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

30 October 2024 at 13:09

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 21:12

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 11:00

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 19:47

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 16:01

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 JulyΒ at 50 cents a share?

Yes, it was that Astra.

To the astonishment of forecasters, a tiny hurricane just sprang up near Cuba

20 October 2024 at 14:30

A hurricane so small that it could not be observed by satellite formed this weekend, surprising meteorologists and even forecasters at the National Hurricane Center.

Hurricane Oscar developed on Saturday near Turks and Caicos, and to the northeast of Cuba, in the extreme southwestern Atlantic Ocean. As of Saturday evening, hurricane-force winds extended just 5 miles (8 km) from the center of the storm.

This is not the smallest tropical cycloneβ€”as defined by sustained winds greater than 39 mph, or 63 kphβ€”as that record remains held by Tropical Storm Marco back in 2008. However, this may possibly be the smallest hurricane in terms of the extent of its hurricane-force winds.

Rocket Report: Bloomberg calls for SLS cancellation; SpaceX hits century mark

18 October 2024 at 11:00

Welcome to Edition 7.16 of the Rocket Report! Even several days later, it remains difficult to process the significance of what SpaceX achieved in South Texas last Sunday. The moment of seeing a rocket fall out of the sky and be captured by two arms felt historic to me, as historic as the company's first drone ship landing in April 2016. What a time to be alive.

Surprise! Rocket Lab adds a last-minute mission. After signing a launch contract less than two months ago, Rocket Lab says it will launch a customer as early as Saturday from New Zealand on board its Electron launch vehicle. Rocket Lab added that the customer for the expedited mission, to be named "Changes In Latitudes, Changes In Attitudes," is confidential. This is an impressive turnaround in launch times and will allow Rocket Lab to burnish its credentials for the US Space Force, which has prioritized "responsive" launch in recent years.

It’s increasingly unlikely that humans will fly around the Moon next year

17 October 2024 at 19:24

Don't book your tickets for the launch of NASA's Artemis II mission next year just yet.

We have had reason to doubt the official September 2025 launch date for the mission, the first crewed flight into deep space in more than five decades, for a while now. This is principally because NASA is continuing to mull the implications of damage to the Orion spacecraft's heat shield from the Artemis I mission nearly two years ago.

However, it turns out that there are now other problems with holding to this date as well.

We’re finally going to the Solar System’s most intriguing but unexplored frontier

9 October 2024 at 11:30

I really hate to be the bearer of such bad news, but you and I will not live forever, dear reader.

We may hope to draw breath for a few decades yet, perhaps. But that's not long enough to descry any worlds circling other stars in a meaningful way. Those mysterious orbs are too distant, both in space and time; the vastness of this galaxy is too great, the beat of a human life too short against the slow rhythm of cosmic time. We space enjoyers must therefore be content with what lies in our backyard.

If you are of a certain age, say half a century old or less, you may feel as though you missed the golden age of space exploration, when humanity first walked into that backyard. The Baby Boomers, who were born in time to not only see what the lunar surface looked like but to watch humans walk upon it in real time, were truly lucky.

Hurricane Milton becomes second-fastest storm to reach Category 5 status

7 October 2024 at 17:28

In less than a day, Hurricane Milton has rapidly intensified over the southern Gulf of Mexico, exploding from a small Category 1 hurricane into a Category 5 storm. Unfortunately, the hurricane is likely to strengthen further as it tracks eastward toward Florida.

The National Hurricane Center reported that Milton had reached sustained winds of 160 mph as of 11:44 pm ET on Monday, with a central pressure of 925 millibars. The storm is moving steadily eastward and is likely to reach the west coast of Florida on Wednesday evening as a major hurricane.

Based upon Atlantic basin records, Milton has tied Hurricane Maria (2017) for the second-fastest intensification from a Category 1 to Category 5 hurricane, taking just 18 hours. Only Hurricane Wilma (2005) did so more rapidly, in just 12 hours.

We’re only beginning to understand the historic nature of Helene’s flooding

30 September 2024 at 15:25

As of Monday morning, if one wanted to grasp the historic nature of flooding from the remnants of Hurricane Helene in western parts of North Carolina and the surrounding areas, the logical place to begin is at the National Climatic Data Center.

This federal office maintains the world's largest climate data archive and provides historical perspective to put present-day weather conditions and natural disasters into context in a warming world due to climate change.

Unfortunately, the National Climatic Data Center is based in Asheville, North Carolina. As I write this, the center's website remains offline. That's because Asheville, a city in North Carolina's Blue Ridge Mountains, is the epicenter of catastrophic flooding from Hurricane Helene that has played out over the last week. The climate data facility is inoperable because water and electricity services in the region have entirely broken down due to flooding.

NASA is working on a plan to replace its space station, but time is running out

3 October 2024 at 13:37

The next year is crucial for the future of NASA and its plans to extend human activity in low-Earth orbit. For the first time in decades, the US space agency faces the not-too-distant prospect of failing to have at least one crew member spinning around the planet.

Over the next several months, NASA will finalize a strategy for its operations in low-Earth orbit after 2030. Then, toward the end of next year, the space agency will award contracts to one or more private companies to develop small space stations for which NASA and other space agencies will become customers rather than operators.

But none of this is certain, and as NASA faces a transition from its long-established operations on the International Space Station to something new, there are many questions. Foremost among these is whether NASA really needs to continue having a presence on low-Earth orbit at all, especially as the space agency's focus turns toward the Moon with its Artemis Program.

NASA confirms space station cracking a β€œhighest” risk and consequence problem

27 September 2024 at 14:49

US space officials do not like to talk about the perils of flying astronauts on the aging International Space Station, elements of which are now more than a quarter of a century old.

However, a new report confirms that NASA managers responsible for operating the space station are seriously concerned about a small Russian part of the station, essentially a tunnel that connects a larger module to a docking port, which is leaking.

Russian and US officials have known that this small PrK module, which lies between a Progress spacecraft airlock and the Zvezda module, has been leaking since September 2019. A new report, published Thursday by NASA's inspector general, provides details not previously released by the space agency that underline the severity of the problem.

Twenty days after it rolled out to Blue Origin's launch site in Florida, the second stage of the massive New Glenn rocket underwent a successful hot-fire test on Monday.

The second stageβ€”known as GS2 for Glenn stage 2β€”ignited for 15 seconds as part of the "risk reduction" hot-fire test, the company said. The two BE-3U engines, fueled by liquid oxygen and hydrogen and each producing 173,000 pounds of thrust, burned with a nearly transparent flame that approached a temperature of 6,000Β° Fahrenheit.

This marked the first time that Blue Origin, a space company founded by Jeff Bezos more than two decades ago, has integrated and fired an orbital rocket stage. After the test, Blue Origin said it is still tracking toward a November launch of the New Glenn rocket.

A Chinese space startup conducted what it called a "high-altitude" test flight of its Nebula-1 rocket on Sunday, launching the vehicle to an altitude of about 5 km or so before attempting to land it back at the Ejin Banner Spaceport in Inner Mongolia.

The test flight went well for about two and a half minutes before the vehicle experienced a problem just before landing and erupted into a fireball.

This is not the first vertical rocket landing test by a Chinese company, but what sets Deep Blue Aerospace apart from its competitors is its transparency. Within hours the company released a detailed statement about the test flight, its objectives, and a preliminary review of what went wrong.

One company appears to be thriving as part of NASA’s return to the Moon

One of the miracles of the Apollo Moon landings is that they were televised, live, for all the world to see. This transparency diffused doubts about whether the lunar landings really happened and were watched by billions of people.

However, as remarkable a technical achievement as it was to broadcast from the Moon in 1969, the video was grainy and black and white. As NASA contemplates a return to the Moon as part of the Artemis program, it wants much higher resolution video and communications with its astronauts on the lunar surface.

To that end, NASA announced this week that it had awarded a contract to Houston-based Intuitive Machines for "lunar relay services." Essentially this means Intuitive Machines will be responsible for building a small constellation of satellites around the Moon that will beam data back to Earth from the lunar surface.
