On the floor of Mars, a rover has stuffed over two dozen hermetic titanium tubes with pristine rock samples, every a bit of thicker than a pencil.
Some tubes have been stashed on the Pink Planet’s floor, whereas others are held contained in the rover’s stomach. NASA and the European House Company are planning to return a few of these valuable rock samples to Earth, the end result of a decades-long dream to retrieve pristine rocks from Mars.
The formidable, multi-billion-dollar effort, nonetheless, has been tormented by issues about ballooning prices.
Now, in a press briefing held Tuesday, NASA officers stated that the company was going to concurrently discover two totally different mission plans, and maintain off on making the ultimate determination about which one to really pursue till the second half of 2026.
One of many two choices would use tried-and-true strategies for touchdown on Mars demonstrated by previous rover missions, such because the “sky crane,” however would require utilizing a smaller ascent car than beforehand envisioned to get the rocks off of the planet.
The second choice would depend on business launch and touchdown capabilities that are not but totally developed, however present promise.
Every of those two choices can be “simplified, quicker, and cheaper” in comparison with the unique plan, stated NASA administrator Bill Nelson.
“We need to have the quickest, most cost-effective technique to get these 30 samples again,” stated Nelson. “We need to return 30 titanium tubes as quickly as attainable on the most cost-effective value.”
Beforehand, the Mars Pattern Return mission had been estimated to value round 11 billion {dollars} and wouldn’t return a pattern till the 2040’s, famous Nelson, who stated a re-evaluation of the mission needed to be finished as a result of “this factor had gotten uncontrolled.”
He stated that both of those two new choices would value within the vary of 6 to 7 billion {dollars} and will return a pattern by 2039.
Whereas some specialists really useful returning the samples into orbit across the moon the place they might be retrieved later, NASA officers most popular a direct return to Earth, partly as a result of “it reduces complexity,” stated Nicky Fox, affiliate administrator of NASA’s science mission directorate.
“My precedence is to discover a path ahead for Mars Pattern Return inside a balanced total science program,” stated Fox. “All of those new potentialities that we have outlined right this moment will assist us obtain that.”
As soon as the Mars rover Perseverance crew confirmed the primary pattern tube was on the floor, they checked to make certain that the tube was out of the wheels’ path.

Each of the 2 new choices into account would redesign the mission’s touchdown platform and pattern loading techniques. However every would nonetheless depend on an orbiter being constructed by the European House Company that will seize the pattern container in house close to Mars and return it to Earth.
She stated over the following 12 months or so, groups can be engaged on the engineering for every proposed plan.
This determination to pursue two separate pathways comes after the company requested proposals for decreasing the mission’s value and complexity in April, and after they lately consulted with outside experts concerning the totally different attainable ways of transferring ahead.
It is unclear what incoming president Donald Trump and his decide to move NASA, entrepreneur and personal astronaut Jared Isaacman, will consider all of this—to say nothing of Congress, which holds the purse strings.
However what is obvious is that the rocks saved on Mars are a tantalizing assortment of geologic treasures that lab scientists may seek for indicators of historic microbial life.
Whereas Mars rocks do sometimes come to Earth as meteorites, these are uncommon and have been altered by their time in house and their fiery entry by Earth’s ambiance.
Pristine Mars rocks, in distinction, may inform planetary scientists way more concerning the historical past of Mars and the probability that life developed there. That is why getting such a pattern has lengthy been a prime precedence for researchers—though they’ve additionally nervous that if prices get out of hand, the mission may draw funds away from different necessary science missions.
When the Perseverance rover launched in 2020, it carried together with it the instruments and mechanisms wanted to gather and retailer rocks. The rover landed on Mars in 2021 and shortly drilled its first rock pattern.
Since then, because the rover has trundled by the alien dust, its controllers have ordered the robotic to gather samples of significantly intriguing rocks and seal them up for safekeeping, making a carefully-curated assortment.
Whereas robotic missions have returned samples from the moon, a comet, and asteroids, no mission has ever returned rocks and dust from one other planet.
The prospect is daunting and poses technical challenges. For instance, mission planners might want to guarantee that nothing from Mars may find yourself contaminating the Earth.
Nelson famous that China was pursuing what he referred to as a “seize and go” mission to return a pattern from Mars, and that the last word choices about what NASA does will get made by officers within the incoming administration.
“I believe it was a accountable factor to do, to not hand a brand new administration only one different, in the event that they need to have a Mars pattern return, which I am unable to think about that they do not,” says Nelson. “I do not suppose we would like the one pattern return coming again on a Chinese language spacecraft.”
