Select Chinese satellites are to get a re-boost according to China’s Science and Technology Daily. The vehicle would use a robotic arm to dock with the spacecraft, and then carry the satellite to maintain its original orbit.
Simpler, efficient option
The vehicle is being developed by an academy affiliated to the China Aerospace Science and Industry Corporation, noted today by the state-run Xinhua news agency.
Hu Di, the chief designer of the vehicle, said compared with foreign research that focuses on refueling satellites that have run out of fuel, their option is much simpler and efficient, according to Xinhua.
Candidate satellite
The satellite transport vehicle will reportedly take about two years to complete.
One Chinese satellite is listed to possibly be boosted by the carrier craft.
Last year, China’s communications satellite Zhongxing-9A failed to enter the preset orbit after launch.
Ground controllers were able to nudge that spacecraft to a correct orbit – but that space maneuvering took two weeks and used large gulps of fuel, shortening the satellite’s working life.
Orbit adjustments
Zhongxing-9A communications satellite (Chinasat-9A was launched by a Long March-3B rocket on June 18, 2017, but abnormal performance during the third phase failed to deliver the satellite as planned. After conducting 10 orbit adjustments with its onboard thrusters, Zhongxing-9A reach its preset orbit.
Zhongxing-9A is the first Chinese-made satellite for live radio and television broadcasts.
Hu’s team has listed Zhongxing-9A as a potential satellite on which to apply the new in-orbit satellite transport vehicle technology.

NASA’s Curiosity Mars rover is now performing Sol 2115 duties with a priority to image the rover’s wheels. Acquisition of those images is needed to plan a drive back to the Sol 1999 location, where the robot may start another drilling campaign.

Ken Herkenhoff, a planetary geologist at the USGS in Flagstaff, Arizona, reports that the Mars Hand Lens Imager (MAHLI) photos of the wheels taken on Sol 2114 with the dust cover closed show that there is enough dust on the cover to make it difficult to see the wheels.
So a different approach to wheel imaging was planned for Sol 2115.

Left side looks
To minimize the risk of dust contamination of MAHLI’s optics while the cover is open, MAHLI will image only the wheels on the left side of the rover from above the wheels – keeping MAHLI pointing downward while the dust cover is open.
The wheels on the right side of the rover will be imaged by the left Mastcam rather than MAHLI.
Next drive
“Then the rover will turn in place to allow imaging in the direction of the next drive, toward the southwest,” Herkenhoff adds. “After acquiring the standard post-drive data, Mastcam will observe the Sun and crater rim to continue the monitoring of the dust opacity over Gale Crater.”

These observations will be repeated twice early in the morning on Sol 2116 to look for short-term changes in opacity.
In addition, the robot’s Chemistry and Camera (ChemCam) will use the Autonomous Exploration for Gathering Increased Science (AEGIS) software to autonomously select a bedrock target for a 3×3 Laser Induced Breakdown Spectroscopy (LIBS) raster, Herkenhoff concludes.

Blue Origin’s New Shepard vehicle successfully flew today, a step closer to providing pay-for-ticket human space travel on suborbital treks.
Exhilarating ride
As posted by Blue Origin: “During this mission, known as Mission 9 (M9), the escape motor was fired shortly after booster separation. The Crew Capsule was pushed hard by the escape test and we stressed the rocket to test that astronauts can get away from an anomaly at any time during flight. The mission was a success for both the booster and capsule. Most importantly, astronauts would have had an exhilarating ride and safe landing.”

“This isn’t the first time we’ve done this type of extreme testing on New Shepard. In October of 2012, we simulated a booster failure on the launch pad and had a successful escape. Then in October of 2016, we simulated a booster failure in-flight at Max Q, which is the most physically strenuous point in the flight for the rocket, and had a completely successful escape of the capsule.”
“This test on M9 allowed us to finally characterize escape motor performance in the near-vacuum of space and guarantee that we can safely return our astronauts in any phase of flight.”

NASA’s Curiosity Mars rover is engaged in Sol 2114 duties, finishing up at the Voyageurs drill site.
Reports Mark Salvatore, a planetary geologist at the University of Michigan in Dearborn: “After our attempt to drill the Voyageurs target did not reach sufficient depth due to the impressive hardness of the rock, the team is beginning to finish up its activities at this location before heading a bit further uphill to find a more suitable (i.e., softer) drill target.”
Hardest yet observed
Salvatore notes that all evidence suggests that this rock target is one of the hardest yet observed in Gale crater, a property that may be indicative of this entire section of the Vera Rubin Ridge.
“To a geologist, variations in rock hardness could indicate several different physical and chemical properties about a rock,” Salvatore adds. “It is important for us to further characterize and understand why this rock unit is so much harder than the underlying rocks within the Murray formation.”

Formation mechanisms
Salvatore speculates, could this increased hardness be related to changes in water chemistry as the sedimentary rocks were being deposited? Or, could this increased hardness be due to subsequent cementation as iron-rich water was injected into the previously deposited sedimentary rocks?
“In order to address these possible formation mechanisms (and countless others), we must continue to gather data on the physical, chemical, and mineralogical properties of this portion of the Vera Rubin Ridge,” Salvatore explains.
New plans
A new set of Curiosity activities contain a combination of scientific investigations and engineering activities.
The plan starts with a short imaging science block where Mastcam will be used to acquire images of the surrounding landscape to search for short-term changes to the surface, including sand migration and changes to dust cover.
The robot’s Navcam will also be used to investigate the atmospheric dust content and to search for nearby dust devils.
Following this block of observations, Curiosity will use the Mars Hand Lens Imager (MAHLI) high-resolution camera to investigate the shallow Voyageurs drill hole and to image the rover wheels with its dust cover closed (to avoid dirtying the camera lens).
Drill hole documentation
“After a short nap and a data uplink to the Mars Reconnaissance Orbiter as it passes overhead,” Salvatore says that Curiosity is slated to embark on another block of science activities. This second suite will include Mastcam images of the dusty atmosphere, a Chemistry and Camera (ChemCam) laser-induced breakdown spectroscopy (LIBS) chemical analysis of the Voyageurs drill hole, a LIBS measurements of the ChemCam calibration target, and a follow-up Mastcam documentation image of the drill hole.

This will conclude the sol 2114 science activities.
Deluge of discussions
The team first had to deal with the realization that the drill activities at the Voyageurs target did not penetrate deep enough into the target to acquire materials for analysis onboard the rover.
“While disappointing, the information gathered about the rock properties and drill activities led to a deluge of productive scientific discussions about how to proceed and what these observations tell us about the geologic environment that Curiosity is investigating,” Salvatore reports.
Scientists and engineers can collectively turn a “frustrating sigh into a gasp of excitement” as researchers think about next observations and what more they have to learn about this interesting and foreign environment, Salvatore concludes.

Back in June, NASA held a press meeting to detail new findings from the space agency’s Curiosity Mars rover.
The Mars machinery had found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface.
“Are there signs of life on Mars?” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program, at NASA Headquarters. “We don’t know, but these results tell us we are on the right track.”

Critical review
A critique of that NASA announcement and related scientific papers has been written by former Viking experimenters. After landing in 1976, the two Viking craft carried out dedicated life-detection investigations.
Gilbert V. Levin was the leader of the Viking Labeled Release (LR) Life Detection Experiment and Patricia Ann Straat was a Viking co-experimenter.
Writing a Forum article in the journal Astrobiology, the two scientists note that the June 7, 2018, NASA news conference and two related papers in Science regarding the findings of organic molecules and methane on Mars “are exciting for the possibility of both ancient and current life on Mars.”
NASA’s Curiosity rover used an instrument called SAM (Sample Analysis at Mars) to detect seasonal changes in atmospheric methane in Gale Crater. The methane signal has been observed for nearly three Martian years (nearly six Earth years), peaking each summer.

Indication of current life
That said, Levin and Straat write: “While ostensibly contending they are seeking life, each finding pointing in that direction seems to be immediately contra-indicated by the finders and in all of NASA’s releases and supported scientific publications.”
For instance, the paper on methane in the atmosphere of Mars did provide important new information, they add. That is, monitoring the localized seasonal cycling of atmospheric methane, with substantial and repetitive amplitudes over the three Martian years (six Earth years).
But while acknowledging that almost all methane in Earth’s atmosphere is of biological origin, the authors of that paper propose an abiotic scenario “to explain away this strong indication of current life,” Levin and Straat point out. “On the other hand, this new result makes a possible biological source proposed to explain the cyclical methane on Mars even more tantalizing,” the Viking scientists add.
Strong evidence
NASA has not dispatched another life-detection experiment to Mars since the 1976 Viking mission Labeled Release (LR) experiment, Levin and Straat write, despite that experiment obtaining “strong evidence” for current microbial life on the Red Planet.

“At that time, this evidence was overridden by the presumed lack of liquid water and the failure of the Viking GCMS [Gas Chromatograph Mass Spectrometer] to find any organic matter. Both have now been found,” Levin and Straat point out.
“In the 41 years since Viking, none of the many attempts to explain away the LR results nonbiologically has withstood scientific scrutiny, so no barrier remains to preclude the possibility of extant microbial life on Mars, or that the LR experiment detected it,” Levin and Straat conclude.

Astrobotic’s Peregrine lunar lander is to soft land on the Moon courtesy of propulsion provider, Dynetics of Huntsville, Alabama.
The Pittsburgh, Pennsylvania-based Astrobotic plans to start delivering customer payloads once a year starting in 2020.
In a multi-mission deal announced today, Dynetics will integrate Peregrine’s main engines and attitude control thrusters, controller electronics, tanks, and feed system into a single system that performs all propulsive maneuvers from cruise to soft landing on the Moon.
Astrobotic-Dynetics agreement
According to an Astrobotic press statement, the Dynetics-led system will feature a propellant with a next-generation oxidizer called MON-25, which has a higher nitric oxide content to provide better thermal capability to operate more efficiently in deep space environments than previous oxidizers.

NASA’s Curiosity Mars rover is carrying out Sol 2113 science tasks after being thwarted in performing new drilling in a selected target.
“Hard as a rock,” reports Lauren Edgar, planetary geologist at the USGS in Flagstaff, Arizona. “Unfortunately, we found out this morning that the ‘Voyageurs’ drill target was a much harder rock than expected. While our drill plan executed perfectly, our bit stopped short of the full depth we need for sampling. The engineers are still evaluating the data to better understand the target,” Edgar adds.
Longer-term strategy
The Curiosity science team is coming up with a new plan, and also thinking about a longer-term strategy. “Ultimately, we decided to focus on contact science and documenting the mini drill hole in today’s plan,” Edgar notes.

The new plan involves several Navcam observations to monitor atmospheric opacity during the ongoing dust storm. Also on tap is use of the rover’s Mastcam in change detection observations mode to characterize the movement of sand.
These observations will be followed by several Chemistry and Camera (ChemCam) scans to assess the diversity of color and composition in nearby bedrock.
Additionally, ChemCam Remote Micro-Imager (RMI) imagery of the “Voyageurs” target will be taken to help with targeting the drill hole with ChemCam in a follow-on plan.
Drill hole inspection
A few more environmental monitoring activities are part of the plan, including a Navcam line-of-sight image, Mastcam tau, and crater rim extinction observation, Edgar adds. “Then Curiosity will image the drill chuck, drill bit, and turret, to monitor our tools.”

An evening Alpha Particle X-Ray Spectrometer (APXS) integration on the drill tailings is scheduled, and overnight a longer APXS integration on the drill hole is slated.
Summing up, Edgar concludes: “Today is a reminder that it’s hard to operate a rover and drill on another planet, but I’m hopeful that we’ll find a way to sample this part of the ridge!”

Prime time rocket
A further $7 million will go to Orbex, a UK-based spaceflight company, to build an innovative new rocket dubbed Prime for launch from Sutherland, as well as $3 million to Highlands and Islands Enterprise to develop the spaceport. The spaceport could see rocket lift-offs from the early 2020s.
With its high northern inclination, the UK is a geographically strategic location for launch, and the north of Scotland is well-placed to reach highly sought-after satellite orbits such as polar and near-polar orbit.

The Prime booster would deliver small satellites into Earth’s orbit using a single renewable fuel, bio-propane engine that cuts carbon emissions by 90% compared to hydrocarbon fuels, according to a press statement.
According to Orbex, Prime uses a novel zero-shock staging system called Magic, which leaves zero orbital debris. It also features a novel reusability concept, with an innovative new low mass recovery and reflight system.

One-stop-shop
The UK Space Agency announced at the Farnborough International Airshow a total of $41 million in government grants to establish the UK’s first spaceport in Sutherland.
A number of sites across the UK are developing their spaceport plans. Sites such as Newquay, Glasgow Prestwick and Snowdonia will be boosted by a new $3 million strategic development fund to grow their sub-orbital flight, satellite launch and spaceplane ambitions.
The announcement to develop launch capability is being viewed as Europe’s first one-stop-shop for building, launching and operating satellites.
