NASA is Considering Other Ways of Getting its Mars Samples Home

In 2021, NASA’s Perseverance rover landed in the Jezero Crater on Mars. For the next three years, this astrobiology mission collected soil and rock samples from the crater floor for eventual return to Earth. The analysis of these samples is expected to reveal much about Mars’ past and how it transitioned from being a warmer, wetter place to the frigid and desiccated place we know today. Unfortunately, budget cuts have placed the future of the proposed NASA-ESA Mars Sample Return (MSR) mission in doubt.

As a result, NASA recently announced that it was seeking proposals for more cost-effective and rapid methods of bringing the samples home. This will consist of three studies by NASA and the Johns Hopkins University Applied Physics Laboratory (JHUAPL). In addition, NASA has selected seven commercial partners for firm-fixed-price contracts for up to $1.5 million to conduct their own 90-day studies. Once complete, NASA will consider which proposals to integrate into the MSR mission architecture.

Perseverance Wraps Up Over 1,000 Days on Mars. Still Going Strong

I can remember when Perseverance was launched, travelled out into the Solar System and landed on Mars in February 2021. In all the time since it arrived, having clocked up 1000 days of exploration, it has collected 23 samples from different geological areas within the Jezero Crater. The area was once home to an ancient lake and if there is anywhere on Mars to find evidence of ancient (fossilised) life, it is here.

The Current Mars Sample Return Mission isn’t Going to Work. NASA is Going Back to the Drawing Board

Human spaceflight is not the easiest of enterprises. NASA have let us know that their plans for the Mars Sample Return Mission have changed. The original plan was to work with ESA to collect samples from Perseverance and return them to Earth by 2031. Alas like many things, costs were increasing and timescales were slipping and with the budget challenges, NASA has had to rework their plan. Administrator Bill Nelson has now shared a simpler, less expensive and less risk alternative.

Perseverance Finds its Dream Rock

If there’s a Holy Grail on Mars, it’s probably a specific type of rock: A rock so important that it holds convincing clues to Mars’ ancient habitability.

Perseverance might have just found it.

Search for Life on Mars Could Level-Up with MARSE Mission Concept

A recent study presented at the 55^th Lunar and Planetary Science Conference (LPSC) discusses the Mars Astrobiology, Resource, and Science Explorers (MARSE) mission concept and its Simplified High Impact Energy Landing Device (SHIELD), which offers a broader and cheaper method regarding the search for—past or present—life on the Red Planet, specifically by using four rovers at four different landing sites across Mars’ surface instead of just one-for-one. This concept comes as NASA’s Curiosity and Perseverance rovers continue to tirelessly explore the surface of Mars at Gale Crater and Jezero Crater, respectively.

Perseverance Sees Phobos, Deimos and Mercury Passing in Front of the Sun

NASA's Perseverance Mars rover used its Mastcam-Z camera to capture the silhouette of Phobos, the larger of Mars' pair of moons, as it passed in front of the Sun on Feb. 8, 2024, the 1,056th Martian day, or sol, of the mission. Image Credit: NASA/JPL-Caltech/ASU/MSSS/SSI

NASA’s Perseverance rover is busy exploring the Martian surface and collecting samples for eventual return to Earth. But the rover recently took some time to gaze upward and observe the heavens. Using Mastcam-Z, the rover’s primary science camera, Perseverance captured Phobos, Deimos, and Mercury as they transited in front of the Sun.

Perseverance is Definitely Inside an Ancient Lake on Mars

The search for life on alien worlds has captivated us for hundreds of years. In some respect, the search for life has expanded to the search for water since it is not unreasonable to assume if there is water then there is a good chance there is life too. When NASA selected the landing site for Perseverance, they were looking for such a body of water and settled upon the Jezero Crater. Images from orbiters reveal a crater that looks like it has been filled with water in the past but further investigations were needed to confirm. Now it seems, Perseverance has risen to the challenge.

NASA Lost Contact With its Ingenuity Helicopter Briefly, but it's Back

This view of NASA’s Ingenuity Mars Helicopter was generated using data collected by the Mastcam-Z instrument aboard the agency’s Perseverance Mars rover on Aug. 2, 2023, the 871st Martian day, or sol, of the mission, one day before the rotorcraft’s 54th flight. Credit: NASA/JPL-Caltech/ASU/MSSS

Imagine remotely flying a drone or small aircraft from a great distance and loosing contact with it during flight. You’d likely assume the worst, that your aircraft was probably laying in a crashed heap in some remote location.

That’s what engineers at NASA’s Jet Propulsion Laboratory went through with the beloved Ingenuity helicopter on Mars, millions of miles away. During a recent quick pop-up flight that was supposed to last just 32 seconds, Ingenuity lost communications before it touched back down. The engineers back on Earth had no idea if the little helicopter landed safely or not.

Future Mars Helicopters Could Explore Lava Tubes

The exploration of Mars continues, with many nations sending robotic missions to search for evidence of past life and learn more about the evolution of the planet’s geology and climate. As of the penning of the article, there are ten missions exploring the Red Planet, a combination of orbiters, landers, rovers, and one helicopter (Ingenuity). Looking to the future, NASA and other space agencies are eyeing concepts that will allow them to explore farther into the Red Planet, including previously inaccessible places. In particular, there is considerable interest in exploring the stable lava tubes that run beneath the Martian surface.

These tubes may be a treasure trove of scientific discoveries, containing water ice, organic molecules, and maybe even life! Even crewed mission proposals recommend establishing habitats within these tubes, where astronauts would be sheltered from radiation, dust storms, and the extreme conditions on the surface. In a recent study from the University Politehnica Bucuresti (UPB), a team of engineers described how an autonomous Martian Inspection Drone (MID) inspired by the Inginuity helicopter could locate, enter, and study these lava tubes in detail.

Perseverance Watches a Dust Devil Whirl Past

NASA’s Perseverance rover captured this Martian dust devil moving east to west at a clip of about 12 mph (19 kph) along “Thorofare Ridge” on Aug. 30.

On August 30th, 2023, on the 899th Martian day (sol 899) of its mission, NASA’s Perseverance rover spotted a dust devil while exploring the Jezero Crater. The images taken by one of the rover’s Navigation Cameras (NavCams) were used to make a video (shown below), which is composed of 21 frames taken four seconds apart and sped up 20 times. Similar to small, short-lived whirlwinds on Earth, these vertical columns of wind form when pockets of hot air near the surface rise quickly through cooler air above it. By studying them, scientists hope to learn more about Mars’ atmosphere and improve their weather models.
