Preparations are quickening in China for the country’s next piloted space mission.
Chinese media outlets have noted the arrival of the Shenzhou-11 spacecraft at the Jiuquan Satellite Launch Center in northwest China on Saturday, just two months before it carries two astronauts into space for a 30-day mission.
According to China’s Manned Space Engineering (CMSE) office, general assembly and testing of the piloted craft will begin at the center ahead of the launch scheduled for mid-October.
Space lab first
Shenzhou-11 will transport personnel and supplies to China’s second orbiting space lab — Tiangong-2 — which is to be launched in mid-September. Tiangong-2 was delivered to the center in early July and the carrier rockets arrived last week.

Still unnamed, the Chinese astronauts selected for the mission are both male and have been undergoing intense training, according to CMSE.
Technological renovations
According to Li Bing, chief engineer, testing and launching station at the Jiuquan Satellite Launch Center:
“This is the first time for us to have two manned spacecraft and two carrier rockets at the launching site at the same time. We have to carry out the maintenance work simultaneously. Up till now our work has been carried out smoothly to ensure the successful accomplishment of the two missions.”
According to Li, up to 22 full-length technological renovations have been done during the past three years “in order to forge a more favorable environment for launching manned spaceships in future.”
More mature system
Zheng Wei, assistant chief designer of spacecraft system, China Aerospace Science and Technology Corporation, points out:
“Shenzhou-11 has inherited all the tried and true features of its predecessors of Shenzhou-8, -9 and -10. It is therefore of confirmed stability, higher reliability and more maturity.”
Zheng adds that if there are fewer people on board the Shenzhou, “we can transport more cargo in the stead for to-go and to-come-back trips with materials for space experimentation.”

NASA’s Curiosity rover is now in Sol 1429 of its operations, recently completing a drive of over 148 feet (45 meters). The robot has wheeled closer to the Murray Buttes, reports Ken Herkenhoff at the USGS Astrogeology Science Center in Flagstaff, Arizona.
The weekend plan calls for Chemistry & Camera (ChemCam) target shooting.
“The primary constraint on planning,” Herkenhoff adds, “ended up being power…we tried to fit more into the plan than the rover’s batteries could support! But we were still able to include a lot of good activities into the plan, starting with a dust devil search, dust opacity measurements, and Mastcam stereo mosaics of the Murray Buttes on Sol 1429.”

ChemCam targets
Curiosity’s ChemCam is to acquire Laser Induced Breakdown Spectrometer (LIBS) data on bedrock targets “Matala,” “Cazombo,” and “Ondjiva” before the rover’s Right Mastcam takes a 7×3 mosaic that includes the ChemCam targets.

Overnight and into the early morning hours of Sol 1430, the script calls for the Sample Analysis at Mars (SAM) Instrument Suite to perform the first part of an experiment on the Mojave drill sample that has been stored in the instrument for several months, Herkenhoff explains. The second part of the SAM experiment is planned for the next night, completing early on Sol 1431.

Drive ahead
A planned drive of the rover is slated for Sol 1431, followed by acquisition of the data needed to plan another drive on Monday.
“So, even though we had to remove some activities during planning, the rover will be very busy this weekend,” Herkenhoff concludes.

Now at the start of Sol 1427, NASA’s Curiosity Mars rover has been busily working at the Marimba drill hole.
A second attempt to drill into Marimba went well, however, the new drill sample was not transferred to Curiosity’s Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) device.
Gentle vibration
The problem was due to a recurrence of the electrical short in the percussion mechanism. Therefore, the sample was not delivered to the Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) as planned, explains Ken Herkenhoff of the USGS Astrogeology Science Center in Flagstaff, Arizona.
“So we tried again on Sol 1425, this time without percussion…using only more gentle vibration,” Herkenhoff adds.

Back on track
The rover’s Mars Hand Lens Imager (MAHLI) and the Alpha Particle X-Ray Spectrometer (APXS) were used to observe the drill hole and cuttings.
Planned activities called for dumping the pre-sieved drill sample. “After we dump the sample, we’ll acquire Mastcam, Navcam and MAHLI images to document the pile,” adds research geologist Lauren Edgar at the USGS Astrogeology Science Center.

“This drill site has been challenging,” Edgar notes, “but we’re back on track and ready to drive away soon!”

Now in Sol 1422 operations on Mars, NASA’s Curiosity rover has carried out drill activities at a target site dubbed “Marimba” – but the result is a bit of a mystery.
Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona reports:
“On Sol 1420 we planned a full drill hole on the target “Marimba” to characterize the composition of the Murray mudstone in this location. However, we came in early this morning to find that the drill hole didn’t penetrate very far into this rock target.”
Drill hole different
Using its Mars Hand Lens Imager, clearly the rover-produced drill hole is different, Edgar says. “We’re trying to evaluate why this drill hole is different, and what prevented the drill from completing as planned. The rover is healthy and all other activities completed successfully, so this might just be a harder rock target than we’ve seen before.”

Rover team members are evaluating the drill activity and options for moving forward.
Chemistry with depth
A decision has been made to take advantage of the shallow drill hole “as a way to assess variations in chemistry with depth,” Edgar adds.
So the plan calls for rover Mastcam multispectral and Chemistry & Camera (ChemCam) passive observations of the drill tailings, as well as a ChemCam LIBS (laser-induced breakdown spectroscopy) observation across the drill hole.
Additionally, on the schedule is ChemCam observation of “Cabinda” to assess an alternative drill site, as well as the target “Epukiro” to investigate an interesting vein.

Dump piles
“We’ll also use Mastcam and ChemCam to assess the post-sieve dump piles from the previous drill target “Oudam,” which we dumped on a nearby rock slab,” Edgar says.
Then Curiosity will use Mastcam and Navcam to monitor the atmosphere and search for dust devils.
Also on tap is acquisition of a 360-degree Mastcam mosaic to provide geologic context for this drill site, Edgar reports.

NASA’s Curiosity rover on Mars is wrapping up duties and soon departing Sol 1421 work on the Red Planet.
Ken Herkenhoff from the USGS Astrogeology Science Center in Flagstaff, Arizona reports that Sol 1419 activities were completed successfully, including cleaning the remaining Oudam sample out of Curiosity’s Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA) device.
The focus of Sol 1420 plans was the drilling into the Marimba bedrock target.

Prior to this activity, the plan calls for the Mars Hand Lens Imager (MAHLI) to image the “noseprint” of the Alpha Particle X-Ray Spectrometer (APXS) contact sensor in the Oudam dump pile and the drill target from various distances, Herkenhoff adds.
After the drilling has completed, the drill bit and the new drill hole was imaged by many of the MSL cameras.

Changes in sand deposits
“And once again, we were able to fit some additional Mastcam observations into the plan,” Herkenhoff explains, such as measurements of dust in the atmosphere, a stereo mosaic extending coverage of the arm workspace, images of targets “Cota 1” and “Cota 2” to serve as a baseline for detecting changes in sand deposits this weekend, and two stereo pairs to improve coverage of one of the Murray Buttes.

China is dispatching two of its Long March II F or CZ-2F carrier rockets to the country’s Jiuquan launch site. They are being readied to support launch of the Tiangong-2 space laboratory and the Shenzhou-11 piloted spacecraft.
According to a report on CCTV-Plus news, this is the first time that two CZ-2F rockets have been transferred to the launch center at the same time.
One of the carrier rockets is set to launch in the third quarter of this year (next month) the Tiangong-2 space laboratory. The other booster is to lift off later with two astronauts to dock with the space laboratory.
Final battle
Tiangong-2 arrived at the Jiuquan launch complex early last month and is going through tests prior to its launch.
The Shenzhou-11 piloted craft will carry out a variety of scientific researches and applications, as well as appraise some key techniques and checking on the possibility of long-term human residence in space.
“Let’s put it this way…it’s the start of the final battle of the mission of Tiangong-2 space laboratory. We are going to complete the en-masse lifting and thorough checking of the rocket, upon its arrival at the launch center,” says Jing Muchun, chief commander of CZ-2F rockets on CCTV-Plus.
“The rockets have to be sent into space without a hitch hidden or otherwise. This is our ultimate goal,” says Jing.
If all goes according to plan, the Tianzhou-1 cargo resupply vessel will be hurled into Earth orbit next year to support Tiangong-2 operations. The supply ship will be sent spaceward atop a Long March 7 rocket from the Wenchang launch center in the first half of 2017.
A short CCTV-Plus video is available here showing launch preparations and graphics depicting the Tiangong-2 mission:

China’s Tiangong-2 space lab is being prepared for launch, a true “Space Lab” that will verify key technologies for building China’s space station, explains its chief designer, Zhu Zongpeng.
Zhu explains in a new interview with China Central Television (CCTV) that the Tiangong-2 is being prepared for liftoff in the third quarter of this year.
The piloted Shenzhou-11 spacecraft – with two persons onboard — is also being readied for launch, later to dock with the Tiangong-2.
Three major missions
The space lab will complete three major missions, according to Zhu, who said the Tiangong-2 can be called “China’s first space lab in terms of its function.”
“The Tiangong-2 can be called the first space laboratory of China, and its missions mainly includes mid-term stay,” Zhu adds.
After the docking of the Shenzhou-11 spacecraft with the Tiangong-2, the astronauts will enter the space lab to work and live in the orbiting facility for 30 days.
The second mission, Zhu says, is to dock with a cargo ship next year to implement on-orbit propellant re-supply.
The third mission is to carry out some experiments for China’s future space station, including technical experiments and some relevant experiments involving repair work.

Key technology
The orbit altitude of the Tiangong-2 will reach 393 kilometers from Earth, the same as that of the future space station.
“The orbit altitude of the Tiangong-2 was designed according to the altitude for operating the space station in the future, and is higher than that of the Tiangong-1, mainly aimed at verifying docking and rendezvous technologies for the space station,” said Zhu.
The on-orbit propellant resupply will also be a key technology for the stable operation of the space station.
“We must collect gas from the fuel tank of the Tiangong-2 into a cylinder, so that a pressure difference will be formed to ensure that the propellant will be supplied from the cargo ship to the space lab,” says Zhu, adding that precise and sealed connection of the re-supply pipelines will also be ensured.

Pre-launch testing
Compared with the Tiangong-1, the Tiangong-2 has more facilities to ensure a comfortable stay for the astronauts, including equipment for receiving television programs from Earth and sending e-mails, according to Zhu.
At least 14 experiments will be carried out in the Tiangong-2.
The Tiangong-2 is now under pre-launch testing at the Jiuquan Satellite Launch Center.
China’s space officials note they want to put a permanent human-staffed space station into service around 2022. The construction of the country’s first orbiting space station will be completed by around 2020.
