Scientists have finally opened the sample capsule from OSIRIS-REx to see the prime asteroid material obtained from the asteroid Bennu during the spacecraft’s touch-and-go sample grab.

The captured material inside the capsule can be seen in the picture to the right. It is the debris inside the ring.

Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of Astromaterials (AIVA) and Joe Aebersold, AIVA project lead, captured this photograph of the open TAGSAM head including the asteroid material inside using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that shows extreme detail of the sample.

Next, the curation team will remove the round metal collar and prepare the glovebox to transfer the remaining sample from the TAGSAM head into pie-wedge sample trays.

The final mass of material will be determined once it is removed and weighed, though the team has already recovered more than 70 grams that had clung to the outside the capsule, which in itself exceeded the mission’s targeted goal.

Ingenuity’s status uncertain but likely healthy

Overview map
Click for interactive map.

Updates from the engineering team that operates the Mars helicopter Ingenuity in the past two days have suggested the helicopter might be in trouble. First the team issued a status update yesterday that indicated communications had been lost prematurely during the helicopter’s 72nd flight.

The flight was designed as a quick pop-up vertical flight to check out the helicopter’s systems, following an unplanned early landing during its previous flight. Data Ingenuity sent to the Perseverance rover (which acts as a relay between the helicopter and Earth) during the flight indicates it successfully climbed to its assigned maximum altitude of 40 feet (12 meters). During its planned descent, communications between the helicopter and rover terminated early, prior to touchdown.

A further update today said that communications had been regained, but also noted that the engineering team still did not have a full understanding of the helicopter’s status.

We’ve reestablished contact with the #MarsHelicopter after instructing @NASAPersevere
to perform long-duration listening sessions for Ingenuity’s signal.

Based on the information released (or lack thereof) from the previous flight, the 71st, it is my sense that the situation is not as dire as these reports suggest, and that the situation might simply be related to issues of communications. Let me explain why I have come to this conclusion.

Jordan Golson – 9 simultaneous SpaceX launches

An evening pause: This video I think is excellent for taking us into the weekend. It shows nine different Starlink launches simulataneously, illustrating in a creative way how incredibly routine and reliable SpaceX’s Falcon 9 has become.

Hat tip Steve Golson.

Today’s blacklisted American: Parents sue school and principal for punishing their son for being a football fan

13-year-old J.A., prepped to cheer for his favorite
local high school football team

They’re coming for you next: The parents of a 13-year-old boy, identified only as J.A., are now suing the school principal who suspended their son for two days and banned him from all future sports activities because the middle-schooler had put on black “warrior” face paint under his eyes and on his cheeks, as football players often do and as shown in the picture to the right, in order to properly cheer for his football team at a game.

The principal of his school, part of the San Diego Unified School District, claimed it was “blackface,” though he never interviewed the boy, this companions, or anyone involved before issuing his banning edicts. For example, the boy had not even known what blackface was prior to this event. Moreover, no one at the game had complained or had been offended, and in fact, one black security guard joked with the boy, saying he should have made the spikes on the side higher, covering even more of his face.

“We’re suing the principal directly, the superintendent and then the people who made the decision to rubber-stamp the principal’s ridiculous decision to suspend J.A.,” Attorney Karin Sweigart said.

JAXA: SLIM soft landing successful but will likely die prematurely after landing

According to managers at Japan’s space agency JAXA, its SLIM lunar lander successfully completed its soft landing on the Moon.

It appears SLIM’s solar cells are not producing power. The spacecraft is presently on battery power, which will only last a few hours. Engineers are presently rushing to download images, taken during descent and after landing. There is also no word yet on whether the two test rovers were successfully released and achieved their test goals.

To precisely determine if the lander achieved its goal to hit a precise landing zone less than 300 feet across will require further analysis, much of which will depend on the images presently being downloaded. At the moment the engineers believe this goal was achieved, however, based on the telemetry already received.

Thus, it appears Japan has managed a soft-landing, something that in the past few years several countries (Israel, Russia, India, United States) and private companies (SpaceIL, Ispace, Astrobotic) have failed to do. Right now Japan appears to be the third nation to succeed in this new round of lunar exploration, joining China and India (which succeeded on its second attempt).

The next lunar landing attempt will be by the American private company, Intuitive Machines. Its Nova-C lander is scheduled for launch on a Falcon 9 rocket in mid-February.

SLIM lands on the Moon

Telemetry after SLIM's landing

According to telemetry data (as shown on the screen capture to the right), Japan’s SLIM lander has apparently landed on the Moon near Shioli Crater, proving its autonomous precision landing system worked as planned.

At the moment however Japan’s space agency JAXA has not yet confirmed that the landing was completely successful. After landing the announcers on the live stream repeatedly noted that though the telemetry indicated it had landed as planned, engineers had not yet confirmed that the lander was still operational. Note how the data to the right suggests the spacecraft is tilted slightly. This tilt appears to match the tilt of the surface, but it could also indicate a problem with communications.

A press conference announcing either a confirmation or a failure will begin shortly at the live stream above.

Chinese pseudo-company successfully completes rocket hop test

The Chinese pseudo-company Landspace successfully completed a rocket hop flight of its Zhuque-3 prototype hopper yesterday, testing vertical take-off and landing in preparation of recovering and reusing the first stage of its rockets.

The hop itself went to 350 meters and performed a small translation maneuver to the landing pad. The hope is called “ZQ-3 VTVL-1” which refers to “Vertical Takeoff – Vertical Landing”. It uses a single TQ-12 methane engine, which is also used on the current ZQ-2 rocket. The engine can throttle between 50-110% of the normal 80 tons of thrust, giving it a throttle range between 40 and 88 tons. The performed flight went on for roughly 60 seconds. The weight of the hopper is 50.3 tons.

Landpace confirmed the landing precision with 2.4 meters, with a landing speed of 0.75 meters per second, at a pitch angle of roughly 0.14 degrees, and a roll angle of 4.4 degrees. The hopper survived the hop and is already being inspected after the flight.

Video of the hop can be viewed at the link. The hopper is almost identical in concept to SpaceX’s Grasshopper test vehicle used by that company, flying with one engine of the same type used in its operational rocket.

If their test program continues as planned, Landspace hopes to begin flying reuseable stages in 2025, with that first stage capable of flying 20 times.

Of all the pseudo-companies in China, Landspace appears to be the most successful. It not only has an operational orbital rocket, Zhuque-2, that has carried satellites into orbit twice (here and here), it is very close to achieving rocket reuseability competitive with SpaceX.

Astrobotic’s Peregrine burns up in Earth’s atmosphere

At about 3:50 pm (Eastern) yesterday, the lunar lander Peregrine, built by the private company Astrobotic, hit the Earth’s atmosphere above the South Pacific and burned up, according to an update from the company.

The mission is over, having failed to reach the Moon due to a ruptured propellant tank caused by a leak in an interior helium tank.

The company was successful in regaining control over the mission after the leak, activating all payloads and getting data back from them, including images and even a short movie. It was also able to communicate with it from lunar distances. It failed however in testing its landing capabilities, its primary mission.
