Now safely in the core module, their first tasks involved setting up the crew-related environment, including the condition of drinking water, oxygen production, sleep, sanitation and other statuses, said Wang Saijin, deputy chief designer of the China manned space program’s astronaut system at Beijing Aerospace Flight Control Center, in a China Central Television (CCTV) interview.
“These are all very important status settings. They also have to organize and move supplies, including arranging those from the Tianzhou-3 and Tianzhou-4 cargo spaceships,” Wang said.
Six-month stay

“We have greatly shortened the time for astronauts to reach the space station since the launch of Shenzhou-12, achieving one-day journey that started at dawn and arrived at dusk. The astronauts had breakfast at Wentian Pavilion in the morning and soon can go to sleep at the space station at night. The space station complex is in great condition for the manned mission,” Gao Xu, deputy chief designer of the China manned space program’s astronaut system under the China Academy of Space Technology told CCTV.
Emergency rescue
Even before the launch of China’s Shenzhou-14 piloted spaceship, the Shenzhou-15 spaceship has been well-prepared for emergency rescue and the rotation mission, according to spacecraft designers.
The trio will complete the assembly and construction of Tiangong, developing it from a single-module structure into a national space laboratory with three modules — the core module Tianhe and two lab modules — Wentian and Mengtian.

The Shenzhou-14 spaceship was launched from the Jiuquan Satellite Launch Center in northwest China’s Gobi Desert on Sunday and successfully docked with the in-orbit space station core module Tianhe, forming a complex with the core module and the cargo craft Tianzhou-3 and Tianzhou-4.
Continuous technological improvements have made the Long March-2F carrier rocket, China’s only rocket to carry out crewed missions, more reliable and safer, Liu Feng, the launch vehicle’s deputy chief designer said before the launch of the crewed spaceship Shenzhou-14.
International taikonauts
Speaking of the future plan for China’s space station, Huang Weifen, chief designer of taikonaut training system of the China Manned Space Program, said China has been cooperating with other countries and she believes there will be more international taikonauts taking part in joint missions with Chinese taikonauts.

“Since 2012, in fact, we’ve been cooperating with the European Astronaut Center in selecting and training, medical monitoring and support and space foods. We also sent taikonauts to each other for training. Such exchanges aim for the taikonauts from the European Space Agency to come to the China Space Station. So, we’ve been making relevant technical preparations and discussing how we should select and train,” Huang told CCTV. “We are actively doing this. And many other countries, for example Pakistan, expressed willingness to join flight missions on the China Space Station. I believe there will certainly be a time for international taikonauts to come.”

Three modules
The trio will cooperate with the ground team to complete the assembly and construction of the Tiangong space station – from a single-module structure into a national space laboratory with three modules: the core module Tianhe and modules Wentian and Mengtian.
The Wentian lab module is set to be launched in July and Mengtian in October.
During their stay in orbit, the Shenzhou-14 crew will also witness the docking of the Tianzhou-5 cargo craft and Shenzhou-15 crewed spaceship with the core module. The two individual crews will live and work together for multiple days, with the Shenzhou-14 trio returning to Earth in December.
China’s Tiangong space station is designed to be a versatile space lab, capable of accommodating 25 experiment cabinets for scientific exploration.
Interdisciplinary research
“Each cabinet is a small-sized lab in space, capable of supporting single subject or interdisciplinary research in space science experiments,” said Lin Xiqiang, deputy director of the agency, at a press conference.

During the construction phase of the space station, nearly 100 experimental research projects have been planned, Lin said.
Multi-level biological experiments on molecules, cells, tissues and organs will be carried out in Wentian by using diverse online detection methods, such as by visible light, fluorescence or microscopic imaging.
Wentian can also provide a variable gravity simulation environment to support the comparative study of the biological growth mechanism in different gravity conditions.

The Shenzhou-14 mission will complete the construction of the Tiangong space station, with a basic three-module structure consisting of the core module Tianhe and the lab modules Wentian and Mengtian.
National space laboratories
The two lab modules are scheduled to be launched in July and October, respectively, and will host many large-scale and multidisciplinary scientific research experiments for astronauts in orbit following the completion of the space station construction, according to the China Manned Space Agency (CMSA).

“As national space laboratories, the modules on China’s space station will be equipped with 25 experiment cabinets, with each cabinet serving as a small-scale space lab for single-disciplinary or interdisciplinary scientific experiments. Overall, they have reached international advanced levels,” said Lin Xiqiang, deputy director of the CMSA.
“The Wentian lab module will be mainly used for space life science research as it is be equipped with experiment cabinets for research on life ecology, biotechnology and variable gravity science. It can support research on the growth, development, heredity and senescence of plants, animals and microorganisms under space conditions, as well as experimental research on an enclosed ecosystem. Through visible light, fluorescent light, microscopic imaging and other online monitoring means, it can support multi-level biological experimental research like on the levels of molecule, cell, tissue and organ. It can also provide variable gravity simulation with a range from 0.01 g to 2 g to support comparative research on the growth mechanisms of organisms under different gravity conditions,” said Lin.

“The Mengtian lab module will be mainly used for microgravity science research as it is equipped with multidisciplinary experiment cabinets for research on fluid physics, materials science, combustion science, fundamental physics and aerospace technology experiments. It can support cutting-edge experimental research like research on the essential laws of materials such as multiphase flow, phase change heat exchange, basic combustion process, and material solidification mechanism in microgravity, as well as research on ultra-cold atomic physics,” Lin said.

Cold atomic clock system
Mengtian will also carry the world’s first space-based cold atomic clock system consisting of a hydrogen clock, a rubidium clock and an optical clock, which will become humanity’s most accurate timekeeping device.
“In the meantime, built on the cold atomic clock system in the Tiangong-2 lab, we will establish the world’s first space-based cold atomic clock system [in the Mengtian lab module] which will consist of a hydrogen clock, a rubidium clock and an optical clock, forming the most stable and accurate time and frequency system in space to support frontier scientific research on gravitational redshift, measurement of fine-structure constant and others,” Lin said.

The world’s first-ever cold atomic clock that operates in space was developed by Chinese scientists. It was launched with the Tiangong-2 space lab in 2016 and has a margin of error of less than one second in 30 million years.
Shenzhou-14 crew
China’s Shenzhou-14 spaceflight commander is Chen Dong. This is Chen’s second time to work in space. He served as a crew member of Shenzhou-11 in October 2016.
Liu Yang, the first Chinese woman in space, flew aboard Shenzhou-9 in 2012 – a 13-day mission.
The new Chinese astronaut, Cai Xuzhe, was selected as a member of China’s second batch of astronauts in May 2010.
China has so far completed eight piloted space missions, sending 13 astronauts into Earth orbit and it is now prepping for its 9th crewed launch.

Mission overview
“The Shenzhou-14 crew will work with the ground team to complete the rendezvous, docking and transposition of the two lab modules with the core module, enter the Wentian and Mengtian lab modules for the first time and help make the environment suitable for their stay,” Lin said.
“They will also cooperate with the ground team to carry out tests on the two-module space station complex, the three-module space station complex, large and small mechanical arms, and the exit function of the airlock cabin. The crew will, for the first time, use the airlock cabin in the Wentian lab module to carry out extravehicular activities for two to three times, and unlock and install a dozen of scientific experiment cabinets in the Wentian and Mengtian lab modules,” Lin said.
There is a small mechanical arm installed on the Wentian lab module and the larger robotic arm on the Tianhe core module. They can work independently or together.
According to Lin, the two mechanical arms can be connected to form a combination that can transfer a heavier load for a larger area range.
“The small arm can be grasped by the bigger one to form a combination, so that they can cover a wider range in extravehicular activities (EVAs), transfer for a larger area range and reach different positions for detailed operations,” Lin said.

Final preparations are underway for launching the Shenzhou-14 crewed spaceship from the Jiuquan Satellite Launch Center in northwest China’s Gansu Province.
The three-member crew for the six-month in-orbit mission is to be unveiled on Saturday morning.
The Shenzhou-14 mission is expected to blastoff on Sunday, June 5, local time, then dock with China’s in-construction space station.
Critical sprint period
Meanwhile, launch crews are in a “critical sprint period,” according to China Central Television (CCTV).
A comprehensive rehearsal including pre-launch function checks and joint tests for the launch were conducted earlier Friday to ensure that facilities and equipment at the launch site are all in good condition, CCTV reports.
Apart from ignition and liftoff, the rehearsal covered all links of the launch mission.
Good status

According to Qin Tong, a senior designer of the Long March-2F carrier rocket with the China Academy of Launch Vehicle Technology (CALT), the launching system of the Shenzhou-14 mission is in good status for takeoff.
“The results of launch rehearsals and tests on the entire system show that the Long March-2F carrier rocket is fully up to the standard. And all functional indicators can meet the requirements for the launch mission,” Qin told CCTV.
Workflow
“The rehearsals helped us test matching of the interfaces of all systems and correctness of the workflow, as well as completeness of the security work. Now the performance of the spacecraft and the rocket is good, and the work for the astronauts is going on well, which means that conditions allow the rocket to be filled with propellant, a critical step for the launch,” Deng Xiaojun, code-zero commander told CCTV. He is tasked with the countdown to ignition for the launch of the Shenzhou-14 crewed mission.
The combination of the Shenzhou-14 crewed spaceship and a Long March-2F carrier rocket was transferred to the launching area on May 29.

NASA’s Curiosity Mars rover at Gale crater has just made a routine check of its set of aluminum wheels.
Of late, the robot has encountered tough terrain in its quest to scale Mount Sharp (apparently an apt name!).
Each of Curiosity’s six wheels is about 20 inches (50 centimeters) in diameter and 16 inches (40 centimeters) wide, milled out of solid aluminum.

The grousers are 19 zigzag-shaped treads that extend about a quarter inch (three-fourths of a centimeter) outward from the skin of each wheel. The grousers bear much of the rover’s weight and provide most of the traction and ability to traverse over uneven terrain.
Dust devils and wind gusts
Meanwhile, shift over to NASA’s Perseverance rover at Jezero Crater.

A new paper — “The dynamic atmospheric and aeolian environment of Jezero crater, Mars” – has been published in the journal, Science Advances. Lead author is Claire Newman of Aeolis Research.
Perseverance rover’s novel environmental sensors and Jezero crater’s dusty environment are detailed, giving rise to a study of dust devils and wind gusts at the site.
“One such event covered 10 times more area than the largest dust devil, suggesting that dust devils and wind gusts could raise equal amounts of dust under nonstorm conditions,” the paper notes.
Why is Jezero Crater so active compared to most other landing sites?
Wind patterns in Jezero crater exhibit strong daytime winds largely controlled by convection cells superimposed on regional, Isidis basin–scale slope winds, and weaker nighttime winds, suggesting blocking of regional winds by local crater slopes, the paper adds.

It has been decades in the making, bolstered by study after study and numerous name changes.
Now tagged as the “Interstellar Probe,” the concept has matured to enable new discoveries that can be made in no other way, by going places yet to be explored.
For the Interstellar Probe mission especially: “It isn’t about where we are going. It’s about the journey out there. And it is a journey now long overdue.”
That’s the assessment of a research paper newly appearing in the journal, Acta Astronautica. Lead author is Ralph McNutt Jr. of the John Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.

Unified view
Interstellar Probe is a mission that can capture a unified view of our heliosphere and its surroundings from the Earth and out into nearby interstellar space.
“Understanding the dynamics and structure of our heliosphere is fundamental to understanding those of other astrospheres, the ‘heliospheres’ which apparently surround all stellar systems, and how they interact with the galaxy, and how those interactions, in turn, inform the knowledge of habitability in other stellar systems besides our own,” the paper explains.
As now envisioned, Interstellar Probe would utilize today’s technology to take the first explicit step on the path of interstellar exploration, and can pave the way, scientifically, technically, and programmatically for more ambitious future journeys – and more ambitious science goals.

Furthermore, with the new class of super heavy-lift launch vehicles — notably NASA’s Space Launch System (SLS) – the paper suggests that a scientifically compelling Interstellar Probe mission can now become a reality.
Relay race
Interstellar Probe is a decades-long mission to reach several hundreds of astronomical units while providing new unified, measurements of the conditions throughout the heliosphere and through the heliosheath – the outer shell of the bubble of charged particles around our Sun.
This artist’s concept shows NASA’s two Voyager spacecraft exploring a turbulent region of space known as the heliosheath, the outer shell of the bubble of charged particles around our sun. After more than 33 years of travel, the two Voyager spacecraft will soon reach interstellar space, which is the space between stars.

By moving forward on Interstellar Probe, “it will take up the relay race that began with Pioneer 10 and is running with less and less energy with Voyager 1 and Voyager 2,” the paper notes.
Pioneer 10 was the plucky little spacecraft that was the first probe to leave the solar system.

To travel as far and as fast as possible with available technology, the use of the SLS Block 2 cargo version is enabling: carrying the spacecraft as well as a 3rd and 4th stage. Solar system escape speeds of at least twice that of Voyager 1 (i.e., up to 7.2 astronomical units per year) should be doable.
Wide net of possibilities
The research paper – “Interstellar probe – Destination: Universe! – makes the case for how fast can one realistically escape the solar system with a scientifically compelling and credible Interstellar Probe mission.
“Our team put a lot of work into making sure the study was as thorough and detailed as possible, while also casting a ‘wide net’ of possibilities,” said APL’s Ralph McNutt. “We eagerly look forward to what our colleagues with the Solar and Space Physics Decadal Survey have to say,” he told Inside Outer Space.

NASA’s Curiosity Mars rover at Gale Crater is wrapping up Sol 3490 duties.
The rover recently made a steep, albeit short, climb, reports Abigail Fraeman, a planetary geologist at NASA’s Jet Propulsion Laboratory.
Curiosity drivers continue to assess the terrain the robot will cross in an upcoming drive.

A recent drive pushed the robot to crest onto a plateau and it was slated to finish climbing a small but steep slope.
Paved road
“The topography,” Fraeman adds, “actually reminds me a little bit of our ascent onto Vera Rubin ridge several years ago, where we similarly crested a steep slope onto a local flat expanse.”
You can get a sense of the rover’s non-horizontal position by looking at its orientation with respect to the ground in this image using its Left Navigation Camera way back on Sol 1809 (2017-09-07), site number 65.

Curiosity starts the plan parked at an impressive 17˚ pitch (front up) and 17˚ roll (left up) for a total 24˚ tilt, Fraeman points out. “Even though this slope is getting close to the limit of what Curiosity can traverse, we don’t think we’ll have any problems unstowing the arm or driving the rest of the way to the top because of the terrain we’re on – nice smooth bedrock with only a thin sand cover is almost the Martian equivalent of a paved road.”

Vein and bedrock targets
Outside of the drive, Curiosity is on tap to continue documenting the surrounding geology and environment.
A newly scripted plan has the rover collecting Chemistry and Camera (ChemCam) Laser Induced Breakdown Spectroscopy (LIBS) observations of a vein target named “Lago Esmeralda” and bedrock target named “Lago de Rei,” as well as some long distance Remote Micro-Imager (RMI) mosaics of a part of the “Bolivar” mound.
“We’ll also grab some more Mastcam images of Bolivar, as well as several significant outcrops around the rover,” Fraeman reports.

The rover’s Mars Hand Lens Imager (MAHLI) and Alpha Particle X-Ray Spectrometer (APXS) was slated to also participate in the science action, with observations of a Dust Removal Tool’ed bedrock target named “Parepona” and vein target named “Cabadiscana,” and also be use MAHLI to image the Curiosity wheels at the start of the new drive.

Several Mastcam and Navcam observations designed to monitor the environment will round out the plan, Fraeman concludes.
As always, dates of planned rover activities are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.

The Asteroid Institute, a program of the B612 Foundation, announced today it is using a groundbreaking computational technique running on its Asteroid Discovery Analysis and Mapping (ADAM) cloud-based astrodynamics platform to discover and track asteroids.
The upshot: The Minor Planet Center has confirmed and added the first 104 of these newly discovered asteroids to its registry. That opens the door for Asteroid Institute-supported researchers to submit thousands of additional new discoveries.

Massive computation
ADAM is an open-source computational system that runs astrodynamics algorithms using the scalable computational and storage capabilities in Google Compute Engine, Google Cloud Storage, and Google Kubernetes Engine.
THOR (Tracklet-less Heliocentric Orbit Recovery) is a novel algorithm used to discover these new asteroids. It links points of light in different sky images that are consistent with asteroid orbits.
“With THOR running on ADAM, any telescope with an archive can now become an asteroid search telescope,” said Asteroid Institute Executive Director Ed Lu. “We are using the power of massive computation to enable not only more discoveries from existing telescopes, but also to find and track asteroids in historical images of the sky that had gone previously unnoticed because they were never intended for asteroid searches,” he said in a press statement.

Collaborative effort
Danica Remy, President of B612, said this new technological milestone was achieved through a collaborative effort with the University of Washington and Google Cloud.
“Rather than looking to the sky, we’ve developed a way to look at historical data sets to discover asteroids and calculate their orbits,” Remy said in an email. “This key technology we have been building lays the foundation for future commerce, and exploration in space as well as to help protect our home planet from asteroid impacts.”

What is next for ADAM/THOR?
The discoveries announced today were made while searching only a small fraction – less than 0.5% – of the National Science Foundation’s NOIRLab dataset – a dataset that’s produced by ground-based, nighttime optical and infrared astronomy facilities.
Asteroid Institute researchers are already at work searching the rest of the NOIRLab data set for asteroids as well as looking at mining other datasets. “With ADAM/THOR, we expect to discover and contribute orbits for tens of thousands of previously missed objects,” according to an Asteroid Institute factsheet.

Last weekend was a busy time at two of China’s launch sites as the country gears up for two key missions to fully build out its first space station.
A Long March-5B carrier rocket arrived at the Wenchang Spacecraft Launch Site on the southern island of Hainan. In July, the rocket will orbit the first space laboratory of China’s space station – the Wentian module (Quest for the Heavens).
Meanwhile, at the Jiuquan Satellite Launch Center in northwest China’s Gobi Desert, a Long March-2F carrier rocket with the Shenzhou-14 spacecraft was rolled out to the launch tower, ready for its takeoff, reportedly June 5.

NASA’s Curiosity Mars rover at Gale Crater has just begun performing Sol 3489 duties.
Intrepid rover engineers again successfully navigated Curiosity a little higher up Mount Sharp – roughly 16 feet (5 meters) and 131 feet (40 meters) on the ground, away from our previous location, reports Lucy Thompson, Planetary Geologist at University of New Brunswick; Fredericton, New Brunswick, Canada.
“The terrain beneath the rover included striated, dusty bedrock and sand ripples with coarse lag deposits,” Thompson adds.

Dusty bedrock
As a member of the geology/mineralogy planning team and the Alpha Particle X-Ray Spectrometer (APXS) payload uplink lead today, Thompson chose several interesting areas in the workspace for potential arm, contact science.
“The rover engineers assessed these targets before we settled on a representative bedrock area.” The plan calls for two APXS observations on the dusty bedrock, and on a brushed area, with accompanying Mars Hand Lens Imager photos of (“Pitinga”).
“This will help us assess the effect of the ubiquitous dust cover on APXS compositional analyses of the bedrock. The measurement of the brushed bedrock also constitutes part of our systematic monitoring of bedrock composition with APXS every 10 meters of elevation gain, as we climb Mount Sharp,” Thompson points out.

This is important as the rover is in a region identified from orbit as showing a change in mineralogy and, potentially, the environment within Gale crater. The brushed target will be imaged with Mastcam, which will also image the two rock targets being analyzed with the Chemistry and Camera (ChemCam) Laser Induced Breakdown Spectroscopy (LIBS): “Rio Pipi” – dusty bedrock in the ground, and “Barama” – layered bedrock face; as well as some crevices within the sand and rock in the workspace.
Mesmerizing view
“Looking beyond the immediate workspace, the view ahead is mesmerizing with interesting textures and structures both in the near- and far-field,” Thompson reports.

Mastcam and the ChemCam Remote Micro-Imager (RMI) is slated to image the platy, darker, layered ledge in the middle of the image in more detail, but offset to the right (”Dukwari”).
“Mastcam will also image a cliff off to the right of the rover to document textures, structures and layering (“Cantarrana”). Once Curiosity has executed all the targeted science observations, the rover engineers are planning a drive towards the lip, Thompson adds. “That should afford us a better view to plan upcoming drives as we continue climbing Mount Sharp.”

Dust storm
The environmental scientists planned several observations to continue monitoring changes in atmospheric conditions and the current dust storm within Gale crater.
These included: Navcam line of sight images, a large dust devil survey, suprahorizon movies, a dust devil movie, and a zenith movie; and Mastcam basic and full tau observations.
After a hopefully successful drive, the robot will image the terrain beneath the rover wheels with the Mars Descent Imager (MARDI).
The Sample Analysis at Mars (SAM) Instrument Suite instrument is also to be running a fake handoff and a blank solid sample evolved gas experiment.
Standard Rover Environmental Monitoring Station (REMS), Dynamic Albedo of Neutrons (DAN) and Radiation Assessment Detector (RAD) activities round out this plan, Thompson concludes.
