ISRO To Launch Third Cartosat Satellite In Mid-DecemberThere will be a few foreign co-passenger satellites...about 15 to 20 (nano satellites)
Its rather intriguing why another Cartosat-2 series satellite was added later to the plan. Considering that the satellite is named 2ER and not 2F I wonder whether one of the earlier satellites met with an as yet undisclosed failure, or that they felt a need for an additional satellite in the fleet.
"We plan to launch Cartosat-2 series satellite 3 mission, which is a follow-on mission in the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imagery, in mid-December," the official said.
Where does it say that this satellite is Cartosat-2ER? The article saysQuote"We plan to launch Cartosat-2 series satellite 3 mission, which is a follow-on mission in the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imagery, in mid-December," the official said.There were three previous Cartosat-2 Series missions (Cartosat 2C, 2D and 2E), so I'm not sure why this one is called Satellite 3.
Where does it say that this satellite is Cartosat-2ER?

"In the next launch, we have a Cartosat along with 28 international commercial satellites, which we will launch in the second half of December," said S. Rakesh, the Chairman and Managing Director of Antrix Corporation Ltd, the commercial arm of state-run Indian Space Research Organisation (ISRO). There will be 25 nanosatellites and three microsatellites from the US and other countries as co-passengers along the space firm's own satellite of the Cartosat-2 series, he said. The satellites will be launched into the orbit onboard the Polar Satellite Launch Vehicle (PSLV), Rakesh added.

THIRUVANANTHAPURAM: After the recent failure of PSLV-C39 on August 31 this year, Isro centres here including VSSC and LPSC are doubly cautious. They are focused on the next mission of PSLV-C40 to launch 31 satellites including Cartosat -2ER by December end this year.Though PSLV-C40 was planned for launch in November end, it is now decided to launch by December end after a series of tests. "Preparations are on for the next mission of PSLV-C40 by next month end to launch 30 satellites at one go including the Cartosat-2ER satellite. It will be a robust launch," Vikram Sarabhai Space Centre (VSSC) director K Sivan had told TOI.
All precautions will be taken to prevent any anomalies, he said. In the previous PSLV launch, there was no design fault. The heat-shield at the top nozzle of the rocket failed to release the satellite into orbit and it could be due to a fault in pyro-techniques, he said.
Normally the heat shield split into two halves at the conical nozzle opens up to release the satellite into the orbit, it failed to open 20 minutes after lift-off, the scientist explained. The heat shield is designed to absorb excessive heat produced by friction against atmosphere during take-off and to protect the components and fuel tanks of the rocket.
"The reason why it failed could be due to some hitch in the pyrotechnic material of the heat shield or probably failure of the springs to trigger the force against atmosphere to open the shield to eject the satellite out. The exact reasons are being ascertained by the 'Failure Analysis Committee of core scientists and the report will be released soon, said a lead scientist at VSSC.While a VSSC scientist said, the failure analysis report is ready but it will be released only within the Isro centres. Based on its findings and recommendations all precautions will be taken to avert any failure, we are doubly cautious. A series of tests will be conducted before the next mission of PSLV-C40 slated for Dec end, he said.

SAC is now referring to the main payload as CARTOSAT-2F
Indian Space Research Organisation (Isro) will launch its latest remote sensing satellite of the Cartosat-2 series, along with 28 foreign satellites riding piggy-back, only in the first week of January, a top Isro official said.Director of Thiruvananthapuram-based Vikram Sarabhai Space Centre (VSSC), K Sivan clarified that there will be no launch this month and that launch services, which halted after the unsuccessful launch of navigation satellite IRNSS-1H on August 31, will "resume in the first week of the new year".
Rakesh Sasibhushan, CMD of Antrix (Isro's commercial arm), told TOI: "The January launch payload will comprise a combination of one Cartosat, 25 nano satellites and three micro-satellites. Finland is the new customer this time. The rest co-passengers are from existing foreign customers. Most of these small satellites are from the US."
The launch of Cartosat-2 by the PSLV C40 rocket is a follow-on mission of the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imageries. The satellite, which carries panchromatic and multi-spectral cameras, is capable of delivering high-resolution data.
...major milestones were met on Christmas day: The team working on CARTO-2F successfully conducted simultaneous post-dynamic deployment of both arrays, stowed and cleared the spacecraft for further activities"
The Indian Space Research Organisation (ISRO) on Friday said it would launch 31 satellites, including India’s Cartosat-2 series earth observation space craft, in a single mission on January 10.... “The launch is tentatively scheduled for January 10,” a senior ISRO official said.
PSLV C-40 launch postponed until January 12ISRO has made a slight change in the flight schedule of the PSLV C-40, which will carry 31 satellites, including a Cartosat series payload. The C-40 will lift off on January 12 instead of the originally announced January 10. The reason given is that one of the smaller Indian payloads is not ready yet. According to ISRO sources, the rocket will lift off from Sriharikota at 9.28 am.

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.
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.
