SpaceX’s Starship, the most important rocket on the planet, will get even greater as the corporate continues to focus on Mars missions sooner or later.
Elon Musk, the billionaire founding father of SpaceX, instructed workers on April 4 that Starship will ultimately be as tall as 500 toes (150 meters), roughly 20 p.c increased than the huge system aboard the Tremendous Heavy rocket proper now.Â
What’s extra, advances in reusability may have every launch price roughly $3 million every, Musk predicted; that is lower than a 3rd of what a (a lot smaller) Falcon 1 rocket launch price in 2004 when inflation is taken into consideration. (The determine 20 years in the past was $5.9 million, in line with NBC, which is roughly $9.5 million in 2024 {dollars}.)Â
“These are kind of unthinkable numbers,” Musk stated within the Starship replace, launched publicly April 6, roughly one month after the third and final check flight so far. “No person ever thought that this was attainable, however we’re not breaking any physics to attain this. So that is inside the bounds, with out breaking physics. We are able to do that.”

Musk tends to ship Starship updates not less than every year to focus on progress the corporate is making towards its long-term plans of settling Mars. Certainly, the final yr has seen three Starship launches, so there was progress made not too long ago. Musk did not, nevertheless, tackle delays in launching Starship which have contributed to pushing again the launch date for the primary moon touchdown beneath the NASA-led Artemis program.
SpaceX was named the seller for the Artemis 3 touchdown mission that, till not too long ago, was set for 2025. In January, NASA elected to carry the launch date one other yr, to 2026, resulting from a variety of technical points. Apart from Starship not being prepared — the company desires many profitable launches earlier than approving it for astronaut flights — Artemis 3 was additionally delayed resulting from sluggish progress on spacesuits and issues with the mission’s Orion spacecraft, amongst different elements.
Nonetheless, Musk’s phrases about Artemis, to workers, centered on Starship’s future capabilities: orbiting the Earth and refilling its tanks, each of which have but to be confirmed on its three check flights.
“It will … be essential for the Artemis program for the NASA to get again to the moon,” Musk stated of these capabilities. He additionally envisions a “Moon Base Alpha” that would come with ships “specialised for going to and from the moon”, which means there could be no warmth defend or flaps as a result of lack of environment.

Musk’s 45-minute speech touched on the same old themes for his Crimson Planet updates, specializing in easy methods to ship lots of cargo on the market for eventual settlers. He famous that might take 1000’s of launches to do; for perspective, Musk stated the corporate has accomplished 327 profitable Falcon sequence launches and about 80 p.c of these had reused boosters (a key think about lowering price.)
SpaceX is by far probably the most lively launching entity on Earth, and Musk forecasts the corporate will ship roughly 90 p.c of orbital mass aloft this yr in comparison with China’s 6 p.c (the second-largest entity.)Â
Starship’s subsequent and fourth spaceflight try, anticipated to happen in Might, goals to have the primary stage of Tremendous Heavy land “on primarily a digital tower” within the Gulf of Mexico, Musk stated. As soon as the corporate safely will get that finished, they are going to think about using the launching space at Starbase, in south Texas, for future landings as quickly as Flight 5. (Musk pegged the probabilities of success on Flight 4 at 80% or 90%.)
Musk additionally desires to carry out two splashdowns of the higher stage of Starship in a row, in a managed style, earlier than sending it to Starbase on a future flight. “We don’t need to rain particles over Mexico or the U.S.,” he stated. “My guess might be subsequent yr when we will reuse Starship.”
General, Musk plans for a number of Starship launches to happen this yr, and suggests SpaceX will construct an extra six spacecraft by the top of 2024. A brand new rocket manufacturing facility for the corporate ought to be out there in 2025, which might make manufacturing even sooner.Â
Future variations of Starship will embrace a “Starship 2” to ship 100 tons of payload to low-Earth orbit and the 500-foot “Starship 3” for 200 or extra tons. Greater autos, Musk confused, will imply fewer (4 or 5) refueling missions in low Earth orbit to get a Starship prepared for the journey to Mars sometime.Â
Of those milestones, Musk stated it will be “very a lot a success-oriented schedule.” His speech didn’t point out the Federal Aviation Administration, which should approve every one of many launches, nor ongoing criticism of the environmental influence of Starship on the ecologically delicate space close to Starbase.
That influence could proceed to develop, as Musk stated it will take roughly 10 launches a day to ship lots of of autos to Mars each two years (when the planet is closest) to make a long-term settlement possible. As for the variety of Mars-bound individuals, that might be roughly 1,000,000 people, he stated — that matches predictions he made not less than way back to 2017. Musk additionally says he desires to get the settlement going “in 20 years.” He stated the identical factor in 2011.
