SpaceX’s Falcon Heavy completes second launch in 2023

9:08 pm

SpaceX today successfully placed a Viasat communications satellite into geosynchronous orbit using its Falcon Heavy rocket, completing its second launch in 2023. Also on board were two smallsats.

The company did not recover either side booster or the core stage in order to give the rocket the maximum lift to put Viasat’s satellite into its proper orbit. With this flight, the two side boosters had successfully completed eight and three missions during their lifespan.

The leaders in the 2023 launch race:

28 SpaceX
16 China
6 Russia
3 Rocket Lab
3 India

American private enterprise now leads China 31 to 16 in the national rankings, and the entire world combined 31 to 28. SpaceX by itself trails the entire world, including American companies, 28 to 31.

Musk press conference on Starship/Superheavy launch

8:51 am

Yesterday Elon Musk held an hour-long audio press conference with a number of space reporters, broadcast over youtube. I have embedded that conference below, for those of my readers who wish to hear what Musk had to say, in his own words.

The key take-aways from Musk:

  • The launch was about what he expected
  • They will be ready to launch again in about two months
  • The debris “was really just basically sand and rock so it’s not toxic at all … it’s just like a sandstorm, essentially”
  • The biggest issue is making sure the flight termination system functions better.
  • The next flight will be a repeat, with the main goal getting to stage separation
  • He gives them an 80% chance of making orbit this year

When asked about obtaining the permit for that next flight, Musk side-stepped the question. It remains to my mind the largest obstacle for meeting his schedule.

Radar antenna on Europe’s JUICE probe to Jupiter stuck

8:27 am

European Space Agency officials revealed yesterday that the 52-foot radar antenna on its JUICE probe to Jupiter has failed to deploy as planned, and that they are attempting to shake what they think is a small pin free that is in the way.

Engineers suspect a tiny pin may be protruding. Flight controllers in Germany plan to fire the spacecraft’s engine in hopes of shaking the pin loose. If that doesn’t work, they said they have plenty of time to solve the problem.

Juice, short for Jupiter Icy Moons Explorer, won’t reach the giant planet until 2031. It’s taking a roundabout path to get there, including gravity-assist flybys of Earth and our moon, and Venus.

The radar antenna is needed to peer beneath the icy crust of three Jupiter moons suspected of harboring underground oceans and possibly life, a major goal of the nearly $1.8 billion mission. Its targets include Callisto, Europa and Ganymede, the largest moon in the solar system.

If this antenna cannot be freed, it will prevent JUICE from doing one of its prime missions.

SpaceX successfully launches Falcon 9 from Cape Canaveral

5:39 pm

SpaceX today successfully used its Falcon 9 rocket to put a SES communications satellite into orbit.

The first stage successfully completed its eighth flight, landing on a drone ship in the Atlantic.

The company also attempted to complete a second launch just a little more than three hours later from Cape Canaveral, but the countdown of the Falcon Heavy rocket aborted just 59 seconds prior to liftoff. No word on what happened, though the company has another launch window beginning around 7:30 pm Eastern time tomorrow. If successful it would be the second Falcon Heavy launch in 2023, using two side boosters flying their eighth and third flights respectively. Because of the fuel needs of the payload, neither the side boosters or the core stage will be recovered.

The leaders in the 2023 launch race:

27 SpaceX
16 China
6 Russia
3 Rocket Lab
3 India

American private enterprise now leads China 30 to 16 in the national rankings, and the entire world combined 30 to 28. SpaceX by itself trails the rest of the world, including other American companies, 27 to 31.

Pushback: FIRE sues school for banning students from wearing “Let’s Go Brandon” shirts

2:35 pm

The evil shirt Tri-County Area School officials banned
The evil shirt Tri-County school officials banned

Bring a gun to a knife fight: Because school officials at Tri-County Middle School in Michigan forbid two students from wearing sweatshirts that said “Let’s Go Brandon” on their fronts, even as they permitted other students to wear shirt promoting the queer agenda, the Foundation for Individual Rights and Expression (FIRE) has filed a lawsuit against the schools.

In Feb. 2022, two Tri County Middle School students wore sweatshirts to school with the phrase “Let’s Go Brandon,” a political slogan critical of President Biden with origins in a more profane chant. Even though the political slogan is widely used — multiple members of Congress used it during floor speeches — an assistant principal and a teacher ordered the boys to remove the sweatshirts. However, administrators allowed students to wear apparel with other political messages, including gay-pride-themed hoodies.

The incident is part of a pattern of political favoritism by the school district. When the school district relaxed the dress code for field day, a school administrator ordered a student to stop wearing a Trump flag as a cape, but permitted other students to wear gay pride flags in the same manner.

Glacier layers on the border of Hellas Basin

12:20 pm

Dipping glacial layers
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on February 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as “dipping layers”, referring specifically to the mesas with the terraces on their western flanks.

The layers obviously signify past cycles of geological events on Mars. That the terraces are only on one side of the mesas suggests that they are tilted, with the downhill grade to the east.

These layers however pose several mysteries. First, why are they located so specifically in only certain places of this region? It appears that the layered terrain is only found in the lower hollows and valleys. Why?

Second, why are they tilted at all?

Maxar’s Worldview-3 satellite snaps in-orbit pictures of Landsat-8 satellite

10:13 am

Landsat-8 as seen by Maxar's Worldview-3
Click for original short movie.

Using its high resolution imaging capability, mostly designed to do Earth observations, Maxar engineers took a series of pictures of NASA’s Landsat-8 satellites when the two satellites happened to pass reasonably close to each other. One of those pictures, a screen capture from the short movie that Maxar created, is to the right.

Maxar Technologies’ Worldview-3 satellite has delivered images of NASA’s Landsat 8 spacecraft from ranges of between 56 miles (91.4 kilometers) and 80 miles (129.9 km), showing clear details of the powerful Earth-observation satellite. A still image reveals the 29.5-by-1.3 foot (9 by 0.4 meters) solar array powering Landsat 8, as well as distinct science payloads on the satellite’s 9.8-foot-long (3 m) bus, or main body.

Both satellites are in similar, near-polar orbits, with Worldview-3 circling around 381 miles (613 km) above Earth, while Landsat has a higher altitude of 437 miles (703 km).

Though very cool, this image was taken by Maxar to sell the company’s capabilities to future customers. The military wants the ability to do surveillance of foreign satellites, while satellite companies often need to get such imagery of their satellites to assess their condition. Maxar has now proven it can provide this service to both.

Big space Raytheon shifts gears to compete in the new space market

9:55 am

Capitalism in space: Raytheon, a traditional big space contractor focused mostly on winning military contracts, has decided to shifts gears from what has in recent years been a failed effort to compete for major contracts direct from the military and instead offer its capabilities to other commercial space companies.

This decision was fueled largely by the approach of the military’s Space Development Agency (SDA) to commercial contracts.

SDA’s approach to buying satellites from multiple prime contractors under fixed-price contracts is “revolutionizing space acquisitions,” [Raytheon official David Broadbent] said. The agency has been a “huge disrupter,” he said.

“Let’s call it what it is,” Broadbent added. “Raytheon and many of our traditional defense primes were constructed around sole source classified cost-plus businesses, and five to seven-year acquisition cycles.” Those markets no longer exist, he said. “So we’ve had to take a very hard look at ourselves … and drive to a far more efficient model of producing capabilities.”

In other words, Raytheon has recognized that the government golden goose of unlimited cost-plus contracts is gone, and that the company’s over-priced habits under those contracts made it difficult for it to compete against new startups designed to be efficient, low-cost, and quick on their feet.

By marketing its available products directly to other satellite and rocket companies, Raytheon can avoid the long contract competitions of the government, and make sales more effectively. As it does this it will also have time to restructure the company itself, trimming it down and making it more efficient so that it can better compete for government contracts at a later time.

Raytheon’s change is the result of the SDA essentially accepting many of the recommendations put forth in my 2017 policy paper, Capitalism in Space (a free pdf download). Rather than have the military the designer and builder of a few big and expensive satellites (also very vulnerable to attack), it is now the customer buying constellations of many small and cheap satellites from many private companies. Such smallsat constellations are much more difficult to disable by hostile powers.
