SpaceX completes Starship static fire test with all six engines

2:30 pm

Capitalism in space: SpaceX today successfully completed a short static fire test of Starship prototype #20 using all six orbital engines.

Though this prototype has previously completed static fire tests, those used only two engines. This test was the first using all the engines that will fly on the spacecraft’s first orbital flight.

When that flight will occur remains uncertain. Elon Musk has said it could fly as early as this month. First however the FAA must give final approval of its environmental reassessment of SpaceX’s Boca Chica spaceport. The agency has released a preliminary draft approval, but that is not yet finalized, with no clear date on when an approval will be issued.

At launch
Falcon 9 lifts off from Cape Canaveral.

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch four astronauts to ISS on its new Endurance capsule.

SpaceX now has three capsules in its manned fleet, Endeavour, Resilience, and Endurance. This was the company’s fifth manned launch, and its fourth for NASA. The crew will dock with ISS tomorrow in the early evening.

The company also successfully landed its first stage, which was also making its second flight.

The leaders in the 2021 launch race:

41 China
24 SpaceX
18 Russia
4 Northrop Grumman
4 ULA
4 Europe (Arianespace)

China now leads the U.S. 41 to 37 in the national rankings.

Viewing tonight’s Endurance launch with four astronauts

9:25 am

NASA has published an updated schedule for the launch tonight of four astronauts to ISS in SpaceX’s new Endurance Dragon capsule.

The launch now is targeted for no earlier than 9:03 p.m. EST Wednesday, Nov. 10, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The launch follows a successful return of the agency’s SpaceX Crew-2 mission.

The Crew Dragon Endurance is scheduled to dock to the space station at 7:10 p.m. Thursday, Nov. 11. Launch and docking coverage will air live on NASA Television, the NASA app, and the agency’s website.

You can also watch it on SpaceX’s website, as well as the embedded live stream below, which begins around 4 pm (Eastern).

This will be the fourth manned flight SpaceX has launched for NASA, the fifth overall using three spacecraft.

New space tug to launch in January ’22

3:45 pm

Capitalism in space: A ew space tug, designed and built by the company Spaceflight, is set to launch in January ’22 on a SpaceX Falcon 9 rocket and deploy 13 satellites in two different orbits.

In a mission Spaceflight dubs SXRS-6, the OTV [orbital transfer vehicle] will first place four microsatellites and five cubesats in Sun Synchronous Orbit (SSO) at 525 kilometers altitude, after being deployed from SpaceX’s Falcon 9 rocket.

About a month later, following various commissioning and system tests, Sherpa-LTC1 will use its bipropellant, green propulsion subsystem from Benchmark Space Systems to maneuver to 500 kilometers, where it will deploy its remaining four cubesats.

This technology gives cubesat owners greater flexibility. Even if they launch as a secondary payload that is not placed in the right orbit, the tug can still get them to their preferred orbit.

NASA admits manned lunar landing can’t happen before ’25

3:37 pm

NASA administrator Bill Nelson admitted today that the goal of landing Americans back on the Moon by 2024 was impossible, and that the agency has now delayed that target date one year to 2025.

Nelson attempted to blame the delay on Blue Origin’s lawsuit against NASA for its award of the manned lunar lander contract to SpaceX.

He blamed the shifting timeline on a lawsuit over the agency’s moon lander, to be built by SpaceX, and delays with NASA’s Orion capsule, which is to fly astronauts to lunar orbit. “We’ve lost nearly seven months in litigation, and that likely has pushed the first human landing likely to no earlier than 2025,” Mr. Nelson said, adding that NASA will need to have more detailed discussions with SpaceX to set a more specific timeline.

This however is a bald-faced lie. The Trump 2024 deadline was never realistic. Moreover, delays in SLS and Orion have been continuous and ongoing for years, all of which made a ’24 landing quite difficult and if attempted extremely unsafe. Even as it is, trying this mission by ’25 is risky, especially if it depends on SLS. Moreover, as the article notes, how SLS, Orion, and SpaceX’s Starship will team up to get this mission — designed by a committee — to and from the Moon remains exceedingly unclear.

With great confidence I predict that if the lunar mission depends on SLS in any manner, it will not launch in ’25 either.

Endeavour safely splashes down in the Gulf of Mexico

8:38 pm

A crew of four astronauts has successfully splashed down in SpaceX’s Endeavour capsule, landing in the Gulf of Mexico.

One of the four chutes appeared to inflate late, though the capsule is designed to land with only three chutes. It eventually inflated prior to landing.

Recovery efforts are now proceeding. It is expected that they will be on board ship in about an hour.

Endeavour undocking from ISS delayed one day; Endurance launch still set for November 10th

9:03 am

Because of high winds, the undocking of Endeavour from ISS was delayed from yesterday until today, with the landing now set for later this evening.

If conditions are favorable Monday, Crew-2 astronauts Shane Kimbrough, Megan McArthur, Akihiko Hoshide and Thomas Pesquet will enter their Crew Dragon capsule currently attached to the International Space Station and depart at 2:05 p.m. ET. Splashdown in one of seven potential landing sites off the Florida coast is expected about eight hours later at 10:33 p.m. ET.

The 24-hour delay from Sunday to Monday, however, didn’t impact the timing for another crew waiting to swap positions. Crew-3 astronauts Kayla Barron, Raja Chari, Thomas Marshburn, and Matthias Maurer are prepping for their Falcon 9 launch currently scheduled for no earlier than 9:03 p.m. Wednesday. Kennedy Space Center’s pad 39A will host.

Both NASA and SpaceX want to get Endeavour back to Earth, as it has already exceeded the six month time it is designed (at present) to stay in space.

Endeavour and crew to return to Earth tomorrow

9:28 am

UPDATE: The landing and launch have been delayed again because of weather, with the ISS crew now targeting a splashdown tomorrow, November 8th, and the new crew targeting a November 10th launch.

The four astronauts who were brought to ISS six months ago by the Dragon capsule Endeavour will now return to Earth early tomorrow, ahead of the next crew that is now scheduled to launch to ISS on November 10th on the Dragon capsule Endurance.

NASA’s SpaceX Crew-2 mission now is targeting a return to Earth no earlier than 7:14 a.m. EST Monday, Nov. 8, with a splashdown off the coast of Florida. The Crew Dragon spacecraft, named Endeavour, is scheduled to undock from the International Space Station at 1:05 p.m. Sunday, Nov. 7, to begin the journey home. NASA will preview the mission on Saturday, Nov. 6 and provide coverage Sunday of the mission on NASA Television, the NASA app, and the agency’s website.

The agency decided to flip the two events in order to make sure it could get Endeavour back to Earth before it exceeded its seventh-month life limit in space.

A reminder: Both the splashdown of Endeavour and the launch of Endurance will be run by a private company, SpaceX, with the government merely acting as customer. Every worker you see, except for the astronauts, will be employees of SpaceX, not NASA.

SpaceX begins filling tanks at Starship orbital launchpad

9:03 am

Capitalism in space: SpaceX has begun the process of filling the many tanks at its Starship orbital launchpad in Boca Chica, requiring more than a hundred truck deliveries of nitrogen (for cleaning the interior of the tanks as well as cooling the propellants) and oxygen.

In mid-September, SpaceX began delivering cryogenic fluids to Starbase’s orbital tank farm for the first time ever. Instead of propellant, dozens of tanker trucks delivered liquid nitrogen to one or two of the farm’s tanks between mid-September and mid-October. Altogether, around 40-60 truckloads was delivered – only enough to partially fill one tank. That liquid nitrogen also appeared to be piped into two of the farm’s three liquid oxygen tanks, meaning that it may have only been used to clean and proof test them.

Combined, the farm’s seven main tanks should be able to store roughly 2400 tons (5.3M lb) of liquid methane (LCH4), 5400 tons (12M lb) of liquid oxygen (LOx), and 2600 tons (5.7M lb) of liquid nitrogen (LN2). LCH4 and LOx are Starship’s propellant, while LN2 is needed to ‘subcool’ that propellant below its boiling point, significantly increasing its density and the mass of propellant Starships can store.

It appears that while SpaceX has begun storing oxygen, it has not yet begun loading its methane tanks. When that fuel begins arriving we will know that an orbital launch of Starship is imminent.

Astra proposes its own 13,000 satellite internet constellation

9:17 pm

Capitalism in space: Astra, the startup smallsat rocket company that has yet to successfully complete an orbital launch, has filed with the FCC a proposal to launch a 13,000 satellite constellation for providing internet services globally.

Astra said its satellites would be built in-house, and would be launched on Astra’s own rockets. The satellites would be sent into orbital altitudes ranging from 236 to 435 miles (380 to 700 kilometers), and would be equipped with propulsion systems to aid in collision avoidance and post-operational deorbiting.

Potential applications for Astra’s high-bandwidth connectivity would include communications services, environmental and natural resource applications and national security missions.

Though Astra could certainly launch many of these satellites itself, it is unlikely it launch them all with its small rocket. Thus, more launch business for other rocket companies!

Weather forces another delay for Endurance launch to ISS

9:05 pm

Because of poor weather expected on November 7 evening NASA and SpaceX have once again delayed the launch of the manned Dragon capsule Endurance carrying four astronauts to ISS.

The U.S. space agency and SpaceX have pushed the launch of the Crew-3 mission, which will send four astronauts to the International Space Station, from Saturday (Nov. 6) to Monday (Nov. 8) at the earliest, because of anticipated bad weather over the coming days.

NASA and SpaceX are also now considering whether to bring the four astronauts of the previous mission, Crew-2, back down to Earth before sending Crew-3 skyward.

The reason they might bring the crew home first is because the capsule they will be using, Endeavour, is only rated to stay in space for seven months, and the end of that time period is approaching. If they wait much longer, the mediocre November weather could prevent a return before that end date is reached.

Court denies Blue Origin’s suit against NASA lunar lander contract award to SpaceX

10:17 am

The U.S. Court of Federal Claims yesterday denied Blue Origin’s suit against NASA’s lunar lander contract award to SpaceX’s Starship spacecraft.

NASA has immediately said it “will resume work with SpaceX under the Option A contract as soon as possible.”

I guess Blue Origin might have to consider the idea of actually building stuff now.

Falcon Heavy gets another contract

9:50 am

Capitalism in space: With the announcement on October 30th that the Space Force has added a third military Falcon Heavy launch for ’22, the rocket is now scheduled to fly five times next year.

The addition of a third national security mission for Falcon Heavy will make for quite a scheduling challenge for SpaceX’s three-core rocket that also is projected to launch in 2022 a Viasat-3 commercial broadband satellite with an Astranis communications satellite as a secondary payload, as well as NASA’s Psyche planetary science mission.

The Space Force missions USSF-44 and USSF-52 both were scheduled to fly in 2021 but have been delayed by payload readiness and range scheduling issues. No target launch dates have been announced yet although the Space Force said they would happen in 2022. Falcon Heavy rockets lift off from NASA’s Kennedy Space Center.

It increasingly looks like 2022 will be a major record-setting year for rocketry.

Dragon manned launch delayed again

3:48 pm

NASA announced today that the manned launch of four astronatus to ISS on SpaceX’s Endurance spacecraft has been delayed again, pushed back to November 6tth because of a “minor medical issue”.

The agency says one of the astronauts has a “minor medical issue.” The issue is not a medical emergency and not related to COVID-19, according to NASA.

The launch is now set for 11:36 pm (Eastern) that evening.

Dragon crew launch to ISS delayed due to weather

10:57 pm

The early morning launch on October 31st of the next manned flight of SpaceX’s Endurance capsule to ISS, has been delayed because of poor weather downrange from the launch site.

The bad weather could have interfered with recovery operations should a launch abort had been necessary and the capsule was forced to land in the Atlantic.

The launch has now been rescheduled for 1:10 am (Eastern) on November 3rd.

Holes in snowy ice on Mars?

1:30 pm

Holes in snowy ice on Mars?
Click for full image.

Cool image time! Today we return to the regions surrounding Milankovic Crater in the high northern latitudes of Mars. The photo to the right, cropped and reduced to post here, was taken on June 1, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a spray of impact craters where the bolides apparently landed in relatively soft material. The location itself is about 10 miles to the southeast of the 74-mile-wide crater, and sits within its rim ejecta blanket.

The label for the image says this is showing “crater modification,” which suggests that the rimless nature of these craters became so after their creation. This location, at 54 north latitude, is in a region of Mars where scientists have found a lot of evidence of near surface ice. For example, within Mikankovic Crater itself they have identified numerous scarps with clearly seen pure ice layers.

If ice is close to the surface here, then the ground could be like soft snow on Earth, especially because Mars’ lighter gravity would not compress that ice as much. Think about what happens when you toss pebbles into soft snow. They fall through, and leave behind holes not unlike the ones we see in this picture. Later, sunlight would begin to modify the holes so that their edges grow outward, once again exactly as we see here.

The overview map below as always gives some context, which in this case has less to do with Mars but with Elon Musk and Starship.

Russians certify Dragon for flying its astronauts

9:02 am

Capitalism in space: The head of Russia’s space agency Roscosmos, said yesterday that they have finally approved the use of SpaceX’s Dragon capsules to launch their astronauts to ISS.

Crew Dragon spaceships of Elon Musk’s SpaceX company have gained substantial experience for Russian cosmonauts to travel aboard them as part of cross flights, Head of Russia’s State Space Corporation Roscosmos Dmitry Rogozin said on Monday. “From our viewpoint, SpaceX has gained sufficient experience for representatives of our crews to make flights aboard its spacecraft,” the Roscosmos chief told reporters at the 72nd international astronautical congress.

Russia will now begin barter negotiations for the future flights, whereby for each Russian that flies on Dragon an American will get a free flight on Soyuz.

Space Adventures fails to find customer for Dragon orbital flight

10:35 pm

Capitalism in space: A high orbital tourist flight on SpaceX’s Dragon capsule has been cancelled because the company organizing it, Space Adventures, apparently failed to find enough customers.

Company spokesperson Stacey Tearne confirmed to SpaceNews that the company had dropped plans for the mission. “The mission was marketed to a large number of our prospective customers, but ultimately the mix of price, timing and experience wasn’t right at that particular time and our contract with SpaceX expired,” she said. “We hope to revisit the offering in the future.”

This revises the list of scheduled of orbital tourist flight that began with SpaceX’s Inspiration4 flight in September.

  • September 15, 2021: SpaceX’s Dragon capsule flew four private citizens on a three day orbital flight
  • October 5-17, 2021: Two Russians fly to ISS for 12 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • January/February 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Why Space Adventures could not get enough customers for their Dragon flight is unclear. It could be for many reasons outside of not enough demand. For example, SpaceX might have determined that the prospective customers were not physically capable for the flight. Maybe Space Adventures sold two or three tickets, but couldn’t fill the manifest before their SpaceX contract expired.

The cancellation however does suggest that the price per ticket might have to come down to garner business for orbital tourist space flights. Or those flights need to arrive at a space station where the passengers can spend more than two or three days.

Musk: Starship orbital flight could happen as soon as next month

2:57 pm

Capitalism in space: Elon Musk today announced that SpaceX will be ready to launch the first orbital flight of Starship as soon as one month from now.

“If all goes well, Starship will be ready for its first orbital launch attempt next month, pending regulatory approval,” Musk tweeted today [emphasis mine]

Musk’s tweet came one day after the FAA completed its public hearings on its environment reassessment of SpaceX’s operations in Boca Chica. Before the agency can approve that reassessment it has to digest the comments, then to hold an “industry workshop” on this reassessment.

Thus, while SpaceX is ready to go, our lumbering, oppressive government is not. As I’ve written before, I fully expect there to be pressure from the Biden administration and NASA to slow walk that government approval so that Starship does not launch before February 2022, when SLS is now scheduled for its first launch. Having SpaceX get its heavy lift rocket into orbit before NASA would be very embarrassing, considering that SpaceX has spent about a third the time and about a tenth the money getting it done.

I hope I am wrong, but this is what I expect from the corrupt federal government we now have.

Senate committee: NASA must choose two companies to build manned lunar lander

5:09 pm

We’re here to help you! Despite offering NASA only $100 million more for the program, the Senate Appropriations committee has directed the agency to award a second manned lunar lander contract, in addition to the one it gave SpaceX in April.

On Tuesday (Oct. 18), the Senate Appropriations Committee — the largest U.S. Senate committee that oversees all discretionary spending legislation in the Senate — released a draft report of nine appropriations bills for the fiscal year 2022 which included funding for NASA, according to SpaceNews.

The appropriators, in the report, state that NASA’s HLS program is not underfunded, despite the agency’s previous claims to the contrary. As shown in the report, the bill includes $24.83 billion for NASA, which is just slightly more than the $24.8 billion that NASA requested, and a $100 million increase in funding for HLS.

“NASA’s rhetoric of blaming Congress and this Committee for the lack of resources needed to support two HLS teams rings hollow,” the report states. The committee added that “having at least two teams providing services using the Gateway should be the end goal of the current development program,” referencing NASA’s Gateway, a planned lunar space station.

It might be possible for the increase in funding to cover a second contract, if that contract was awarded to Blue Origin. Jeff Bezos has made it clear that he would be willing to waive as much as $2 billion of the price for the contract, using his own ample funds to make up the difference. Whether that is enough to build it, with the $100 million the Senate appropriated, is unclear.

This bill of course has to pass the Senate, be approved as written by the House, and then signed by the President. These directives and budget changes thus might not end up in the final appropriations bill.
