SpaceX successfully completes 10th launch in ’22

9:25 am

Capitalism in space: SpaceX this morning successfully placed 48 Starlink satellites into orbit, using its Falcon 9 rocket.

The first stage landed successfully, completing its fourth flight. The fairings were new.

SpaceX continues to maintain a one-launch-per-week pace in ’22, suggesting it will succeed in completing more than 50 launches this year, as predicted by the company.

The leaders in the 2022 launch race:

10 SpaceX
5 China
2 ULA
2 Russia

The U.S. now leads China 15 to 5 in the national rankings. Note that Russia had predicted it would complete about 27 launches in ’22. With the loss of all of its international customers due to its invasion of the Ukraine, that number is likely cut by two-thirds. If Russia completes more than a dozen launches this year we should be surprised.

NASA buys three more manned Dragon flights from SpaceX

10:10 am

Capitalism in space: NASA today officially announced that it has extended its contract with SpaceX for manned Dragon flights by three, paying the company an additional $900 million.

Prior to the modification, SpaceX was contracted to fly three more missions to the ISS: Crew-4 and Crew-5 in 2022 and Crew-6 in 2023. With the extension, which is “fixed-price, indefinite-delivery/indefinite-quantity,” per NASA’s statement. SpaceX’s period of performance now runs through March 31, 2028 — a nice regular paycheck for the growing launch and space operations company.

This contract extension raises what NASA is paying SpaceX for manned launch services from $2.6 billion to $3.49 billion.

While it is likely NASA would have brought more Dragon flights, it is also likely that some of these flights would have instead been bought from Boeing, if its much delayed Starliner manned capsule had been available. It is not, so SpaceX gets the business.

Boeing’s next attempt to complete Starliner’s first unmanned demo mission to ISS is now scheduled for May.

Northrop Grumman to launch new satellite serving mission in ’24 on Falcon 9

9:12 am

Capitalism in space: Northrop Grumman yesterday announced that it has awarded the contract for the first launch of its Mission Robotic Vehicle (MRV) — designed as a robot capable of installing multiple mission extension pods (MEP) on satellites — to SpaceX for a launch scheduled in 2024.

Once in orbit each MEP [Mission Extension Pod] is captured by the MRV and stowed for transport to the client satellite. The MRV rendezvous and docks with the client to install the MEP, which operates like an auxiliary propulsion device and uses its own thrusters to maneuver the client vehicle. Then the MRV detaches itself and moves on to grab another MEP for the next customer. The MRV is designed to stay in orbit for 10 years.

Anderson said the company expects to install as many as 30 propulsion pods over the life of the MRV.

“Our manifest for the MRV is full through mid 2026,” he said. Besides Optus, five other customers have signed term sheets to purchase mission extension pods.

Essentially, Northrop Grumman upgraded its Mission Extension Vehicle design to separate the repair section from the robot that installs it so that it is cheaper to launch everything. It can now launch multiple lighter and smaller repair pods as needed, with the robot already in orbit ready to go.

SpaceX and Jared Isaacman announce another private Dragon flight

7:24 pm

Capitalism in space: SpaceX and Jared Isaacman, the man who organized and commanded the Inspiration4 private commercial manned Dragon flight last fall, today announced a second private commercial Dragon flight, scheduled for this coming fall.

SpaceX plans to launch a new private astronaut mission, Polaris Dawn, from Florida as early as Nov. 1 and will attempt to conduct the first private spacewalk in history, the company announced Monday.

Businessman Jared Isaacman, founder and CEO of the payments company Shift4, will command the mission, having previously he led the first all-private orbital mission in September known as Inspiration4. Isaacman is an experienced jet pilot.

The crew will also include two SpaceX engineers, Sarah Gillis and Anna Menon, as mission specialists and Isaacman’s business associate, Scott “Kidd” Poteet, as pilot.

The flight will attempt to achieve a higher orbit than even the highest flights during the U.S. space program’s Gemini missions that flew 853 miles above the Earth with astronauts Pete Conrad and Richard Gordon.

Isaacman has also tied this flight to more fundraising for St. Jude’s Children’s Research Hospital in Memphis, suggesting that he was very happy with the charity received in connection with his Inspiration4 spaceflight. If this new flight comes off as planned, Isaacman will follow it up with two more SpaceX manned flights.

For the spacewalk, SpaceX will have to complete the development of its own EVA spacesuit, and have four suits available for the crew since Dragon capsules do not have an airlock.

Rocket stage to hit Moon is from Chinese rocket, not Falcon 9 upper stage

6:22 pm

Astronomers have now concluded that the rocket stage that will impact the Moon on March 4th is not an abandoned the Falcon 9 upper stage that launched the DISCOVR satellite in 2015, but an upper stage from a Chinese rocket.

It was an engineer at NASA’s Jet Propulsion Laboratory, Jon Giorgini, who realized this object was not in fact the upper stage of a Falcon 9 rocket. He wrote to Gray on Saturday morning explaining that the DSCOVR spacecraft’s trajectory did not go particularly close to the Moon, and that it would therefore be a little strange if the second stage strayed close enough to strike it. This prompted Gray to dig back into his data, and identify other potential candidates.

He soon found one—the Chinese Chang’e 5-T1 mission launched in October 2014 on a Long March 3C rocket. This lunar mission sent a small spacecraft to the Moon as a precursor test for an eventual lunar sample return mission. The launch time and lunar trajectory are almost an exact match for the orbit of the object that will hit the Moon in March.

Regardless, it will be very useful to pindown the exact impact time and place so that astronomers can observe it.

Space tug company picks Falcon 9 for test flights

9:39 am

Capitalism in space: Launcher, one of several space tug startups, has awarded SpaceX the contract to launch its first four test flights of its Orbiter tug.

Launcher announced Feb. 7 it signed a multi-launch contract with SpaceX for three additional missions of its Orbiter tug. Those tugs will fly on Falcon 9 rideshare missions in January, April and October of 2023.

Launcher’s first Orbiter tug will launch on SpaceX’s Transporter-6 rideshare mission in October 2022 under a contract announced last June when the company revealed its plans to develop Orbiter. The vehicle is designed to deploy cubesats and other smallsats in their desired orbits as well as host payloads for missions lasting up to two years.

Launcher — along with Momentus, Spaceflight, Astroscale, and several others — are all rushing to build and launch the first tugs for transporting satellites from orbit to orbit, or to remove space junk. Launcher’s deal with SpaceX suggests it is tailoring its system for satellites launched from the Falcon 9.

NASA and SpaceX investigating parachute issue from recent Dragon missions

9:41 am

Both NASA and SpaceX are now conducting an investigation into the delayed release of one of four parachutes during landing on two different Dragon missions recently.

The first incident occurred during the landing of the Dragon capsule Resilience carrying the Inspiration4 commercial crew in November. The second occurred on January 24, 2022 during the return of a cargo freighter.

In both cases there was no safety risk, as the capsules can land safely with only three chutes. However, both NASA and SpaceX want to know why this is happening, and work out a solution to prevent it in the future.

ISS government partners give okay to Axiom’s first commercial crew to station

9:26 am

Capitalism in space: NASA announced yesterday that it as well as the other international partners for ISS have approved the crew and passengers who will fly on Axiom’s first commercial flight to the station, presently scheduled for launch on March 30, 2022, flying in SpaceX’s Endeavour capsule.

Axiom Space astronauts Michael López-Alegría, Larry Connor, Mark Pathy, and Eytan Stibbe are prime crew members of the Ax-1 mission. López-Alegría, who was born in Spain, raised in California, and a former NASA astronaut, will serve as the mission commander. Connor, of Dayton, Ohio, will serve as pilot. Pathy, from Canada, and Stibbe, from Israel, will be mission specialists. The quartet is scheduled to spend eight days aboard the orbiting laboratory conducting science, education, and commercial activities before their return to Earth.

Because the four will be staying at this government station, they must work with NASA, which appears to be requiring them to do some research while on board. Those experiments are still “under review” though Axiom has already revealed a suite of microgravity experiments the crew will perform.

SpaceX launches spy satellite using new first stage

1:37 pm

Capitalism in space: SpaceX today successfully launched from Vandenberg Space Force Base a National Reconnaissance Office spy satellite .

What made this launch unusual was that it used a new first stage, only the third time SpaceX has done so since the beginning of 2020. Last year, of 31 launches all but two used a used first stage. This new first stage landed successfully at Vandenberg.

Coast Guard investigating cruise ship that violated SpaceX launch zone

8:36 am

The Coast Guard has started an investigation of the Royal Caribbean cruise ship, Harmony of the Seas, that violated the launch zone of the SpaceX Falcon 9 launch on January 30, forcing a scrub.

The ship veered into the exclusion zone along a Falcon 9 rocket’s flightpath just before the 6:11 p.m. EST launch, forcing SpaceX to stand down from the mission and prepare for a 24-hour turnaround. Harmony of the Seas is the world’s third-largest cruise ship at 226,963 gross tons. It has 2,747 staterooms, a passenger capacity of 6,687 and a crew of 2,200.

In a statement issued Monday, U.S. Coast Guard spokesperson David Micallef said: “We can confirm the cruise ship was Harmony of the Seas. The Coast Guard is actively investigating Sunday’s cruise ship incursion and postponement of the SpaceX launch.”

“Our primary concern is the safety of mariners at sea, and we will continue to work with our federal, state and local port partners to ensure safe and navigable waterways,” Micallef added.

I am quite certain such investigations are routine, since ship captains are supposed to know about such launches and avoid the launch range accordingly. We normally never hear about them because the violations are almost always done by small boats or planes, not giant cruise ships.

SpaceX’s expected increased launch pace in ’22, combined with the desperate need of the cruise lines to resume normal operations following the Wuhan panic, will probably make this kind of conflict more possible. It also highlights SpaceX’s request to rethink the size of the exclusion zone, since today’s rockets are much more reliable than the rockets of the 1960s, when the zones were first created.

SpaceX successfully launches Italian civilian/military radar satellite

4:22 pm

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to launch an Italian civilian/military radar satellite.

This was the fifth attempt to launch in five days, with the first three attempts canceled due to weather and fourth canceled because a cruise ship had violated the no-go zone in the Atlantic.

The first stage completed its third flight, landing at Cape Canaveral after sunset. I highlight this last fact because it shows how completely routine these 1st stage landing have become. No one even notices that the first stage has come back to Florida, and did in the dark. Also, this 1st stage had originally been configured for Falcon Heavy as one of its side boosters. This was its first flight after being reconfigured.

As I write this the satellite and upper stage are still linked together, coasting to the orbital point where the upper stage can boost the satellite into a transfer orbit and then deploy it. UPDATE: Satellite has successfully deployed.

SpaceX aiming to launch 52 times in 2022

9:31 am

According to NASA officials, SpaceX is hoping to complete as many as 52 launches in 2022, a pace of one launch per week.

The impressive figure was given during a virtual meeting of NASA’s Aerospace Safety Advisory Panel, or ASAP, which gives guidance to the space agency on how to maintain safety within its biggest programs. “NASA and SpaceX will have to be watchful during 2022 that they’re not victims of their success,” Sandy Magnus, a former NASA astronaut and member of the panel, said during the meeting. “There’s an ambitious 52-launch manifest for SpaceX over the course of the year. And that’s an incredible pace.”

Based on other sources, I had previously estimated a SpaceX manifest for ’22 to be 40 launches. That this new higher number comes from NASA’s corrupt safety panel, and was touted as a reason to raise questions about SpaceX, makes me suspicious of it.

Still, a launch pace by SpaceX of one launch per week is wholly possible. For one thing, the company needs to get a lot of Starlink satellites into orbit as quickly as possible. With its development of Starship blocked by government interference, it might have decided to up the pace of launches using Falcon 9.

Furthermore, because most of the rocket is reused, SpaceX has a far greater launch capacity. For every Falcon 9 it builds it gets ten or more launches from its first stage. This means SpaceX does not have to build as much to maintain a high launch pace.

As for the safety panel’s fears about such a pace, who cares? That safety panel has been consistently wrong about everything it has said about SpaceX and commercial space now for almost a decade. It is very likely wrong now. In a more rational world, NASA would have shut it down two years ago for doing such a bad job. Sadly, we no longer live in a rational world.

Falcon 9 upper stage to impact Moon

9:18 am

A Falcon 9 upper stage launched in February 2015 is apparently now on a course to impact the Moon this coming March.

According to Bill Gray, who writes the widely used Project Pluto software to track near-Earth objects, asteroids, minor planets, and comets, such an impact could come in March.

Earlier this month, Gray put out a call for amateur and professional astronomers to make additional observations of the stage, which appears to be tumbling through space. With this new data, Gray now believes that the Falcon 9’s upper stage will very likely impact the far side of the Moon, near the equator, on March 4.

Grey’s call out for more measurements is because there are uncertainties about this prediction. To prepare for observations of the impact by a variety of lunar orbiters, researchers need better data.

SpaceX launches 105 satellites on its third smallsat launch

9:14 am

Capitalism in space: SpaceX today successfully placed 105 satellites and other spacecraft into orbit using its Falcon 9 rocket.

The first stage successfully landed at Cape Canaveral, completing its 10th flight. The launch itself was SpaceX’s third launch dedicated to smallsats in its effort to compete against the small rockets of Rocket Lab, Virgin Orbit, and Astra for that the smallsat market.

Of those 105 satellites, I actually know the owners of two. First, Joe Latrell, frequent commenter here on BtB, put his first Pocketqube cubesat into orbit, testing a variety of space sensors that could be used to track global water use. Second, Jeremiah Pate’s first Lunarsonde prototype cubesat was launched. If successful, he hopes to launch a constellation of similar cubesats for detecting Earth mineral resources, with six more launches already scheduled in ’22 with SpaceX, Virgin Orbit, Rocket Lab, Northrop Grumman, and Arianespace.

This was SpaceX’s second launch in ’22. At the moment the company is the only entity worldwide to launch anything this year, though Virgin Orbit is targeting its own launch later today.

SpaceX launches cargo Dragon to ISS using new 1st stage

9:39 am

Capitalism in space: In what will likely be its last launch in 2021, SpaceX early this morning successfully launched a reused Dragon cargo capsule to ISS.

This was the company’s 31st launch in 2021, extending its record for the most launches in a single year by a private company. The launch’s big news however was that the company used a new first stage booster, only the second time in 2021 that it needed to do so (the first was in May). The first stage successfully landed on the drone ship in the Atlantic, completing SpaceX’s 100th successful recovery.

The first such vertical landing had occurred in December 2015, and now six years later and after a hundred vertical landings, SpaceX remains the only orbital rocket entity in the world with such a capability. A very small handful of companies have performed tests with smaller scale prototypes, but that so much time has passed and no one has pushed forward to meet SpaceX’s challenge with even some full scale preliminary test flights does not reflect well on the innovative culture of the world’s rocket industry.

As for SpaceX’s yearly record, 31 launches actually exceeds the number of launches the entire U.S. rocket industry generally managed each year from 1970 through 2017. During much of that time the launch industry was run by NASA in a Soviet-style top-down system that stifled competition and innovation. Beginning in 2008, when SpaceX won its first contract with NASA, that system was abandoned by NASA, switching instead to capitalism and competition, whereby NASA was merely a customer buying its launches from the open market. The positive results from that change have been breath-taking, proving once again that freedom, competition, and private enterprise will win every single time over government programs and communist/socialist ideology.

The leaders in the 2021 launch race:

48 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

The U.S. and China are now tied 48 to 48 in the national rankings. This was the 127th launch in 2021, tying it with 1976 for the second most successful year in rocketry in the history of space exploration. With five more announced launches on the schedule, there is a chance that this year could tie the record year, 132 in 1975.

SpaceX completes 2nd launch in less than 16 hours

9:33 pm

Capitalism in space: SpaceX tonight successfully completed its second Falcon 9 launch in less than 16 hours (the company’s shortest time between launches), putting the communications satellite Turksat-5B into orbit.

The first stage successfully landed on the drone ship, completing its third flight. Both fairings flew their second flight.

More important, this was the 30th successful launch for SpaceX in 2021, which not only continues to extend its record for the most launches ever in a single year by a private company, it also exceeds the company’s prediction of 29 launches for ’21.

The leaders in the 2021 launch race:

48 China
30 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA

SpaceX in launch of 52 Starlink satellites reuses a 1st stage for the 11th time

9:27 am

Capitalism in space: SpaceX early this morning successfully launched another 52 Starlink satellites into orbit, reusing a Falcon 9 first stage for a record-setting 11th time.

The booster landed successfully on a drone ship in the Pacific, and can now be used again. This success adds weight to the company’s claim a few years ago that the final iteration of the Falcon 9 first stages have the potential for as many as 100 launches. SpaceX has now proven that the stage can fly more than ten times, and still be reused.

This launch also extended SpaceX’s record for the most launches ever by a private company in a single year.

The leaders in the 2021 launch race:

48 China
29 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

China now leads the U.S. 48 to 46 in the national rankings. However, the race to see which country will end up with the most launches is getting tighter. SpaceX has another two launches scheduled in the next three days, with a Virgin Orbit launch following the next day.

This launch was the 125th in 2021, making it the sixth most active year in rocketry since Sputnik. Should those four launches above all succeed, it will be the second most active year, with an outside chance of beating the record of 132 launches from 1975.

SpaceX proposes new launchpads for Starship at Kennedy

10:12 am

Long term Land Use map for Kennedy Space Center
From NASA’s long term road map for Kennedy,

Capitalism in space: SpaceX has submitted a new proposal for building several launchpads at the Kennedy Space Center for its Starship heavy lift rocket, including rebuilding one old pad (LC-39A) and building another at a new site (the never used LC-49).

The project for LC-49 comes in addition to the previously announced work that SpaceX began within the perimeter of Launch Complex 39A, the K Environmental Program Office said. In September 2019, an environmental assessment was completed and a finding of “no significant impact” was issued.

Musk confirmed via Twitter on Dec. 3 that construction of SpaceX’s Starship orbital launch pad at LC-39A was underway. “Construction of Starship orbital launch pad at the Cape has begun”.

The KEP [Kennedy Environmental Program] office noted that this new proposed expansion would allow for not only redundancy with launches of Starship, but also “allow SpaceX to increase the flight rate of Starship and minimize potential disruptions to Falcon, Falcon Heavy and Dragon missions at LC-39A.”

LC-49 is a 175 acre area just north of LC-39B, the launchpad NASA plans to use for its SLS rocket.

It also appears that SpaceX plans on creating a new Starship orbital launchpad at LC-39A that will not impact the use of that site by Falcon 9 and Falcon Heavy, though in the long run launches of those latter rockets will decrease as Starship becomes operational.

All these plans will need a full environmental assessment, but according to the article at the link, the process will be different than at Boca Chica in Texas.

The [environmental assessment]process likely won’t involve live discussions with the public, according to [Don Dankert, the technical lead for the Kennedy Environmental Planning Office], but the public will get comparable information, like with an EIS [Environmental Impact Statement]. “We will put out the same information,” Dankert said. “We’ll put out an informational packet with a .PDF chart, a description of the project and instructions on how to provide comments back to us and SpaceX.”

Engler said there may also be some lessons learned from the process of getting the launch facilities at Starbase approved for an orbital launch, but how that crossover would work has yet to be determined.

Sounds to me that this is all a pointless paperwork dance. The construction will be approved, no matter what, because Florida and Cape Canaveral desperately wants this new business and the jobs and tax dollars it will bring to the state.

SpaceX begins construction of Starship launchpad in Florida

9:48 am

Capitalism in space: Elon Musk yesterday announced that SpaceX has begun the construction of a Starship launchpad at its facility at Cape Canaveral, though no launch scheduled was revealed.

Musk implied that the Starship orbital launchpad is being built at Launch complex 39A. If so, it will pose some scheduling issues for SpaceX, as the company also uses that site for Falcon 9 and Falcon Heavy launches. In fact, it is the only one it uses for Falcon Heavy.

NASA buys more Dragon manned flights

9:41 am

Capitalism in space: To give it some coverage because of continuing delays in Boeing’s Starliner manned capsule, NASA announced yesterday that it has awarded SpaceX contracts for three more manned Dragon manned flights to ISS.

NASA issued a contract notification announcing its plans to issue a sole-source award to SpaceX for three missions. Those missions would be in addition to the six “post-certification missions,” or PCMs, that SpaceX won as part of its $2.6 billion Commercial Crew Transportation Capability (CCtCap) contract in 2014. The announcement did not state the price of those three new missions.

This is money that would have gone to Boeing, if it had gotten its act together and gotten Starliner flying on schedule. Instead, SpaceX is making the profits.

There has been no updates from Boeing since October on the valve issue that now stalls Starliner. While Boeing claims it is aiming for an unmanned demo flight to ISS in early ’22, this remains entirely speculative at this moment.

SpaceX successfully launches NASA asteroid mission

8:58 am

Last night SpaceX’s Falcon 9 rocket successfully launched NASA’s DART asteroid mission.

The first stage landed successfully, completing its third flight. This was SpaceX’s 26th launch in 2021, setting a new record for the company and in fact for any private company ever.

DART’s mission is to test one method for changing an asteroid’s orbit.

After launch tonight, DART will take aim on an asteroid called Dimorphos. The spacecraft will strike Dimorphos at nearly 15,000 mph (about 6.6 kilometers per second).

The primary science goal of the mission is to measure how the high-speed collision next September, which will destroy the DART spacecraft, disrupts the orbit of Dimorphos around nearby Didymos. The data could help plan a future mission to deflect an asteroid on a course to hit Earth.

Dimorphos and its larger companion Didymos pose no near-term threat to Earth, but the asteroids will be close enough to our planet next year for astronomers to observe DART’s impact using ground-based telescopes. The asteroids orbit the sun in an elongated path that occasionally bring them into Earth’s neighborhood. That makes them potentially hazardous asteroids, although scientists say there is no near-term threat from the pair.

No space mission has ever explored Didymos and Dimorphos, but scientists who have observed them through telescopes say the asteroids are about a half-mile (780 meters) and 525 feet (160 meters) in diameter, respectively.

An Italian cubesat is also on board, and will separate from DART about ten days before impact so that it can observe the impact with two camera.

The leaders in 2021 launch race:

43 China
26 SpaceX
18 Russia
5 Europe (Arianespace)

China now leads the U.S. 43 to 41 in the national rankings. For the U.S. SpaceX’s launch last night topped the U.S. total from last year, which was this country’s highest launch total since the 1960s.

Axiom sets launch date for first private commercial manned mission to ISS

8:17 am

Capitalism in space: Axiom has set February 21, 2022 as the target launch date for its first private commercial manned mission to ISS, carrying one employee and three passengers for eight days.

In making the announcement the company emphasized the science research the passengers — Larry Connor, Mark Pathy, and Eytan Stibbe — will do:

The crew activities of Axiom Mission 1 (Ax-1) will focus on science, education, and outreach, conducting approximately 25 experiments while onboard the ISS. Critical data from studies in human research, life and physical sciences, technology demonstrations, and Earth observation will expand the applicability of microgravity research to new sectors. The crew has submitted over 100 hours of human-tended research to conduct during their stay on station.

The commander will be former NASA astronaut Michael López-Alegría, who now works for Axiom. This will be his fifth spaceflight.
