The story so far:
On March 15, Elon Musk, the CEO of SpaceX, announced on X that an uncrewed Mars landing mission will take place by the end of next year. The operation is expected to feature Optimus, a robot developed by Tesla — another company owned by Mr. Musk — as its passenger. “If those landings go well, then human landings may start as soon as 2029, although 2031 is more likely,” Mr. Musk stated on X. The billionaire entrepreneur appears determined to achieve this milestone using SpaceX’s reusable super heavy-lift launch vehicle, Starship.
Is it possible?
The project has faced multiple setbacks in recent months, including two critical Starship test flight failures, or as Mr. Musk refers to them, “rapid unscheduled disassemblies”. Despite this, he has not postponed the planned date for SpaceX’s Mars mission. Originally announced in September 2024, the plan faces technical and logistical challenges, leading experts to question its feasibility.
What are some of the challenges?
One of the main concerns is whether SpaceX will be able to develop and produce a fleet of auxiliary tanker spacecraft in time and successfully refuel Starship in orbit. To reach Mars, Starship’s second stage must traverse approximately 5.5 crore kilometres in space. Timing is crucial, as every 26 months, Earth and Mars reach a “launch window” — a period when the two planets are closest, allowing for the most efficient space travel. If SpaceX fails to launch within this window, the mission could be delayed by more than two years.
Currently, Starship has only demonstrated its ability to reach Low Earth Orbit (LEO). Its fuel storage capacity of 4,200 tonnes of propellant is insufficient for a Mars journey. To address this, SpaceX announced in April 2024 that it would use LEO tanker spacecraft to refuel Starship mid-flight. However, this plan has yet to be demonstrated, and there is no clear evidence that development is underway. With only 20 months until the next launch window, it is doubtful whether anyone can design, construct, test, and deploy these tankers in time, said Daniel Dumbacher, former Deputy Associate Administrator of NASA’s Human Exploration and Operations Mission Directorate, during a U.S. Congressional hearing in February.
Beyond the issue of readiness, there is also uncertainty over whether SpaceX can manufacture and launch enough tanker spacecraft in a short time frame, given the complexity of in-orbit refuelling. This type of refuelling involves the transfer of super-cooled liquid oxygen and methane from a full tank to an empty one, operating under extreme pressure between machinery and the vacuum of space; a feat which has never been attempted before. SpaceX would need to launch and dock Starship’s multiple tankers in quick succession to offset fuel evaporation, adding another layer of difficulty to the mission.
How has SpaceX fared so far?
SpaceX has repeatedly demonstrated its ability to accomplish seemingly impossible feats. The successful deployment of reusable Falcon 9 rocket boosters and the development of the Dragon capsule have proven its capacity to design spacecraft that can withstand the harsh conditions of space.
SpaceX’s Starbase facility in Texas gives it a competitive edge, with the company reportedly manufacturing one Raptor engine per day and assembling the second stage of Starship within weeks. These production capabilities could prove essential in developing the required tanker spacecraft.
How will SpaceX land on Mars?
Given that Mr. Musk envisions Starship as a vessel for human settlement, and that the 2026 mission will carry Tesla’s Optimus robot, it appears likely that the spacecraft will attempt a surface landing. However, the current version of Starship lacks features necessary for landing, such as retractable landing gear similar to Falcon 9. While Starship has successfully landed on Earth, this was only possible with the “Chopsticks” vertical catching system, whereas no such infrastructure exists on Mars.
Additionally, Starship’s high failure rate in test flights suggests that further refinements are needed before it is considered reliable enough for such a critical mission.
What has NASA said?
The Guardian reports that senior NASA officials are worried about potential conflicts of interest between SpaceX and the Department of Governmental Efficiency (DOGE), an advisory body to U.S. President Donald Trump, which Mr. Musk heads. DOGE has been pushing for extensive federal budget cuts, leading to the shutdown of NASA’s Office of Technology, Policy, and Strategy, as well as the Office of the Chief Scientist. With these cuts, speculation has grown that more funding could be directed towards SpaceX’s contracts with NASA, raising concerns about Mr. Musk’s dual role as a government adviser and private contractor. While Mr. Musk is known for making bold claims, a successful Mars landing would solidify SpaceX’s dominance in space industry. However, whether the billionaire can overcome the technical, logistical, and political challenges ahead remains to be seen.

China is set to launch its Shenzhou-20 mission that will carry three astronauts to the Chinese space station Tiangong at 5.17 p.m. on April 24 local time (0917 GMT), state media said on Wednesday.
The main purpose of the mission is to complete the in-orbit rotation with the Shenzhou-19 crew which is scheduled to return to the Dongfeng landing site on April 29, China Manned Space Agency officials said at a press conference broadcast on CCTV.
The Shenzhou-20 spaceflight from the Jiuquan Satellite Launch Center in northwest China will carry astronauts Chen Dong, Chen Zhongrui and Wang Jie, CCTV said.
The spaceflight will be Chen Dong’s third and the first for the other two – a space engineer and a former air force pilot.
They will conduct space science and application experiments, install a space debris protection device as well as extravehicular payload and equipment, and perform recovery tasks.
The mission will also bring with it zebrafish, planarians and streptomyces as research objects to carry out three life science experiments at the space station.
The crew, scheduled to return to the earth in late October, can expect a resupply mission via the unmanned Tianzhou-9 cargo spacecraft.
The country’s fourth batch of astronauts set to participate in Shenzhou spaceflights is currently in training, featuring for the first time astronauts from China’s special administrative regions of Hong Kong and Macau, as well as Pakistan.
The Hong Kong and Macau astronauts are likely to carry out their first mission as early as 2026, state media reported.
China said the selection of the Pakistani astronauts is underway. Both countries signed an agreement for space cooperation in February.
One of the two Pakistani astronauts that will join the Chinese missions is set to focus on payloads and scientific research aboard China’s space station.
