India outlines new schedule for lunar and manned missions

10:07 am

According to press statements by India’s Minister for Science & Technology, Jitendra Singh, the schedule for that country’s next unmanned lunar lander/rover and its first manned missions have now been firmed up.

First, Singh announced that the lunar lander/rover, Chandrayaan-3, is now aiming for a launch to the Moon in the second quarter of ’22. The mission is essentially a rebuild of Chandrayaan-2, which got within a few hundred feet of the lunar surface before losing control and crashing in 2019. Chandrayaan-3 had initially been scheduled for launch in late 2020, but the COVID panic essentially shut down India’s entire space industry in both ’20 and ’21.

Second, Singh announced that India’s manned orbital Gaganyaan mission is now scheduled for launch in ’23.

Jitendra Singh said that the major missions like Test vehicle flight for the validation of Crew Escape System performance and the 1st uncrewed mission of Gaganyaan (G1) are scheduled during the beginning of the second half of 2022. This will be followed by a second uncrewed mission at the end of 2022 carrying “Vyommitra” a spacefaring human robot developed by ISRO and finally the first crewed Gaganyaan mission in 2023.

Like Chandrayaan-3, Gaganyaan was delayed significantly by the panic in India over COVID. It was originally scheduled for launch in December ’21, but the panic caused all work to stop for most of ’20 and ’21. During that time period India’s planned annual launch pace of 6 or more launches per year shrank to a mere three launches over two years, with little sign yet that ISRO is ready to resume launches.

Hopefully, these announcements are a signal that India will fully return to flight in ’22. Stay tuned.

Orbex begins construction of launch platform

9:52 am

Capitalism in space: Orbex announced today that it has awarded a contract to a Scottish company to begin the construction of the launch platform it will use with its smallsat Prime rocket.

Orbex has commissioned Motive Offshore Group, a leading Scottish company specialising in the design and manufacture of marine and lifting equipment, to fabricate and install the Launch Platform at a dedicated test site near Kinloss, close to the Orbex headquarters in Forres, Scotland.

The Launch Platform, known as Orbex LP1, is expected to be fully operational by early 2022. … The new Launch Platform will support the testing of Orbex´s Prime rocket, a micro-launcher designed to transport small satellites weighing around 150kg to low Earth orbit. Although actual launches of the Orbex Prime rocket will not take place at the Kinloss site, the Launch Platform will be fully capable of launching an orbital rocket, allowing for full ‘dress rehearsals’ of launch procedures.

This platform is likely similar to the very transportable launch platform used by Astra. The present plan is to do launches from Orbex’s launch facilities at the Sutherland spaceport in Scotland, presently under construction and the first such launch facility being built in the United Kingdom in more than a half century. If designed to be portable, however, Orbex will also be able to ship the Prime rocket to other launch locations, depending on the orbital requirements of each launch.

Stratolaunch wins military research contract

9:39 am

Capitalism in space: Stratolaunch announced today [pdf] that it has won research contract with the Missile Defense Agency to provide a testing capability to that agency’s program to develop hypersonic flight technology.

The Stratolaunch team is eagerly preparing to complete its next set of Roc carrier aircraft test flights. The team also continues to make tremendous strides in building its first two Talon-A test vehicles: TA-0 and TA-1. TA-1 will start its power-on testing by the end of year, keeping the company on track to begin hypersonic flight testing in 2022 and to deliver services to government and commercial customers in 2023. Launched from Stratolaunch’s Roc carrier aircraft, the Talon-A vehicles are rocket-powered, autonomous, reusable testbeds carrying customized payloads at speeds above Mach 5.

From this release it appears that the company is planning more flight tests of its giant Roc airplane while it begins the first ground tests of the test vehicles that Roc will take into the air, followed in ’22 with flight tests, followed next with operational test flights in ’23.

The company’s shift from using Roc as a first stage for orbital satellites to using it instead as a hypersonic test bed seems to be paying off. For years the company was unable to find any design for second stage rocket that made both technical or economic sense. Using Roc instead as a vehicle for launching a hypersonic test bed — the Talon — seems more practical, while also providing the military a relatively cheap capability for hypersonic testing that it had previously lacked.

NASA issues vague update on Lucy’s solar panel deployment issue.

9:29 am

Lucy solar panel graphic

NASA today released a very vague update describing the work of the Lucy engineering team in trying to work out a fix to the incomplete deployment of one of Lucy’s solar panels.

A project team completed an assessment Dec. 1 of the ongoing solar array issue, which did not appear to fully deploy as planned after launch in late October. Initial ground tests determined additional motor operations are required to increase the probability of the latching Lucy’s array in place as intended, and the team has recommended additional testing.

Spacecraft operations included discharging and charging the battery while pointed at Earth, moving the spacecraft to point to the Sun, operating the solar array motor with the launch day parameters, moving back to pointing at Earth, and then another battery discharge and recharge. The solar arrays charge the batteries, then the batteries are deliberately discharged, and the solar array circuits are used to recharge the batteries; performing these charging and discharging processes gives the team more information about the solar array circuits.

The team gathered information on two of the 10 gores – the individual solar array panel segments that make up the full array — that previously had no data. NASA now has data on all 10 gores confirming they are open, producing power as expected, and not stuck together. [emphasis mine]

Apparently they have been doing a variety of testing of the array to assess its precise condition. The highlighted words are the most important, as this data suggests that all ten fan sections, as shown in the graphic above, are partly open, and that an attempt to fully deploy the solar panel should work.

The Lucy team has apparently decided to approach this work very slowly and cautiously, that they have time to do so as Lucy continues its slow journey to Jupiter’s Trojan asteroids.

SpaceX launches NASA X-ray telescope

9:17 am

Capitalism in space: SpaceX early this morning successfully launched NASA’s Imaging X-ray Polarimetry Explorer (IXPE), a small X-ray telescope designed to black holes and neutron stars.

The first stage, making its fifth flight, successfully landed on a drone ship in the Atlantic.

This launch, SpaceX’s 28th for 2021, extends once again the company’s all time record for the most launches in a year by a private company.

The leaders in the 2021 launch race:

46 China
28 SpaceX
21 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

China’s lead over the U.S, in the national rankings has now shrunk to 46 to 45. The launch was the 121st in 2021, making this year tied as the seventh most active year in the history of space, a ranking that is sure to go up before the end of the year.

Rocket Lab successfully launches two more BlackSky Earth observation satellites

5:15 pm

Capitalism in space: Rocket Lab today successfully launched from its launchpad in New Zealand two more satellite for the Earth observation company BlackSky, completing the launch only 21 days after their previous launch, tying the company’s fastest turnaround.

This was Rocket Lab’s fifth launch in 2021, which the company states will be its last this year. At the start of the year it had predicted it would complete this number, so the company has at least matched its expectations for 2021, despite governmental hold-ups in both New Zealand and Wallops Island that slowed the launch pace.

The leaders in the 2021 launch:

46 China
27 SpaceX
21 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

China’s lead over the U.S. in the national rankings is now 46 to 44. SpaceX has a scheduled launch later tonight, so the race between the two countries should continue to tighten.

This was also the 120th successful launch in 2021, the most in a single year since 1984, and making it the ninth most active year in the history of space exploration.

Strange eroded glacial flows in unnamed crater on Mars

Eroded glacial flows in unnamed crater on Mars
Click for full resolution image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on November 1, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a series of strange glacial-like flows coming off the western slopes of the central peak of a 40-mile-wide unnamed crater, located smack dab in what I call Mars’ glacier country, that 2,000 long mid-latitude strip where almost every image shows evidence of glaciers.

The cropped section to the right doesn’t really do these strange flows justice. Make sure you click on the image to see the full resolution version. There are numerous separate flows coming off that central peak. Each appears to show that as time passed, each flow traveled a shorter distance down the mountain, leaving a moraine behind at higher and higher points.

The overview map below provides the context.

Today’s blacklisted American: Colorado Democrats move to blacklist all mascots and imagery honoring the American Indian

11:25 am

American Indian banned by Democrats
The American Indian, banned by Democrats

Blacklists are back and the Democrats have got ’em: After the Democrats controlling the state government in Colorado passed a bill banning the use of any mascot or imagery that makes any reference to any American Indian tribe or cultural icon, a Native American group immediately filed suit, claiming that the policy essentially discriminates against American Indians, banning them from the public sector in all ways.

Colorado Gov. Jared Polis [a Democrat], who is listed as a defendant in the lawsuit, in June signed Senate Bill 21-116 into law, which prohibits public schools from using “a name, symbol, or image that depicts or refers to an American Indian tribe, individual, custom, or tradition that is used as a mascot, nickname, logo, letter, or team name.” Schools with American Indian-themed mascots have until June 1, 2022 to cease use or face $25,000 fines each month for noncompliance, according to the law, which doesn’t apply if a school has an existing agreement with a federally recognized tribe.

The lawsuit, which was filed [in early November] in U.S. District Court by the Mountain States Legal Foundation, a conservative public-interest law firm, is brought by current and former Yuma High School students and the Native American Guardian’s Association (NAGA), a nonprofit that advocates for the recognition of Native American heritage.

NASA upgrades software for monitoring potentially dangerous asteroids

9:59 am

NASA has installed a major upgrade to the software it uses for monitoring, tracking, and predicting the future orbits of potentially dangerous asteroids.

Sentry [the original software used for the past 20 years] was very effective at calculating orbital paths based on how an asteroid is affected by the gravitational pull of the Sun and planets, but there were a few factors that it couldn’t account for. In the long run, these uncertainties can snowball into many possible orbits that may or may not impact Earth.

The Yarkovsky effect, for instance, is where the Sun unevenly heats the surface of an asteroid as it spins, creating thermal forces between the “day” and “night” sides of the rock that can produce thrust. Other times, asteroids that swing past Earth very closely could be nudged into different orbits by the planet’s gravity, changing the paths of their eventual return.

The first Sentry system couldn’t incorporate either of these two factors, meaning that for special case asteroids like Bennu or Apophis, astronomers would have to manually analyze their orbits, which is a complex and time-consuming process.

But Sentry-II is designed to account for things like these. This latest version uses a different algorithm that models thousands of random points within the uncertainty space of an asteroid’s orbit, then figures out which ones have a chance of striking Earth in future. This, the team says, could help find scenarios that have very low probability of impact.

What this upgrade means is that as new asteroids are discovered the software will be able to very quickly calculate with better accuracy any potential impacts in the coming centuries. The results won’t be perfect, but less manual work will be necessary, meaning fewer dangerous asteroids will fall through the cracks.
