NASA’s Curiosity Mars rover is now wrapping up Sol 2334 duties.
Curiosity is back in action at Midland Valley, reports Melissa Rice, a planetary geologist at Western Washington University in Bellingham, Washington.

The robot has returned to science after a two week hiatus because of a technical issue.
Curiosity’s most recent science plan included a drive towards a blocky outcrop called “Midland Valley.” The drive was a success, bringing the rover right on top of a targeted chunk of rock.
Safe mode
“But before we could reach out and touch it, Curiosity went into safe mode,” Rice adds. “While the engineers worked to return Curiosity to nominal operations, the science team stood down from planning, eagerly awaiting our chance to get a closer look at Midland Valley.”

A new plan includes a closer look at the rock.
With Mastcam, Chemistry and Camera (ChemCam), the Mars Hand Lens Imager (MAHLI) and the Alpha Particle X-Ray Spectrometer (APXS) scientists are set to investigate two spots on the outcrop: “Alloa” and “Auchterarder.”
Look ahead

Mastcam will also survey its surroundings with mosaics of wind-blown sand features (“Mormond Hill,” “Motherwell” and “Mount Keen”), as well as look back at a previous workspace (towards the previously-explored targets “Curlew” and “Gannet”).
The rover will then perform a look ahead towards a potential future drive destination (at an area with blocky outcrop called “Milltimber”), and a look up to the sky at the dust in the atmosphere, Rice explains. In addition, ChemCam will use LIBS (the laser) to investigate another rock target called “Crathes.”
“The engineering team is working hard to understand the issue that occurred on sol 2320, and upcoming plans will be dedicated to diagnostic activities,” Rice concludes, “and in the meantime, the new observations from Midland Valley will keep us scientists busy!”

Prime Minister Justin Trudeau has announced Canada’s new partnership in the NASA-led Lunar Gateway by developing and contributing a smart robotic system.
That hardware is Canadarm3, designed to repair and maintain the Gateway.
This smart robotic system includes a next-generation robotic arm, equipment, and specialized tools. Using software and advances in artificial intelligence, this highly-autonomous system will be able to:
- maintain, repair and inspect the Gateway
- capture visiting vehicles
- relocate Gateway modules
- help astronauts during spacewalks
- enable science both in lunar orbit and on the surface of the Moon
Test site
The ability to perform these tasks without human intervention will be vital as the Gateway will not be crewed continuously, and communications delays caused by its lunar orbit will prevent direct real-time control of the robotic system from Earth.

The United States-led Lunar Gateway is an international collaboration in human space exploration. About one-fifth of the size of the International Space Station (ISS), it will orbit the Moon and serve as a science laboratory, test site for new technologies, as well as mission control for operations on the Moon.
The Gateway is expected to be fully functional in the Moon’s orbit around 2026.
Accelerator program
Also announced by the Canadian Space Agency (CSA) on February 28 is a new Lunar Exploration Accelerator Program. This program would help Canadian businesses and academic institutions use and test new technologies in lunar orbit and on the surface of the Moon in the fields of health, artificial intelligence, and robotics.
“The program will spur innovation and new technologies that have applications here on Earth, and will help Canadians get prepared for the jobs of tomorrow in the new global space economy,” according to a CSA statement.
Historic investment
Prime Minister Trudeau explained: “Canada’s historic investment will create good jobs for Canadians, keep our astronaut program running and our aerospace industry strong and growing, while opening up a new realm of possibilities for Canadian research and innovation.”
“With the Lunar Gateway, Canada will play a major role in one of the most ambitious projects ever undertaken,” Trudeau added. “Together, with our partners from around the world, we’ll continue to push the boundaries of human ambition, and inspire generations of kids – and adults – to always aim higher and aspire to something greater.”

Recent impacts on the Red Planet, detected by NASA’s Mars Reconnaissance Orbiter.

NASA’s high-flying Mars Reconnaissance Orbiter (MRO) has imaged a recent impact event in Noachis Terra in the southern mid-latitudes of Mars.
The impact was initially discovered in a 2016 MRO Context Camera image, and was not seen in a 2009 picture. “This implies that the impact may be only two years old, but certainly no more than nine years,” according to a statement from the High Resolution Imaging Science Experiment (HiRISE) Operations Center at the University of Arizona in Tucson.

Multiple impacts
“Rather than a single impact crater, we see multiple impacts like a shotgun blast. This suggests that the impactor broke up in the atmosphere on entry. Although the atmosphere of Mars is thinner than Earth’s, it still has the capacity to break up small impactors, especially ones comprised of weaker materials, like a stony meteoroid versus a iron-nickel one.”

MRO imagery shows 21 distinctive craters ranging in size from 1 to 7 meters in diameter. They are distributed over an area that spans about 1,000 feet (305 meters).
“Most observed recent impacts expose darker-toned materials underlying bright dusty surfaces,” researchers Matthew Bourassa, Shannon Hibbard, Eric Pilles and Livio Tornabene report. “However, this impact does the opposite, showing us lighter-toned materials that lie beneath a darker colored surface.”

Crafted from a newly discovered trove of 65mm footage, and more than 11,000 hours of uncatalogued audio recordings, Apollo 11 takes us straight to the heart of NASA’s most celebrated mission—the one that first put men on the Moon, and forever made Neil Armstrong and Buzz Aldrin into household names.
Immersed in the perspectives of the astronauts, the team in Mission Control, and the millions of spectators on the ground, this vivid experience spotlights those momentous days and hours in 1969 when humankind took a giant leap into the future.
Hayabusa2 image captured near the touchdown site roughly a minute after touchdown. The photograph was taken at roughly 80 feet (25 meters) with the Optical Navigation Camera – Wide angle (ONC-W1) on February 22, 2019 (JST).
The color of the region beneath the spacecraft’s shadow differs from the surroundings and has been discolored by the touchdown. At the moment, the reason for the discoloration is unknown but it may be due to the grit that was blown upwards by the spacecraft thrusters or by the bullet (projectile) shot from Hayabusa2 in the sampling process.

Japan’s Hayabusa2 successfully touched down on asteroid Ryugu on February 22 (JST). It turns out that the gentle cosmic kiss between spacecraft and space rock wasn’t without incident.
Hayabusa2 touchdown region overlapped with the planned touchdown site. The touchdown spot sits at the center of the discolored area. Hayabusa2 researchers explain that an accurate touchdown point will be examined during a more detailed analysis in the future. Also shown is the white target marker, which is shining in the reflected sunlight.

In a posted update from the team: “It was a long week for the team members! Until just before the start of the descent, we examined every aspect of landing plan to remove all doubts and increase our level of confidence. We polished the landing sequence to perfection! The team’s all-out battle was rewarded in the best possible way. We are all looking forward to the report of the results.”
Ingenuity after touchdown
“We had to use a little ingenuity for the motion of Hayabusa2 after touchdown,” the team posting adds.
“The spacecraft rose obliquely after touchdown due to the angle of the ground. This meant that in order to return to the home position, it was necessary to exert a force in a direction difficult to achieve due to the orientation of the spacecraft thrusters.”

Perfect somersault
“We therefore added a twist in the spacecraft attitude by performing a 1/20 turn about the Y-axis and 1/6 turn about the Z-axis before firing the thrusters, and then reversing this twist to return to the original position. This change in attitude allowed the thrusters to fire efficiently,” the posting explains.
“Hayabusa2 achieved a perfect somersault over Ryugu –like a ‘lunar somersault’— and then returned to the home position in a dignified manner. It was an ingenious performance to the end.”
Now the Hayabusa2 project team has turned to evaluating the technical score of the touchdown operation.

Selection process
“We are preparing the first Emirati and Arab astronaut to join scientists at the International Space Station. Our objective is to show the world that we are able to contribute to humanity through quality knowledge and scientific discoveries,” explains His Highness Sheikh Mohammed bin Rashid Al Maktoum.
The process of picking the two UAE astronauts emerged from 4,022 applications that were received with 95 shortlisted for medical assessment. An initial interview stage whittled that number down to 39, with 18 entering the final interview stage. Nine of those people were assessed by Russia’s Roscosmos, leading to the final selection of Sultan al-Neyadi and Hazza al-Mansoori.

Here is another head’s up warning about incoming space hardware – but this saga has a bit of an interplanetary tale to tell.
Peel back space history to the 1970’s, a time of Cold War space race histrionics between the Soviet Union and the United States.
The Soviet Union’s Cosmos 482 was launched on March 31, 1972 and was an attempted Venus probe that subsequently messed up its outward bound, rocket-powered escape to that cloud-veiled world.

Now, some 47 years later, leftovers from Cosmos 482 are en route to an Earth reentry.
