For the second time this year, NASA’s JPL center cuts its workforce

12 November 2024 at 21:55

Barely nine months after the last cut, NASA's Jet Propulsion Laboratory will again reduce its workforce. On Wednesday, the lab will lay 325 employees off, representing about 5 percent of the workforce at the California-based laboratory that leads the development of robotic space probes for NASA.

"This is a message I had hoped not to have to write," JPL Director Laurie Leshin said in a memo to staff members on Tuesday morning, local time. "Despite this being incredibly difficult for our community, this number is lower than projected a few months ago thanks in part to the hard work of so many people across JPL."

The cuts this week follow a reduction of 530 employees in February of this year due to various factors, including a pause in funding for the Mars Sample Return mission. The NASA laboratory has now cut about one-eighth of its workforce this year.

Russia: Fine, I guess we should have a Grasshopper rocket project, too

11 November 2024 at 14:42

Like a lot of competitors in the global launch industry, Russia for a long time dismissed the prospects of a reusable first stage for a rocket.

As late as 2016, an official with the Russian agency that develops strategy for the country's main space corporation, Roscosmos, concluded, "The economic feasibility of reusable launch systems is not obvious." In the dismissal of the landing prospects of SpaceX's Falcon 9 rocket, Russian officials were not alone. Throughout the 2010s, competitors including space agencies in Europe and Japan, and US-based United Launch Alliance, all decided to develop expendable rockets.

However, by 2017, when SpaceX re-flew a Falcon 9 rocket for the first time, the writing was on the wall. "This is a very important step, we sincerely congratulate our colleague on this achievement," then-Roscosmos CEO Igor Komarov said at the time. He even spoke of developing reusable components, such as rocket engines capable of multiple firings.

Space policy is about to get pretty wild, y’all

8 November 2024 at 19:49

The global space community awoke to a new reality on Wednesday morning.

The founder of this century's most innovative space company, Elon Musk, successfully used his fortune, time, and energy to help elect Donald Trump to president of the United States. Already, Musk was the dominant Western player in space. SpaceX launches national security satellites and NASA astronauts and operates a megaconstellation. He controls the machines that provide essential space services to NASA and the US military. And now, thanks to his gamble on backing Trump, Musk has strong-armed himself into Trump's inner circle.

Although he may not have a cabinet-appointed position, Musk will have a broad portfolio in the new administration for as long as his relations with Trump remain positive. This gives Musk extraordinary power over a number of areas, including spaceflight. Already this week, he has been soliciting ideas and input from colleagues. The New York Times reported that Musk has advised Trump to hire key employees from SpaceX into his administration, including at the Department of Defense. This reflects the huge conflict of interest that Musk will face when it comes to space policy. His actions could significantly benefit SpaceX, of which he is the majority owner and has the final say in major decisions.

The next Starship launch may occur in less than two weeks

6 November 2024 at 21:01

Less than a month has passed since the historic fifth flight of SpaceX's Starship, during which the company caught the booster with mechanical arms back at the launch pad in Texas. Now, another test flight could come as soon as Nov. 18, the company announced Wednesday.

The improbable but successful recovery of the Starship first stage with "chopsticks" last month, and the on-target splashdown of the Starship upper stage halfway around the world, allowed SpaceX to avoid an anomaly investigation by the Federal Aviation Administration. Thus, the company was able to press ahead on a sixth test flight if it flew a similar profile.

And that's what SpaceX plans to do, albeit with some notable additions to the flight plan.

After 31 cargo missions, NASA finds Dragon still has some new tricks

5 November 2024 at 18:16

A Cargo Dragon spacecraft docked to the International Space Station on Tuesday morning, less than a day after lifting off from Florida.

As space missions go, this one was fairly routine, ferrying about 6,000 pounds (2,700 kg) of cargo and science experiments to the space station. Over the course of nearly a dozen years, this was the 31st cargo supply mission that SpaceX has flown for NASA to the orbiting laboratory.

However, there is one characteristic of this flight that may prove significant for NASA and the future of the space station. As early as Friday, NASA and SpaceX have scheduled a "reboost and attitude control demonstration," during which the Dragon spacecraft will use some of the thrusters at the base of the capsule. This is the first time the Dragon spacecraft will be used to move the space station.

The New Glenn rocket’s first stage is real, and it’s spectacular

30 October 2024 at 14:09

Blue Origin took another significant step toward the launch of its large New Glenn rocket on Tuesday night by rolling the first stage of the vehicle to a launch site at Cape Canaveral, Florida.

Although the company's rocket factory in Florida is only a few miles from Launch Complex 36 at Cape Canaveral Space Force Station, because of the rocket and transporter's size, the procession had to follow a more circuitous route. In a post on LinkedIn, Blue Origin's chief executive, Dave Limp, said the route taken by the rocket to the pad is 23 miles long.

Limp also provided some details on GERT, the company's nickname for the "Giant Enormous Rocket Truck" devised to transport the massive New Glenn first stage.

NASA’s oldest active astronaut is also one of the most curious humans

28 October 2024 at 22:12

For his most recent trip to the International Space Station, in lieu of bringing coffee or some other beverage in his "personal drink bag" allotment for the stay, NASA astronaut Don Pettit asked instead for a couple of bags of unflavored gelatin.

This was not for cooking purposes but rather to perform scientific experiments. How many of us would give up coffee for science?

Well, Donald Roy Pettit is not like most of us.

SpaceX has caught a massive rocket. So what’s next?

28 October 2024 at 12:00

The stupefying and stupendous capture of a Starship rocket earlier this month by two mechanical arms marked a significant step forward in SpaceX’s efforts to forever alter humanity’s relationship with the heavens.

Yet as remarkable as the rocket catch was, it represents but a single step on a long path. SpaceX seeks to make launch cheap, frequent, and reliable with Starship, and the company is working toward a day when rockets are routinely caught by the launch tower, set back on a launch mount, refueled, and flown again within hours. SpaceX says these efforts will one day culminate in Starships landing on the Moon and Mars.

Critics of the Starship architecture say it is inefficient because of the mass refueling that must occur in low-Earth orbit for the spacecraft to travel anywhere. For example, fully topping off a Starship that can land humans on the Moon and return them to lunar orbit may take a dozen or more tanker flights. But this only seems stupidly impractical under the old space paradigm, in which launch is expensive, scarce, and unreliable. Such criticism seems less salient if we imagine SpaceX reaching the point of launching a dozen Starships a week or more in a few years.

Why is Elon Musk talking to Vladimir Putin, and what does it mean for SpaceX?

25 October 2024 at 21:47

In a blockbuster story published Friday morning, The Wall Street Journal reports that Elon Musk has been in regular contact with Russian President Vladimir Putin for about two years, with the discussions covering a range of issues from geopolitics to business to personal matters.

There are no on-the-record sources confirming the regular conversations between Musk and Putin, and Musk did not comment to the news organization. A Putin spokesperson said the Russian leader and Musk have had just one telephone call. However, the report is plausibly true, and the Journal cites "several current and former US, European, and Russian officials." This is also not the first time there have been reports of contact between Musk and Putin.

The new story about Musk's direct links to an avowed enemy of the United States immediately raised concerns among some prominent US officials who work with the billionaire entrepreneur, including NASA Administrator Bill Nelson.

If you thought Astra was going to go away quietly, you were wrong

25 October 2024 at 18:01

On Wednesday morning, a surprising email popped into my inbox with the following subject line: "Astra announces Department of Defense contract valued up to $44 Million."

I had to read it a second time to make sure I got it right. Astra, the launch company? Astra, whose valuation went from $2.6 billion to $25 million after a series of launch failures? Astra, the company that was taken private in July at 50 cents a share?

Yes, it was that Astra.
