According to Andrew Jones from gbtimes.com the Shaonian Xing CubeSat will fly as secondary payload with Zhangheng-1 in August:

"China will in August launch its first satellite developed by teenagers as part of an outreach project to engage youth in thinking about space, STEAM education, and even satellite development.

The 2-Unit cubesat, referred to as Shaonian Xing (少年星), and roughly translating to 'Junior Sat' or 'Youth Sat' (or more literally 'star'), is a result of China's Teen Satellite Project.
...
Piggybacking on a seismic mission

With a mass of just a few kilos, to get into space Youth Sat will ride as a secondary payload on the Zangheng-1 mission, also known as the China Seismo-Electromagnetic Satellite (CSES), which will launch on a Long March 2D rocket from Jiuquan on August 16."

ESA says that GomX 4A and 4B are flying in September, with Gunter Krebs listing these satellites being launched with Zhangheng 1.

Due to fly flight in September 2017, GomX-4B is supported through the In-Orbit Demonstration element of ESA’s General Support Technology Programme, focused on readying new products for space and the marketplace.

Put off for a month?

This launch will apparently be the return-to-flight for the CZ-2D after the partial launch failure of the first two GaoJing-1 satellites last December.

Has anyone outside of the Chinese launcher community deduced the partial failure mode?  Was it the first stage?

All I know is that the partial failure mode was not related to commonalities CZ-4 family.

ESA’S LATEST TECHNOLOGY CUBESAT CLEARED FOR LAUNCH SITE

23 November 2017

GomX-4B, ESA’s latest and largest technology-testing CubeSat, will be launched from China early next year, together with the near-identical GomX-4A. The pair will test intersatellite communication links and propulsion while orbiting up to 4500 km apart.

The cereal box-sized GomX-4B has been passed as ready to travel along with its twin from manufacturer GomSpace in Denmark in early December to begin launch preparations in China.

“GomX-4B is scheduled to be launched on a Chinese Long March rocket on 1 February, along with GomX-4A, owned by the Danish Ministry of Defence,” says Roger Walker, heading ESA’s Technology CubeSat initiative.

The majority of tests were made at GomSpace and other facilities in Denmark, apart from thermal–vacuum testing – ensuring that the CubeSats can withstand the hard vacuum and temperature extremes of low orbit – which took place at ESA’s technical centre in the Netherlands.

CubeSats are nanosatellites based on standardised 10x10 cm units. GomX-4B is a ‘6-unit’ CubeSat, double the size of its predecessor GomX-3, which was released from the International Space Station in 2015.

Roger adds, “The two CubeSats will test intersatellite link technology, routing data from one satellite to the other, then down to the ground station. Part of the ground testing ensured they could indeed talk to each other and the actual ground station on an end-to-end basis.”

Once released from the rocket, the CubeSats will first orient themselves to align their antennas. Then GomX-4B will gradually fly away from its counterpart, pausing at around 100 km intervals with their intersatellite links activated to see how well they work.


Their separation will be controlled by new cold-gas propulsion on GomX-4B contributed by Sweden’s NanoSpace company, using highly miniaturised thrusters.

They will maintain their links through flat, patch antennas and software-controlled radios at a maximum distance of some 4500 km – a limit being set by the operating concept of a minimum of 10 satellites equally spaced around the same orbital plane to form a future constellation.

“As well as operating together, the two also have separate payloads,” says Roger. “GomX-4B is the first CubeSat to fly our new HyperScout hyperspectral imager, developed by cosine Research in the Netherlands through ESA’s General Support Technology Programme.

“Hyperscout images Earth in 45 different spectral bands, gathering a wealth of environmental data – so much so, in fact, that the camera must perform its own processing to drastically reduce the amount needing to be sent back to the ground.”

GomX-4B also carries a new small startracker for precise attitude determination developed by Innovative Solutions in Space in the Netherlands, an ESA test payload checking components’ susceptibility to space radiation, and a dedicated radio receiver to detect signals from worldwide air traffic.

“Now the testing has been concluded, our main job is to keep the satellites’ batteries topped off, ahead of their transport to China,” concludes Roger. “Once they arrive, they will be checked and the propellant tanks filled.”

The pair is flying as secondary payloads with China’s Seismo-Electromagnetic Satellite, CSES-1, designed to detect precursor signals of earthquakes in Earth’s ionosphere, an electrically active outer layer of the atmosphere.

Not sure if it is simply a time-zone issue, but the article above has now been updated and lists the launch date as 2nd February:

The two ŃuSat satellites from Satellogic on board are named "Ada" (for Ada Lovelace) and "Maryam" (for Maryam Mirzakhani) respectively. Below are photos of the two satellites being tested at Jiuquan.

According to http://www.telam.com.ar/notas/201801/241641-nanosatelites-ada-maryan.html the launch is scheduled on February 2 at 04:30 in Argentina = 07:30 UTC.

Thanks DF31, but could you please attach your image files? That is the preferred method for showing images. Plus, those are webp files that didn't show up in my browser. I've converted them to jpg.
