First up, on September 27th at 03:23 UTC, China launched two environmental observation satellites onboard a Long March-4B.
Huanjing-2A and 2B were sent to orbit from Launch Complex 9 in Taiyuan Satellite Launch Center. According to the China Academy of Space Technology (CAST), HJ-2A and HJ-2B will provide 16-meter multispectral and 48-meter hyperspectral and infrared image data.
The mission patch features the Long March-4B in the foreground, with trees, water, and land — typical imagery found other mission patches from satellites with similar missions — and the two satellites shown in the background.
Next up: on Monday, September 28th at 11:20 UTC, a Roscosmos Soyuz-2.1b was launched by Russian Aerospace Forces from Site Number 43 at the Plesetsk Cosmodrome. Onboard were three Gonets M communication satellites and eighteen small satellites in orbit.
Gonets M-27, M-28, and M-29 join the Gonets-D1M constellation, which supports international health organizations to meet their global communications needs for the transfer of medical data and records to remote sites. The Gonets-M satellites share a common design with the military Rodnik communications satellites and are used for store-and-dump operations where data is uploaded to a satellite, stored in its memory, and later downlinked to another user. The name Gonets means “messenger”. They have a planned lifetime of five to seven years and weigh about 280 kilograms or roughly the same as a brown bear.
The smallsats that hitched a ride on the launch belong to a variety of international customers and included three remote sensing smallsats that belong to a Finnish customer and some technology demonstrators for customers in Canada and Germany.
To wrap things up, here’s a running tally of a few spaceflight statistics for the current year:
Toilets currently in space: 4
Toilets burned up: 2
Total satellites humans put into orbit: 915 (includes those launched from other in-orbit craft, such as the ISS)
Total satellites from launches: 887
Total Starlinks: 653
Total 2020 orbital launch attempts: 77 (including 9 failures)
I keep track of orbital launches by where they launched from, also known as spaceport. Here’s that breakdown:
French Guiana: 4
New Zealand: 4
Your random space fact for the week is in memory of our friend Paranor: On May 3rd, 1984, American astronomer Brian Skiff of Lowell’s Anderson Mesa Station, Arizona discovered a dark Alauda asteroid from the outer region of the asteroid belt, approximately 29 kilometers in diameter. Its designation is 3325 TARDIS.
