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 has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
-
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.

SpaceX and Nvidia team up on Musk’s orbital AI bet
SpaceX revealed a new Nvidia satellite partnership, then Musk pledged an exclusive Nvidia hardware commitment.
SpaceX and Nvidia are now working together on the hardware that will power Musk’s orbital data center ambitions. SpaceX announced on X on Tuesday that it is partnering with Nvidia to design the compute payload for Starmind AI1, the first satellite in a planned constellation built to run AI workloads directly in orbit. Each Starmind satellite will carry Nvidia’s Rubin GPUs and Vera CPUs, according to the post, which included renderings of the payload design.
The announcement landed hours before SpaceX’s first earnings call as a public company, where Musk went further, saying the company has committed to building its AI infrastructure exclusively on Nvidia hardware. “We think the Vera Rubin architecture is the best architecture. We think it’s the best AI computer, and we greatly value our close cooperation and partnership on many levels with Nvidia,” Musk told investors on the call,. “So we’re exclusive to Nvidia.”
Musk said SpaceX plans to deploy Nvidia’s Vera Rubin NVL72 rackscale system, codenamed Kyber, both on the ground and in space. He set a target of 2 gigawatts of compute capacity online by the end of this year, scaling to roughly 10 gigawatts by the end of 2027.
SpaceX’s newest Starmind will make earth data centers obsolete
Starmind has been in development since Musk confirmed the name in June, following an xAI trademark filing that tipped off the project before SpaceX made it official. The idea is massive in scope and instead of moving data down to ground based servers, satellites equipped with onboard processors and large solar arrays would compute AI workloads in orbit and beam results back to Earth. SpaceX has already filed with the FCC for a constellation of up to one million satellites to support the effort, citing constant solar power and the absence of zoning restrictions as advantages over terrestrial data centers.
The Nvidia exclusivity marks a shift in tone from just two weeks ago, when Musk was busy knocking down a report that SpaceX had ordered $52 billion worth of Nvidia GPUs through Foxconn, calling it fake news at the time. The dollar figure in that rumor may have been wrong, but the underlying direction seems correct. SpaceX’s AI division already leases Colossus compute capacity to Anthropic and Google, and Tuesday’s earnings report showed AI revenue climbing sharply as those deals ramp up.
Nvidia shares rose roughly 3% in Tuesday trading on the news, while SpaceX stock climbed nearly 9% during the day before giving back gains after hours as investors digested the earnings report’s capital spending figures.

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.
