SpaceX Launches And Lands Starship Mars Prototype In Major First, Before It Explodes Again
|
|
In a major milestone, Elon Musk’s company SpaceX has successfully landed its Starship vehicle from high-altitude for the first time, as it continues its efforts to launch humans to Mars.
But it experienced a dramatic explosion shortly after landing.
Today, Wednesday, March 3 at 6.14 P.M. Eastern Time, the company’s latest Starship prototype lifted off from the company’s test site in Boca Chica, Texas.
The methane-powered rocket, designed to one day carry humans but uncrewed on this launch, then used its three Raptor engines to climb to a height of around 10 kilometers.
After a brief hover the vehicle then began its descent back to Earth, flipping to perform a horizontal “belly flop” and simulate a future return from space.
The vehicle lifted off as planned once again.

As it approached the ground, it flipped back to a vertical position and reignited its engines to attempt a landing.
In the past few months, the company has tried and failed to launch and land Starship on two high-altitude tests, with those previous SN8 and SN9 prototypes crash-landing on both occasions.
This time, however, everything went relatively smoothly. Slightly more than six minutes after launching, the vehicle was back safely on Earth – heralding a crucial step in a new era of human spaceflight.
“Third time’s the charm!” SpaceX engineer John Insprucker commentated in the company’s live stream of the flight.
You can rewatch the action unfold below.
However, about 10 minutes after landing, when SpaceX’s live stream had ended, the vehicle was caught on camera by other observers suddenly exploding.
The cause of this subsequent explosion is not yet clear.
It did appear that the vehicle did not properly deploy its landing legs for the touchdown, while a small fire also broke out at its base after the landing.
And so, while the test itself will be deemed a success, there are clearly a few issues that still need to be ironed out with the vehicle.
Starship is SpaceX’s 50-meter tall reusable experimental vehicle designed to one day take humans to Mars and other destinations in the Solar System.
It will launch on top of a large reusable booster called Super Heavy, the two of them stacking up to 120 meters high, for launches to space from Earth.
Together they would be the largest rocket ever flown in history.
SN10 touched down, although its landing legs didn’t appear to deploy properly.
SpaceX
In order to reach that goal, SpaceX has been building Starship prototypes in increasing complexity, with today’s flight being “serial number 10” – or SN10.
Their last launch, SN9, saw the vehicle launch and climb to about 12 kilometers before falling back to Earth, ultimately exploding on the ground in a failed landing attempt.
But Musk has been very vocal about how these prototypes are designed to potentially fail, as the company focuses more on rapid iterations than perfecting each one.
SN10, however, seemed to go almost entirely as planned.
About 10 minutes after landing, the vehicle suddenly exploded.
SpaceX
“The key point of today’s test flight was to gather data on controlling the vehicle while re-entering, and we were successful in doing so,” said Insprucker.
“We had a nominal ascent, we had a maneuver to place Starship horizontal, and during the subsonic entry it appears we had good control on re-entry using the front and aft flaps.
“As we approached the landing pad, we successfully lit the three Raptor engines to perform that flip maneuver, and then we shut down two of them and landed on a single engine as planned.
“A beautiful soft landing of Starship on the landing pad of Boca Chica.”
Few, despite the subsequent explosion, could argue with that.
Now, SpaceX will continue with its testing phase, as it moves towards launching Starship to space for the first time later this year.

OTTAWA (Reuters) – Canada’s Telesat is racing to launch a low-earth-orbit (LEO) satellite constellation to provide high-speed global broadband from space, pitting the satellite communications firm founded in 1969 against two trailblazing billionaires, Elon Musk and Jeff Bezos.
Musk, the Tesla Inc CEO who was only a year old when Telesat launched its first satellite, is putting the so-called Starlink LEO into orbit with his company SpaceX, and Amazon.com Inc, which Bezos founded, is planning a LEO called Project Kuiper. Bezos also owns Blue Origin, which builds rockets.
Despite the competition, Dan Goldberg, Telesat’s chief executive officer, voices confidence when he calls Telesat’s LEO constellation “the Holy Grail” for his shareholders – “a sustainable competitive advantage in global broadband delivery.”
Telesat’s LEO has a much lighter price tag than SpaceX and Amazon’s, and the company has been in satellite services decades longer. In addition, instead of focusing on the consumer market like SpaceX and Amazon, Telesat seeks deep-pocketed business clients.
Goldberg said he was literally losing sleep six years ago when he realized the company’s business model was in peril as Netflix and video streaming took off and fiber optics guaranteed lightning-fast internet connectivity.
Telesat’s 15 geostationary (GEO) satellites provide services mainly to TV broadcasters, internet service providers and government networks, all of whom were growing increasingly worried about the latency, or time delay, of bouncing signals off orbiters more than 35,000 km (22,200 miles) above earth.
Then in 2015 on a flight home from a Paris industry conference where latency was a constant theme, Goldberg wrote down his initial ideas for a LEO constellation on an Air Canada napkin.
Those ideas eventually led to Telesat’s LEO constellation, dubbed Lightspeed, which will orbit about 35 times closer to earth than GEO satellites, and will provide internet connectivity at a speed akin to fiber optics.
Telesat’s first launch is planned in early 2023, while there are already some 1,200 of Musk’s Starlink satellites in orbit.
“Starlink is going to be in service much sooner … and that gives SpaceX the opportunity to win customers,” said Caleb Henry, a senior analyst at Quilty Analytics.
Starlink’s “first mover” advantage is at most 24 months and “no one’s going to lock this whole market up in that amount of time,” Goldberg said.
Telesat in 2019 signed a launch deal with Bezos’ aerospace company Blue Origin. Discussions are ongoing with three others, said David Wendling, Telesat’s chief technical officer.
They are Japan’s Mitsubishi Heavy Industries Ltd, Europe’s ArianeGroup , and Musk’s SpaceX, which launches the Starlink satellites. Wendling said a decision would be taken in a matter of months.
Telesat aims to launch its first batch of 298 satellites being built by Thales Alenia Space in early 2023, with partial service in higher latitudes later that same year, and full global service in 2024.
‘SWEET SPOT’
The Lightspeed constellation is estimated to cost half as much as the $10 billion SpaceX and Amazon projects.
“We think we’re in the sweet spot,” Goldberg said. “When we look at some of these other constellations, we don’t get it.”
Analyst Henry said Telesat’s focus on business clients is the right one.
“You have two heavyweight players, SpaceX and Amazon, that are already pledging to spend $10 billion on satellite constellations optimized for the consumer market,” he said. “If Telesat can spend half that amount creating a high-performance system for businesses, then yeah, they stand to be very competitive.”
Telesat’s industry experience may also provide an edge.
“We’ve worked with many of these customers for decades … That’s going to give us a real advantage,” Goldberg said.
Telesat “is a satellite operator, has been a satellite operator, and has both the advantage of expertise and experience in that business,” said Carissa Christensen, chief executive officer of the research firm BryceTech, adding, however, that she sees only two to three LEO constellations surviving.
Telesat is nailing down financing – one-third equity and two-thirds debt – and will become publicly traded on the Nasdaq sometime this summer, and it could also list on the Toronto exchange after that. Currently, Canada’s Public Sector Pension Investment Board and Loral Space & Communications Inc are the company’s main shareholders.
France and Canada’s export credit agencies, BPI and EDC respectively, are expected to be the main lenders, Goldberg said. Quebec’s provincial government is lending C$400 million ($317 million), and Canada’s federal government has promised C$600 million to be a preferred customer. The company also posted C$246 million in net income in 2020.
Executing the LEO plan is what keeps Goldberg up at night now, he said.
“When we decided to go down this path, the two richest people in the universe weren’t focused on their own LEO constellations.”

Nova Scotia Health’s mental health and addictions program hopes to offer more online support to people across the province after receiving a significant donation this week.
The QEII Foundation announced that RBC is contributing $600,000 toward the province’s e-mental health programming.
“It’s particularly important for the current time under all the strains of COVID,” said Dr. Andrew Harris, a psychiatrist and the senior medical director for the program.
The plan for online programming has been in the works for years, he said, but the pandemic expedited the push. Last June, the department launched a number of applications that can be used to help those with anxiety, depression and addictions.
Since then, as many as 3,000 Nova Scotians have used the site to access mental health services.
“There’s a persistent difficulty in accessing services,” Harris said of traditional models in Nova Scotia. He said those who don’t need intensive therapy may find the support they need through the online programs.
He uses the example of someone who can’t take time off work to speak to a clinician.
“It’s better for them to be able to access a service after hours or on the weekend. So our e-mental health services are tailored a little bit to meet that need.”
Calls to crisis line increase
Harris said the province’s mental health crisis line continues to see a 30 per cent increase in calls for help, so he’s trying to raise awareness that services can be accessed immediately online.
“I think everyone is aware that for a lot of people it’s much easier to talk about a physical illness than a mental illness. So there’s an allowance there for privacy, for some anonymity but still making available things that can help the person who is struggling in the community.”
The online portal has a list of programs that people can use, covering things like reducing stress, solving problems and becoming mindful. It mirrors a site in Newfoundland and Labrador that Harris said is used to help people in remote areas.
Harris said the donation from RBC will be used to continue to evaluate more services, and pay for the licensing of the products that are mostly developed by other organizations.
He encourages anyone who is struggling to test out the site, and use it as an entry point into the mental health system.
“It’s important for people to acknowledge when they’re struggling. It happens to all of us through our lives in different times.”

Samsung
- Release date: April 9
- Price: $499.99
The Galaxy A52 5G is the most expensive smartphone of the bunch. It comes with a 6.5-inch FHD+ screen and a quad-camera system that includes some of the same features as Samsung’s more expensive Galaxy S phones. These include Single Take, which creates several different photos or video clips with different effects with a single press of the shutter button.
Its screen can also boost its refresh rate up to 120Hz for smoother scrolling and performance, a feature that has become common on pricier flagship phones but is rare on cheaper models. It’s also the only phone in this A-series lineup to include Samsung’s notch-free screen design.

- Price: $399.99
The less expensive Galaxy A42 5G has a slightly larger screen than the A52 5G, but scales back on certain features when it comes to the camera and screen refresh rate.
Still, it has a triple-lens camera with high-resolution sensors, and like its pricier sibling it also supports Single Take.
Samsung
Release date: April 9
Price: $279.99
The Galaxy A32 5G is Samsung’s cheapest 5G smartphone to date. It has a large 6.5-inch screen, but it’s made from an LCD panel instead of Super AMOLED. That means it will likely lack some of the contrast and boldness of Samsung’s other devices. But Samsung hasn’t skimped on the camera considering this model has a quad-lens main camera, which is rare if not unheard of at that price.
Samsung
Release date: April 9
Price: $179.99
Samsung’s Galaxy A12 doesn’t come with 5G support, but it still gives you a lot for the price. For less than $200, you’re getting a quad-lens camera and a large 6.5-inch LCD screen. But remember this phone only has 32GB of storage, so it’s best suited for those who don’t store a lot of photos and videos on their device.
Samsung
- Release date: April 29
- Price: $109.99
The Galaxy A02s is Samsung’s cheapest phone, offering a 6.5-inch LCD screen and three main cameras. It doesn’t have 5G support or as much computing power or camera prowess as Samsung’s other A-series phones, but that’s to be expected for a device at this price. This phone is truly for those who just need the basics and little else.
