Hayabusa-2 completes close approach of target/manmade crater

9:21 am

Target on Ryugu's surface

Hayabusa-2 has successfully completed its close approach and reconnaissance of the positioning target it had placed on May 30 near the crater it had created on Ryugu on April 4.

The image to the right is the last navigational image taken at the spacecraft’s closest point. You can clearly see the navigational target as the bright point near the upper center of the image, to the right of the three larger rocks. This location also appears to be inside the manmade crater, based on earlier reconnaissance of that crater. The crater is in an area they have labeled C01, which is where they have successfully placed the target. It also appears that this is the smoothest area in C01, which will greatly facilitate their planned sample grab.

China announces international experiments to fly on its space station

9:04 am

The new colonial movement: China and the UN today jointly announced the nine international experiments that China will fly on its own space station, set to be completed by 2022.

The nine projects involve 23 entities from 17 countries in the fields of aerospace medicine, space life sciences and biotechnology, microgravity physics and combustion science, astronomy and other emerging technologies.

It seems to me that the competition in space is definitely heating up. Both China and Indian now plan their own space stations. And the Trump administration’s announcement that it will allow private commercial and competitive operations on ISS, is certainly going to lead eventually to more than one private station in orbit, plus ISS.

The result is going to be many different stations, all offering different capabilities and all in competition to lower the cost to get there and to do research or to sightsee. All are also going to be contributing aggressively in learning how to build vessels that humans can live on for long periods, which in turn will teach us how to build interplanetary spaceships. In fact, every one of these stations will be prototypes for those interplanetary spaceships.

Isn’t competition wonderful? After almost thirty years of boring international cooperation on ISS, with little new achievement or innovation, the space station competition coming in the next decade will revitalize space exploration in ways we as yet cannot imagine.

India to build its own space station

8:54 am

The new colonial movement: India announced yesterday that it is beginning design work on its own space station, with a plan to begin construction and launch following its first manned mission, dubbed Gaganyaan, in 2022.

Giving out broad contours of the planned space station, Dr. Sivan [head of India’s space agency ISRO] said it has been envisaged to weigh 20 tonnes and will be placed in an orbit of 400 kms above earth where astronauts can stay for 15-20 days. The time frame is 5-7 years after Gaganyaan, he stated.

The announcement came out of the first meeting of what ISRO calls its Gaganyaan National Advisory Council, designed to bring together people from India’s space industry to prepare for that first manned flight in 2022.

Bigelow announces four tourist bookings to ISS using Dragon

8:47 am

Capitalism in space: The private space station company Bigelow Aerospace announced yesterday that it has booked four tourists to spend from one to two months on ISS.

The bookings will fly to ISS using SpaceX’s Falcon 9 rocket and Dragon capsule. Though the company did not say how much these tourists have agreed to pay, it said that it intends to charge $52 million per ticket.

This announcement follows directly from NASA’s announcement last week that it will allow commercial tourist flights to ISS. Previously Bigelow had said it would fly tourists to its own space station using Boeing’s Starliner capsule. Now it is going to take advantage of NASA’s new policy to send the tourists to ISS, and it will use Dragon, probably because Dragon is closer to becoming operational.

I also suspect that Bigelow’s long term plans are to add its own hotel modules to ISS for these flights, and then later follow-up by building its own independent space station.

OSIRIS-REx’s new orbit of Bennu only half mile high

8:39 am

OSIRIS-REx has moved into its next phase of research by lowering its orbit around the asteroid Bennu to only 2,231 feet above the surface.

Upon arrival at Bennu, the team observed particles ejecting into space from the asteroid’s surface. To better understand why this is occurring, the first two weeks of Orbital B will be devoted to observing these events by taking frequent images of the asteroid’s horizon. For the remaining five weeks, the spacecraft will map the entire asteroid using most of its onboard science instruments: the OSIRIS-REx Laser Altimeter (OLA) will produce a full terrain map; PolyCam will form a high-resolution, global image mosaic; and the OSIRIS-REx Thermal Emission Spectrometer (OTES) and the REgolith X-ray Imaging Spectrometer (REXIS) will produce global maps in the infrared and X-ray bands. All of these measurements are essential for selecting the best sample collection site on Bennu’s surface.

The goal is to narrow to four the possible touch-and-go landing sites for grabbing a surface sample. They will pick the final choice in a reconnaissance phase now scheduled for the fall.

The present research phase will last until the middle of August, when they will raise the orbit slightly to give them a different perspective of its surface and the particles being released from it.

India sides with Israel in UN for the first time

6:42 pm

On June 6 the Indian government for the first time voted in support of Israel and its motion against a Palestinian non-governmental organization linked to jihadi terrorist groups.

The vote took place on June 6, just weeks after Prime Minister Narendra Modi and his allies won a two-thirds majority in the Indian general elections. Since Modi took office in May 2014, India has mostly abstained from voting on UN resolutions targeting the Jewish state but has shied away from siding with Israel at the international body.

…By backing Israel at the UN, Prime Minister Modi has finally broken away from the country’s historical voting pattern of siding with the Arab and Muslim countries.

Modi’s landslide election victory probably helped bring about this change of position. I also suspect that Trump’s decision to cut off funds from Hamas and other Palestinian terrorist organizations, while moving the U.S. embassy to Jerusalem, also made it easier for Modi to make this change. Trump has essentially said that the Palestinian emperor has no clothes (ie they are not interested in peace, only killing Jews), and this has allowed many others to chime in as well.

New prediction for upcoming solar cycle

6:20 pm

The uncertainty of science: A new prediction for the upcoming solar cycle, announced today, calls for a much weaker cycle then the general consensus of the solar science community.

The new prediction:

The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle – measured in terms of sunspot number, a standard measure of solar activity level – could be 30 to 50% lower than the most recent one. The results show that the next cycle will start in 2020 and reach its maximum in 2025.

The consensus prediction:

[They] dutifully tabulate the estimates, and come up with a peak sunspot range: 95 to 130. This spells a weak cycle, but not notably so, and it’s marginally stronger than the past cycle. [They do] the same with the votes for the timing of minimum. The consensus is that it will come sometime between July 2019 and September 2020. Maximum will follow sometime between 2023 and 2026.

The main difference is that the consensus expects the next maximum to be weak but stronger than the maximum that just ended, while the new prediction says the next maximum will be the weakest in 200 years.

It has been my impression that there is unhappiness in the solar science community over the consensus prediction. I suspect today’s independent prediction is an indication of that unhappiness. The scientists involved in this research wanted to go on record that they disagree with the consensus.

I expect that NOAA will eventually put the consensus prediction on their monthly sunspot graph that I post here each month. If they do, I might also add this independent prediction so that we can compare the accuracy of the two as the next cycle unfolds.

Hayabusa-2 making close approach of target/manmade crater

5:56 pm

Ryugu during close approach

The Hayabusa-2 science team is right now conducting a close approach of the manmade impact crater they created to get a firm idea of exactly where the navigation target dropped to the surface during the last close approach landed.

The image on the right is the most recent navigation image, taken just a short time ago, and posted here in real time.

Once they have a precise location, they can then plan the touch-and-go sample grab within that man-made crater.

The damp southern latitudes of Mars

11:01 am

Impact craters on the southern permafrost of Mars
Click for the full image.

Cool image time! The image on the right, cropped to post here, was part of the monthly image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO). The release came with no caption, and was merely titled Aonia Terra, indicating that it was part of the vast cratered region ranging from 30 to 81 degrees latitude south of Valles Marineris.

These craters are at the high latitude of 73 degrees, so they are relatively close to the south pole. Based on what I have recently learned about the Martian poles, the higher the latitude the more water you will find saturated in the ground. In many ways one could refer to this ground as a kind of permafrost.

The lander Phoenix landed at about 68 degrees north latitude, slighter farther from the north pole, and was able to find water by merely scraping off a few inches of ground.

Thus, we should not be surprised by the muddy look of these craters. Their bolides landed on ground that was likely saturated with water, and went splat when they hit.

The scientific puzzle is why one crater seems to sit above the general surface, as if the ground resisted the impact, while the other seems to be mostly sunken, as if the ground was so soft that when the bolide hit, it sunk as if it landed on quicksand, leaving only a vague trace of an impact crater.

Don’t ask me for an explanation. I only work here.

China tightens rules for its private space companies

7:16 am

China has released new rules governing the work of that country’s private space companies, tightening its control over them.

[The rules] require companies to obtain official permission before carrying out rocket research and development as well as production, according to a notice published on the web site of the State Administration of Science, Technology and Industry for National Defense on Monday.

The new rules also require a confidentiality system to be established among commercial rocket companies and asks them to follow state export control regulations when in doubt about whether they can provide overseas services and products.

These rules really only codify the control the government has always had over Chinese private companies.
