“NASA will work with our long-term partner, DARPA, to develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027. With the help of this new technology, astronauts could journey to and from deep space faster than ever – a major capability to prepare for crewed missions to Mars,” said NASA Administrator Bill Nelson. “Congratulations to both NASA and DARPA on this exciting investment, as we ignite the future, together.”

Using a nuclear thermal rocket allows for faster transit time, reducing risk for astronauts. Reducing transit time is a key component for human missions to Mars, as longer trips require more supplies and more robust systems. Maturing faster, more efficient transportation technology will help NASA meet its Moon to Mars Objectives.
Other benefits to space travel include increased science payload capacity and higher power for instrumentation and communication. In a nuclear thermal rocket engine, a fission reactor is used to generate extremely high temperatures. The engine transfers the heat produced by the reactor to a liquid propellant, which is expanded and exhausted through a nozzle to propel the spacecraft. Nuclear thermal rockets can be three or more times more efficient than conventional chemical propulsion.
“NASA has a long history of collaborating with DARPA on projects that enable our respective missions, such as in-space servicing,” said NASA Deputy Administrator Pam Melroy. “Expanding our partnership to nuclear propulsion will help drive forward NASA’s goal to send humans to Mars.”
Under the agreement, NASA’s Space Technology Mission Directorate (STMD) will lead technical development of the nuclear thermal engine to be integrated with DARPA’s experimental spacecraft. DARPA is acting as the contracting authority for the development of the entire stage and the engine, which includes the reactor. DARPA will lead the overall program including rocket systems integration and procurement, approvals, scheduling, and security, cover safety and liability, and ensure overall assembly and integration of the engine with the spacecraft. Over the course of the development, NASA and DARPA will collaborate on assembly of the engine before the in-space demonstration as early as 2027.
“DARPA and NASA have a long history of fruitful collaboration in advancing technologies for our respective goals, from the
The last nuclear thermal rocket engine tests conducted by the United States occurred more than 50 years ago under NASA’s Nuclear Engine for Rocket Vehicle Application and Rover projects.
“With this collaboration, we will leverage our expertise gained from many previous space nuclear power and propulsion projects,” said Jim Reuter, associate administrator for STMD. “Recent aerospace materials and engineering advancements are enabling a new era for space nuclear technology, and this flight demonstration will be a major achievement toward establishing a space transportation capability for an Earth-Moon economy.”
NASA, the Department of Energy (DOE), and industry are also developing advanced space nuclear technologies for multiple initiatives to harness power for space exploration. Through NASA’s Fission Surface Power project, DOE awarded three commercial design efforts to develop nuclear power plant concepts that could be used on the surface of the Moon and, later, Mars.
NASA and DOE are working another commercial design effort to advance higher temperature fission fuels and reactor designs as part of a nuclear thermal propulsion engine. These design efforts are still under development to support a longer-range goal for increased engine performance and will not be used for the DRACO engine.
NASA captures photo of ‘bear’s face’ on the surface of Mars
A strange formation that resembles a bear’s face was captured on the surface of the Red Planet by NASA’s Mars Reconnaissance Orbiter last month.
Two perfectly placed craters make up the eyes, a hill with a “V-shaped collapse structure” makes up the nose, and a circular fracture pattern forms the head, according to the University of Arizona’s Lunar and Planetary Laboratory, which controls the orbiter’s camera.
“The circular fracture pattern might be due to the settling of a deposit over a buried impact crater,” the lab explained. “Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?”

The Mars Reconnaissance Orbiter, which lifted off from Earth in 2005, is just one of multiple spacecrafts NASA is using to explore the Red Planet.
NASA MARS ROVER DISCOVERS WEIRD STRING-LIKE OBJECT THAT GOES VIRAL
Last year, the Curiosity rover snapped a photo of what appears to be a door carved into the otherworldly landscape. The internet went wild with speculation, but the Curiosity team later clarified that it’s just “a natural geologic feature.”

NASA retired the InSight Mars lander after four years on the planet last month after it ran out of power.
Perseverance, NASA’s other rover on the Red Planet, has been collecting rock samples with its robotic arm and exploring Mars’ landscape since 2021.
NASA’s Perseverance Rover Completes Mars Sample Depot – Captures Amazing Variety of Martian Geology

Ten sample tubes, capturing an amazing variety of Martian geology, have been deposited on
Throughout its science campaigns, the rover has been taking a pair of samples from rocks the mission team deems scientifically significant. One sample from each pair taken so far now sits in the carefully arranged depot in the “Three Forks” region of Jezero Crater. The depot samples will serve as a backup set while the other half remain inside Perseverance, which would be the primary means to convey samples to a Sample Retrieval Lander as part of the campaign.
NASA Sample Retrieval Lander: This illustration shows a concept for a proposed NASA Sample Retrieval Lander that would carry a small rocket (about 10 feet, or 3 meters, tall) called the Mars Ascent Vehicle to the Martian surface. After being loaded with sealed tubes containing samples of Martian rocks and soil collected by NASA’s Perseverance rover, the rocket would launch into Mars orbit. The samples would then be ferried to Earth for detailed analysis. Credit: NASA/JPL-Caltech
Mission scientists believe the igneous and sedimentary rock cores provide an excellent cross-section of the geologic processes that took place in Jezero shortly after the crater’s formation almost 4 billion years ago. The rover also deposited an atmospheric sample and what’s called a “witness” tube, which is used to determine if samples being collected might be contaminated with materials that traveled with the rover from Earth.
The titanium tubes were deposited on the surface in an intricate zigzag pattern, with each sample about 15 to 50 feet (5 to 15 meters) apart from one another to ensure they could be safely recovered. Adding time to the depot-creation process, the team needed to precisely map the location of each 7-inch-long (18.6-centimeter-long) tube and glove (adapter) combination so that the samples could be found even if covered with dust. The depot is on flat ground near the base of the raised, fan-shaped ancient river delta that formed long ago when a river flowed into a lake there.
“With the Three Forks depot in our rearview mirror, Perseverance is now headed up the delta,” said Rick Welch, Perseverance’s deputy project manager at

Next Science Campaign
Passing the Rocky Top outcrop represents the end of the rover’s Delta Front Campaign and the beginning of the rover’s Delta Top Campaign because of the geologic transition that takes place at that level.
“We found that from the base of the delta up to the level where Rocky Top is located, the rocks appear to have been deposited in a lake environment,” said Ken Farley, Perseverance project scientist at Caltech. “And those just above Rocky Top appear to have been created in or at the end of a Martian river flowing into the lake. As we ascend the delta into a river setting, we expect to move into rocks that are composed of larger grains – from sand to large boulders. Those materials likely originated in rocks outside of Jezero, eroded and then washed into the crater.”

One of the first stops the rover will make during the new science campaign is at a location the science team calls the “Curvilinear Unit.” Essentially a Martian sandbar, the unit is made of sediment that eons ago was deposited in a bend in one of Jezero’s inflowing river channels. The science team believes the Curvilinear Unit will be an excellent location to hunt for intriguing outcrops of sandstone and perhaps mudstone, and to get a glimpse at the geological processes beyond the walls of Jezero Crater.
More About the Mission
One of the key objectives for Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will analyze the planet’s geology and past climate, lay the foundation for human exploration of the Red Planet, and be the first mission to gather Martian rock and soil samples.
Later NASA missions, in cooperation with ESA, will send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help pave the way for human exploration of the Red Planet.
JPL, which is managed for NASA by Caltech, built and manages operations of the Perseverance rover.
Orbiter captures image of a bear’s face on Mars

As a NASA orbiter turned its camera to the Martian surface, the face of a bear seemed to be looking back.
A camera aboard the Mars Reconnaissance Orbiter, called the High Resolution Imaging Experiment, or HiRISE, captured an image of the unusual geological feature in December.
A circular fracture pattern on the Martian surface shapes the head, while two craters resemble eyes. A V-shaped collapse structure creates the illusion of the nose of a bear.
The circular fracture might be due to the settling of a deposit on top of a buried impact crater that had been filled in with lava or mud. The noselike feature is possibly a volcanic vent or a mud vent.
The University of Arizona, which developed the camera with Ball Aerospace, shared the image on January 25.
The photo is reminiscent of another celestial “face” glimpsed by a NASA space observatory in October 2022, when the sun appeared to smile due to dark spots called coronal holes.
And last March, the Curiosity rover spotted a rock formation that resembled a flower on Mars.
The HiRISE camera has been taking images of Mars since 2006, when the Mars Reconnaissance Orbiter began circling the red planet. The powerful camera was designed to capture detailed images of the Martian surface, including features as small as 3 feet (1 meter).
The orbiter circles Mars every 112 minutes, flying from about 160 miles (255 kilometers) above the south pole to 200 miles (320 kilometers) over the north pole.
The spacecraft and its suite of instruments help NASA scientists study the Martian atmosphere, weather and climate, and how they change over time. The orbiter searches for evidence of water, ice and complex terrain and scouts future landing sites for other missions.
Most recently, the orbiter returned stunning images of what winter looks like on Mars.
‘A Bear On Mars?’ NASA Spots Trippy Phenomenon On Planet’s Surface
Scientists looking at the surface of Mars have spotted what looks like a bear staring back at them.
A camera on NASA’s Mars Reconnaissance Orbiter took a photo of the formation on Dec. 12. It was shared Wednesday by the University of Arizona, which operates the camera.
A hill with a V-shaped collapse structure forms the bear’s nose and a circular fracture pattern creates the head, the university’s Lunar and Planetary Laboratory explained in the blog for its High Resolution Imaging Science Experiment (HiRISE) camera.
“The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?” it said.
This is due to a tendency for the human brain to try and see recognizable shapes in objects or data that are otherwise not familiar to us, known as pareidolia.

Intriguing Meteorite From Mars Reveals ‘Huge Organic Diversity’, Scientists Say : ScienceAlert
In a recent study published in Sciences Advances, an international team of scientists led by the Technical University of Munich examined the Martian meteorite Tissint, which fell near the village of Tissint, Morocco, on 18 July 2011, with pieces of the meteorite found as far as approximately 50 kilometers (30 miles) from the village.
What makes Tissint intriguing is the presence of a “huge organic diversity”, as noted in the study, which could help scientists better understand if life ever existed on Mars, and even the geologic history of Earth, as well.
“Mars and Earth share many aspects of their evolution,” Dr. Philippe Schmitt-Kopplin, who is the director of the research unit Analytical Biochemistry at the Technical University of Munich, and lead author of the study, said in a statement.
“And while life arose and thrived on our home planet, the question of whether it ever existed on Mars is a very hot research topic that requires deeper knowledge of our neighboring planet’s water, organic molecules, and reactive surfaces.”
Organic molecules are molecules comprised of carbon atoms that are bonded to hydrogen atoms, but can also contain oxygen, nitrogen, and other elements, as well. The four primary classes of organic molecules include carbohydrates, proteins, nucleic acids, and lipids.
As seen on Earth, organic molecules are analogous to life, but the study notes that abiotic organic chemistry, non-biological processes, have been observed “in other Martian meteorites.”
“Understanding the processes and sequence of events that shaped this rich organic bounty will reveal new details about Mars’ habitability and potentially about the reactions that could lead to the formation of life,” Dr. Andrew Steele, who is a staff scientist at Carnegie Science, a member of the Mars Sample Return Campaign Science Group for NASA’s Perseverance rover, and a co-author on the study, said in a statement.
Dr. Steele has also conducted extensive research pertaining to organic material found in Martian meteorites, to include Tissint.
For the study, the researchers examined the entirety of Tissint’s organic composition, and identified a “diverse chemistry and abundance in complex molecules “, as noted in the study, while also helping to unlock the past geologic processes within the crust and mantle of the red planet.
The researchers also identified a plethora of organic magnesium compounds never before observed on Mars, which could bring new evidence about the geochemical processes that shaped Mars’ deep interior while possibly making a link between the red planet’s mineral evolution and carbon cycle.
NASA’s upcoming Mars Sample Return mission could provide even greater insights into both the organic and mineral composition of the red planet. Dr. Schmitt-Kopplin recently told Universe Today that such a mission could be just as successful as Japan’s Hayabusa2 asteroid sample return mission since they “were able to show that meteorites reflect nicely the chemistry found in the return mission, we probably will be able to do the same.”
Tissint has a total weight of 7 kilograms (15 pounds), and is currently the fifth meteorite classified as being of Martian origin, with a 2012 study estimating it was ejected from Mars approximately 700,000 years ago from some type of violent event.
Tissint draws some parallels with one of the most famous meteorites of Martian origin found on Earth, ALH 84001, which was the subject of much scrutiny in the late 1990s when it was initially believed to contain microfossils, findings that since been rendered inconclusive.
“ALH 84001 was one of the most studied Mars meteorites because it was found in Antarctica and thus was ‘conserved’ in the ice with low contamination,” Dr. Schmitt-Kopplin recently told Universe Today.
“That time looking at molecules of life in the diverse chemistry of that meteorite and seeing in addition biological-like features in microscopy led to a too rapid conclusion of having found life on Mars.”
What new secrets of Mars will Tissint, future meteorites, and the future samples returned from Mars teach us about the red planet? Only time will tell, and this is why we science!

NASA and DARPA Planning Nuclear Rocket That Could Put Humans on Mars
- NASA aims to test a nuclear-powered rocket within five years, the agency said Tuesday.
- An early concept suggests the rockets could get there within 45 days.
- The space agency aims to put humans on Mars for the first time by the late 2030s.
NASA is investing in plans to test a nuclear-propelled rocket by 2027 that could reach Mars within weeks, the agency’s chief Bill Nelson said in a statement this week.
The agency is teaming up with the Pentagon’s Defense Advanced Research Projects Agency (DARPA) to make a rocket that could reach Mars in record time. They aim to test that rocket by 2027.
“With the help of this new technology, astronauts could journey to and from deep space faster than ever – a major capability to prepare for crewed missions to Mars,” NASA administrator Bill Nelson said Tuesday.
NASA’s recent successful Artemis I mission to the moon was only the first step in its plans to advance human space exploration. The agency aims to put humans on Mars, for the first time, by the late 2030s or early 2040s.
Early missions to the red planet would only last about 30 days, so making sure that travel time is minimized is crucial.
Nuclear thermal propulsion is not a new idea for rockets — the concept was first tested in the 60s.
It relies on using a nuclear reactor to heat a liquid propellant such as hydrogen. That heat converts the liquid to gas. As it expands, the gas is funneled through a nozzle, which generates thrust, propelling the rocket forward.
These rockets would be three or more times more efficient than traditional chemical-based rocket engines, and much faster.
Not only would they be able to carry a heavier workload, but they would also travel quicker than their chemical counterparts, per the press release.
Transit to Mars using a nuclear-powered rocket could take four months, a lot shorter than the usual nine months for older rocket models, Reuters reported.
NASA has also funded an application to develop a concept for a new type of nuclear-thermal propulsion system. If that concept proves to work, it could reduce travel time to Mars to just 45 days, per the concept application.
NASA and DARPA to develop nuclear thermal rocket engine that may put humans on Mars: reports
NASA is partnering with the Defense Advanced Research Projects Agency, or DARPA, to use a nuclear thermal rocket engine in space, according to reports.
In a press release on Tuesday, NASA said the nuclear thermal rocket engine could one day be used for NASA crewed missions to Mars.

Both agencies will collaborate on the Demonstration Rocket for Agile Cislunar Operations, or DRACO, program, under a “non-reimbursable agreement.”
NASA’S ARTEMIS I LAUNCH TO BRING US STEP CLOSER TO ‘SUSTAINABLE HUMAN FOOTPRINT ON THE MOON’
The agreement, the release read, is designed to benefit both agencies while outlining roles, responsibilities and processes that could accelerate the program’s development.
“NASA will work with our long-term partner, DARPA, to develop and demonstrate advanced nuclear thermal propulsion technology as soon as 2027,” NASA Administrator Bill Nelson said. “With the help of this new technology, astronauts could journey to and from deep space faster than ever – a major capability to prepare for crewed missions to Mars. Congratulations to both NASA and DARPA on this exciting investment, as we ignite the future, together.”
The nuclear thermal rocket would allow transit between the moon and Mars to take less time while also reducing the risk for astronauts.

As part of the agreement, NASA will lead the technical development of the nuclear thermal engine while DARP will function as the contracting authority for the stage and engine, including the reactor.
DARPA will also lead the overall program, including rocket system integration, procurement, approvals, security, scheduling, and more.
The goal is to be able to demonstrate the rocket in space as early as 2027.
“DARPA and NASA have a long history of fruitful collaboration in advancing technologies for our respective goals, from the Saturn V rocket that took humans to the Moon for the first time to robotic servicing and refueling of satellites,” Dr. Stefanie Tompkins, director, DARPA said. “The space domain is critical to modern commerce, scientific discovery, and national security. The ability to accomplish leap-ahead advances in space technology through the DRACO nuclear thermal rocket program will be essential for more efficiently and quickly transporting material to the Moon and eventually, people to Mars.”
