Confirming rumors and suspicions that SpaceX is adjusting its plans to begin dispatching robotic landers to Mars, NASA officials said the commercial space company has informed the agency that it has put its Red Dragon program on the back burner.
Under the terms of a Space Act Agreement between NASA and SpaceX, the government agreed to provide navigation and communications services for the Red Dragon mission, which originally aimed to deliver an unpiloted lander to Mars in 2018. SpaceX confirmed earlier this year the launch of the experimental lander on a Falcon Heavy rocket had slipped to 2020. But Elon Musk, SpaceX's founder and chief executive, said last month that the company is redesigning its next-generation Dragon capsule, a craft designed to carry astronauts to the International Space Station, to do away with the capability for propulsive, precision helicopter-like landings as originally envisioned. Returning space crews will instead splash down in the ocean under parachutes.
[...] Musk wrote in a tweet that SpaceX has not abandoned supersonic retro-propulsion at Mars. "Plan is to do powered landings on Mars for sure, but with a vastly bigger ship," he tweeted last month after the announcement that SpaceX is omitting the propulsive landing capability on the Crew Dragon.
Musk said his team at SpaceX is refining how the company could send people to Mars, eventually to settle there. He revealed a Mars transportation architecture in a speech at the 67th International Astronautical Congress in Guadalajara, Mexico, last year, but the outline has since changed. A vision for gigantic interplanetary transporters Musk presented last year has been downsized, he said. Musk said he will unveil the changes during a presentation in September at this year's International Astronautical Congress in Adelaide, Australia.
Writing on Popular Science, Sarah Fecht says:
In 2018, SpaceX could become the first private company to land its own spacecraft on Mars. But it doesn't plan to do so alone. NASA wants to see if SpaceX's landing tech could put astronauts on Mars, and to find out, its vowed to help the private company send an uncrewed capsule to the Red Planet.
Summarizing an article from SpaceFlightNow, she continues:
While SpaceX would fund and build the uncrewed Red Dragon capsule and the Falcon Heavy rocket it launches on, NASA would take a supportive role in the mission, providing communications through the Deep Space Network--a mesh of telescopes around the world that keeps NASA in constant contact with all its spacecraft, despite the Earth's spinning.
NASA will also help locate a landing site for the Red Dragon, Spaceflight Now reports, and will help to prevent Earth microbes from hitching a ride on the Red Dragon and contaminating Mars.
All told, NASA estimates it'll spend about $32 million dollars on the mission--quite a bargain, considering the space agency hopefully get a new landing technology out of it. The Red Dragon would fire retrothrusters to attempt a soft landing on Mars--something that's never been attempted before for such a large spacecraft. SpaceX is expecting to spend about $300 million on it.
By contrast, NASA spent $2.5 billion on the Curiosity rover and its novel "sky crane" landing method. If all goes well, the Red Dragon mission will pave the way to put people on Mars, either by NASA or SpaceX.
Elon Musk has published a plan to colonize Mars using as many as 1,000 Interplanetary Transport System spaceships to transport a million settlers at a cost of $200,000 per person:
Elon Musk has put his Mars-colonization vision to paper, and you can read it for free.
SpaceX's billionaire founder and CEO just published the plan, which he unveiled at a conference in Mexico in September 2016, in the journal New Space. Musk's commentary, titled "Making Humanity a Multi-Planetary Species," is available for free [DOI: 10.1089/space.2017.29009.emu] [DX] on New Space's website through July 5.
"In my view, publishing this paper provides not only an opportunity for the spacefaring community to read the SpaceX vision in print with all the charts in context, but also serves as a valuable archival reference for future studies and planning," New Space editor-in-chief (and former NASA "Mars czar") Scott Hubbard wrote in a statement.
[...] ITS rockets will launch the spaceships to Earth orbit, then come back down for a pinpoint landing about 20 minutes later. And "pinpoint" is not hyperbole: "With the addition of maneuvering thrusters, we think we can actually put the booster right back on the launch stand," Musk wrote in his New Space paper, citing SpaceX's increasingly precise Falcon 9 first-stage landings.

In recent weeks, there have been rumors that SpaceX is no longer planning to send an uncrewed version of its Dragon spacecraft to Mars in 2020, or later. Now those rumors about the Red Dragon concept have been largely confirmed.
The company had planned to use the propulsive landing capabilities on the Dragon 2 spacecraft—originally developed for the commercial crew variant to land on Earth—for Mars landings in 2018 or 2020. Previously, it had signed an agreement with NASA to use some of its expertise for such a mission and access its deep-space communications network.
On Tuesday, however, during a House science subcommittee hearing concerning future NASA planetary science missions, Florida Representative Bill Posey asked what the agency was doing to support privately developed planetary science programs. Jim Green, who directs NASA's planetary science division, mentioned several plans about the Moon and asteroids, but he conspicuously did not mention Red Dragon.
After this hearing, SpaceX spokesman John Taylor didn't return a response to questions from Ars about the future of Red Dragon.
So the real question becomes how DO they plan to land it?
It was about a year ago that Boeing Chief Executive Dennis Muilenburg first began saying his company would beat SpaceX to Mars. "I'm convinced that the first person to step foot on Mars will arrive there riding on a Boeing rocket," he said during a Boeing-sponsored tech summit in Chicago in October 2016.
On Thursday, Muilenburg repeated that claim on CNBC. Moreover, he added this tidbit about the Space Launch System rocket—for which Boeing is the prime contractor of the core stage—"We're going to take a first test flight in 2019 and we're going to do a slingshot mission around the Moon."
Unlike last year, Muilenburg drew a response from SpaceX this time. The company's founder, Elon Musk, offered a pithy response on Twitter: "Do it."
The truth is that Boeing's rocket isn't going anywhere particularly fast. Although Muilenburg says it will launch in 2019, NASA has all but admitted that will not happen. The rocket's maiden launch has already slipped from late 2017 into "no earlier than" December 2019. However, NASA officials have said a 2019 launch is a "best case" scenario, and a slip to June 2020 is more likely.
Also, the next SpaceX flight is an ISS resupply mission and is scheduled for this coming Tuesday (December 12, 2017) at 1646 GMT (11:46 a.m. EST) from SLC-40, Cape Canaveral Air Force Station, Florida. The plan is for the booster to return to landing at Landing Zone-1, also at Cape Canaveral.
