Mars sample-return mission gets boost from Trump’s 2021 budget request
On Monday, Feb. 10, the White House released its 2021 federal budget request, and in it, the administration identified NASA’s Mars sample return plans as a top priority. It also earmarked funding for a future mission to map out where ice is located on Mars.
The request asks for $25.2 billion for NASA, which is roughly a 12% boost over what the agency’s current budget is.
Of that $25.2 billion, Trump has designated $233 million for “Mars Future Missions” — one of which hopes to transport pristine pieces of the Red Planet to Earth, sometime around the 2031 time frame.
“Mars Future supports the development of the Mars Sample Return (MSR) mission that is planning to enter formulation (Phase A) as early as the summer of FY 2020,” NASA officials wrote in a description of the agency’s proposed 2021 allocation.
“In FY 2021, MSR formulation activities include concept and technology development, and early design and studies in support of the Sample Return Lander and the Capture/Containment and Return System,” they added. “Mars Future also supports a study of the facility required for handling of returned samples.”

The samples NASA is referring to will be collected by NASA’s next Mars rover, which is scheduled to launch in July. Dubbed the Mars 2020 rover, the six-wheeled robot will land on Mars in Feb. 2021, touching down inside Jezero Crater. It’s goal: to look for signs of life, and to collect samples of Mars for future return to Earth.
The rover, which will receive an official name sometime in March, will bag and tag samples of rocks and dirt, sealing them in canisters for eventual return to Earth. Once they arrive here, scientists all around the world will be able to study the samples and better understand our celestial neighbor.
The sample return part of the mission is a collaboration between NASA and the European Space Agency (ESA). It will be a multi-step process, which includes the launch of NASA’s Sample Return Lander (SRL) followed by ESA’s Earth Return Orbiter (ERO).
The logistics are still being finalized as NASA is looking for a director to lead the program. But a rough outline of the planned return can be broken down as follows:
NASA’s sample return vehicle will carry a small rocket called the Mars Ascent Vehicle (MAV) along with an ESA-built rover, called the Sample Fetch Rover (SRF). The SRF will seek out the samples collected by the 2020 rover, and haul them to the MAV.
From there, the MAV will then launch the samples into orbit around Mars; there they’ll be picked up by the ERO, and the craft will head back toward Earth. Once in close proximity to Earth, the ERO will jettison the container, and it will land in the Utah desert. NASA expects this to all happen around 2031, although none of the dates are official at this point.
Also outlined in the budget is a need for a Sampling Receiving Facility, where the precious bits of Mars will be handled with the utmost care. In the facility, scientists will catalog the samples, and make sure that there’s no cross-contamination with Earth particles. (And to ensure that if there is life on Mars, no little Martian microbes will get out into the environment.)

But that’s not all, the “Mars Future Missions” budgetary line also allows for a collaboration with Canada to create the Mars Ice Mapper. Detailed information on this project is scarce at the moment as it’s in its very early stages.
“The Mars Ice Mapper is a remote sensing mission under study intended to map and profile the near-surface (3-15 meters) water ice, particularly that which lies in the mid-latitude regions, in support of future science and exploration missions,” NASA officials wrote in the budget document.
The Mars Ice Mapper could be a preliminary step in the effort to put humans on Mars, a goal NASA aims to accomplish sometimes in the 2030’s.
The 2021 budget request allocates more money to future Mars missions than previous budgets have, lining up with NASA’s overall goal of sending astronauts to both the moon and Mars.
If this budget request is any indication, the “Mars Future Missions” programs could set their budgets steadily increased as the years progress. But it’s not set in stone. The request is just that, a request. Congress has the ultimate approval and could choose to fund everything as it, or shuffle things around. Let’s hope it’s the latter so valuable programs, like STEM engagement, Earth science missions, and an incredible telescope are not cancelled.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Elon Musk sends first warning to SpaceX short sellers
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.

— Elon Musk (@elonmusk) July 17, 2026
Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.

SpaceX adjusts Starship Flight 13 test launch target date once again
SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.
The target flight was initially rescheduled for today, but SpaceX pushed it back again.
This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.
SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.
This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.
Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.
Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.
For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.
Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.
The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.
This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.
