China is pressing forward to send over 50 spacecraft into space in 2022.
The country plans to launch the Long March-8 Y2 rocket, a two-stage medium-lift rocket between late February and early March this year.
Long March-8 will depart the Wenchang Spacecraft Launch Site in south China’s Hainan Province – the first launch of China’s new configuration of the Long March-8 rocket without boosters.
According to the developer, the rocket will be carrying 22 commercial satellites in the coming mission, the largest number of satellites to be launched in one flight by China.

“Now the Long March-8 Y2 is undergoing sub-system testing. Judged from the progress of our sub-system testing and data interpretation, the current testing results are normal, and the entire rocket is in a controllable condition,” said Wu Yitian, deputy chief designer of the Long March-8 rocket in a China Central Television (CCTV) interview.
Space station completion
China plans to make a record six launches in 2022 to finish building its space station, according to a blue paper released by the China Aerospace Science and Technology Corporation (CASC), the main contractor of China’s space program, on Wednesday.

A center has been established that includes the study of Unidentified Aerial Phenomenon, or UAPs.
The Interdisciplinary Research Center for EXtraterrestrial Studies (IFEX) is anchored at Julius-Maximilians-Universität Würzburg (JMU), one of the largest universities in Germany.
IFEX focuses on extraterrestrial research projects in the context of science and technology and their innovative application on Earth and in space.
“We want to promote the research on UAP in an interdisciplinary framework, carry out our own projects and seek cooperation with relevant institutions and authorities, such as the Max Planck Society, the German Aerospace Centre DLR, the Luftfahrt-Bundesamt LBA, or the Deutscher Wetterdienst,” says IFEX chairman Hakan Kayal, professor of space technology at the University of Würzburg.

Camera system
Kayal has a long-standing interest in UAPs. Recently, he installed a new camera system on the Hubland campus in Würzburg to detect unknown celestial phenomena using artificial intelligence methods.
Overall, the IFEX work area includes exploration of space, objects in our solar system, stars, galaxies, and the universe as a whole, search for signs of life, search for extraterrestrial intelligence (SETI), research on Unidentified Aerial Phenomena (UAP) as well as further interdisciplinary cooperation and dissemination of extraterrestrial studies.
The research on Unidentified Aerial Phenomena involves development and operating systems for detection, evaluation and analysis, including the investigation of outstanding cases.
Since January 25, 2022, research on UAP has been one of the center’s official goals, put in motion after the JMU Senate approved a corresponding extension of the IFEX statute.

Russia is ready to reactivate its moon exploration agenda, a former Soviet Union enterprise that ended decades ago. The last in the row of pioneering USSR lunar missions was Luna 24 – lobbing back to Earth in 1976 roughly six ounces of near-side collectibles.
The country’s Luna-25 is set to kick-start a sequence of lunar outings that also involves Europe as well as China. A larger plan now being scripted is Russian collaboration with China on building an International Lunar Research Station, intended to be operational by 2035.

NASA’s Curiosity Mars rover at Gale Crater is now wrapping up Sol 3382 duties.
Catherine O’Connell-Cooper, a planetary geologist at the University of New Brunswick; Fredericton, New Brunswick, Canada, reports the robot is continuing its trek towards the “Greenheugh pediment.”

“We passed along this area on our detour to The Prow, and our sedimentologists have a long list of imaging wishes, features which caught their eyes on the initial pass through and which we now get the chance to really examine in detail as we skirt along the base of the pediment.
Stitched together from 28 images, this view was captured on April 9, 2020, Sol 2729 after the rover ascended a steep slope, part of a geologic feature called “Greenheugh Pediment.”

New vantage point
From a new vantage point, the rover’s Mastcam and Chemistry and Camera (ChemCam) are imaging the buttes and hills around it, Mastcam focusing on the “Blackcraig” and “Maringma” buttes, and ChemCam taking long distance imagery of the pediment.

Retraced steps
“Our past couple of drives have been in the order of [164 -197 feet] 50-60 meters as we retraced our steps over known terrain, but as we get closer to the pediment and the steep climb up, our drives will slow down,” O’Connell-Cooper adds.
Recently, an all star, all female, rover planning team planned a drive of nearly 80 feet (24 meters) drive, O’Connell-Cooper reports, “shorter than recent drives, but which will take over an hour as we slowly pick our way forward!”

What goes up…comes down. That’s the case for dozens of just-lofted SpaceX Starlink satellites.
SpaceX issued this statement about the situation:
On Thursday, February 3 at 1:13 p.m. EST, Falcon 9 launched 49 Starlink satellites to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. Falcon 9’s second stage deployed the satellites into their intended orbit, with a perigee of approximately 210 kilometers above Earth, and each satellite achieved controlled flight.
SpaceX deploys its satellites into these lower orbits so that in the very rare case any satellite does not pass initial system checkouts it will quickly be deorbited by atmospheric drag. While the low deployment altitude requires more capable satellites at a considerable cost to us, it’s the right thing to do to maintain a sustainable space environment.

Warming atmosphere
Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday. These storms cause the atmosphere to warm and atmospheric density at our low deployment altitudes to increase. In fact, onboard GPS suggests the escalation speed and severity of the storm caused atmospheric drag to increase up to 50 percent higher than during previous launches. The Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag—to effectively “take cover from the storm”—and continued to work closely with the Space Force’s 18th Space Control Squadron and LeoLabs to provide updates on the satellites based on ground radars.
Preliminary analysis show the increased drag at the low altitudes prevented the satellites from leaving safe-mode to begin orbit raising maneuvers, and up to 40 of the satellites will reenter or already have reentered the Earth’s atmosphere. The deorbiting satellites pose zero collision risk with other satellites and by design demise upon atmospheric reentry—meaning no orbital debris is created and no satellite parts hit the ground. This unique situation demonstrates the great lengths the Starlink team has gone to ensure the system is on the leading edge of on-orbit debris mitigation.

NASA’s Curiosity Mars rover at Gale Crater is now performing Sol 3381 duties.
Reports Michelle Minitti, a planetary geologist at Framework in Silver Spring, Maryland: “After our adventures further uphill, Curiosity is backing down hill to get to the start of the path she will take up to the “Greenheugh Pediment.” We are still surrounded by amazing stratigraphy and have the benefit of having been through here before.”

Mars researchers are eager to fill in missing pieces of terrain, and follow up interesting observations.
Curiosity’s Mastcam and Chemistry and Camera (ChemCam) imaging fills both needs.

Maringma butte
“Mastcam will acquire stereo mosaics across the base of “Maringma” butte, and across another butte east of our current location,” Minitti adds. “Both mosaics are aimed at imaging sedimentary structures in these vertical exposures.”
In complementary fashion, ChemCam will cover the eastern butte layering with a 10×1 Remote Micro-Imager (RMI)
mosaic. “Mastcam will also image a stretch of tilted bedrock layers, dubbed “Plomo,” that stretch uphill away from the rover,” Minitti explains.

And Alpha Particle X-Ray Spectrometer (APXS) were also busy at this stop.
Spread the wealth
Typically on a “touch and go” sol, scientists look at a given target with APXS and MAHLI, and then shoot another target with ChemCam to, in effect, Minitti says, “spread the wealth of data we acquire across a workspace.”
In part, because scientists have ChemCam, APXS, and MAHLI data from this area from their first pass, researchers had the opportunity to focus all three instruments on “El Dorado.”

“We hope between APXS, MAHLI, and ChemCam, one instrument strikes gold at this prominent bedrock layer,” Minitti reports.
Down hill
After the robot’s drive down hill, the Dynamic Albedo of Neutrons (DAN) will acquire both active and passive measurements, the Mars Descent Imager (MARDI) will acquire an image of the terrain under the left front wheel, ChemCam will autonomously shoot a target in the rover vicinity, and Mastcam will acquire a sky survey, Minitti explains.

Curiosity’s Rover Environmental Monitoring Station (REMS) and
Radiation Assessment Detector (RAD) will continually monitor the environment as the robot starts to move out of winter in Gale Crater, Minitti concludes.

The research team at Dewesoft analyzed data as to which governments, organizations, and companies own the most satellites in our orbit.
How many satellites are in space?
As noted by the Dewesoft team, there are thousands of satellites in the sky above us at this moment, orbiting Earth.
Satellites have many uses for the government, military, and even civilians. They provide us the ability to have things like Internet access, television, GPS, and much more.
They also have scientific purposes such as Earth and space observation and provide the means for high-level technology development.
SpaceX – in the lead
More than half of the 4,550 satellites orbiting Earth are used for communications purposes, and that number will continue to rise as tech billionaires look to bring high-speed Internet access to every corner of our planet.
Dewesoft analyzed data collected by the UCS Satellite Database, ESRI, and the Space Foundation to create a list of the 50 owners of the most satellites orbiting Earth.

India appears ready to rekindle its Moon exploration program, apparently eyeing this August to loft the country’s Chandrayaan-3 mission.
Jitendra Singh, Minister of State, Science and Technology, has stated that the Indian Space Research Organization (ISRO) is readying its third lunar exploration mission.
“Many related hardware and their special tests are successfully completed, the launch is scheduled for August 2022,” Singh said in a statement to India’s lower house of the Parliament.

The lunar South Pole site that saw the crash landing of Chandraayan-2 is being targeted, according to some reports.
In 2019, India’s Chandrayaan-2’s Vikram lander and its rover plowed into the lunar landscape and were destroyed. In that mission, an orbiter was successfully placed into lunar orbit. Still operating, it will help in communications for the upcoming Chandrayaan-3 landing attempt.

According to the ISRO website: “The Lunar South pole is especially interesting because of the lunar surface area that remains in shadow is much larger than that at the North Pole. There could be a possibility of presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.”
