Air Force limits future launch bidding to SpaceX and ULA
The Air Force today announced that it decided, after more than a year of discussions and negotiations, to limit bidding on all launch contracts for the next five years to only SpaceX and ULA, thus restricting competitive bidding on those contracts.
The awards represent the second phase of the military’s National Security Space Launch program, which is organized by the Air Force’s Space and Missile Systems Center in Los Angeles, California. Four companies — Elon Musk’s SpaceX, ULA, Northrop Grumman and Jeff Bezos’ Blue Origin — bid for the contracts, with the military set to spend about $1 billion per year on launches.
The NSSL awards represent nearly three dozen launches, scheduled between 2022 and 2026. ULA won 60% of the launches, and SpaceX won the remaining 40%.
The award blocks Northrop Grumman and Blue Origin from bidding on these contracts. Expect a lawsuit from these two companies demanding that they have the right to bid, just as SpaceX did several years ago when the Air Force tried to maintain ULA’s monopoly on bidding.
On a very common sense level, this approach by the Air Force (its space operations soon to be taken over by the Space Force) makes little sense. Why restrict bidding? Both Blue Origin or Northrop Grumman expect to have their new rockets operating commercially in the next two years. They should have the right to bid on military launches. The competition will strengthen the launch market, reduce the costs to the military, and give it more redundancy and flexibility.
Based on my research, the only real reason I have ever been able to find for the Air Force’s desire to do this is their inability to deal with their paperwork should more than two bids be received.
Ascraeus Mons, Mars’ second highest mountain
Today’s cool Mars’ image started out when I came across an interesting image of a depression on the northern flank of the giant Martian volcano Ascraeus Mons, the northernmost of the line of three giant volcanoes just to the east of the biggest of all, Olympus Mons.
To provide context I created an overview showing the entire volcano (with the white rectangle showing the location of the depression image), and suddenly realized that this overview might actually be more interesting to my readers. To the right is that overview of Ascreaus, with a scale across the bottom to indicate the elevation of the mountain above what scientists have determined to be Mars’ pseudo sea level.
Notice that this volcano, the second highest on Mars, rises more than 43,000 feet above the surrounding plains. Its peak is estimated to be about 59,000 feet high, making it taller than Mt. Everest by about 30,000 feet (more than twice its height). Its diameter is approximately 300 miles across, giving it a much steeper profile than the higher but more spread out Olympus Mons. The map below shows this mountain in relation to Olympus as well as its nearby partner volcanoes.

The hateful violent Antifa/Black Lives Matter rioters
The new civility: Watch the numerous videos at this link of masked Antifa/Black Lives Matter rioters in Portland as they attack and abuse an old woman using a walker, who simply wants to protect a police precinct building from being vandalized and burnt to the ground.
Remember these facts about what you watch:
1. Democrat Jerry Nadler (D-New York) claims these hateful rioters are “a myth.” Nadler is also typical of most Democratic politicians, who have for the past four years, since Trump was elected, treated these Antifa rioters (now joined by the Marxist, white-hating BLM crowd) as the SS wing of the Democratic Party. While they will sometimes disavow their violence, they do nothing to stop it, since it instills fear and submission among their opponents.
2. Watch and listen. These rioters epitomize hate in every way, in their dress, in their behavior, in their irrational violence, in their bigotry (assuming all who disagree with them are evil). And we are somehow supposed to let them do as they wish, because of the First Amendment?
3. Speaking of the First Amendment, since when did free speech morph into allowing a mob to rampantly loot, burn, and destroy whatever they want? Since when did it include the right to attack cars and even threaten to kill people?
4. Note how our politicians, mostly Democrats but helped by numerous weasel Republicans, have now normalized the wearing of masks, based not on any science but on irrational fear. We have now all been forced to adopt the garb of these hateful thugs. It is as if some mustached national leader required us all to wear armbands carrying the symbol of his political movement, with the threat of arrest if we dare to dissent.
Other than these minor details, everything these Portland “protesters” are doing is wonderful and perfect and must be defended blindly, forever. And don’t dare say otherwise, or you will be doxed and they will come to your home to accost your family and your children.
Hayabusa-2’s future asteroid targets
Link here. There are two prime candidate asteroid targets, both near Earth astroids.
The possible secondary targets include the oblong asteroid 2001 AV43 or the asteroid 1998 KY 26. They’re each about the size of a large house and both orbit the Sun in roughly 500 days. The proposed plan would see Hayabusa 2 arriving at 2001 AV43 in the late 2029 time frame, or reaching 1998 KY 26 in July 2031. Both asteroids have a low enough relative speed relative to the spacecraft to put them within (eventual) reach after Hayabusa 2’s December flyby.
Interestingly, 2001 AV43 will fly 313,000 km from Earth (0.8 times the Earth-Moon distance) on November 11, 2029.
The two asteroids were selected from an initial field of 354 candidates, which was winnowed down based on accessibility and scientific interest. Both are fast rotators, as evidenced by their light curves, each spinning on its respective axis once every 10 minutes. This represents the shortest “day” of any known object in the solar system, suggesting that these asteroids are in fact solid objects and not simply loosely aggregated “rubble piles.” A visit to one of these asteroids would mark the first time a space mission has seen such an enigmatic fast rotator up close.
The asteroid 1998 KY26 is also a possible carbonaceous (C-type) asteroid, and Hayabusa 2’s exploration of such a space rock would be another first.
Going to 1998 KY26 would also require a distant pass of another asteroid. Going to 2001 AV43 would require a fly-by of Venus, which could provide more data on that planet. Based on this information, my guess is that they will opt for 1998 KY26.
The decision must likely be made before Hayabusa-2 drops off its Ryugu samples to Earth on December 6, 2020.
Russia to ship Nauka to Baikonur launch site August 10
Russia now plans to ship its Nauka ISS module to Baikonur on August 10th, three days later than previously planned, where it will begin the final nine months of preparations for launch.
“The stage of electrical tests takes about six months together with preparations because there is a large number of systems. Scheduled operational measures take another three months from this moment to the launch. This involves direct preparations for the launch together with the provision of microbiological protection, fueling and other operations,” he explained.
Nauka will provide the Russians a second toilet on ISS, plus produce oxygen and water (from urine) for six astronauts. It will also become the cabin for a third Russian-flown astronaut, either tourist or professional.
Nauka is a quarter century in the making, its construction having started in 1995. As a government-run project, that pace matches well with SLS, Orion, the James Webb Space Telescope, and many other big government projects not related to space. The goal isn’t to accomplish anything really but to create the justification for fake jobs that can last a lifetime.
OSIRIS-REx preps for final rehearsal of sample grab
The OSIRIS-REx science and engineering team is getting ready for its August 11th final rehearsal of the sample grab-and-go at the asteroid Bennu that it plans to do in October.
If the rehearsal goes right, the spacecraft will descend to within 131 feet of the surface of Bennu as it deploys its equipment as if it would continue down to the surface. It will also fly in formation above the Nightingale sample site when it does this, taking the highest resolution images yet of the surface of the asteroid.
It will then back off, returning to its home orbit farther from Bennu. Engineers will then review what happened, and use that data to prepare for the actual sample grab-and-go, set for October 20, 2020.
SpaceX launches more Starlink satellites
Capitalism in space: SpaceX tonight successfully put two commercial satellites for another customer plus another 57 of its own Starlink satellites into orbit, using a Falcon 9 rocket that was reusing a first stage flying for the fifth time.
This brings the total number of Starlink satellites now in orbit to 595. They also successfully landed the first stage, making it now available for a sixth flight.
19 China
12 SpaceX
9 Russia
4 ULA
The U.S. has retaken the lead from China in the national rankings, 20 to 19.
What do you do when all four engines on a 747 fail in flight?
An evening pause: It actually happened, and it also amazingly has a happy ending.

Slushy floor of southern Martian crater?
Click for full image.
The cool image to the right, rotated, cropped, and reduced to post here, shows the northwest section of the floor of a crater in the southern cratered highlands of Mars, in a mountainous region dubbed Claritus Fossae, located south of Valles Marineris. The photo was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on May 14, 2020.
The entire crater floor appears to be covered by these strings of closely-packed knobs, reminiscent of the brain terrain found in the mid-latitude glacial regions of Mars and thought to be the result of underground ice sublimating upward.
Below is the area in the white box, in full resolution.

California & Space Force to encourage private launches at Vandenberg
Capitalism in space: The state government of California has signed an agreement with the U.S. Space Force to expand private launches facilities at Vandenberg Space Force Base
It appears that the Space Force is aggressively trying to encourage new private launch operations to take flight out of Vandenberg. The article however is very unclear about exactly what this new agreement accomplishes. I could not find its actual text, and from the story all we get is typical government blather:
[Chris Dombrowski, acting director of the Governor’s Office of Business and Economic Development] said the organizations under the [agreement] will develop a “master plan that identifies the required infrastructure, human capital development, governance and financing necessary to support the United States Space Force mission and position California as a leader in the future of the commercial space industry.”
“This MOU serves as a critical investment in California’s innovative economy as we work to safely recover from the COVID-19 induced recession,” he said.
If anything, it appears that California’s Democratic and very power-hungry government is using this agreement to take control of any new private operations, so that it can dictate how they operate, according to its whims. If so, don’t expect much private enterprise to prosper at Vandenberg.
Study: Lava tubes on Mars and the Moon will be gigantic
A new study comparing lava tubes on the Earth with those detected from orbit on Mars and the Moon now suggests that tubes on those other worlds will be many times larger than on Earth.
Researchers found that Martian and lunar tubes are respectively 100 and 1,000 times wider than those on Earth, which typically have a diameter of 10 to 30 meters. Lower gravity and its effect on volcanism explain these outstanding dimensions (with total volumes exceeding 1 billion of cubic meters on the Moon).
Riccardo Pozzobon adds: “Tubes as wide as these can be longer than 40 kilometres, making the Moon an extraordinary target for subsurface exploration and potential settlement in the wide protected and stable environments of lava tubes. The latter are so big they can contain Padua’s entire city centre”.
Moreover, the data suggests their roofs, even at this size, will be very stable because of the lower gravity, making them excellent locations for large human colonies.
The researchers also suggest that there are many intact such lava tubes under the mare regions on the Moon, their existence only hinted at by the rare skylights created due to asteroid impact.
