  • Boeing’s Starliner Is Finally Ready to Launch a NASA Crew Into Space

    Boeing’s Starliner Is Finally Ready to Launch a NASA Crew Into Space

    “It fits in with the general narrative of Boeing having lost its way,” says McDowell.

    Starliner, like Crew Dragon, is a capsule-shaped spacecraft like the Apollo missions of old. Capable of carrying up to seven astronauts, the spacecraft is largely autonomous, requiring major input only in the event of an emergency. During the test mission beginning tonight, Wilmore and Williams will test out this eventuality, purposefully pointing the spacecraft off course to ensure they can manually get it back on track, as well as assessing the spacecraft’s general life support and navigation systems. While docked to the space station the vehicle will be put through further tests, including practising using it as a lifeboat in case astronauts needed to evacuate the ISS.

    Starliner is reusable, with Boeing saying it can be flown on up to 10 missions. The spacecraft sports no toilet—unlike Crew Dragon—and has about the same liveable volume as an SUV, making for a relatively cozy rise to and from orbit. It has physical hand controls and switches for the astronauts to control the spacecraft, unlike the touch screens used inside Crew Dragon. On its return home, a heat shield keeps the occupants safe from temperatures of some 3,000 degrees Fahrenheit, before the vehicle descends under parachute and finally touches down, with the help of air bags to cushion the fall, in one of several desert landing sites in the US.

    Boeing is contracted with NASA to launch Starliner six times to the ISS after this test mission, each time carrying four or five astronauts along with cargo for six-month stays aboard the station. The spacecraft will alternate its missions with Crew Dragon, one launching around February and one around August each year. Having that redundancy is hugely beneficial, says NASA’s Steven Siceloff, public affairs specialist at NASA’s Kennedy Space Center. “This way, if a technical issue does come up with one vehicle, it does not mean that the space station is on its own for a while,” he says. “It means that there’s alternatives.”

    Laura Forczyk, founder of the space consulting firm Astralytical, notes that redundancy is “especially important now because of the unreliability of Russia.” NASA and the Russian space agency, Roscosmos, continue to cooperate on the ISS program for now, including sharing seats between Russia’s Soyuz vehicle, Crew Dragon, and now Starliner, despite the embittered political situation between the two nations.

    But beyond these six missions Boeing currently has no publicized flights planned for Starliner. “If this was SpaceX, you’d already have Musk talking about three or four contracts that he had in line with famous people,” says McDowell. With the ISS also set to be deorbited in 2030, this could mean Starliner—despite a decade of development and billions of dollars spent—faces the prospect of flying only a handful of times. “We don’t know whether Boeing has the capacity to do additional commercial missions at this time,” says Forczyk.

    NASA has been trying to spur the development of new commercial space stations, in the same manner as this commercial crew program, in the hopes they can fill the orbital research void left when the ISS ends. These commercial stations could be destinations for Starliner and Crew Dragon, if they come to fruition, but the exact appetite for this endeavor remains uncertain for now. “Is there enough of a market to sustain two entities doing this?” says McDowell. “I remain skeptical of commercial space stations. But if they do succeed, you’re going to want multiple options to get up and down.”

    Before it grapples with that future, Boeing will simply be hoping for a smooth and successful first crewed flight of Starliner. Once it’s finally in the skies with humans on board, the spacecraft can start to play the role it has long been touted for.

  • Elon Musk’s Latest Mars Pitch Has Potential

    Elon Musk’s Latest Mars Pitch Has Potential

    [ad_1]

    Elon Musk has been talking publicly about his sweeping vision for Mars settlement for nearly eight years now, dating to a speech in Guadalajara, Mexico, in September 2016.

    This weekend, at SpaceX’s Starbase facility in South Texas, Musk once again took up the mantle of his “making life multiplanetary” cause. Addressing employees at the location of the company’s Starship factory, Musk spoke about the “high urgency” needed to extend the “light of consciousness” beyond Earth. That is not because humanity’s home planet is a lost cause or should not be preserved. Rather, Musk said, he does not want humanity to remain a one-planet civilization that will, inevitably, face some calamity that will end the species.

    All of this is fairly familiar territory for spaceflight enthusiasts—and observers of Musk. But during the past eight years he has become an increasingly controversial and polarizing figure. Based on his behavior, many people will dismiss Musk’s Mars comments as those of a megalomaniac. At least in regard to spaceflight, however, that would be wrong. Musk’s multiplanetary ambitions today are more credible because SpaceX has taken steps toward doing what he said the company would do.

    SpaceX has real hardware today and has completed three test flights. A fourth is possible next month.

    “It’s surreal, but it’s real,” Musk said this weekend, describing the audacious Mars vision.

    The Booster and Ship

    As part of his 45-minute speech, Musk spoke about the booster for Starship, the upper stage, and the company’s plans to ultimately deliver millions of tons of cargo to Mars for a self-sustaining civilization.

    If thousands of launches seem impossible, Musk noted that SpaceX has completed 327 successful Falcon launches and that 80 percent of those have involved used boosters. This year, he said, SpaceX will launch about 90 percent of the mass sent into orbit from the planet. China will launch about 6 percent, he added, with the remainder of the world accounting for the other 4 percent.

    This kind of performance has given Musk confidence that reusability can be achieved with the Super Heavy booster that powers Starship. On the vehicle’s next test flight, possibly in May, the company will attempt to land the booster on a virtual tower in the Gulf of Mexico. If that landing is precise enough, SpaceX will try to catch the booster on the fifth test flight with the chopstick-like mechanisms on Starship’s massive launch tower.

    “That’s very much a success-oriented schedule, but it is within the realm of possibility,” Musk said. With multiple test flights occurring this year, Musk said the odds of catching the booster with the launch tower this year are 80 to 90 percent.

    It will take longer to land and begin reusing Starship’s upper stage, which must survive the fiery reentry through Earth’s atmosphere. This vehicle broke apart and burned up during its attempt to return through the atmosphere during a flight test in March. On the next flight, Musk said, the goal for Starship’s upper stage is to survive this heating and make a controlled landing in the ocean. At some point this year, he expects SpaceX to achieve this milestone and then begin landing Starships back in Texas next year.

    Building More, Building Bigger

    SpaceX is also building additional ground-based infrastructure and making design upgrades to Starship.

    Musk said the company will construct a second launch tower in Texas to facilitate additional developmental test flights. And by the end of 2025 it intends to have two Starship launch towers in Florida to begin supporting operational launches. Initially, these are likely to support Artemis lunar landing missions for NASA.

    When SpaceX’s Starship rocket launched for the first time in 2023, it destroyed its launch pad in an explosion similar to a volcanic eruption that sent huge chunks of concrete high into the sky. Understanding the blast in detail could help us design more robust launch and landing pads for future missions to the moon and Mars.

    “It was eye-opening to us that launch pads could explode so violently,” says Philip Metzger

    Starship launch 3: What time is the SpaceX flight today?

    SpaceX's Starship prepped for flight

    SpaceX’s Starship prepped for flight

    SpaceX

    SpaceX is launching its massive Starship rocket for the third time on 14 March, following two failed missions. Here is everything you need to know about it.

    What is Starship?

    Starship is the most powerful rocket ever built. It is 121 metres long and its reusable booster can land safely after taking the second stage to an altitude of more than 70 kilometres. That second stage is also reusable, which is intended to make Starship an affordable, reliable vehicle capable of quickly turning around and relaunching. The ultimate aim of the project is to put humans on the moon and, later, Mars.

    What time is Starship blasting off?

    SpaceX has announced that livestream video of the launch will begin at 8.25am local time in Texas, which is 13.25 GMT. The actual launch is expected to happen about 30 minutes after the livestream begins.

    Where is Starship going?

    This launch is, as you would expect, the most ambitious so far. SpaceX is aiming to carry out a successful first and second stage launch, taking Starship into space, where it will open and close its payload door as a test, shuffle fuel from one tank to another as a first step towards the eventual refuelling of one Starship by another – which will be vital for long-range missions – and relight its engines for a controlled re-entry to Earth’s atmosphere.

    This launch will follow a new trajectory that will see the second stage splash down in the Indian Ocean. While it is designed to be a reusable craft, this mission aims to have it make a slow and controlled landing on the ocean rather than on land or a ship. This is easier and safer at this stage of development.

    What happened when Starship launched before?

    There have been two Starship launches, both ending in failure, although that is an expected part of SpaceX’s fail-fast, learn-fast strategy.

    The first launch on 20 April last year saw three engines on the first stage – from a total of 33 – fail to ignite. Several more subsequently failed during the flight. The rocket then span out of control, causing a self-destruct safeguard to kick in, something that SpaceX sardonically calls a rapid unscheduled disassembly (RUD). The whole flight lasted around 3 minutes and reached a maximum altitude of 39 kilometres.

    Starship’s second launch was on 18 November. This time, all 33 engines fired and the rocket flew long enough for the first and second stages to separate. But, as the first stage rotated to begin its slowdown and landing procedure, it exploded. The second stage successfully continued to an altitude of about 149 kilometres – passing the Kármán line that marks the beginning of space – but a safeguard feature destroyed it when it stopped sending back data, before it had a chance to complete an orbit or make its way back to Earth.

    What happens if this launch goes wrong?

    It probably will go wrong, in some respect. It is highly unlikely that Starship will complete its mission flawlessly. But any failure will supply data and experience that can be used to improve the design and processes for the fourth launch. SpaceX has so far shown that it can iterate rapidly and make big progress with every launch.

  • SpaceX Launched Military Satellites Designed to Track Hypersonic Missiles

    SpaceX Launched Military Satellites Designed to Track Hypersonic Missiles

    [ad_1]

    Two prototype satellites for the Missile Defense Agency and four missile-tracking satellites for the US Space Force rode a SpaceX Falcon 9 rocket into orbit Wednesday from Florida’s Space Coast.

    These satellites are part of a new generation of spacecraft designed to track hypersonic missiles launched by China or Russia and perhaps emerging missile threats from Iran or North Korea, which are developing their own hypersonic weapons.

    Hypersonic missiles are smaller and more maneuverable than conventional ballistic missiles, which the US military’s legacy missile defense satellites can detect when they launch. Infrared sensors on the military’s older-generation missile tracking satellites are tuned to pick out bright thermal signatures from missile exhaust.

    The New Threat Paradigm

    Hypersonic missiles represent a new challenge for the Space Force and the Missile Defense Agency (MDA). For one thing, ballistic missiles follow a predictable parabolic trajectory that takes them into space. Hypersonic missiles are smaller and comparatively dim, and they spend more time flying in Earth’s atmosphere. Their maneuverability makes them difficult to track.

    A nearly 5-year-old military organization called the Space Development Agency (SDA) has launched 27 prototype satellites over the last year to prove the Pentagon’s concept for a constellation of hundreds of small, relatively low-cost spacecraft in low-Earth orbit. This new fleet of satellites, which the SDA calls the Proliferated Warfighter Space Architecture (PWSA), will eventually number hundreds of spacecraft to track missiles and relay data about their flight paths down to the ground. The tracking data will provide an early warning to those targeted by hypersonic missiles and help generate a firing solution for interceptors to shoot them down.

    The SDA constellation combines conventional tactical radio links, laser inter-satellite communications, and wide-view infrared sensors. The agency, now part of the Space Force, plans to launch successive generations, or tranches, of small satellites, each introducing new technology. The SDA’s approach relies on commercially available spacecraft and sensor technology and will be more resilient to attack from an adversary than the military’s conventional space assets. Those legacy military satellites often cost hundreds of millions or billions of dollars apiece, with architectures that rely on small numbers of large satellites that might appear like a sitting duck to an adversary determined to inflict damage.

    Four of the small SDA satellites and two larger spacecraft for the Missile Defense Agency were aboard a SpaceX Falcon 9 rocket when it lifted off from Cape Canaveral Space Force Station at 5:30 pm EST (2230 UTC) Wednesday.

    The rocket headed northeast from Cape Canaveral to place the six payloads into low-Earth orbit. Officials from the Space Force declared the launch a success later Wednesday evening.

    The SDA’s four tracking satellites, built by L3Harris, are the last spacecraft the agency will launch in its prototype constellation, called Tranche 0. Beginning later this year, the SDA plans to kick off a rapid-fire launch campaign with SpaceX and United Launch Alliance to quickly build out its operational Tranche 1 constellation, with launches set to occur at one-month intervals to deploy approximately 150 satellites. Then, there will be a Tranche 2 constellation with more advanced sensor technologies.

    The primary payloads aboard Wednesday’s launch were for the MDA. These two Hypersonic and Ballistic Tracking Space Sensor (HBTSS) satellites, one supplied by L3Harris and the other by Northrop Grumman, will demonstrate medium field-of-view sensors. Those sensors can’t cover as much territory as the SDA satellites but will provide more sensitive and detailed missile tracking data.

    SpaceX is getting ready to launch its huge Starship rocket for the third time. But the exact launch date won’t be announced until the US government’s Federal Aviation Administration (FAA) finishes investigating why the last launch – in November 2023 – failed to reach orbit.

    The Starship rocket’s first test launch in April 2023 saw it spin out of control because of problems with several of its engines. Those faults activated an automated flight termination system designed to safely blow up the rocket. It failed to do so, and the rocket continued to tumble before disintegrating. It did not make it to space.

    The incident damaged the launchpad and blasted debris across huge swathes of the surrounding area. After repairs and updates were made to the launch facility and the FAA certified enough had been done to prevent similar damage from occurring again, SpaceX initiated its second Starship test launch in November 2023.

    That one didn’t go well, either. For a few minutes everything seemed fine. The rocket made it to space – but then the engines started failing and it blew up. Now, SpaceX has to build a new rocket, and the FAA has to give it a licence to fly it.

    “We’re expecting that licence to come in February. So it’s looking like [flight] three will occur in February of this year,” SpaceX official Jessica Jensen said in a press conference on 9 January.

    Eventually, Starship is intended to ferry astronauts to and from the surface of the moon. NASA selected it as the vehicle for its Artemis III and IV missions, planned for 2026 and 2028. The enormous rocket could even carry astronauts to Mars as soon as 2029, SpaceX CEO Elon Musk has said. But before it can do any of that, Starship will have to make it to space without exploding or falling apart, making its third flight a crucial test.
