There was a straight shot from Earth to the Moon and Mars last night

14 January 2025 at 23:21

I almost missed it. Amid a bout of prime-time doomscrolling, a social media post reminded me there was something worth seeing in the sky. Mars disappeared behind the full Moon for a little more than an hour Monday night, an event visible across most of North America and parts of Africa.

So I grabbed my camera, ran outside, and looked up just as Mars was supposed to emerge from the Moon's curved horizon. Seen with the naked eye, the Moon's brightness far outshined Mars, casting soft shadows on a cold winter evening in East Texas.

Viewing the Moon through binoculars, the red planet appeared just above several large partially shadowed craters at the edge of the Moon's curved limb. I quickly snapped dozens of photos with my handheld Canon 80D fitted with a 600 mm lens. Within a few minutes, Mars rose farther above the Moon's horizon. Thanks to the parallax effect, the Moon's relative motion in its orbit around Earth appears significantly faster than the movement of Mars in its orbit around the Sun.

SpaceX is superb at reusing boosters, but how about building upper stages?

14 January 2025 at 12:20

On any given day, SpaceX is probably launching a Falcon 9 rocket, rolling one out to the launch pad or bringing one back into port. With three active Falcon 9 launch pads and an increasing cadence at the Starbase facility in Texas, SpaceX's teams are often doing all three.

The company achieved another milestone Friday with the 25th successful launch and landing of a single Falcon 9 booster. This rocket, designated B1067, launched a batch of 21 Starlink Internet satellites from Cape Canaveral Space Force Station, Florida.

The rocket's nine kerosene-fueled Merlin 1D engines powered the 21 Starlink satellites into space, then separated from the Falcon 9's upper stage, which accelerated the payload stack into orbit. The 15-story-tall booster returned to a vertical propulsive landing on one of SpaceX's offshore drone ships in the Atlantic Ocean a few hundred miles downrange from Cape Canaveral.

Rocket Report: China launches refueling demo; DoD’s big appetite for hypersonics

10 January 2025 at 19:22

Welcome to Edition 7.26 of the Rocket Report! Let's pause and reflect on how far the rocket business has come in the last 10 years. On this date in 2015, SpaceX made the first attempt to land a Falcon 9 booster on a drone ship positioned in the Atlantic Ocean. Not surprisingly, the rocket crash-landed. In less than a year and a half, though, SpaceX successfully landed reusable Falcon 9 boosters onshore and offshore, and now has done it nearly 400 times. That was remarkable enough, but we're in a new era now. Within a few days, we could see SpaceX catch its second Super Heavy booster and Blue Origin land its first New Glenn rocket on an offshore platform. Extraordinary.

Our annual ranking of the top 10 US launch companies. You can easily guess who made the top of the list: the company that launched Falcon rockets 134 times in 2024 and launched the most powerful and largest rocket ever built on four test flights, each accomplishing more than the last. The combined 138 launches is more than NASA flew the Space Shuttle over three decades. SpaceX will aim to launch even more often in 2025. These missions have far-reaching impacts, supporting Internet coverage for consumers worldwide, launching payloads for NASA and the US military, and testing technology that will take humans back to the Moon and, someday, Mars.

A taller, heavier, smarter version of SpaceX’s Starship is almost ready to fly

9 January 2025 at 21:59

An upsized version of SpaceX's Starship mega-rocket rolled to the launch pad early Thursday in preparation for liftoff on a test flight next week.

The two-mile transfer moved the bullet-shaped spaceship one step closer to launch Monday from SpaceX's Starbase test site in South Texas. The launch window opens at 5 pm EST (4 pm CST; 2200 UTC). This will be the seventh full-scale test flight of SpaceX's Super Heavy booster and Starship spacecraft and the first of 2025.

In the coming days, SpaceX technicians will lift the ship on top of the Super Heavy booster already emplaced on the launch mount. Teams will then complete the final tests and preparations for the countdown on Monday.

NASA defers decision on Mars Sample Return to the Trump administration

8 January 2025 at 18:44

For nearly four years, NASA's Perseverance rover has journeyed across an unexplored patch of land on Marsβ€”once home to an ancient river deltaβ€”and collected a slew of rock samples sealed inside cigar-sized titanium tubes.

These tubes might contain tantalizing clues about past life on Mars, but NASA's ever-changing plans to bring them back to Earth are still unclear.

On Tuesday, NASA officials presented two options for retrieving and returning the samples gathered by the Perseverance rover. One alternative involves a conventional architecture reminiscent of past NASA Mars missions, relying on the "sky crane" landing system demonstrated on the agency's two most recent Mars rovers. The other option would be to outsource the lander to the space industry.

A Cold War mystery: Why did Jimmy Carter save the space shuttle?

30 December 2024 at 13:58

We’d been chatting for the better part of two hours when Chris Kraft’s eyes suddenly brightened. β€œHey,” he said, β€œHere’s a story I’ll bet you never heard.” Kraft, the man who had written flight rules for NASA at the dawn of US spaceflight and supervised the Apollo program, had invited me to his home south of Houston for one of our periodic talks about space policy and space history. As we sat in recliners upstairs, in a den overlooking the Bay Oaks Country Club, Kraft told me about a time the space shuttle almost got canceled.

It was the late 1970s, when Kraft directed the Johnson Space Center, the home of the space shuttle program. At the time, the winged vehicle had progressed deep into a development phase that startedΒ in 1971. Because the program had not received enough money to cover development costs, some aspects of the vehicle (such as its thermal protective tiles) were delayed into future budget cycles. In another budget trick, NASA committed $158 million in fiscal year 1979 funds for work done during the previous fiscal year.

This could not go on, and according to Kraft the situation boiled over during a 1978 meeting in a large conference floor on the 9th floor of Building 1, the Houston center’s headquarters. All the program managers and other center directors gathered there along with NASA’s top leadership. That meeting included Administrator Robert Frosch, a physicist President Carter had appointed a year earlier.

After 60 years of spaceflight patches, here are some of our favorites

29 December 2024 at 12:00

The art of space mission patches is now more than six decades old, dating to the Vostok 6 mission in 1963 that carried Soviet cosmonaut Valentina Tereshkova into low-Earth orbit for nearly three days. The patch for the first female human spaceflight showcased a dove flying above the letters designating the Soviet Union, CCCP.

That patch was not publicly revealed at the time, and the use of specially designed patches was employed only infrequently by subsequent Soviet missions. NASA's first mission patch would not follow for two years, but the practice would prove more sticky for missions in the United States and become a time-honored tradition.

The first NASA flight to produce a mission-specific patch worn by crew members was Gemini 5. It flew in August 1965, carrying astronauts Gordon Cooper and Pete Conrad on an eight-day mission inside a small Gemini spacecraft. At the time, it was the longest spaceflight conducted by anyone.

Rocket Report: ULA has a wild idea; Starliner crew will stay in orbit even longer

20 December 2024 at 19:40

Welcome to Edition 7.24 of the Rocket Report! This is the last Rocket Report of the year, and what a year it's been. So far, there have been 244 rocket launches to successfully reach orbit this year, a record for annual launch activity. And there are still a couple of weeks to go before the calendar turns to 2025. Time is running out for Blue Origin to launch its first heavy-lift New Glenn rocket this year, but if it flies before January 1, it will certainly be one of the top space stories of 2024.

Corkscrew in the sky. A Japanese space startup said its second attempt to launch a rocket carrying small satellites into orbit had been terminated minutes after liftoff Wednesday and destroyed itself again, nine months after the company’s first launch attempt in an explosion, the Associated Press reports. The startup that developed the rocket, named Space One, launched the Kairos rocket from a privately owned coastal spaceport in Japan's Kansai region. Company executive and space engineer Mamoru Endo said an abnormality in the first stage engine nozzle or its control system is likely to have caused an unstable flight of the rocket, which started spiraling in mid-flight and eventually destroyed itself about three minutes after liftoff, using its autonomous safety mechanism.

China orbits first Guowang Internet satellites, with thousands more to come

17 December 2024 at 04:41

The first batch of Internet satellites for China's Guowang megaconstellation launched Monday on the country's heavy-lift Long March 5B rocket.

The satellites are the first of up to 13,000 spacecraft a consortium of Chinese companies plans to build and launch over the next decade. The Guowang fleet will beam low-latency high-speed Internet signals in an architecture similar to SpaceX's Starlink network, although Chinese officials haven't laid out any specifics, such as target markets, service specifications, or user terminals.

The Long March 5B rocket took off from Wenchang Space Launch Site on Hainan Island, China's southernmost province, at 5:00 am EST (10:00 UTC) Monday. Ten liquid-fueled engines powered the rocket off the ground with 2.4 million pounds of thrust, steering the Long March 5B on a course south from Wenchang into a polar orbit.

The US military is now talking openly about going on the attack in space

13 December 2024 at 15:40

ORLANDO, Floridaβ€”Earlier this year, officials at US Space Command released a list of priorities and needs, and among the routine recitation of things like cyber defense, communications, and surveillance was a relatively new term: "integrated space fires."

This is a new phrase in the esoteric terminology the military uses to describe its activities. Essentially, "fires" are offensive or defensive actions against an adversary. The Army defines fires as "the use of weapon systems to create specific lethal and nonlethal effects on a target."

The inclusion of this term in a Space Command planning document was another signal that Pentagon leaders, long hesitant to even mention the possibility of putting offensive weapons in space for fear of stirring up a cosmic arms race, see the taboo of talking about space warfare as a thing of the past.

NASA’s boss-to-be proclaims we’re about to enter an β€œage of experimentation”

12 December 2024 at 14:11

ORLANDO, Floridaβ€”On Wednesday, Jared Isaacman made his first public appearance since his nomination earlier this month to become NASA's next administrator. Although his remarks were short on specifics, Isaacman endorsed a vision that would signal radical departures from the way NASA does business.

He talked of commercial investment, a thriving space economy, and going fast and taking risks. These talking points are familiar to anyone who has listened to NASA's leadership in recent years, and there has been tangible progress in the agency's partnerships with commercial companies. However, NASA is leaving some commercial expertise on the field, or in this case, on the ground.

"I love all about the commercial space industry right now," Isaacman said in a discussion at the Space Force Association's Spacepower Conference in Orlando, Florida. "They’re all generally doing the same thing, which is putting a lot of their own dollars on the line because they believe in the future that it holds."

NASA believes it understands why Ingenuity crashed on Mars

11 December 2024 at 17:44

Eleven months after the Ingenuity helicopter made its final flight on Mars, engineers and scientists at NASA and a private company that helped build the flying vehicle said they have identified what probably caused it to crash on the surface of Mars.

In short, the helicopter's on-board navigation sensors were unable to discern enough features in the relatively smooth surface of Mars to determine its position, so when it touched down, it did so moving horizontally. This caused the vehicle to tumble, snapping off all four of the helicopter's blades.

Delving into the root cause

It is not easy to conduct a forensic analysis like this on Mars, which is typically about 100 million miles from Earth. Ingenuity carried no black box on board, so investigators have had to piece together their findings from limited data and imagery.

In a not-so-subtle signal to regulators, Blue Origin says New Glenn is ready

10 December 2024 at 14:02

Blue Origin said Tuesday that the test payload for the first launch of its new rocket, New Glenn, is ready for liftoff. The company published an image of the "Blue Ring" pathfinder nestled up against one half of the rocket's payload fairing.

"There is a growing demand to quickly move and position equipment and infrastructure in multiple orbits," the company's chief executive, Dave Limp, said on LinkedIn. "Blue Ring has advanced propulsion and communication capabilities for government and commercial customers to handle these maneuvers precisely and efficiently."

This week's announcementβ€”historically Blue Origin has been tight-lipped about new products, but is opening up more as it nears the debut of its flagship New Glenn rocketβ€”appears to serve a couple of purposes.

After critics decry Orion heat shield decision, NASA reviewer says agency is correct

6 December 2024 at 22:29

Within hours of NASA announcing its decision to fly the Artemis II mission aboard an Orion spacecraft with an unmodified heat shield, critics assailed the space agency, saying it had made the wrong decision.

"Expediency won over safety and good materials science and engineering. Sad day for NASA," Ed Pope, an expert in advanced materials and heat shields, wrote on LinkedIn.

There is a lot riding on NASA's decision, as the Artemis II mission involves four astronauts and the space agency's first crewed mission into deep space in more than 50 years.

Two European satellites launch on mission to blot out the Sunβ€”for science

6 December 2024 at 04:39

Two spacecraft developed by the European Space Agency launched on top of an Indian rocket Thursday, kicking off a mission to test novel formation flying technologies and observe a rarely seen slice of the Sun's ethereal corona.

ESA's Proba-3 mission is purely experimental. The satellites are loaded with sophisticated sensors and ranging instruments to allow the two spacecraft to orbit the Earth in lockstep with one another. Proba-3 will attempt to achieve millimeter-scale precision, several orders of magnitude better than the requirements for a spacecraft closing in for docking at the International Space Station.

"In a nutshell, it’s an experiment in space to demonstrate a new concept, a new technology that is technically challenging," said Damien Galano, Proba-3's project manager.

How did the CEO of an online payments firm become the nominee to lead NASA?

5 December 2024 at 19:14

President-elect Donald Trump announced Wednesday his intent to nominate entrepreneur and commercial astronaut Jared Isaacman as the next administrator of NASA.

For those unfamiliar with Isaacman, who at just 16 years old founded a payment processing company in his parents' basement that ultimately became a major player in online payments, it may seem an odd choice. However, those inside the space community welcomed the news, with figures across the political spectrum hailing Isaacman's nomination variously as "terrific," "ideal," and "inspiring."

This statement from Isaac Arthur, president of the National Space Society, is characteristic of the response: "Jared is a remarkable individual and a perfect pick for NASA Administrator. He brings a wealth of experience in entrepreneurial enterprise as well as unique knowledge in working with both NASA and SpaceX, a perfect combination as we enter a new era of increased cooperation between NASA and commercial spaceflight."

Over the weekend, China debuted a new rocket on the nation’s path to the Moon

2 December 2024 at 19:13

China's new Long March 12 rocket made a successful inaugural flight Saturday, placing two experimental satellites into orbit and testing uprated, higher-thrust engines that will allow a larger Chinese launcher in development to send astronauts to the Moon.

The 203-foot-tall (62-meter) Long March 12 rocket lifted off at 9:25 am EST (14:25 UTC) Saturday from the Wenchang commercial launch site on Hainan Island, China's southernmost province. This was also the first rocket launch from a new commercial spaceport at Wenchang, consisting of two launch sites a short distance from a pair of existing launch pads used by heavier rockets primarily geared for government missions.

The two-stage rocket delivered two technology demonstration satellites into a near-circular 50-degree-inclination orbit with an average altitude of nearly 650 miles (about 1,040 kilometers), according to US military tracking data.
