In 2018, NASA mission planners selected the Jezero Crater as the future landing site of the Perseverance rover. This crater was a natural choice, as it was once an ancient lake bed, as evidenced by the delta fan at its western edge. On Earth, these features form in the presence of flowing water that gradually deposits sediment over time. Combined with the fact that the Jezero Crater’s delta feature is rich in clays, this makes the region a prime target to search for biosignatures – evidence of past (and maybe present) life on Mars!

In recent news, NASA announced that the Perseverance rover had reached the top of Jezero Crater’s rim at a location the science team calls “Lookout Hill.” The rover spent the previous three and a half months climbing the rim, covering a distance of 500 vertical meters (1,640 vertical feet) and making science observations along the way. Now that it has crested the rim, Perseverance can begin what the mission team calls its “Northern Rim” campaign. Over the next year, the rover is expected to drive 6.4 km (4 mi) and visit up to four sites of interest where it will obtain geological samples.

NASA has Plans for More Cargo Deliveries to the Moon

Through the Artemis Program, NASA hopes to lay the foundations for a program of “sustained lunar exploration and development.” This will include regular missions to the surface, the creation of infrastructure and habitats, and a long-term human presence. To facilitate this, NASA is teaming up with industry and international partners to develop Human Landing Systems (HLS) that can transport crews to and from the lunar surface and landers that can deliver payloads of equipment, vehicles, and supplies to the lunar surface.

In a recent statement, NASA indicated that it intends to award Blue Origin and SpaceX additional work under their existing contracts to develop landers that will deliver equipment and infrastructure to the lunar surface. NASA also plans to assign demonstration missions to these companies, in addition to design certification reviews, which will validate their concepts. This decision builds on NASA’s earlier request, made in 2023, that the two companies develop cargo versions of their HLS concepts, which are currently in development for the Artemis III, Artemis IV, and Artemis V missions.

Jared Isaacman is Trump’s Choice for NASA Administrator

As a new President of the United States is elected, the NASA administrator role is usually reviewed. With the election of Trump, a new administrator has been chosen, Jared Isaacman. He is a billionaire entrepreneur, an experienced jet pilot and has himself completed to private flights to space. He was also the first to complete a spacewalk during the Polaris Dawn mission. Isaacman replaces the outgoing administrator Bill Nelson, a former space shuttle astronaut and senator.

NASA Wants Students’ Help Designing Missions to Other Moons

One of NASA’s primary missions is to inspire the next generation of scientists and engineers to join the STEM field. It does so by producing inspirational and educational content on various platforms. But sometimes, it takes a more direct approach by rewarding students for their contributions to solving a particular problem NASA is facing. Recently, the organization announced such a challenge – the Power to Explore Challenge, which is open to submission from K-12 students until the end of January.

Before the decade is out, as part of the Artemis Program, NASA plans to send astronauts to the Moon for the first time since the Apollo Era. To realize this goal, they have contracted with commercial space industries to develop all the necessary components. This includes the Space Launch System (SLS) and the Orion spacecraft that will take the Artemis astronauts to the Moon. There’s also the Lunar Gateway and the Artemis Base Camp, the infrastructure that will facilitate regular missions to the Moon after 2028.

In between, NASA has also partnered with companies to develop the Human Landing Systems (HLS) that will transport the Artemis astronauts to the lunar surface and back. This includes the Starship HLS SpaceX is currently developing for NASA, which will rendezvous with the Orion spacecraft in lunar orbit and allow the Artemis III astronauts to land on the Moon (which will take place no sooner than September 2026). In a series of newly-updated images, SpaceX has provided artistic renders of what key moments in this mission will look like.

NASA’s JPL Lays Off Another 325 People

NASA’s Jet Propulsion Lab has announced a second round of layoffs for 2024, this time laying off 325 people – about 5% of its workforce. The announcement was made on Nov. 12 in a memo sent to employees, which notes the layoffs could have been even larger. The last cut was made this past February, when 530 employees were let go. Part of the issues which forced the layoffs comes from the the possible cancelation of the Mars Sample Return mission. With the October 2024 launch of Europa Clipper, JPL doesn’t have a flagship mission in the pipeline right now.

NASA Wants to Move Heavy Cargo on the Moon

While new rockets and human missions to the Moon are in the press, NASA is quietly thinking through the nuts and bolts of a long-term presence on the Moon. They have already released two white papers about the lunar logistics they’ll require in the future and are now requesting proposals from companies to supply some serious cargo transportation. But this isn’t just for space transport; NASA is also looking for ground transportation on the Moon that can move cargo weighing as much as 2,000 to 6,000 kg (4,400 to 13,000 pounds.)

New Simulation Will Help Future Missions Collect Moon Dust

In this decade and the next, multiple space agencies will send crewed missions to the Moon for the first time since the Apollo Era. These missions will culminate in the creation of permanent lunar infrastructure, including habitats, using local resources – aka. In-situ resource utilization (ISRU). This will include lunar regolith, which robots equipped with additive manufacturing (3D printing) will use to fashion building materials. These operations will leverage advances in teleoperation, where controllers on Earth will remotely operate robots on the lunar surface.

According to new research by scientists at the University of Bristol, the technology is one step closer to realization. Through a virtual simulation, the team completed a sample collection task and sent commands to a robot that mimicked the simulation’s actions in real life. Meanwhile, the team monitored the simulation without requiring live camera streams, which are subject to a communications lag on the Moon. This project effectively demonstrates that the team’s method is well-suited for teleoperations on the lunar surface.

Space Force’s X-37B will Perform “Never Before-Seen Maneuvers” in Orbit

The X-37B Orbital Test Vehicle (OTV) has been shrouded in mystery since its maiden flight in 2011. Designed by Boeing and operated by the U.S. Space Force (USSF), this remotely operated, reusable space plane is designed to operate in Low-Earth Orbit (LEO), 240 to 800 km (150 to 500 mi) above the Earth, and test reusable vehicle technologies that support long-term space objectives. On December 29th, 2023, the X-37B began its seventh mission (OTV-7) and has reportedly been conducting experiments on the effects of space radiation and testing Space Domain Awareness (SDA) technologies.

As part of this mission, the X-37B will soon begin executing a series of novel maneuvers to change its orbit around Earth. These maneuvers will consist of the spacecraft brushing against Earth’s upper atmosphere to shed speed and lower its orbit without expending much fuel—a technique known as “aerobraking.” This is the first time the X-37B has performed such a maneuver, which will help it evade detection by potentially hostile nations and perform undetected low passes over Earth during future missions.
