MWIR instrument to be used in space. Based on the findings from this initial flight, Planetary Resources will further develop this sensor technology into the most advanced water resource detection hardware available, which will be incorporated into Arkyd-301.

Chris Voorhees, Chief Engineer, Planetary Resources, said, “If all of the experimental systems operate successfully, Planetary Resources intends to use the Arkyd-6 satellite to capture MWIR images of targets on Earth’s surface, including agricultural land, resource exploration regions, and infrastructure for mining and energy. In addition, we will also have the opportunity to perform specific celestial observations from our vantage point in low Earth orbit. Lessons learned from Arkyd-6 will inform the company’s approach as it builds on this technology to enable the scientific and economic evaluation of asteroids during its future Space Resource Exploration Mission.”

Arkyd-6 will be testing additional technologies such as power generation, attitude determination, instrument operation and two-way communication. Although the spacecraft is fully autonomous and able to execute all functions independently, it will continue to communicate with Mission Control through every critical check point.

The primary payload, CARTOSAT 2F (object 43111/18004A) is actively transmitting on S-band, together with several of the other CARTOSAT satellites. It's alive and well, showing active locking to ground stations.

Screen captures of the satellite deploys. I've put them into a zip file. I counted 24 deploys, so some of them might have been off screen.

As far as I can see, the four SpaceBees have been found and identifed, but...

https://science.slashdot.org/story/18/03/09/2232245/fcc-accuses-stealthy-startup-of-launching-rogue-satellites

Quote
Back in January, the FCC pulled permission from Silicon Valley startup Swarm Technologies to launch four satellites into space after what it says was an "apparent unauthorized launch." IEEE Spectrum reports that the unauthorized launch consisted of four experimental satellites that the FCC had decided were too small to be noticed in space -- and hence pose an unacceptable risk of collision -- but which the company may have launched anyway, using a rocket based in India. The federal regulator has since issued a letter to Swarm revoking its authorization for a follow-up mission to launch four new, larger versions of its "SpaceBee" satellites. From the report:
Swarm was founded in 2016 by one engineer who developed a spacecraft concept for Google and another who sold his previous company to Apple. The SpaceBees were built as technology demonstrators for a new space-based Internet of Things communications network. Swarm believes its network could enable satellite communications for orders of magnitude less cost than existing options. It envisages the worldwide tracking of ships and cars, new agricultural technologies, and low cost connectivity for humanitarian efforts anywhere in the world. The four SpaceBees would be the first practical demonstration of Swarm's prototype hardware and cutting-edge algorithms, swapping data with ground stations for up to eight years.
[...]
The FCC told the startup that the agency would assess "the impact of the applicant's apparent unauthorized launch and operation of four satellites... on its qualifications to be a Commission licensee." If Swarm cannot convince the FCC otherwise, the startup could lose permission to build its revolutionary network before the wider world even knows the company exists. An unauthorized launch would also call into question the ability of secondary satellite "ride-share" companies and foreign launch providers to comply with U.S. space regulations.

This message reflects my personal opinion based on open sources of information.

And here’s the original article on these seemingly unauthorised passengers on this flight.

FCC Accuses Stealthy Startup of Launching Rogue Satellites

Quote
Also on board were four small satellites that probably should not have been there. SpaceBee-1, 2, 3, and 4 were briefly described by the Indian space agency ISRO as “two-way satellite communications and data relay” devices from the United States. No operator was specified, and only ISRO publicly noted that they successfully reached orbit the same day.

IEEE Spectrum can reveal that the SpaceBees are almost certainly the first spacecraft from a Silicon Valley startup called Swarm Technologies, currently still in stealth mode. Swarm was founded in 2016 by one engineer who developed a spacecraft concept for Google and another who sold his previous company to Apple. The SpaceBees were built as technology demonstrators for a new space-based Internet of Things communications network.

Launching Rogue Satellites Into Space Was a ‘Mistake’

Sara Spangelo says she isn’t rebellious by nature. So why did she defy federal regulators?
