Celestron to modify commercial amateur telescope for space use

9:19 am

Capitalism in space: Amateur telescope manufacturer Celestron has signed a deal to adapt one of its more expensive ground-based telescopes for use in space.

Trans Astronautica Corp. announced an agreement Sept. 27 with telescope manufacturer Celestron to develop a space-qualified version of the company’s Rowe-Ackermann Schmidt Astrograph (RASA) ground-based telescope. “We’ve been using Celestron’s RASA telescopes in our space domain awareness and asteroid prospecting systems, and we found them to be very affordable, high-quality optical systems,” Joel Sercel, TransAstra founder and CEO, told SpaceNews. “We looked at the designs and we realized it would not be that hard to adapt them for space use.”

Over the next year, TransAstra plans to modify the RASA telescope design and substitute materials to produce a telescope that can withstand radiation exposure, temperature swings, and the vibration and shock loads of space launch.

TransAstra provides tracking data on space junk to both the commercial and defense industry. It also has a new deal to use its telescopes to provide schools use of these telescopes for educational purposes. The goal is to put this capability into orbit.

The future ramifications however are profound. Once Celestron has a commercial relatively inexpensive telescope capable of operating in space (or on the Moon), it will not take long before customers begin lining up eager to buy and launch it. Think about it: though there will be engineering issues to overcome, the cost of placing one of these telescopes on one of the new commercial lunar landers for operation on the Moon will not be far beyond the budgets of many amateur astronomers, some of whom spend hundreds of thousands of dollars on their own ground-based observatories.

Radar data from Zhurong finds no ice to a depth of 260 feet

9:46 am

Zhurong's ground-penetrating radar data

Overview map

Chinese scientists today finally published their results from the ground-penetrating radar instrument on their Mars rover Zhurong, revealing that to a depth of 260 feet (80 meters), it detected no clear signal of water ice.

Figure 2 of their paper, posted above, summarizes their results. It shows the radar profile to 328 feet (100 meters) depth along Zhurong’s route, as shown in the map to the right, with the last bit of its recent travels ending somewhere in the blue circle. From the paper:

Our low-frequency radar imaging profile shows radar signals within the depth range of 0–80 m (Fig. 2a), precluding the existence of a water-rich layer within this depth range as the existence of water would strongly attenuate the radar signals and diminish the visibility of deeper reflections. The estimated low (less than 9) dielectric permittivity (Fig. 2c) further supports the absence of a water-rich layer as water-bearing materials typically have high (greater than 15) dielectric permittivity.

We further tested this assessment with thermal considerations by conducting a heat conduction simulation based on available thermal parameters estimated from previous studies (Methods). Our thermal simulation results … show that the Zhurong landing area has an annual average temperature of around 220K in the RoPeR detection depth range, which is much lower than the freezing point of pure water (273K), and also lower than the eutectic temperatures of typical sulfate and carbonate brines, but slightly above those of perchlorate brine systems. This observation suggests that the shallow subsurface of the Zhurong landing area could not stably contain liquid water nor sulfate or carbonate brines, consistent with the radar imaging result.

The data suggests that below the surface topsoil layer, the regolith, there are two distinct layers of material that the scientists interpret as possible evidence of past catastrophic floods. That conclusion however is very very uncertain. The main take-away is that in the northern lowland plains of Utopia Planitia at 25 degrees north latitude, where Zhurong landed, Mars is definitely a dry desert, with no water close to the surface.

This data also suggests that if you establish a colony anywhere in Mars’ dry equatorial regions within 30 degrees latitude of the equator, you will likely have to travel north or south a considerable distance to get to easily accessible ice. The global map of Mars below shows the regions where ice is most evident, north and south of 30 degrees latitude.

Two Chinese launches: Long March 2D and Long March 6 put satellites into orbit

9:16 am

China successfully completed two launches in the past twelve hours, placing four satellites into orbit in total.

First, in the evening of September 26th, a Long March 2D rocket launched a “remote sensing” satellite into orbit. This was then followed in the morning of September 27th with the launch of a Long March 6 rocket, putting three “experimental” Earth observation satellites into orbit. We know nothing more about any of these satellites.

The article at the link lists a third launch, of a Kuaizhou-1A rocket, but I have already reported that.

The leaders in the 2022 launch race:

43 SpaceX
41 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise still leads China 60 to 41 in the national rankings. Against the entire world combined, the U.S. now trails 60 to 61.

September 26, 2022 Quick space links

2:56 pm

Courtesy of stringer Jay, who trolls Twitter so I don’t have to.

Mostly shows views of the Earth.

At the link the reason given is the “problems with the delivery of foreign-made parts.” Or to put it more bluntly, the sanctions against Russia due to its unprovoked invasion of the Ukraine has blocked many sophisticated computer parts that Russia cannot make itself.

All fantasy at this point. Russia’s been promising a next generation capsule replacing Soyuz for more than a decade.

Video at the link. The test occurred on September 23, 2022. No word yet on when they plan to launch.

Astroscale to partner with UK companies to develop mission to remove two defunct orbiting satellites

9:44 am

Capitalism in space: The Japanese-based company Astroscale has signed an agreement with the United Kingdom’s space agency to develop a mission — in partnership with a number of UK companies — to remove two defunct orbiting satellites.

The COSMIC mission will be developed in collaboration with 10 UK-based partner companies in England, Scotland and Northern Ireland including: MDA UK, Thales Alenia Space UK, Nammo, GMV-NSL, NORSS, Goonhilly, Satellite Applications Catapult, Willis Towers Watson, and other advisory and industrial partners.

What Astroscale brings to the table is its magnetic capture system that it has already tested in orbit.

This is also the second contract Astroscale has won in Europe for its space junk removal technology. In May it signed a deal with OneWeb to de-orbit two of its satellites.

China’s Kuaizhou-1A rocket launches two satellites

9:36 am

Early today China’s smallsat Kuaizhou-1A rocket successfully launched two “experimental” satellites into orbit from an interior spaceport.

The satellites are part of a classified program, so little is known about them.

The leaders in the 2022 launch race:

43 SpaceX
39 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise still leads China 60 to 39 in the national rankings and the entire world combined 60 to 59.

Tomorrow ABL Space will attempt to launch from Alaska its RS1 smallsat rocket for the first time. Later in the week Firefly will make its second attempt to launch its Alpha rocket successfully. I will embed the live streams, if available.

SpaceX successfully launches 52 Starlink satellites

4:42 pm

Capitalism in space: Using its Falcon 9 rocket SpaceX today successfully put another 52 Starlink satellites into orbit.

The first stage successfully landed on a drone ship in the Atlantic, completing its fourth flight. The two fairing halves each completed their fourth and fifth flights, respectively.

Note: The Biden administration yesterday gave SpaceX the okay to activate Starlink in Iran, in order to provide that country’s citizens an option for obtaining information blocked by its government.

The leaders in the 2022 launch race:

43 SpaceX
38 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise now leads China 60 to 38 in the national rankings, and the entire world combined 60 to 58.

ULA’s Delta Heavy successfully launches spy satellite for NRO

3:38 pm

ULA today has successfully launched a spy satellite for the National Reconnaissance Office from Vandenberg Space Force Base in California, using its Delta Heavy rocket, its largest rocket.

With this launch, ULA retires the Delta from any further launches from Vandenberg. Future California launches will use its as yet untested Vulcan rocket.

The leaders in the 2022 launch race:

42 SpaceX
38 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise now leads China 59 to 38 in the national rankings, and the entire world combined 59 to 58. The 59 launches makes this the third most active launch year in American history, trailing only 1966 (70 launches) and 1965 (64 launches).

SpaceX has a Falcon 9 launch of 52 Starlink satellites scheduled very shortly, so these numbers will hopefully go up again before the day is out.

Two launches from U.S. set for this afternoon

10:29 am

Both ULA and SpaceX have planned launches this afternoon a little over an hour apart, at 2:53 pm and 4:10 pm Pacific time respectively.

The ULA launch is first, and is the last Delta rocket launch from Vandenberg Space Force base. The company is slowly phasing this rocket out as it transitions to its not-yet-launched Vulcan rocket. The payload today is a spy satellite for the National Reconnaissance Office, using ULA’s biggest rocket, the Delta Heavy.

SpaceX will follow with another Falcon 9 Starlink launch, placing another 52 Starlink satellites into orbit.

I have embedded the live streams of both launches below.

Indian smallsat rocket startup hopes to complete 1st launch this year

10:16 am

The new colonial movement: A new Indian private commercial rocket startup, Agnikul, now hopes to complete the first launch of its Agnibaan rocket before the end of 2022.

Whether or not this launch happens this year, the important thing is the existence of this private independent rocket company in India. Up until now, India’s government space bureaucracy in ISRO, and in its new commercial arm, NSIL, has controlled all of that country’s commercial market share. Like NASA before 2008, it has worked aggressively to keep independent players out.

Agnikul’s existence suggests the Modi government’s effort to emulate the U.S. and create an independent private space industry is beginning to bear fruit. If so, expect big things over the next decade from India in space.

Voyager Space signs cooperative deal with Azerbaijan

9:21 am

Capitalism in space: Voyager Space, the subsidiary of Nanoracks that is building its Starlab private space station, has signed a cooperative agreement with Azercosmos, Azerbaijan’s space agency.

The press release is very vague about what the deal entails.

This strategic multi-year collaboration paves the way for Azercosmos and Voyager Space to proactively develop mutually beneficial space infrastructure, technology, and manufacturing initiatives, research programs, and further opportunities for innovation. With the potential to exchange experience and knowledge, the organizations will focus on commercial and educational opportunities in-country to foster a thriving local space ecosystem.

I suspect it will eventually lead to Azerbaijan sending research payloads to Starlab, once it is in orbit and operational.

The number of recent deals made by American private space companies, either to fly foreign astronauts in space, provide payload space on planetary missions, or provide space station capabilities for foreign science research, is beginning to be difficult to count. With at least four different American private space stations under construction, with at least one more proposed, the rush to sign up customers by these companies is accelerating.

Expect the business to be very brisk once these get launched. It appears that practically every government on Earth wants to claim it has a space program, and buying space and seats from these American commercial companies is going to be the quickest and cheapest way to do it.
